The construction planning of the purification workshop is closely related to the purification air conditioning system. The purification air conditioning system should not only comply with the overall construction plan, but also conform to the standards of the purification air conditioning system, so as to give full play to the effect of the relevant functions. The planner of purification air conditioning not only knows the construction planning to think about the placement of the system, but also needs to put forward the construction planning to make it fit the principle of purification workshop.

How to plan the purification workshop project

First, the plane planning of purification workshop

Purification workshop usually contains three parts: purification area, quasi-purification area and auxiliary area.

The plane placement of the purification workshop can be done in the following ways:

Corridor surround type: corridor can have Windows and no Windows, and used as viewing and placing some equipment, some in the corridor with on-duty heating. The outer window is necessary to be a double sealed window.

Inner corridor type: the purification workshop is located in the periphery, and the corridor is located in the interior. The purification grade of this corridor is usually higher, even at the same level as the purification workshop.

Two end type: purification area is located on one side, and the other side is equipped with quasi purification and auxiliary room.

Center type: in order to save land and shorten the pipeline, the purification area is the center, surrounded by a variety of auxiliary rooms and shady pipeline space, this method avoids the influence of outdoor climate on the purification area, reduces the cold and heat energy consumption, and is conducive to energy saving.

Second, the person purifies the way

In order to reduce the pollution caused by human activities as much as possible in the operation, it is necessary for personnel to replace the purification clothes and blow, shower and disinfect before entering the purification area. These methods are called "personal purification" or "human cleansing".

The room in which purifying clothes are replaced in the room for people's net use should be supplied with air, and adhere to positive pressure on the inlet side and other rooms, a little positive pressure on the toilet and shower, while negative pressure should be adhered to for the toilet and shower.

Three, material purification road

All kinds of objects in the purification area before it is necessary to go through purification disposal, referred to as "clean".

The material purification road and the clean road should be separated. If the material and the personnel can only enter the purification workshop at the same place, it is necessary to enter the purification workshop separately, and the materials should be processed by rough purification first.

On the production line is not strong occasions in the material road center can be set up a central warehouse.

If the production line is very strong, the straight-through material road is selected, and sometimes the repeated purification and transmission equipment is set in the center of the straight-through road.

In the system planning, during the crude purification and fine purification of the material net room, many particles will be blown off, so the relative purification area should adhere to negative pressure or zero pressure. If the pollution risk is high, the direction of import should also adhere to negative pressure.

Iv. Pipeline organization

The pipeline of purification workshop is very complex, so the shade organization method is selected for these pipelines. Detailed shade organization methods are as follows.

1. Skill layer

(1) Skill layer at the top. In this kind of interlayer, the section of the air supply and return pipe is usually the largest, so it is the first thought target in the interlayer. It is usually organized at the top of the interlayer, under which the electrical pipeline is organized. When the bottom plate of this sandwich can accept a certain component, filters and exhaust equipment can be set on it.

(2) Room skill mezzanine. Compared with the top layer, this method can reduce the wiring and height of the layer, and can eliminate the skills needed for the return air pipeline to return to the layer. I can also set up a return wind power equipment distribution in the alley, a layer of purification workshop on the alley can also do a layer of the lower alley.

1. Skill lane (wall)

The horizontal pipelines in the upper and lower interlayers usually turn into vertical pipelines, and the shady space of the vertical pipelines is the skill passage. The skill tunnel can also be placed in some auxiliary equipment not suitable for purification workshop, and even can be used as the usual return air pipe or plenum, and some can be installed with light tube type radiator.

This kind of skill lane (wall) because most choose lightweight space, so when the skill adjustment, can be easily adjusted.

4. Skill silos

If the skill channel (wall) is usually not more than the layer, then the demand is more than the layer, that is, the skill shaft, and often as a part of the construction structure, with permanent.

Because the skill shaft links all layers together, in order to prevent fire, after the completion of the internal pipeline device, it is necessary to close the fire resistance between layers with the information that the fire resistance limit is not lower than that of the floor, and the maintenance operation is carried out in layers. It is necessary to set fire doors for the maintenance doors

No matter the skill interlayer and skill tunnel are still skill shafts, when directly combined with the style road, it is necessary to dispose of its inner and outer appearance according to the needs of the inner and outer appearance of the purification workshop.

Five, the direction of the computer room

The air conditioning room should be close to the purification workshop with large air supply volume, and strive to have the shortest air duct line. But in order to avoid noise and oscillation, it is necessary to separate the purification workshop from the machine room. Think about both. Isolation methods are:

1. Structural separation method. There are the following:

(1) Settlement joint isolation type. Make the settlement joint pass between the purification workshop and the machine room to have the cutting effect.

(2) clipped wall isolation. If the machine room is close to the purification workshop, it is not a common wall partition, but each has its own partition, and there is a certain width gap between the two-sided partition.

(3) Isolated auxiliary room. An auxiliary room is set between the purification workshop and the computer room to create a buffer effect.

2. Distraction methods. There are the following:

(1) On the roof or on the ceiling lax method: Now the machine room is often located on the top roof of the practice, so that it is far away from the following purification workshop, but the next layer of the roof is best set as the auxiliary or management room layer, perhaps as a skill layer.

(2) underground lax type: the machine room is located in the basement.

3. Independent construction method. In addition to the construction of the purification workshop, the machine room is set up alone, but it is very close to the purification workshop. The equipment room should pay attention to vibration isolation and sound insulation. The ground should be waterproof and have drainage methods.

Vibration isolation: vibration prevention should be done in the support and base of the fan, motor, water pump and other vibration sources, and even if necessary, the equipment should be installed on the concrete plate, and then the vibration prevention data should be used to support the plate. The component of the plate should be 2 to 3 times of the total component of the equipment.

Sound insulation: remove the muffler device on the system, large machine room can think about the wall attached with the sound absorption function of the information, to install the sound insulation door, do not open the door on the wall and purification area.

Six, safe dispersion

Because the purification workshop is built with strong airtightness, its safe dispersion has become very important and prominent questions, and it is also closely related to the setting of the purification air conditioning system. In general, the following points should be noted:

1. Each production layer fire protection area or purification area at least 2 safety exit, as long as the area is less than 50 square meters, personnel less than 5 people, can allow only a safety exit.

2. Net imports should not be decentralized exports. With roads often winding, it was difficult to get people outside quickly once the fireworks started.

3. The shower room can not be used as the usual revenue and expenditure channel, because the door is often two interlocks or active, once the fault occurs, very affect the dispersion, so usually in the shower room with bypass door, it is necessary to set this door when the operator is more than 5 people. Normal operators should not go out of the purification workshop blowing shower room but should go through the bypass door.

4. The door of each purification workshop in the purification area, considering the need to maintain the indoor pressure, its opening direction should be toward the room with high pressure, because the door should be pressed by pressure, which is obviously opposite to the need for safety and dispersion. In order to think about the two aspects of ordinary purification and urgent dispersion needs, the door between the regular purification area and the non-purification area, and the door between the purification area and the outdoor door are treated as the safe dispersion door. The open direction of the door is toward the dispersion direction. Of course, the same is true of the single security door.
