Problems solved by technology

[0008] In order to solve the problem that the existing harmful bacteria in the indoor ambient air lack mechanical elimination technical measures, the purpose of the present invention is to provide a method for constructing and using an indoor air filtration and purification system, which can be used independently to eliminate harmful bacteria in the indoor ambient air. Bacteria can be eliminated mechanically, or the ventilation pipe network system can be shared with the existing air-conditioning system to disinfect, sterilize and filter the airflow in the air-conditioning fresh air (supply air), exhaust air (return air) and exhaust system

Embodiment 1

[0092] A method for constructing and using an indoor air filtration and purification system, comprising the following steps:

[0093] 1) Build an equipment collection platform for indoor air filtration and purification systems (such as figure 1 , figure 2 shown)

[0094] The indoor air filtration and purification system includes equipment collection platform A and equipment collection platform B, the main air supply duct drawn from equipment collection platform A, the main exhaust duct drawn from equipment collection platform B, and the main air supply duct derived from the main air supply pipeline Several air supply branch pipes with air outlets, and several exhaust air branch pipes with return air outlets derived from the main exhaust pipe are used for the fresh air (supply air), exhaust air (return air) and exhaust air of the indoor air filtration and purification system. The airflow in the wind system is filtered and purified, and the equipment collection platform for t...

Embodiment 2

[0109] On the basis of Example 1, step 1) in ③: the air outlets of each air supply branch pipe are installed at the upper part of the room and at the space point close to the "protection point" (healthy person), and the return air outlets of each exhaust air branch pipe are installed at The room is close to the floor and is close to the "suspicious point" (potential source of risk of transmitting germs), ensure that the air outlet and the return air are formed between the air outlet and the return air. , to ensure that the air flow formed in the room is first blown to the "protection point" in the upwind position, and then blows to the "suspect point" in the downwind position.

Embodiment 3

[0111] On the basis of embodiment 1, an ozone generator is connected in the main exhaust duct (i.e., the system return air duct) 34 of the air filtration and purification system to realize the prevention of adhesion of various germs to the inner wall of the main exhaust duct, the exhaust branch pipe, and the return air outlet. Mechanical disinfection operations (such as image 3 shown):

[0112] 1) The main exhaust pipe, exhaust branch pipe and the air inlet on it are all made of PVC plastic material instead of metal material;

[0113] 2) Set a ventilation branch pipe 16 with a pipeline control valve 15 at the air inlet end of the exhaust fan 2 in the equipment collection platform B, and the ventilation branch pipe 16 is connected with an ozone generator 17 to form a new equipment collection platform C:

[0114] 3) Perform a seamless functional transition between the operation of the indoor air filtration and purification system and the mechanical injection of ozone into the ...

Abstract

The invention relates to a method for constructing and using an indoor air filtration and purification system. It is characterized in that it includes the following steps: 1) Constructing an air filtration and purification integrated equipment system platform: ① Set an equipment assembly platform A at the beginning of the main air supply pipeline: including a blower, an air outlet of a three-way pipe connected in series behind the air inlet of the blower, The air inlet pipe with the pipe control valve installed in the three-way pipe is connected to the ambient atmosphere, the air inlet pipe with the pipe control valve in the three-way pipe is connected with the secondary filter and purification tower, and a primary filter is connected in series behind the secondary filter and purification tower A blower is connected in series behind the purification tower and the first-stage filtration and purification tower; ② Set up an equipment collection platform B at the beginning of the main exhaust duct: the exhaust port including the exhaust fan and the exhaust fan is connected in series with the air inlet of the three-way pipe, and the three-way pipe The air outlet pipe with the pipe control valve is connected to the ambient atmosphere, and the outlet pipe with the pipe control valve in the three-way pipe is connected to the air inlet of the primary air filtration and purification tower. The method can mechanically eliminate germs in the indoor ambient air.

Description

technical field [0001] The present invention relates to a method for constructing and using an indoor air filtration and purification system (or a method for indoor air filtration and purification), involving air filtration and purification in indoor spaces, disinfection and sterilization of polluted air, and functional upgrades of traditional central air-conditioning systems . Background technique [0002] The crowd gathering places inside various buildings are equipped with ventilation and central air-conditioning systems (hereinafter referred to as air-conditioning systems). And the air distribution device is composed of three parts. In addition, there are refrigeration systems, heating systems and automatic adjustment systems. The traditional air-conditioning system with fan coil unit plus fresh air unit, centralized constant air volume air-conditioning system and variable air-volume air-conditioning system usually adopts the air-conditioning mode of ceiling air supply...
