A pollutant partition system based on the principle of air directional flow and its application method

Abstract

The invention relates to a pollutant obstructing system based on the air directional flowing principle and a using method of the pollutant obstructing system. The pollutant obstructing system is composed of a positive pressure air pipe system, a negative pressure air pipe system and an automatic control system. For a positive pressure area, air purified through an efficient filter is fed into the positive pressure area through a booster fan so as to ensure that the air pressure of the positive air pressure area is higher than the standard atmospheric pressure; for a negative pressure area, air is exhausted through a negative pressure draught fan via an extraction opening and discharged through an air outlet end so as to ensure that the air pressure in the negative pressure area is lower than the standard atmospheric pressure. An automatic control terminal is connected with the booster fan, electromagnetic valves, exhaust electromagnetic valves, pressure sensors and the negative pressure draught fan to complete automatic control over the positive pressure air pipe system and the negative pressure air pipe system. According to the pollutant obstructing system based on the air directional flowing principle and the using method of the pollutant obstructing system, pressure gradients are formed due to different requirements for air quality of different functional areas, it can be achieved that positive pressure in different areas is independently controlled, the debugging and operation management work is simplified, and pollutants in the area with a pollution source are effectively prevented from being conveyed to other areas.

Description

technical field [0001] The invention belongs to the technical field of air purification, and in particular relates to a pollutant isolation system based on the principle of directional air flow and a method for using the same. Background technique [0002] With the continuous development of the economy and society, people have higher and higher requirements for the air quality of the area where they live, such as the living environment, industrial production processes and special industries. However, various production and living environments of human beings are always full of various pollution sources, which affect the quality of ambient air and even endanger human health. For example, in the home environment, the kitchen is the focus of air quality control. The common pollutants in the general kitchen cooking process include benzopyrene, carbon monoxide, inhalable particulate matter, nitrogen oxides, etc. [1] , They are poorly ventilated or not ventilated in the kitchen, ...

AI Technical Summary

Problems solved by technology

[0003] In the traditional method, the method of solving the airflow exchange between the air quality control area and the external air pollution source is mainly by closing the pollution source and the pollution area, or closing the air quality control area. This method has many shortcomings and defects

For example, in the bathroom and kitchen in the family residence, the door is closed to prevent the air from the polluted area from spreading to the surroundings. However, due to the limited airtightness of the room, it will inevitably have a certain impact on the living room and bedroom. It cannot be guaranteed that the polluted gas can be completely isolated from other areas, and the closed polluted area will cause great inconvenience to the flow of people.

Laboratories are generally equipped with fume hoods, fume hoods, etc., but this is only for the removal of pollutants during some specific experimental operations
