Description

Indoor air purification system

Technical Field

The invention belongs to the technical field of air purification, and relates to an indoor air purification system.

Background

In daily life, people cannot avoid being in some gathering indoor environments, such as: family gatherings, restaurant gatherings, public places, hospitals, offices, etc., where people tend to be harmed by indoor dirty air, such as: indoor bacteria, viruses, formaldehyde, second-hand smoke, carbon dioxide exhaled by people, MP2.5, harmful gases generated in production workshops and the like; even if the existing ventilation and air exchange system is installed indoors, a horizontal air flow phenomenon still occurs between the air inlet and the air outlet, and as long as the indoor air flows horizontally, people at different positions of the indoor body can suck dirty air to different degrees, such as: infectious virus or second-hand smoke is turbid in the gas aerosol exhaled by people, is diffused in indoor air, and can be inhaled by people going down the wind. The solution is that the transverse flow of indoor air must be stopped, so that people can inhale clean air all the time, and the exhaled foul air can be discharged immediately; in the indoor environment, a plurality of brand-new air purification and ventilation systems are adopted, for example, fresh air is injected into the lower part of the room, and dirty air is exhausted from the upper part of the head of a person in the environment; in whole indoor, use the aerodynamics principle, with indoor air inlet blow upwards perpendicularly on ground, indoor top is equipped with the gas collecting channel, and indoor foul smell is inhaled all the time to outdoor through air pipe again, lets indoor air vertical flow upwards promptly.

Summary of the invention

In view of the above problems in the indoor air purifying and ventilating system, the present invention provides an indoor air purifying system, which can effectively solve the above problems in the background art.

In order to achieve the purpose, the invention provides the following technical scheme:

first, explanation is made: according to the indoor air purification system provided by the invention, due to different application scenes and different use purposes, the structure of the indoor air purification system and the equipment in the system can be different, and the variety and the number of the equipment can be increased or decreased; in some specific occasions, besides the requirement of purifying indoor air, a set of negative oxygen ion machines must be added to increase indoor negative oxygen ions, and a set of heat exchanger must be added to increase indoor and outdoor cold air or hot air loss; however, the general principle is not changed, namely the flow direction of the indoor fresh air is vertical and upward, the indoor dirty air is discharged immediately, and the indoor air does not have the chance of staying. The technical solution provided by the present invention is described in several different scenarios below.

1. An indoor air purification system used in public places comprises a draught fan, a fresh air purification and disinfection device, a fresh air pipeline, an air blower, a fresh air wall-through pipeline, a fresh air distributor, a fresh air branch pipeline, a fresh air injection pipeline, a gas collecting hood, an exhaust pipeline, an exhaust main pipeline, an exhaust wall-through pipeline, an exhaust disinfection device, an outdoor exhaust pipeline and an exhaust fan; the whole set of indoor purification and ventilation system comprises four parts, namely an outdoor fresh air system, an indoor exhaust system and an outdoor exhaust system; the outdoor fresh air system is connected with a fresh air purifying and disinfecting device through an induced draft fan, the fresh air purifying and disinfecting device is connected with a fresh air pipeline, the fresh air pipeline is connected with an air blower, the air blower is connected with a fresh air wall-penetrating pipeline, the indoor fresh air system is connected with a fresh air distributor through a fresh air wall-penetrating pipeline, the fresh air distributor is connected with fresh air branch pipelines, the fresh air branch pipelines are connected with fresh air injection pipelines, the indoor air exhaust system is connected with an air exhaust pipeline through a gas collecting hood, the air exhaust pipeline is connected with an indoor air exhaust main pipeline, the indoor air exhaust main pipeline is connected with an air exhaust wall-penetrating pipeline, the outdoor air exhaust system is connected with an air exhaust disinfecting device through an air exhaust wall-penetrating pipeline, the air exhaust disinfecting device is connected with an outdoor air exhaust pipeline, and the outdoor air exhaust pipeline is connected with an air exhauster; in addition, the roller shutters can be additionally arranged on the periphery of the edge of the gas collecting hood, so that an independent space can be formed, and the air purification effect is more accurately enhanced.

2. In some scenes, only indoor simple purification is needed, for example, indoor second-hand smoke, people's exhaled foul smell, indoor formaldehyde solubility reduction and the like, and then the simple indoor air purification system can be adopted. The simple indoor air purification system can also increase or decrease equipment according to different requirements; the simple indoor air purification system comprises a gas collecting hood, an exhaust pipeline and an exhaust fan; the gas-collecting hood is arranged above the head of a place where a person stays for a long time, the negative pressure in the gas-collecting hood sucks in foul air exhaled by the human body and indoor air, and the foul air and the indoor air are directly exhausted out of the room or a special exhaust purification device through an exhaust fan and an exhaust pipeline.
