Embodiment Construction

[0021] The inventive idea of ​​the treatment method of the present invention is: to pass fresh air into one side of the relatively closed space, and use a fan to draw out the air flow on the other opposite side, and to control the ratio of the fresh air flow rate to the air flow rate so that a self-contained air flow is formed in the relatively closed space. The directional airflow that flows sideways to the position of the fan keeps the enclosed space in a negative pressure state, so that the aerosol in the space can flow to the airflow processing unit along with the airflow direction, and then be filtered and sterilized by the processing unit and then discharged into the outside atmosphere . The operation of each component of the airflow processing unit of the present invention is controlled and implemented by the electric control unit of the present invention. The present invention will be described in further detail below in conjunction with specific embodiments.

Abstract

The invention relates to a method for treating harmful aerosol in a relatively sealed space, which comprises: (a) forming a fresh air supply opening in a side wall which forms the relatively sealed space, and charging fresh air into the relatively sealed space from the fresh air supply opening; (b), arranging an air flow processing unit on the side, opposite to the fresh air supply opening, of the relatively sealed space, wherein the air flow processing unit comprises a sealed tank box arranged on the side wall of the relatively sealed space and a filtering and sterilizing device and a fan which are arranged in the seal tank body in turn along the flowing direction of the air flow, and the sealed box body is provided with an air outlet channel; and (c) controlling the ratio of the inlet air volume at the fresh air supply opening to the air outlet volume discharged from the air outlet channel to generate an oriented air flow flowing from the fresh air supply opening side to the air flow processing unit in the relatively sealed space, wherein the oriented air flow is discharged into the atmosphere from the air outlet channel after passing through the air flow processing unit. The method of the invention can effectively avoid the diffusion of the aerosol and has better treatment effect and low cost.

Description

technical field [0001] The invention belongs to the technical field of environmental purification, and in particular relates to a treatment method for treating harmful aerosols in a small space. Background technique [0002] In the prior art, the routine treatment of high-concentration aerosols in a specific space is to use a fan to extract them, directly discharge them to the outside of the space, and reduce the concentration by diluting the atmosphere. There is no treatment for the quality of the discharged air, and while the space air is drawn, the same flow of air is supplemented into the space. The pressure difference inside and outside the space is 0, which is an equal pressure area. This is completely feasible for harmless aerosols or beneficial bacteria, but if the aerosol is something that can be transmitted through the air, such as the patient's saliva aerosol containing influenza A bacteria, if the above method is used, the harmful aerosol will be Spread around ...
