Combined waste gas filtering tank

Abstract

The invention discloses a combined waste gas filtering tank and belongs to indoor ventilation equipment. The combined waste gas filtering tank comprises a tank body, wherein the tank body is provided with an air inlet and an air outlet; the box body is internally provided with drawer type separation layers for mounting filtering core materials; the drawer type separation layers are arranged between the air inlet and the air outlet; at least two drawer type separation layers are arranged; the filtering core materials at least comprise active carbon and an SDG (Secoisolariciresinol Diglucoside) adsorbent; and the active carbon and the SDG adsorbent cover the drawer type separation layers respectively to form a filtering section and an adsorption section in the tank body. The drawer type separation layers are arranged in the tank body so that a plurality of types of core materials for filtering or adsorbing can be mounted in the tank body, and various harmful components in waste gas can be conveniently treated, and furthermore, the filtering effect of waste gas is improved and the core materials can be conveniently replaced by adopting a drawer type structure; and a pressure difference of gas flows passing through the tank body is monitored in real time through a pressure difference alarm, so that the flow speed of the waste gas flowing through the tank body is in a controllable range and a condition that the flow speed is too rapid to affect the filtering effect of the core materials on the waste gas is avoided.

Description

technical field [0001] The invention relates to an indoor ventilation device, more specifically, the invention mainly relates to a combined exhaust gas filter box. Background technique [0002] At present, the laboratory filter equipment on the market generally only performs a single treatment for certain types of waste gas, either effective for acidic and alkaline gases, or effective for organic gases; Good filtering effect; moreover, the structure and volume of the existing various gas filtering devices are huge, the installation site is limited, and it is inconvenient to maintain during use, so it cannot be accepted by the majority of users. Thereby it is necessary to do further research and improvement for indoor, especially the structure of laboratory filter equipment. Contents of the invention [0003] One of the purposes of the present invention is to provide a combined exhaust gas filter box to address the above shortcomings, in order to solve the problem that...
