Abstract

The invention discloses a process system for treating toxic and harmful tail gas by a dry type chemical filtering device, and the system comprises a main adsorption system and an auxiliary adsorptionsystem; the main adsorption system is used for enabling the process waste gas to pass through an inlet, an inlet pipeline, an automatic control valve, a quick connector, a manual cut-off valve and a main adsorption barrel in sequence for filtering; the automatic control valve is fixedly connected with one side of the quick connector, the other side of the quick connector is fixedly connected withone side of the manual cut-off valve, the other side of the manual cut-off valve is connected with the inlet end of the main adsorption barrel, and process waste gas enters an outlet pipeline throughthe outlet end of the main adsorption barrel after being filtered by the main adsorption barrel. The outlet pipeline is sequentially connected with a manual cut-off valve, a quick connecting hoop, a concentration detection port and an automatic cut-off valve. By means of the design, safety and reliability can be guaranteed in the replacement process of the adsorption barrel, and the risk that untreated toxic and harmful waste gas escapes in the replacement process is avoided.

Description

Technical field[0001]The present invention relates to the field of process exhaust gas treatment, and more particularly to a process system for treating toxic and harmful exhaust gas in a dry chemical filtration device.Background technique[0002]The usual adsorbent bucket is disposed with an import and export valve. During the actual use, this common adsorbent is not suitable for treating toxic hazardous gases, such as arsenanes. After the adsorbent in the bucket consumes, it is necessary to use a bucket that has a new adsorbent to consume a complete adsorbent bucket. During the replacement, partially unprocessed toxic exhaust gas is residuous due to the pipe. It will lead to security incidents.[0003]At the same time, during the replacement process, if there is no spare adsorption bucket, stop is required to replace it. Effects of continuous production of normal processes.[0004]Due to the longevity problem of the adsorbent, it is necessary to replace it in time. Conventional adsorpti...
