A kind of harmful gas filter equipment for chemical industry and pharmacy with partial pressure filter

Abstract

The invention discloses a chemical and pharmaceutical harmful gas filtering device with partial pressure filtering, which comprises a tank body, a bracket, a dirt outlet, an air inlet pipe, a partial pressure air filter device, a barometer, a movable cover, and an adjusting knob. Beneficial effects: by splitting the air flow and installing it for filtering, it is possible to avoid the gas injection in the tank due to the instantaneous pressure of the gas in the tank, which will lead to the phenomenon of thin wall at this position under long-term action, resulting in rust and rust. Under the action of the components of the rust itself, the rust and the harmful gas undergo a chemical reaction again, and the dirt on the inner wall of the tank is removed through the rotary scraping mechanism, so as to avoid the part of the gas inside the tank that cannot be treated by activated carbon and the dirt. Gas-solid reaction, and at the same time, under the action of the wall slag structure, the dirt scraped and dropped by the rotary scraping mechanism is further processed, so as to ensure the normal use of the air filter of the equipment and reduce the wear and tear on the equipment filter.

Description

technical field [0001] The invention relates to the technical field of chemical and pharmaceutical filtration, more precisely, it is a harmful gas filtering equipment for chemical and pharmaceutical with partial pressure filtration. Background technique [0002] With the gradual improvement of my country's medical industry, the field of pharmaceutical technology has also been gradually improved, and because the chemical pharmaceutical is produced by a variety of chemicals or bacteria in the production process, a large amount of waste will be produced in the workshop. Therefore, in order to ensure the safety of pharmaceutical personnel, filter equipment for harmful gases is usually installed in the workshop to filter the air. [0003] However, because the harmful gas produced during the pharmaceutical process is continuous, after the gas is introduced through the intake pipe, the circulation pressure of the return gas is relatively high, so it is directly directed at the tank ...

Problems solved by technology

[0003] However, because the harmful gas produced during the pharmaceutical process is continuous, after the gas is introduced through the intake pipe, the circulation pressure of the return gas is relatively high, so it is directly directed at the tank body for input. Under long-term effects, the inner wall of the tank Due to the direct impact of the harmful gas, the wall pipe appears thinner, causing a small amount of rust on this part, and at the same time, under the action of the rust's own components, it will react chemically with the harmful gas, resulting in new gas and At the same time, while the harmful gas is being filtered inside the tank, the filtered impurities are easily trapped on the inner wall of the tank under the action of air pressure, resulting in a large amount of impurities appearing on the inner wall of the tank. Under the action, it will affect the work of the equipment,
