Air treatment device

Abstract

The invention discloses an air treatment device, and aims to solve the technical problem that no tail end purification equipment capable of dredging dangerous medium gas in emergency is provided in the prior art. One end of a gas collection chamber is connected with an upstream unit, the other end is connected with a downstream unit, and gas is guided from the upstream unit to the downstream unit through a fan; a power part transmits transmission power to a speed regulation assembly through a transmission assembly to change the rotating speed of the fan, so that the fan can obtain at least two rotating speed states; and a state guiding assembly is used for driving the speed adjusting assembly to act so that the fan can obtain two rotating speed states. According to the technical scheme, the requirement for purifying and guiding gas of a process unit or a plant unit in the prior art can be effectively met, and the air treatment device has the advantages of being rapid in disposal and high in safety.

Description

technical field [0001] The invention relates to air treatment technology, in particular to an air treatment device. Background technique [0002] It is well known that industrial sites carry out air flow through the air supply mechanism. Commonly, the air supply mechanism uses a combination of a fan and a filter to form a terminal purification device powered by itself. The custom of s±10% is sent out evenly. [0003] For example, the application publication number is CN110566519A, and the invention patent application titled "A Fan Filter Unit" includes a housing, a DC motor, blades, a HEPA filter device and a controller, and a mounting bracket is arranged on the outer side of the top of the housing. The housing is a detachable upper part and a lower part, the upper part has a convex strip, the lower part has a groove corresponding to the convex strip, the top of the housing is provided with an air inlet and the air inlet is arranged in the center of the top, A controller i...

AI Technical Summary

Problems solved by technology

[0004] Obviously, in order to cope with different ventilation requirements, it is necessary to control the air supply speed of the air supply mechanism. In view of this problem, as a solution, many air supply mechanisms are arranged in the prior art. By starting different numbers of air supply mechanisms To realize the adjustment of the air supply rate, as another solution, a variable frequency motor is arranged for the fan as the driving mechanism. However, the guidance equipment using the frequency conversion control to guide the downstream is often slow to take effect, and the time required for the variable frequency working frequency of the variable frequency fan to increase Generally, it takes 10-15min to work at higher power

[0005] In summary, the disadvantages of the prior art are that either there is waste in many air supply mechanisms, or the speed regulation is slow
