Dedusting and ventilating device for heating and ventilation engineering of building

Abstract

The invention discloses a dedusting and ventilating device for heating and ventilation engineering of a building. The device comprises a cylindrical dedusting cylinder, the top of the dedusting cylinder is in bolted connection with an upper cover, and the upper cover forms an air inlet pipe communicating with the interior of the dedusting cylinder; the bottom of the dedusting cylinder is connected with a bottom cover, and an ash discharge hopper communicating with the interior of the dedusting cylinder is formed in the bottom cover; a reverse blowing pipe is mounted on the side wall of the dedusting cylinder, and an air outlet is formed in one side, opposite to the reverse blowing pipe, of the side wall of the dedusting cylinder; a rotatable installation assembly used for fixing dust filtering cylinders is arranged in the dedusting cylinder, the dust filtering cylinders are distributed on the rotatable installation assembly in an annular array mode in a vertical direction, and a dedusting air channel is formed by the air inlet pipe, the rotatable installation assembly, the dust filtering cylinders and the air outlet. The dedusting and ventilating device can continuously conduct ventilation and dust removal operation, workers can dynamically maintain the dust removal and ventilation device conveniently, and the heating and ventilation requirements of residents are not affected.

Description

technical field [0001] The invention relates to the technical field of ventilation and dust removal, in particular to a dust removal and ventilation device used in building heating and ventilation projects. Background technique [0002] HVAC is an important part of the construction industry, which includes three aspects of heating, ventilation and air conditioning. The ventilation link refers to improving the indoor air environment by means of ventilation. With the continuous improvement of people's living standards, people tend to pursue a higher quality living environment. In order to meet the needs of the public, more and more developers install central air-conditioning in residential buildings, while residents use heating for their homes. For the convenience, also choose the central air conditioner. Due to the large air supply volume of the central air conditioner, it is necessary to install a large air supply unit, and these air supply units are installed outdoors all...

AI Technical Summary

Problems solved by technology

However, when the anti-injection pipe in the existing dust removal device is working, it is necessary to stop the air supply unit from supplying air to the dust removal cylinder, and the anti-injection pipe is started independently to blow off the dust on the filter cartridge

This leads to the inability of the air supply unit to operate continuously, and the dynamic maintenance of the ventilation device cannot be achieved, which seriously affects the living of residents in the community.
