Dust removing and ventilating device of cement processing plant

Abstract

A dust removing and ventilating device of cement processing plant comprises a ventilation shell, the front end of the ventilation shell is sealed, the rear end of the ventilation shell is opened, a first partition plate and a second partition plate are arranged in the ventilation shell and divide the interior of the ventilation shell into a buffer cavity, a dedusting cavity, and a draught fan installation cavity; the circumferential lateral wall of the bottom of the dedusting cavity is provided with an opening, which is covered by a baffle plate; a draught fan is installed in the draught fan installation cavity; an air inlet pipe is arranged on the front end surface of the ventilation shell, the downstream end of the air inlet pipe is communicated with the buffer cavity; a connection pipe is arranged on the second partition plate and is communicated with the dedusting cavity and the draught fan installation cavity; multiple through holes are evenly arranged along the circumference of the first partition plate; inclined guide pipes are arranged on the first partition plate, the upstream ends of the guide pipes are communicated with the buffer cavity, the downstream ends point to the circumferential lateral wall of the dedusting cavity and are in the dedusting cavity; and a dust baffling plate that extends along the axial direction is arranged on the bottom of the dedusting cavity. The provided dust removing and ventilating device has the advantages that the structure is simple, the dedusting efficiency is high, and the accumulated ash can be conveniently cleaned.

Description

technical field [0001] The invention relates to the field of cement processing, in particular to a dust removal ventilation device for a cement processing plant. Background technique [0002] The cement processing industry produces a large amount of fine dust in the process of producing cement. The dust floating in the air of the processing plant will cause serious damage to the respiratory system of the workers. It is necessary to use a ventilation device to pump the dust out of the plant. The ventilation device currently used has a simple structure, and directly draws the air carrying dust out of the factory building. Over time, it will cause serious dust pollution to the environment outside the factory building. There are also ventilation devices with additional filters. During the process, the filter screen is used to filter the dust in the air, and the filtered air dust meets the emission standard. However, after this type of ventilation device is used for a long time, ...

Problems solved by technology

The ventilation device currently used has a simple structure, and directly draws the air carrying dust out of the factory building. Over time, it will cause serious dust pollution to the environment outside the factory building. There are also ventilation devices with additional filters. During the process, the filter screen is used to filter the dust in the air, and the filtered air dust meets the emission standard. However, after this type of ventilation device is used for a long time, the dust gradually gathers on the filter screen and blocks the filter holes of the filter screen, resulting in the failure of the ventilation device. The exhaust effect becomes worse, the filter needs to be replaced frequently, and the use cost is high
