Abstract

The invention relates to a special negative pressure ventilation system for production improvement of a cement kiln, and belongs to the technical field of ventilation pipelines. In order to solve the problems that in a traditional negative pressure ventilation system, pipelines are inconvenient to assemble, and the pollution of gas emission is large, the following technical scheme is provided that the air duct comprises a first air duct pipe, a second air duct pipe and a filtering mechanism, a first clamping mechanism is arranged at one end of the first air duct pipe, and a second clamping mechanism is arranged at one end of the second air duct pipe; and a clamping mechanism plate is arranged in the air duct pipe II. Through combination of various structures, when the device is used for assembling a pipeline of a ventilation system, a clamping and fixing mode is used for replacing a traditional screw connection mode, so that the working efficiency of pipeline assembling is improved, and the filtering mechanism is arranged in the pipeline, so that the filtering effect is improved. Therefore, when the cement kiln is subjected to negative pressure ventilation through a pipeline, exhausted air can be filtered and exhausted, pollution to the atmosphere is reduced, the filtering mechanism is fixed in a clamping mode, and the assembling mode is simplified.

Description

technical field [0001] The invention relates to the technical field of ventilation pipes, in particular to a special negative pressure ventilation system for cement kiln production increase. Background technique [0002] Cement rotary kiln belongs to building material equipment and is a kind of lime kiln. Rotary kiln can be divided into cement rotary kiln, metallurgical chemical rotary kiln and lime rotary kiln according to different processing materials. Cement kilns need a good ventilation system during the production process. At present, the assembly of pipelines in the traditional cement kiln negative pressure ventilation system is basically assembled by screw connection. The exchange emission basically adopts the direct emission method, which causes great pollution to the air. [0003] Therefore, how to deal with the ventilation duct is a technical problem that those skilled in the art need to solve at present. Contents of the invention [0004] The object of the ...
