Environment-friendly dedusting device for cement plant

Abstract

The invention belongs to the technical field of dust removal, and particularly relates to an environment-friendly dust removal device for a cement plant, which comprises a shell, a filter cartridge, afan and a controller; wherein the shell is in a tank shape, openings are formed in the upper end and the lower end of the shell, and supporting legs are further fixedly connected to the lower end ofthe shell. The filter cartridge is located in the shell, the filter cartridge is in an annular cylinder shape, the upper end and the lower end of the filter cartridge are fixedly connected to the inner wall of the shell through three-jaw plates, and the lower end of the filter cartridge is fixedly connected with a sealing cover; the center of the sealing cover is fixedly connected with a pipe rod;the pipe rod is located in the filter cartridge, the two ends of the pipe rod are sealed, and air holes are formed in the outer wall of the pipe rod. According to the environment-friendly dust removal device for the cement plant, air flow impacts the inner wall of the filter cartridge through the air pump, and a second motor drives a scraper to scrape the outer wall of the filter cartridge, so that the cleaning function of the filter cartridge in the environment-friendly dust removal device is achieved, the filtering effect of the filter cartridge is guaranteed, and the practicability of theenvironment-friendly dust removal device for the cement plant is improved.

Description

technical field [0001] The invention belongs to the technical field of dust removal, and in particular relates to an environment-friendly dust removal device for a cement plant. Background technique [0002] The cement industry is the main source of industrial dust in my country. The dust emission is about 2% to 3% of its output. The total emission in the country exceeds 10 million tons. Long-term exposure of the human body to cement dust can easily cause various diseases, and cement dust will cause The land is alkalized, which seriously pollutes the environment. During the cement production process, whether it is crushing, drying or grinding, calcination will generate a lot of dust. Since each process is a dry operation, it has formed many dust spots and large areas , The characteristics of a wide range, and the waste gas at the end of the cement kiln accounted for about 60% of the waste gas of the entire cement production line, of which the waste gas at the kiln tail account...

AI Technical Summary

Problems solved by technology

The generation of dust not only pollutes the environment, but also poses a serious threat to the respiratory health of operators. Operators must wear dust masks to operate normally, but it will also affect their health, and the environment is too dusty, reducing visibility, and staff The operation is very inconvenient and affects environmental protection; the existing dust removal device in the cement plant often uses a bag filter. After the bag filter has been used for a period of time, the internal filter will be blocked by dust, and the staff will clean the filter. Due to the lack of existing technology, The cleaning effect of the filter screen is poor, and dust remains inside the filter screen, which affects the re-use effect of the filter screen inside the dust collector.

[0003] There are also some technical solutions about environmental protection dedusting devices for cement plants in the prior art. For example, a Chinese patent with application number CN201720022250.4 discloses a new type of dedusting equipment for cement plants, including air intake pipes, filter screens, vibrators, Dust collection box, water baffle, dust removal chamber, fender, silt discharge port, nozzle, water eliminator, exhaust pipe, induced draft fan, filter, water storage tank; filter the concentration of cement plant by setting a filter in the intake pipe Higher dust, and the dust in the filter screen falls into the dust collection box through the vibration of the vibrator, and the collected dust can be used as raw materials for the cement plant; using wet dust removal, the gas passing through the filter screen is in the dust removal room It is thoroughly purified, and then discharged from the equipment through the water eliminator and the induced draft fan; it has the advantages of strong reliability and low environmental impact; The vibration effect of the vibrator on the dust in the filter screen is low, so that the dust inside the filter screen cannot fall off through vibration, which affects the filtering effect of the filter screen, thereby causing the limitations of this technical solution
