Cement dust collecting system

Abstract

The invention discloses a cement dust collecting system which comprises a cement pit, a ventilating duct, an air collection hood, a cyclone dust collector inlet, a cyclone dust collector, a cyclone dust collector outlet, an ash bucket, an air blower and a chimney, wherein the cement pit is arranged on one side of the cyclone dust collector, and the cement pit is communicated with the air collection hood through the ventilating duct; the air collection hood is arranged at the outlet of the cement pit, and one end of the air collection hood is communicated with the inlet of the cyclone dust collector through the ventilating duct; two sides of the cyclone dust collector are provided with the cyclone dust collector inlet and the cyclone dust collector outlet; the ash bucket is arranged on one end of the cyclone dust collector; the air blower is arranged on one side of the cyclone dust collector and connected with the chimney through the ventilating duct; and the air blower is arranged between the cyclone dust collector and the chimney. The cyclone dust collector can be used for greatly reducing the occupational hazard of cement processing and has the advantages of good dust collection effect, environmental protection and easiness for popularization and use.

Description

technical field [0001] The invention relates to the technical field of application of cement dust removal devices, in particular to a cement dust removal system. 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 exhaust gas at the end of the cement kiln accounted for about 60% of the exhaust gas of the entire cement production line, of which the exhaust gas at the kiln tail accounted for abo...

Problems solved by technology

[0003] Comparative document 1: Chinese patent CN202921115U describes a cement dust removal mechanism, which includes a bellows, a dust removal pipe, a water mist nozzle and a driving motor. The top of the bellows is provided with an air inlet pipe, a water mist nozzle is installed on one side of the bellows, and a drain is opened at the bottom of the bellows. The central part of the bellows is equipped with an interlocking rotating shaft, and fan blades are installed on the interlocking rotating shaft. One end of the interlocking rotating shaft is arranged outside the bellows, and is connected to the drive motor by a belt. The upper part of the bellows is in an arc-shaped structure, and the top of the air intake pipe is provided with a top cover. There are many deficiencies in the mechanism. If there are too many structures on the bellows, the service life of this mechanism will be shortened, the pressure will be small, and the working efficiency will be low.

The current cement dust removal device has high temperature of kiln exhaust gas and large amount of flue gas, which is difficult to clean up. The cyclone dust collector for dust treatment in the lime plant is insufficient. Therefore, a cement dust removal system is proposed to solve the above problems.
