Steam mixer used for flue gas conditioning system of cement industry

Abstract

A steam mixer used for a flue gas conditioning system of a cement industry comprises a mixed steam gas collection tank (1), a steam and water mixing device (3), a boiler steam inlet valve (4), an industrial water inlet valve (5), a steam outlet valve (6) and a condensate water draining valve (7). The boiler steam inlet valve (4), the industrial water inlet valve (5), the steam outlet valve (6) and the condensate water draining valve (7) are all connected with a single chip microcomputer (8). The mixed steam temperature is automatically adjusted according to feedback, and the pressure is stable; industrial water or steam is fully atomized; the use amount of boiler steam is greatly reduced, the influence on the power generation amount is reduced, and the energy-saving effect is obvious; and equipment mounting is convenient, maintenance is easy, and the service life is long.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to a steam mixer for treating discharges from cement kilns, in particular to a steam mixer for a flue gas conditioning system in the cement industry. Background technique [0002] At present, the overall deterioration of my country's environmental conditions has not been fundamentally curbed, environmental contradictions are prominent, and the pressure continues to increase. Atmospheric smog is prominent in some key areas and cities, and the discharge of major pollutants in many areas exceeds the environmental capacity. The overall situation of air pollution is becoming increasingly severe, and the public’s requirements for environmental quality are constantly increasing, especially the PM2.5 pollution incident that broke out in recent years. , making the voice of speeding up the control of air pollution more and more louder. [0003] In the new Air Pollution Prevention and ...

Problems solved by technology

[0007] The purpose of this invention is to solve the problems of dust removal, emission reduction and environmental management, and propose a brand-new device for intelligent conditioning and tempering of flue gas dust, which can be applied to the dust removal system and can better improve the dust removal effect

The present invention solves the problem of wet bottom and sticky pole wire caused by the lack of humidification tower in the original dust removal device and the use of ordinary water spray humidification from a practical level, and completely changes the use of pipeline steam to affect waste heat power generation and sticky pole wire The backward method not only makes efficient use of waste heat facilities, improves the dust removal effect, but also eliminates the unsafe hidden dangers caused by traditional water spraying, and fundamentally solves the technical bottleneck that the kiln head of the cement production line cannot effectively humidify
