Low-energy-consumption hybrid white smoke elimination device

Abstract

The invention discloses a low-energy-consumption hybrid white smoke elimination device, which comprises a mixing tower, wherein three openings are formed in the mixing tower; two of the openings are air inlets and are respectively connected with a multiple layered dehydration guide device of chimney exhaust gas and a belt cooler exhaust gas conveying device; the other opening is an air outlet and is directly connected with outside air; the multiple layered dehydration guide device of chimney exhaust gas comprises a T-joint and a dehydration tower, a dehydration elbow and an draught fan which are connected with the T-joint in sequence; the air outlet of the draught fan is connected on the mixing tower through a pipeline; the belt cooler exhaust gas conveying device comprises a belt cooler; a chimney is arranged on the belt cooler; a smoke hood is arranged at the top end of the chimney and is connected with the mixing tower through a pipeline. According to the low-energy-consumption hybrid white smoke elimination device, not only is the installation and maintenance cost of the device reduced, but also is the operation cost of the device reduced; the treatment effect of white smoke is greatly improved.

Description

technical field [0001] The invention relates to a chimney white smoke elimination device, in particular to a low energy consumption hybrid white smoke elimination device used at the chimney. Background technique [0002] The flue gas discharged from the chimney is in a saturated state. When the external ambient temperature is low, the water vapor condensed under the influence of low temperature will turn into a white plume, forming the phenomenon of "white smoke" from the chimney, while "white smoke" "It will have a great impact on the surrounding environment and nearby equipment, which is not conducive to the normal use of the equipment, will greatly shorten the service life of the equipment, increase the maintenance frequency of the equipment and the cost of operation and maintenance. At present, the technical methods to eliminate "white smoke" mainly include condensation heat transfer method, self-smoke heat transfer (GGH) method, steam heating method (flue gas reheater),...

AI Technical Summary

Problems solved by technology

[0003] 1. Large investment: Due to the use of large equipment such as heat exchangers and condensers, the investment in equipment to eliminate "white smoke" will reach 600,000 to 700,000 yuan / m 3 Flue gas volume, the total investment is generally as high as 10-20 million yuan

[0004] 2. High energy consumption: the device needs to consume electricity, gas or steam, and the general energy consumption cost is about 4 to 7 yuan / m 3 , the operating cost of the gas direct heating method can even be as high as 30 yuan / m 3

[0005] 3. Equipment maintenance is difficult and expensive: because "white smoke" often contains corrosive substances soluble in water, the equipment is easily corroded by it during use, and it is easy to cause leakage after the equipment is corroded, and then Frequent maintenance of equipment is required, which greatly increases the cost of equipment operation

[0006] 4. The effect of eliminating "white smoke" is not complete: some equipment can only reduce part of the "white smoke". "
