Problems solved by technology

[0002] At present, in domestic engineering practice, especially in projects for utilizing flue gas waste heat, the flue gas is generally first passed through the dust collector to reduce dust, and then enters the heat exchanger to exchange heat to generate steam. The dust collector and heat exchanger are set separately. Not only the system is complicated, but also occupies a large area, which increases the investment cost

Abstract

The invention relates to an integrated fume dustfall stem superheater, and belongs to the mechanical equipment, comprising shell, deposition chamber, tube bundle, tube bundle channel, traverse baffle, safety valve and steam temperature regulating valve. A fume inlet and a fume outlet are arranged on the shell, the shell is provided with a heat exchange screen comprising tube bundle, and two ends of tube bundle passing through the shell are connected with the opposite tube bundle channel, respectively. The traverse baffle is positioned in the shell, steam inlet pipeline and steam outlet pipeline are arranged on the opposite tube bundle channel, respectively. The safety valve and the steam temperature regulating valve are mounted on the tube bundle channel of steam outlet pipeline. The structure of the device can be vertical type, horizontal type or slanting type. The device has advantages of fume dustfall and steam superheating effects, simple structure, convenient installation and disassembly, safe and reliable operation, wear resistance, long service time, small space, low investment cost, etc.

Description

technical field [0001] The invention relates to an integrated flue gas and dust-reducing steam superheating device, which belongs to the category of mechanical equipment. Background technique [0002] At present, in domestic engineering practice, especially in projects for utilizing flue gas waste heat, the flue gas is generally first passed through the dust collector to reduce dust, and then enters the heat exchanger to exchange heat to generate steam. The dust collector and heat exchanger are set separately. Not only the system is complicated, but also occupies a large area, which increases the investment cost. Contents of the invention [0003] In view of the above existing problems, the purpose of the present invention is to provide an integrated flue gas dust reduction steam superheating device that can simultaneously perform superheating of flue gas dust reduction steam, which not only achieves the effect of flue gas dust removal, but also meets the heat exchange req...
