Embodiment Construction

[0018] Below in conjunction with accompanying drawing, the present invention will be further described as follows:

[0019] as attached figure 1 As shown, the present invention comprises: inlet smoke chamber 9, floating bed heat exchanger 6, outlet smoke chamber 5, dust reduction chamber 4 and dust reduction filter pool 1, inlet smoke chamber 9, floating bed heat exchanger 6, outlet smoke chamber 5 , the dust-suppression chamber 4 and the dust-suppression filter tank 1 are connected sequentially from top to bottom, and a floating bed generator 8 is installed in the inlet smoke chamber 9. The floating bed generator 8 can be a variety of structures such as a nozzle or a rotary cup. The generator 8 is connected to the dust-reducing filter tank 1 through a pipeline, and the dust-reducing filter tank 1 is filled with water, and the upper end of the dust-reducing filter tank 1 is connected to the water supply pipe, and the pipeline between the floating bed generator 8 and the dust-r...

Abstract

The invention relates to the technical field of waste heat recovery, in particular to an energy-saving, dust-settling and emission-reducing device of a condensing fluidizedbed, and the device comprises an inlet smoke box (9), a fluidizedbed heat exchanger (6), an outlet smoke box (5), a dust settling chamber (4) and a dust settling filtration pool (1) which are connected in sequence from top to bottom; a fluidizedbed generator (8) is arranged in the inlet smoke box (9); the pipeline of the fluidizedbed generator (8) is connected with the dust settling filtration pool (1); water is contained in the dust settling filtration pool (1); a fluidizedbed water injection pump (2) is arranged between the fluidizedbed generator (8) and the dust settling filtration pool (1); a fluidizedbed (7) is generated below the fluidizedbed generator (8) in the inlet smoke box (9); the fluidizedbed heat exchanger (6) is arranged below the fluidizedbed (7); the side surface of the dust settling chamber (4) is provided with a gas outlet (14) which is connected with a gas-liquid separator (10). According to the energy-saving, dust-settling and emission-reducing device of the condensing fluidizedbed, not only can heat be exchanged, but also dust, sulfide, nitric oxide and other hazardous substances in flue gas can be absorbed, so that the purposes of saving energy, settling dust and reducing emission are achieved.

Description

[technical field] [0001] The invention relates to the technical field of waste heat recovery, in particular to a condensing floating bed energy-saving, dust-reducing and emission-reducing device. [Background technique] [0002] In energy equipment, most of them use burning fuel to obtain energy, such as industrial boilers, blast furnaces in steel mills, annealing furnaces, lime calciners, cement kilns, glass kilns, etc. Among these devices, flue gas emission is the main source of heat loss and pollution, and the higher the discharge temperature, the greater the heat loss. In the exhausted flue gas, there is not only the moisture contained in the fuel, but also the smoke and dust, the combustion product CO 2 , SO 2 , NO x and H 2 O. In order to prevent steam condensation and corrosion, the flue gas discharge temperature is generally above 100°C. At this time, the steam will not condense and become superheated. The sensible heat and latent heat of the steam will enter the...
