Problems solved by technology

[0002] At present, large-scale pharmaceutical industrial parks adopt centralized heating, which can provide stable and reliable high-grade heat sources and save energy; however, some areas still need to use coal-fired boilers to provide heat sources, and coal will generate a lot of dust and dust after burning in the boilers. Sulfur dioxide, dust with a particle size of less than 10 μm falls to the ground very slowly, especially dust with a particle size of less than 0.1 μm can float in the sky all year round and is called "floating dust"; "floating dust" contains various toxic metal particles, such as being inhaled by people After the lungs, it will cause various respiratory diseases and seriously endanger people's health

Embodiment 1

[0045] A wet boiler flue gas desulfurization and dust removal device, comprising a body 1, an air inlet pipe 2, a gas collecting hood 3, an air outlet pipe 4, a sewage pipe 5, a spray device 6, a demisting device 7, and a liquid feeding pipe 13. The body 1 One side of the lower part is provided with a bottom plate 8, and one side of the upper part of the bottom plate 8 is provided with an air inlet pipe 2, one end of the air inlet pipe 2 extends into the interior of the body 1, and the other end is connected with the gas pipeline; the lower side of the interior of the body 1 is provided with a washing liquid , and the gas outlet of the intake pipe 2 is located inside the water washing liquid, the boiler flue gas enters the interior of the body 1 through the air intake pipe 2, and desulfurization and dust removal are carried out through the water washing liquid to remove most of the dust in the flue gas and neutralize part of the sulfur dioxide;

[0046] The inner side of the bo...

Embodiment 2

[0057] The difference from Example 1 is that: the inner side of the gas collecting hood 3 is provided with a packing layer 12, and the packing layer 12 is an activated carbon packing layer. The discharge of washing liquid; on the other hand, it can absorb the peculiar smell in the flue gas and protect the environment.

Embodiment 3

[0059] The difference from Example 1 is that an air distribution plate 9 is provided on the inner side of the body 1, and a number of air distribution holes are provided on the air distribution plate 9. The uniformity of flue gas distribution inside the body 1 is improved, thereby enhancing the desulfurization and dust removal effect of flue gas.

Abstract

The invention discloses a wet type boiler flue gas desulfurization and dust removal device. A bottom plate is arranged on one side of the lower part of a body, a gas feeding pipe is arranged on one side of the upper part of the bottom plate, washing liquid is arranged on the lower side in the body, a gas outlet of the gas feeding pipe is arranged in the washing liquid, a spray device is arranged on one side in the body, a defogging device is arranged on one side of the upper part of the spray device, a gas gathering hood is arranged on one side of the upper part of the body, the gas gatheringhood is in a reversed funnel shape, a gas discharging pipe is arranged on one side of the upper part of the gas gathering hood, a liquid feeding pipe is arranged on one side of the lower part of the body, a sewage draining pipe is arranged on one side of the liquid feeding pipe, and valves are arranged on the liquid feeding pipe and the sewage draining pipe. According to the wet type boiler flue gas desulfurization and dust removal device disclosed by the invention, a circular turnable type defogging device is utilized to change the flue gas flowing direction continuously, so that flue gas canstrike a defogging plate for multiple times, the washing liquid carried in the flue gas can be removed, the washing liquid is prevented from being drained out along with the flue gas, and environmental pollution is avoided; meanwhile, waste of the washing liquid is reduced.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment, in particular to a wet boiler flue gas desulfurization and dust removal device. Background technique [0002] At present, large-scale pharmaceutical industrial parks adopt centralized heating, which can provide stable and reliable high-grade heat sources and save energy; however, some areas still need to use coal-fired boilers to provide heat sources, and coal will generate a lot of dust and dust after burning in the boilers. Sulfur dioxide, dust with a particle size of less than 10 μm falls to the ground very slowly, especially dust with a particle size of less than 0.1 μm can float in the sky all year round and is called "floating dust"; "floating dust" contains various toxic metal particles, such as being inhaled by people After the lungs, it will cause various respiratory diseases and seriously endanger people's health; while sulfur dioxide meets the water vapor in ...
