Novel absorption package device

Abstract

A novel absorption package device solves the problems that a traditional gas distribution mass transfer device is large in gas flow resistance, poor in use effect and serious in energy consumption, scaling, blocking and the like are easily generated, and production continuity is affected. The novel absorption package device comprises a spraying device and a dewatering device which are arranged an absorption tower body. The novel absorption package device is characterized in that a first spraying layer, a second spraying layer and a third spraying layer of the spraying device are supported on the middle of a frame, the spraying device is provided with a spraying main pipe and a spraying branch pipe, primary dewatering blades are arranged in a primary blade supporting frame of a primary dewatering layer of the dewatering device, secondary dewatering blades are arranged in a secondary blade supporting frame of a secondary dewatering layer, reverse flushing layers are arranged above and below the primary dewatering layer and the secondary dewatering layer and comprise a plurality of reverse flushing water pipes with reverse flushing spraying nozzles. The novel absorption package device is reasonable in design, compact in structure, small in system resistance, high in mass transfer efficiency and defogging efficiency, good in desulfurization effect, convenient to maintain and stable to run, and scaling and blocking are not easily generated.

Description

technical field [0001] The invention belongs to the technical field of flue gas mass transfer devices for desulfurization towers, and specifically relates to a device with low pressure drop, high mass transfer efficiency, no scaling and blockage, good desulfurization effect, high demisting efficiency, convenient maintenance, and can ensure continuous and reliable desulfurization towers. The new absorption package in operation. Background technique [0002] Most of the exhaust gas desulfurization devices of thermal power plants, thermal heating companies, cement plants, chemical plants and enterprise-owned power plants are desulfurization absorption towers, which contain mass transfer devices such as grilles, bubbles, and liquid separation columns. Gas separation and mass transfer devices usually include: packing devices, porous plate structures, sieve plates, grids, bubble structures, etc. These traditional gas separation and mass transfer devices have complex structures, c...

AI Technical Summary

Problems solved by technology

These traditional gas separation and mass transfer devices have complex structures, cumbersome manufacturing processes, large resistance to gas flow, a great impact on the overall pressure drop of the desulfurization system, and poor use effects; moreover, the requirements for the output power of the induced draft fan are increased, and serious consumption energy

[0003] In addition, as the operating time of desulfurization and defogging devices in power plants and thermal heating companies increases, dehydration efficiency often decreases, defogging elements deform, fall off, and even blades are damaged; resulting in scaling, clogging, etc.

The pressure difference on both sides of the dehydration device continues to increase, resulting in an increase in the moisture content of the discharged net flue gas, which affects the desulfurization effect of the desulfurization tower

When this happens, the production equipment needs to be shut down to flush the dehydration device, which seriously affects the continuity of production and poses a safety hazard

Moreover, the dehydration device in the prior art has defects in layout structure, demisting effect and daily maintenance, etc.
