A kind of assembled moving bed adsorbent equipment
The utility model belongs to environmental technology field, is related to activated coke dry method flue gas Pollutant Control Technology, and in particular to
A kind of assembled moving bed adsorbent equipment, has cross-flow and convection adsorption effect concurrently, it is adaptable to while processing contains a variety of dirts
The flue gas of thing is contaminated, the integrated purifying of the multiple pollutants such as sulphur, nitre, dioxin, mercury and dust is realized.
Activated coke dry method flue gas Pollutant Control Technology, it is possible to achieve desulfurization denitration demercuration is dust removal integrated, can also be removed
SO3, eliminate white cigarette.The technology does not consume water substantially, saves great lot of water resources, desulfuration byproduct is high concentration SO2, it is easy to resource
Change and utilize, this is the fairly obvious flue gas pollutant control technology of new generation of an advantage.Burnt in steel, metallurgy, electric power, rubbish
The multiple fields such as burning have great application prospect.
Activated coke dry method flue gas pollutant removing main processes are that flue gas is adsorbed by activated coke adsorbent equipment
Qualified discharge after purification, is made up of three parts, and one is the adsorption reaction Tower System for removing harmful substance, and two be that regeneration activity is burnt
Tower System is regenerated, three be the activated coke conveyor system that activated coke loopy moving between adsorption reaction tower and regenerator is used.
The technical process need to configure booster fan, be purified pending flue gas feeding activated coke mobile layer after boosting, activated coke is again
The high-concentration sulfur dioxide gas separated when raw enters byproduct recovery process device, is recovered as sulfuric acid or gypsum etc. valuable
Activated coke dry method flue gas pollutant removing technology, key factor is the adsorption capacity of adsorption reaction, and adsorption capacity
Height depend on the burnt absorption property of adsorbent activity, disposable dress Jiao amount of adsorbent equipment, activated coke in adsorption tower
Contact-sorption time of holdup time, flue gas to be clean and activated coke etc..
Fig. 1 and Fig. 2 are respectively the relation in activated coke and flow of flue gas direction in the prior art.Flue gas is from activated coke in Fig. 1
The side of moving direction passes through activated coke, and this is cross-flow；Flue gas passes through activated coke from the opposite of activated coke moving direction in Fig. 2,
This is convection current.Cross-flow and convection current have respective shortcoming：(1) in cross-flow equipment, flue gas and activated coke time of contact are short, absorption effect
Rate is relatively low；(2) in convection apparatus, flue gas intake resistance is larger.
The content of the invention

There is smoke inlet, smoke inlet is using gradual-enlargement type structure and provided with shutter, and exhanst gas outlet uses microwell plate structure.
Further, moving bed main body is cuboid.
Further, three are provided with the moving bed main body with sieve plate active coke bin spaced apart from each other is isolated, centre is
Main active coke bin, both sides are the active coke bin in side, and shutter and microwell plate structure are on the outer wall of the active coke bin in side.
Further, the gradual-enlargement type structure is exported to activated coke Way in flaring from activated coke.This design feature
The flowing diffusion for coordinating shutter to contribute to flue gas to enter after moving bed adsorbent equipment, when increasing the contact with activated coke
Between, meanwhile, adsorbent activity Jiao in moving bed is difficult to leak from smoke inlet.
Further, moving bed main body is from top to bottom divided into exhanst gas outlet section, flue gas adsorption section, smoke inlet section.
Further, the exhanst gas outlet section width is less than flue gas adsorption section.So, formed on the outside of microwell plate for dropping
Flue gas discharges the cushion space of resistance after low purification, and the cushion space is also convenient for connecting with the smoke discharging pipe located at smoke outlet
The beneficial effects of the utility model：
1st, isolation sieve plate activated coke spaced apart from each other is used provided with multiple in the moving bed adsorbent equipment that the utility model is provided
Storehouse, each activity coke bin uses single batcher discharge, and batcher is by VFC, and speed is adjustable, and each active coke bin is all
The holdup time of activated coke can be set respectively and the optimal holdup time can be set according to flue gas condition；
2nd, the moving bed adsorbent equipment that the utility model is provided has cross-flow and convection adsorption effect concurrently, overcomes prior art
Middle cross-flow, the deficiency of convection apparatus, can improve flue gas and Contact-sorption time of the activated coke in adsorption tower, cigarette can be reduced again
Gas intake resistance, improves purification efficiency.
