Background technology
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 Byproduct.
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
The purpose of this utility model is to provide a kind of assembled moving bed adsorbent equipment, has cross-flow concurrently and convection adsorption is imitated Really, to improve flue gas and Contact-sorption time of the activated coke in adsorption tower, while reducing flue gas intake resistance, purification effect is improved Rate.
Above-mentioned purpose is achieved by the following technical solution:
A kind of assembled moving bed adsorbent equipment, including moving bed main body, the upper end of moving bed main body is activated coke entrance, Lower end exports for activated coke, is sieved in the moving bed main body along activated coke entrance to activated coke Way out provided with multiple isolation Moving bed main body is divided into multiple active coke bins by plate, isolation sieve plate;The moving bed body top is provided with exhanst gas outlet, and bottom is set 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 Connect.
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.
Brief description of the drawings
Fig. 1 is that (wherein, A is activated coke entrance to cross-flow devices schematic diagram of the prior art, and B exports for activated coke, and C is Smoke inlet, D is exhanst gas outlet);
Fig. 2 is that (wherein, E is activated coke entrance or exhanst gas outlet to convection device schematic diagram of the prior art, and F is activity Jiao outlet or smoke inlet);
Fig. 3 is the utility model schematic device (wherein, 1, activated coke entrance;2nd, activated coke is exported;3rd, smoke inlet Section;4th, exhanst gas outlet section;5th, flue gas adsorption section;6th, main active coke bin;7th, the active coke bin in side;8th, the smoke inlet of blind shaped; 9th, microwell plate;10th, sieve plate is isolated;11st, cushion space).
