Description
Technical field
The present invention relates to a kind of flue dust desulfurization purifier, relate in particular to a kind of pocket type adsorption desulfurization purifier.
Background technology
Desulfur technology before the pocket type adsorption desulfurization purifier only relates to the pipe-line system injection desulfurization; Utilize sack cleaner to collect that desulfurizing agent, the dust of complete reaction do not return the reaction tower circulation desulfurization in the ash.Its problem is: deduster high concentration inlet, easy fouling of pipeline and corrosion, resistance is big, and power consumption is big, desulfuration efficiency is low, dust collector efficiency is difficult to guarantee, the emission compliance difficulty, and the deduster operation is in overload state, dust-removal and desulfurizing easily lost efficacy, the desulfuration efficiency instability, and exist deduster and duct injection technology to coordinate coupling, the control problem of effective coupling of deduster and circulating ash quantity.
Summary of the invention
The invention provides a kind of pocket type adsorption desulfurization purifier that can improve flue gas desulfurization and dedusting purification treatment effect.
The present invention adopts following technical scheme:
A kind of pocket type adsorption desulfurization purifier comprises the reaction tower device, sack cleaner, the main air blower that are connected successively by pipeline, also is connected with the desulfurizing agent automatic spray apparatus on the sack cleaner.
Described desulfurizing agent automatic spray apparatus comprises the automatic spray tank of desulfurizing agent, spray pipe, the spraying tube connector, automatic regulating valve, automatic blanking machine, the strength dispenser, flow generator, the automatic spray tank of desulfurizing agent passes through spray pipe, the spraying tube connector is connected with the dust collector ash hopper of sack cleaner, the automatic blanking machine of the automatic spray tank of desulfurizing agent is installed in desulfurizing agent jar bottom, and be connected with the strength dispenser, flow generator and spray pipe are installed in strength dispenser two respectively, automatic regulating valve is located in the spraying tube connector, and the spraying tube connector is installed in the middle of spray pipe and the dust collector ash hopper.
Beneficial effect: sulfur-containing smoke gas enters reaction tower among the present invention, and by high-temperature flue gas being carried out air-atomizing, modified, control temperature, activation desulfurizing agent, it is long-pending to enlarge gas, liquid, solid mass transfer contact surface, fully reacts with sulfur dioxide, removes part sulfur dioxide.The sulfur dioxide of the complete reaction sack cleaner that enters adsorption desulfurizing agent does not further carry out desulphurization reaction.Its key technology is: make full use of and bring into play the huge characteristics of sack cleaner filter area and cabinet space, be provided with the automatic sprayer of desulfurizing agent is installed, with desulfurizing agent and the sulfur-bearing flue dust, the droplet that enter sack cleaner collide, absorption and combination reaction.Under external force effects such as inertia force, electrostatic force, difference force, centrifugal force, form a kind of granule, granule plays " medium " effect of sulfur dioxide and desulfurizing agent combination reaction." medium " constantly collided, held back, condensed, and changes from small to big, and forms dust layer at filtering surface, and absorption sulfur dioxide is strengthened and the sulfur dioxide reaction, holds back sulfur dioxide, improves desulfurization degree.And under gravity and deashing effect, fall into the ash bucket case.This process is constantly carried out repeatedly.Because utilized that sack cleaner filter area and cabinet space cause that sulfur dioxide is captured, absorption, chemical combination is very abundant, reached the target of effective purification flue gas.Gas behind the purification filtering is discharged through main air blower, and this is the negative pressure process form; If before main air blower is placed on deduster, then be the malleation form.
Compared with prior art, the present invention has following advantage:
1, use the present invention flue dust is administered, desulfurization degree can reach more than 95%, and dust emission can reach 30mg/Nm
3Below.
2, adopt when of the present invention, bag dust collector can be avoided because of improving desulfurization degree, repeatedly circulates ashes and produces the high concentration inlet, causes the deduster load excessive; The high cost investment problem that can avoid to improve efficiency of dust collection and be brought.
3, utilize the pressure drop of sack cleaner, make desulfurizing agent be adsorbed in the filter bag filtering surface, and utilize dust, desulfurizing agent, droplet at the inertial collision of filter cloth surface and sack cleaner cabinet space, hold back, the multiple action of static, diffusion, cohesion and adhesive force, carry out desulphurization reaction.
4, need not enlarge desulfurization area and facility, directly utilize the filter bag of sack cleaner, carry out desulphurization reaction in large area.
5, the unreacted desulfurizing agent of reaction tower further can be participated in desulphurization reaction in sack cleaner, improve the utilization rate of desulfurizing agent.
6, the automatic sprayer of desulfurizing agent disposes full-automatic batcher, according to the pressure reduction of deduster case chamber, regulates each case chamber spray pipe valve automatically, controls the desulfurizing agent quantity for spray automatically.
7, Pen Tu desulfurizing agent can make influences the reduction of the key factor of desulfurization degree convergence adiabatic saturation temperature, and can increase wet amount, thus the desulfurization degree of reaction tower before improving.
The dust layer controllable thickness of 8, accumulating on the filtrate, and dust layer thickness increases, and can improve desulfurization degree.
9, technology of the present invention is simple, and the reaction tower volume is little, and is not perishable, and whole dedusting setting must not enlarge, and gas cleaning efficient is greatly improved, and investment cost and operating cost reduce, and reaches the purpose of efficient energy-saving.
10, after the operation of this device, non-secondary pollution.
