Description
Technical field
The utility model relates to a kind of flue gas desulfur device, and specifically a kind of efficient boiler desulfurization treatment system, belongs to flue gas desulfur device field.
Background technology
China is the country of energy resource structure based on fire coal, and atmosphere pollution belongs to coal-burning, and sulfur dioxide a large amount of in flue gas causes serious pollution to air, causes China's acid rain to increase year by year, strictly will control the content of Sulfur Dioxide In The Atmosphere for this reason.In smoke treatment in sulfur dioxide process, spray column is a successfully application, but in application process due to flue gas enter desulfurizing tower after exist in the uneven situation of smoke distribution and tower and there is no the reasons such as mass transfer parts, thus result in the problems such as liquid-gas ratio is large, energy resource consumption is high.
Utility model content
In order to solve the problem, the utility model devises a kind of efficient boiler desulfurization treatment system, and desulfuration efficiency is high, and the pressure loss is lower, dust-removal and desulfurizing, and harmful substance is separated from flue gas, absorbs sedimentation, finally reaches the object of purifying smoke.
The technical solution of the utility model is:
A kind of efficient boiler desulfurization treatment system, comprise tower body, described tower body is provided with spraying layer and enters mouth, divide equally cloth below described spraying layer and be provided with wall stream cylinder, described wall stream cylinder is flared structure, bell-mouthed upper end is fixed on inside the tower wall of described spray desulfurizing tower, described wall stream cylinder circumferentially has some apertures, make distribution of slurry evenly and do not increase equipment resistance, collect and the slurries flowed down along tower wall of reallocating, the slurries flue gas that risen entrainments again, effectively improve the utilization rate of absorbent slurry, the gas-liquid improved near tower wall exchanges, gas/liquid is more evenly distributed, stop is had to the rising flue gas stream near tower wall, polycondensation, air-flow is forced to flow to spray column center, increase gas liquid interfacial area, substantially increase utilization rate and the SO of desulfurizing agent
2removal efficiency, the bottom of described tower body is provided with nozzle, and described nozzle is connected with pulse suspension pump by pipeline, and described pulse suspension pump is connected with desulphurization tower slurry pool, and the spout of nozzle is at the bottom of the tower of described desulfurizing tower.By pulse suspension pump, liquid is extracted out from desulphurization tower slurry pool top, again return in cyclic oxidation pond through slurry pipe line, can pulse be produced when slurries spray from nozzle, rely on this impulse action to have stirred the solid content at the bottom of tower, and then prevent precipitation.
Further, described enter the top of mouth be provided with spiral board, described spiral board comprises blind plate and some swirl vanes, described blind plate is circular configuration, be positioned at the bottom of described spiral board, described swirl vane one end is fixed on the circumferential edges of described blind plate, and the other end is fixed on the tower wall of described tower body, arranges in rotation twist formula.Boiler smoke tangentially enters tower body by the bottom of tower, guide effect due to column plate blade rotates rises, drop is by air-flow driven rotary, produce contacting with each other between centrifugal force strengthening flow, the flue gas with centrifugal force through rotating enters spraying layer, distribute very uniformly because flue gas cross section with centrifugal force and in tower defines, good condition is provided for raising desulfuration efficiency.
The utility model fume desulfurizing tower is the visual plant in boiler plant, is equipment boiler gas being carried out to desulfurization process.That a kind of desulfuration efficiency is high, the desulphurization plant of the pressure loss lower double energy dedusting, desulfurizing tower uses cyclone technique, fluidics, pressure atomization technology and Venturi tube technology, take alkalies as carrier, the harmful substances such as the dirt in flue gas, sulfur dioxide, hydrocarbon are separated from flue gas, absorb sedimentation, finally reach the object of purifying smoke.
Fume desulfurizing tower selects pyramidal structure, and structure is simple, and pressure drop is fallen little, and mass-transfer efficiency is high, is convenient to adopt resistant material manufacture etc.
The utility model has the advantage of: desulfuration efficiency is high, the pressure loss is lower, dust-removal and desulfurizing, and harmful substance is separated from flue gas, absorbs sedimentation, finally reaches the object of purifying smoke.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
