Abstract
The utility model discloses a treatment device for desulfuration waste liquid, particularly a treatment device for sodium salt-containing desulfuration waste liquid in the coking industry, which solves the problems of environmental pollution, equipment corrosion and influence on coke quality as the desulfuration waste liquid is discharged to the outside currently along with high cost of flue gas desulfurization operation of power plants. The treatment device comprises a coal gas desulfurization tower, a circulation groove, a coke oven gas desulfurization device formed by a reproduction tower, a flue gas desulfurization tower, a sedimentation basin, a raw stock pool and a power plant flue gas desulfurization device formed by a raw stock pump; a distribution branch pipe is connected to a pipeline between a waste liquid inlet of the coal gas desulfurization tower and a waste liquid outlet of a reproduction tower; and the other end of the distribution branch pipe is communicated with the raw stock pool. The alkali source of the power plant can be supplemented on one hand, and on the other hand, the reaction between the secondary salt and SO2 in the desulfuration liquid of a coking plant can be saved, thereby improving the desulfuration efficiency of the original power plant. Through the utility model, the waste treatment is realized by using waste, harmless treatment of the waste liquid is achieved, the problem of environmental pollution caused by discharge of desulfuration waste liquid is solved, the resources are saved and reasonable utilization of the resources is realized.
Description
Technical field
The utility model relates to a kind of desulfurization waste liquor treating apparatus, is specially the treating apparatus that a kind of coking industry contains the sodium salt desulfurization waste liquor.
Background technology
At present, during the coke oven gas desulfurization of the big-and-middle-sized coking industry of China,, great majority adopt wet oxidation method sulfur removal technologies, the composite catalyst of tannin extract+vanadium wherein, and soda ash provides alkali source, and air oxidation regeneration is a kind of of wet oxidation method sulfur removal technology.Follow some side reactions to take place in sweetening process, produce a certain amount of secondary salt, main component is Na
2S
2O
3And NaCNS, and after these secondary salts reach finite concentration, can worsen the coal gas desulfurization process, and reduce desulfuration efficiency, cause H in the coal gas
2S exceeds standard.Domestic most of coke-oven plant is not because the cost problem is established desulfurization waste liquor and carried the salt device, and many employings efflux a part of doctor solution and go coal yard to be sprayed onto in the coking coal, and the way of replenishing the new liquid of part configuration again solves the problem of secondary salt excessive concentration.But the waste liquid that effluxes can cause environmental pollution on the one hand, and corrosion is equipped with coal equipment, and sodium ion can cause coke quality and silica brick performance to reduce in the desulfurization waste liquor on the other hand, in addition, free sulphur in the doctor solution is finally got back to system again, and the load of coal gas desulfurization is strengthened, and has increased operating cost.
And that existing most of means of flue gas desulfurization of power plant employings is sodalime double alkali method (Na
2CO
3-Ca (OH)
2), adopt soda ash startup, soda to absorb SO
2, the method for acetylene sludge as recycling needs constantly to replenish alkali source in the process of desulfurization, and production cost is higher.
Summary of the invention
The utility model contains the sodium salt desulfurization waste liquor and adopts the mode of effluxing to have contaminated environment, etching apparatus and influence coke quality in order to solve existing coke-oven plant, the high problem of means of flue gas desulfurization of power plant operating cost proposes the treating apparatus that a kind of coking industry contains the sodium salt desulfurization waste liquor simultaneously.
The utility model is to adopt following technical scheme to realize: coking industry contains the treating apparatus of sodium salt desulfurization waste liquor, comprise by the coal gas desulfurization tower, circulating slot, regenerator connects successively with pipeline and the coke oven gas desulfurization device that constitutes, also comprise by fume desulfurizing tower, sedimentation basin, former stock tank and former stock pump connect successively with pipeline and the means of flue gas desulfurization of power plant device that constitutes, innovative point of the present utility model is to be connected with shunt pipe on the pipeline between waste liquid import of coal gas desulfurization tower and the regenerator waste liquid outlet, and the shunt pipe other end is communicated with the former stock tank of means of flue gas desulfurization of power plant device.
Measuring pump and control valve are housed on the described shunt pipe, are convenient to control the flow that desulphurization waste liquid of coke oven gas enters the means of flue gas desulfurization of power plant waste liquid.
Adopt structural design of the present utility model, the doctor solution that the coke-oven plant is effluxed enters in the means of flue gas desulfurization of power plant liquid, can replenish power plant's alkali source on the one hand, on the other hand can be secondary salt in coke-oven plant's doctor solution and SO
2Reaction is removed, and has improved the desulfuration efficiency of former power plant, realizes the treatment of wastes with processes of wastes against one another and accomplishes the harmless treatment of waste liquid, can kill two birds with one stone, both solve the problem of desulfurization waste liquor discharging environmental pollution, economize on resources again, turn waste into wealth, reached the reasonable resources utilization.Coking industry desulfurization waste liquor (sodium salt waste liquid) is incorporated the technical research of means of flue gas desulfurization of power plant system into, be domestic initiation, favorable economic benefit and economic benefit have been obtained, can solve the coking industry desulfurization waste liquor handles, not only reduced investment but also free from environmental pollution, and the advantage that has an economic benefit, the industrial applications effect is remarkable, has exemplary role preferably, wide popularization and application in the worth same industry at home.
