Abstract
The utility model relates to a spray device arranged in a desulfurizing tower. The spray device comprises a spray branch pipe and a nozzle, wherein the spray branch pipe is connected with a nozzle short joint, and the nozzle short joint is connected with the nozzle through two 45-degree bends in reverse dislocation butt joint. The spray device is improved aiming at the problems of scaling and plugging of the spray pipe and the nozzle, improves the connection mode of the spray branch pipe and the nozzle, and is provided with the hollow cone nozzle not apt to be plugged at the tail end. In desulfurizing system operation, when a certain spray layer is needed to be stopped due to low load, slurry in the pipe flows to the outside of the nozzle along the pipe lowering slope of the spray pipe, plugging of the nozzle and the spray branch pipe caused by the fact that slurry remains in a horizontal pipe can be avoided, and the problems of scaling and plugging from the spray branch pipe to a nozzle outlet are solved. Use ratio of a desulfurizing system is improved, accordingly environment benefit is improved, and a large amount of maintenance and environment protection expanse is saved for enterprises.
Description
Technical field
The utility model relates to spray equipment in a kind of desulfurizing tower, be applicable to the system with desulfurizing agents such as lime, calcium carbonate, or derivatives thereofs (battery slag, white clay, yellow mud etc.), belong to boiler smoke Wet Flue Gas Desulfurization Technique environmental technology field.
Background technology
Along with the develop rapidly of China's economic, problem of environmental pollution is on the rise.The Energy Mix of China is take coal as main, and its consumption increases day by day, SO
2Discharge capacity also constantly increase, China is atmospheric environment SO in the world
2One of a few countries of severe contamination.Therefore ecological environment suffers that serious destruction also causes very large economic loss.Coal accounts for about 71% in the primary energy of China, and from now within considerable time the consumption of primary energy still take coal as main.Coal in all parts of the country all contains chemical composition " sulphur " to some extent, yet the coal of the overwhelming majority just directly enters Industrial Stoves, Industrial Boiler internal combustion, the SO that burning produces without processing
2Directly be discharged into again in the atmosphere etc. harmful substance, China is discharged into the SO of atmosphere every year
2Have 1800 ~ 2,000 ten thousand tons, wherein 80% from combustion process, so cut down SO
2Discharge capacity, prevent atmosphere SO
2Pollute, become China and reached now one of following main social problems in quite over a long time.
Sulfur method mainly contains at present: 1, physical desulfurization method 2, chemical desulfurization method 3, biological desulphurization method;
Desulfur technology mainly contains: desulfurization after desulfurization 3 in 1, desulfurization 2 before the burning, the burning, the burning.
Operation technique is the most extensive at present, and the rear desulfur technology of still burning that effect is best, typical technology has limestone/gypsum method, alkaline process, two alkaline process, ammonia process, seawater wet method, spray drying process, electronic beam method, ammonia process etc., wherein the most widely used be comparatively stablize, the lime-gypsum method desulfur technology of technology comparative maturity.
In wet method lime-gypsum method and derivative thereof (battery slag, white clay, the yellow mud etc.) desulfur technology, the most scabrous is exactly internal system pipeline scale blockage problem, at present comparatively reliably technology is being arranged aspect the circulation liquid pool fouling precipitation.But also there be not comparatively basic breakthrough aspect solution spray piping and the spray nozzle encrustation obstruction.
The installation form of spraying layer nozzle mainly contains following several (seeing Fig. 1-3) at present; its main deficiency is in the time of need to stopping certain layer of spraying layer when system loading is low; the slurries of pipe interior are deposited in spray supervisor, arm and the nozzle arm; can cause for a long time the obstruction of spray piping nozzle arm and nozzle; affect its desulfuration efficiency and environmental protection; reduce the utilization rate of system, increased maintenance cost and the environmental protection fund expenditure of equipment.
Summary of the invention
The purpose of this utility model is to overcome the prior art deficiency, and spray equipment in a kind of desulfurizing tower is provided, and has solved the fouling blockage problem from the spray arm to jet expansion.
The technical scheme that the utility model is taked is:
Spray equipment in a kind of desulfurizing tower comprises spray arm, nozzle, and the spray arm links to each other with a nozzle short circuit, and the nozzle short circuit links to each other with nozzle by 45 ° of elbows of two reverse dislocation docking.
The utility model improves for spray piping and spray nozzle encrustation blockage problem, by the type of attachment between improvement spray and the nozzle, and uses endways not susceptible to plugging hollow cone nozzle.In service in desulphurization system, in the time of need to stopping certain one deck spraying layer as hanging down because of load, the slurries of pipe interior can prop up the pipeline descending grade along nozzle and flow to beyond the nozzle, can not cause nozzle and nozzle to prop up blockage in the horizontal pipe because resting on, solve the fouling blockage problem from the spray arm to jet expansion.Make desulphurization system increase utilization rate, thereby improve environmental benefit, for enterprise has saved very most maintenance and environmental protection disbursement.

Fig. 3 is existing spray equipment C-structure figure;
Fig. 4 is the utility model structure chart;
Wherein, 1 is the spray arm, and 2 is nozzle, and 3 is the nozzle short circuit, and 4 is 45 ° of elbows.
The specific embodiment
Further specify below in conjunction with the specific embodiment.
Spray equipment in a kind of desulfurizing tower comprises spray arm 1, nozzle 2, and spray arm 1 links to each other with a nozzle short circuit 3, and nozzle short circuit 3 links to each other with nozzle 2 by 45 ° of elbows 4 of two reverse dislocation docking.
Spray arm 1 links to each other with a nozzle short circuit 3, then be connected to two 45 ° of elbows 4, be connected with nozzle 2 again, the gradient of a decline of 2 formation from spray arm 1 to nozzle, the slurries of pipe interior are flowed out along inner-walls of duct, thereby effectively solved the problem that nozzle and nozzle prop up blockage in the wet desulphurization.
Claims (1)
1. the interior spray equipment of desulfurizing tower comprises spray arm, nozzle, it is characterized in that the spray arm links to each other with a nozzle short circuit, and the nozzle short circuit links to each other with nozzle by 45 ° of elbows of two docking that oppositely misplace.
