Abstract

The utility model discloses a combined type flue desulfurizing and dust-removing purifier. The sealed purifier body is provided with a water curtain purifying chamber and a filter cloth purifying chamber. A smoke inlet and a smoke outlet are respectively arranged at both ends of the water curtain purifying chamber and the filter cloth purifying chamber. The bottom of the body is provided with a water tank connected between the water curtain purifying chamber and the filter cloth purifying chamber. A liquid desulfurizer is arranged in the water tank. A drain outlet is arranged at the bottom of the water tank. A water pipe which can form a water curtain which flows downwards on the wall is arranged on the wall of the water curtain purifying chamber. Water film sloping plates are interlaced and arranged in the water curtain purifying chamber. A chain type filter cloth circulation mechanism is vertically arranged in the filter cloth purifying chamber. The front end of an air outlet is also provided with a sloping plate type gas-water separator. The water curtain purifying type dust-removing structure and the filter cloth dust-removing structure are organically combined. The smoke abatement, the desulfuration, the dust removal and the deep purification are centralized together. The utility model has reduced volume, strengthened dust-removing effect and decreased cost.

Description

Combined type flue gas desulfurization and dedusting purifier

Technical field:

The utility model relates to a kind of gas cleaning dust arrester, has provided a kind of combined type flue gas desulfurization and dedusting purifier by it, belongs to boiler smoke discharging environmental protection equipment technical field.

Background technology:

At present, it is a lot of to be used for boiler smoke discharging environment protection method equipment, it is more commonly used to abandon method (not considering the recovery of sulphur) with it, be the large-scale environmental protection equipment that control source of atmospheric pollution control acid rain produces, be widely used in coal-burning power plant, smelting, steel rolling, coking, casting and Industrial Stoves, and the smoke gas treatment of city heat supply boiler etc., used cleaner mostly is versions such as cloth bag, water curtain, suspension, volume is big, and dust removal efficiency is lower, is difficult to adapt to the atmosphere environmental requirement in contemporary city.

Summary of the invention:

The utility model discloses a kind of combined type flue gas desulfurization and dedusting purifier, has solved shortcomings such as the big efficiency of dust collection of existing smoke dust-removing equipment volume is low.

Technical solution of the present utility model is as follows: the purifier body of sealing is provided with water curtain clean room and filter cloth clean room, the air inlet mouth and the mouth of giving vent to anger are located at the two ends of water curtain clean room and filter cloth clean room respectively, the bottom of body is tank and sewage draining exit, in the water curtain clean room, also be provided with the staggered moisture film swash plate of putting, the bottom is the desulfurizing agent tank, the wall of water curtain clean room is provided with water pipe can form the water curtain of trickling downwards on wall, flue gas enters behind the waterfall booth under the effect of water curtain, carry out preliminary purification, enter into the filter cloth clean room by tank again, caterpillar chain typec circulation filter cloth vertically is provided with in the filter cloth clean room, the bottom is immersed in the tank, the front end of gas outlet also is provided with the ramp type steam-water separator, after flue gas further filters through filter cloth, discharge by the gas outlet, finish water curtain, filter cloth combined type desulfurization dust separation process.

Good effect of the present utility model is: clean water curtain style dedusting structure is organically combined with the filter cloth dedusting structure, collection smoke elimination, desulfurization, dedusting and deep purifying are one, dwindled equipment volume, strengthened dust removing effects, reduce equipment cost, can be widely used in the device for eliminating smoke and dust of the coal-burning boiler of steam power plant, smelting steel rolling and heat supply sub-district.
