Abstract

The utility model discloses a centrifugal mechanical washing machine, which is an environment protection machine used for disposing industrial gases and dedusting. The centrifugal mechanical washing machine is interlocked by a rotor with squirrel-cage structure and a stator. The rotor consists of more than two layers of rotor rings(1) fixed on an in-shaft board(7), each ring equipped with a plurality of rotary vanes(2), the in-shaft board fixed on a shaft(5), as well as bearings(6) and shaft glands(10) provided on both ends of the shaft; one end of the shaft is driven by a motor. The stator consists of more than two layers of stator rings(4) fixed on a shell board(11), each ring equipped with a plurality of stator vanes(3), an air inlet(14) and an air outlet(15) provided on both sides of the shell, a flange(8) provided on both sides of the shell and connected with a pipeline, a water spray pipe with a nozzle provided on the machine, as well as water distributors(15) surrounding the water spray pipe. By adopting the machine, the dust content of the gas containing dust is lower than the state environment-friendly gas emission standard after the gas containing dust is disposed. The machine has advantages that the dust removal rate is above 97 percent, the electricity consumption is 80kW to 150 kW lower than the electricity consumption by adopting other methods, the water consumption is half than the water consumption by adopting other wet methods, with good dust removal effect, stable and reliable operation, blocking resistance, less maintenance, which can be widely used for cleaning gases of calcium carbide furnaces, steelmaking furnaces as well as blast furnaces and disposing other industrial tail gases.

Description

The centrifugal mechanical rinsing maching

(1) technical field:

The centrifugal mechanical rinsing maching that the utility model is designed belongs to dust-removal and desulfurizing wash mill in the environmental protection machinery technical field.Be particularly suitable for handling the smoke and dust treatment of various industrial tail gas and dedusting and high temperature, inflammable, explosion hazard gases.

(2) background technology:

The at present domestic industrial tail gas that is used for industries such as chemical industry, metallurgy handles and its kind of dust treatment wash mill of the cleaning recovery of coal gas and furnace of calcium carbide, converter, blast furnace is more, the filter membrane that has that has now developed washs, the wash mill of modes such as Venturi tube is two impacts two water-baths, encircle cyclone type more, liquid curtain spray washing, fluid bed, rapids flushing are washed, fiber grid, dynamic wave, look into according to Chongqing Department of Science and Technology southwest information centre and newly to relate to centrifugal mechanical wash mill of the present utility model, do not find the document and the patent report of same structure at home in the product as yet.

(3) summary of the invention:

The centrifugal mechanical rinsing maching that the utility model is designed, adopt the rotor of mouse cage type structure and stator is staggered is nested with, rotor is made of two-layer above rotor ring, it is some that rotor ring is provided with the rotor blade bar, rotor ring is fixed in the axle on the plate, plate is fixed on the axle by keyway in the axle, and the two ends of axle are provided with bearing and axle envelope, and the air inlet of casing has two imports and flange to be connected with fume pipe; Machine is provided with the sparge pipe of water pipe and band shower nozzle, the water spray tube head is provided with water-locator, the top of casing is provided with handhole cover, one side of casing is provided with two air inlet opposite sides and is provided with an air outlet, when flue dust and water spray enter from the two ends of rotor face, the rotation of driven by motor rotor high-speed, micro dust particle institute when dusty gas and rinsing maching stir blending jointly in the gas is captured, when operation the time be connected centrifugal rinsing maching on the air exhauster rotate at a high speed with the pump up water of blower fan negative pressure with cool off previous cleaning after furnace gas fully mix, water smoke forms face with the absorption of the micronic dust more than the 0.2nm, because centrifugal force and blower fan negative pressure suction effect, constantly break the effect that effective cleaning furnace gas flue dust is played in membrane equilibrium, adopt the utility model to handle dusty gas, content is lower than the national environmental protection atmospheric emission standard behind the dust, dust removal efficiency is more than 97%, compare with other method more than the reduction power consumption 80-150kw, water saving is lacked water consumption 50% than other wet method, processing water recycles, good dedusting effect, be not affected by the external environment, be difficult for stopping up, maintenance capacity is few, it is reliable to operate steadily, small investment, can be widely used in the cleaning recovery and the furnace of calcium carbide of coal gas, converter, the dust treatment of blast furnace etc. also can be used for chemical industry, metallurgy waits the processing of other industrial tail gas.
