Abstract
A cyclone dust collector with a reflecting screen device consists of a spiral pipeline, a clamp plate and a reflecting screen. An air inlet is connected with the spiral pipeline, the clamp plate is arranged on the spiral pipeline, an exhaust pipe is arranged in the center of the clamp plate, a lower spiral portion of the spiral pipeline is sealed by the clamp plate, the other portion of the spiral pipeline is connected with a lower cylinder, a cone is arranged below the cylinder, the reflecting screen is arranged below the center of a cone lining, a suction hole is arranged on the reflecting screen, and four legs distributed below the reflecting screen are respectively connected with a cone shell. The reflecting screen arranged on the cyclone dust collector prevents rising purified air from whirling dust away, abrasion of the exhaust and end heat exchanger equipment is reduced, service life of the equipment is prolonged, gas output of a gas stove is increased by 5%, and accordingly electricity utilization is saved and environmental protection requirements are met.
Description
Technical field: the utility model relates to deduster, particularly relates to a kind of cyclone dust collectors that have the radiation shield device.
Background technology: in present coal gas chemical industry, the inefficiency of cyclone dust collectors, resistance is big, and dust is many, and discharging can not reach national requirements for environmental protection.It is a difficult problem that troubles the coal gas chemical industry always.Calculate according to theory, the cyclone dust collectors gas velocity is fast more, and efficiency of dust collection is high more; And gas burner requires coal gas to require gas-flow resistance the smaller the better by cyclone dust collectors the time, like this can voluminous coal gas.Press the cyclone dust collectors designing requirement, dusty gas separates effective depth and generally will reach about 11.5 meters, add ash discharge, normal height will reach about 15 meters, but the coal gas chemical industry is subjected to the gas burner limitation in height, the highest can only have 12 meters, so the dedusting of cyclone dust collectors highly is controlled, so efficiency of dust collection is low.
Summary of the invention: the purpose of this utility model is exactly that a kind of cyclone dust collectors that have the radiation shield device will be provided, it can overcome the existing existing above problem of cyclone dust collectors, the purpose of this utility model is to realize like this, the cyclone dust collectors that have the radiation shield device, be made up of helical pipe, clamping plate, radiation shield, it is characterized in that: air inlet connects with helical pipe, and the top of helical pipe is provided with clamping plate, the central authorities of clamping plate are provided with blast pipe, and are supported by reinforcement; Helical pipe below spiral part is sealed by clamping plate, and remainder connects with the below cylinder, and the cylinder below is provided with cone, and described cylinder is made up of cylinder liner, shell, and described cone is made up of cone liner, shell; The central authorities below of described cone liner is provided with radiation shield, and described radiation shield top is provided with suction hole, and uniform four pin in below connect with conoidal Shell respectively.After the utility model is provided with radiation shield, can make separated dust fall into ash bucket along the annular space between cone liner and the radiation shield.Having prevented effectively that the Purge gas that rises from rolling dust again takes away, and has destroyed the tornado effect in the grey storehouse effectively, has reduced taking out of of control of dust material.Reduced wearing and tearing, prolonged the service life of equipment blast pipe, road, back heat exchange equipment.Purified dedusting gas.Reduce the load of latter equipment aeration tower, saved water resource.The gas forming amount that has improved gas burner reaches more than 5%, has saved power consumption.The coal dust that dedusting is got off can utilize once more, has reached environmental requirement.On reduction gas-flow resistance and raising dusty gas separative efficiency, reached design effect.

The specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing;
The cyclone dust collectors that have the radiation shield device, be made up of helical pipe 9, clamping plate 10, radiation shield 12, it is characterized in that: air inlet 14 connects with helical pipe 9, and the top of helical pipe 9 is provided with clamping plate 10, the central authorities of clamping plate 10 are provided with blast pipe 8, and are supported by reinforcement 11; Helical pipe 9 below spiral parts are by clamping plate 10 sealings, and remainder connects with the below cylinder, and the cylinder below is provided with cone, and described cylinder is made up of cylinder liner 7, shell 5, and described cone is made up of cone liner 6, shell 5; The central authorities below of described cone liner 6 is provided with radiation shield 12, and described radiation shield 12 tops are provided with suction hole, and uniform four pin in below connect with conoidal Shell respectively.During concrete enforcement, radiation shield is made by stainless steel, and helical pipe, cylinder liner, cone liner are made by cast iron, and other parts are made by steel plate.The gap that cylinder liner, cone liner and outer cover of steel plate form, gap that forms between clamping plate two steel plates and ash storehouse, below cylinder inner wall are poured into a mould with refractory concrete.Air inlet, clamping plate and helical pipe Bolt Connection, all the other methods with welding connect, described radiation shield lower end four pin and conical Shell welding, all weld by NB/T47003.1-2009[steel welding non-pressure vessel] make, check.It is two-layer that device housings is coated with red lead.Operating process is that dusty gas is entered through helical pipe by air inlet pipe with certain speed, to become circular motion by rectilinear motion, the dusty gas overwhelming majority of rotation is downward twist from cylinder along inwall, move towards the cone direction, dusty gas produces centrifugal force in rotary course, the grit of density greater than gas got rid of to inwall, and grit is in case contact with inwall, just lose inertia force and fall, enter Hui Cang at the effect lower edge of self gravitation inwall.Most of gas is subjected to the effect of radiation shield, rotation is risen and is discharged through blast pipe, fraction gas enters Hui Cang with the annular space of dust between radiation shield and cone, the gas velocity that enters grey storehouse reduces, dust is trapped in the grey storehouse, and the fraction gas then suction hole through the radiation shield top is sucked into the blast pipe discharge.
