Abstract

The utility model provides a dust remover which is composed of a whirlwind barrel, an exhaust pipe, a dust hopper, an inlet, an outlet and an elbow. The utility model is characterized in that the whirlwind barrel is divided into a big and a small stages, the two-stage whirlwind barrel adopts a serial structure; the exhaust pipe is arranged in the whirlwind barrel, and a helical flow deflector is arranged on the exhaust pipe. The dust remover can remove the dust by stage, and the flow deflector is arranged on the exhaust pipe of the whirlwind barrel to cause the device to generate larger centrifugal force and have better dust removing effect. Compared with the dust remover of the same size, the dust removing efficiency of the dust remover is raised by 10 to 20%, and the volume of the dust remover is reduced; particularly, the utility model has much better smoke and dust removing effect on a magnesia vertical kiln.

Description

A kind of deduster

Affiliated field

The utility model belongs to cleaner.

Background technology

At present, existing smoke eliminator adopts various forms of dedusters to carry out dedusting, wherein in cyclone dust collector, have singly revolve, bispin, four is revolved, six form such as revolve, they are that industrial smoke is assigned to each whirlwind tube, the multiprocessing air quantity is big more more for specification whirlwind tube of the same race, but the efficient of dedusting does not have variation, can not reach the effect of classification dedusting, these dedusters are with low content of technology, and dust removing effects does not reach the technical indicator of national existing standard regulation.

Summary of the invention

The purpose of this utility model provides a kind of novel deduster, and it adopts two group bispin whirlwind tubes and flow deflector, to solve the problem that existing deduster exists.

The purpose of this utility model is to realize like this, it is made up of whirlwind tube, blast pipe, dust hopper, inlet, outlet, elbow, it is characterized in that: the whirlwind tube divides large and small two-stage, adopt cascaded structure between the two stage cyclone tube, in the whirlwind tube blast pipe is housed, on blast pipe, add flow deflector, guide vane the blast pipe external spiral around.

Concrete structure of the present utility model adds dust cap in the cone below the whirlwind tube in addition.Its dust cap one or two.

Advantage of the present utility model and effect are that it one is can the classification dedusting, in the willy-willy tube is primary dust removing, remove the flue dust of larger particles, in the whirly tube, remove flue dust than granule, the 2nd, the dress guide vane makes it produce bigger centrifugal force on the blast pipe in the whirlwind tube, and dust removing effects is better.The deduster efficiency of dust collection of its comparable same specification improves 10%～20%, can also reduce the volume of deduster, is better to the smoke medicining dust-removing effect of magnesia shaft furnace by it.

The specific embodiment

Below in conjunction with accompanying drawing an embodiment of the present utility model is elaborated.

Shown in Fig. 1,2,3,4, the utility model is made up of whirlwind tube 3, blast pipe 2, dust hopper 4, inlet 5, outlet 1, elbow 6, air inlet 5 is positioned in the middle of the blast pipe 2, top is air outlet 1, its feature is: the whirlwind tube divides willy-willy tube 3, whirly tube 8 two-stages, the first order is connected in parallel by two equal willy-willy tubes and forms, the second level is connected in parallel by two equal whirly tubes and forms, adopt cascaded structure between the two stage cyclone tube, the whirlwind tube is fixed on the laying dust bucket 4.In the large and small whirlwind tube blast pipe 2 is housed, on blast pipe 2, adds flow deflector 7, guide vane 7 blast pipe 2 external spirals around.

As shown in Figure 1, the utility model is for preventing the dust reentrainment of dust, and the cone bottom Nei Jia dust cap 9 below whirlwind tube 3 prevents that the dust secondary from kicking up.Its dust cap 9 can according to circumstances be installed one or two, and the outer rim of guide vane 7 and barrel 3 are fixing.

The course of work of the present utility model is such, dusty gas 5 enters through guide vane 7 and enters two in parallel whirlwind tubes 3 from entering the mouth, dust is separated from gas, fall in the dust hopper 4 along the cone inner surface, gas through primary dust removing enters elbow 6 from blast pipe 2 through exporting 1, enters the next stage dedusting again, and gas is in guide vane 7 is gone into two whirly tubes 8, carry out final dusting, tiny dust falls in the laying dust bucket 4 through the gap between dust cap and barrel.Clean gas enters air-introduced machine through air exit 11 and discharges.

Claims (3)

1 one kinds of dedusters, form by whirlwind tube (3), blast pipe (2), dust hopper (4) inlet (5), outlet (1), elbow (6), it is characterized in that: the whirlwind tube divides large and small two-stage, adopt cascaded structure between the two stage cyclone tube, blast pipe (2) is housed in the whirlwind tube, on blast pipe (2), add flow deflector (7), guide vane (7) blast pipe (2) external spiral around.

2 a kind of dedusters according to claim 1 is characterized in that: add dust cap (9) in the cone below whirlwind tube (3).

3 a kind of dedusters according to claim 1 and 2 is characterized in that: adding dust cap (9) in the described cone below whirlwind tube (3) is two.
