Abstract

The utility model relates to a device for eliminating smoke and removing dust which makes gas contact liquid and uses water as dust removing medium. The water inside the device for eliminating smoke and removing dust is in rotary flowing state, so the gas can contact the liquid sufficiently in order to achieve good dust removing effect. The smoke and the dust are not easy to form deposition inside the container of the liquid. The device for eliminating smoke and removing dust is suitable to be used for removing smoke and dust in flue gas.

Description

Rotational flow type eliminate smoke and dust catcher

The utility model belongs to dust arrester, is specially adapted to the dedusting of flue gas.

The device that general water is the smoke abatement and dust control medium is that dried chamber (9) and hydroecium (6) are in deduster inside together, separates with baffle plate (8).The known manner of dedusting is: water inlet pipe (5) is contained in hydroecium (6) top, and air inlet pipe (1) is contained in hydroecium (6) bottom, and the delivery port after the dedusting is contained in the bottom of hydroecium (6); Water is sprayed from top to bottom, and dust enters from below, counter current contacting.Perhaps air inlet pipe (1) is contained in the top of hydroecium (6), and dust is injected in the surface of static water, and dust can not fully contact with water like this, easily with dust deposition the device in.Inflow is during greater than water yield; Cause blower unit band water, inflow is during less than water yield, delivery port place suck air.

The purpose of this utility model is to set up a kind of dust arrester that gas-liquid is fully contacted.

This device for abatement of smoke and dust: the lowest part of hydroecium (6) side is equipped with water inlet pipe (5), water inlet pipe (5) is spent less than 60 with the horizontal angle of cut of hydroecium (6) side, air inlet pipe (1) is equipped with at the top of hydroecium (6), and the difference in height between air inlet pipe (1) end opening and overflow pipe (3) water inlet is greater than the water column height of blower unit suction static pressure power.The water side of overflow pipe (3) links to each other with siphon pipe (2).Blast pipe is connected on the side lower part of dried chamber (9).

During device for abatement of smoke and dust work, its water enters from the bottom tangent of hydroecium (6) side, make water in hydroecium (6), turn round and round, dust is injected on the water surface of eddy flow, the height of crossing overflow pipe (3) water inlet when the water level of hydroecium (6) is greater than deduster hydroecium (6) negative pressure water column when high, the water that has flue dust is discharged automatically by the siphonage of siphon pipe (2), do not cause the water level unlimited upside, and cause blower unit band water, because the effect of air inducing negative pressure, when draining stops draining during to a certain position.Water in the overflow pipe (3) plays the fluid-tight effect, and isolated outside air enters deduster inside; This moment, water level rose again, circulated once more.Can regulate inflow at any time according to dust removing effects,, reach best dust removing effects with control unit interval draining number of times.Compare with existing device for abatement of smoke and dust, the utility model gas-liquid full contact, good dedusting effect, and flue dust is difficult for being deposited in the container.

Accompanying drawing is the embodiment of the utility model on one ton of boiler.

Air-introduced machine suction static pressure power is 400 millimeters of water, height between the end opening of air inlet pipe (1) and overflow pipe (3) water inlet is 400 millimeters, the horizontal angle of cut in side that the side bottom of hydroecium (6) is equipped with water inlet pipe (5) water inlet pipe (5) and hydroecium (6) is on the 30 degree water inlet pipes (5) control valve (4) to be housed, hydroecium (6) side is equipped with overflow pipe (3), overflow pipe (3) water side links to each other with siphon pipe (2), and blast pipe (7) connects blower unit.

Claims

1, a kind of gas-liquid contact is with the device for abatement of smoke and dust of water as the dedusting medium.Plate washer (8) vertically is contained in deduster inside, and deduster is divided into dried chamber (9) and hydroecium (6) two parts.The lowest part of hydroecium (6) side that is characterised in that of the present utility model is equipped with water inlet pipe (5), the horizontal angle of cut of water inlet pipe (5) and hydroecium (6) side is less than 60 °, water inlet pipe (5) is equipped with control valve (4), overflow pipe (3) is equipped with in the side of hydroecium (6), and overflow pipe (3) water side links to each other with siphon pipe (2).

2, device for abatement of smoke and dust according to claim 1 is characterized in that difference in height between air inlet pipe (1) end opening and overflow pipe (3) water inlet is greater than the water column height of blower unit suction static pressure power.
