Abstract

The utility model provides a gas induction dust collector, which is matched with boilers to use. One side of a casing is connected with a smoke inlet tube whose end part is communicated with a steam inlet tube, one side of the casing is provided with a settling tank, and an induction device for spraying the steam is positioned in the casing. The utility model has the advantages that the utility model can remove the content of ashes and harmful gases in the smoke, the rate of cleaning out is high, the cost is low, and the consumption of the energy is small.

Description

Gas induction dust-collector

The utility model relates to a kind of boiler dust remover.

The boiler dust remover kind is more, can be divided into cyclone dust collectors, multi-tube dust cleaner and water dust scrubber etc., general dust Ex-all rate is low, and the oxious component in the gas can not be removed, and the cost height, the technological process complexity, the operating cost height, floor space is big, and the waste discharge water yield is big, cause secondary pollution, the operating cost height.

The purpose of this utility model provides a kind of dust and the high gas induced deduster of pernicious gas free rate.

The purpose of this utility model realizes that by following measure a side of deduster housing 2 connects smoke-intake pipe 3, and the top of housing 2 connects smoke exhaust pipe 1, and this pipe is discharged the gas after handling.In housing one side one or two peep holes 7 are arranged, the bottom surface of housing 2 is a hang plate, the low position of this face corresponding shell side plate has through hole 8, there is stillpot 6 the through hole outside, stillpot is connected on the housing outer wall, and reaching lower housing portion during work in this groove has certain water level, slips into this groove precipitation after dust falls into the water, regularly discharge, and overflow water is discharged from the overflow valve 5 of this groove.Make the water level that remains unchanged in the housing.

Be equipped with in housing 2 and induce spray vapour device 14, at the top of smoke-intake pipe 3 and housing 2 coupling parts steam feeding tube 9 is arranged, this pipe passes the smoke-intake pipe inwall, and also tiltable is installed, and the other end of this pipe leads to the Boiler Steam case.There is water inlet pipe 15 at the housing middle part in order to keep the water level in the housing, vapour Hatch Board 10 is arranged at above-mentioned spray vapour device 14 tops of inducing, the bottom of vapour Hatch Board 10 connect be used for dedusting and impel air whirl on induce dish 11 and under induce and coil 12, housing 2 correspondences induce disc portion that guide plate 13 is arranged, and smoke-intake pipe 3 is connected in the vapour storehouse of inducing spray vapour device.

Induce the top vapour Hatch Board 10 of spray vapour device 14 to be the awl dish type, inducing dish 11 cross sections in the connection of its bottom is the serpentine ring flat-plate, induce dish 12 for inducing the cambered surface ring flat-plate of dish 11 bottoms on the correspondence down, with on induce the dish bottom to constitute the annular vent passage in vapour storehouse, under to induce tray bottom be worn-out open form, opening is convenient to the entry of dust precipitation.

Its operation principle is: induce in the vapour storehouse of spraying vapour device 14 from smoke-intake pipe 3 importings from the flue gas that boiler is discharged, steam feeding tube 9 imports steam from smoke-intake pipe 3 ends simultaneously, together enter in the vapour storehouse, air-flow is baffling in the vapour storehouse, part dust and pernicious gas particle increase and avale, then in the last gas passage of inducing dish 11 and inducing dish 12 to form down, outwards derive, wherein through a plurality of cambered surface water conservancy diversion, form the eddy current dedusting, once more by 13 bafflings of the guide plate on the inner walls, discharge along smoke exhaust pipe 1 after the gas purification after the discharge.Dust and pernicious gas are met the steam of eddy current and behind the submerged, are slipped in the stillpot through hang plate 4, regularly remove to get final product, and overflow valve 5 is constantly discharged and is higher than the water of demarcating water level.

Narrate below in conjunction with drawings and Examples.

Fig. 1 is an overall construction drawing.

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is that the AA of Fig. 2 is to cutaway view.

With reference to accompanying drawing is an embodiment of the present utility model, and its structure is as described below.

This deduster Ex-all rate height, the pernicious gas in the flue dust also can be removed, and volume is little, and is handsome in appearance, and it is lower to consume energy.

Claims

1, a kind of gas induced deduster that is used for boiler dusting, a side joint smoke-intake pipe 3 that it is characterized in that its housing 2, the top of housing 2 connects smoke exhaust pipe 1, the one side has peep hole 7, the lower housing portion bottom surface is a hang plate 4, on the low position corresponding shell side plate of hang plate 4 through hole 8 is arranged, the outside of through hole 8 has stillpot 6 to be connected on this outer wall of housing, overflow valve 5 is arranged on the stillpot 6, be equipped with in the inside of housing 2 and induce spray vapour device 14, steam feeding tube 9 is arranged at the top in smoke-intake pipe 3 and housing 2 coupling parts, connect also and pass smoke-intake pipe 3 inwalls, there is water inlet pipe 15 at housing 2 middle parts, described induce spray vapour Hatch Board 10 bottoms, vapour device 14 top to connect to be used for dedusting and air whirl on induce dish 11 and induce down and coil 12, correspondence induces disc portion that guide plate 13 is arranged on the housing 2, and smoke-intake pipe 3 is connected in the vapour storehouse of inducing spray vapour device 14.

2, gas induced deduster according to claim 1, it is characterized in that inducing the top vapour Hatch Board 10 of spray vapour device 14 to be the awl dish type, induce the shape ring flat-plate of dish 11 cross sections in the connection of its underpart for " S ", under induce dish 12 for corresponding cambered surface ring flat-plate, with on induce the dish bottom to constitute the annular vent passage in vapour storehouse, inducing tray bottom down is worn-out open form.
