Description

High-efficiency vacuum wet dust collector

Technical field

The utility model relates to a kind of high-efficiency vacuum wet dust collector.

Background technology

Hydrofilter taking water as dedusting medium at present, be broadly divided into spray type dust separator, water film type duster and moisture film and spray the compound type dust remover combining, the deduster of this several types, in actual use all degree different to exist dedusting not thorough, the problems such as exhaust emissions exceeds standard, its reason is that ash-laden gas can not contact with water cmpletely.In order to address the above problem, Chinese patent CN100386133C discloses a kind of water-bath type dust cleaner, comprise housing, mounted thereto bucket and the turning barrel of leading, insert in housing one end of smoke guide barrel, the other end is provided with vortex type side and enters mouth, have main shaft in smoke guide barrel top center position and stretch out hole, main shaft is protruding by stretching out hole, and the bearing block of bearing by being located at smoke guide barrel top center position is fixed, be installed on it to turning barrel and main shaft through transport, one end is positioned at smoke guide barrel, the other end is stretched out by smoke guide barrel, the one end that is positioned at smoke guide barrel is provided with helical runner, external part is provided with support, have in the water following outstanding smoke guide barrel part of sunkening cord the circular hole being evenly distributed.When actual use, motor drives turning barrel High Rotation Speed in smoke guide barrel by the belt pulley that is located at spindle top, first ash-laden gas enters shower room by entering mouth under the impeller of turning barrel and the effect in circular hole district, ash-laden gas is carried out first dedusting by the shower nozzle that is located at shower room top, then be pressed into the bottom of turning barrel, again after circular hole district secondary pressurized, being intensive minute bubbles enters in bathroom by force, minute bubbles are by obtaining bathing purifying dedusting from the process that floats to smoke evacuation chamber in the water of bathroom, dirty dirt is recycled water and is expelled to settling tank through blowoff valve, flue gas after purification is constantly discharged through smoke evacuation chamber and exhaust opening.This water-bath type dust cleaner has the features such as dust removal efficiency is high, energy-conservation, noise is low, but exists following problem: (1) is located in housing because leading bucket, turning barrel, helical runner etc., in the time breaking down, is not easy to very much maintenance; (2), because water in dust removal medium is to deposit in bathroom, along with the prolongation of bathing time, worse and worse, dust removing effects worse and worse, has affected the stability of discharge index to water quality; (3) in the time that the indoor dirty dirt of dust discharge deposits to a certain degree, need to open blowoff valve by artificial timing and be expelled to settling tank, operation inconvenience, has also increased operating cost; (4) in the time of the dirty dirt of discharge, because water in dust removal medium is also discharged from simultaneously, therefore, within this period, can not carry out dedusting to ash-laden gas.

Summary of the invention

In order to solve the problem of above-mentioned existence, the utility model aims to provide the high-efficiency vacuum wet dust collector that a kind of efficiency of dust collection is higher, effect is more stable, operation maintenance is convenient, automatic operating degree is high.

The technical scheme that the utility model adopts is: a kind of high-efficiency vacuum wet dust collector, comprises housing, overflow pipe, enter mouth, outlet flue, sedimentation basin, dust flue, dust discharge chamber, water inlet pipe, the water inlet of overflow pipe is located in housing, delivery port is connected with dust flue, the big up and small down cone in dust discharge chamber, be located at the below of housing, one end of dust flue is connected with lower end, dust discharge chamber, the other end is located in sedimentation basin, and the water inlet of water inlet pipe is located in sedimentation basin, delivery port is located at the top in housing, central authorities are provided with suction pump, it is characterized in that: also comprise smoke exhaust pipe, air exhauster, dividing plate, automatic spacing water compensation mechanism, timing smoothing machine, one end and the outlet flue of smoke exhaust pipe are fixedly connected, central authorities are provided with air exhauster, and dividing plate is fixedly arranged on the top of central authorities in housing, and housing top is divided into into smoke-box, go out smoke-box, described housing enters smoke-box, the indoor smoke deflector that is provided with of smoke, is provided with central authorities and is uniformly distributed foraminate flue gas shunting plate below smoke deflector and between dust discharge chamber, described enter mouth, outlet flue is located at respectively into smoke-box, go out the top of smoke-box, automatic spacing water compensation mechanism is located at sedimentation basin final stage appropriate location, and timing smoothing machine is located at sedimentation basin chopped-off head appropriate location.

Described housing enters smoke-box, go out smoke-box can also be respectively equipped with water inlet pipe delivery port, and is positioned at the water inlet top of overflow pipe.

Described water inlet pipe delivery port can also be provided with at least cross section flat cuboid nozzle triangular in shape of one deck.

Described air exhauster can be speed governing type.

The beneficial effects of the utility model are: (1) water in dust removal medium drains into sedimentation basin in the lump by dust discharge chamber and dirty dirt, having reached water in dust removal medium is flow regime, after to ash-laden gas bathing, can be because of the prolongation along with the bathing time, water quality and changing, ensure dedusting effect self-consistentency, thereby realized the stability of discharge index; (2) because not being provided with any works in housing, there will not be fault; (3) dirty dirt, with water in dust removal media discharge to sedimentation basin, does not need manual operation, has reduced operating cost yet; (4) because establishing automatic spacing water compensation mechanism, timing smoothing machine, having realized the utility model does not need personnel on duty, can automatic operating, and operation maintenance is convenient; (5) because housing enters smoke-box, the indoor smoke deflector that is also provided with of smoke, increase the path of ash-laden gas bathing, improved the efficiency of dedusting; (6) under negative pressure, enter water in dust removal medium for ash-laden gas and can form the bubble of different sizes, in these bubbles, may accompany dust-laden particle, can not complete the emission problem by the bathing of water in dust removal medium, the utility model is uniformly distributed foraminate flue gas shunting plate in being provided with below smoke deflector and between dust discharge chamber, bubble can be broken, guarantee the abundant bathing of dust-laden particle, thereby further improved efficiency of dust collection; (7), because be also provided with at least cross section flat cuboid nozzle triangular in shape of one deck at water inlet pipe delivery port, the further bathing to ash-laden gas, has also just further improved the efficiency of dedusting, has also improved the stability of effect; (8) exhausting motor is made as speed governing type, carries out speed governing with the difference of ash-laden gas flow, more energy-conservation; (9), because water in dust removal medium is flow regime, both made, at high-temperature dust-containing flue gas applications the utility model, also can get a desired effect.
