Abstract

The wet-typed efficient dust collector of the utility model relates to gas cleaning technique, which is suitable for various industrial furnaces and kilns. The existing wet-typed high energy venturi dust collectors have the disadvantages that energy consumption is high, the quantity of the waste water which is produced by the existing wet-typed high energy venturi dust collectors is large, and the secondary pollution is caused. The utility model comprises two dust collecting chambers and a dewatering chamber, wherein, the dust collecting chambers are provided with gas nozzles, jet heads and gas inlets with nozzles. Because of the double theories of condensing coalescence and impact washing, the utility model which is made from non-corrosive, antiwear and temperature-resistant materials has the advantages that the applicable range of the particle diameter is wide, the dust collecting rate is high, no waste water is exhausted, the investment is low, the operation is reliable, the expense is low and the service life is long.

Description

Wet-type, efficient dust collector

The utility model relates to flue gases purification, is a kind of Wet-type high-efficient deduster, is applicable to multiple industrial furnace gas cleaning.

The deduster that is used for the industrial furnace gas cleaning in the prior art is divided into four big classes such as machinery, filtration, static, wet type traditionally, and this four classes deduster respectively has different characteristics and performance, however the shortcoming that exists some to be difficult to overcome to some extent again.For example mechanical shortcoming is that efficiency of dust collection is not high, generally is used for the processing of giving of stove; Filter collector efficient height, but cost of equipment height, operating cost is also high, and is not suitable for the gas cleaning of high temperature (more than 150 ℃); The efficiency of dust collection height of electrostatic precipitator, but apparatus expensive, the operational management complexity; The high energy venturi scrubber efficiency of dust collection height of wet type, but the energy consumption height produces a large amount of washes simultaneously, causes secondary pollution, must be if waste water will be recycled again through purifying.

Above-mentioned defective in view of the prior art existence, the purpose of this utility model is to provide a kind of Wet-type high-efficient deduster, utilize the condensation coalescence---impact the dual principle of washing, adopt new version and corrosion resistant, heatproof, wear-resisting material to make, it is wide to be suitable for particle size range, the efficiency of seizing dust height, not effluent, reduced investment, reliable expense are low, long service life, blower fan are not with water, are a kind of desirable Wet-type high-efficient dust arresters, can be widely used in all types of industries stove, adopt the primary dust removing scheme to be up to state standards.

External form of the present utility model is a cuboid, and its structure mainly is made up of two dirt pockets ［ I, II ］ and a dewatering station ［ III ］.Establish air jet pipe (2) in the dirt pocket ［ I ］, the lower end of air jet pipe (2) is provided with jet thrust (3), and a nozzle (1) is installed in the air inlet appropriate location; Dirt pocket ［ II ］ left upper portion communicates with dirt pocket ［ I ］, establishes air jet pipe (6) in it, and the lower end of air jet pipe (6) is provided with jet thrust (7), and nozzle (5) is installed on the top of air jet pipe (6); Dewatering station's ［ III ］ left upper portion and dirt pocket ［ II ］ communicate, in dewatering station's ［ III ］, be provided with big baffle plate (8) near dirt pocket ［ II ］ side, big baffle plate (8) lower right side is equipped with an inertia dehydrator (9), and a wire mesh dehydrator (10) is installed on top; For preventing that air-flow from entering dewatering station's ［ III ］ together with the spray that is evoked, be provided with polylith small front apron (4) in the right side partition top of dirt pocket ［ I ］, ［ II ］; Plaster outlet pond (12) is established in the outside, deduster bottom, and appropriate location, top, pond is provided with water level adjustment hole (11).

During the utility model uses, ash-laden gas enters the air jet pipe (2) of dirt pocket ［ I ］ through blast pipe, the water smoke that nozzle (1) produces makes some stick to that the fine dust coalescence becomes big dust particle on the water droplet to the coalescence effect of dust, when dust flows to down by jet thrust (3) with the wind, air velocity is accelerated, the high speed dust-contained airflow pours the water around jet thrust (3), the water surface that forms certain depth acutely rolls, dust is captured the flue gas of handling through one-level by water body and enters dirt pocket ［ II ］ again after same processing procedure, greatly improved the arresting efficiency of deduster to particle dust, thereby guarantee that deduster outlet flue gas reaches national specified discharge standard, after gas behind the two-step purification enters dewatering station's ［ III ］, air velocity reduces, utilize gravitational settling, mechanism such as inertial separation are through big baffle plate (8), the water smoke that inertia dehydrator (9) and wire mesh dehydrator (10) can make air-flow carry afterwards removes, and is not with water and operate as normal to guarantee blower fan.

The utility model utilizes the heat balance principle, and the strict control shower nozzle water yield makes flue gas heat that water smoke is all evaporated, and reaching non-wastewater discharge, thereby avoids secondary pollution.The heavy ash in deduster bottom enters plaster outlet pond along ramped bottom surface, can adopt artificial or scraper plate machine, and underflow pump etc. are removed plaster.

At problems such as industrial furnace flue gas corrosion, wearing and tearing, high temperature, housing of the present utility model and internals all adopt domestic resourceful granite processing, granite has good wear-resisting, and corrosion resistant, heat resistance can guarantee that the deduster life-span reached more than 20 years.The inertia dehydrator adopts steel plate processing back to adopt good anticorrosive paint to handle; Wire mesh dehydrator adopts stainless steel wire processing.

Through evidence, the utility model is used for six tons of steel-smelting electric furnace dedustings, and its efficiency of dust collection can reach more than 98%, and exhanst gas outlet concentration is lower than 150 milligrams/mark rice ³, resistance is less than 1500Pa, and no waste water is discharged, and investment has only 1/3rd of sack cleaner, and reliable, expense is low.

Compared with the prior art, the utility model is reasonable in design, structure advanced person, the efficiency of dust collection height, cost of equipment is low, non-wastewater discharge, do not produce secondary pollution, simple and convenient management, reliable, operating cost is low, cost is low, durable in use, be applicable to the gas cleaning of all types of industries stove, have good economy, society and environmental benefit.
