Abstract
The utility model discloses a cyclone dust collector, which comprises a shell, and an air inlet and an air outlet formed on the shell. Key points are that: the inner surface of a separating area of the shell is provided with a porous medium material layer; a grooved cooling water channel is formed inside the porous medium material layer; and cooling water leaks from the inside of the porous medium material layer, so that the surface of the porous medium material layer is kept wet. Due to the adoption of the cyclone dust collector, high-temperature dust-containing gas is prevented from damaging a dust collector body structure, and high-temperature particles in gas can be effectively removed; and the cyclone dust collector is particularly suitable for performing explosion-proof dust collection on high-temperature dust-containing coal gas and separating fine particles under a high temperature condition.
Description
Technical field
The utility model relates to a kind of hot precipitator.
Background technology
In chemical industry, oil, metallurgy, electric power and other industry, often produce high temperature dust gas.Because the needs of energy-saving and emission-reduction need high temperature dust gas is carried out dedusting.Under hot conditions, because the high humidity amplitude descends, the cohesion ability of fine particle reduces significantly, and therefore, the separation to fine particle under hot conditions is very difficult.In addition, during high temperature, the equipment material of employing, engineering problems such as version and thermal expansion often influence effective operation of equipment.
Chinese patent document publication number is that the patent of CN 101259453A discloses a kind of high-temperature cyclone dust extractor; Its inner employing is built refractory brick by laying bricks or stones and is inlayed the purpose that abrasion-proof backing block is realized heat resistant and wear resistant; And establish snakelike water cooling tube in bottom ash storehouse and make dust drop to certain temperature, be convenient to the discharge of grieshoch.This patent mainly solves the high-temperature dust removal problem; Rely on refractory brick and inlay the heat resistant and wear resistant damage that abrasion-proof backing block is realized the deduster body; Water cooling tube is arranged on the Hui Cang bottom, and the dust that only deduster has been captured is lowered the temperature, and is similar with the efficiency of dust collection of traditional cyclone dust collectors.
Chinese patent document publication number is that the patent of CN 101559307A discloses a kind of high temperature resistant dust collector that can under 300-1000 ℃ of operating mode, move continuously; Adopt the metal filtration tube to substitute the cloth bag cartridge filter with high temperature resistant; This deduster has efficiency of dust collection height, running resistance and characteristic of low energy consumption; But its metal filtration tube is processed by refractory metal material, costs an arm and a leg, and has increased the cost of deduster greatly.
The utility model content
The purpose of the utility model provides the high resistant to elevated temperatures cyclone dust collectors of a kind of efficiency of dust collection.
To achieve these goals, adopt following technical scheme:
A kind of cyclone dust collectors; Comprise housing and be arranged at air inlet and the gas outlet on the housing; It is characterized in that: the Disengagement zone inner surface of lower housing portion is provided with porous dielectric material layer; Porous dielectric material layer inside has the flute profile cooling water channel, and cooling water oozes out from porous dielectric material layer inside, keeps the moistening of porous dielectric material layer surface.
Too high in order to prevent the deduster skin temperature, reduce the high-temperature gas energy loss, said air inlet, gas outlet and deduster lower inner liner have refractory masses.
In order to prevent that air-flow from evoking the dust in the ash bucket, said deduster bottom is provided with ash discharging hole, is provided with guiding device on the top of ash discharging hole.
Regulate cooling water inflow for ease, the pipeline that connects the grooved cooling water channel is provided with valve.
The utility model can form thin liquid film at the deduster inner surface; Increase humidity in the deduster, improved the cohesion ability of fine particle, effectively suppressed the reentrainment of dust effect; Be beneficial to the capture of dust granule; Make efficiency of dust collection increase substantially, the efficiency of dust collection of traditional cyclone dust collectors is generally 50～60%, and the efficiency of dust collection of the utility model can reach more than 90%; Form thin liquid film at the deduster inner surface simultaneously, can also cool off the high-temperature particle in the dusty gas, when dusty gas is coal gas, can prevent the gas explosion that high-temperature particle causes; In addition, form thin liquid film at the deduster inner surface, can also protect the deduster body not receive the impact of high temperature dust gas, the deduster body is formed effective cooling, last, the utility model does not use refractory metal material, and manufacturing cost is lower.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the profile of A-A among Fig. 1.
Among the figure, part 1 is the gas outlet; Part 2 is a refractory masses; Part 3 is a porous dielectric material layer; Part 4 is the flute profile cooling water channel; Part 5 is a housing; Part 6 is a guiding device; Part 7 is the cooling water system valve; Part 8 is an air inlet; Part 9 is the Disengagement zone; Part 10 is an ash discharging hole; Part 11 is the ash discharging hole valve.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described in detail.
As depicted in figs. 1 and 2, a kind of cyclone dust collectors comprise the housing 5 that is provided with air inlet 8 and gas outlet 1, and wherein air inlet is provided with along the housing tangential, and the gas outlet is positioned on the housing axis, i.e. give vent to anger in tangent line air inlet, center.Porous dielectric material layer 3 is fixed on the housing 5, and porous dielectric material layer 3 is processed with flute profile cooling water channel 4 near housing one side, logical cooling water in the flute profile cooling water channel.Cooling water oozes out from the porous dielectric material layer surface through the capillary force effect, keeps the porous dielectric material layer inner surface to be in moisture state all the time.When cyclone dust collectors when handling high temperature dust gas, gas tangentially enters into deduster inside from air inlet.On the one hand; Under action of centrifugal force; High-temperature solid particle is thrown toward the barrel of cyclone dust collectors, fully contacts with the cooling water on barrel porous dielectric material layer surface, through the evaporation and heat-exchange between high-temperature solid particle and cooling water; Reach the purpose that captures dust granules and reduce the high-temperature particle temperature, conical section enters in the flue-dust retainer particle of capture in gravity effect lower edge; It is inner that the steam of part vaporization gets into cyclone dust collectors, suitable increase the humidity of particle in the flue gas, improved the cohesion ability of fine particle, help the particularly raising of the efficiency of dust collection of fine dust of particle efficiency of dust collection.In this process, can regulate the consumption of cooling water through cooling water system valve 7, prevent that the porous dielectric material layer inner surface from crossing wet or overdrying.On the other hand, the high temperature gas flow after the purification is discharged deduster running into guiding device 6 back rotations upwards through gas outlet 1.
