Abstract

The utility model relates to a sludge drying stench exhaust gas purification device, purifier include cyclone, mixed flow ware, ozone generating device, oxidation reaction tower, active carbon absorption tower, fan, cyclone be connected to the oxidation reaction tower through the mixed flow ware, the oxidation reaction tower be connected to active carbon absorption tower, active carbon absorption tower be connected to the fan. It realizes that the step is: sludge drying stench waste gas is at first through cyclone, will pass through ozone that waste gas and ozone generator behind the cyclone produced and carry together to the oxidation reaction tower and carry out the oxidation reaction, with oxidation reacted gas at active carbon absorption tower internal adsorption waste gas, regenerated carbon, uncontaminated gas is arranged outward through the fan. The utility model discloses to getting rid of of sludge drying stench waste gas is efficient, small, with low costs, the suitability strong, no secondary pollution.

Description

A kind of sludge drying foul waste gas purifier
Technical field
The utility model relates to environmental project waste gas pollution control and treatment field, particularly a kind of sludge drying foul waste gas purifier.
Background technology
Along with the continuous increase of industrial or agricultural and domestic water, China's water technology is also constantly ripe, then creates a large amount of mud, in the disposal process of mud, must carry out drying and other treatment to mud.In sludge drying processing procedure, the organic principle in mud can evaporate together with moisture, thus produces a large amount of high concentration foul waste gas, and it is high that these waste gas have moisture percentage, and the characteristic of temperature more than 200 DEG C, mainly comprises H 2s and NH 3, comprise the foul gas such as multiple aromatic compound, halogenated hydrocarbons, sulfur-containing compound, oxygenatedchemicals in addition.
At present, mud drying process foul waste gas administer adopt primary abatement technology to have: incineration technology, plasma processing techniques, active carbon adsorption technology.Foul waste gas is heated to uniform temperature by the heat that incineration technology mainly utilizes fuel to discharge, make harmful combustible combustion, to reach the object removing harmful substance in waste gas, but sludge drying foul waste gas moisture percentage is high, can not reach the object removing foul waste gas after adopting incineration technology; Plasma processing techniques produces energetic ion by extra electric field, harmful substance in energetic ion and waste gas is efficiently collided, thus removal harmful substance, handled waste gas must be dry, and drying sludge waste gas moisture percentage is high, plasma processing techniques obviously can not meet exhaust emission requirements; Active carbon adsorption technology is that waste gas is passed through adsorbent equipment, active carbon great specific area is utilized to be got off by the noxious substance in waste gas, EGT must remain on below uniform temperature, too high temperature can by the nuisance that adsorbs on the activated carbon from desorption active carbon out, and sludge drying waste gas is generally more than 200 DEG C, active carbon adsorption technology effectively can not adsorb it.Therefore, in the urgent need to finding the effective controlling device effectively can removing sludge drying foul waste gas.
Summary of the invention
The difficult problem that the removal efficiency existed based on existing lignin-sludge mummification foul waste gas is low, the utility model provides that a kind of removal efficiency is high, volume is little, applicability is strong, the sludge drying foul waste gas purifier of non-secondary pollution.
For solving the problem, the technical solution of the utility model is:
A kind of sludge drying foul waste gas purifier, comprises cyclone dust collectors, flow mixing device, ozone generator, oxidation reaction tower, activated carbon adsorber, blower fan; Described cyclone dust collectors left part is provided with exhaust gas inlet, and top is provided with waste gas outlet; Described ozone generator is connected to described oxidation reaction tower, and described cyclone dust collectors are connected to oxidation reaction tower by flow mixing device, and described oxidation reaction tower is connected to activated carbon adsorber, and described activated carbon adsorber is connected to blower fan.
Preferably, described cyclone dust collectors effectively can remove the dust particles in waste gas, to guarantee that follow-up odor removal does not occur clogging.
Preferably, described oxidation reaction tower can malodor molecule in the efficient oxidation degraded sludge drying foul waste gas.
Know-why of the present utility model is, first sludge drying foul waste gas passes into cyclone dust collectors, and due to the effect of centrifugal force, dust particles rotates along cylindrical wall and declines, purified gas is connected to follow-up emission-control equipment by top waste gas outlet, effectively removes the dust particles in waste gas; Subsequently, eliminate the ozone that produces in the sludge drying foul waste gas of dust particles and ozone generator Homogeneous phase mixing be delivered to oxidation reaction tower in flow mixing device, under the strong oxidation of ozone, the deleterious molecular overwhelming majority in foul waste gas is oxidized to CO 2and H 2o, untreated foul waste gas is completely delivered to activated carbon adsorber on a small quantity, is arranged outward completely afterwards by charcoal absorption by blower fan.
The beneficial effects of the utility model are, one, be provided with cyclone dust collectors in odor removal, and effectively remove the dust particles in waste gas, maintain the continuous and steady operation of aftertreatment device; Two, between cyclone dust collectors and activated carbon adsorber, arrange oxidation reaction tower, ozone by most foul waste gas oxidative degradation, can solve the difficult problem that existing sludge drying foul waste gas treatment technology removal efficiency is low.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
In figure, 1-cyclone dust collectors, 2-flow mixing device, 3-ozone generating-device, 4-oxidation reaction tower, 5-activated carbon adsorber, 6-blower fan.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, the utility model comprises cyclone dust collectors 1, flow mixing device 2, ozone generating-device 3, oxidation reaction tower 4, activated carbon adsorber 5, blower fan 6.Cyclone dust collectors 1 left part is provided with the import of sludge drying foul waste gas, and top is provided with waste gas outlet; Oxidation reaction tower 4 is connected to by flow mixing device 2 after ozone generating-device 3 produces ozone; Sludge drying foul waste gas is first by cyclone dust collectors 1, and the dust particles in sludge drying foul waste gas rotates along cylindrical wall and declines, and effectively removes the dust particles in waste gas; The sludge drying foul waste gas eliminating dust particles is delivered to oxidation reaction tower 4, by the strong oxidizing property oxidative degradation foul waste gas of ozone after mixing together with ozone in flow mixing device 2; Then be delivered to activated carbon adsorber 5, not degrade foul waste gas molecule completely if be delivered to existence in activated carbon adsorber 5, the active carbon in activated carbon adsorber 5 carries out suction-operated to it, ensure that the gas in exit is clean gas; Exist not completely and the ozone that reacts of malodor molecule if be delivered in activated carbon adsorber 5, then ozone can utilize the malodor molecule of absorption in its strong oxidizing property degrading activity charcoal, while guarantee exit gas is clean gas, also make active carbon be regenerated, reach the object of ordorless pollution, non-secondary pollution; Clean gas is by the outer row of blower fan 6.
Below be only that simple declaration has been done to embodiment of the present utility model; be not to restriction of the present utility model; it can have a lot of distortion, the distortion that any same technical professional carries out according to the utility model, all thinks and belongs to protection domain of the present utility model.
