Description

A kind of three pass dedusting devulcanizers

Technical field

The present invention relates to produce the dedusting desulfurizers such as flue gas, dust, tail gas, pernicious gas for industrial processes, relate in particular to a kind of three pass dedusting devulcanizers.

Background technology

For industrial production state, often can produce a large amount of industrial tail gas every year, cause social environment sharply to worsen, simultaneously ecological environment and living environment are caused very big harm, directly or indirectly cause in recent years the phenomenons such as " acid rain " and climate warming.At present; every country is to environmental protection; particularly to the management of industrial tail gas, dust also in continuous reinforcement; in enviromental protection enterprise's improvement to industrial tail gas at present; the technology category that adopts is also more various, but the shortcoming such as the ubiquity power consumption is large, water consumption is large, floor space is large, investment is large, desulfuration efficiency is low.In order to reach energy-saving and emission-reduction, efficient and invest the purposes such as less, to be badly in need of dust-removing and desulfurization process is innovated, especially corresponding effectively combination of equipment, be intended to realize the purpose of high-efficiency desulfurization.

Summary of the invention

For above defect, the invention provides a kind of device structure advantages of simple, Expenses Cost less, be convenient to safeguard, have energy-saving and emission-reduction effect, obvious three pass dedusting devulcanizers of desulfurized effect, thereby realize the purpose of effective dust-removal and desulfurizing.

For achieving the above object, the present invention is by the following technical solutions:

A kind of three pass dedusting devulcanizers, comprise whirl cylinder, air deflector and filter, the whirl cylinder top port is connected with air deflector, and described whirl cylinder is provided with Wen's larynx, an air inlet is offered in the whirl cylinder outside, is positioned at this air inlet inboard and air channel, Wen's larynx top is respectively equipped with an atomizer; Described air deflector inside some deflectors that are obliquely installed that are staggered from top to bottom, described filter interior is furnished with three to five filter courses from bottom to top successively, and three set levels are respectively the primary layer of removing gas organic components and bulky grain shape material, filter the secondary layer of removing residual inorganic matter in gas and absorbed portion harmful substance, still have three grades of layers of ionic species harmful substance in adsorbed gas.Described whirl cylinder the first half is funnel-form, and the whirl cylinder bottom is provided with stillpot and with the blowdown chamber of below, is communicated with, and described air deflector bottom is offered the circulation air port and by this circulation air port, with external filter, is communicated with; Air deflector and filter below is laid one and is prolonged and stay plate, prolong stay the plate back segment to be provided with to be communicated with the blowdown chamber from discharge orifice.

The beneficial effect of three pass dedusting devulcanizers of the present invention is:

(1) in taking off dirt sulphur removal process,, by the atomizer dosing of spraying for the first time is set at the air inlet place, so that catch and fully with gas, merge to produce, react; Scripture formula larynx arranges atomizer after boosting and entering air deflector, with the dosing of spraying for the second time, makes gas again with medicine, carry out effecting reaction; Air deflector has extended the reaction time of medicine and pernicious gas, can improve reaction efficiency; Finally by the three-stage filtration of crossing in filter, be organic components and the larger particles shape material in elementary removal gas, secondary filter is removed residual inorganic matter and absorbed portion harmful substance in gas, the third level is filtered the ionic species harmful substance that still exists in adsorbed gas, through this three-stage filtration, pernicious gas can effectively be removed again and discharge through air outlet; In sum, can obviously improve desulfurized effect, be conducive to greatly energy-saving and emission-reduction simultaneously;

(2) structure arranges rationally simple, characteristics such as having small volume, be convenient to safeguard, use cost is low, power consumption is few, water consumption is little, can be widely used in the air-polluting dust-removal and desulfurizings such as industrial waste gas, blast furnace gas, boiler smoke, and the improvement of other pernicious gas;

(3) expansibility of equipment is stronger, for example, can add the pest checkout gear at equipment air outlet place, can detect online emissions status, thereby adjust filter efficiency and the loss situation of filter course, if find that efficiency obviously reduces and lower than national examination criteria, can in time change filtering layer; Also can liquid level regulation device be set at the foul water tank floss hole, to reach the vapour pressure dynamic balance.
