Abstract

The utility model relates to a double-stage self-exciting type fume purifying machine set. A flue dust separator is arranged on a fume exhausting channel at the front of a draught fan, and a self-excitation type fume purifier is arranged behind the draught fan. Thus, the fume purifying machine set with reasonable arrangement is formed. The self-excitation fume purifier adopts double air inlets and modular design, which is convenient to internal maintenance and cleaning; thus, the installation adaptability to sites with different conditions can be greatly increased. In addition, the utility model has the characteristics of specific work division of the structure, good dust removing effect, small land occupation, easy installation, etc. The utility model is suitable for fume purifying of various boilers and kilns.

Description

Twin-stage auto-excitation type gas cleaning unit

The utility model relates to the industrial smoke dedusting unit that a kind of wet type flue gas desulphurization device combines with other treating apparatus.

At present, in industrial dedusting equipment, hydrofilter is generally used by vast industrial enterprise with the characteristics of its high-effective dust-removing, but, in the concrete use of hydrofilter, but exist many unsatisfactory places, topmost is exactly allocation problem with air-introduced machine, most of enterprises are arranged on air-introduced machine after the deduster, this installation method is to hydrofilter, be dissolved with the aerosol of oxysulfide and nitrogen oxide in the flue gas, water droplet and a small amount of flue dust can attach on the air-introduced machine blade, the corrosion air-introduced machine, and the too thick air-introduced machine load that also can make of laying dust strengthens, infringement motor and other mechanical part, if grieshoch is on-stream shakes, can cause that also the air-introduced machine motion is uneven, powerful centrifugal force is easy causing the accident property device damage often; Another kind is that air-introduced machine is installed in before the deduster, though avoided the deficiency of first method like this, the air-introduced machine wearing and tearing more greatly, not too economical.In recent years, also occurred doing the deduster that wet method is combined into one, studying carefully its purpose only is that wet method is additional mutually, the raising efficiency of dust collection in order to do, and does not play the effect of hierarchical arrangement, protection blower fan yet; The multistep treatment method that adopts two above deduster combinations is also arranged, but occupation of land is big, expense is high and configuration is not complete.

The twin-stage auto-excitation type gas cleaning unit that the purpose of this utility model is to provide a kind of and disposes rationally, long service life, place adaptability are strong, be convenient to maintenance of clean-up.

For achieving the above object, the technical scheme that the utility model is taked is: this unit is arranged on air-introduced machine before the auto-excitation type flue gas cleaner, and the flue dust separator is installed on the air-introduced machine smokejack before as elementary cleaner; The same side of auto-excitation type flue gas cleaner is provided with two air inlets, and two strands of air-flows, two S shape passages internally come together in same aerosol separation chamber, discharge after purifying.

For improving the adaptability in place, for maintenance is provided convenience, on the basis of such scheme, the auto-excitation type flue gas cleaner is designed to split formula structure, is combined from top to bottom by aerosol separation module, auto-excitation type gas cleaning module and sedimentation deslagging module successively.

Twin-stage auto-excitation type gas cleaning unit by the such scheme design, auto-excitation type flue gas cleaner and the classification of flue dust separator are provided with, rational in infrastructure, the division of labor is clear and definite, complete equipment long service life, good reliability, good purification, the auto-excitation type flue gas cleaner takes two inlet structures to optimize the air-flow approach, increased the inner space, modularization split structural design, under the condition that keeps original volume, can adopt different module combinations to adapt to different actual requirements, the maintenance condition is greatly improved, and occasion adaptability strengthens, and performance improves also more potential; The flue dust separator does not additionally take up an area of, and has played the effect of elementary dedusting, protection blower fan.

Fig. 1 is the structural representation of twin-stage auto-excitation type gas cleaning unit;

Fig. 2 is the structural representation of auto-excitation type flue gas cleaner;

Fig. 3 is the structural representation of flue dust separator.

Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail:

As shown in Figure 1, twin-stage auto-excitation type gas cleaning unit comprises flue dust separator 3, air-introduced machine 4 and auto-excitation type flue gas cleaner 5, flue dust separator 3 is arranged on the exit smokejack 2 of boiler (flue dust source) 1, it can carry out elementary dedusting by the big particle diameter soot dust granule that abrasiveness is strong, plays the effect of protection blower fan effectively; Auto-excitation type flue gas cleaner 5 is installed in after the air-introduced machine 4, and pernicious gases such as tiny grit and SOx, NOx are carried out the secondary wet cleaning.After this unit two-stage dedusting, purifying, the dirt of discharging fume reaches national environmental standard.

Figure 2 shows that a kind of embodiment preferably of auto-excitation type flue gas cleaner, be about to body and be designed to split-type structural, combine from top to bottom by aerosol separation module 6, auto-excitation type gas cleaning module 7 and sedimentation deslagging module 8 successively.Wherein the top of a side of aerosol separation module 6, water-stop sheet 10 has access door; Have two air inlets on the same side of auto-excitation type gas cleaning module 7, air-flow comes together in the central same aerosol separation chamber through inner two S shape gas induced passages 11, enters in the chimney through aerosol separation module 6 again, and tiny grit is settled down in the deslagging module 8.The two inlet structures design of auto-excitation type flue gas cleaner 5 not only can be optimized the air-flow approach, and the inner space can be increased be twice about, can reduce by two cleaning faces simultaneously, bring convenience for maintenance and cleaning; Modularized design can adapt to the fabricating yard of different condition, also is convenient to change, keep in repair under the prerequisite that does not influence use.The auto-excitation type flue gas cleaner also can be processed into monoblock type, still adopts two air inlet forms.

Fig. 3 is the concrete structure of flue dust separator 3, and as the flue dust separator 3 of elementary cleaner, its inside is formed in parallel by single flow whirlwind tube 12, and its below is provided with automatic removing dust bucket 13.Whirlwind tube 12 is axial admission, direct current exhaust, the number in parallel of whirlwind tube 12 is determined divided by 2 by the tonnage number of joining boiler, its length generally is controlled in the 1m, only needs to cut down the 1m left and right sides flue during installation and replace with flue dust separator 3 and get final product on the boiler exhaust gas pipeline.
