Abstract

An impingement dust collector for granite sweetening mainly comprises walls of the dust collector (1), a smoke inlet passage (2), an S-shapes passage (3), a gas discharging passage (4), a booth-shaped pool groove (5), a water replenishing pipe (6) and an atomizer pipe, wherein the walls of the dust collector is built by granites, the smoke inlet passage (2), the S-shaped passage, (3), the air discharging passage (4) and the booth-shaped pool groove (5) are arranged in the walls of the dust collector and are filled with alkali liquor (51), the smoke gas entered from the smoke inlet passage (2) is sufficiently mixed with atomized water, big dust grains drop downwardly into the water, simultaneously, the atomized water reacts with sulfur dioxide in the smoke gas to achieve the effect of desulfurization and dust elimination in one time, further the smoke gas passes through the S-shaped passage, the gas arouses plenty of sprays to wash the smoke gas again, thereby high degree of purification is realized. The utility model has the advantages of simple structure, low manufacture cost, and easy usage, maintenance and repair.

Description

Fiber crops stone desulfurization impingement dust collector

Technical field

The utility model relates to a kind of environmental protection deduster, particularly has spray and impacts the numb stone desulfurization impingement dust collector of desulfurizing function.

Background technology

Current in the mine, building materials grinding field, foundry in the factory, the boiler room of central heating in the city, the local pollution that all exists dust and flue gas in drinking water boiler room or the like, especially for the city, it is a kind of serious pollution that this situation just all is considered as, and each side is the dust-removal and desulfurizing problem when making great efforts to solve smoke evacuation all.Existing desulfurizing dust-collector, most wet methods that adopt are mainly carried out the purpose that chemical reaction reaches desulfurization by akaline liquid and sulfur dioxide in flue gas, for the anticorrosion agent structure adopts composite product more, but this material moisture-proof is relatively poor, and consequently cost is higher.The applicant once proposed a kind of numb stone spray impact type desulfurizing dust-collector for this reason, the patent No.: 96223075.8, Granted publication CN2279204Y, result of use is better, but, also need carry out some improvement to this technical scheme through use practice and experience after a while.

Summary of the invention

According to background technology, the purpose of this utility model is the numb stone desulfurization of former patent impingement dust collector is carried out some improvement from general structure and each composition parameter, makes it in desulfurization, and dedusting and maintenance use the repairing aspect effective more and convenient.

To achieve these goals, the utility model is achieved through the following technical solutions: a kind of numb stone desulfurization impingement dust collector, mainly by wall of dust arrester (1), flue (2), S shape passage (3), exhaust duct (4), cabinet shaped pool groove (5), filling pipe (6), injection spray pipe (7) is formed, wherein wall of dust arrester (1) is to be built by laying bricks or stones by granite to form, and its inside is provided with flue (2), S shape passage (3), exhaust duct (4), filling pipe (6) and injection spray pipe (7) are installed in flue (2), cabinet shaped pool groove (5) are arranged, alkaline solution (51) is housed in it in the bottom basis instrument of wall of dust arrester (1).

The utility model is built simplify the structure greatly technology and reduced manufacturing cost of wall of dust arrester (1) by laying bricks or stones with granite.

Injection spray pipe (7) is housed in flue (2), makes water atomization, at first high-temperature smoke is dissolved and contain the effect of the desulfurization of the purification that improved flue dust and flue dust by atomized water.

The flue dust that has been cleaned enters S shape passage again, because the acceleration of passage is centrifugal, splashes, and the resultant effect of containing further improved the effect of dedusting and desulfurization.

The utility model can be used for the boiler room, foundry, mine, building materials grinding field etc.

The utility model structure durable, working service is repaired simple and easy.

Description of drawings

Fig. 1 is the utility model general structure cross-sectional schematic

Fig. 2 is the side view of Fig. 1

Among the figure: 1-wall of dust arrester, 11-advance the cigarette interface, the 12-interface of giving vent to anger, 2-flue, 3-S shape passage, 31-blade plate, 32-lower blade plate, 4-exhaust duct, 5-cabinet shaped pool groove, 51-alkaline solution, 6-filling pipe, 7-injection spray pipe

The specific embodiment

By Fig. 1 and Fig. 2 as can be known, the utility model is mainly by wall of dust arrester 1, flue 2, S shape passage 3, exhaust duct 4, cabinet shaped pool groove 5, filling pipe 6, injection spray pipe 7 is formed, and wherein wall of dust arrester 1 is to be built by laying bricks or stones by granite to form, its inside is provided with flue 2, S shape passage 3, exhaust duct 4 is equipped with filling pipe 6 and injection spray pipe 7 in flue 2, basis instrument has cabinet shaped pool groove 5 in the bottom of wall of dust arrester 1, and alkaline solution 51 is housed in it.

As seen from the figure, flue 2 porch are equipped with into cigarette interface 11, in order to being connected with outside flue, also are the technology openings simultaneously, are convenient to maintenance and repair.The exit of exhaust duct 4 is equipped with the interface 12 of giving vent to anger, and is convenient to be connected with the air exhauster (not shown), makes the passage place in the wall of dust arrester 1 form negative pressure when starting owing to air exhauster again, has quickened the flow velocity of flue dust, has sucked the gas of required dedusting simultaneously again.

More as can be known, wall of dust arrester 1 of the present utility model is made for rectangular channel through the passage that S shape passage upwards discharges flue gas again from top to bottom by a side by figure.

Flue dust enters by advancing cigarette interface 11, motion (as shown by arrows) from top to bottom, at first run into the atomized water of injection spray pipe 7 ejections, it is fully mixed with high-temperature flue gas, catch, contain big grit and fall into alkaline solution 51 in desulfurization with purify in servicely, the high temperature that utilizes flue gas to have can well dissolve itself and atomized water, sink thereupon forming the small globule, tiny grit has strengthened quality through the containing of atomized water, and what have falls into liquid, the lower blade plate 32 that passes through S shape passage 3 and the blade plate 31 that have, make its acceleration, centrifugal getting rid of thrown, and a large amount of sprays that splash are caught and contained grit, makes it to wash once more the clean-up effect that flue gas reaches height.

As seen from the figure, S shape passage 3 is combined by blade plate 31 and lower blade plate 32.

Illustrate by Fig. 2, the situation that filling pipe 6 and injection spray pipe 7 are gone into from wall of dust arrester 1 one sides, its position is near advancing cigarette interface 11.

The work of removing contamination for cabinet shaped pool groove both can be adopted labor cleaning's method, also can adopt the purging method of hydraulic flushing ash.
