Description

A kind of water bath dust collector

Technical field

The utility model belongs to a kind of environmental purification device, relates to a kind of dust arrester, specially refers to a kind of water bath dust collector.

Background technology

At present the dust arrester of application in factories is mainly take bag-type dust and electrostatic precipitation as main, and its main common shortcoming is that production cost is large, and operating cost is high, and maintenance workload is large etc.Indivedual water dedusting technologies mainly contain spray section, foaming tower, Venturi tube, impact or self-excitation dedusting technology, its principle is to utilize the effect of water or other liquid and dusty gas to make grit and sprinkling water droplet in air, moisture film or moistening wall, when device meets, occur moistening, sedimentation, grit is separated from air, although reduced cost, but due to grit in air and water droplet, the mixing probability of moisture film and matter of time cause its detergent power low, effect is unstable, in addition, dust easily and wall, device is pasted and is caused obstruction and sewage not to obtain reusing the more shortcoming of relative water consumption.

Utility model content

For overcoming the above problems, the utility model provides a kind of water bath dust collector, can be widely used in urban environment administer, industrial enterprise's dedusting and other dust more region, control atmosphere pollution effectively, and have simple in structure, operating cost is low, the advantage that maintenance workload is little, in addition, regulate the pH value of water in dust removal also can reduce airborne sulfuric acid, nitric acid equal size, reduce the occurrence probability of acid rain.

For achieving the above object, the utility model is mainly made up of dust cleaning case (1), blast pipe (2), discharge pipe (3), bend pipe (7), air-introduced machine (4) and sewage purification device (5), valve group (6) and water pump (8); The bottom of dust cleaning case (1) connects blast pipe (2), and top attachment discharge pipe (3) connects air-introduced machine (4) after discharge pipe (3), and dust cleaning case (1) bottom connects water pump (8), valve group (6) and sewage purification device (5) successively by water pipe.Wherein dust cleaning case (1) is hollow hemisphere type structure, and bottom connects inner setting the in position of blast pipe (2) and washes wind comb (10), and water compensating valve (12) is set on sidewall; Wash wind comb (10) and adopt many stainless steel tubes or polyester tube welding fabrication, and in the multiple spray wind of offering of its bottom even hole (11), the area sum in spray wind hole (11) is 1.05 ~ 1.25 times of blast pipe (2) cross section; Water compensating valve (12) is motor-driven valve, is arranged on the inner liquid-level switch (not shown) control of dust cleaning case (1), makes the interior water level of dust cleaning case (1) keep just covering and washes wind comb (10); Install the air inlet (21) of screen cloth in the top setting of blast pipe (2) additional, after preventing in rubbish suction apparatus that polybag etc. is larger, result in blockage; In the bottom of bend pipe (7), drain valve (71) is set; Micropore ceramic filter element (51) is equipped with in described sewage purification device (5) inside, and valve group (6) is three position five-way valve; The water in dust removal filling in a kind of water bath dust collector of the utility model is that running water can be also to add basic agent through the middle water of purified treatment to make pH value be greater than 9, to improve air purification effect.

The specific embodiment

A kind of water bath dust collector of the utility model is mainly made up of dust cleaning case (1), blast pipe (2), discharge pipe (3), bend pipe (7), air-introduced machine (4) and sewage purification device (5), valve group (6) and water pump (8) with reference to the accompanying drawings; The bottom of dust cleaning case (1) connects blast pipe (2), and top attachment discharge pipe (3) connects air-introduced machine (4) after discharge pipe (3), and dust cleaning case (1) bottom connects water pump (8), valve group (6) and sewage purification device (5) successively by water pipe.Wherein dust cleaning case (1) is hollow hemisphere type structure, and bottom connects inner setting the in position of blast pipe (2) and washes wind comb (10), and water compensating valve (12) is set on sidewall; Wash wind comb (10) and adopt many stainless steel tubes or polyester tube welding fabrication, and in the multiple spray wind of offering of its bottom even hole (11), the area sum in spray wind hole (11) is 1.05 ~ 1.25 times of blast pipe (2) cross section; Water compensating valve (12) is motor-driven valve, is arranged on the inner liquid-level switch (not shown) control of dust cleaning case (1), makes the interior water level of dust cleaning case (1) keep just covering and washes wind comb (10); Install the air inlet (21) of screen cloth in the top setting of blast pipe (2) additional, after preventing in rubbish suction apparatus that polybag etc. is larger, result in blockage; In the bottom of bend pipe (7), drain valve (71) is set.When work, open air-introduced machine (4) because suction function is entered and washes wind comb (10) through blast pipe (2) by air inlet (21) with the air of dust, with the air of dust wash wind comb cut apart by some air channels in (10) after in water in dust removal bottom multiple spray wind holes (11) drain into dust cleaning case (1), airborne dust and water in dust removal hybrid reaction submerged in the water, except the air of dust is discharged from air outlet (31) after bend pipe (7) and air-introduced machine (4) by discharge pipe (3); Fine liquid particles remaining in air precipitates when through bend pipe (7), and discharges through drain valve (71); Water in dust removal liquid level in dust cleaning case (1) is directly proportional to dust removing effects, be inversely proportional to the load of air-introduced machine (4), the rate of water make-up that can pass through as the case may be the definite value control water compensating valve (12) of adjusting liquid-level switch when use, water compensating valve (12) has the function of chemicals addition control water in dust removal pH value concurrently.For the dust removing effects needs that keep this device often filter water in dust removal, micropore ceramic filter element (51) is equipped with in described sewage purification device (5) inside, valve group (6) is three position five-way valve, when normal use, valve (61), other valve of (63) conducting are closed, sewage purification device normal filtration, water purification is after filtering back in dust cleaning case (1); In the time that mud is more in filter core, open valve (62), (65) close other valve, sewage purification device (5) carries out back flush the mud under filtering is rushed to sludge sump (9), after recoil, opening valve (61), (64) closes other valve and carries out in short-term forward and rinse the mud that is attached to micropore ceramic filter element (51) inwall is also rushed to sludge sump (9), mud employing in sludge sump focuses on mode and processes, and prevents the secondary pollution to environment.Sewage purification device (5) is opened valve (61) after rinsing, (63) are closed other valve and recovered normal operating condition.The water in dust removal filling in a kind of water bath dust collector of the utility model is that running water can be also to add basic agent through the middle water of purified treatment to make pH value be greater than 9, to improve air purification effect.

Usefulness of the present utility model is simple in structure, and operating cost is low, and the advantage that maintenance workload is little in addition, regulates the pH value of water in dust removal also can reduce airborne sulfuric acid, nitric acid equal size, reduces the occurrence probability of acid rain.Can be widely used in urban environment and administer, industrial enterprise's dedusting and other need to be to the region of air cleaning, effectively control atmosphere pollution.
