Abstract

The utility model discloses a water spray dust removing device used for equipment, such as a boiler furnace. An air inlet pipe is sheathed in a wind outlet chamber, and the bottom of the air inlet pipe has a water spray device; the inside of the device has an elevator pipe and a nozzle, and the water spray device can float up and down following the water-level change. When the dust removing device works, under the effect of the pressure, the nozzle can spray out drizzle-shaped water beads; dust gas can pass through the drizzle, and the powder dust can be stuck by the water beads, so the gas can be purified.

Description

Water spray dust remover

The utility model relates to a kind of water spray deduster that is used for boiler.

The utility model is by " dust removal design reference " the 130th page to the 139th page disclosed disintegrating scrubber development.

Disintegrating scrubber is to utilize height of water level to seal gas channel and form negative pressure, and swash is become spray, and flue dust passes dedusting from spray.Because the spray of impulse is thicker, the chance that flue dust contacts with spray is less, so efficiency of dust collection is poor.And when air quantity changed, the change of water level was very big, and water level is difficult to control, and the water that overflows is a lot, caused easily for the second time and polluted.Adopt this deduster, efficiency of dust collection is poor, and power consumption is many, and water consumption is big, and structure is huge, involves great expense.

The purpose of this utility model is that a kind of improved deduster will be provided.It is the efficiency of dust collection height not only, and can reduce water power consumption, avoids polluting for the second time.

Technical solution of the present utility model is: has one and cylindrical or square go out air compartment (4) and one and be inserted in out the air compartment center, and blast pipe in parallel (5).Going out air compartment places on the support (11), support is positioned on ash bucket (2) lining, there are a flowing water mouth (14) and a float valve (10) of controlling water level in dust removing machine (1) straight cutting ash bucket bottom at edge, ash bucket upper end, and a magnetic valve that is connected with float valve (9).Retaining ring on one (6) is housed in the air-out indoor, and the circle mouth is lower than the outer.In the air inlet pipe outside, below the last retaining ring, the following retaining ring (15) of " umbrella " shape is arranged.In the air inlet pipe bottom water injector (16) that is suspended in the water surface is arranged, trunnion (7) and nozzle (3) are arranged in the device, its bottom center's place's projection, there is a vertical backstay (13) at the bottom centre place, and backstay inserts locating hole (17) lining on the support.Special character of the present utility model is: air inlet pipe (5) is inserted in discharge chamber (4) center and in parallel, and the air inlet pipe bottom is connected with water injector.

Water injector of the present utility model (16) is a peviform, and can fluctuate with SEA LEVEL VARIATION, trunnion (7) is arranged in the device and be installed in trunnion bottom, spout several nozzles (3) up, trunnion can be regulated the cross section automatically with floating of water injector, and injection flow rate can be regulated automatically with the air quantity size.

Air inlet pipe of the present utility model (5), to go out air compartment (4), nozzle (3), water injector (16), ash bucket (2) be that nonmetal or metal material is made by pottery, glass etc.

Compare with known " Swashing type " deduster, water spray deduster of the present utility model is different with " Swashing type " in the water spray dedusting.That is to say that the utility model is when utilizing air communication to cross trunnion, because the trunnion cross section diminishes, form pressure differential, make nozzle ejection " drizzle " shape globule, from " drizzle " when flue dust passes, the chance that " drizzle " contacts with flue dust is more, so the efficiency of dust collection height, and dust removal efficiency will be greater than 99%.Because the cross section of trunnion is to regulate its size automatically with the change of air quantity.This has guaranteed the stable of injection flow rate, thereby has guaranteed the stable of efficiency of dust collection.Water spray deduster of the present utility model also has the characteristics of saving water power, and after the water spray dedusting, water flows back to again in the ash bucket, can be recycled, and can not pollute and waste.Simultaneously, the air channel is unimpeded, and equipment resistance is little, has reduced the power of air exhauster.In addition, the utility model also has novel structure, simple, compact characteristics, and has that water level is easy to control, floor space is little, installation, maintenance is convenient, long service life, advantage such as cheap.

Following accompanying drawing has been described an example of the present utility model.

As figure is profile of the present utility model.

After air exhauster starting, dirt gas enters into trunnion (7) lining of water injector (16) from inlet pipe (5), because the trunnion sectional area diminishes, the dirt gas velocity increases, and nozzle (3) is in pressure and descends.Owing to atmospheric effect, water is evenly ejection from nozzle (3) again, and shape is as " drizzle " shape globule, and dirt gas passes from " drizzle " in air-purifying chamber (12) lining, and the dust in the sticking dust removal gas of the globule of " drizzle " also falls into ash bucket (2) lining.Purified gas just comes out in air-purifying chamber, walks around down retaining ring (15), passes through retaining ring (6) back again and discharges.The dust that falls into during dedusting in the ash bucket can regularly use dust removing machine (1) to get rid of.Water level in the ash bucket can be regulated voluntarily by the gravity flow mouth of a river (14) and float valve (10).Magnetic valve in deashing process (9) must have been established by cable, when water level descends, and cursory also decline thereupon.Float valve (10) opens, and water flows into ash bucket through magnetic valve, float valve.When water level rises, cursory also rising thereupon.When reaching given water level, float valve will be closed automatically, stops to supply water.Dust in ash bucket increases gradually, and when water level was gone up, unnecessary water can overflow voluntarily from discharge outlet (14).

Claims

1, a kind of water spray deduster, have one and go out air compartment (4), retaining ring on one (6) is housed in the air-out indoor, in the air inlet pipe outside, last retaining ring below, the following retaining ring (15) that " umbrella " shape is arranged, there is of the present utility model being characterised in that of a flowing water mouth (14) dust removing machine (1) straight cutting ash bucket bottom at edge, ash bucket upper end:
