Abstract

The utility model relates to a smoke abatement dust remover, which belongs to the waste gas disposal device of a boiler, and solves the problem that the common boiler does not have ideal dust removal and smoke abatement effects. A cuboid box body with the lower part containing water and a special structure of a special channel consisting of a plurality of upper and lower air wind shield plates in staggered arrangement in the box body are used, and the gravity dust removal and the wet method dust removal are combined, with especially good smoke abatement effect, therefore the utility model can be used for small civil boilers.

Description

Device for abatement of smoke and dust

The utility model belongs to the emission-control equipment technical field of general boiler.

Known to the applicant, the dust arrester of small-sized in the market civil boiler chimney generally can only remove a certain amount of grit, and smoke effect is unsatisfactory, is unfavorable for environmental protection.

The purpose of this utility model is to make a kind of simple structure, gravitational dust collection and wet dedusting are combined, the heavy particle grit in the flue gas is deposited in the water, simultaneously the black smoke in the flue gas is forced the water filtration of wetting, when dust removing effects is greatly improved, obtain smoke effect preferably.

The utility model is design like this: a kind of device for abatement of smoke and dust is characterized in that: a rectangular box bottom of going to the bottom and tilting into part, filled with water, on the casing top gas approach has been arranged, at the casing right flank, the flue gas after being purified outlet has been arranged; At gas approach and purify casing top between the exhanst gas outlet, the specific channel of forming by the upper and lower deep bead of some groups of interlaced arrangements; Water inlet pipe and overflow pipe are equipped with in middle part, side at the deduster casing, and bottom half is equipped with blowoff valve.

The cross section of deep bead is a circular arc.

Distance between following deep bead and the last deep bead is significantly less than the distance between deep bead and the following deep bead.

When ash-laden gas enters at a high speed in the casing from deduster top air inlet, rise behind the chance water surface and circle round, enter the passage of forming by some upper and lower deep beads, discharge by the gas outlet at last.When passage that flue gas is formed by following deep bead and last deep bead, be from top to bottom, because between the two apart from less, this moment, flue gas flow rate was very fast, the impact water surface, absorbed portion moisture, the rising of turning back.When entering between deep bead and the following deep bead passage, because spacing is bigger here, flue gas flow rate slows down, and is sweeping along the heavy particle grit of moisture just to be left in the water, and the part cigarette is also absorbed by water.So repeatedly repeatedly, the cigarette in the flue gas and the dirt overwhelming majority are stayed in the casing, purify the back and discharge by the gas outlet.

The utility model is through on-the-spot on probation, can remove in the flue gas harmful components more than 90%.The utility model simple structure, cheap, environment protecting is good.Be specially adapted to small-sized civil boiler.

The contrast accompanying drawing is further described the utility model below.

Fig. 1 is an aufbauprinciple schematic diagram of the present utility model.

Fig. 2 is the A-A cutaway view among Fig. 1.

Among the figure: 1. 4. times deep beads of deep bead, 5. water 6. on air inlet 2. casings 3.

Water inlet pipe 7. blowoff valves 8. 9. overflow pipes of giving vent to anger

As can be seen from Figure 1, casing 2 is a cuboid basically, and just wherein a part tilts, and in its bottom, blowoff valve 7 is housed.There is air inlet 1 on the top, left side of casing 2, and there is gas outlet 8 on the right side.Be equipped with some between the two and go up deep bead 3 and following deep bead 4, the distance between following deep bead 4 and the last deep bead 3 is significantly less than the distance between deep bead 3 and the following deep bead 4.Be staggered, form specific channel.At casing one middle side part, water inlet pipe 6 and overflow pipe 9 are housed.As can be seen from Figure 2, the cross section of deep bead is a circular arc up and down.

Before the work, open water inlet pipe 6, make water enter casing 2, reach certain water level after, some is under water for following deep bead 4, water 5 keeps certain water level by overflow valve 9.When flue gas enters the casing 2 at a high speed from air inlet 1, meet the water surface and turn back, sweeping along moisture, advance along several specific channels of forming by following deep bead 4 and last deep bead 3.Because down the spacing between deep bead 4 and the last deep bead 3 is less, flue gas flow rate is very fast, is again from top to bottom, and flue gas stream rushes at and adsorbing moisture behind the water surface and turn back; Because the spacing between last deep bead 3 and the following deep bead 4 is bigger, this moment, flue gas slowed down, and was in propradation again again, and heavy particle grit is got rid of in water, and the also moisture posterior synechia of part flue dust becomes and heavily drops in the water.After repeatedly such repetitive process, it is clean that flue gas has become, and 8 discharge from the gas outlet.Dust-laden waste water is discharged otherwise processed from blowoff valve 7.The deep bead cross section causes circular arc up and down, is in order to reduce the dead angle, to improve the operational efficiency of smoke abatement and dust control.

Claims

1. a device for abatement of smoke and dust is characterized in that: a rectangular box bottom of going to the bottom and tilting into part, filled with water, on the casing top gas approach has been arranged, at the casing right flank, the flue gas after being purified outlet has been arranged; At gas approach and purify casing top between the exhanst gas outlet, the specific channel of forming by the upper and lower deep bead of some groups of interlaced arrangements; Water inlet pipe and overflow pipe are equipped with in middle part, side at the deduster casing, and bottom half is equipped with blowoff valve.

2. device for abatement of smoke and dust according to claim 1 is characterized in that: the cross section of upper and lower deep bead is a circular arc.
