Abstract

The utility model provides a smoke and dust remover used for a coal burning boiler and other coal burning stoves. The utility model comprises a dust removing box (1), and the utility model is provided with a smoke inlet pipe (2) and a smoke exhaust pipe (3) which are communicated with the dust removing box (1). The improvement of the utility model lays in that a water spray and atomizing device us arranged above the smoke inlet pipe (2) on the dust removing box (1), and a water outlet pipe (4) is arranged on the bottom of the dust removing box (1). The smoke and dust remover with the structure forms one layer of atomizing layer of water above the smoke exhaust pipe in the dust removing box; in a process that smoke passes through the atomizing layer, and dust in the smoke is adsorbed by water and is exhausted from the dust removing box through the water outlet pipe; the smoke exhausted into the air is white, the smoke exhaust pipe does not need to match with a draft fan, and electrical energy is saved.

Description

Smoke dust collector

The utility model relates to a kind of smoke dust collector that is used for coal-burning boiler and other coal furnace.

At present, in known technology, the smoke dust collector that is used for coal-burning boiler and other coal furnace has a dust cleaning case, dust cleaning case and smoke-intake pipe and smoke exhaust pipe are connected, water is housed in the dust cleaning case, the exhaust opening of smoke-intake pipe inserts in the water, the flue gas water flowing layer of smoke-intake pipe is discharged in the air by smoke exhaust pipe, flue gas is in passing through the process of water layer, and water adsorbs the dust in the flue gas, the smoke dust collector of this structure, flue gas is in the process of water flowing layer, flue gas is to pass through water layer with some bubbles, and the dust in the bubble can not be adsorbed with water, and a large amount of dusts is discharged into and causes air pollution in the air; Its another weak point is that flue gas is subjected to very big resistance in the process by water layer, and each needs air-introduced machine and its coupling work that power is bigger smoke-intake pipe and smoke exhaust pipe, and the consumption of electric energy is bigger.

The purpose of this utility model is to provide a kind of smoke dust collector, to overcome the deficiency of known technology.

The utility model is achieved in that a kind of smoke dust collector, it comprises a dust cleaning case (1), having smoke-intake pipe (2) and smoke exhaust pipe (3) connects with dust cleaning case (1), its improvements are upward to have water spray atomising device in the top of smoke-intake pipe (2) at dust cleaning case (1), have drainpipe (4) in the bottom of dust cleaning case (1).

The utility model smoke dust collector can be that the top of smoke-intake pipe (2) has an anti-cover (5) that drenches.

The utility model smoke dust collector can be that water spray atomising device is atomizer (6), and atomizer (6) is connected with feed pipe, and atomizer (6) has the elevation angle obliquely.

The smoke dust collector that the utility model provides, pass through in the process of dust cleaning case at flue gas, dust is atomized the spray water absorption of shower nozzle ejection, discharge dust cleaning case by drainpipe, dedusting is more thorough, is discharged into airborne flue gas and is white in color, owing to the resistance that is subjected at the dust removal process flue gas is less, smoke exhaust pipe need not mate the bleed machine, saves electric energy.

Fig. 1: the master of a kind of structure of the utility model smoke dust collector looks partial sectional view.

The utility model is described in further detail in conjunction with the embodiments with reference to accompanying drawing.

Embodiment 1, Fig. 1 has provided a kind of concrete structure of the utility model smoke dust collector, it comprises a dust cleaning case (1), having smoke-intake pipe (2) and smoke exhaust pipe (3) connects with dust cleaning case (1), the top of going up inlet pipe (2) at dust cleaning case (1) has water spray atomising device, has drainpipe (4) in the bottom of dust cleaning case.As shown in the figure, has an anti-cover (5) that drenches in the top of smoke-intake pipe (2).Can prevent that like this water droplet that sprays from entering in the smoke-intake pipe.Water spray atomising device can be atomizer (6), and atomizer (6) is connected with feed pipe, and atomizer has the elevation angle obliquely.Have several open-works on the atomizer.The number of atomizer is determined according to concrete conditions such as the size of exhaust smoke level and injection flow rates.The smoke dust collector of this structure, in dust cleaning case smoke-intake pipe above form the atomizing layer of one deck water, pass through in the process of atomizing layer at flue gas, dust in the flue gas is adsorbed with water, and discharges dust cleaning case by drainpipe, and dedusting is more thorough, being discharged into airborne flue gas is white in color, because flue gas is less at the resistance that dust removal process is subjected to, smoke exhaust pipe need not mate air-introduced machine, saves electric energy.

Claims (3)

1, a kind of smoke dust collector, it comprises a dust cleaning case (1), have smoke-intake pipe (2) and smoke exhaust pipe (3) and connect, it is characterized in that the top of going up smoke-intake pipe (2) at dust cleaning case (1) has water spray atomising device, has drainpipe (4) in the bottom of dust cleaning case (1) with dust cleaning case (1).

2, smoke dust collector according to claim 1 is characterized in that the top of smoke-intake pipe (2) has an anti-cover (5) that drenches.

3, smoke dust collector according to claim 2 is characterized in that water spray atomising device is atomizer (6), and atomizer (6) is connected with feed pipe, and atomizer has the elevation angle obliquely.
