Abstract

The utility model relates to an improved steam-condensing dust remover, comprising a dust removing chamber, a vaporizing device, a gas-water separator and a water processing pool. The utility model has the advantages of simple structure, smoke and dust removing ability, low cost and easy installation. The steam-condensing dust remover is suitable to be used in medium and small-sized industrial furnaces for removing smoke and dust.

Description

Steam-condensing dust remover

The utility model is a kind of smoke abatement device that is applicable to middle-size and small-size kiln.

At present general smoke abatement device has water jet scrubber, sack cleaner etc., they or volume is big, cost is high, or the Industrial Stoves that are unsuitable for high temperature, high humidity use.Therefore, middle-size and small-size kiln generally is unkitted smoke abatement device." water-mixed smoke abatement device " patent of inventor's application, authorize, the patent No. 87200905, it be a kind of simple in structure, cost is low, and can handle the smoke abatement device of high temperature, high humidity dusty gas, but find that in force the water yield of this equipment dirt pocket (spray part) needs often adjust according to flue-gas temperature, otherwise as gasification insufficient, smoke medicining dust-removing effect is undesirable, still has black smoke and emerges from chimney.In addition, the flue gas water content behind spraying and dedusting is big, when air-introduced machine is extracted out, influences fan life, and the dirt powder in the water droplet is deposited on the air-introduced machine blade, and fan performance is descended.

Task of the present utility model provides a kind of improved smoke abatement device, and it can adjust the water vapour amount with flue-gas temperature, makes atomizing evenly, improve dust removing effects, thoroughly eliminate black smoke, and reduce, improve the air-introduced machine condition of work through the water content in the air-introduced machine flue gas.

The purpose of this utility model is achieved in that a complete set of equipment except that comprising dirt pocket and water treating pond, also sets up the device that makes cold water give the heat vaporization at dirt pocket smoke inlet place, at box gas and water separator of dirt pocket smoke outlet tipping.When hot flue gas enters dirt pocket, the shower water heating that import department flows into from vaporizer is vaporized, vapours is mixed with cigarette vapour after the first road nozzle enters dirt pocket, the water curtain that forms through its several roads, below nozzle makes big portion dirt powder with falling under water again, enters treatment pond, velocity of flue gas slows down the moisture separator and flue gas enters from the dirt pocket outlet, temperature reduces, and the moisture content in the flue gas becomes drippage down, and flue gas is evacuated to chimney by air-introduced machine.

The vapourizing unit that the utility model adopts is the framework that is communicated with by the inner chamber that steel pipe is welded into, and 1～4 framework can be installed, and can certainly be other form, and unified outlet and inlet are arranged; Moisture trap of the present utility model is a rectangular box body, and there is vertical partition plate the centre, and the import of flue gas and outlet are respectively in the bottom of dividing plate both sides.Flue gas is crossed dividing plate from bottom to top, discharges from outlet from top to bottom again, and speed descends at the volley, and water droplet falls, and reaches the effect that reduces moisture.

Details of the present utility model is provided by following examples and accompanying drawing thereof:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a dirt pocket cutaway view among Fig. 1.

Fig. 3 is a vaporizer amplification assumption diagram among Fig. 1.

With reference to the accompanying drawings, the utility model comprises dirt pocket, sedimentation basin.Vaporizer 8 is equipped with at the place at the dirt pocket gas approach, and it has four steel pipes to be welded into the quadrangle that inner chamber is communicated with, and shower water feeds interior tube chamber 7 from the end opening of vaporizer 8, and the steam after the vaporization is from vaporizer 8 ejections suitable for reading.Cold water is supplied with the pump of outlet pressure 0.1MPa pressure, uses the valve regulated water yield, and the Lower Half of vaporizer 8 is liquid usually, the first half is changed into steam state, and with the variation of flue-gas temperature, the vapour amount is increase and decrease thereupon also, automatically regulate, spray in the casing 1 by first row's injection assembly 2 and mix with flue gas.Casing 1 rectangularity, 3～4 row's nozzles are set in the case, there is the dividing plate 4 of inclination each row's nozzle 2 below, bottom half has delivery port 8 water flowing treatment ponds, exhanst gas outlet 9 connects moisture trap 5, and it is a rectangular box, and there is the dividing plate 6 that stands vertically in the bottom at the middle part, delivery port water flowing treatment pond is arranged at the bottom near gas approach, and opposite side is established exhanst gas outlet.

Water treating pond of the present utility model is modified on the prior art basis slightly, it is the pond that is built into brick, cement, internal layer is made waterproof, twice half dividing plate is arranged in the pond, support the iron net with angle bar between the twice dividing plate, top place mat chiltern filter course, whole pond are divided into settling tank 12, filter course 11, clear water reserviors 10 3 parts.Chi Shuizhong adds the NaOH neutralization, makes water maintain PH8～10, and the clear water after the filtration can be recycled.Extract mud with slush pump.

Claims

1, a kind of steam condensing cleaner, it comprises dirt pocket and water treating pond, it is characterized in that:

(1) device that makes the vaporization of part shower water is equipped with at the gas approach place of box dirt pocket.

(2) smoke outlet of box dirt pocket is connected to a box gas and water separator;

2, cleaner according to claim 1 is characterized in that, said vapourizing unit is the quadra that is communicated by the inner chamber that steel pipe is welded into, and can establish 1～4 square frame, lower water inlet, and steam (vapor) outlet is arranged at top.

3, cleaner according to claim 1 is characterized in that, said gas and water separator is a rectangular box, in vertical partition plate is arranged, lower box one side has air inlet, opposite side has the gas outlet.

4, cleaner according to claim 1 is characterized in that said water treating pond comprises sedimentation basin, filter course and clear water reserviors.
