Abstract

The utility model relates to a chemical liquid dust remover, particularly a dust remover which uses alkaline liquid which is contained in a tank to adsorb and dissolve sulfide and minute dust in ash laden gas. The chemical liquid dust remover of the utility model comprises an air intake duct (1), an exhaust duct (5), a water storage tank (6) which is used for containing a glass tube type water level gauge (7), and a slag outlet (8) which is arranged on the lower end of the water storage tank (6). The air intake duct (1) which is inserted into water can enable harmful gas in flue gas to fully react with an alkaline substance (9) in the water to generate harmless precipitates to be discharged from the slag outlet (8). The harmless gas which is purified can be discharged through the exhaust duct (5) which is provided with an induced draft fan (4).

Description

The chemical liquid deduster

The utility model relates to a kind of, and the deduster that is made of tank body particularly adsorbs the pernicious gas in the flue gas and the deduster of fine dusts by the akaline liquid in the tank body.

Propelling along with expanding economy and modern construction process, problem of environmental pollution is more and more paid close attention to by common people, the a large amount of fume emissions that produced by fuel oil, coal-burning boiler are in the air, pollution to air is very serious, damaging the health of human body, affect the growth of crop, directly destroyed ecological environment.

Under the condition of present dedusting technology, efficient is higher when capturing the grit of particle diameter more than 5 microns, and capture rate is very low during to pernicious gases such as the grit below 1 micron that contained in the flue gas and carbon black and sulfur dioxide, thoroughly air conservation.

The utility model is the defective at existing dedusting technology, provides a kind of mechanical air inducing to force flue gas to come a kind of deduster of dust-removal and desulfurizing by the akaline liquid in the tank body.

The purpose of this utility model is such realization: earlier the baffle plate on the exhaust gases passes is inserted tight, the ash-laden gas that does not purify is introduced admission line in this device insertion water, utilize the blast of air-introduced machine to take away in the tank body, the air that liquid level is above, making not the ash-laden gas that purifies be uniform blister from the water of admission line bottom comes up and replenishes the air of taking away, discharge by the pipeline that air-introduced machine is set, thereby the ash-laden gas and abundant hybrid filtering of akaline liquid and the chemical reaction that do not purify have been formed, generating water-fast sediment all is trapped in the liquid, and pernicious gases such as sulfur dioxide contained in the flue gas also are dissolved in the water, reached dust-removal and desulfurizing and finished synchronously.

The utility model is compared with existing dedusting technology, can not only the good adsorption effect be arranged to grit below 1 micron and carbon black, and sulfur-containing oxide is had purification function efficiently.

, be described further concrete structure and operation principle thereof below in conjunction with embodiment and accompanying drawing thereof according to the chemical liquid deduster that the utility model proposes.

Accompanying drawing is according to the structure of the chemical liquid deduster that the utility model proposes and the schematic diagram of operation principle thereof.

(1) admission line in the accompanying drawing, (2) air inlet damper, (3) liquid, (4) air-introduced machine, (5) discharge duct, (6) water tank, (7) glass tubular type water gage, (8) slag notch, (9) alkaline matter, (10) sewage draining valve, (11) filtering ponds, (12) clear water medical solution pool, (13) small pump, (14) reverse stop valve, (15) water pipe, (16) natural air channel barrier, (17) natural air channel, (18) chimney

With reference to accompanying drawing, ash-laden gas by hot burning device boiler export discharging, insert the alkaline matter (9) that liquid (3) neutralization of the water tank (6) of outer setting glass tubular type water gage (7) is contained in the liquid mixes by admission line (1), make alkaline matter (9) in pernicious gas such as sulfur dioxide in the ash-laden gas and the liquid (3) through filtering and chemical reaction, generate water-fast compound precipitation, the innocuous gas after the purification enters chimney (18) by the blast of air-introduced machine (4) through discharge duct (5).

For the ease of removing the sediment in the water tank (6), the filtering ponds (11) that set out cinder notch (8) sewage draining valve (10) in the lower end of water tank (6) and be arranged on sewage draining valve (10) below make ash and moisture from carrying out neutralisation treatment, and the anti-waste liquid of going up is to secondary environmental pollution.

Filtering ponds (11) communicate with clear water medicine pond (12), and clear water medical solution pool (12) is connected with small pump (13) reverse stop valve (14) water pipe (15), connect the upper end of water tank (6), recycle for the moisturizing dosing.

For making boiler still have the function of gravity-flow ventilation when blowing out or the banking fire, the natural air channel barrier (16) that the setting of admission line baffle plate (2) and natural air channel (17) front end is set in the rear end of admission line (1) is answered complete opening, makes flue gas enter chimney (18) naturally.

When normal operation of boiler was used this deduster, admission line baffle plate (2) and natural air channel barrier (16) should be inserted sternly influenced draft with anti-gas-leak.

For making flue gas after being purified enter chimney (18) smoothly, with the stable operating fluid level of maintenance, by glass tubular type water gage (7), monitor the water level height in the water tank (6), adopt the overflow variable to supply water and control water level, regulate the resistance of flue gas, the blast of balance air-introduced machine (4) guarantees that boiler burns under the state of negative pressure.

Implement the utility model chemical liquid deduster, can stop the pollution of flue dust, effectively preserve the ecological environment atmosphere.
