Description
Technical field
The utility model relates to a kind of filtering and purifying, especially a kind of boiler dust-removing desulfurating apparatus.
Background technology
Coal is widely used in aspects such as workers and peasants' production and resident living as a kind of energy.Coal-fired general sulfur content also just means 100 kilograms of coals of every burning between 1～3%, promptly generate 2 kilograms of sulfur dioxide, is dissolved in water and can generates about 6 kilograms of sulfurous acid.The pollution that causes like this is quite serious, in order to eliminate the poisonous and harmful substance of discharging in the boiler fired coal smoke evacuation, people have adopted the whole bag of tricks, wet scrubber is arranged, cyclone dust collector, large-scale boiler is provided with sulphur removal equipment, wet scrubber is to utilize water to eliminate the dust of dusty gas, major defect is that volume is big, and water consumption is big, and mud and sewage will be handled once more.Cyclone dust collector is that the centrifugal force that utilizes dust-contained airflow to rotatablely move to produce comes the dust in the divided gas flow, and major defect is can not eliminate the less dust of diameter, can not eliminate sulfur dioxide.The sulphur removal equipment of large-sized boiler equipment, invest huge, during-operation service expense height.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiency of above-mentioned existing boiler dusting sulphur removal equipment, and provides a kind of simple and practical, at the bottom of the cost, the efficient height, and the foam waste gas purification apparatus of applied range.
Realize that the technical scheme that the purpose of this utility model adopts is, a kind of foam waste gas purification apparatus, it comprises tower body; Bottom at tower body is provided with air inlet, is provided with the fluid-tight mouth in the bottom of tower body, is provided with exhaust outlet at the top of tower body; Bottom at the tower body cavity is provided with cyclone separator, described cyclone separator is connected with air inlet, above cyclone separator, be equipped with and make the bubble generating means, described make the bubble generating means below be provided with spray nozzle, be provided with froth breaker above the generating means making bubble.
As a kind of improvement of the present utility model, the described bubble generating means of making is tapered, links to each other with the tower wall all around.
As another improvement of the present utility model, the described bubble generating means of making is divided into one-level and makes bubble generating means and secondary and make the bubble generating means.
As another improvement of the present utility model, be lined with acid-resistant cement at the inwall of described tower body, outer lining fiberglass is anticorrosion.
The beneficial effects of the utility model are: the utility model is the utilization bionics principle, adopt foam to stick new technology, increase waste gas and alkaline medium contacted specific surface area to greatest extent, make that pollutant and the medium in the waste gas fully sticks, thereby be absorbed or neutralize.Therefore, the utlity model has characteristics simple in structure, that cost is low, efficient is high.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the schematic diagram of cyclone separator;
The specific embodiment
As shown in Figure 1 and Figure 2, a kind of foam waste gas purification apparatus of the present utility model comprises tower body 1, is provided with air inlet 4 in the bottom of tower body 1, is provided with fluid-tight mouth 6 in the bottom of tower body, is provided with exhaust outlet 8 at the top of tower body; Bottom at the cavity of tower body 1 is provided with cyclone separator 5, and described cyclone separator 5 is connected with air inlet 4, is equipped with above cyclone separator 5 and makes the bubble generating means, makes the bubble generating means and is tapered, links to each other with the tower wall all around.This is made the bubble generating means and is divided into one-level and makes bubble generating means 3 and make bubble generating means 2 with secondary.One-level make bubble generating means 3 and secondary make bubble generating means 2 below be equipped with spray nozzle 7, above secondary is made bubble generating means 2, be provided with froth breaker 9, on the inwall of tower body 1, be lined with acid-resistant cement.Seal fluid-tight mouth 7 for better water, fluid-tight mouth 7 is outstanding to the tower body bottom.Good for the effect that makes froth breaking, froth breaker 9 is formed by the vertical arrangement of stainless steel thin slice of sawtooth pattern.
Purification process of the present utility model is achieved in that the utility model stands on the top of a circulating water pool, and the water seal mouth of tower body below is stretched under the liquid level of pond, utilizes the air pressure principle to form a liquid seal device.Make infusion by in the pond, adding alkali electroless, make the water in the pond form alkaline mixed solution.Liquid is made bubble by spray nozzle to making the continuous hydrojet of bulb apparatus by outer water pump below making bulb apparatus, form circulation and make the bubble system.When the dust-laden exhaust gas of boiler plant discharging is taken out the cyclone separator of introducing the tower body cavity by the rearmounted air-introduced machine of installing of this equipment, at first remove particle bigger in the flue gas by cyclone separator, rise to the foam storage chamber at middle part then, waste gas is when making the bulb apparatus mesh, carry out chemical reaction at this sulfur dioxide and heavy alkaline foam, sulfur in smoke is thoroughly neutralized, catch the tiny grit in the flue gas simultaneously.As a kind of improvement of the present utility model, the secondary device that froths is set especially, reaction layer by layer, efficient is higher.The middle foam that carries little grit because froth breaker is the stainless steel thin slice of sawtooth pattern, constantly is obstructed when foam passes intermediate gaps when the froth breaker of process top of tower, finish froth breaking, form drop, dust-containing liquid is dropped into sedimentation basin at the bottom of the tower, and Purge gas is discharged from the top of tower outlet.Water process precipitation or filtration back supply recycle in the sedimentation basin, and sediment regularly carries out labor cleaning's outward transport or processing at the bottom of the pond, can recycle.Pond liquid can detect its acid-base value by the HP control instrument, then according to data, carries out liquid and replenishes or change.
