Description
Technical Field
The invention belongs to the field of environment-friendly equipment, relates to relevant equipment for waste gas treatment, and particularly relates to a novel waste gas treatment system for treating coal-fired flue gas.
Background
The waste gas treatment mainly refers to the treatment of industrial waste gas such as dust particles, smoke and dust, peculiar smell gas and toxic and harmful gas generated in industrial places. Common waste gas treatment includes factory smoke waste gas purification, workshop dust waste gas purification, organic waste gas purification, waste gas peculiar smell purification, acid-base waste gas purification, chemical waste gas purification and the like. The common methods are as follows: the water absorption method, the aeration activated sludge deodorization method and the multi-medium catalytic oxidation process have the advantages that the waste gas pollutes air seriously, so strict requirements are made for waste gas treatment environmental protection departments of chemical plants, and the waste gas can be discharged after the treatment of each plant reaches the standard. Aiming at the problems that a large amount of waste gas exists in the production and processing processes of brazing parts, for example, certain harmful gas exists in the processing processes of a brazing furnace and a tin dipping furnace for workpieces, equipment specially used for treating the waste gas does not exist in the prior art, the harmful gas generated in the production can be diffused in a workshop, and the polluted air influences the human health of workers, so that a new technical scheme is urgently needed to solve the technical problems.
Wherein, the industrial boiler generally uses coal as fuel, and the coal-fired flue gas contains a large amount of toxic gases and pollutants such as micro-dust particles, sulfur dioxide, nitrogen oxide, carbon black and the like, and generally seriously exceeds the upper limit specified in the national boiler atmospheric pollution discharge standard.
In order to solve the problem that the boiler smoke emission seriously exceeds the standard, a purification tower is generally adopted for purification treatment before the smoke emission, so that the smoke emission meets the national emission standard of boiler air pollution. The inner structure of present purifying tower generally includes spray set and purifier, and purifier generally adopts the defroster, and the defroster is located spray set's top, and spray set is used for spraying alkaline solution, and if magnesium oxide absorbs the method, spray set sprays magnesium hydrate solution, makes sulfur dioxide in the flue gas and magnesium hydrate take place to react and generate magnesium sulfite, and the defroster then gets rid of the water smoke in the flue gas, further purifies the flue gas. However, because a lot of dust particles, sulfur dioxide and other harmful gases still exist in the flue gas passing through the spraying device, the demisters cannot be further removed, so that the flue gas discharged through the chimney at the top of the purification tower still hardly reaches the national emission standard for atmospheric pollution of boilers.

The inclined spraying pipe comprises a spraying pipe body, for the spraying pipe body, the spraying pipe body needs to be designed into a straight pipeline, so that the flowing speed of liquid can be ensured, a spiral flow deflector is arranged inside the spraying pipe body, for the spiral flow deflector, as shown in figure 7, the shape of the spiral flow deflector is mainly used for purifying liquid in a solution space, and the spiral flow deflector can move fully in the spraying pipe body, so that the solution achieves the optimal moving effect, namely the reaction effect of the solution and waste gas is improved; the inner side of the spray pipe body is provided with spray holes, corresponding spray heads are arranged in the spray holes, and for the arrangement positions of the spray holes, the inventor conducts a large number of tests to obtain a design scheme that only one row of spray holes are arranged on one spray pipe body, the design positions of the spray holes are opposite to the central axis of the purification tower body, namely, a solution sprayed by the spray heads forms regular collision reaction with upstream waste gas, namely, if the spray holes are designed into a plurality of rows, the phenomenon of interaction between the spray holes on one spray pipe body can occur, namely, the solution can lose part of acting force, and the purpose of acting force on the waste gas is also lost.
The first controllable rotating mechanism comprises a first driven gear ring arranged on the outer side of the lower fixed shell and a main body gear assembly arranged on the connecting and fixing frame and matched with the first driven gear ring, the first driven gear ring and the lower fixed shell are connected in a welding mode to be connected and fixed, the first driving gear assembly is arranged to be matched with the first driven gear ring, the first driving gear assembly comprises a first driving gear matched with the driven gear and a first controllable driving motor used for driving the first driving gear to work, the first driving gear assembly and the lower fixed shell are designed according to the design idea that the first driving gear and the first driven gear ring rotate mutually under the action of the first controllable driving motor, so that the spraying effect of the spraying pipe body is realized, but the first controllable rotating mechanism needs to be designed, the sealing effect of the lower shell of the purification tower and the upper shell of the purification tower is ensured, namely, the gas in the tower body cannot flow out.
The connecting and fixing frame is used for fixing the lower shell and the upper shell of the purification tower, but the improved connecting and fixing frame is not simple in design and comprises the lower fixing frame arranged on the outer side of the lower shell of the purification tower and the upper fixing frame arranged on the outer side of the upper shell of the purification tower, the lower fixing frame and the upper fixing frame are connected and arranged through the controllable hydraulic cylinder, and the controllable hydraulic cylinder is designed to separate the upper fixing frame from the lower fixing frame so as to separate the lower shell of the purification tower from the upper shell of the purification tower.
In addition to the above design, in order to improve the overall effect, the following design is made:
as can be seen from fig. 3, the inventor provided the water inlet at the top of the upper stationary ring housing, so the water inlet was provided on the upper stationary ring housing because the upper stationary ring housing was stationary, i.e., the water inlet pipe on the water inlet was not affected by rotation;
the water circulation treatment device comprises a water storage tank body, and for the water storage tank body, the water circulation treatment device is actually a storage space, namely, a solution sprayed out of the novel spraying mechanism and waste gas can react in a tower body, so the obtained reactant can flow into the water storage tank, and a layering phenomenon can also occur in the water storage tank after long-time precipitation, namely a sewage layer at the bottom and an available water layer at the upper part; in addition, the inventor also sets up the mouth that draws water on the side of water storage tank, has set up the circulation mouth that sets up with drawing water mouthful cooperation on the side of its purification tower upper shell, and its water inlet, circulation mouth, water pipe between set up through water piping connection, have set up the water pump on its water pipe, this part is not drawn completely in the picture, and it is better understood here, even the available water in the water storage tank can recycle.
