Description
Technical Field
The utility model belongs to the technical field of pollutant treatment, and particularly relates to a low-emission device for pollutant treatment in shale and gangue brickwork plants.
Background
The exhaust gases from the tile manufacturing process typically come primarily from kiln combustion and tile firing processes; these exhaust gases contain pollutants such as carbon dioxide, nitrogen oxides, and carbon monoxide produced by the combustion of the fuel. Contaminants in these exhaust gases can have a negative impact on the environment and health. Wherein nitrogen oxides and carbon monoxide are greenhouse gases contributing to global climate change; in addition, exhaust emissions such as sulfur dioxide, nitrogen oxides, and particulates can also cause air pollution, which can be a hazard to human health.
The standard GB29620-2013 specifies the atmospheric pollution emission limits of the brick and tile industry production process, which specify a particulate emission limit of 30mg/m 3, a sulfur dioxide emission limit of 150mg/m 3, and a nitrogen oxidation (in terms of NO 2) emission limit of 200mg/m 3.
In part to further facilitate atmospheric pollution abatement, more stringent local tile industry atmospheric pollutant emission standards have been established, for example, anhui province limits particulate emissions to 10mg/m 3, sulfur dioxide emissions to 50mg/m 3, and oxynitrides (in terms of NO 2) emissions to 150mg/m 3; henan province limits the particulate emissions to 10mg/m 3, sulfur dioxide emissions to 50mg/m 3, nitrogen oxidation to (in terms of NO 2) emissions to 100mg/m 3, and it is important to see how to achieve low emissions of pollutants in the tile industry atmosphere.
The existing liquid supply waste gas treatment system for manufacturing bricks and tiles mainly comprises a fan, a gas pipe, a buffer tower and a desulfurizing tower, wherein the fan, the buffer tower and the desulfurizing tower are connected in series through the gas pipe. In the prior art, the treatment of pollutants in a desulfurizing tower is generally adopted, and the desulfurizing tower mainly comprises a water tank for storing spray liquid, a spray pipeline, a spray nozzle and a water pump for conveying the spray liquid; the fan conveys the waste gas into the gas pipe, and then enters the desulfurizing tower through a section of gas pipe after passing through the buffer tower, and the spraying liquid such as alkaline water or lime water in a water pool is conveyed to a spraying nozzle in the desulfurizing tower through a water pump, so that spraying treatment is carried out in the desulfurizing tower.
For example, a desulfurization dust collector for a brick factory described in chinese patent document CN204865511U has a main body and a cone, the lower end of the cone is connected with the upper end of the main body into an integral structure, the lower part of one side of the main body is provided with an air inlet, the bottom of the main body is provided with a sewage outlet, the top of the cone is provided with an air outlet, the lower part in the main body is provided with a cyclone, the middle part in the main body is sequentially provided with a primary spray filling device and a secondary spray filling device from bottom to top, and the top in the main body is provided with a defoaming device.
However, because the internal space of the desulfurizing tower is larger, the spraying points needing to be arranged are more, the rectangular array arrangement mode is generally adopted for setting the spraying points, and because the spraying points are more, the number of water pumps needing to be adopted is larger, the spraying requirements of all the spraying points can be met, so that the power of the water pumps has to be increased, and the water quantity and the energy consumption are increased; however, the spraying water yield of part of spraying points is still uneven with the water yield of other spraying points, so that part of waste gas passes through a region with smaller spraying water yield and cannot be effectively treated, and finally discharged waste gas is not up to standard.
Disclosure of utility model
The utility model aims to provide a low-emission device for pollutant treatment substances in shale and gangue brickwork, which solves the problems that the water consumption and the energy consumption are large in the waste gas treatment process, and the discharged waste gas still has partial substandard.
In order to achieve the above object, the technical scheme of the present utility model is as follows: the low emission device for the pollutant treatment objects of shale and gangue brickkiln plants comprises a first spray pipe and a second spray pipe which are fixedly connected to the side wall of a gas pipe;
One end of the first spray pipe extends into the gas pipe, and one end of the first spray pipe, which is positioned in the gas pipe, is communicated with a first spray ring pipe, one end of the first spray ring pipe, which is far away from the first spray pipe, is of a closed structure, and the first spray ring pipe is not contacted with the inner side wall of the gas pipe;
one end of the second spray pipe extends into the gas pipe, the end of the second spray pipe, which is positioned in the gas pipe, is communicated with a second spray ring pipe, one end of the second spray ring pipe, which is far away from the second spray pipe, is of a closed structure, the diameter of the second spray ring pipe is smaller than that of the first spray ring pipe, and the second spray ring pipe is not contacted with the first spray ring pipe;

The technical principle of the scheme is as follows:
The spray liquid is conveyed into the two spray ring pipes through the water pump, and because the two spray ring pipes form an inner ring structure and an outer ring structure, the spray liquid sprayed by the spray nozzle can uniformly cover the section of the gas pipeline, when the exhaust gas flows out, the exhaust gas can pass through the spray liquid areas, and the spray liquid in each spray area is uniform, so that almost all the exhaust gas passing through can be effectively treated. And the number of the spray nozzles is smaller, and the corresponding water pumps are also smaller, so that the water quantity and the energy consumption are reduced.
The adoption of the scheme has the following beneficial effects:
1. According to the scheme, the spraying part is moved into the gas pipeline by the desulfurizing tower, because the gas pipeline space is smaller than the desulfurizing tower space, the inner and outer ring spraying structures of the first spraying ring pipe and the second spraying ring pipe are adopted, compared with the prior art, fewer spraying nozzles are adopted, namely a spraying barrier can be formed in the gas pipeline, flue gas needs to pass through the spraying barrier in the process of conveying to the desulfurizing tower, the flue gas can be promoted to be sprayed by spraying liquid, the spraying effect is improved, and the low emission of pollutants such as follow-up particles, sulfur dioxide, nitrogen oxides and the like is ensured.
2. Compared with the prior art, the number of the spray nozzles is obviously reduced, the requirement on the water pump is reduced due to the reduction of the number of the spray nozzles, and each spray nozzle can be maintained to uniformly output spray liquid for spraying under the action of fewer water pumps, so that compared with the prior art, the total power of the required water pump is lower, the number of the spray nozzles and the water pump is reduced, and the cost is saved; on the other hand, the water consumption is saved.
3. According to the scheme, the content of pollutants in the finally discharged waste gas can be ensured to be far lower than the atmospheric pollution emission limit of the brick and tile industrial production process specified in the GB29620-2013 standard of the atmospheric pollutant emission Standard of the brick and tile industry.

Further, the diameter ratio of the first spray ring pipe to the gas pipe is: 3:4;
the diameter ratio of the second spray ring canal to the first spray ring canal is: 2:3.
The beneficial effects are that: the diameters of the first spraying ring pipe and the second spraying ring pipe are reasonably set, so that the space between the first spraying ring pipe and the gas transmission pipe and the space between the second spraying ring pipe and the first spraying ring pipe are kept in the coverage area of the spraying nozzle, and the effective spraying of the spraying liquid on the waste gas is ensured.
