For the sustainable future development of their respective enterprises, most current steel enterprises actively respond to national requirements and implement environmental protection emission policies.

[0003] However, in the upgrading and transformation of many enterprises, because the original workshop and surrounding facilities were not designed to fully consider future development requirements, when treating flue gas dust, the installation of ground towers and ground water tanks needs to be carried out. However, there is not enough space in the workshop and its surroundings to meet the requirements of equipment renewal and transformation, especially there is no reasonable location for the construction of environmental protection equipment, thus increasing the difficulty of environmental protection transformation. Summary of the Utility Model

[0004] Aiming at the above-mentioned prior art, the technical problem to be solved by the utility model is that when enterprises treat flue gas dust, the original workshop and surrounding facilities were not designed to fully consider future development requirements, there is not enough space in the workshop and its surroundings to meet the requirements of equipment renewal and transformation, and it is difficult to construct and install ground towers and ground water tanks, increasing the difficulty of environmental protection transformation.

[0005] To solve the above problems, the utility model provides a particulate matter treatment device in a flue gas pipeline, which includes two fixed pipes installed on the top of the flue gas pipeline. The lower ends of the fixed pipes are fixedly connected with a plurality of spray pipes. The lower ends of the spray pipes penetrate into the inner cavity of the flue gas pipeline and are fixedly connected with the inner bottom wall of the flue gas pipeline. The outer surface of the flue gas pipeline is fixedly connected with a nozzle. A spray pipe is arranged between the two fixed pipes. The outer surface of the spray pipe is fixedly connected with a plurality of shunt pipes respectively corresponding to the plurality of spray pipes. The two ends of the two shunt pipes away from each other are respectively fixedly connected with the two fixed pipes. A one-way electric valve one is fixedly installed on the outer surface of the plurality of shunt pipes. The rear end of the flue gas pipeline is fixedly connected with a plurality of air inlet pipes. A one-way electric valve two is fixedly installed on the outer ring of the air inlet pipes. A drainage groove is dug on the inner bottom wall of the flue gas pipeline. The lower end of the flue gas pipeline is fixedly connected with a drain pipe.

[0006] In the above particulate matter treatment device in a flue gas pipeline, the existing pipeline is directly utilized, saving the amount of steel for ground towers, the installation cost, and the cost of ground water tank construction, etc. It not only achieves the same particulate matter treatment effect but also effectively solves the problem that the existing site is narrow and not convenient for installing environmental protection equipment, and also reduces the cost investment for enterprises.

[0007] As a further improvement of the present application, the number of nozzles is an even number, and two nozzles form a spraying assembly. The spray heads on the surfaces of the two nozzles in the spraying assembly are mirror-image distributed.

[0008] As a further improvement of the present application, multiple intake pipes and multiple spraying assemblies are distributed at intervals. Both the one-way electric valve one and the one-way electric valve two are signal-connected to an external controller.

[0009] As a further improvement of the present application, the drainage trough is arc-shaped and is located between two fixed pipes.

[0010] As another improvement of the present application, the fixed pipe, the spraying pipe, the shunt pipe, the nozzle and the spray head are interconnected, and the drainage trough is connected to the drain pipe.

[0011] As another improvement of the present application, a water storage tank is provided at the lower end of the flue gas pipe. A filter is fixedly connected to the inner top wall of the water storage tank. The lower end of the drain pipe fixedly penetrates through the water storage tank and is fixedly connected to the filter. A water pump is provided on the left side of the water storage tank.

[0012] In summary, in the actual application process, the intake pipe is connected to the existing flue gas pipe. The flue gas dust enters the flue gas pipe through the intake pipe. The one-way electric valve one on the shunt pipe corresponding to the intake pipe is activated. The fixed pipe conveys water through the shunt pipe into the nozzle, and then it is sprayed out by the spray head. The two spray heads spray water relatively to form a water curtain. The flue gas passes through the water curtain, and the dust contained therein is washed off by the water flow, thereby performing dust removal treatment on the flue gas, realizing the function of remotely controlling and adjusting the spray water volume, that is, meeting the removal effect of flue gas dust, and also being able to adjust the water volume in a timely manner to achieve the purpose of saving water. It directly utilizes the existing pipes, saves the amount of steel for the ground tower body, the installation cost, and the cost of building the ground water tank, etc. It not only achieves the treatment effect of the same particulate matter, but also effectively solves the problem that the existing site is narrow and inconvenient for installing environmental protection equipment, and also reduces the cost investment for the enterprise.

[0022] The following will describe in detail the two embodiments of the present application with reference to the accompanying drawings.

[0023] The first embodiment:

[0024] Figure 1 , Figure 2 , Figure 3 and Figure 4 show: A particulate matter treatment device in a flue gas pipeline, including two fixed pipes 2 installed on the top of the flue gas pipeline 1. The lower ends of the fixed pipes 2 are fixedly connected with a plurality of spray pipes 3. The lower ends of the spray pipes 3 penetrate to the inner cavity of the flue gas pipeline 1 and are fixedly connected with the inner bottom wall of the flue gas pipeline 1. The outer surface of the flue gas pipeline 1 is fixedly connected with spray heads 4. The rear end of the flue gas pipeline 1 is fixedly connected with a plurality of intake pipes 8. A one-way electric valve two 9 is fixedly installed on the outer ring of the intake pipe 8. Those skilled in the art can select a suitable model of the one-way electric valve two 9 according to actual needs. For example: D341X-10C. A drain tank 10 is dug on the inner bottom wall of the flue gas pipeline 1. The lower end of the flue gas pipeline 1 is fixedly connected with a drain pipe 11. The plurality of intake pipes 8 and the plurality of spray components are arranged at intervals. Both the one-way electric valve one 7 and the one-way electric valve two 9 are signal-connected to an external controller. Those skilled in the art can select a suitable model of the controller according to actual needs. For example: LD-B10-10E. By discharging flue gas at different positions through different intake pipes 8, the corresponding one-way electric valve one 7 is started, realizing the function of remotely controlling and adjusting the spray water volume, that is, meeting the removal effect of flue gas dust and also being able to adjust the water volume in a timely manner to achieve the purpose of saving water.

[0025] Figure 5It shows that: a spray pipe 5 is arranged between two fixed pipes 2. A plurality of flow dividing pipes 6 respectively corresponding to a plurality of spray pipes 3 are fixedly connected to the outer surface of the spray pipe 5. The two ends of the two flow dividing pipes 6 away from each other are respectively fixedly connected to the two fixed pipes 2. A one-way electric valve 7 is fixedly installed on the outer surface of the plurality of flow dividing pipes 6. The fixed pipe 2, the spray pipe 5, the flow dividing pipe 6, the spray pipe 3 and the nozzle 4 are interconnected with each other. The drainage trough 10 is communicated with the drain pipe 11. The number of the spray pipes 3 is an even number. Two spray pipes 3 form a spray component. The nozzles 4 on the surfaces of the two spray pipes 3 in the spray component are mirror-image distributed. The plurality of nozzles 4 are close to each other. The nozzles 4 in the spray component spray relatively, thereby forming a water curtain, which is not convenient for treating the dust in the flue gas.

[0026] During use, the air inlet pipe 8 is connected to the existing flue gas pipe 1. The flue gas dust enters the flue gas pipe 1 through the air inlet pipe 8. The one-way electric valve 7 on the flow dividing pipe 6 corresponding to the air inlet pipe 8 is started. The fixed pipe 2 conveys water to the spray pipe 3 through the flow dividing pipe 6, and then is sprayed out by the nozzle 4. The two nozzles 4 spray water relatively to form a water curtain. The flue gas passes through the water curtain, and the dust contained therein is washed off by the water flow, thereby performing dust reduction treatment on the flue gas, realizing the function of remotely controlling and adjusting the spray water volume, that is, meeting the removal effect of the flue gas dust, and also being able to adjust the water volume in a timely manner to achieve the purpose of saving water. The existing pipes are directly utilized, saving the amount of steel for the ground tower body, the installation cost, and the cost of constructing the ground water tank, etc. Not only the treatment effect of the same particulate matter is achieved, but also the problem that it is not convenient to install environmental protection equipment in the existing narrow site can be effectively solved, and the cost input of the enterprise is also reduced.

[0027] The second implementation mode:

[0028] On the basis of the first implementation mode, this implementation mode adds a water storage tank 12, a filter 13, a water pump 14 and a circulation pipe 15, and the rest is the same as the first implementation mode.

[0029] Figure 6 and Figure 7 It shows that: a water storage tank 12 is arranged at the lower end of the flue gas pipe 1. A filter 13 is fixedly connected to the inner top wall of the water storage tank 12. Those skilled in the art can select a suitable model of the filter 13 according to actual needs. For example: SG-10000. The lower end of the drain pipe 11 fixedly penetrates the water storage tank 12 and is fixedly connected to the filter 13. A water pump 14 is arranged on the left side of the water storage tank 12. Those skilled in the art can select a suitable model of the water pump 14 according to actual needs. For example: XBD7.6 / 5W. A suction pipe is fixedly connected between the water inlet of the water pump 14 and the water storage tank 12. The water outlet of the water pump 14 is fixedly connected to a circulation pipe 15. The end of the circulation pipe 15 away from the water pump 14 is fixedly connected to the spray pipe 5.

[0030] During use, the sewage containing dust particles in the flue gas pipeline 1 enters the water storage tank 12 through the drain pipe 11, is filtered by the filter 13, and then the water pump 14 transports the water in the water storage tank 12 to the spray pipe 5 for reuse, thus effectively saving water resources.

[0031] Combined with the current actual needs, the above implementation manner adopted in this application, the protection scope is not limited to this. Within the scope of knowledge possessed by those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of this utility model.
