[0002] Industrial wastewater includes production wastewater, industrial sewage, and cooling water. It refers to the wastewater and waste liquid (hereinafter collectively referred to as waste liquid) generated during industrial production. It contains industrial production materials, intermediate products, by-products, and pollutants generated during the production process that are lost with the water. Industrial waste liquid is diverse and complex in composition.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] Please see Figure 1 This utility model provides a waste liquid conveying and incineration device, including an incinerator 1, a feed pipe 3, a feed pump 5, a fluid control component, and a compressed air pipe. The incinerator 1 is equipped with a waste liquid spray gun 2, with the nozzle of the waste liquid spray gun 2 facing the furnace cavity of the incinerator 1. One end of the feed pipe 3 is connected to a waste liquid storage tank 4, and the other end is connected to the waste liquid spray gun 2. The feed pump 5 is installed on the feed pipe 3 and is used to transport wastewater in the waste liquid storage tank 4 to the waste liquid spray gun 2. The fluid control component is set on the feed pipe 3 and is located between the feed pump 5 and the waste liquid spray gun 2. The compressed air pipe includes a main pipe 7, a first branch pipe 8, and a second branch pipe 9. The main pipe 7 is used to transport compressed air, the first branch pipe 8 is used to connect the main pipe 7 and the waste liquid spray gun 2, and the second branch pipe 9 is used to connect the main pipe 7 and the feed pipe 3. Both the first branch pipe 8 and the second branch pipe 9 are equipped with gas control valve components.

[0024] Specifically, the waste liquid feed pipe 3 is inserted into the waste liquid storage tank 4 containing waste liquid. Then, the feed pump 5 is started and compressed air is supplied through the compressed air pipe. At this time, the waste liquid is drawn by the feed pump 5 and flows from the waste liquid feed pipe to the waste liquid spray gun 2. The compressed air inside the compressed air pipe flows into the spray gun nozzle to atomize the waste liquid. Finally, the atomized waste liquid is sprayed into the incinerator 1, thereby achieving complete combustion of the waste liquid.

[0025] The fluid control assembly includes a first pressure gauge 10, a front manual valve 11, a first pneumatic quick-closing ball valve 12, a front manual ball valve 13, a Y-type filter 14, a pneumatic flow regulating valve 15, a flow meter 17, a rear manual ball valve 18, and a second pressure gauge 19, all installed sequentially along the direction of waste liquid delivery by the feed pump 5.

[0026] The feed pipe 3 and the waste liquid spray gun 2 are connected by a first metal hose 16. One end of the first metal hose 16 is connected to the feed pipe 3, and the other end is connected to the front inlet of the waste liquid spray gun 2. Specifically, the design of the first metal hose 16 facilitates the movement of the waste liquid spray gun 2 and makes it easier to maintain and replace it.

[0027] It should be noted that the first pressure gauge 10 is used to monitor the waste liquid pressure at the inlet of the feed pipe 3 in real time; the manual valve is installed as a physical isolation device during system maintenance; the main pneumatic quick-closing ball valve can complete the locking in a short time; the front manual ball valve 13 is used to manually isolate and close the feed pipe 3 for convenient maintenance; the Y-type filter 14 is used to intercept solid impurities; the pneumatic flow regulating valve 15 and the flow meter 17 form a closed-loop control to monitor the waste liquid flow in real time. Based on this, when the waste liquid is transported and burned, the flow of the waste liquid is controlled by adjusting the opening of the pneumatic flow regulating valve 15 to ensure the stability of the working conditions; the rear manual ball valve 18 is used to manually isolate and close the feed pipe 3 for convenient maintenance; the second pressure gauge 19 can monitor the pressure fluctuation of the filtered waste liquid in the feed pipe 3.

[0028] The feed pipe 3 is connected to a return pipe 20. One end of the return pipe 20 is located between the front manual ball valve 13 and the main pneumatic ball valve, and the other end is located between the rear manual ball valve 18 and the second pressure gauge 19. A first manual ball valve 21 is installed on the return pipe 20. This allows for the return of waste liquid.

[0029] A second metal hose 22 is provided between the first branch pipe 8 and the waste liquid spray gun 2. One end of the second metal hose 22 is connected to the first branch pipe 8, and the other end is connected to the rear inlet of the waste liquid spray gun 2. This facilitates the movement of the waste liquid spray gun 2.

[0030] The gas control valve assembly includes a second manual ball valve 23, a second pneumatic quick-closing ball valve 24, and a check valve 25. It should be noted that the second manual ball valve 23, the second pneumatic quick-closing ball valve 24, and the check valve 25 of the gas control valve assembly on the first branch pipe 8 are arranged sequentially along the compressed air delivery direction. Further, it should be noted that the second manual ball valve 23, the second pneumatic quick-closing ball valve 24, and the check valve 25 of the gas control valve assembly on the second branch pipe 9 are arranged sequentially along the compressed air delivery direction. One end of the main pipeline 7 is connected to an air compressor.

[0031] It should be noted that one end of the second branch pipe 9 is connected to the main pipe 7, and the other end is connected to the feed pipe 3. The second branch pipe 9 is connected at one end of the feed pipe 3 between the second pressure gauge 19 and the first metal hose 16.

[0032] First, the valve of the second manual ball valve 23 on the second branch pipe 9 is closed. When the air compressor is working normally, the compressed air it delivers is delivered from the main pipe 7 to the first branch pipe 8 and flows into the waste liquid spray gun 2. At this time, the waste liquid in the waste liquid spray gun 2 can be atomized by compressed air to achieve a better incineration effect.

[0033] Furthermore, if the second pressure gauge 19 shows an abnormal pressure during waste liquid combustion, the valve of the second manual ball valve 23 on the second branch pipe 9 can be opened. The compressed air delivered by the air compressor will be delivered from the main pipe 7 to the second branch pipe 9 and flow into the feed pipe 3. This can achieve backflushing when there is a blockage in the feed pipe 3, so as to avoid the feed pipe 3 from becoming blocked.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
