Description

Technical Field

[0001] The utility model relates to the technical field of incinerators, in particular to a regenerative incinerator for incinerating waste liquid. Background Art

[0002] In equipment for treating industrial wastewater, most of them filter the wastewater. After the wastewater only contains small particles and flammable components, an incinerator is used to incinerate the wastewater. After the wastewater is incinerated, carbon dioxide, water and some inorganic salts are produced. Before discharging the incinerated gas, an exhaust gas needs to be added through an exhaust pipe, and the incinerated matter is discharged along the exhaust direction. Before the incinerated gas is discharged, some inorganic salt components need to be filtered out to avoid affecting the ecological environment. The precipitate formed on the filter screen is buried or recovered by reduction. Specifically, a filter membrane is added at the exhaust pipe orifice of the incinerator to filter the exhaust gas. The gas flow direction in the furnace body is constant. Under the blowing of the exhaust gas, the exhaust gas in the filter membrane flows in a fixed direction, resulting in the area of the filter membrane along the blowing direction being easily blocked, affecting the filtering efficiency of the exhaust gas. Summary of the Utility Model

The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention, and should not be construed as a limitation of the present invention. On the contrary, the embodiments of the present invention include all changes, modifications and equivalents falling within the spirit and scope of the appended claims.

[0023] As Figures 1 to 6 shown, this embodiment provides a regenerative incinerator for incinerating waste liquid, including a furnace body 10, an incineration chamber 20 arranged in the furnace body 10, a pipeline device 30 installed on the furnace body 10, and a filtration device 40 arranged in the pipeline device 30. High-temperature gas can be injected into the furnace body 10 through the pipeline device 30 to maintain the temperature of the waste liquid being incinerated. The waste liquid can also be sprayed into the incineration chamber 20 through the pipeline device 30. After atomization, the waste liquid can be incinerated more quickly. The pipeline device 30 can also evacuate the gas formed by the incinerated waste liquid. Before the gas is evacuated, the filtration device 40 in the pipeline device 30 can filter the gas to avoid the impact of the exhausted gas on the environment.

[0024] As Figure 1 shown, the furnace body 10 is generally of a through structure. The incineration chamber 20 is fixed above the furnace body 10. The furnace body 10 provides heat for the incineration chamber 20. A heat storage body is installed in the incineration chamber 20, and the heat storage body can retain heat to maintain the temperature in the incineration chamber 20 at a level capable of incinerating waste liquid all the time. By spraying and injecting the waste liquid to be incinerated into the incineration chamber 20, under the catalysis of the high temperature in the incineration chamber, the waste liquid is oxidized to form water, carbon dioxide and inorganic salts.

[0025] The pipeline device 30 includes a heat supply pipeline 310 connecting each furnace body 10, a feeding pipeline 320 connecting each incineration chamber 20, and an exhaust pipeline 330 arranged in the gas discharge direction.

[0026] A heating pipeline 310 is provided with heating branch pipes 311 corresponding to the furnace body 10. The heating branch pipes 311 communicate with the inside of the furnace body 10. The end of the heating pipeline 310 communicates with a heat source. The heating pipeline 310 obtains high-temperature gas from the heat source. The high-temperature gas is discharged into the furnace body 10 through the heating branch pipes 311. The high-temperature gas in the furnace body 10 enters the incineration chamber 20. In the incineration chamber 20, the heat storage body is heated by the high-temperature gas to maintain the heating temperature in the incineration chamber 20. A plurality of material distribution pipes 321 are connected to the feeding pipeline 320. The material distribution pipes 321 are arranged corresponding to the incineration chamber 20. The material distribution pipes 321 communicate with the inside of the incineration chamber 20. Waste liquid can be injected into the incineration chamber 20 through the feeding pipeline 320 and the material distribution pipes 321. The waste liquid in the incineration chamber 20 can be catalytically decomposed at high temperature. An evacuation pipeline 330 is installed on the incineration chamber 20. There are a plurality of evacuation pipelines 330. The plurality of evacuation pipelines 330 communicate with an evacuation main pipe 331. The evacuation main pipe 331 and the evacuation pipelines 330 form a cross-shaped four-way pipe structure. Carbon dioxide, water and inorganic salt components formed by incineration in the incineration chamber 20 enter the evacuation main pipe 331 through the evacuation pipelines 330. The evacuation main pipe 331 is then communicated with a gas source for auxiliary evacuation. Under the blowing of the auxiliary gas in the evacuation main pipe 331, the exhaust gas can be discharged to the outside.

[0027] As Figures 2 to 6 shown, the filtering device 40 includes a cover plate 410 rotatably covering the pipe orifice of the evacuation pipeline 330, a permeable membrane 420 fixed on the cover plate 410, a rotating frame 430 fixedly installed at the central part of the cover plate 410, and a bearing base 440 fixed on the pipe wall of the evacuation pipeline 330.

[0028] As Figures 3 to 6As shown, the cover plate 410 includes a cover-shaped ring plate 411 rotatably covered on the pipe opening of the emptying pipe 330 and a clamping cover plate 412 clamped at the center of the cover-shaped ring plate 411. The edge of the clamping cover plate 412 is provided with a pressing protrusion 413, and the edge of the pressing protrusion 413 is also provided with a connecting protrusion 414. The pressing protrusion 413 is embedded and pressed on the edge of the clamping cover plate 412, and the connecting protrusion 414 is fixedly installed on the cover-shaped ring plate 411. One side of the permeable membrane 420 is pressed on the clamping cover plate 412 by the pressing protrusion 413. When the connection strength between the connecting protrusion 414 and the clamping cover plate 412 is tightened, the pressing protrusion 413 can press and fix the permeable membrane 420. The rotating frame 430 is fixedly mounted at the middle position of the clamping cover plate 412, that is, the rotating frame 430 is arranged at the middle position of the permeable membrane 420, and the end of the rotating frame 430 away from the clamping cover plate 412 clamps the side of the permeable membrane 420, and the side wall of the rotating frame 430 also abuts against the bearing base 440. Preferably, the rotating frame 430 includes a rotating rod 431 fixed at the center position of the clamping cover plate 412, a support rod 432 fixedly mounted at the end of the rotating rod 431, and a clamping ring block 433 mounted on the support rod 432. The rotating rod 431 is arranged parallel to the axis of the emptying pipe 330, and the support rod 432 is fixed to the end of the rotating rod 431 away from the clamping cover plate 412, and the clamping ring block 433 can clamp and fix the permeable membrane 420, and the clamping ring block 433 can be slidably mounted on the bearing base 440.

[0029] When the above-mentioned regenerative incinerator is in use, firstly, the heat delivery pipe 310 is used to inject high-temperature gas into the furnace body 10, and the high-temperature gas is heated in the incineration chamber 20. The heat storage body in the incineration chamber 20 cooperates with the high-temperature gas to maintain the temperature in the incineration chamber at a level that can incinerate and decompose the wastewater. Then, the wastewater to be burned is injected into the furnace body 10 through the feeding pipe 320. The wastewater is burned and decomposed into carbon dioxide, water and some inorganic salts in the incineration chamber 20. The incineration materials in the incineration chamber 20 are collected and discharged uniformly through the discharge pipe 330. Specifically, the incineration in the incineration chamber 20 After being filtered through the permeable membrane 420, the product enters the exhaust pipe 330, and the auxiliary exhaust gas flows in the exhaust main pipe 331. Under the blowing of the auxiliary exhaust gas, the gas to be exhausted in the exhaust pipe 330 is filtered through the permeable membrane 420 and enters the exhaust main pipe 331. When the carbon dioxide and water content in the exhaust main pipe 331 decreases, the permeable membrane 420 can be driven to rotate by rotating the cover plate 410 to change the angle of the permeable membrane 420 relative to the exhaust gas flow direction, thereby changing the main filtering area on the permeable membrane 420, thereby improving the utilization efficiency of the permeable membrane 420.
