Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of waste gas treatment, in particular to a waste gas treatment device for the production of refractory materials in a hazardous waste kiln furnace. Background Technique
[0002] The hazardous waste kiln furnace is the main incineration and treatment facility for solid and liquid hazardous wastes. In order to improve the fire resistance of the hazardous waste kiln furnace during the incineration of hazardous wastes, a large number of refractory materials need to be fixed in the hazardous waste kiln furnace to improve the overall fire resistance of the hazardous waste kiln furnace. When producing refractory materials, a kiln furnace is required. In order to raise the temperature inside the kiln furnace, fuels such as bituminous coal and coke fines need to be burned. During the combustion of bituminous coal in the kiln furnace, soot and many harmful gases will be generated. Therefore, a corresponding waste gas treatment device needs to be used to treat these waste gases before discharging them to the outside.
[0003] After retrieval, the patent with the Chinese patent application number CN202220874688.6 discloses a waste gas treatment device for the production of refractory materials, including a reaction box and a waste gas pipe. On the left and right sides of the inner wall of the reaction box, limiting plates are fixedly connected at equal distances along the vertical plane. However, since the above technical solution does not provide a corresponding mechanism for quickly cooling the high-temperature waste gas discharged from the kiln furnace, there is still a problem that the temperature of the waste gas after filtration treatment is still relatively high, resulting in the high-temperature waste gas after discharge being likely to affect the surrounding temperature environment.

A plurality of heat exchange tubes 4 are arranged on the outer wall of one side of the intake pipe 1. A circulating liquid guide pipe 5 is fixed on the outer wall of the heat exchange tube 4. The two ends of the circulating liquid guide pipe 5 are respectively connected to a first connection box 12. A water outlet pipe 11 and a water inlet 13 are respectively fixed on the outer wall of the first connection box 12. A cooling box 7 is fixed on the outer wall of one side of the heat exchange tube 4. A plurality of rectangular through grooves are opened on the top outer wall of the cooling box 7. A plurality of water guide joints 10 are fixed on the inner walls of the rectangular through grooves. A water spraying plate 19 is fixed on the outer wall of the water guide joint 10. The outer wall of the water guide joint 10 is connected to a third connection box 18 through a pipeline. A circulating pump 17 is fixed on the outer wall of the cooling box 7. The third connection box 18 is connected to the circulating pump 17 through a pipeline;
[0027] The outer wall of the circulation pump 17 is connected to a second connection box 16 through a pipeline. A filter box 15 is fixed to the outer wall of one side of the second connection box 16, and a plurality of collection frames 14 are arranged on the outer wall of one side of the filter box 15;
[0028] A plurality of drain ports are opened on the bottom outer wall of the cooling box 7, and the collection frame 14 is inserted into the inner wall of the drain hole;
[0029] A connector 2 is arranged on the outer wall of the intake pipe 1;

[0031] A plurality of filter meshes 24 are fixed to the inner wall of the filter box 15;
[0032] A plurality of heat dissipation plates 6 are arranged on the outer wall of the cooling box 7;
[0033] The staff connects the connector 2 with the pipeline for discharging waste gas through a pipeline, and then passes the high-temperature waste gas to be treated into the plurality of heat exchange tubes 4 on one side through the connector 2. Then, clear water is passed into the circulating liquid guide pipe 5 through a water delivery pipeline. At this time, the water flowing through the circulating liquid guide pipe 5 will absorb heat from the high-temperature waste gas flowing through the heat exchange tubes 4, thereby quickly reducing the temperature of the waste gas. At the same time, the clear water after absorbing heat will become hot, so as to convey hot water out through the water outlet pipe 11, making use of the heat energy in the waste gas and improving the heat dissipation efficiency of the waste gas;

[0037] Working principle: The staff connects the connector 2 to the exhaust gas pipeline through the pipeline, and then passes the high-temperature exhaust gas to be treated into the multiple heat exchange tubes 4 on one side through the connector 2. Subsequently, clean water is passed into the circulating liquid guide pipe 5 through the water supply pipeline. At this time, the water flowing through the circulating liquid guide pipe 5 will absorb heat from the high-temperature exhaust gas flowing through the heat exchange tubes 4, thereby rapidly reducing the exhaust gas temperature. At the same time, the clean water after absorbing heat will become hot and be transported outwards through the water outlet pipe 11 as hot water.
[0038] Subsequently, when the exhaust gas passes through the cooling box 7, the circulating pump 17 will fill the corresponding water guide joints 10 with cooling water through the third connection box 18, and then spray it into the cooling box 7 through the spray plate 19 installed at the bottom of the water guide joint 10 to spray and cool and remove dust from the exhaust gas flowing through the cooling box 7. The water with dust and debris will flow into the filter box 15 through the collection frame 14. The dust and sludge in the water flow will be filtered by the filter net 24 and then continue to be filled into the water guide joint 10 by the circulating pump 17, so as to continuously remove dust and absorb heat from the exhaust gas through the circulating water. The exhaust gas after cooling and dust removal enters the activated carbon filter 9 through the exhaust pipe 8 for another purification and filtration, and then is discharged into the external environment.
