Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

[0033] Combination Figure 1 The utility model is a waste heat recovery device for thermal power engineering, comprising an evaporation chamber 3, a thermal chamber 5 is penetrated and fixedly connected to the lower part of the outer wall of the evaporation chamber 3, a sealing cover 1 is penetrated and fixedly connected to the top of the evaporation chamber 3, a condensation cone 15 is fixedly connected to the middle part of the bottom of the sealing cover 1, a fixed bracket 2 is fixedly connected to the upper part of the rear side of the evaporation chamber 3, a water inlet pipe 7 is penetrated and fixedly connected to the middle part of the right side of the evaporation chamber 3, a drain pipe 4 is penetrated and fixedly connected to the middle part of the left side of the evaporation chamber 3, a collecting box 16 is fixedly connected to the right end of the drain pipe 4, and the collecting box 16 corresponds to the condensation cone 15, a sewage outlet 9 is fixedly connected to the bottom of the evaporation chamber 3, a valve 10 is penetrated and fixedly connected to the lower end of the sewage outlet 9, and a gas pipe 6 is penetrated and fixedly connected to the lower left side and the upper right side of the thermal chamber 5.

[0034] The condensation cone 15 is conical in shape, larger at the top and smaller at the bottom, which is convenient for condensation and collection of moisture. The thermal chamber 5 is composed of an outer shell that cooperates with the outer shell of the evaporation chamber 3. Compared with heating at the bottom of the evaporation chamber, this method increases the heating area and improves the heating efficiency.

[0035] Combination Figure 2 , Figure 4-Figure 6A water tank 14 is passed through and fixedly connected to the top of the fixed bracket 2, a cooling pipe 21 is passed through and fixedly connected to the inside of the condensing cone 15, and the right port of the cooling pipe 21 passes through the water tank 14, a liquid pump 11 is fixedly connected to the left side of the top of the water tank 14, and the output end of the liquid pump 11 passes through and fixedly connected to the left port of the cooling pipe 21, a heat dissipation mechanism is passed through and arranged on the lower rear side of the water tank 14, and the heat dissipation mechanism includes a heat dissipation fin 13, a heat conducting plate 22 is passed through and fixedly connected to the middle of the front side of the heat dissipation fin 13, two heat dissipation fans 12 are fixedly connected to the rear side of the heat dissipation fin 13, the heat conducting plate 22 passes through and fixedly connected to the water tank 14, and the heat dissipation fin 13 passes through and fixedly connected to the water tank 14.

[0036] The cooling pipe 21 spirals upward in a cone shape and is located close to the outer edge of the condensation cone 15. The cooling water in the water tank 14 is pumped into the left port of the cooling pipe 21 by the liquid pump 11. The cooling water flows upward along the pipe spiral and flows back into the water tank 14 through the right port. The heat in the refluxed heated cooling water is extracted through the heat conduction plate 22, and the heat dissipation is accelerated through the heat dissipation fins 13 and the heat dissipation fan 12, so that the temperature of the outer side of the condensation cone 15 is maintained in a constant range, thereby improving the condensation efficiency.

[0037] Combination Figure 3 A cleaning assembly is provided at the lower part of the evaporation chamber 3, and the cleaning assembly includes a motor 8. The output end of the motor 8 passes through and is fixedly connected with a first bevel gear 18, and the lower side of the first bevel gear 18 is meshedly connected with a second bevel gear 19. A cleaning leaf 17 is fixedly connected to the middle part of the bottom of the second bevel gear 19, and the lower end of the cleaning leaf 17 passes through and is rotatably connected with a mounting seat 20, and the mounting seat 20 passes through and is fixedly connected to the sewage outlet 9. The motor 8 is fixedly connected to the evaporation chamber 3, and the output end of the motor 8 passes through the evaporation chamber 3.

[0038] The evaporation chamber 3 is connected to the area of ​​the thermal chamber 5. Since heat is conducted to the wastewater inside the evaporation chamber 3 through this area, scale is easily generated and adheres to this area. The cleaning leaves 17 are driven by the motor 8 to scrape off the scale, keeping the inner wall of the evaporation chamber 3 clean and improving the heating efficiency. When the cleaning leaves 17 rotate, they can drive the wastewater to move, so that the wastewater can be fully mixed and heated.

[0039] Working principle: first, a certain amount of waste water is injected into the evaporation chamber 3 through the water inlet pipe 7, and then the thermal exhaust gas is transported to the thermal chamber 5 through the right air pipe 6. The waste water in the evaporation chamber 3 is heated by the thermal exhaust gas, and the water in the waste water evaporates and moves upward and contacts the condensation cone 15. At this time, the liquid pump 11 is turned on to pump the cooling water in the water storage tank 14 into the cooling pipe 21, so that the water vapor condenses into water droplets on the surface of the condensation cone 15, and flows to the lower tip of the condensation cone 15 due to its own gravity, and then drips into the collection box 16, and then is discharged to the outside along the drain pipe 4 and collected. When scale adheres to the inner wall of the evaporation chamber 3 and reduces the heating effect, the first bevel gear 18 is driven to rotate by turning on the motor 8, and then the cleaning blade 17 is driven to rotate through the second bevel gear 19 to scrape off the scale attached to the inner wall of the evaporation chamber 3. The scale is precipitated at the bottom of the sewage outlet 9 due to gravity, and then the scale is discharged by opening the valve 10.
