[0002] Ceramic heating equipment is used in the ceramic heating process to heat and form. During and after the forming process, a large amount of heat will be released. Some equipment will recycle the energy, but the traditional heat recovery system only sets up heat absorption equipment on the periphery of the air pipe. The contact area and heat absorption capacity are average, which affects the heat recovery ability.

[0003] A Chinese patent document (authorization publication number CN210374663U) describes an environmentally friendly ceramic kiln waste heat recovery device. This device effectively increases the contact area between the kiln's waste heat and water, improving heat conversion efficiency and the reuse rate of waste heat. This device also cleans exhaust gases, enhances the device's environmental impact, versatility, and efficiency. However, the device only incorporates heat absorption equipment around the periphery of the gas pipe, resulting in limited surface area and heat absorption capacity, which impacts heat recovery capabilities.

[0030] The connection method can be bonding, welding, bolt connection, etc., which shall be based on actual needs.

[0031] In order to recycle heat and improve the heat recovery capacity, a heat recovery system as shown in Figures 1 to 6 includes an inclined intake pipe 1 connected to the ceramic heating equipment, the side connecting plate 11 is connected to the ceramic heating equipment, and the intake pipe 1 is connected to the outlet pipe of the ceramic heating equipment. The ceramic heating equipment is configured as a large-scale device. The intake pipe 1 is connected to a processing box 2 for treating air. An assembly barrel 3 filled with clean water for heat recovery is provided above the processing box 2. The top of the processing box 2 is connected to a vertically arranged ventilation pipe 4; the inner cavity of the assembly barrel 3 is provided with a plurality of heat exchange pipes 5, and the end of the upper half of the ventilation pipe 4 passes through the assembly barrel 3 and extends to the inner cavity of the assembly barrel 3. The ventilation pipe 4 is connected to a plurality of heat exchange pipes through a multi-way pipe fitting. The tubes 5 are connected, and the multi-way pipe fittings are not subject to the diagram. It is sufficient to ensure that a large tube is connected to multiple thin tubes. The air enters the heat exchange tube 5 through the ventilation tube 4, and then conducts the heat out. The heat is conducted through the heat exchange tube 5 and the clean water in the assembly barrel 3. A reaction box 6 containing a reaction liquid for treating odor is provided on one side of the assembly barrel 3. The reaction liquid is set to be a specific liquid that can react with the ceramic heating odor, which is a prior art. The side of the upper half of the reaction box 6 is connected to an L-shaped connecting tube 7, and one side end of the connecting tube 7 passes through the assembly barrel 3 and extends to the inner cavity of the assembly barrel 3. The connecting tube 7 is connected to multiple heat exchange tubes 5 through multi-way pipe fittings, and a fan 8 for exhaust is embedded in the side of the reaction box 6 away from the connecting tube 7.

[0032] In order to provide stable support and connection, the assembly barrel 3 is welded and fixed to the reaction box 6 through multiple horizontal auxiliary rods 9, and the assembly barrel 3 is welded and fixed to the processing box 2 through multiple vertical auxiliary rods 10. The bottom end of the processing box 2 is welded with multiple diagonal support plates, and the bottom end of the diagonal support plate is welded with an L-shaped side connecting plate 11 for connecting to the ceramic heating equipment. The sides of the reaction box 6, the sides of the processing box 2 and the sides of the assembly barrel 3 are all embedded with perspective windows to facilitate observation of the situation from the outside.

[0033] In order to deodorize the air, an assembly plate 12 is installed on the horizontal inner wall above the reaction box 6. The bottom end of the assembly plate 12 is connected to a plurality of equally spaced water spray heads 13. The top of the reaction box 6 is connected to a water pump 14. The water pump 14 is connected to the lower half of the reaction box 6 through a water suction pipe 15. The water pump 14 is also connected to a water outlet pipe 16, and the water outlet pipe 16 passes through the reaction box 6 and is connected to the plurality of water spray heads 13 through multi-way pipe fittings. The air continues to flow and enters the reaction box 6 through the connecting pipe 7. The water pump 14 sprays the reaction liquid from the water spray head 13. The air is treated by the water curtain formed by the water spray head 13 and finally flows out from the fan 8.

[0034] In order to filter the air and clean the filter, the inner wall of the processing box 2 is detachably connected with an inclined filter frame 17, and the side of the filter frame 17 is detachably connected with a filter for filtering the air. The inner wall of the processing box 2 is connected with two inclined linear motors 18 adapted to the filter frame 17 by bolts, and a brush 19 for cleaning the filter is connected between the moving parts of the two linear motors 18. The fan 8 can exhaust air to assist the air in the ceramic heating equipment to be introduced into the intake pipe 1. When passing through the processing box 2, the air is filtered by the filter. During this process, the linear motor 18 drives the brush 19 to clean the filter back and forth. An inspection channel is opened on the side of the processing box 2, and the inner wall of the inspection channel is connected to an inspection door 20 by a hinge. The inspection door 20 is fixed to the processing box 2 by a lock.

[0035] In order to add and drain water, the top of the assembly barrel 3 is connected to a liquid inlet pipe 21 with a threaded cover, and clean water is introduced into the assembly barrel 3 by means of the liquid inlet pipe 21. The bottom end of the assembly barrel 3 is connected to a liquid discharge pipe 22 with a solenoid valve. When water is needed, the solenoid valve is opened to allow the liquid discharge pipe 22 to discharge liquid. A thermometer 23 is installed on the side of the assembly barrel 3, and the measuring part of the thermometer 23 passes through the assembly barrel 3 and extends to the inner cavity of the assembly barrel 3. The temperature of the clean water is known from the thermometer 23. The outer periphery of the assembly barrel 3 and the outer periphery of the processing box 2 are coated with thermal insulation coating.

[0036] How it works

[0037] The heat recovery and utilization system uses the liquid inlet pipe 21 to introduce clean water into the assembly barrel 3, connects the side connecting plate 11 with the ceramic heating equipment, connects the intake pipe 1 with the exhaust pipe of the ceramic heating equipment, and then turns on the linear motor 18, the water pump 14 and the fan 8. The fan 8 can exhaust air to assist the air in the ceramic heating equipment to be introduced into the intake pipe 1. When passing through the processing box 2, the air is filtered by the filter. During this process, the linear motor 18 drives the brush 19 to clean the filter back and forth. The air enters the heat exchange pipe 5 through the ventilation pipe 4, and then the heat is transferred to the clean water in the assembly barrel 3 through the heat exchange pipe 5. The air continues to flow and enters the reaction box 6 through the connecting pipe 7. The water pump 14 sprays the reaction liquid from the water spray head 13. The air is treated by the water curtain formed by the water spray head 13 and finally flows out from the fan 8.
