[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] Specific implementation examples are given below.

A water receiving bottle 19 is fixedly connected to the top of the water pipe 18; a steam pipe 15 and a condenser pipe 16 are fixedly connected to the top of the water receiving bottle 19; a preheating bottle 14 is provided at the end of the steam pipe 15 and the condenser pipe 16 away from the water receiving bottle 19; a preheating box 12 is provided outside the multiple preheating bottles 14, and a blower pipe 11 and a heat recovery pipe 13 are fixedly connected to both ends of the preheating box 12; during operation, the operator can connect the exhaust pipe containing heat to the hot air pipe 1, so that the hot air passes through the inside of the heating box 2 and heats the multiple steam bottles 3 by contact. After the multiple steam bottles 3 are heated, the liquid inside evaporates. Steam is generated and then enters the water receiving bottle 19 via the first connecting pipe 4, the second connecting pipe 5, the third connecting pipe 6, the pressure regulating pipe 17, and the water supply pipe 18. The steam then continues through the steam pipe 15 at the top of the water receiving bottle 19 into multiple preheating bottles 14 inside the preheating chamber 12. After the multiple preheating bottles 14 are filled with hot steam, the operator can use a fan to inject cold air into the air blowing pipe 11. This cold air enters the preheating chamber 12 and comes into contact with the multiple preheating bottles 14, heating them up. The operator can then reconnect the heat recovery pipe 13 to the reverse... The heated air is then returned to the reactor via the pressure regulating pipe 17, which balances the internal pressure of the steam bottle 3 and the water receiving bottle 19. The hot steam inside the preheating bottle 14 is liquefied by cooling and can then return to the water receiving bottle 19 via the condenser pipe 16. The hot air inside the heating box 2 heats the steam bottle 3 and is then discharged through the exhaust pipe 7. This step, by setting up the steam bottle 3 and the preheating bottle 14 to recover the heat generated during the production of ceramic fiber filter tubes, solves the problem of heat recovery during production, ensures the dryness of the returned hot air, helps save energy costs, avoids waste, and promotes sustainable development.

[0025] like Figure 1 and Figure 4As shown, a fixing block 20 is provided on the side wall of the water receiving bottle 19, and multiple fixing blocks 20 are set according to the size of the water receiving bottle 19; connecting rods 21 are fixedly connected between the multiple fixing blocks 20, and the connecting rods 21 are arranged in a circumferential array; the top of the top fixing block 20 and the bottom of the bottom fixing block 20 are fixedly connected to a connecting post 22; during operation, the multiple fixing blocks 20 set according to the size of the water receiving bottle 19 are in close contact with the water receiving bottle 19, and the close contact maintains the shape of the water receiving bottle 19, providing the water receiving bottle 19 with The multiple connecting columns 22 located at the top and bottom of the fixing block 20 connect the heating box 2, the water receiving bottle 19, and the preheating box 12, and provide support for the multiple fixing blocks 20 and connecting rods 21. This step maintains the structural stability of the water receiving bottle 19 by setting the fixing blocks 20 and connecting columns 22, and at the same time provides support for the water receiving bottle 19, the preheating box 12 and the internal components of the preheating box 12. This helps to prevent the water receiving bottle 19 from deforming, enhances the stability of the heat recovery equipment, and helps to extend the service life of the equipment.

[0026] like Figure 1 As shown, side beams 9 are fixed to the side walls of the heating box 2 and the preheating box 12, and multiple side beams 9 are correspondingly arranged; support columns 10 are fixed to the ends of the multiple side beams 9, and the multiple support columns 10 are arranged in parallel; a reinforcing outer frame 8 is provided on the side walls of the heating box 2 and the preheating box 12; during operation, the multiple side beams 9 and support columns 10 are set on the side wall of the preheating box 12 away from the heat return pipe 13, and on the side wall of the heating box 2 away from the hot gas pipe 1, away from the ceramic fiber filter tube production equipment. The multiple side beams 9 and support columns 10 work simultaneously to provide support for the heating box 2, the preheating box 12 and their internal components, and maintain the stability of the equipment's center of gravity. The reinforcing outer frame 8 serves to reinforce the heating box 2 and the preheating box 12. This step maintains the stability of the equipment's posture by setting the side beams 9 and support columns 10 at a position away from the ceramic fiber filter tube production equipment, avoiding tilting of the equipment, enhancing the stability of the heat recovery equipment, reducing safety hazards, and ensuring personnel safety.

[0027] like Figure 1 As shown, a temperature measuring instrument is installed on the side wall of the hot gas pipe 1; a temperature measuring instrument is installed on the side wall of the exhaust gas pipe 7; the probes of the temperature measuring instruments are located inside the hot gas pipe 1 and the exhaust gas pipe 7; during operation, the probes of the stable measuring instruments located inside the hot gas pipe 1 and the exhaust gas pipe 7 can display the internal temperature of the hot gas pipe 1 and the exhaust gas pipe 7 on the temperature measuring instruments. The operator can judge the heat recovery status of multiple steam cylinders 3 by observing the temperature difference between the two temperature measuring instruments; this step, by setting temperature measuring instruments on the side walls of the hot gas pipe 1 and the exhaust gas pipe 7 to display the heat recovery status of multiple steam cylinders 3, solves the problem of visualizing the heat recovery status of the equipment, and enhances the flexibility and practicality of the heat recovery equipment.

[0028] like Figure 1 As shown, a pressure measuring instrument is installed on the side wall of the water receiving bottle 19, and the probe of the pressure measuring instrument is located inside the water receiving bottle 19. During operation, the probe of the pressure measuring instrument located inside the water receiving bottle 19 can display the gas pressure inside the water receiving bottle 19 on the pressure measuring instrument. This step, by setting a pressure measuring instrument inside the water receiving bottle 19 to display the gas pressure inside the water receiving bottle 19, thereby displaying the internal gas pressure of the steam bottle 3 and the preheating bottle 14, enhances the flexibility of the equipment, helps to avoid equipment damage caused by excessive gas pressure, and helps to reduce safety hazards.

During operation, multiple sealing blocks 24 can fill the gaps between the heat recovery pipe 13, the air blowing pipe 11, and the preheating box 12 to prevent the leakage of cold air entering the preheating box 12 through the air blowing pipe 11 and to prevent the leakage of hot air inside the heating box 2. This step, by setting multiple sealing blocks 24, prevents gas leakage, thereby ensuring personnel safety, improving the heat recovery rate, and avoiding energy waste.

[0030] like Figure 1 and Figure 4 As shown, a gasket 23 is fixed between the connecting column 22 and the heating box 2; a gasket 23 is fixed between the connecting column 22 and the preheating box 12; during operation, multiple gaskets 23 located at the ends of the connecting column 22 can increase the contact area and fixed area between the connecting column 22 and the heating box 2, and increase the contact area and fixed area between the connecting column 22 and the preheating box 12; this step enhances the stability of the equipment, helps reduce the pressure between components, and extends the service life of the equipment.

[0031] During operation, the operator connects the heat-containing exhaust pipe to the hot air pipe 1, allowing hot air to pass through the heating chamber 2 and heat multiple steam bottles 3 through contact. After being heated, the liquid inside the multiple steam bottles 3 evaporates, forming steam. The steam then flows through the first connecting pipe 4, the second connecting pipe 5, the third connecting pipe 6, the pressure regulating pipe 17, and the water pipe 18 into the water receiving bottle 19, and continues through the steam pipe 15 at the top of the water receiving bottle 19 into multiple preheating bottles 14 inside the preheating chamber 12. Once the multiple preheating bottles 14 are filled with hot steam, the operator can use a blower to pump cold air into the air blowing pipe 11. This cold air, upon entering the preheating chamber 12, will react with the steam inside the preheating chamber 12. The preheating bottle 14 comes into contact with the preheating bottle 14, and the temperature rises through contact with the preheating bottle 14. The operator can reconnect the heat recovery pipe 13 back to the inside of the reaction device, thereby returning the heated cold air to the inside of the reaction device. The pressure regulating pipe 17 plays the role of balancing the internal pressure of the steam bottle 3 and the water receiving bottle 19. The hot steam inside the preheating bottle 14 is cooled and liquefied, and can flow back to the inside of the water receiving bottle 19 through the condenser pipe 16. The hot air inside the heating box 2 heats the steam bottle 3 and is then discharged through the exhaust pipe 7. Multiple fixing blocks 20, which are set according to the size of the water receiving bottle 19, are in close contact with the water receiving bottle 19 and maintain the shape of the water receiving bottle 19 through close contact, providing support for the water receiving bottle 19. Multiple connecting blocks are located at the top and bottom of the fixing blocks 20. Column 22 connects the heating box 2, water bottle 19, and preheating box 12, and provides support for multiple fixing blocks 20 and connecting rods 21. Multiple side beams 9 and support columns 10 are positioned on the side wall of the preheating box 12 away from the heat return pipe 13, and on the side wall of the heating box 2 away from the hot gas pipe 1, away from the ceramic fiber filter tube production equipment. Multiple side beams 9 and support columns 10 work simultaneously to support the heating box 2, preheating box 12, and their internal components, maintaining the stability of the equipment's center of gravity. The reinforcing outer frame 8 reinforces the heating box 2 and preheating box 12. The probe of the stability measuring instrument located inside the hot gas pipe 1 and exhaust pipe 7 displays the internal temperature of the hot gas pipe 1 and exhaust pipe 7. On the instrument, staff can judge the heat recovery status of multiple steam bottles 3 by observing the temperature difference between two temperature measuring instruments. The probe of the pressure measuring instrument located inside the water receiving bottle 19 can display the gas pressure inside the water receiving bottle 19 on the pressure measuring instrument. Multiple sealing blocks 24 can fill the gap between the heat recovery pipe 13, the air blowing pipe 11 and the preheating box 12 by themselves, to prevent the leakage of cold air entering the preheating box 12 from the air blowing pipe 11 and to prevent the leakage of hot air inside the heating box 2. Multiple gaskets 23 located at the ends of the connecting column 22 can increase the contact area and the fixed area between the connecting column 22 and the heating box 2 by themselves.
