Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0022] 1-Vulcanizing machine, 2-Water storage tank, 3-Water pump, 4-Heat exchanger, 5-Overheating heat pump, 6-Gas collection hood, 7-Blower, 8-Blower duct, 9-Filter, 10-Drainage steam trap. Detailed Implementation

[0023] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present utility model. Specific Implementation Example 1:

[0025] Please see Figure 1 As shown, this utility model is a device for recycling condensate from tire vulcanization, including a condensate trap 10, a water storage tank 2, a water pump 3, a heat exchanger 4, an overheating heat pump 5, a gas collection hood 6, a blower 7, and a blower duct 8. The condensate trap 10 is installed at the condensate discharge port of the vulcanizing machine 1.

[0026] The steam trap 10 is connected to the water storage tank 2 via a first pipe. The water storage tank 2 is connected to the heat exchanger 4 via a second pipe. The water pump 3 is installed on the second pipe. The desuperheating water inlet of the heat exchanger 4 is connected to low-temperature desuperheating water, which is room-temperature demineralized water. The desuperheating water outlet of the heat exchanger 4 is connected to the overheating heat pump 5 via a third pipe.

[0027] Since the condensate contains trace amounts of impurities such as rubber particles, oil droplets, release agents, and mold release agents, and has a high iron ion content, the condensate is filtered by a filter to prevent the heat exchanger from clogging and reducing the heat exchange effect after long-term use. A filter 9 is installed on the second pipeline and is placed between the water storage tank 2 and the water pump 3.

[0028] A gas collection hood 6 is installed above the vulcanizing machine 1, and a blower 7 is installed through the upper end of the gas collection hood 6. An air supply duct 8 is installed between the blower 7 and the ventilation window of the overheating heat pump 5.

[0029] The 80-85℃ high-temperature condensate generated during the tire vulcanization process is discharged through a steam trap 10 and collected in a storage tank 2. The condensate in storage tank 2 then enters a filter 9 for filtration to remove impurities. The filtered condensate, driven by a pump 3, enters a heat exchanger 4, where it exchanges heat with ambient-temperature low-temperature desuperheating water. The 80-85℃ condensate cools to 30-40℃, while the 20-25℃ low-temperature desuperheating water heats to 60-70℃. The low-temperature condensate then enters a cooling tower for makeup water, while the high-temperature desuperheating water enters an overheating heat pump 5. The overheating heat pump 5 converts low-temperature energy in the environment into high-temperature energy, heating the high-temperature desuperheating water to generate high-temperature, high-pressure steam. This high-temperature, high-pressure steam is used in production environments such as the vulcanizing machine 1 or the tire drying workshop.

[0030] When the superheated heat pump 5 is running, it needs to absorb low-temperature energy from the air. In winter, the blower 7 on the gas collection hood 6 is turned on. The hot air that escapes from the vulcanizing machine 1 rises and is captured by the gas collection hood 6. Then it is transported to the inside of the superheated heat pump 5 through the air supply pipe 8 to increase the internal temperature of the superheated heat pump 5, ensure the efficiency of the superheated heat pump 5 in heating the high-temperature desuperheating water to generate steam, and maximize the recovery and conversion of the heat waste generated by the vulcanizing machine 1.

[0031] The tire vulcanization condensate recovery and utilization device provided in this embodiment recovers and utilizes the waste heat of the condensate generated during the tire vulcanization process through a heat exchanger 4. Simultaneously, the cooled condensate can also be used as makeup water for the cooling tower, achieving full recovery and utilization of the condensate. The heated desuperheated water is reheated by the superheated heat pump 5, producing high-temperature, high-pressure steam for use in processes such as the vulcanizing machine 1 and tire drying. In winter, a gas collection hood 6, a blower 7, and a blower duct 8 collect the hot air released from the vulcanizing machine 1 and send it to the superheated heat pump 5, maximizing the recovery and utilization of heat waste. Furthermore, the superheated heat pump 5 is a highly efficient energy conversion device that utilizes renewable energy to provide hot water and heating. It can convert low-temperature energy in the environment into high-temperature energy, achieving energy reuse, reducing environmental pollution, and saving energy consumption.

[0032] Among them, heat exchanger 4 adopts a shell-and-tube heat exchanger or a plate heat exchanger.

[0033] To reduce heat loss caused by the pipes, insulation layers are wrapped around the outer walls of the first pipe connection, the second pipe, and the air supply pipe 8.

[0034] The ultra-high temperature and high pressure steam from the superheated heat pump 5 can be used for vulcanizing tires in the vulcanizing machine 1. The ultra-high temperature and high pressure steam from the superheated heat pump 5 is connected to the vulcanizing machine 1 through a third pipe, and the third pipe is wrapped with an insulation layer. The superheated heat pump 5 can also be used in tire drying workshops, as well as in other applications in tire production where steam is required.

[0035] The low-temperature condensate outlet of heat exchanger 4 is connected to the cooling tower. The cooled condensate can be used as makeup water for the cooling tower.
