Abstract
Description
Technical Field
[0001] This utility model belongs to the field of waste treatment technology, specifically referring to a condensation system for waste treatment. Background Technology
[0002] In the processing of household waste, kitchen waste, and other similar materials, it is often necessary to heat and stir the waste to achieve purposes such as composting and dehydration. During the negative pressure heating process in the drying and stirring chamber, a large amount of steam is generated, which causes the negative pressure inside the chamber to rise.
[0003] When the pressure inside the silo rises to a preset threshold, the vacuum pump will start to evacuate air to maintain negative pressure. While removing steam, the vacuum pump inevitably carries away a significant amount of heat. This heat, as it passes through pipes and other components, can overheat them, damaging them over time and affecting the equipment's lifespan and normal operation. Furthermore, direct steam discharge wastes energy and impacts the environment. If the heat cannot be effectively removed in a timely manner, the pressure inside the silo will rise rapidly due to the continuous steam generation, requiring the vacuum pump to start more frequently, increasing energy consumption and equipment wear. Therefore, a condensation system for waste treatment is needed to solve these problems. Utility Model Content
[0004] To address the aforementioned problems, this invention provides a waste treatment condensation system with a reasonable structure, high condensation efficiency, effective protection of equipment such as vacuum pumps, heat recovery, and stable negative pressure operation.
[0005] The technical solution adopted by this utility model is as follows: The condensation system for waste treatment of this utility model includes a condensation tank and a pressure tank. The condensation tank is connected to the drying and stirring chamber. The pressure tank is located on one side of the condensation tank. The inlet of the pressure tank is connected to the outlet of the condensation tank. A vacuum pump is provided on one side of the pressure tank. A vacuum exhaust pipe is provided between the vacuum pump and the pressure tank. The vacuum exhaust pipe connects the outlet of the pressure tank and the vacuum pump. The condensation tank adopts a water-cooled condenser.
[0006] Furthermore, a steam filter is provided between the condenser and the drying mixing chamber. The steam filter is connected to the steam outlet of the hot mixing chamber, and the outlet of the steam filter is connected to the steam inlet of the condenser. The filtered steam enters the condenser. The steam filter is used to filter the steam generated by the drying mixing chamber, remove impurities carried in the steam, and prevent impurities from entering subsequent components and causing blockage or damage.
[0007] Furthermore, the condenser is provided with an inlet pipe and an overflow pipe on both sides. One end of the inlet pipe is connected to the water inlet of the condenser body and the other end is connected to an external water source. The inlet pipe is used to introduce cold water into the condenser body to achieve forced cooling of the steam. One end of the overflow pipe is connected to the overflow port of the condenser body and the other end is connected to the drain pipe. When the water level in the condenser body reaches the height of the overflow port, the excess water is discharged into the drain pipe through the overflow pipe to ensure the stability of the water level inside the condenser body.
[0008] Furthermore, the bottom of the condenser tank is provided with a condensate drain outlet, which is connected to the drain pipe. After being cooled in the condenser tank, the steam becomes condensate and is discharged into the drain pipe through the condensate drain outlet.
[0009] The beneficial effects of this utility model by adopting the above structure are as follows:
[0010] 1. By installing a steam filter, steam can be filtered to remove impurities, protect downstream components, and reduce the probability of malfunctions;
[0011] 2. It significantly reduces the temperature of the gas entering the vacuum pump, effectively preventing high temperatures from damaging the vacuum pump, its front-end pipes, and other components, extending the service life of the equipment, and reducing maintenance costs;
[0012] 3. It quickly and effectively removes the steam load generated by the mixing chamber, which helps maintain the stability of the system negative pressure, reduces the start-stop frequency of the vacuum pump, and reduces energy consumption and equipment wear;
[0013] 4. The steam generated by the process is effectively treated, and the condensate is discharged in an orderly manner. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0018] like Figure 1 and Figure 2 As shown, the proposed waste treatment condensation system includes a condensation tank 1 and a pressure tank 2. The condensation tank 1 is connected to the drying and mixing chamber. The pressure tank 2 is located on one side of the condensation tank 1. The inlet of the pressure tank 2 is connected to the outlet of the condensation tank 1. A vacuum pump 3 is provided on one side of the pressure tank 2. A vacuum exhaust pipe 4 is provided between the vacuum pump 3 and the pressure tank 2. The vacuum exhaust pipe 4 connects the outlet of the pressure tank 2 and the vacuum pump 3. The condensation tank 1 adopts a water-cooled condenser. A steam filter 5 is provided between the condensation tank 1 and the drying and mixing chamber. The steam filter 5 is connected to the steam outlet of the drying and mixing chamber. The outlet of the steam filter 5 is connected to the steam inlet of the condensation tank 1.
[0019] The condenser tank 1 is provided with an inlet pipe 6 and an overflow pipe 7 on both sides. One end of the inlet pipe 6 is connected to the water inlet of the condenser tank 1 and the other end is connected to an external water source. One end of the overflow pipe 7 is connected to the overflow outlet of the condenser tank 1 and the other end is connected to a drain pipe. The bottom of the condenser tank 1 is provided with a condensate drain outlet 8, which is connected to a drain pipe.
[0020] In practical use, the drying and mixing chamber generates high-temperature steam during heating, causing the negative pressure inside the chamber to rise. When the pressure inside the chamber reaches the preset upper limit, the vacuum pump 3 starts. The high-temperature steam first enters the steam filter 5 to remove solid particles, oil, and other impurities. The filtered high-temperature steam then enters the condenser tank 1. Simultaneously, tap water is continuously injected into the condenser tank 1 through the water inlet pipe 6. The steam comes into full contact with the cold water in the condenser tank 1, undergoing heat exchange, and the steam is cooled and condensed into condensate. The condensate collects at the bottom of the condenser tank 1 and is discharged into the drain pipe through the condensate outlet 8. When the water level in the condenser tank 1 reaches the overflow height, the excess water is discharged into the drain pipe through the overflow pipe 7. The uncondensed low-temperature, low-humidity gas rises to the top of the tank. The vacuum pump 3 extracts the gas from the condenser tank 1 through the vacuum exhaust pipe 4, maintaining the negative pressure environment of the condenser tank 1, allowing the steam to smoothly enter and be processed.
[0021] Through this condensation process, most of the heat carried by the steam is absorbed and carried away by the cooling water. The heat is forcibly cooled and recovered into the cooling water, and finally discharged with the overflow water and condensate. The temperature of the gas entering the vacuum pump 3 is significantly reduced, effectively protecting the vacuum pump 3 and upstream pipes, valves, and other components from high-temperature damage. At the same time, efficient condensation reduces the steam load, enabling the vacuum pump 3 to maintain the system negative pressure more effectively and reducing the frequent start-stop of the vacuum pump 3 caused by rapid pressure recovery.
