Description

Technical Field

[0001] The utility model relates to the technical field of chemical equipment, in particular to a chemical high-pressure steam decompression and cooling device. Background Technique

[0002] Chemical condensation equipment is an indispensable part of chemical production, mainly used to condense high-temperature and high-pressure gases or steam into liquids to achieve heat transfer and temperature control. According to different cooling media, condensers can be divided into various types such as water-cooled, air-cooled, and evaporative.

[0003] The working principle of the condenser is based on the principle of heat transfer. By contacting the cooling medium with high-temperature gases or steam, the heat is transferred to the cooling medium to condense it into a liquid.

[0004] The existing condensation equipment condenses steam. When high-pressure steam enters the condensation equipment, the flow rate is too fast, resulting in poor condensation effect. Therefore, it is necessary to decompress the high-pressure steam first. When the existing water-cooling method is used to cool high-pressure steam, flowing water can quickly conduct heat exchange, but the amount of water resources required for flowing water is large. And if you want to quickly cool the heated cooling water, external energy supply is required to cool the heated cooling water, which increases the energy consumption cost of cooling.

[0007] Furthermore, a battery panel is fixedly connected to the inner wall below the cover plate, a protective shell is arranged below the battery panel, a solar power generation panel is fixedly connected to the top of the cover plate, the solar power generation panel is electrically connected to the battery panel, a plurality of electronic refrigeration sheets are fixedly connected to the inner side wall of the cooling chamber, a PLC controller is fixedly connected to the outer wall of the cooling chamber, and the PLC controller is electrically connected to the electronic refrigeration sheets and the battery panel.

[0008] Explanation: Electricity is generated by the solar power generation panel on the cover plate and then stored in the battery panel. The cooling water is cooled by the electronic refrigeration sheet, and the cooling water cools the high-pressure steam to form condensate.

[0009] Furthermore, a temperature sensor is provided at the bottom of the cooling bin, and an electronic valve is provided on the high-pressure steam pipe. The electronic valve and the temperature sensor are electrically connected to the PLC controller.

[0010] Explanation: The temperature of the coolant is monitored by the temperature sensor, and the intake air volume of the high-pressure steam pipe is determined according to the temperature of the coolant. The intake air volume of the high-pressure steam pipe is adjusted by the electronic valve.

[0011] Furthermore, the outer wall of the cooling bin is wrapped with a heat-insulating foam layer, and a bracket is provided at the bottom of the cooling bin.

[0012] Explanation: The heat-insulating foam layer is used to prevent external heat from being transferred to the coolant to raise the temperature of the coolant. The cooling bin is elevated by the bracket, and the gravitational potential energy of the condensate is utilized to make the condensate flow into the liquid collection bin.

[0013] Furthermore, a drain pipe is provided at the bottom of the cooling bin, and a control valve is provided at the end of the drain pipe.

[0014] Explanation: The drain pipe facilitates the replacement of the coolant in the cooling bin.

[0015] The beneficial effects of the present utility model are as follows:

[0016] After the high-pressure steam of the present utility model enters the decompression chamber, the high-pressure steam becomes low-pressure steam. The low-pressure steam is condensed through the condensate pipe to form condensate, and then the condensate is collected. Compared with the existing condensation equipment, the present utility model can effectively decompress and condense the high-pressure steam. The electronic refrigeration sheet is powered by the electric energy generated by solar energy, and the electronic refrigeration sheet cools the coolant. No external power is required during the condensation process. The solar power generation method is green and environmentally friendly, which can reduce the energy consumption cost required for cooling the high-pressure steam.

A PLC controller 25 is fixedly connected to the outer wall of the cooling bin 1. The PLC controller 25 is electrically connected to the electronic refrigeration sheets 24 and the battery panel 21.

[0023] Power is generated through the solar power generation panel on the cover plate and then stored in the battery panel. The cooling water is cooled by the electronic refrigeration sheet, and the cooling water cools the high-pressure steam to form condensate.

[0024] Example 2:

[0025] Based on Example 1, the difference between Example 2 and Example 1 is that a temperature sensor 11 is provided at the bottom of the cooling bin 1, and an electronic valve 41 is provided on the high-pressure steam pipe 4. The electronic valve 41 and the temperature sensor 11 are electrically connected to the PLC controller 25.

[0026] In Example 2, the temperature of the cooling liquid is monitored by the temperature sensor 11, the intake volume of the high-pressure steam pipe 4 is determined according to the temperature of the cooling liquid, and the intake volume of the high-pressure steam pipe 4 is adjusted by the electronic valve 41. Therefore, Example 2 is better than Example 1.

[0027] Example 3:

[0029] In Example 3, the heat-insulating foam layer 12 is used to prevent external heat from being transferred to the cooling liquid to cause the cooling liquid to heat up. The cooling bin is lifted by the support 13, and the gravitational potential energy of the condensate is used to make the condensate flow into the liquid collecting bin 8. Therefore, Example 3 is the best example.

[0033] The working method of the above embodiments includes the following steps:

[0034] S1. High-pressure steam enters the decompression chamber 3 through the high-pressure steam pipe 4. After the high-pressure steam in the decompression chamber 3 enters the decompression chamber 3 with a large space, it forms low-pressure steam. The low-pressure steam flows into the condensation pipe 5, where the condensation pipe 5 exchanges heat with the coolant to form condensate, which then gathers in the liquid collection tank 6 and then flows into the liquid collection bin 8 through the collection pipe 7 for collection;

[0035] S2. The electric energy generated by the solar power panel 23 is stored in the battery panel 21. The battery panel 21 supplies power to the solenoid valve 41, the temperature sensor 11, and the electronic cooling sheet 24. The electronic cooling sheet 24 cools the coolant. According to the temperature of the coolant monitored by the temperature sensor 11, the flow rate of the high-pressure steam is determined, and through
