Description

Technical Field

[0001] This utility model relates to the technical field of gas drying equipment, specifically a compressed gas drying system with zero-air-consumption blower cold blowing regeneration. Background Technology

[0002] Gas dehydration methods generally include cryogenic methods, solid-state adsorption methods, chemical reaction methods, and membrane separation methods, among which solid-state adsorption is a commonly used method. Solid-state adsorption separation involves using a porous solid adsorbent to concentrate one or more components of a gas onto the solid surface, thus separating them from other components. A common gas adsorption separation technique is temperature-switching adsorption (TSA). TSA utilizes the characteristic that the adsorption capacity of an adsorbent changes with the adsorption temperature. Under conditions where the adsorbent selectively adsorbs different gas components, these adsorbed components are desorbed at high temperatures for the next adsorption cycle. Multiple adsorbers can be used to achieve continuous gas separation. However, existing TSA processes suffer from excessively high water content, high energy consumption, and low product gas quality, increasing processing costs. To address these problems, we propose a zero-consumption compressed gas drying system with cold blowing regeneration. Utility Model Content

[0003] The purpose of this invention is to provide a compressed gas drying system that consumes no finished gas, produces no exhaust pollution or noise, and reduces costs by using a zero-gas-consumption blower-cooled regeneration system.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a compressed gas drying system with zero-consumption air blowing and regeneration, comprising an inlet pipe, one end of which is connected to a cooler, and the other end of which is connected to a heater. The other end of the cooler is connected to a first connecting pipe, the other end of which is connected to a separator, the other end of which is connected to a second connecting pipe, the other end of which is connected to a third connecting pipe, and the other end of which is connected to a fourth connecting pipe. The surface of the fourth connecting pipe is connected to a fifth, a sixth, and a seventh connecting pipe, and an eighth connecting pipe is provided on one side of the fourth connecting pipe. The third, sixth, and seventh connecting pipes are all connected to the eighth connecting pipe. The surface of the seventh connecting pipe is connected to a ninth and a tenth connecting pipe. The other end of the ninth connecting pipe is connected to a silencer, and the other end of the tenth connecting pipe is connected to a regeneration cooler. The other end is connected to an eleventh connecting pipe, the other end of which is connected to a blower, the other end of which is connected to a twelfth connecting pipe, the other end of which is connected to a first adsorption tower, the other end of which is connected to a thirteenth connecting pipe, the other end of which is connected to a fourteenth connecting pipe, the surface of which is connected to a fifteenth, sixteenth, seventeenth, and eighteenth connecting pipes respectively, a nineteenth connecting pipe is provided on one side of the fourteenth connecting pipe, the fifteenth, sixteenth, seventeenth, and eighteenth connecting pipes are all connected to the nineteenth connecting pipe, the twelfth connecting pipe is connected to the seventeenth connecting pipe, the other end of which is connected to a twentieth connecting pipe, the other end of which is connected to a second adsorption tower, the other end of which is connected to a twenty-first connecting pipe, and the other end of which is connected to an eighth connecting pipe.

[0005] The above technical solution involves connecting a first adsorption tower, a second adsorption tower, a cooler, a separator, a heater, a blower, a regeneration cooler, and a silencer into a network to achieve adsorption, regeneration, and pressure equalization. This reduces the moisture content of the gas entering the system, improving the quality of the product gas while reducing energy consumption and production costs. It produces low-dew-point dry gas. The cold-blowing airflow is powered by a blower, and the circulating cold-blowing airflow is output from the blower and enters the second adsorption tower from bottom to top to cool the adsorbent. After exiting the second adsorption tower, the cold-blowing airflow is drawn into the blower, pressurized, and then output, before being cooled again by the regeneration cooler, forming a complete cold-blowing cycle until the temperature of the second adsorption tower drops to the set temperature, allowing it to circulate back within the system for reuse. This process consumes no finished product gas, reducing costs. There is no venting throughout the process, eliminating noise and pollution caused by sudden compressed gas emissions. The switching is smooth, extending the adsorbent's lifespan. This equipment achieves zero emissions and saves energy.

[0006] The present invention is further configured such that both the first adsorption tower and the second adsorption tower are provided with an adsorption desiccant.

[0007] The above technical solution involves setting up an adsorption desiccant and using pipelines and the desiccant to reduce the overall moisture content of the gas entering the system, thereby meeting quality requirements.

[0008] The present invention is further configured such that the cooler is either water-cooled or air-cooled.

[0009] The above technical solution is adopted by setting the cooler to be either water-cooled or air-cooled, which facilitates its use.

[0010] The present invention is further configured such that the heater is one of an electric heater and a heat exchanger.

[0011] The above technical solution is adopted by setting the heater to be either an electric heater or a heat exchanger, which facilitates its use.

[0012] The present invention is further configured such that an online analyzer is provided at the output end of the first adsorption tower and the second adsorption tower.

[0013] The above technical solution involves installing an online analyzer to analyze whether the gas meets the required standards.

[0014] Compared with the prior art, the present invention provides a compressed gas drying system, which has the following beneficial effects:

[0015] 1.

[0016] 2. This utility model produces low dew point dry gas by using a cold blowing airflow powered by a blower. The cold blowing circulating airflow is output from the blower and enters the second adsorption tower from bottom to top to cool the adsorbent. After the cold blowing airflow exits the second adsorption tower, it is drawn into the blower, pressurized, and then output. It is then cooled by the regeneration cooler, forming the entire cold blowing cycle until the temperature of the second adsorption tower drops to the set temperature. This process does not consume any finished gas and reduces costs.
