Description

Technical Field

[0001] This utility model relates to the field of skid-mounted dehydration, specifically to a skid-mounted dehydration device. Background Technology

[0002] A skid-mounted dewatering unit is an integrated industrial device used to efficiently process materials or gases containing water to achieve the purpose of separating moisture. Skid-mounted dewatering units are usually based on a modular design, with the equipment and accessories installed on a skid, which facilitates transportation, installation and operation and maintenance.

[0003] In many industrial settings, the presence of moisture can lead to equipment damage, reduced product quality, or system malfunctions. Therefore, to reduce such situations, skid-mounted dehydration devices are chosen to efficiently separate moisture, thereby extending equipment life and improving product purity and quality.

[0004] However, in the existing skid-mounted dehydration devices, nitrogen is not used as a protective or operating gas during the dehydration process, which may result in a large amount of residual moisture, leading to a decrease in purity and making it difficult to meet high standards. At the same time, without nitrogen protection, external impurities may enter through the inlet, affecting the operating environment of the dehydration device.

[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0047] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0048] In practical applications, the raw material waste liquid solvent is introduced into the raw material solvent tank 2 through the pagoda nozzle 9. Nitrogen is introduced through the nitrogen inlet hose 34, and the flow rate of nitrogen is controlled by the nitrogen flow meter 31 and the nitrogen pressure reducing valve 32. The waste liquid and nitrogen are then initially mixed and homogenized inside the raw material solvent tank 2. During the mixing process, the pressure inside the raw material solvent tank 2 is controlled and monitored by the pressure exhaust valve 7 and the vacuum pressure gauge 8.

[0049] Waste liquid enters molecular sieve column 4 and molecular sieve column 5 through automatic control valve 19.

The collection tank 6 is used to temporarily store the dehydrated solvent, and the flow direction of the solvent is controlled by the automatic control valve 21. At the same time, the solvent dehydrated by the molecular sieve enters the qualified solvent tank 3 through the automatic control valve 19 for storage. The pressure exhaust valve 22 and the vacuum pressure gauge 23 are used to control and monitor the pressure inside the tank. Meanwhile, the bottom of the qualified solvent tank 3 is connected to the spiral wound condenser 28 through the manual ball valve 26 and the automatic control valve 27. The spiral wound condenser 28 is used to condense the vapor in the solvent to improve the purity of the solvent. A stainless steel corrugated hose 29 is connected to the vacuum pump 30, which can extract non-condensable gases in the spiral wound condenser 28 to maintain the vacuum and further increase the dehydration effect.

[0051] Therefore, the overall dehydration process is a cycle. After the raw material solvent is dehydrated by molecular sieve, the qualified solvent is collected and stored, while the unqualified solvent or water is discharged or further treated. Through precise control and monitoring, the dehydration effect of the solvent and the stable operation of the system are ensured.

[0052] In summary, by utilizing the above-mentioned technical solution of this utility model, the present utility model, through the setting of raw material solvent tank 2 and qualified solvent tank 3, can not only control the internal pressure of raw material solvent tank 2 under the action of pressure exhaust valve 7 and vacuum pressure gauge 8, preventing damage caused by excessively high or low pressure, but also allows for solvent sampling and analysis and venting operations through the venting sampling port 10, facilitating the monitoring of waste liquid quality. Simultaneously, it can also store qualified solvent after dehydration treatment, ensuring its purity meets the requirements of subsequent processes. Furthermore, the pressure inside the tank is monitored and adjusted through pressure exhaust valve 22 and vacuum pressure gauge 23, ensuring stable solvent storage. The manual ball valve 26 and automatic control valve 27 are connected to the spiral wound condenser 28, which helps to condense and recover vapor in the solvent, improving the solvent recovery rate. This invention, by setting molecular sieve column 4 and molecular sieve column 5, can adsorb moisture in waste liquid, improving the purity of the waste liquid. Simultaneously, the insulated jacket 12 helps maintain the working temperature of molecular sieve column 4 and molecular sieve column 5, improving dehydration efficiency. Furthermore, heat dissipation is achieved through finned heat sink 14 and control valve 15, preventing overheating of molecular sieve column 4 and molecular sieve column 5. This invention, by setting nitrogen flow meter 31 and nitrogen inlet hose 34, constitutes a nitrogen control system, allowing precise control of the nitrogen flow rate entering the raw material solvent tank 2. Simultaneously, the nitrogen pressure reducing valve 32 reduces the nitrogen pressure, ensuring that nitrogen does not cause damage or instability due to excessive pressure when entering the raw material solvent tank 2.
