[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

[0020] like Figure 1-4 As shown, according to the present utility model, a shell and tube condensation dehumidification device is disclosed, comprising a compressed gas inlet 1, the compressed gas inlet 1 is connected to a vortex tube 2, the right end of the vortex tube 2 is connected to a heat exchange chamber 4, a plurality of heat exchange tubes 3 are arranged inside the heat exchange chamber 4, the vortex tube 2 is arranged at the lower half of the heat exchange chamber 4, the upper half of the heat exchange chamber 4 is connected to a cold air outlet 6, an outlet joint 11 is provided at the top of the heat exchange chamber 4, an inlet joint 9 is provided at the top of the heat exchange chamber 4, a confluence chamber 7 is connected below the inlet joint 9, an outlet pipe 14 is provided inside the heat exchange chamber 4, an outlet chamber 15 is provided below the outlet pipe 14, and a drainage joint 17 is connected to the bottom end of the outlet chamber 15;

[0021] In one embodiment of the present invention, the high-speed airflow entering from the compressed gas inlet 1 is separated into hot and cold in the vortex tube 2, and then the cold airflow enters the hot and cold exchange chamber 4 from the right end of the vortex tube 2 and is discharged through the cold air outlet 6. At this time, the multiple internal hot and cold exchange tubes 3 are in a cold airflow environment, and the measured gas enters the intake chamber 7 through the inlet joint 9 and is dispersed into the multiple internal hot and cold exchange tubes 3. In this process, the cold airflow and the measured gas exchange heat through the tube walls of the multiple internal hot and cold exchange tubes 3, reducing the temperature of the measured gas to the corresponding dew point temperature, precipitating water in the measured gas, condensing into droplets in the outlet chamber 15, and entering the dedicated drainage pipe through the drainage joint 17. After drying, the measured gas enters the outlet pipe 14 and enters the gas analyzer through the gas outlet joint 11 for analysis and measurement. The outlet extension pipe 12 at the front end of the gas outlet joint 11 and the outlet pipe 14 are partially covered with a sealing sleeve 13, and the outer tube 5 and the hot and cold exchange chamber 4 are provided with a sealing ring 8.

[0022] like Figure 2 As shown, the temperature sensing rod 20 of the mechanical thermometer extends into the cold and heat exchange tubes 3, and the real-time temperature in the cold and heat exchange tubes 3 is displayed by the pointer of the instrument panel 10 of the mechanical thermometer.

[0023] like Figure 3As shown, by observing the temperature displayed on the instrument panel 10 of the mechanical thermometer, the gas pressure at the compressed gas inlet 1 is adjusted to bring the temperature of the heat exchange chamber 4 to the relative dew point of the gas being measured. The outer tube 5 of the heat exchange chamber 4 is wrapped with thermal insulation 19 to prevent the cold air flow from exchanging heat with the ambient air intake.

[0024] The device of the present application uses a pneumatic device to provide clean monitored gas to a gas analyzer placed in an explosive and hazardous environment, thereby preventing moisture and corrosive gases mixed in the monitored gas from condensing in the pipeline to form corrosive liquids. The compressed air forms a high-speed airflow that passes through the vortex tube to generate cold and hot airflows. The separated cold airflow enters the shell-and-tube hot and cold exchange chamber and performs hot and cold exchange with the measured gas passing through the multi-tube tube, so that the temperature of the measured gas is reduced to the relative dew point temperature, achieving the purpose of dehumidification and water removal. The dried monitored gas enters the gas analyzer. The shell-and-tube condensation and dehumidification device does not require special pipe benders for processing during the production process. The pipes are dispersed in the hot and cold exchange chamber, and multiple pipes circulate, which is not easy to form airflow impact. The measured airflow inside the analyzer is stable. In addition, the shell-and-tube condenser has a good cooling effect, is convenient for automatic control, and is suitable for various industrial application scenarios.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
