Description

Technical Field

[0001] The utility model belongs to the technical field of gas processing, and in particular relates to a continuous gas condensation processing device. Background Art

[0002] In the field of pharmaceutical chemicals, gas condensation is a very important process step, especially in drug production, intermediate synthesis, solvent recovery and other processes.

[0003] However, conventional gas condensation processing devices (especially for gases condensed under very high pressure, such as low-boiling gases) are usually intermittent in the collection and processing of condensed liquid. Specifically, when the condensed liquid in the tank accumulates to a certain amount, it is necessary to close the air inlet valve to cut off the air intake source, and then open the drain valve to discharge the condensed liquid; then re-control the pressure in the tank and open the air inlet valve to resume the condensation process of the gas. The operation is very cumbersome and easily affects the working efficiency of the condensation. Utility Model Content

[0004] The purpose of the utility model is to provide a continuous gas condensation processing device in response to the above-mentioned technical problems, which can achieve the effect of being able to continuously condense gas without closing the air inlet valve, thereby effectively improving convenience and work efficiency.

[0005] In view of this, the utility model provides a continuous gas condensation processing device, comprising:

[0006] The tank body has an upper chamber and a lower chamber formed therein;

[0007] A condensing assembly is installed in the upper chamber of the tank;

[0008] The upper chamber is provided with a first air inlet, a first air outlet and a liquid outlet, the lower chamber is provided with a liquid inlet and a liquid discharge port, and the liquid outlet is connected to the liquid inlet through a first connecting pipe, and a first valve for opening and closing is provided.

[0015] In the above technical solution, further, the condensation component includes:

[0016] A jacket is sleeved on the surface of the tank body, is located above the first air inlet, and is arranged corresponding to the upper chamber;

[0017] The jacket is provided with a refrigerant inlet and a refrigerant outlet, and the refrigerant inlet is arranged lower than the refrigerant outlet.

[0018] In the above technical solution, further, the condensation component also includes:

[0019] The heat exchange tube is installed in the upper chamber, and both ends of the tube pass through the tank body and are connected with the jacket;

[0020] Wherein, there are multiple heat exchange tubes.

[0021] In the above technical solution, further, the condensation component also includes:

[0022] The baffle is installed in the jacket and is used to block the refrigerant inlet from being connected to the refrigerant outlet through the jacket.

[0023] Wherein, both ends of the heat exchange tube are respectively arranged close to the refrigerant inlet and the refrigerant outlet.

[0029] 1. By setting a double-layer structure of an upper chamber and a lower chamber in the tank body, uninterrupted condensation and drainage can be achieved. The condensed liquid in the upper chamber flows through the liquid outlet through the first connecting pipe and enters the lower chamber through the liquid inlet. When the liquid in the lower chamber is full, the first valve can be closed and then discharged. There is no need to close the first air inlet, which effectively improves the continuity of condensation and improves work efficiency.

[0042] The upper chamber 2 is provided with a first air inlet 5, a first air outlet 6 and a liquid outlet 7, the lower chamber 3 is provided with a liquid inlet 8 and a liquid outlet 9, and the liquid outlet 7 is connected to the liquid inlet 8 through a first connecting pipe 10, and a first valve 11 for opening and closing is provided;

[0043] Meanwhile, the first valve 11 may be a manual ball valve or an automatic solenoid valve;

[0044] In addition, the tank body 1 is also provided with a vacuum gauge for detecting the vacuum degree in the tank body 1 and a liquid level gauge for detecting the liquid level in the upper chamber 2 and the lower chamber 3. The vacuum gauge and the liquid level gauge are both existing technologies, and their specific structures are not repeated here. The tank body 1 is also provided with a vent pipe and a vent valve for venting on the inner wall of the upper chamber 2.

[0045] It can be seen from the present embodiment that by arranging a double-layer structure of an upper chamber 2 and a lower chamber 3 in the tank body 1, uninterrupted condensation and drainage can be achieved. The condensed liquid in the upper chamber 2 flows through the liquid outlet 7, passes through the first connecting pipe 10, and enters the lower chamber 3 via the liquid inlet 8. When the liquid in the lower chamber 3 is full, the first valve 11 can be closed for discharge, and there is no need to close the first air inlet 5, thereby effectively improving the continuity of condensation and improving work efficiency.

[0051] Embodiment 3:

[0052] This embodiment provides a continuous gas condensation processing device, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

Specifically, when the three-way valve is connected to the second air outlet 13 and the second air inlet 14, the air pressure in the upper chamber 2 and the lower chamber 3 is the same, and the first valve 11 is in the open state, and the liquid condensed in the upper chamber 2 flows into the lower chamber 3. When the condensed liquid in the lower chamber 3 is almost full and needs to be discharged, the first valve 11 is closed, and the three-way valve is connected to the second air inlet 14 and the vent 16 to form normal pressure in the lower chamber 3, so as to facilitate the discharge of the condensed liquid in the lower chamber 3 and improve efficiency.
