Description

Technical Field

[0001] The utility model relates to the field of condensers, in particular to a one-way condenser with a storage tank. Background Art

[0002] The condenser is a component of the refrigeration system and a type of heat exchanger. It can convert gas or vapor into liquid and transfer the heat in the pipe to the air near the pipe in a very fast manner.

[0003] The condensers (heat exchangers) in the prior art not only use air condensation, but some condensers also use water cooling in consideration of condensation efficiency. In addition, the water cooling method can also recover and utilize the waste heat generated by condensation during the gas condensation process, thereby effectively improving energy utilization.

[0004] Among them, the Chinese patent with patent number ZL 202323498473.2 discloses: "A freeze dryer water condenser includes a rotating shaft, one end of the rotating shaft is rotatably installed with an active bevel gear, one end of the threaded rod is rotatably connected with a driven bevel gear, and the active bevel gear and the driven bevel gear are meshed with each other, and a scraper is threadedly connected on the arc surface of the threaded rod, and a cleaning brush is fixedly connected to the arc edge of the scraper. The rotating shaft and the active bevel gear are driven by a driving motor to rotate, thereby driving the driven bevel gear and the threaded rod to rotate. The rotation of the threaded rod causes the scraper to move along the arc surface of the threaded rod, and the cleaning brush also moves accordingly. The scraper and the cleaning brush cooperate with each other to clean the inner wall of the condenser body and the arc surface of the condenser tube to remove dirt and scaling. This solution can clean the inside of the water condenser, prevent the blockage and increase of resistance of the pipeline, ensure the normal operation of the water condenser, and improve the efficiency of condensation."

[0005] However, including the solutions described in the above patents, there is a problem with the condensers in the prior art, that is, during the use of the condenser, when the gas is converted into liquid in the heat exchange device of the condenser, the liquid needs to be transported to a storage tank through a pipeline for storage, so that the liquid produced by the condensation can be reused later, or the liquid can be neutralized and then discharged. However, in the existing implementation, the heat exchange device and the liquid storage tank are placed separately and then connected with a pipeline, which will seriously occupy the production space and easily cause liquid to remain in the connecting pipeline. Summary of the invention

[0006] In order to overcome the shortcomings of the prior art that a heat exchange device and a liquid storage tank for storing liquid are connected by a pipeline, which occupies production space and easily causes residual liquid in the pipeline, the utility model provides a one-way condenser with a storage tank.

[0010] A heat exchange device, wherein an isolated ventilation cavity and a liquid cavity are arranged inside the heat exchange device; the heat exchange device comprises a connecting portion, and the connecting portion is also provided with an air outlet communicating with the ventilation cavity, and the connecting portion can be connected to a connecting pipe on a storage tank, so that the heat exchange device is connected above the storage tank, and the ventilation cavity is communicated with the liquid storage cavity;

[0011] The surface of the heat exchange device is also provided with an air inlet pipe connected to the ventilation cavity, and a liquid inlet pipe and a liquid outlet pipe connected to the liquid cavity;

[0012] The manhole assembly comprises a manhole pipe which is arranged on the surface of the storage tank and communicates with the liquid storage cavity, and a manhole cover which is arranged on the manhole pipe.

[0014] Furthermore, the heat exchange device also includes an air intake cover connected to the upper end of the shell, the inner wall of the air intake cover and the upper tube plate are combined to form an air intake cavity, the air intake cavity is connected to the ventilation cavity, and the air intake pipe is arranged on the air intake cover.

[0015] Furthermore, the tube sheet includes an upper tube sheet and a lower tube sheet, wherein the circumferential side of the upper tube sheet is connected to the air intake cover by bolts, and the circumferential side of the lower tube sheet is connected to the connecting pipe by bolts.

[0016] Furthermore, a plurality of support plates are connected to the inner wall of the shell, and the support plates are sleeved on the outer side of the heat exchange tube to support the heat exchange tube.

[0017] Furthermore, the manhole assembly also includes a plurality of locking rods and locking knobs threadedly connected to the locking rods, and the locking rods are connected to the side walls of the manhole pipes; the locking knobs can be tightened or loosened relative to the locking rods to achieve contact with or separation from the manhole cover; the locking rods are rotatably arranged relative to the manhole pipes, and the locking rods can be rotated to move away from or closer to the manhole cover.

[0018] Furthermore, an observation window is provided on the manhole cover, the observation window is connected to the liquid storage cavity, and a transparent or translucent observation partition is provided in the observation window.

[0019] Furthermore, a liquid level monitoring device is also included; the liquid level monitoring device includes a liquid level gauge connected to the storage tank, the storage tank is provided with a connecting hole, and the lower end of the liquid level gauge passes through the connecting hole and extends into the liquid storage cavity.

[0020] Furthermore, a feed pipe communicating with the liquid storage cavity is also provided on the surface of the storage tank.

[0021] The condensation process, body discharge process and maintenance process of the utility model:

[0022] Condensation process: The gas to be condensed is first input into the heat exchange device through the air inlet pipe, and first enters the air inlet cavity, and then is transferred from the air inlet cavity to the ventilation cavity. At the same time, water is also input into the liquid ventilation cavity from the liquid inlet pipe. At this time, the heat on the gas to be condensed can be transferred to the water through the tube wall of the heat exchange tube, and the gas is condensed and turned into liquid. The liquid eventually falls into the storage tank through the connecting pipe along the heat exchange tube, and the water that has been heated by the heat is output from the heat exchange device through the liquid outlet pipe. The condensed liquid will be stored in the liquid storage cavity of the storage tank, and some of the uncondensed gas can be discharged through the exhaust pipe after entering the liquid storage cavity, and refluxed and condensed again;

[0023] Discharge process: When the liquid level in the storage tank reaches the threshold value, the liquid can be discharged at once through the discharge pipe. However, considering that some liquids are corrosive, a neutralizer needs to be input into the storage tank through the feed pipe before discharge to neutralize the liquid before discharge.

[0024] Maintenance process: When the storage tank needs to be cleaned and maintained, the locking knobs can be loosened to release the tightness between the locking knobs and the manhole cover, and the locking rod can be rotated relative to the manhole pipe so that the locking rod and the locking knob are away from the manhole cover. At this time, the manhole cover can be opened and the staff can clean and maintain the storage tank through the manhole pipe.

While realizing the function of the condenser, the heat exchange device is directly connected to the top of the storage tank, which can effectively save production space. In addition, since the liquid will directly fall into the storage tank after condensation, it can effectively avoid liquid residue;

[0027] 2. The heat exchanger uses water cooling to condense the gas. While achieving the condensation function, it can also utilize the waste heat generated by the gas condensation;

[0028] 3. An observation window is provided on the manhole cover, through which the height of the liquid level in the storage tank can be monitored in real time;

[0029] 4. A liquid level meter is also provided, which can issue a prompt reminder when the liquid level in the storage tank reaches a certain height. Therefore, the staff does not need to frequently observe the liquid level in the storage tank, which can effectively save labor. BRIEF DESCRIPTION OF THE DRAWINGS
