Description

Technical Field

[0001] The utility model relates to a condensate temporary storage device and belongs to the technical field of condensate storage tanks. Background Art

[0002] Condensate is widely used in industrial production processes and plays a variety of important roles in the industrial and scientific fields, including energy recovery, humidity control, dehumidification, separation and purification, and safety protection. In some production processes, the condensate is generated very quickly, and the container capacity is limited or the container is difficult to move; or the condensate may contain harmful substances or require special treatment, but it is currently impossible to treat or discharge; or sometimes the condensate needs to be monitored or analyzed to determine its composition or other characteristics. In this case, a liquid storage tank is often required to temporarily store the condensate.

[0003] However, the commonly used liquid storage tanks lack safety measures, and the pressure and temperature inside the liquid storage tanks cannot be regulated, which poses a safety hazard and is not easy for subsequent production or testing. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solution: a condensate temporary storage device, comprising:

[0006] A tank body, comprising a condensate inlet for receiving condensate and a condensate outlet for conveying condensate;

[0007] A pressure relief mechanism is arranged on the top of the tank body;

[0008] The heat exchange mechanism comprises a heat exchanger arranged inside the tank body, an auxiliary device arranged outside the tank body to assist the heat exchanger in working, and a fluid pipeline connecting the heat exchanger and the auxiliary device.

[0009] Furthermore, the pressure relief mechanism includes a first pressure relief unit for balancing the gas pressure in the tank body and a second pressure relief unit for preventing the tank body from exploding.

[0010] Furthermore, the first pressure relief unit is any one of a breathing valve, a safety valve, an exhaust valve or a pressure release valve.

[0011] Furthermore, the second pressure relief unit is any one of an explosion relief piece, an explosion relief door or a rupture disk.

[0012] Furthermore, the heat exchanger is a partition type heat exchanger.

[0014] Furthermore, a liquid level detector is also arranged on the inner wall of the tank body.

[0015] Furthermore, a temperature detector is also arranged on the inner wall of the tank.

[0016] The beneficial effects of the utility model are as follows: the application provides a pressure relief mechanism on the tank body, and uses the pressure relief mechanism to adjust the air pressure in the tank body to reduce or prevent the occurrence of explosion, thereby reducing the safety hazards of the liquid storage tank. At the same time, a heat exchanger is used to control the temperature of the condensate, thereby avoiding the condensate temperature being too high, which causes the pressure in the tank body to rise too quickly, and at the same time causes the saturated steam of the condensate in the tank body to explode, thereby causing the explosion hazard. The temperature control of the condensate also facilitates the subsequent use or detection of the condensate.

[0024] Please refer to Figure 1 A condensate temporary storage device is shown in one embodiment of the present application, and the condensate temporary storage device includes a tank body 1, a pressure relief mechanism and a heat exchange mechanism.

[0025] The tank body 1 includes a condensate inlet 11 for receiving condensate and a condensate outlet 12 for conveying condensate. The tank body 1 is cylindrical as a whole, and has arc domes at both ends. The condensate inlet 11 is arranged in the upper middle part of the tank body 1, close to the arc dome at the top, and the condensate outlet 12 is arranged at the arc dome at the bottom, and is located at the lowest point. The condensate inlet 11 and the condensate outlet 12 are both provided with solenoid valves 13, which are connected to equipment for conveying or receiving condensate to realize switch control of the condensate inlet 11 and the condensate outlet 12, so as to facilitate the transfer of condensate.

[0026] The pressure relief mechanism is arranged at the top of the tank body 1. Since the gas or liquid is above the tank body 1, the pressure relief mechanism is arranged at the top to directly release the pressure and avoid the pressure spreading inside the tank body 1. It can be easier to control the leakage of the liquid and reduce the impact on the environment and personnel.

[0027] The pressure relief mechanism includes a first pressure relief unit 21 for balancing the air pressure in the tank body 1 and a second pressure relief unit 22 for preventing the tank body 1 from exploding. The second pressure relief unit 22 is arranged at the top of the arc dome of the tank body 1, and the first pressure relief unit 21 is arranged at the arc dome and away from the top of the arc dome. The function of the first pressure relief unit 21 is that when the pressure in the tank body 1 rises to a specific value, the first pressure relief unit 21 is connected to the outside to release the pressure to avoid continuous pressure accumulation in the tank body 1. The function of the second pressure relief unit 22 is that when the pressure release of the first pressure relief unit 21 is slower than the increase of the air pressure in the tank body 1, resulting in the pressure accumulation in the tank body 1 to a preset value, the second pressure relief unit 22 is opened to quickly release the pressure to avoid the explosion of the tank body 1, wherein the preset value is greater than the specific value and less than the explosion value of the tank body 1.

[0028] The first pressure relief unit 21 is any one of a breathing valve, a safety valve, an exhaust valve or a pressure release valve. Preferably, the first pressure relief unit 21 is a breathing valve. When the internal pressure of the tank body 1 is greater than the external environment or a set value, the breathing valve opens the air outlet channel to allow the gas in the tank body 1 to flow out, thereby releasing the pressure to balance the pressure difference inside and outside the tank body 1. The functions of the safety valve, exhaust valve and pressure release valve are similar to those of the breathing valve and are not described in detail here.

[0029] The second pressure relief unit 22 is any one of an explosion relief piece, an explosion relief door or a rupture disk. Preferably, the second pressure relief unit 22 is an explosion relief piece. When the pressure in the tank body 1 exceeds the preset value that the explosion relief piece can withstand, the explosion relief piece ruptures to release the pressure inside the container, thereby preventing the container from exploding or being damaged due to excessive pressure. After the pressure is released and restored to a safe range, the integrity and function of the container can be restored by replacing or repairing the explosion relief piece. Among them, the explosion relief door and the rupture disk have similar functions to the explosion relief piece. They only need to rupture or open to quickly release the excessive pressure inside the container to protect the safety of the container and the surrounding environment, and will not be elaborated here.

[0030] The heat exchange mechanism includes a heat exchanger 31 arranged inside the tank body 1, an auxiliary device (not shown) arranged outside the tank body 1 to assist the heat exchanger 31 in working, and a fluid pipeline 32 connecting the heat exchanger 31 and the auxiliary device. Among them, the heat exchanger 31 is a partition wall heat exchanger, which is arranged at the bottom of the tank body 1. The partition wall heat exchanger includes a shell (not shown), a tube bundle arranged inside the shell, and a tube sheet (not shown) connecting the tube bundle and the shell. The tube bundle is composed of a plurality of pipes, which are arranged in parallel and connected to the tube sheet at both ends. The pipes are connected to each other through the tube sheet to form a tube side flow channel, which is connected to the fluid pipeline 32 so that the auxiliary device drives the heat exchange medium to flow in the pipe. A shell side flow channel is formed between the shell and the tube bundle, one end of the shell side flow channel is connected to the condensate inlet 11, and the other end is connected to the inside of the tank body 1. The condensate exchanges heat with the heat exchange medium in the tube side flow channel through the shell side flow channel, thereby realizing the temperature control of the condensate.

[0031] Of course, in order to store the condensate more quickly, in other embodiments, the partition-type heat exchanger may also be provided with a shell, and the condensate inlet 11 is connected to the tank body 1, and the condensate is stored in the tank body 1 and directly contacts the surface of the tube bundle, and then exchanges heat with the heat exchange medium.

[0032] The auxiliary equipment includes an energy unit for providing a heat exchange medium and a fluid pump for driving the heat exchange medium to flow between the energy unit and the partition heat exchanger. The types of heat exchange medium include gas, liquid and steam. If the condensate needs to be heated, a high-temperature medium is selected. If the condensate needs to be cooled, a low-temperature medium is selected. The medium can be selected according to the needs and is not limited here.

[0033] A liquid level detector is also provided on the inner wall of the tank body 1, through which the condensate in the tank body 1 is monitored in real time to avoid the condensate in the tank body 1 exceeding the reserve and causing unnecessary safety accidents.

[0034] A temperature detector is also provided on the inner wall of the tank body 1, through which the temperature of the condensate in the tank body 1 is monitored in real time, so that the temperature control adjustment is carried out in cooperation with the heat exchange mechanism, so as to more accurately control the temperature of the condensate.

[0035] In addition, a display unit is also provided on the tank body 1, and the display unit is connected to the liquid level detector and the temperature detector signal to display the liquid level and temperature detected by the liquid level detector and the temperature detector, so that the staff can view them in real time. At the same time, a pressure detector can also be provided on the inner wall of the tank body 1, and the pressure detector is connected to the display unit signal. The display unit is connected to an audible and visual alarm unit. When the pressure in the tank body 1 approaches a preset value, the audible and visual alarm unit is triggered to alarm, so as to remind the staff to avoid being frightened by the sudden rupture of the venting disc, and at the same time, the venting disc can be replaced in advance.

[0036] The present application provides a pressure relief mechanism on the tank body and uses the pressure relief mechanism to adjust the gas pressure in the tank body to reduce or prevent the occurrence of explosion, thereby reducing the safety hazards of the liquid storage tank. At the same time, a heat exchanger is used to control the temperature of the condensate to avoid the condensate temperature being too high, which causes the pressure in the tank body to increase too quickly and causes the saturated steam of the condensate in the tank body to explode, thereby causing the risk of explosion. The temperature control of the condensate also facilitates the subsequent use or detection of the condensate.

[0037] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
