It includes a main tank body component, a pressure relief tank body component, an external pipe component, a pressure relief assembly and a reflux assembly. The inner tank and the outer tank are arranged in an inner and outer double body. The external pipe component is connected to the cavity between the inner wall of the outer tank and the outer wall of the inner tank, and the temperature can be reduced.

Description

Technical Field

[0001] The present invention relates to the technical field of chemical equipment, and in particular to a gas safety release device for chemical equipment. Background Art

[0002] The chemical industry is one of the more important industries at present and plays an important role in social development. However, in the process of industry development, due to poor management and other reasons, chemical substances are prone to leakage, affecting the surrounding environment and people's life safety. Therefore, in the process of chemical gas storage, specifically, a safety release device should be equipped in the chemical tank.

[0003] Existing chemical tank discharge devices are either too simple, with only a single mechanical discharge valve. When the temperature rises and the gas pressure in the chemical tank is too high, the dangerous excess gas will be urgently discharged into the external environment through the mechanical discharge valve, which will not only cause environmental pollution but also lead to waste of resources; or they are too complicated and require the help of temperature control system and cooling system. Although the effect is good, it also has the disadvantages of inconvenient operation and high cost. Summary of the invention

[0004] The purpose of the present invention is to provide a safe gas release device for chemical equipment, which can not only utilize the combined effect of the pressure relief component and the external pipe component to simultaneously form a flow cooling effect on the cooling liquid to a certain extent while releasing the gas into the pressure relief tank; but also utilize the reflux component to enable the gas temporarily stored in the pressure relief tank to be returned to the inner tank when the pressure of the chemical gas in the inner tank drops to a certain value, so as to avoid environmental pollution and waste of resources.

[0005] The object of the present invention is achieved through such a technical solution, a gas safety release device for chemical equipment, comprising a main tank body component, a pressure relief tank body component, an external pipe component, a pressure relief assembly and a reflux assembly, the main tank body component comprising an outer tank and an inner tank, the pressure relief tank body component comprising a pressure relief tank, the external pipe component comprising an external water pipe, the pressure relief assembly comprising a pneumatic box and a gas relief valve box, and the reflux assembly comprising a reflux valve box and an outer sliding sleeve;

[0006] The inner tank is located in the middle of the outer tank, the outer wall of the inner tank and the inner wall of the outer tank are filled with coolant, the pressure relief tank is located on one side of the outer wall of the outer tank, the two ends of the external water pipe are respectively connected to the cavity between the outer wall of the inner tank and the inner wall of the outer tank, the main line of the external water pipe is connected to a water wheel box, and a water wheel fan is screwed inside the water wheel box;

[0007] The pneumatic box is located on one side of the water wheel box, and the inner cavity of the inner tank is connected to the air inlet end of the pneumatic box, a pneumatic wheel is screwed inside the pneumatic box, the air relief valve box is connected to the air outlet end of the pneumatic box, the air inlet end of the pressure relief tank is unidirectionally connected to the air outlet end of the air relief valve box, and the inside of the air relief valve box is elastically sealed and slidably connected to one side of the pneumatic box with an air relief valve core, and the air relief valve core can open and close the air outlet end of the air relief valve box;

[0008] The outlet at the top of the pressure relief tank is unidirectionally connected to the inlet of the reflux valve box, the outlet of the reflux valve box is connected to the inner cavity of the inner tank, the inside of the reflux valve box is elastically sealed and slidably connected to the inner tank side with an outer sliding sleeve, and the outer sliding sleeve can open and close the inlet of the reflux valve box.

[0009] The use process of the technical solution of the present invention is as follows:

[0010] After sufficient chemical gas is stored in the inner tank, as the external environment temperature rises, the pressure of the gas in the inner tank will increase, resulting in adverse effects;

[0011] When the gas pressure in the inner tank rises to a certain level, it will push the deflation valve core in the elastic support state, so that the gas in the inner tank can enter the deflation valve box from the pneumatic box, and then enter the pressure relief tank in the initial empty state from the gas outlet of the deflation valve box;

[0012] When the gas pressure in the inner tank returns to a safe value, the gas pressure is balanced with the supporting elastic force of the gas relief valve core itself, causing the gas relief valve core to close automatically.

[0013] And because the temperature has limited effect on the change of the pressure value of the gas in the inner tank, the pressure of the gas released into the pressure relief tank will be lower than the pressure of the gas in the inner tank when it is fully stored;

[0014] In the process of the gas in the inner tank being discharged into the pressure relief tank, the pneumatic wheel will be driven to rotate, so that the pneumatic wheel drives the water wheel fan in the water wheel box to rotate through the transmission mechanism. The water wheel fan will form a flow thrust of the liquid after rotating, so that the coolant between the inner wall of the outer tank and the outer wall of the inner tank can enter the flowing state from the static state. After the coolant enters the flowing state, its cooling effect will be improved to a certain extent, so as to achieve the purpose of stabilizing and reducing the gas pressure in the inner tank;

[0015] The temporarily stored chemical gas in the pressure relief tank will be released when the gas in the inner tank is released in normal use. As the chemical gas in the inner tank is released in normal use, the gas pressure in the inner tank will drop. When the pressure of the gas in the inner tank drops to the position where the outer sleeve is elastically expanded, the gas pressure in the inner tank is less than the pressure of the gas in the pressure relief tank, which will cause the gas in the pressure relief tank to actively flow into the inner tank. As the chemical gas in the inner tank is released in normal use, the purpose of simultaneously emptying the inner tank and the pressure relief tank will be achieved.

[0016] By adopting the above technical solution, the present invention can achieve the following beneficial effects:

[0017] (1) The inner tank and the outer tank of the present invention form an inner and outer double tank structure. By filling cooling liquid between the inner wall of the outer tank and the outer wall of the inner tank, a certain buffering and cooling effect can be exerted on the surrounding environment of the inner tank;

[0018] (2) The discharge of the present invention adopts a non-direct discharge method, which will not cause pollution to the environment. When the pressure of the chemical gas in the inner tank is too high, it will push the relief valve core in the elastic support state, so that the outlet of the relief valve box is connected with the inner cavity of the pressure relief tank. Through a simple mechanical structure, safe discharge without pollution and waste can be achieved;

[0019] (3) When the chemical gas in the inner tank is discharged into the pressure relief tank, the pneumatic wheel can be driven to rotate, so that the pneumatic wheel can drive the rotation of the water wheel fan in the water wheel box through the transmission mechanism. After the water wheel fan rotates, the coolant located between the external water pipe and the outer wall of the inner tank and the inner wall of the outer tank can form a certain flow effect. After the cooling liquid flows, the cooling effect can be improved, and the cooling efficiency of the chemical gas in the inner tank can be improved;

[0020] (4) In the present invention, a reflux assembly is installed between the top of the pressure relief tank and the inner tank. By elastically sliding an outer sleeve inside the reflux valve box which is unidirectionally connected to the pressure relief tank, after the pressure of the chemical gas in the inner tank drops to a certain value, the chemical gas temporarily stored in the pressure relief tank can return to the inner tank for normal supply use.

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 without creative work are within the scope of protection of the present invention.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0035] like Figure 1-Figure 10 As shown, a gas safety release device for chemical equipment, the inner tank 103 in the main tank body component 1 is located in the inner middle of the outer tank 102, the outer wall of the inner tank 103 and the inner wall of the outer tank 102 are filled with coolant, the pressure relief tank 202 is located on one side of the outer wall of the outer tank 102, the two ends of the external water pipe 301 are respectively connected to the cavity between the outer wall of the inner tank 103 and the inner wall of the outer tank 102, the main pipe of the external water pipe 301 is connected to a water wheel box 303, and the interior of the water wheel box 303 is screwed with a water wheel fan 307;

[0036] The pneumatic box 405 is located on one side of the water wheel box 303, and the inner cavity of the inner tank 103 is connected to the air inlet end of the pneumatic box 405, a pneumatic wheel 409 is screwed inside the pneumatic box 405, a relief valve box 412 is connected to the air outlet end of the pneumatic box 405, the air inlet end of the pressure relief tank 202 is unidirectionally connected to the air outlet end of the relief valve box 412, and only allows gas to flow from the relief valve box 412 to the pressure relief tank 202. The inside of the relief valve box 412 is elastically sealed and slidably connected to the side of the pneumatic box 405 with a relief valve core 418, and the relief valve core 418 can open and close the air outlet end of the relief valve box 412, so that when the gas pressure in the inner tank 103 is too high, the relief valve core 418 can be pushed, so that the gas in the inner tank 103 can be safely discharged into the pressure relief tank 202 for temporary storage;

[0037] The outlet at the top of the pressure relief tank 202 is unidirectionally connected to the inlet of the return valve box 503, and the outlet of the return valve box 503 is connected to the inner cavity of the inner tank 103, only allowing gas to flow from the pressure relief tank 202 to the inner tank 103, and the inner part of the return valve box 503 is elastically sealed and slidably connected to the inner tank 103 side with an outer sleeve 514, and the outer sleeve 514 can open and close the inlet of the return valve box 503, and when the gas pressure in the inner tank 103 is normal, the outer sleeve 514 is in a closed position. As the gas in the inner tank 103 flows out normally, the gas pressure in the inner tank 103 decreases, which will cause the outer sleeve 514 to move to an open position, so that when the chemical gas in the inner tank 103 is released during normal use, the chemical gas temporarily stored in the pressure relief tank 202 will be automatically transported to the inner tank 103 after the gas pressure in the inner tank 103 is reduced to a certain value.

[0038] The specific structures of the main tank body component 1 and the pressure relief tank body component 2 are as follows: Figure 2 and Figure 3 As shown, a base 101 is fixedly installed on the outer bottom of the outer tank 102, and the inner tank 103 and the gas outlet joint 105 are connected to the inner tank 103 after passing through the side wall of the outer tank 102, and the gas inlet joint 104 and the gas outlet joint 105 are fixedly connected to the side wall of the outer tank 102, which can form a supporting and fixing effect between the outer tank 102 and the inner tank 103;

[0039] The bottom wall of the outer tank 102 is connected to a water outlet joint 106, the upper end of the side wall is connected to a water inlet joint 107, one end of the external water pipe 301 is connected to the water outlet joint 106, and the other end is connected to the water inlet joint 107;

[0040] The side connecting plate 201 is fixed to the outer side wall of the outer tank 102, and the pressure relief tank 202 is fixedly installed on the outside of the side connecting plate 201 through the clamp 203;

[0041] The upper part of one end of the pressure relief tank 202 is connected to a discharge connector 204, and the lower part of the other end is connected to a discharge connector 205;

[0042] A normally closed valve is installed in the discharge joint 205, so that the pressure relief tank 202 can be emptied under special circumstances.

[0043] The specific structure of the external pipe component 3 is as follows: Figure 4 and Figure 5 As shown, the outer fixing seat 302 is fixedly connected to the outer side wall of the outer tank 102, and the outer side of the water wheel box 303 is fixed to the outer fixing seat 302;

[0044] The inner bottom surface of the inner cavity of the water wheel box 303 is fixed with a water wheel shaft inner seat 304, and the inner top surface is fixed with a water wheel shaft outer seat 305. One end of the water wheel shaft 306 is rotatably connected to the inner bottom surface of the water wheel box 303, and the other end is sealed and screwed out from the outer bottom surface of the water wheel box 303. The water wheel fan 307 is plugged and fixed in the water wheel box 303.

[0045] In addition, a cooling liquid discharge and input system is installed in the main pipe of the external water pipe 301, which can automatically replace the cooling liquid with new one when the cooling liquid temperature is too high.

[0046] The specific structure of the pressure relief component 4 is as follows Figure 6 and Figure 7 As shown, the transmission box 401 is fixedly connected to the outer side of the water wheel box 303, the outer shaft end of the water wheel shaft 306 is plugged and fixed with a large gear 402, the outer side of the water wheel box 303 is also fixed with a pneumatic wheel shaft inner seat 403, the pneumatic box 405 is fixed to the outer side of the transmission box 401, the pneumatic box outer cover 406 is fixed to the outer end opening of the pneumatic box 405, the outer side of the transmission box 401 is also fixedly installed with a pneumatic wheel shaft outer seat 404, the pneumatic wheel shaft inner seat 403 is rotatably connected with a pneumatic wheel shaft 407, and the pneumatic wheel shaft 407 is sealed and screwed in the pneumatic wheel shaft outer seat 404 and the pneumatic box outer cover 406;

[0047] The pneumatic wheel 409 is inserted and fixed in the pneumatic wheel shaft 407;

[0048] A small gear 408 is also inserted and fixed in the pneumatic wheel shaft 407, and the small gear 408 is meshed with the large gear 402;

[0049] One end of the air release pipe 410 passes through the side wall of the outer tank 102 and is connected to the inner tank 103, and the other end is connected to the air inlet end of the pneumatic box 405;

[0050] The head end of the air relief valve box 412 is connected to an air relief valve inlet 415, and the side end is connected to an air relief valve outlet 416. The air relief valve inlet 415 is connected to the air outlet end of the pneumatic box 405, and the air relief valve outlet 416 is connected to the air relief inlet joint 204 through the air relief pipe 413;

[0051] A gas leakage check valve 414 is installed in the main pipe of the gas leakage pipe 413, which only allows gas to flow from the gas leakage valve outlet 416 to the leakage inlet joint 204;

[0052] The end opening of the air release valve box 412 is covered with a valve cover 417, a guide slide seat 420 is symmetrically fixedly installed in the main body of the valve cover 417, and a guide column 419 is symmetrically fixedly connected to the rear end of the air release valve core 418, and the guide column 419 is slidably connected in the guide slide seat 420;

[0053] An adjusting nut 421 is fixedly mounted in the middle of the main body of the valve cover 417, and an adjusting bolt 422 is threadedly connected in the adjusting nut 421. A top spring 424 is fixed in the middle of the rear end of the air release valve core 418, and a rotating plate 423 is fixed to the outer end of the top spring 424. The inner end of the adjusting bolt 422 contacts the outer end of the rotating plate 423.

[0054] The compression degree of the top spring 424 can be adjusted by screwing the adjusting bolt 422, so that the elastic supporting force of the top spring 424 on the air release valve core 418 can be adjusted, so that the air release valve core 418 can be matched with different gas pressures of chemical gases;

[0055] When the pressure of the chemical gas in the inner tank 103 rises to a certain level due to the external environment, it is enough to push open the relief valve core 418, so that the relief valve inlet 415 is connected to the relief valve outlet 416;

[0056] At this time, the chemical gas in the inner tank 103 will enter the pneumatic box 405 through the air release pipe 410, and enter the air release valve outlet 416 through the air release valve inlet 415, and finally enter the inner cavity of the pressure relief tank 202 through the air release pipe 413;

[0057] As the high-pressure gas flows in the pneumatic box 405, the pneumatic wheel 409 is driven to rotate, thereby driving the small gear 408 to rotate. The small gear 408 can drive the water wheel shaft 306 to rotate through the reduction ratio formed with the large gear 402, thereby driving the water wheel fan 307 in the water wheel box 303 to rotate, so that the coolant in the external water pipe 301 flows, and then the coolant connected between the external water pipe 301 and the inner wall of the outer tank 102 and the outer wall of the inner tank 103 flows, and the purpose of cooling can be achieved by accelerating the flow of the coolant;

[0058] After the pressure of the chemical gas in the inner tank 103 drops and returns to a safe value, the relief valve core 418 will be elastically pushed out again, sealing the relief valve outlet 416 and automatically cutting off the discharge channel between the inner tank 103 and the pressure relief tank 202.

[0059] The specific structure of the reflux component 5 is as follows: Figure 8 and Fig. 9 As shown, a reflux joint 501 is connected to the middle of the top of the pressure relief tank 202, and the reflux pipe 502 passes through the side wall of the outer tank 102 and is connected to the inner tank 103. A reflux pipe 505 is connected to the reflux joint 501, and a reflux inlet 504 is connected to the side wall of the reflux valve box 503. The outlet of the reflux pipe 505 is connected to the reflux inlet 504, and the outlet of the reflux valve box 503 is connected to the reflux pipe 502;

[0060] A reflux check valve 506 is also installed in the main pipe of the reflux pipe 505, which only allows gas to flow from the reflux joint 501 to the reflux inlet 504;

[0061] The end opening of the return valve box 503 is covered with a return valve cover 507, the rear end of the inner connecting seat 508 is symmetrically fixed with an inner sliding column 509, and the middle point of the main body of the return valve cover 507 is symmetrically fixed with a sliding seat 510, and the inner sliding column 509 is slidably connected in the sliding seat 510;

[0062] The front end of the inner connecting seat 508 is fixedly connected with an inner support tube 512, and an outer sleeve 514 is sleeved and fixed on the inner support tube 512. An outer opening 515 is opened in the side wall of the outer sleeve 514, and an inner opening 513 is opened in the side wall of the inner support tube 512;

[0063] One end of the compression spring 511 is fixed to the middle of the rear end of the inner connecting seat 508, and the other end is fixed to the inner side surface of the return valve cover 507;

[0064] The elastic supporting force formed by the compression spring 511 on the inner connecting seat 508 and the outer sleeve 514 can match the pressure of the chemical gas in the inner tank 103, so that after the pressure of the chemical gas in the inner tank 103 drops to a certain value, the outer sleeve 514 can move to the position where the outer port 515 is connected with the reflux inlet 504, so that the chemical gas temporarily stored in the pressure relief tank 202 can enter the inner tube of the inner support tube 512 from the reflux pipe 505, and flow back from the reflux pipe 502 to the inner cavity of the inner tank 103, completing the normal use of the released chemical gas temporarily stored in the pressure relief tank 202.

[0065] The specific structure of the linkage temperature measurement component is as follows: Fig.10 As shown, the top rotating seat 601 is fixedly connected to the middle part of the outer top of the outer tank 102, and the top rotating shaft 602 is rotatably connected in the top rotating seat 601;

[0066] One end of the arc-shaped elastic rotating plate 603 is fixedly connected to the top rotating shaft 602, and an outer roller 604 is installed on the inner surface of the other end, and the outer roller 604 is rollingly connected to the outer top of the inner tank 103;

[0067] A temperature detector 605 is also installed on the inner surface of the elastic rotating plate 603;

[0068] The outer shaft end of the pneumatic wheel shaft 407 is plugged and fixed with a pneumatic pulley 606, the upper end of the outer wall of the base 101 is fixed with a conversion seat 607, the top of the conversion seat 607 is rotatably connected with a conversion shaft 608, one end of the conversion shaft 608 is plugged and fixed with a pneumatic connecting pulley 609, and a pneumatic connecting belt 610 is sleeved and installed between the pneumatic connecting pulley 609 and the pneumatic pulley 606;

[0069] A top pulley 611 is inserted and fixed at the other end of the conversion shaft 608, and a center pulley 612 is inserted and fixed at the top end of the top rotating shaft 602. The top pulley 611 is perpendicular to the main surface of the center pulley 612, and a top connecting belt 613 is twistedly sleeved between the top pulley 611 and the center pulley 612;

[0070] The pneumatic connection belt 610 and the top connection belt 613 are both cylindrical in cross section, and are easy to maintain and have good smoothness;

[0071] The elastic rotary plate 603 is an engineering plastic with a certain elasticity, which can provide a certain buffer support for the rolling of the outer roller 604 on the top of the outer tank 102 and also has a certain protective effect on the temperature detector 605.

[0072] Preferably, pressure gauges 411 are installed in the side walls of the pneumatic box 405 and the return valve box 503 to facilitate the display of pressure values.

[0073] Here’s how it works:

[0074] The inner tank 103 inside the outer tank 102 is used to store high-pressure chemical gas. The coolant between the inner wall of the outer tank 102 and the outer wall of the inner tank 103 can cool down the high-pressure chemical gas in the inner tank 103 and stabilize the gas phase.

[0075] After sufficient chemical gas is stored in the inner tank 103, as the external environment temperature increases, the pressure of the gas in the inner tank 103 will increase, resulting in adverse effects;

[0076] When the gas pressure in the inner tank 103 rises to a certain level, it pushes the deflation valve core 418 in the elastic support state, so that the gas in the inner tank 103 can enter the deflation valve box 412 from the pneumatic box 405, and enter the interior of the pressure relief tank 202 in the initial empty state from the gas outlet end of the deflation valve box 412;

[0077] When the gas pressure in the inner tank 103 returns to a safe value, the gas pressure is balanced with the supporting elastic force of the gas relief valve core 418 itself, causing the gas relief valve core 418 to close automatically;

[0078] And because the temperature has a limited effect on the change in the pressure value of the gas in the inner tank 103, the pressure of the gas released into the pressure relief tank 202 will be lower than the pressure of the gas in the inner tank 103 in the full state;

[0079] In the process of the gas in the inner tank 103 being discharged into the pressure relief tank 202, the pneumatic wheel 409 is driven to rotate, so that the pneumatic wheel 409 drives the water wheel fan 307 in the water wheel box 303 to rotate through the transmission mechanism. The water wheel fan 307 rotates to form a flow thrust of the liquid, so that the coolant between the inner wall of the outer tank 102 and the outer wall of the inner tank 103 can enter a flowing state from a static state. After the coolant enters the flowing state, its cooling effect will be improved to a certain extent, so as to achieve the purpose of stabilizing and reducing the gas pressure in the inner tank 103.

[0080] The temporarily stored chemical gas in the pressure relief tank 202 will be released when the gas in the inner tank 103 is released in normal use. With the normal use and release of the chemical gas in the inner tank 103, the gas pressure in the inner tank 103 will drop. When the pressure of the gas in the inner tank 103 drops to the position where the outer sleeve 514 is elastically expanded, the gas pressure in the inner tank 103 is less than the pressure of the gas in the pressure relief tank 202, which will cause the gas in the pressure relief tank 202 to actively flow into the inner tank 103. With the normal use and release of the chemical gas in the inner tank 103, the purpose of simultaneously emptying the inner tank 103 and the pressure relief tank 202 is achieved.

[0081] When the pneumatic wheel 409 rotates, the pneumatic pulley 606 is also synchronously driven to rotate. The pneumatic pulley 606 drives the pneumatic connection pulley 609 to rotate through the pneumatic connection belt 610, so that the pneumatic connection pulley 609 can coaxially drive the top pulley 611 to rotate through the conversion shaft 608. The top pulley 611 drives the center pulley 612 to rotate through the top connection belt 613, so that the elastic rotating plate 603 can rotate around the top rotating shaft 602 as the center, and cooperate with the outer roller 604 to roll on the top of the outer tank 102, so as to smoothly drive the temperature detector 605 to perform multi-point surrounding detection on the top wall of the outer tank 102;

[0082] By detecting the temperature at different positions on the top wall of the outer tank 102, the ambient temperature during discharge can be monitored more conveniently, so that when the temperature is too high and automatic discharge cannot meet the safe storage requirements of the inner tank 103, manual intervention can be used to quickly and safely discharge the inner tank 103.
