Technical Field

[0001] The utility model relates to the technical field of explosion vent wells, and more specifically, to an explosion vent well for a pottery jar storage. Background Art

[0002] A pottery jar storage is a special liquor storage facility, specifically for storing white liquor, especially high-quality raw liquor. These storages usually use pottery jars as storage containers because pottery jars have good air permeability and microporous structures, which are beneficial to the aging of white liquor and the improvement of liquor quality.

[0003] However, since a large amount of liquor is stored in the pottery jar storage and the liquor has special properties, once a liquor leakage accident occurs, it is very likely to cause a fire or explosion. Therefore, comprehensively improving the fire control, fire extinguishing, and explosion suppression capabilities of the pottery jar storage is a practical need for liquor enterprises to expand production and ensure safe production. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an explosion vent well for a pottery jar storage, which can effectively prevent the pottery jar storage from burning, spontaneous combustion, and explosion, and comprehensively improve the fire control, fire extinguishing, and explosion suppression capabilities of the pottery jar storage.

[0005] The embodiments of the utility model are realized through the following technical solutions:

[0006] An explosion vent well for a pottery jar storage includes a wellbore, a pressure relief roof plate, and an explosion isolation plate. A pressure relief opening is provided at the top of the wellbore. A plurality of buffer springs are arranged around the inner wall of the wellbore, and the other ends of the buffer springs are connected to the explosion isolation plate. A pressure relief roof plate is arranged at the top of the explosion isolation plate. The pressure relief roof plate is located inside the wellbore cavity, and the top wall of the pressure relief roof plate is located at the pressure relief opening. A support spring is arranged between the pressure relief roof plate and the wellbore. A gas release channel is provided on the pressure relief roof plate, and an electric valve is arranged on the gas release channel. A spraying device is arranged between the explosion isolation plate and the inner wall of the wellbore, and several explosion suppression units are arranged on the inner side wall of the explosion isolation plate.

[0007] Further, the explosion suppression unit includes a gas generator, a buffer, and an explosion suppressant storage, and a spray nozzle is arranged on the explosion suppressant storage.

[0008] Further, the spraying device includes a water storage device, a water inlet pipe, and a water outlet pipe respectively connected to the water storage device. The other end of the water inlet pipe extends outside the wellbore, and the other end of the water outlet pipe is connected to a spray head.

[0009] Further, several nozzles are arranged on the spray head.

[0010] Further, a limit frame is arranged on the inner top surface of the wellbore, and limit posts corresponding to the limit frame one by one are arranged on the pressure relief roof plate. The limit posts are slidably installed in the limit frame.

[0011] Further, an alarm lamp is also arranged on the outer side wall of the wellbore.

[0012] Further, an alcohol detector, a flame detector and a pressure sensor are arranged at the lower part of the explosion-proof plate.

[0013] The technical solution of the embodiment of the present utility model has at least the following advantages and beneficial effects:

[0014] In the present utility model, the wellbore, the buffer spring and the explosion-proof plate cooperate to reduce the impact force on the explosion-proof plate during an explosion and mitigate the explosion force. The wellbore, the pressure relief roof plate and the support spring cooperate. During an explosion, the air pressure pushes the pressure relief roof plate upwards, causing the top wall of the pressure relief roof plate to leave the pressure relief opening, enabling the pressure relief opening to communicate with the inside of the pottery jar storage, and the high-pressure gas can be discharged from the pressure relief opening in time to avoid secondary injuries to personnel caused by air pressure. The spraying device can spray water into the pottery jar storage to reduce the gas concentration, prevent the flame from burning or extinguish the flame, and the explosion suppression unit can suppress and absorb the flame energy to extinguish the flame. In addition, when it is detected that the alcohol concentration in the pottery jar storage is relatively high and alcohol is volatile, the air release channel can also be opened through the electric valve to communicate the air release channel with the outside and discharge the gas in the pottery jar storage to avoid the explosion of the pottery jar storage. The cooperation of each part can effectively prevent the pottery jar storage from burning, spontaneous combustion and explosion, and comprehensively improve the fire control, fire extinguishing and explosion suppression capabilities of the pottery jar storage.

[0023] Embodiment 1

[0024] As Figure 1As shown in the figure, this embodiment provides a venting well for a pottery jar storage, which includes a wellbore 1, a pressure relief roof 2, and an explosion isolation plate 3. A pressure relief opening is provided at the top of the wellbore 1. A plurality of buffer springs 4 are arranged around the inner wall of the wellbore 1, and the other ends of the buffer springs 4 are connected to the explosion isolation plate 3. The pressure relief roof 2 is arranged on the top of the explosion isolation plate 3. The pressure relief roof 2 is located inside the wellbore 1, and the top wall of the pressure relief roof 2 is at the pressure relief opening. A support spring 5 is arranged between the pressure relief roof 2 and the wellbore 1. An air release channel 6 is provided on the pressure relief roof 2, and an electric valve 7 is arranged on the air release channel 6. A spraying device is arranged between the explosion isolation plate 3 and the inner wall of the wellbore 1, and a plurality of explosion suppression units 10 are arranged on the inner side wall of the explosion isolation plate 3.

[0025] The cooperation of the wellbore 1, the buffer springs 4, and the explosion isolation plate 3 can reduce the impact force on the explosion isolation plate 3 during an explosion and mitigate the explosion intensity. The cooperation of the wellbore 1, the pressure relief roof 2, and the support spring 5 causes the air pressure to push the pressure relief roof 2 upward during an explosion, making the top wall of the pressure relief roof 2 leave the pressure relief opening to connect the pressure relief opening with the inside of the pottery jar storage, so as to timely discharge the high-pressure gas from the pressure relief opening and avoid secondary injuries to personnel caused by air pressure. The spraying device can spray water into the pottery jar storage to reduce its gas concentration, prevent the flame from burning or extinguish the flame, and the explosion suppression unit 10 can suppress and absorb the flame energy to extinguish the flame. In addition, when it is detected that the alcohol concentration in the pottery jar storage is relatively high and alcohol is volatile, the electric valve 7 can also be used to open the air release channel 6 to connect the air release channel 6 with the outside and discharge the gas in the pottery jar storage to avoid the explosion of the pottery jar storage. The cooperation of each part can effectively prevent the pottery jar storage from burning, spontaneous combustion, and explosion, and comprehensively improve the fire control, fire extinguishing, and explosion suppression capabilities of the pottery jar storage.

[0026] In this embodiment, the explosion suppression unit 10 includes a gas generator, a buffer, and an explosion suppressant storage. A spray port is provided on the explosion suppressant storage. During use, the gas generator quickly releases gaseous substances, which enter the explosion suppressant storage after being adjusted by the buffer at the required gas release speed and extremely high turbulence, and are mixed with the explosion suppressant to form a powder-gas mixture, which is sprayed into the explosion suppression space through the spray port to form an explosion suppressant cloud with extremely high concentration, fully contact the flame surface, absorb the flame energy, terminate the combustion chain, and extinguish the flame, thereby terminating the continuous propagation of the flame surface in the confined space filled with explosive gas.

[0027] In this embodiment, the spraying device includes a water storage tank 11, a water inlet pipe 12 and a water outlet pipe 13 which are respectively connected to the water storage tank 11. The other end of the water inlet pipe 12 extends outside the wellbore 1, and the other end of the water outlet pipe 13 is connected with a spray head 14. During an explosion, the water in the water storage tank 11 is sprayed out through the water outlet pipe 13 and the spray head 14 to reduce the gas concentration, prevent the flame from burning or extinguish the flame. In addition, when it is detected that the alcohol concentration in the pottery jar storage is relatively high, water can be conveyed into the water storage tank 11 through the water inlet pipe 12, and then the water is sprayed out through the water outlet pipe 13 and the spray head 14 to reduce the alcohol concentration in the storage and prevent combustion or explosion. Valves are arranged on both the water outlet pipe 13 and the water inlet pipe 12. Through the cooperation of the air release channel 6 and the spraying device, when the alcohol concentration in the pottery jar storage is relatively high but does not reach the limit value, the gas can be discharged in advance or the leaked alcohol can be diluted, thereby effectively preventing its explosion or combustion.

[0028] In this embodiment, a plurality of nozzles 15 are arranged on the spray head 14. The cooperation of multiple nozzles 15 can expand the spraying area of water and improve the speed of preventing the flame from burning.

[0029] In this embodiment, a limiting frame 8 is arranged on the inner top surface of the wellbore 1, and limiting columns 9 corresponding to the limiting frame 8 one by one are arranged on the pressure relief top plate 2. The limiting columns 9 are slidably installed in the limiting frame 8. Among them, the maximum compression length of the support spring 5 is equal to the moving distance of the limiting column 9 in the limiting frame 8. During an explosion, after the air pressure impacts the pressure relief top plate 2, the support spring 5 compresses, the pressure relief top plate 2 moves, the limiting column 9 moves upward in the limiting frame 8. After the air pressure impact ends, the support spring 5 elongates to drive the pressure relief top plate 2 to reset, and the limiting column 9 moves downward in the limiting frame 8, which can reset the pressure relief top plate 2 in time after the explosion or impact, and the reset is rapid and accurate.

[0030] In this embodiment, an alarm lamp 19 is further arranged on the outer side wall of the wellbore 1. When it is detected that the alcohol concentration in the pottery jar storage is relatively high, the alarm lamp 19 can be triggered, and the alarm lamp 19 rings to remind the staff, which helps the staff to take preventive measures in time and avoid personal injury.

[0031] In this embodiment, an alcohol detector 15, a flame detector 16 and a pressure sensor 17 are arranged at the lower part of the explosion isolation plate 3. Among them, the alcohol detector 15, the flame detector 16 and the pressure sensor 17 can be connected to the control system, and the alarm lamp 19, the electric valve 7, the valves of the water inlet pipe 12 and the water outlet pipe 13 and the gas generator can also be connected to the control system. In this way, the air release channel 6, the spraying device and the explosion suppression unit 10 can be adjusted according to the detection signals, and the fire control, fire extinguishing and explosion suppression capabilities of the pottery jar storage can be improved.

[0032] The working principle of the explosion venting well of the pottery jar storage is as follows: When the alcohol detector detects a relatively high concentration in the pottery jar storage, after receiving the signal, the control system controls the electric valve 7 to open the air release channel 6 to discharge the gas. At the same time, the control system can also control the valves on the water inlet pipe 12 and the water outlet pipe 13 to open, spray water into the storage to reduce the alcohol concentration, and the alarm lamp 19 sounds to remind the staff to take corresponding preventive measures. During an explosion, the air pressure impacts the pressure relief roof 2, and the upward movement of the pressure relief roof 2 causes the pressure relief opening to open, allowing the high-pressure gas in the storage to be discharged from the pressure relief opening to achieve the purpose of pressure relief. At the same time, after the flame detector 17 detects the flame signal, the control system receives the signal and controls the gas generator to start, enabling the gas generator to quickly release gaseous substances. After being adjusted by the buffer, the gaseous substances enter the explosion suppressant storage at the required gas release speed and extremely high turbulence. After being mixed with the explosion suppressant to form a powder-gas mixture, it is sprayed from the nozzle into the explosion suppression space to form an explosion suppressant cloud with an extremely high concentration, fully contact the flame surface, absorb the flame energy, terminate the combustion chain, and extinguish the flame. At the same time, the water outlet pipe 13 and the nozzle 14 spray the water in the water storage 11 to reduce the gas concentration and prevent the flame from burning or extinguish the flame.

[0033] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, various modifications and changes can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
