Description

Technical Field

[0001] The utility model relates to the technical field of vaporizers, in particular to a spraying device for an air-cooled vaporizer. Background Technique

[0002] An air-cooled LNG vaporizer is a vaporization device that relies on its own heat dissipation and absorption of heat from the external atmospheric environment to achieve the vaporization function. Its function is to convert liquid media into gaseous media. It is an energy-efficient heat exchange device that uses natural convection of air to heat low-temperature liquefied natural gas and completely vaporize it into natural gas. Liquefied natural gas (LNG) has begun to be gradually popularized in cities. Air-cooled LNG vaporizers have been gradually applied to LNG vaporization stations, LNG bottle group stations, LNG filling stations, L-CNG filling stations, LNG point supply (non-pipeline gas supply), etc. as energy-efficient heat exchange devices.

[0003] For example, the patent with the national authorization patent publication number CN217877213U discloses a spraying device for an air-cooled vaporizer, including an air-cooled sprayer. The air-cooled sprayer is mainly composed of three main structures: a spray main body frame and its components, a spray range diffusion pipe group, and a driving displacement component. The spray range diffusion pipe group and the driving displacement component are both installed on the spray main body frame and its components. The spray range diffusion pipe group and the driving displacement component are meshed and connected, and the spray range diffusion pipe group and the driving displacement component cooperate with each other. The spray range diffusion pipe group and the driving displacement component of the utility model cooperate with each other, and can drive the spray range diffusion pipe group to lift and make a small-range rotational movement through the driving displacement component. Through the driving displacement component, the spray range of the device can be further expanded. Secondly, the driving displacement component is convenient for realizing two spraying methods of expanding the range.

[0004] However, in the process of spraying and cooling the air-cooled vaporizer with the above-mentioned spraying device for an air-cooled vaporizer, it is unable to automatically detect whether the current temperature of the air-cooled vaporizer exceeds the set safety range to achieve the purpose of automatic spraying and cooling. As a result, the temperature cannot be effectively controlled, and untimely temperature adjustment will cause the equipment to frequently be in an extreme temperature state, accelerating the aging and damage of the equipment and shortening its service life. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a spraying device for an air-cooled vaporizer to solve the problem that in the process of spraying and cooling the air-cooled vaporizer, it is unable to automatically detect whether the current temperature of the air-cooled vaporizer exceeds the set safety range as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] Air-temperature vaporizer spraying device, comprising: a connecting frame, an air-temperature vaporizer body is fixedly installed inside the connecting frame, one end of the connecting frame is fixedly installed with a connecting plate, one end of the connecting plate is fixedly installed with a spraying mechanism, the spraying end of the spraying mechanism is fixedly installed on the upper surface of the connecting arm at an angle of 30° downward, and the connecting arm is fixedly installed on the upper surface of the connecting frame.

[0008] Preferably, the spraying mechanism includes a water-passing plate, and two groups of the water-passing plates are fixedly installed on the upper surface of the connecting arm at an angle of 30° downward, so that the two groups of the water-passing plates face both sides of the air-temperature vaporizer body. One end of the water-passing plate is fixedly installed with an atomizing nozzle, and the atomizing nozzle is communicated with the water-passing plate. The other ends of the two groups of the water-passing plates are communicated and installed with a Y-shaped three-way pipe.

[0009] Preferably, the Y-shaped three-way pipe is sleeved inside a collar, and the collar is fixedly installed at one end of the connecting plate.

[0010] Preferably, the lower end of the Y-shaped three-way pipe is communicated and installed with the water inlet of a water pump, the water pump is fixedly installed on the upper surface of a mounting plate, and the mounting plate is fixedly installed at one end of the connecting frame.

[0011] Preferably, the electric control end of the water pump is controlled by a controller, the controller is fixedly installed at one end of a triangular plate, and the triangular plate is fixedly installed at one end of the connecting plate;

[0012] Wherein, one end of the triangular plate is fixedly installed with a temperature sensor, the temperature sensing end of the temperature sensor penetrates through the triangular plate and extends into the air-temperature vaporizer body, and the signal transmitting end of the temperature sensor is connected with the signal receiving end of the controller.

[0013] Preferably, the models of the temperature sensor and the controller are Omega PR-10 and Honeywell UDC3200 respectively.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] 1. Through the design of the connecting arm, connecting frame, ambient temperature vaporizer body, and spraying mechanism, when the ambient temperature vaporizer body is working, the spraying mechanism on one side of the connecting plate will continuously monitor the temperature change of the ambient temperature vaporizer body. Until the temperature of the ambient temperature vaporizer body exceeds the set safety range, the spraying mechanism will be activated. The spraying mechanism will spray water mist simultaneously from both sides above the ambient temperature vaporizer body. The water sprayed on the surface of the ambient temperature vaporizer body will quickly evaporate, taking away a large amount of heat, thereby reducing the temperature of the ambient temperature vaporizer body. As the temperature of the ambient temperature vaporizer body gradually drops back to the set safety range, the spraying mechanism will detect this change again and feedback the signal to the control system in the spraying mechanism to stop spraying. After the spraying system stops, the ambient temperature vaporizer body will continue to operate, and the spraying mechanism will continue to maintain a monitoring state, ready to start the spraying mechanism to achieve the purpose of cooling when the temperature exceeds the limit again. Furthermore, the entire process can be automatically managed by the control system without manual intervention. By monitoring the temperature of the ambient temperature vaporizer body in real time, the timely response of the spraying mechanism can be ensured. Through this self-detection function, the temperature of the ambient temperature vaporizer body can always be kept within the set safety range, reducing potential safety hazards caused by overheating or overcooling. Moreover, the equipment can be prevented from frequently being in extreme temperature states, reducing the thermal fatigue and wear of the equipment and extending its service life.

[0016] 2. Through the design of the water pump, controller, temperature sensor, water passing plate, and atomizing nozzle, when the ambient temperature vaporizer body is working, the temperature sensor inside the ambient temperature vaporizer body will continuously monitor the temperature of the ambient temperature vaporizer body. When the temperature of the ambient temperature vaporizer body exceeds the set safety range (usually set by the control system), the temperature sensor will send a signal to the controller. After receiving the temperature overlimit signal, the controller will start the water pump through the electric control end. The water pump will pump the external water source into the Y-shaped tee. The water source will enter the two groups of water passing plates through the Y-shaped tee. When the pressure in the water passing plates reaches a certain pressure value, it will be sprayed out from the atomizing nozzles. The water sprayed on the surface of the ambient temperature vaporizer body will quickly evaporate, taking away a large amount of heat, thereby reducing the temperature of the vaporizer. As the temperature of the ambient temperature vaporizer body gradually drops back to the set safety range, the temperature sensor will detect this change again and feedback the signal to the controller. The controller will judge that the temperature of the ambient temperature vaporizer body has returned to normal according to the feedback of the temperature sensor, and then stop the operation of the water pump to stop spraying. The ambient temperature vaporizer body will continue to operate, and the temperature sensor and controller will maintain a monitoring state, ready to start the water pump to achieve the purpose of spraying and cooling when the temperature exceeds the limit again. Through this self-detection function, the temperature of the ambient temperature vaporizer body can always be kept within the set safety range, ensuring that the ambient temperature vaporizer body always operates within the optimal temperature range and reducing the impact of temperature fluctuations on the vaporization process.

Detailed Description of the Preferred Embodiment

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 - 3 , the present utility model provides a technical solution:

[0023] As Figures 1 - 2 shown, an ambient temperature vaporizer spraying device includes: a connecting frame 1, an ambient temperature vaporizer body 101 is fixedly installed inside the connecting frame 1, a connecting plate 104 is fixedly installed at one end of the connecting frame 1, a spraying mechanism 2 is fixedly installed at one end of the connecting plate 104, the spraying end of the spraying mechanism 2 is fixedly installed on the upper surface of the connecting arm 102 at an angle of 30° downward, and the connecting arm 102 is fixedly installed on the upper surface of the connecting frame 1.

[0024] Through the design of the connecting arm 102, the connecting frame 1, the air-cooled vaporizer body 101, and the spraying mechanism 2, when the air-cooled vaporizer body 101 is working, the spraying mechanism 2 on one side of the connecting plate 104 will monitor the temperature change of the air-cooled vaporizer body 101 in real time. Until when the temperature of the air-cooled vaporizer body 101 exceeds the set safety range, the spraying mechanism 2 will be activated. And the spraying mechanism 2 will spray water mist simultaneously from both sides above the air-cooled vaporizer body 101. The water sprayed on the surface of the air-cooled vaporizer body 101 will quickly evaporate, taking away a large amount of heat, thereby reducing the temperature of the air-cooled vaporizer body 101. As the temperature of the air-cooled vaporizer body 101 gradually drops back to the set safety range, the spraying mechanism 2 will detect this change again and feedback the signal to the control system in the spraying mechanism 2 to stop spraying. After the spraying system stops, the air-cooled vaporizer body 101 will continue to operate, and the spraying mechanism 2 will continue to maintain the monitoring state, ready to start the spraying mechanism 2 to achieve the purpose of cooling when the temperature exceeds the limit again. Furthermore, the whole process can be automatically managed by the control system without manual intervention. And by monitoring the temperature of the air-cooled vaporizer body 101 in real time, the timely response of the spraying mechanism 2 can be ensured. And through this self-detection function, the temperature of the air-cooled vaporizer body 101 can always be within the set safety range, reducing the safety hazards brought by overheating or overcooling. Furthermore, it can avoid the equipment being frequently in extreme temperature states, reduce the thermal fatigue and wear of the equipment, and extend the service life.

[0025] As Figure 3 shown, the spraying mechanism 2 includes a water passing plate 206. Two groups of water passing plates 206 are fixedly installed on the upper surface of the connecting arm 102 at an angle of 30° downward, so that the two groups of water passing plates 206 face both sides of the air-cooled vaporizer body 101. One end of the water passing plate 206 is fixedly installed with an atomizing nozzle 207, and the atomizing nozzle 207 is communicated with the water passing plate 206. The other ends of the two groups of water passing plates 206 are communicated and installed with a Y-shaped three-way pipe 201.

[0026] The Y-shaped three-way pipe 201 is sleeved inside the collar 105, and the collar 105 is fixedly installed at one end of the connecting plate 104.

[0027] The bottom end of the Y-shaped three-way pipe 201 is communicated and installed with the water inlet of the water pump 202. The water pump 202 is fixedly installed on the upper surface of the mounting plate 103, and the mounting plate 103 is fixedly installed at one end of the connecting frame 1.

[0028] The electric control end of the water pump 202 is controlled by the controller 204. The controller 204 is fixedly installed at one end of the triangular plate 203, and the triangular plate 203 is fixedly installed at one end of the connecting plate 104;

[0029] One end of the triangular plate 203 is fixedly installed with a temperature sensor 205. The temperature sensing end of the temperature sensor 205 penetrates through the triangular plate 203 and extends into the ambient temperature vaporizer body 101. The signal transmitting end of the temperature sensor 205 is connected to the signal receiving end of the controller 204.

[0030] The models of the temperature sensor 205 and the controller 204 are Omega PR-10 and Honeywell UDC3200 respectively.

[0031] Among them, the ambient temperature vaporizer body 101 can be a low-pressure vaporizer of model GKQ-100 or a high-pressure vaporizer of model GKQ-600.

[0032] Through the design of the water pump 202, the controller 204, the temperature sensor 205, the water passing plate 206 and the atomizing nozzle 207, when the ambient temperature vaporizer body 101 is working, the temperature sensor 205 in the ambient temperature vaporizer body 101 will monitor the temperature of the ambient temperature vaporizer body 101 in real time. When the temperature of the ambient temperature vaporizer body 101 exceeds the set safe range (usually set by the control system), the temperature sensor 205 will send a signal to the controller 204. After receiving the temperature over-limit signal, the controller 204 will start the water pump 202 through the electric control end. The water pump 202 will pump the external water source into the Y-shaped tee 201. The water source will enter the two groups of water passing plates 206 through the Y-shaped tee 201. When the pressure in the water passing plate 206 reaches a certain pressure value, it will be sprayed out from the atomizing nozzle 207. The water sprayed on the surface of the ambient temperature vaporizer body 101 will quickly evaporate, taking away a large amount of heat, thereby reducing the temperature of the vaporizer. As the temperature of the ambient temperature vaporizer body 101 gradually drops back to the set safe range, the temperature sensor 205 will detect this change again and feedback the signal to the controller 204. The controller 204 will judge that the temperature of the ambient temperature vaporizer body 101 has returned to normal according to the feedback of the temperature sensor 205, and then stop the operation of the water pump 202 to stop the spraying. The ambient temperature vaporizer body 101 will continue to operate, and the temperature sensor 205 and the controller 204 therein will remain in a monitoring state, ready to start the water pump 202 to achieve the purpose of spray cooling at any time when the temperature exceeds the limit again. Through this self-detection function, it can ensure that the temperature of the ambient temperature vaporizer body 101 is always within the set safe range, ensure that the ambient temperature vaporizer body 101 always operates within the best temperature range, and reduce the influence of temperature fluctuations on the gasification process.

[0033] Summarize and sort out the working steps of this solution according to the above technical solution: When the air-cooled vaporizer body 101 is working, the temperature sensor 205 inside the air-cooled vaporizer body 101 will monitor the temperature of the air-cooled vaporizer body 101 in real time. When the temperature of the air-cooled vaporizer body 101 exceeds the set safety range (usually set by the control system), the temperature sensor 205 will send a signal to the controller 204. After receiving the temperature overlimit signal, the controller 204 will start the water pump 202 through the electric control end. The water pump 202 will pump the external water source into the Y-shaped tee 201. The water source will enter the two groups of water passing plates 206 through the Y-shaped tee 201. When the pressure in the water passing plates 206 reaches a certain pressure value, it will be sprayed out from the atomizing nozzles 207. The water sprayed on the surface of the air-cooled vaporizer body 101 will quickly evaporate, taking away a large amount of heat, thereby reducing the temperature of the vaporizer. As the temperature of the air-cooled vaporizer body 101 gradually drops back to the set safety range, the temperature sensor 205 will detect this change again and feedback the signal to the controller 204. The controller 204 will judge that the temperature of the air-cooled vaporizer body 101 has returned to normal according to the feedback of the temperature sensor 205, and then stop the operation of the water pump 202 to stop the spraying. The air-cooled vaporizer body 101 will continue to operate, and the temperature sensor 205 and the controller 204 therein will remain in a monitoring state, ready to start the water pump 202 at any time when the temperature exceeds the limit again to achieve the purpose of spraying and cooling.

[0034] In summary: Through this self-detection function, it can ensure that the temperature of the air-cooled vaporizer body 101 is always within the set safety range, ensure that the air-cooled vaporizer body 101 always operates within the optimal temperature range, and reduce the impact of temperature fluctuations on the gasification process.
