Description

Technical Field

[0001] This utility model belongs to the field of vaporizer technology, specifically relating to a portable ambient temperature vaporizer. Background Technology

[0002] LPG (liquefied petroleum gas) / LNG (liquefied natural gas) tank trucks, as transport carriers of flammable and explosive media, require mobile venting and ignition systems to safely release and ignite residual or excessive hazardous media in emergency situations such as traffic accidents, tank leaks, and overpressure, in order to eliminate major safety hazards such as explosions, poisoning, and environmental pollution. A key aspect of emergency response is the efficient vaporization of liquid LPG or LNG into a gaseous state, providing a stable and clean gas source for subsequent safe combustion. However, existing vaporizers are mostly fixed, bulky, and difficult to move, making it difficult to quickly reach the accident site and commence operations. Furthermore, their low vaporization efficiency fails to meet the core requirements of "rapid response and reliable safety" in emergency rescue. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a portable ambient temperature vaporizer that is compact, easy to move, has high vaporization efficiency and built-in safety monitoring, specifically for emergency venting operations in LPG / LNG tanker accidents.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A portable ambient temperature vaporizer includes two rectangular frames with a heat dissipation pipe between them. The outer wall of the heat dissipation pipe has multiple heat dissipation fins. One end of the heat dissipation pipe is a medium inlet for connecting to the liquid phase valve of an emergency tanker truck. The other end of the heat dissipation pipe is a medium outlet connected to a gas-liquid separator via a flexible hose. The gas-liquid separator has an exhaust port at the top and a liquid drain port at the bottom. The gas-liquid separator is used to separate fully vaporized gas from incompletely vaporized droplets or impurities.

[0005] To further improve vaporization efficiency, the heat dissipation pipe includes N parallel straight pipes and N-1 U-shaped bends, where N≥2. Adjacent straight pipes are sealed and connected by the U-shaped bends to form a series path. Multiple heat dissipation fins are evenly distributed circumferentially on the outer wall of each straight pipe.

[0006] To further prevent danger caused by excessive pressure inside the gas-liquid separator, the gas-liquid separator is equipped with a pressure gauge for real-time monitoring of the internal pressure of the tank, and a switch valve is installed on the flexible hose at the medium outlet. The switch valve is used to manually or automatically cut off the passage according to the pressure value of the pressure gauge.

[0007] To further increase the heat exchange area between the heat sink and the air, the heat sink is made of aluminum alloy, and the radial length of the heat sink is 3-5 times the outer diameter of the straight pipe.

[0008] To facilitate the disassembly, replacement, and maintenance of components, and to enhance the strength of the heat dissipation pipes, a fixing clip is provided on the rectangular frame. The heat dissipation pipes are detachably installed on the rectangular frame via the fixing clip, and the ends of adjacent straight pipes are connected by a support clip.

[0009] To further improve portability and mobility, the bottom of the rectangular frame is equipped with multiple casters with braking function.

[0010] To improve the service life of the vaporizer, the gas-liquid separator is made of 316 stainless steel, and the flexible hose is made of low-temperature resistant stainless steel corrugated pipe.

[0011] Compared with the prior art, the present invention has the following beneficial technical effects: This invention employs a multi-straight-pipe series connection and a heat dissipation pipe structure with large-area heat sinks, increasing the heat exchange area by over 200% compared to a single-pipe structure. It achieves an LNG vaporization efficiency of up to 99.5% at -162℃, with liquid residue ≤0.1%, fully utilizing room temperature for heat exchange and producing a large vaporization volume (up to 20m³). 3 / h), to meet the combustion requirements.

[0012] This invention, by setting up a gas-liquid separator, can perform "gas-liquid separation" on the medium output from the heat dissipation pipe, accurately capture and remove trace amounts of incompletely vaporized liquid components, and ensure that the medium entering the downstream combustion gun is a highly pure gaseous state, thereby ensuring the safe and stable operation of the entire venting and ignition system and guaranteeing operational safety.

[0013] This invention, by installing universal wheels with braking function at the bottom of the frame, can quickly move the vaporizer to a safe area upwind of the tanker truck, greatly shortening the emergency response time; and by adopting an integrated design of heat dissipation pipe and gas-liquid separator, no additional pipeline assembly is required, reducing the number of operation steps at the accident site, further reducing the deployment time of the device, and adapting to the "golden period" of emergency response.

[0014] The gas-liquid separator of this invention is made of 316 stainless steel, which can withstand the pressure of the medium during the separation process (pressure rises after vaporization) and potential corrosion (such as trace sulfides in LPG), ensuring that the gas-liquid separator can operate reliably for a long time under harsh working conditions and avoiding failures caused by equipment damage.

[0016] The following detailed description illustrates the specific implementation method: Example

[0017] like Figure 1-3 As shown, a portable air-temperature vaporizer includes two rectangular frames 1, which serve as the main support. The four corners of the bottom of the rectangular frames 1 are equipped with casters 11 with braking function, so that the entire device can be easily moved.

[0018] A heat dissipation pipe 2 is provided between the two rectangular frames 1. The heat dissipation pipe 2 includes 6 parallel straight pipes 21 and 5 U-shaped bends 22. The 6 straight pipes 21 are evenly distributed in two rows and three columns. Adjacent straight pipes 21 are sealed and connected by U-shaped bends 22 to form a series path. Each straight pipe 21 has 8 heat dissipation fins 23 evenly distributed circumferentially on its outer wall. Two fixing clips 12 are welded and fixed to the upper inner side and lower inner side of the two rectangular frames 1, respectively. The fixing clips 12 are located between the ends of two adjacent straight pipes 21. The two ends of the fixing clip 12 are detachably clamped onto the heat sink 23 on the outer wall of the two straight pipes 21; a support clip 24 is provided between every four adjacent straight pipes 21 (arranged in 2×2), and the four ends of the support clip 24 are detachably clamped onto the heat sink 23 on the outer wall of the four straight pipes 21 to improve the overall strength of the heat sink 2; the heat sink 23 is made of aluminum alloy, and the radial length of the heat sink 23 is 3-5 times the outer diameter of the straight pipe 21 to increase the heat dissipation area and improve the vaporization efficiency.

[0019] One end of the heat dissipation pipe 2 is the medium inlet, which is equipped with a first quick connector 3 for connecting to the liquid phase valve of the tank truck. The other end of the heat dissipation pipe 2 is the medium outlet, which is connected to a gas-liquid separator 5 via a flexible hose 4. The gas-liquid separator 5 is used to separate fully vaporized gas from incompletely vaporized droplets or impurities. The upper part of the gas-liquid separator 5 is equipped with an exhaust port 51, which is connected to a second quick connector 52 for connecting to a combustion gun. The bottom of the gas-liquid separator 5 is equipped with a drain port 53, which is normally closed but can be opened to discharge unvaporized droplets when necessary. The gas-liquid separator 5 is also equipped with a pressure gauge 54 for real-time monitoring of the internal pressure of the tank. The flexible hose 4 at the medium outlet is equipped with a switch valve 55, which is used to manually or automatically cut off the passage according to the pressure value of the pressure gauge 54 (the figure shows the manual switch valve 55). In order to improve the service life of the vaporizer, the gas-liquid separator 5 is made of 316 stainless steel, and the flexible hose 4 is made of low-temperature resistant stainless steel corrugated pipe.

[0020] The specific implementation is as follows: During operation, the cryogenic liquid medium flows out of the tanker and enters the heat dissipation pipe 2 through the medium inlet. During the flow through the heat dissipation pipe 2, the medium exchanges heat with the air through the heat dissipation fins 23 and quickly absorbs heat and vaporizes. The vaporized gas (which may contain liquid droplets) enters the gas-liquid separator 5. The liquid settles to the bottom of the tank due to gravity, while the pure gas is delivered to the combustion gun from the exhaust port 51 at the top for combustion. The operator can understand the working status of the gas-liquid separator 5 by observing the reading of the pressure gauge 54. If the pressure rises abnormally, the switch valve 55 can be closed in time to cut off the gas supply and troubleshoot the fault.

[0021] This portable ambient temperature vaporizer, through its integrated and safety-focused design, delivers significant technological benefits: its bottom caster wheel 11 greatly enhances portability and enables rapid deployment; the heat dissipation pipe 2 with a large-area heat sink 23 fully utilizes ambient temperature for heat exchange, resulting in high and stable vaporization efficiency; the integrated gas-liquid separator 5, equipped with a pressure gauge 54 and a switching valve 55, allows for real-time pressure monitoring and separation of unvaporized droplets, effectively preventing overpressure and direct liquid discharge risks and ensuring operational safety; it addresses the core pain points of traditional emergency equipment in scenarios, such as difficulty in assembly, low efficiency, and high risk, and features convenient mobility, rapid deployment, high vaporization efficiency, safety, reliability, and long service life, making it particularly suitable for mobile venting operations in emergency response to LPG / LNG tanker accidents.
