Description

Technical Field

[0001] The utility model relates to the technical field of natural gas gasification, in particular to a circulating energy-saving secondary gasification device. Background Art

[0002] The main component of liquefied natural gas is methane, which is the cleanest fossil energy on earth. During transportation, for safety and convenience, natural gas needs to be cooled and liquefied, and when it is transported and used by end customers, it needs to be gasified. At present, the gasification of liquefied natural gas is usually processed by a gasifier, but when the temperature is low, the surface of the gasifier is frosted and the liquefied natural gas cannot be completely gasified. Therefore, a water-bath water heater is usually used to gasify natural gas for the second time. For example, a heating device for improving the secondary gasification rate is recorded in the patent announcement number CN 212132027U. The scheme recorded therein improves the distribution mode and structural form of the gasification branch pipe, the spiral mode of the heating branch pipe and the direction of the heating water flow, which is conducive to the efficient absorption of heat by the liquefied natural gas flowing out of the liquid inlet pipe, so as to achieve the effect of rapid gasification. However, in this case, during the secondary gasification, part of the heat of the heating water pipe will be directly dissipated inside the tank, which cannot be fully utilized, and the hot water is not reused for the second time, resulting in energy waste.

[0003] Based on this, a circulating energy-saving secondary gasification device is now provided, which can eliminate the disadvantages of the existing devices. Utility Model Content

[0025] See also Figure 3The hot water vaporization mechanism 200 includes a heating pool 201, which is connected to the lower end of the right side wall of the tank body 101 through an inlet pipe 202, and the upper end of the left side wall of the tank body 101 is connected to a water outlet pipe 203. The inlet pipe 202 and the outlet pipe 203 are connected by four heating branch water pipes 204. The hot water is heated by the heating pool 201 and enters the tank body 101 through the inlet pipe 202. The heating branch water pipes 204 circulate the hot water. Then it flows out through the outlet pipe 203, and the four heating branch pipes 204 are respectively coiled around the gasification branch pipe 104. The heating branch pipes 204 are coiled around the gasification branch pipe 104 to achieve heating and gasification of the gasification branch pipe 104. The outlet pipe 203 is connected to the heating pool 201 through the return pipe 205. The return pipe 205 recovers the waste heat of the hot water and realizes heat energy circulation. Liquid pumps are provided on the inlet pipe 202 and the outlet pipe 203.

[0026] See also Figure 3-Figure 4 The hot air insulation mechanism 300 includes an air outlet 302 arranged at the upper end of the right side wall of the tank body 101, and the air outlet 302 is connected to the heating box 305 through an exhaust pipe 304. A suction fan 303 is fixedly connected at the position of the air outlet 302.

[0027] Example 2

[0028] The difference from Example 1 is that, please refer to Figure 4 A detection probe 306 fixedly connected to the exhaust pipe 304 is provided on the rear side of the suction fan 303.

Since the heating branch water pipe 204 is spirally wrapped around the gasification branch pipe 104, the natural gas in the gasification branch pipe 104 is heated and gasified. The hot air ejected from the air inlet hole 301 accelerates the gasification better. The setting of the return pipe 205 and the exhaust pipe 304 realizes the waste heat recovery of hot water and hot air, realizes the heat energy cycle, is more energy-saving and environmentally friendly, and when the hot gas circulates, the detection probe 306 detects the gas, which can timely discover whether the natural gas is leaking, so as to take corresponding measures and use it more safely.
