Referring to fig. 1-3, a water-bath type high-efficiency heat exchange device according to an embodiment of the present invention includes a cylinder 1, a flue gas discharge pipe 2 and a heat exchange tube bundle 33 are disposed in the cylinder 1, a heat exchange liquid 4 is stored in the cylinder 1, the heat exchange tube bundle 33 is immersed in the heat exchange liquid 4, and the flue gas discharge pipe 2 is located below the heat exchange tube bundle 33. The lower end of the heat exchange tube bundle 33 is provided with a low-temperature liquid inlet 5, the upper end of the heat exchange tube bundle 33 is provided with a gas outlet 6, the heat exchange tube bundle 33 sequentially forms a first section S1 and a second section S2 from bottom to top in the vertical direction according to the gasification process of the low-temperature liquid, and the distance between the heat exchange tubes 7 of the first section S1 is larger than that between the heat exchange tubes 7 of the second section S2. The heat exchange tube 7 is internally provided with a turbulence strip 8, and the turbulence strip 8 is twisted to form a spiral shape.
The utility model discloses a high-efficient heat transfer device of water bath formula passes through flue gas delivery pipe 2 and carries the high temperature flue gas in to heat transfer liquid 4, arouses rivers acutely to mix, has improved the heat exchange efficiency of the LNG among heat transfer liquid 4 and the heat exchanger tube bank 33 greatly. The first sections S1 with larger intervals of the heat exchange tubes 7 are more convenient for the heat exchange liquid 4 to flow among the heat exchange tubes 7, are not easy to freeze and bridge, and improve the heat transfer; the spiral specially-made turbulence strips 8 greatly improve the contact time of the LNG and the tube wall of the heat exchange tube 7, so that the LNG and the heat exchange liquid 4 can be fully contacted, and the gasification efficiency is improved.
The height of the barrel body 1 in the utility model is about 3500 mm, wherein the liquid level height of the heat exchange liquid 4 is 3300 mm. A liquid level meter is arranged in the cylinder body 1 to detect the liquid level. In this way, the heat exchange liquid 4 in the cylinder 1 has enough space for flowing and stirring, and heat transfer between the LNG in the heat exchange tube 7 and the heat exchange liquid 4 is promoted. The length of the cylinder body 1 is 10 m-10.3 m, and the heat exchange tube bundle 33 with larger length and the heat exchange liquid 4 with larger volume can be accommodated, so that 120000Nm is realized3And (4) gasifying with super-large flow.
And simultaneously, the utility model discloses in, the pipe diameter of cryogenic liquids import 5 and gas export 6 is much bigger than the pipe diameter of heat exchange tube 7, and simultaneously, the wall thickness of cryogenic liquids import 5 and gas export 6 is also much bigger. So, utilize the high wall thickness, reduce the expend with heat and contract with cold that the difference in temperature arouses, realize the difference in temperature compensation, guarantee heat transfer device job stabilization nature.
Further, the heat exchange tubes 7 of the first stage S1 and the second stage S2 are horizontally laid in the heat exchange liquid 4. The heat exchange tubes 7 of the first section S1 and the second section S2 are horizontally laid and are parallel to each other, so that the heat exchange liquid 4 can be kept stable in the process of flowing in front of the heat exchange tubes 7, and turbulence cannot be generated to influence the heat exchange effect.
Further, the heat exchange tubes 7 located at the first section S1 and the second section S2 have the same tube diameter. In the same way, the pipe diameters are the same, the space between the heat exchange pipes 7 is uniform, the heat exchange liquid 4 flows stably, and the heat exchange effect is uniform and stable.
Further, the interval d1 of the heat exchange tubes 7 adjacent to the first segment S1 in the vertical direction is 80 mm, and the interval d2 of the heat exchange tubes 7 adjacent to the second segment S2 in the vertical direction is 50 mm. Thus, the heat exchange liquid 4 in the first section S1 before the heat exchange tube 7 has a large flowing space and is in full contact with the heat exchange tube 7. The space between the second section S2 is smaller, more heat exchange tubes 7 can be arranged, and the heat exchange flow is improved.
Further, the flue gas discharge pipe 2 and the heat exchange pipe 7 are arranged in parallel and are evenly provided with a plurality of air injection holes 9. So, the high temperature flue gas that flue gas discharge pipe 2 discharged gets into heat transfer liquid 4, stirs heat transfer liquid 4, promotes heat transfer liquid 4 to flow to improve heat exchange efficiency.
Further, the spoiler 8 is in close contact with the inner wall of the heat exchange tube 7. So, LNG gets into heat exchange tube 7 back, can only follow the spiral channel between vortex strip 8 and the heat exchange tube 7 pipe wall and advance, improves the time of LNG and the contact of heat exchange tube 7, and then makes the heat of heat transfer liquid 4 fully transmit in LNG.
Further, the spoiler includes siphon section 10 and spoiler section 11, and siphon section 10 is straight form, and spoiler section 11 is the heliciform. After entering the heat exchange tube, the LNG passes through the straight siphon section instead of immediately entering the spiral structure. This avoids the creation of large turbulence in the LNG.
Further, the length of the siphon section is 150 mm, and the length of each section of the spiral of the spoiler 8 is 80-100 mm. Therefore, the turbulence strips 8 with the structure can ensure that the LGN smoothly and quickly passes through the heat exchange tube 7 and ensure that LNG fully absorbs heat in the heat exchange tube 7.
