Problems solved by technology

[0002] The low-temperature medium drawn from the low-temperature storage tank enters the air-bath vaporizer to be heated and vaporized. Since the temperature of the liquid medium initially reaches minus 196°C, when the traditional finned tube is used, the surface of the tube at the inlet of the fin is affected by the air There is moisture in the medium, and the low-temperature medium absorbs the heat in the atmosphere in this tube, and will condense on a thick ice layer, so that the heating and vaporization effect will drop sharply

Embodiment Construction

[0009] See figure 1 , Figure 2, the present invention includes a liquid inlet pipe 1, a finned heat exchange tube, and an air outlet pipe 7, and the finned heat exchange tube is a multi-section finned heat exchange pipe section that is connected and conducted through connecting pipes 4 and 6, along the flow of the liquid medium direction, the spacing between the finned heat exchange tube sections changes from large to small, and the number of fins increases from few to large. The finned heat exchange tube section includes heat exchange tube 2 with 4 fins, and the heat exchange tube with 4 fins The input end of the pipe section is connected in parallel with the liquid inlet pipe 1, and each heat exchange pipe section with 4 fins is connected to the heat exchange pipe section 3 with 8 fins and the heat exchange pipe section with 12 fins sequentially through the connecting pipe. Pipe sections 5 and 8 are brackets, and pipe sections 9 and 10 are flange covers respectively.

Abstract

The invention provides an improved difficult-frozen air-bath type carburetor, which can reach the effects that a finned pipe of the air-bath type carburetor is difficult to freeze, and ensure heating vaporization. The air-bath type carburetor comprises a liquid inlet tube, a fin type heat exchange tube, and an air outlet pipe. The air-bath type carburetor is characterized in that a plurality of sections of fin type heat exchange tubes are connected and communicated through connecting pipes, and the intervals between the fin type heat exchange tubes are decreased along the flow direction of liquid media.

Description

(1) Technical field [0001] The invention relates to the technical field of air-bath gasifiers, in particular to an improved air-bath gasifier that is not easy to freeze. (2) Background technology [0002] The low-temperature medium drawn from the low-temperature storage tank enters the air-bath vaporizer to be heated and vaporized. Since the temperature of the liquid medium initially reaches minus 196°C, when the traditional finned tube is used, the surface of the tube at the inlet of the fin is affected by the air There is moisture in the medium, and the low-temperature medium absorbs the heat in the atmosphere in this tube, and will condense on a thick ice layer, so that the heating and vaporization effect will drop sharply. (3) Contents of the invention [0003] In view of the above defects, the present invention provides an improved air-bath gasifier which is not easy to freeze, which can make the upper finned tubes of the air-bath gasifier not easy to freeze and ensur...
