High-efficiency air temperature vaporizer

Abstract

The invention discloses a high-efficiency air temperature vaporizer, and relates to the field of vaporizers. An inlet and outlet connecting pipe is installed to connect an outlet with an inlet of thevaporizer, a negative pressure zone is formed in the middle throat portion through a venturi pipe, gas in the outlet of the vaporizer is sucked into the inlet of the vaporizer to be mixed, the heat exchange effect is improved, the heat exchange efficiency and heat exchange area of the vaporizer are improved, therefore, the heat exchange efficiency is improved, the heat exchange effect is better, and a one-way valve can ensure that liquid gas does not flow into the outlet of the vaporizer. The diameter of the middle throat portion of the venturi pipe is smaller than the diameter of the inlet ofthe vaporizer, the maximum diameters of the constricted section and the diffusing section of the venture pipe each are at least twice the diameter of the inlet of the vaporizer, the diameter of the inlet and outlet connecting pipe is smaller than the diameter of the middle throat portion of the venturi pipe, meanwhile, a pressurized air guiding assembly is arranged, and it can be effectively ensured that gas at the outlet of the vaporizer can be smoothly sucked into the inlet of the vaporizer for mixing through the negative pressure zone.

Description

technical field [0001] The invention relates to the technical field of carburetors, in particular to a high-efficiency air-temperature carburetor. Background technique [0002] The air-heated vaporizer uses the natural convection of air to heat the low-temperature liquid in the heat exchange tube to completely evaporate it into a gas. It is a high-efficiency energy-saving heat exchange equipment that integrates air-temperature and heating vaporization functions and can replace heating and vaporization products. A Chinese patent discloses an air-temperature vaporizer CN 207123200 U. This patented technology can facilitate the disassembly and replacement of the fixing plate, and can fasten finned tubes of different diameters. However, the heat transfer efficiency of this patented technology is low, and the heat transfer effect is low. It is also not ideal, and high-efficiency vaporization cannot be achieved. Therefore, those skilled in the art provide a high-efficiency air-tem...
