Detachable water bath type gasifier

Abstract

The invention relates to the technical field of gasifiers, in particular to a detachable water bath type gasifier. The gasifier comprises a shell, a cover and a heat exchange pipeline; an opening is formed in the top of the shell, the cover and the shell are matched and are detachably connected, a heating medium inlet, a heating medium outlet, a liquid inlet and a gas outlet are formed in the topface of the cover, the heat exchange pipeline comprises a liquid inlet pipe and a spiral pipe, the spiral pipe surrounds the interior of the shell with the perpendicular centre line of the shell as the surrounding center line, the liquid inlet pipe is vertically arranged in the shell, the bottom end of the liquid inlet pipe extends to the bottom in the shell, a top end pipe opening of the liquid inlet pipe is connected with the liquid inlet, a bottom end pipe opening of the liquid inlet pipe is connected with a bottom end pipe opening of the spiral pipe, a top end pipe opening of the spiral pipe is connected with the gas outlet, and a heat isolation structure or pipeline diameter thickening structure is arranged outside the liquid inlet pipe. The cover and the shell are detachably connected, daily maintaining and overhauling are facilitated, the liquid inlet pipe of the heat exchange pipeline is specially designed, the reverse pressure difference is prevented from being generated, andfinishing of the complete gasification process of LNG in the whole heat exchange pipeline is ensured.

Description

technical field [0001] The invention relates to the technical field of gasifiers, in particular to a detachable water-bath gasifier. Background technique [0002] The water-bath vaporizer uses the hot water in the shell to heat and vaporize the low-temperature liquid immersed in the inner winding tube, so that the outlet gas temperature meets the user's process needs. [0003] Water bath vaporizers can be divided into the following three types according to different heating methods: [0004] 1. Electric heating water bath vaporizer. This product uses high-efficiency electric heating elements to heat the water in the shell side, so as to achieve heat exchange with the low-temperature gas in the winding tube. [0005] 2. Steam-type water-bath gasifier. This product uses steam to heat and gasify the low-temperature gas in the heat source tube to meet the needs of users. [0006] 3. Hot water circulation water bath vaporizer, this product directly uses surplus hot water to hea...

Problems solved by technology

[0007] However, regardless of the above-mentioned heating methods, the heat exchanger shell is an integral structure, that is, the shell-side heat exchange chamber, heat exchanger shell, heat exchanger bracket, and bracket base are formed as an integrated structure. , once the heat exchange chamber fails, the entire heat exchanger needs to be disassembled to repair the heat exchange chamber. Due to the large size of the heat exchange equipment, it is difficult to disassemble and assemble, and the maintenance is not only time-consuming and laborious, but also the maintenance cost is high.
