Novel flow stabilized gasifier

Abstract

The invention relates to the technical field of gasifiers, in particular to the design of a novel flow stabilized gasifier. The novel flow stabilized gasifier comprises a supporting frame, heat transfer pipes and a supporting seat, the heat transfer pipes are mounted on the supporting frame and arranged in the transverse and longitudinal directions in an arrayed mode, and the supporting frame is mounted on the supporting seat. The heat transfer pipes comprise liquid inlets and air outlets, the liquid inlets are separately formed in the bottoms of two sides of the supporting frame, and the airoutlets are formed in the bottom of the middle of the supporting frame. By arranging the liquid inlets separately on two sides of the heat transfer pipes, the novel flow stabilized gasifier realizes that a liquid heat transfer medium can be poured from two sides and outflowed from the central part of the supporting frame, the heat exchange area of contacting with air is multiplied, the heat transfer efficiency is improved, the two sides of the gasifier frost and transfer heat at the same time, the stress of the gasifier is changed from single surface to double surfaces, the stress of four legsupports is balanced, and the adequate stability is ensured.

Description

technical field [0001] The present invention relates to large flow (generally refers to flow ≥ 5000NM 3 / h) In the technical field of air-temperature gasifier in the industrial gas or LNG industry, specifically design a new flow-direction stable gasifier. Background technique [0002] In the related technology of the gasifier, its working principle is usually that the ultra-low temperature liquid generally enters along the heat exchange tube on the same side of the gasifier, and then flows to the other side. The heat is exchanged, the temperature is gradually raised, and the gasification is completed, forming a gas close to the ambient temperature. [0003] However, when the cryogenic liquid is just delivered from the storage tank to the heat exchange tube of the vaporizer, due to the extremely low temperature, the water vapor in the air will quickly adhere to the outer wall of the heat exchange tube and form frost or ice, resulting in gas One side of the carburetor is ser...

Problems solved by technology

[0003] However, when the cryogenic liquid is just delivered from the storage tank to the heat exchange tube of the vaporizer, due to the extremely low temperature, the water vapor in the air will quickly adhere to the outer wall of the heat exchange tube and form frost or ice, resulting in gas One side of the carburetor is seriously icing, while the rest of the place is less icing, which causes the overall center of gravity of the carburetor to shift to the icing side, seriously affecting the stability of the carburetor

Especially in the event of strong wind or typhoon, since the center of gravity of the gasifier shifts to the icing side, it is likely to cause the legs of the gasifier to break, the anchor bolts on the other side to break or the foundation to tilt, seriously affecting The safety of the vaporizer
