Coil tube plus heat transfer fin steam generator

Abstract

The invention discloses a steam generator with coil tube and heat transfer fins. Its structural feature is that the inner container is spliced ​​by two heads, a coil tube is arranged under the heating inner container, and a heat transfer sheet is arranged inside the inner container. The water inlet on the periphery of the generator is connected with the first pressure gauge and the first safety valve, and the steam outlet is connected with the second pressure gauge, the second safety valve and the steam valve; there is a bracket on one side of the inner tank, and the bracket is composed of the first rib and the second rib. Two rib support. When the coil is heated during operation, the water in the coil generates saturated steam, which rises along the coil to the top of the liner, and the water continues to enter the coil to generate saturated steam to realize circulation, and the heat transfer fins are set inside the liner to increase the heat transfer area and realize Fast and efficient heat transfer, the steam required for work can be output through the external heat-insulating steam pipe at the steam outlet; the invention has simple structure, convenient operation, safety, reliability and high efficiency, and can be widely applied to steam drilling rigs in high altitude and glacier environments The invention solves the problems of long heating time, shallow drilling depth, low efficiency, bulky device and large volume of the steam generator of the existing steam drilling rig.

Description

technical field [0001] The invention belongs to a steam generating device of a steam drilling rig, in particular to a coiled tube plus heat transfer sheet type steam generator suitable for harsh environments such as high altitudes and glaciers. Background technique [0002] The steam generator (also known as the liner) currently used for steam drilling rigs in high-altitude areas is usually a fire tube type, which is cylindrical, and the heated flame passes through many heating tubes, and the space between the heating tubes is liquid; this type of steam generator exists The following problems: high energy consumption, high pollution to the glacier environment, low thermal efficiency, long heating time, heavy equipment, large volume, shallow drilling depth, and certain safety hazards. Therefore, the occasion and scope of its use are limited, and at the same time, the relevant scientific research work in high-altitude areas is greatly limited. Contents of the invention [0...
