Embodiment Construction

[0083] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0084] like figure 1As shown, the membrane steam generator in this embodiment is mainly composed of a water supply pipeline, a membrane evaporation tube 3, and a steam outlet and return water pipeline. The water supply pipeline includes a water supply main pipe 1 and a water supply branch pipe 2. Flow to the end of the water supply branch pipe 2, and keep flowing in one direction without dead ends. The steam outlet and return water pipeline includes a steam outlet and return water main pipe 5 and a steam outlet and water return branch pipe 4 . One end of the film evaporator tube 3 is connected to the main water supply pipe 1 and the water supply branch pipe 2, and the other end is connected to the steam outlet and return water main pipe 5 and the steam outlet and return water branch pipe 4, and the water supply is distributed to the membrane...

Abstract

The invention relates to a film type steam generator. The film type steam generator comprises water supply pipelines, a film type evaporation pipe and steam outlet and water return pipelines, wherein the water supply pipelines comprise a main water supply pipeline and a water supply branch pipeline, and supplied water flows to the tail end of the water supply branch pipe from an inlet end of the main water supply pipe; the steam outlet and water return pipelines comprise a main steam outlet and water return pipe and a steam outlet and water return branch pipe; one end of the film type evaporation pipe is connected with the main water supply pipeline or the water supply branch pipeline, and the other end of the film type evaporation pipe is connected with the main steam outlet and water return pipe or the steam outlet and water return branch pipe; steam in the steam outlet and water return branch pipe moves upwards, is output from a high-position steam outlet end and is merged into the main steam outlet and water return pipe, and returned water moves downwards and is merged into the main steam outlet and water return pipe from a low-position water return end; steam in the main steam outlet and water return pipe further moves upwards and is separated from the returned water and finally output from a steam output port, the returned water further moves down and is separated from the steam and finally output from a returned water outlet and merged into a water supply circulation tank, and circular water supply is realized after supplement. The film type steam generator combines advantages of a drum-type boiler and a once-through boiler, overcomes defects of the drum-type boiler and the once-through boiler and has popularization value.

Description

technical field [0001] The invention belongs to the technical field of steam generating equipment, and in particular relates to a membrane steam generator. Background technique [0002] Energy plays an important role in national economic life, and all walks of life cannot do without energy. Industrial steam (hereinafter referred to as steam) is a major energy carrier (heat energy, potential energy, kinetic energy); steam production equipment is mainly industrial boilers, which use various fuels such as coal, gas, fuel oil or biomass to Chemical energy is converted into thermal energy and potential energy (kinetic energy), which provides heat energy for production equipment, facilities and living facilities; in power plants, boilers provide potential energy heat energy for steam turbines, which are converted into kinetic energy of generating units to generate electricity. Therefore, as an industrial boiler for steam production, it plays an important role in industrial produc...
