Steam generating device with steam recovery function and vapor-liquid separation function

Abstract

The invention discloses a steam generating device with a steam recovery function and a vapor-liquid separation function. The device comprises a steam regeneration tank, an electric heating device andan air return pipe; the top of the steam regeneration tank is connected with a regenerated steam extraction pipe, the regenerated steam extraction pipe is connected with and communicates with a steamoutput pipeline of a steam boiler, and the bottom of the regenerated steam extraction pipe is provided with a steam regeneration tank pollution discharge interface; the electric heating device is arranged at the lower side part of the steam regeneration tank and extends into a tank cavity; one end of the air return pipe is fixed to the side part of the steam regeneration tank, and the middle partand the other end of the air return pipe are connected with a steam utilization device through branch pipes; and the device is characterized by further comprising a vapor-liquid separation mechanism which is arranged in the tank cavity, and one end of the air return pipe extends to the vapor-liquid separation mechanism and is in a state of being protected by the gas-liquid separation mechanism. According to the device, the utilization effect of the recovered steam is improved; the steam production efficiency of the steam regeneration tank is improved, and the electric energy consumption of thesteam regeneration tank is saved; a recovery pipe is prevented from being affected by the steam pressure of the steam regeneration tank, so that the recovered steam can be smoothly introduced into the steam regeneration tank while the vapor-liquid separation is carried out on the recovered steam; and the structure is simple, and manufacturing and maintenance are convenient.

Description

technical field [0001] The invention belongs to the technical field of auxiliary facilities for textile and garment finishing, and in particular relates to a steam generating device with functions of steam recovery and vapor-liquid separation. Background technique [0002] The aforementioned steam generating device with steam recovery and vapor-liquid separation functions is set up with the steam boiler (also called "main boiler", the same below) when in use, and is connected and communicated with the steam output pipeline of the steam boiler to serve as a steam boiler. The boiler's additional steam supply device or auxiliary steam supply device provides technical support for the energy saving of the steam boiler; the typical example of the textile and garment finishing mentioned above is the use of steam irons to iron garments or similar knitted textile products. [0003] As known in the industry, due to the large amount of redundant steam generated during the operation of ...

Problems solved by technology

[0005] CN102200273B recommends "waste heat recovery system for hybrid energy environment-friendly steam generator". Although this patent can fulfill the technical effects recorded in paragraphs 0013 to 0020 of its description, it is redundant for the recovery of steam generating devices used as textile and garment finishing. Steam is not apocalyptic

[0006] CN106835660A provides "steam heating cycle system, steam generating device, and ironing machine". The achievement of this patent lies in: solving the technical problem that the prior art cannot recycle the steam in the return air pipe

This patent can faithfully embody the technical effects recorded in paragraphs 0021 to 0024 of the description, but there are the following unavoidable shortcomings: because it directly returns the excess steam to the water container through the steam recovery pipe (the water container is essentially The above is the steam generating tank), and because of the electric heating tube at the bottom of the water container, the water container is also generating steam, so when the recovered steam is all introduced into the water container at once through the steam recovery tube, Then the steam pressure in the water container will be greater than the pressure of the steam return pipe, so that the steam in the steam recovery pipe cannot enter the water container. In this case, the function of the steam recovery pipe is better than nothing or even useless
