Two-stage air boosting type multipurpose low-energy-consumption high-flow high-temperature steam generator

Abstract

The invention belongs to high-temperature steam generation devices in the field of industrial cleaning and provides a two-stage air boosting type multipurpose low-energy-consumption high-flow high-temperature steam generator. The two-stage air boosting type multipurpose low-energy-consumption high-flow high-temperature steam generator is low in electricity consumption and quick in heating and has three functions including high-pressure water flushing, high-pressure air blowing and high-temperature steam blowing. In order to solve the problems of long preheating time, high energy consumption in operation, functional singleness, proneness to incrustation in a pressure vessel, waste of water resources and the like of an existing saturated steam generator, a boiler of the existing saturated steam generator is omitted; a high-pressure water pump is adopted for generating high-pressure water flow which enters a heating cavity; by adoption of an air pump combination in serial connection, high-pressure air is generated to be mixed with high-pressure water in the heating cavity so as to generate high-flow high-temperature steam by heating; a supersonic-frequency (10KHz-30KHz) inductance heating device is adopted for quick preparation of high-temperature steam; due to the fact that the high-pressure water pump and pistons and cylinder barrels of high-pressure air pumps of the air pump combination are made of ceramic materials, rust prevention and abrasion resistance are realized.

Description

technical field [0001] The invention belongs to a novel multi-purpose high-temperature steam generating device applied in the field of industrial cleaning. Background technique [0002] Heated saturated steam generators have been used in the existing industrial cleaning field. The basic principle is to use high-power electric heating tubes to continuously heat water in a closed pressure vessel to convert it to 180 degrees Celsius and above, and the pressure is about 10Mpa and above. of saturated steam. The water content of this steam is extremely low, and it can be used for scouring and cleaning of various workpieces. [0003] The existing above-mentioned heating type saturated steam generator has the following defects: the energy consumption is large during operation, usually the electric power is 36KW or above, and the use cost is high; the working medium state conversion is carried out in the pressure vessel, which is easy to generate scale and requires frequent maintena...

Problems solved by technology

[0003] The existing above-mentioned heating type saturated steam generator has the following defects: the energy consumption is large during operation, usually the electric power is 36KW or above, and the use cost is high; the working medium state conversion is carried out in the pressure vessel, which is easy to generate scale and requires frequent maintenance and maintenance. Inspection, the use requirements are high; at the end of the work, in order to reduce scale, it is usually necessary to discharge the residual water directly, resulting in long-term waste of water resources and pollution to the environment; the warm-up time at the beginning of work is too long, and the working fluid is heated from liquid It takes about 30 minutes to reach the saturated steam state, and the use efficiency is affected

Single function, can only use saturated steam to complete the work
