Prior art prior to the present invention

 The application of steam is very wide, and it is inseparable from the application of steam in industry, agriculture, households, and medical care. At present, steam is generated by heating water to boiling to generate steam. For example, in industrial waste heat generation methods such as boilers, civil boilers, electric boilers, etc., steam is generated by passing heat through a heat conductor to water, and water passes through natural convection. The steam is generated after the water reaches the boiling temperature. This method takes a long time to generate steam, consumes a lot of energy, and costs a lot. If steam is not needed, the boiling water will be cooled and the source energy will be wasted. In addition, this steam-generating boiler High water quality is required. Only soft water can be used. Hard water cannot be used. Water must be softened in advance. -Object of the invention

The nozzle of the atomizing nozzle 7 will generate atomized water and atomize. The water in the heating chamber 8 can be directly converted into high-pressure saturated steam by heating in various heating modes, and sent to the steam chamber 5 integrated with the heating chamber. Under the pressure of the heating and pressure pump or gear pump 6, The steam generated by the continuous atomization in the steam chamber 5 becomes the high-pressure saturated steam of the required pressure so as to be guided from the steam outlet 4 with a switch to the device to which the steam is applied; When the output is the same, the steam pressure in the steam chamber 5 can maintain the required steam pressure. There are several ways to heat the steam in the heating chamber 8: (1) Electric heating method; electric heating wire or electric heating rod can be used directly Heating the heating steel plate in the heating chamber 8 to a high temperature, so that the atomized water generated by continuous atomization becomes high-pressure saturated steam; (2) Open flame heating method :: Open flames such as petroleum gas, natural gas, coal or charcoal can be used The heating chamber 8 made of steel plate or stainless steel is directly heated, and a large amount of exhaust gas discharged from an open flame can be used to heat the heating chamber 8 or the steam 'chamber 5 through a heating pipe.

 Compared with the prior art, the present invention has the following advantages and beneficial effects: (1) The present invention can be made into a small volume, small source energy consumption, convenient and fast according to different required steam amounts and devices using steam. Device for generating high-pressure saturated steam by continuous water atomization heating. The generated steam can be used for steaming ironing clothes (vertical), cleaning furniture, cooking food in homes, disinfecting appliances in hospitals, and canteens and service industries. . If it is expanded, it can also be applied to steam-applied equipment in the food processing industry. (2) If the steam-applied device or equipment does not require steam, the power of the motor can be turned off and the water atomization will be stopped immediately. The heating chamber will be simultaneously Stopping the heating can stop generating high-pressure saturated steam, which can save a lot of source energy compared with the prior art; (3) The present invention is convenient and fast to generate high-pressure saturated steam, and the source energy is small.
