Problems solved by technology

Patent CN108050501A discloses an internal spray type induction heating vertical steam generating device. The spray device in the barrel shortens the steam production time after the water is sprayed and atomized. However, there is heat transfer due to film boiling. In addition, scale is easy to deposit on the heating surface, which easily hinders heat transfer and reduces efficiency

Embodiment 1

[0034] Such as figure 1 , a spray adsorption steam generating device, the device includes a working chamber 1 and a water mist spraying unit located in the working chamber for forming atomized droplets; a metal porous adsorption unit for capturing atomized droplets and absorb heat radiation; the high-temperature radiation heating unit is set opposite to the water mist spray unit, and heats the liquid in the metal porous adsorption unit through heat radiation. The atomized liquid droplets formed by the water mist spray unit hit the surface of the metal porous adsorption unit and spread to the whole metal porous adsorption unit. After absorbing heat radiation, this part of water evaporates into water vapor8.

[0035] As a specific embodiment, the water mist spray unit includes a water tank 2, a water delivery pipe 3 connected to the water tank 2, and a plurality of groups of nozzles 4 installed on the water delivery pipe 3 for producing mist droplets. Above 200, the pore size r...

Abstract

The invention relates to a spraying adsorption type steam generating device, which comprises a working bin, a water mist spraying unit, a metal porous adsorption unit and a high-temperature radiation heating unit, wherein the water mist spraying unit is used for forming atomized liquid drops; the metal porous adsorption unit is used for capturing the atomized liquid drops and absorbing heat radiation; the high-temperature radiation heating unit is arranged opposite to the water mist spraying unit; the atomized liquid drops formed by the water mist spraying unit collide with the surface of the metal porous adsorption unit and are diffused to the whole metal porous adsorption unit; and after heat radiation is absorbed, the water is evaporated into steam. The device provided by the invention can quickly obtain steam including high-temperature steam and low-temperature steam; the steam quantity can be controlled by the flow of a nozzle as required, and no water is accumulated; boiling phase change occurs in a metal porous medium layer, so that heat transfer deterioration caused by membrane boiling is avoided; liquid is not in direct contact with a heating surface, and water scale deposits in the metal porous medium layer and does not cover the heating surface, so heat transfer is not affected.

Description

technical field [0001] The invention relates to the technical field of steam generation, in particular to a spray adsorption type steam generation device and its application. Background technique [0002] In food processing, disinfection and sterilization in the food machinery industry, ironing in the textile industry, and biological equipment industry, steam generators are essential equipment. Along with the wide application of steam generating devices in various industries, the production of various steam generating devices has also been promoted. [0003] Existing steam generating devices can be divided into the following types: (1) Dry type: water flows inside the tube, heating medium is outside the tube, and liquid water is used at the tube inlet. High-temperature flue gas and electromagnetic induction eddy current heat can be selected as heat sources. After the medium is heated, all steam is generated at the outlet, such as a direct-injection household steam oven; (2)...
