Electromagnetic heat conversion assembly in electromagnetic heating type vapor generator

Abstract

The invention discloses an electromagnetic heat conversion assembly in an electromagnetic heating type vapor generator. The electromagnetic heat conversion assembly is arranged in a vapor generator body and comprises a heat preservation and heat insulation body and a columnar electromagnetic heat generator arranged in the heat preservation and heat insulation body. An electromagnetic induction coil pipe is arranged on the periphery of the electromagnetic heat generator. Outer-layer heating runners, middle-layer heating runners and a core heating runner are arranged in the electromagnetic heatgenerator. One end of the electromagnetic heat generator is a water inlet end, water flows in from the outer-layer heating runners, the other end of the electromagnetic heat generator is a vapor outlet end, and vapor is discharged out from the core heating runner. A flow concentration booster cavity is formed in the water inlet end, and primary flow concentration cavities are formed in the water outlet end. In the electromagnetic heat conversion assembly, through the manner that water cyclically flows from outside to inside, the electromagnetic heat conversion efficiency is high, heating is rapid, the output of high-temperature vapor is large, the flowing speed is high, no contaminant is discharged, energy saving and high efficiency are achieved, and use is convenient.

Description

technical field [0001] The invention belongs to the technical field of steam heating equipment, and in particular relates to an electromagnetic heat conversion component in an electromagnetic heating steam generator. Background technique [0002] Steam generators, commonly used equipment such as boilers, are mechanical devices that use the heat energy of fuel or other energy sources to heat water into hot water or steam. At present, most of the steam generators used in industrial workshops are boilers, which generate heat by burning coal or natural gas to heat water to generate water vapor. This method requires a dedicated boiler room, which occupies a large area, and at the same time, the combustion of fuel will generate a large amount of steam. harmful polluting gases.

Problems solved by technology

At present, most of the steam generators used in industrial workshops are boilers, which generate heat by burning coal or natural gas to heat water to generate water vapor. This method requires a dedicated boiler room, which occupies a large area, and at the same time, the combustion of fuel will generate a large amount of steam. harmful polluting gases

[0003] Specific to the existing industrial fields, such as the paper industry, large equipment requires a large amount of steam heating, and a steam boiler using a combustion medium must be added. Since the boiler is a special equipment, it needs to be operated and maintained by professionals and needs to be far away from the production area, so it is necessary to lay Longer transmission pipelines are costly, and the long-distance transmission pipelines bring large transmission losses. In addition, there are air pollution and PM2.5 emission problems due to the use of combustion media (usually coal or natural gas)

Larger boilers must also add environmental protection devices such as dust removal and flue gas desulfurization, and require frequent maintenance to ensure the effectiveness of the equipment, and the maintenance cost is relatively high

Moreover, the working characteristics of the boiler determine that it responds slowly to the steam demand of the equipment, and cannot be connected with the equipment control system

[0004] For some small industrial equipment, it needs fast steam heating (such as steam sterilization), which mostly adopts electric heating method, but due to the slow heating speed and long preheating time of resistance wire and infrared tube, it is not conducive to small batch batch type work, there are disadvantages such as high cost, large power consumption, high control difficulty, and fast aging speed
