Microwave steam generation technology

Abstract

The invention provides a microwave steam generation technology. The microwave steam generation technology includes the steps that firstly, water injection is conducted, a certain amount of water is injected into a microwave steam generation furnace, and water can be automatically supplemented according to the water level; secondly, microwave heating is conducted, wherein microwaves firstly act towater in a furnace, and the water temperature is increased to 40 DEG C to 50 DEG C from the normal temperature within 10 min, and in the process, the microwaves are used for heating water to generatesteam; thirdly, the microwaves are used for heating the steam, wherein the upper-layer microwaves are used for conducting multiple times of heating on the steam, heat insulation is conducted at the temperature of 100 DEG C to 120 DEG C, the temperature of the steam is increased, and the water content in the steam is reduced; and fourthly, exhausting is conducted, wherein the steam is conveyed froma steam outlet in the top of a furnace body. By means of the microwave steam generation technology, the microwaves are used for conducting multiple times of heating on the steam, the water content ofthe steam is reduced, the water in the furnace body does not need to be heated to 100 DEG C, and due to microwave layered heating, the heating time on water is shortened; energy consumption is greatly reduced; and due to the fact that the temperature of water in the furnace is low, pressurizing does not need to be conducted on the interior of the furnace, and the risk that people are scalded andthe furnace body is exploded is avoided.

Description

technical field [0001] The invention belongs to the field of steam generating equipment, and in particular relates to a microwave steam generating process. Background technique [0002] Existing steam generator boilers all use coal, oil, gas or electric heating as energy sources. They all use heat radiation and heat conduction to heat up and vaporize water to generate steam, and gradually heat the water body from the outside to the inside. During the heating process, the metal boiler pipe container, furnace wall and surrounding air are heated at the same time, and the heat loss is relatively large. And the rate of heat conduction is very low. This not only consumes a lot of fuel resources and causes environmental pollution, but also requires the construction of various large boilers, land occupation, boiler room construction, boiler installation, pipeline design and other engineering construction, resulting in long construction period, large investment, and high cost. high...

Problems solved by technology

First of all, although coal-fired and gas-fired steam generation is low in use cost, it is difficult to meet environmental protection requirements, and the degree of convenience in application is not high

The current problems of steam generators using electricity are: 1) high cost of use, 2) long time to produce steam, 3) unstable outlet temperature, 4) low safety factor

The main factors causing these problems are: because the current electric steam generators use electric heating tubes to heat the water, in this way, the heating tubes must first heat the water in the appliance to above 100 degrees to generate steam, and then The temperature of the steam is increased by the pressure in the appliance. In this way, the water is heated from 25 degrees to above 100 degrees to generate steam, and then the time to use the steam is longer, resulting in high cost of use and long time of steaming. The reason for adding water will also cause the outlet temperature to be unstable
