Heat supply device based on methanol catalyst heating

Abstract

The invention provides a heat supply device based on methanol catalyst heating. The heat supply device is characterized by comprising a heat exchange tube, the center of the heat exchange tube is provided with a heating pipe, a heat exchange cavity is formed between the outer walls of the heating pipe and the heat exchange tube, the upper and lower two ends of the heat exchange cavity are providedwith heat exchange mouths correspondingly, a heat exchange medium is in and out from the heat exchange mouths to perform heat exchange with the heat exchange cavity, the heating pipe is internally provided with a plurality of layers of catalytic cakes and heat storage cakes in a stacked manner, the end faces of the catalytic cakes and the heat storage cakes are provided with a plurality of ventilation holes, and the catalytic cakes and the heat storage cakes are distributed at intervals in a laminated manner, the bottom of the heat exchange tube is connected with an air fan and a methanol spray head, the methanol spray head emits atomized methanol to be blown into the heat exchange tube to contact with the catalytic cakes along with air flow, and the methanol and the catalytic cakes perform chemical reaction inside the heat exchange tube to generate heat for the heat storage cakes and the heat exchange tube. The heat supply device based on the methanol catalyst heating has the beneficial effects that in the heat supply device, a methanol catalytic heater is a flameless heating device, a generated exhaust gas after the catalytic reaction is only carbon dioxide, and the heat supplydevice based on the methanol catalyst heating is reliable to use, safe and free of pollution.

Description

technical field [0001] The invention relates to a heater, in particular to a heating device based on methanol catalyst heating. Background technique [0002] At present, in various fields such as production and manufacturing, service industry, and people's livelihood in China, boilers are widely used to obtain heat energy. A boiler is a device that obtains heat by burning fuel, that is, by using the temperature of the flame to heat. The fuel includes natural gas, coal, fuel oil, firewood, biomass particles and methanol. Using these fuels for combustion and heating has the following defects: insufficient combustion reaction and incomplete combustion; moreover, harmful substances will be released, such as sulfur oxides, nitrogen oxides, carbon monoxide, fine particles, etc., which seriously affect the air quality and damage the environment. ; Although the combustion of natural gas is relatively clean, most of its pipeline network is concentrated in the center of the city, an...
