Methanol catalytic heating device and heating method

Abstract

The invention provides a methanol catalytic heating device and a heating method, relates to the technical field of heating equipment, and solves the technical problems of small heat exchange area andlow heat exchange efficiency. The methanol catalytic heating device comprises a heating barrel, an inner pipe and a coil pipe, wherein the inner pipe is arranged in the heating barrel; the coil pipe is spirally arranged between the inner pipe and the heating barrel in the axial direction of the heating barrel, and one end of the coil pipe is communicated with the inner pipe through a connecting pipe; the gap of the coil pipe is filled with catalyst; the heating device also comprises an air inlet device, an exhaust device, a heat exchange medium leading-in device and a heat exchange medium leading-out device, wherein the air inlet device and the exhaust device are both communicated with the inner cavity of the heating barrel; and the heat exchange medium leading-in device is communicated with the inner pipe or the coil pipe, and the heat exchange medium leading-out device is communicated with the other end of the coil pipe or the inner pipe. According to the invention, the heat exchangearea, the heat conduction medium reserve amount and the stroke of the heat conduction medium in the device are enlarged, and the heat exchange efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of heating equipment, in particular to a methanol catalytic heating device and a heating method. 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 conce...
