Description
Technical field
The utility model relates to a kind of catalytic combustion system.
Background technology
The waste gas of current many industries generally adopts catalytic combustion to handle.Its basic principle is that the waste gas that will contain a large amount of solvents carries out flameless combustion by the effect of catalyst, produces a large amount of heat energy, simultaneously waste gas is changed into C02 and H20.
In traditional organic waste gas catalytic combustion equipment, gas enters catalytic combustion equipment from air inlet, after the purification of heat exchanger, electrothermal tube and Catalytic Layer, directly enter atmosphere, mainly there is following shortcoming in it: (1) heat exchanger generally adopts heat pipe, hot plate or heat storage, particularly adopt heat storages in the catalytic combustion equipment of handling big air quantity, weight of equipment is big, heat exchange is inhomogeneous and temperature is unstable more; (2) the burning of gas heat behind the catalytic combustion can not take full advantage of, and the gas temperature that enters atmosphere is higher; (3) the electrothermal tube centralized arrangement is in the upper and lower part of Catalytic Layer, or electrothermal tube buried is placed in the Catalytic Layer, and the efficiency of heating surface is relatively poor relatively, and temperature control point is few; (4) equipment adopts monolithic construction (welding of steel structure) usually, is unfavorable for catalyst and electrothermal tube etc.
Maintenance, replacing; (5) exhaust-gas treatment is unclean, enters air and pollutes.
