Abstract

A heat recovery device for a gas curing chamber is characterized in that a fin plate is arranged in the heat recovery device; an air inlet pipe on the upper part of the heat recovery device is connected with a main box body; a pneumatic valve is respectively mounted on the upper part and the lower part of the air inlet pipe; an air outlet pipe is mounted on the lower part of the heat recovery device; a mixed flow fan is mounted in the air outlet pipe; and an outlet of the mixed flow fan is connected with an auxiliary box body. The heat recover device for the gas curing chamber is economic and practical, simple in structure, and convenient to manufacture, and can improve the energy utilization efficiency, lower the operation cost of enterprises, and conform to the policies of energy conservation and emission reduction.

Description

technical field [0001] The invention relates to a heat recovery device, in particular to a heat recovery device for recycling high heat discharged from a burner. The device is suitable for heat recovery in a curing chamber in a combustion mode. Background technique [0002] The gas-fired curing chambers commonly used in the past such as figure 1 As shown, this curing chamber includes a main box 1, an auxiliary box 2 on the top of the main box, a burner 3 in the box, and the gas of the burner 3 is absorbed by the heat exchanger and discharged by the exhaust pipe 5. Heater absorbs heat insufficiently, has a large amount of heat loss, causes energy waste. Contents of the invention [0003] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a heat recovery device to improve the efficiency of energy use and achieve the goals of energy saving, emission reduction, low-carbon and environmental protection. [0004] To achieve the ...
