Abstract
The utility model discloses a waste gas treatment and heat recovery device. The waste gas treatment and heat recovery device comprises a shell including a gas exchange chamber and a combustion chamber, an incinerator, a burner, catalyst beds and a pipe-type heat exchanger component. One end of the gas exchange chamber is communicated to an exhaust emission device, and the other end of the gas exchange chamber is communicated to the combustion chamber. The pipe-type heat exchanger component is installed inside the gas exchange chamber, wherein a pipe orifice of one end of the pipe-type heat exchanger component is communicated to a gas outlet end arranged on the incinerator, a pipe orifice of the other end of the pipe-type heat exchanger component is communicated to a gas outlet arranged on the shell. The incinerator is installed inside the combustion chamber, and a gas inlet of the incinerator is communicated to the gas exchange chamber. The burner is installed at the end of the incinerator, and the catalyst beds are installed inside the incinerator. The waste gas treatment and heat recovery device has the advantages that a pipe-type heat exchanger can not transform easily and can enlarge a heat exchange area, and prolong the time for the exchange between the waste gas and the hot gas in the pipe. The incinerator is of a split-type structure, so that the fire produced by the burner can be in direct contact with the waste gas and then the conversion efficiency is increased. The catalyst beds arranged in tandem mode enable the catalytic effect to be optimum, reduce the blocking phenomenon, and prolong the service life.
