Detailed Description

The present invention is further described below with reference to the following drawings, which are only for illustration and are not intended to limit the scope of the present invention.

The structure of the waste gas and liquid treatment and heat recovery device of the embodiment is shown in fig. 4, and comprises a combustion chamber, a turbulent flow chamber, a steady flow chamber and a heat recovery chamber which are sequentially communicated, and the internal structure of the device is shown in fig. 3, wherein

The combustion chamber is a cavity, two high-temperature nozzles and a combustion head are arranged on the cavity, waste gas and waste liquid can be conveyed to the high-temperature nozzles through an external pipeline to be sprayed into the combustion chamber, natural gas is conveyed to the combustion head through the external pipeline to be sprayed into the combustion chamber, the natural gas and the waste liquid are combusted together in the combustion chamber, the temperature of the combustion chamber is controlled to operate between 700 ℃ and 1200 ℃ according to the properties of different waste gas and waste liquid, and the temperature of the combustion chamber can be adjusted according to the flow of the natural gas.

The turbulent chamber is a cylindrical channel, two ends of the turbulent chamber are respectively communicated with the combustion chamber and the flow stabilizing chamber, the cross section area of the channel is smaller than that of the combustion chamber and the flow stabilizing chamber, so that a Venturi effect is formed, waste gas and waste liquid are initially combusted in the combustion chamber to be changed into a gas mixture with complex components, and the gas mixture is uniformly mixed under the turbulence action of the turbulent chamber and then enters the flow stabilizing chamber.

The steady flow chamber is a cavity, and the steady flow chamber mainly has the effect of ensuring that the high-temperature flue gas can have sufficient residence time so as to ensure the sufficiency of combustion.
