Abstract

The invention relates to a carbon electric roaster tail gas waste heat utilization device which comprises electric roasters, chimneys arranged at the tops of the electric roasters and a gas conveying pipeline. A blow-off valve is arranged at one end of the gas conveying pipeline, and a dust remover, a steam trap, a gas booster fan and a combustor are arranged at the other end of the gas conveying pipeline in sequence. The dust remover, the stream trap, the gas booster fan and the combustor are communicated through the gas conveying pipeline. Electric switch valves for opening and closing the chimneys are arranged in the middles of the chimneys. Tee pipes for guiding tail gas into the gas conveying pipeline are arranged at the positions, on the lower portions of the electric switch valves, of the chimneys, and inlets of the gas of the corresponding electric roasters in the gas conveying pipeline are formed in a gas conveying pipeline segment between the blow-off valve and the dust remover. Utilization of electric roaster tail gas waste heat is achieved, air can be purified, and haze weather is avoided.

Description

technical field [0001] The invention relates to a tail gas waste heat utilization device in the field of environmental protection, in particular to a carbon electric calciner tail gas waste heat utilization device. Background technique [0002] In the carbon industry, the electric calciner is a device for removing the volatile matter in the coal block. It heats the coal block through electrodes to dry out the volatile matter in the coal block. The carbonization process is carried out in an anaerobic environment. The carbonized coal is used as carbon material, and a part of the gas containing combustibles is discharged from the chimney of the electric calciner. After being ignited, the smoke is emitted into the atmosphere. This emptying method not only wastes energy but also pollutes the air. [0003] If it is possible to develop a waste heat utilization device for the tail gas of the electric calciner, the device can use the tail gas of the electric calciner, for example, t...
