Abstract

The invention discloses an environment-friendly and energy-saving coking device and a working method thereof. The environment-friendly and energy-saving coking device comprises a coke furnace, an electrical tar precipitator, a tar and ammonia water clarifying tank and a power plant, wherein a drying section, a dry distilling section and a coke quenching section are sequentially arranged inside thecoke furnace from top to bottom; a control valve for controlling one-way flowing of a gas flow and a material is arranged between every two adjacent sections. The environment-friendly and energy-saving coking device is good in sealing performance, simple, convenient to operate and convenient to observe, reduces pollution to the outside to the minimal extent, and is low in equipment cost; througharrangement of a waste gas recycling device on the drying section, the problem of environmental pollution caused by direct discharge of gas released from the drying section of the current coke furnaceis solved, so that the environment friendliness of the environment-friendly and energy-saving coking device is improved; in addition, in the scheme, the ground floating roof-type tar and ammonia water clarifying tank is provided and the tar and ammonia water clarifying tank is arranged on the ground, so that the problems that 90% of the current tar and ammonia water clarifying tanks commonly built underground have leakage problems and the leakage checking difficulty is large are solved; the tar and ammonia water clarifying tank on the ground is reasonable in structural design, and leakage checking and maintenance thereof are easy.
