Environment-friendly and energy-saving coking device and working method thereof

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.

Description

technical field [0001] The device of the invention belongs to the field of energy and chemical industry, and in particular relates to an environment-friendly and energy-saving coking device and a working method thereof. Background technique [0002] CDQ is one of the technologies that are currently encouraged by the state. It belongs to the items listed in the clean production technology guidance catalog recommended by the former State Economic and Trade Commission. It is in line with the relevant national industrial policies. It is a project to improve the environment, improve the quality of coke, and save resources. advanced technology. Dry coke quenching is in line with the basic national policy of environmental protection, can improve the utilization rate of resources and energy, and reduce environmental pollution. [0003] CDQ technology originated in Switzerland in the last century. Since then, the former Soviet Union, Japan, and Germany have successively made improve...

AI Technical Summary

Problems solved by technology

However, at present, the coke oven quenching method of semi-coke processing enterprises is basically the traditional wet coke quenching method. (1) The problem of wet coke quenching: it not only causes a great waste of energy, reduces the quality of semi-coke, but also seriously pollutes the environment

(2) Problems in dry coke quenching: coke dry quenching technology is a mature technology in the coking industry. It has been widely used in large and medium-sized coking enterprises at home and abroad, but it occupies a large area, complex equipment structure, and difficult to manufacture. Large, high maintenance cost, large investment, and serious coke burning loss

For independent coking enterprises, the absorbed heat generation is not easy to balance
