Comprehensive recycling power generating system applicable to purifying dust, dust-removing dust and semi-coke powder

Abstract

The invention relates to the technical field of dust recycling systems, in particular to a comprehensive recycling power generating system applicable to purifying dust, dust-removing dust and semi-coke powder. The system comprises a proportioning system body, a combusting system body, an excessive heat power generating system body and a waste gas treatment system body, the proportioning system body mixes the dust-removing dust, the purifying dust and the semi-coke powder according to a ratio to prepare particles of which the particle diameter is smaller than 3 mm, and the particles are delivered to the combusting system; the combusting system fully combusts the particles and generates overheated steam and waste gas, the overheated steam is delivered to the excessive heat power generating system to generate power, and the waste gas is delivered to the waste gas treatment system to be subjected to waste gas treatment and is then exhausted to atmosphere. The dust-removing dust and purifying dust in the producing process of a calcium carbide plant are systematically recycled, the problems of environment pollution, land occupancy and the like are solved, to serve as the basis of boilercombustion utilization, excessive heat is used for generating electricity, the electricity purchase cost is lowered, the market competitiveness is improved, the social benefit and environmental benefit are increased, the waste gas treatment system treats the waste gas, and the pollution is lowered.

Description

technical field [0001] The invention relates to the technical field of dust recovery and utilization systems, in particular to a power generation system suitable for recovery and comprehensive utilization of purified ash, dedusted ash and blue charcoal powder. Background technique [0002] As a high-pollution and high-energy-consuming industry, calcium carbide production is currently developing on a huge scale in my country. Under the global climate of energy conservation and emission reduction, on the one hand, my country is one of the world's largest producers of calcium carbide, and on the other hand, the task of energy conservation and consumption reduction in my country's calcium carbide production is arduous. [0003] The amount of purified ash and dedusting ash in the production of calcium carbide is very large, of which: 50-70kg of dedusting ash and 45kg of purified ash are produced per 1 ton of calcium carbide, but they are powdery and easy to fly, so they cannot be...

AI Technical Summary

Problems solved by technology

[0005] Semicoke powder is a mixture of finer particles and small particles produced in the production process of semicoke, which cannot be directly burned and comprehensively utilized, and the utilization rate is low. In the process of pushing and landfilling, it takes up a lot of land and pollutes the environment.
