Problems solved by technology

It is characterized by simple process, low investment, and easy operation and maintenance. The disadvantages are: ①The sensible heat of red coke, which accounts for about 3035% of the heat consumption of the entire coking process, is not effectively utilized; ;④The steam generated by coke quenching contains pollution, corrosive media and dust, and the discharge into the atmosphere is not only environmental pollution, but also a waste of heat energy

Abstract

The invention discloses a low-moisture coke quenching and waste heat utilizing device. The low-moisture coke quenching and waste heat utilizing device comprises a coke quenching car, a coke quenching tower, a high-pressure water channel, a waste heat boiler, a steam heat accumulator, a condensing steam turbine, a generator and the like and is characterized in that the high-pressure water channel, the coke quenching tower, the waste heat boiler, the steam heat accumulator and the condensing steam turbine form a water circulation system. The low-moisture coke quenching and waste heat utilizing device respectively integrates low-moisture coke quenching, coke quenching stabilization and dry-method coke quenching, water for coke quenching is saved, the coke quenching effect is good, and atmospheric pollution and heat energy waste are reduced. The device is simple in structure, low in invest cost, convenient to transport, capable of continuously working and good in economical efficiency.

Description

technical field [0001] The invention belongs to the field of low-moisture coke quenching, in particular to a device for low-moisture coke quenching and waste heat utilization. Background technique [0002] At present, there are two coke quenching methods for coke ovens at home and abroad: dry coke quenching and wet coke quenching. Dry coke quenching is a coke quenching method that cools red coke with low-temperature inert gas. Dry coke quenching is superior to wet coke quenching in terms of energy saving and coke quality improvement, but it occupies a large area, complex equipment structure, difficult manufacturing, high maintenance costs and large investment. Wet coke quenching is to spray red coke with water, including low-moisture coke quenching, stable coke quenching, etc., to reduce the red coke to below 100 degrees, and the steam generated is directly discharged into the atmosphere. It is characterized by simple process, low investment, and easy operation and mainten...
