Casting type coke carbonizing furnace

Abstract

A casting type coke carbonization furnace, including a carbonization furnace group, an operation platform, a coke quenching pool, a temperature control system, and a smoke detection system. The carbonization furnace group is composed of one or more single-hole furnaces, and each single-hole furnace consists of a furnace body , carbonization chamber, combustion chamber, air distribution device and flue; inside the shell of the furnace body, there is a ladder-shaped vertically high front and low rear, and a double-layer vault with a 180-degree semicircle in the horizontal direction. The carbonization under the vault The chamber has an inclined structure with a high front and a low rear; under the carbonization chamber is the combustion chamber, which has a 20-50 degree inclined plane bottom with a high front and a low rear, and the upper end of the combustion chamber has a feeding furnace door connected to the feeding platform , the lower end has a discharge furnace door connected to the coke quenching pool; there are 2-6 vertical flues and branch flues in the furnace body, a carbonization chamber distribution outlet is provided at the front and rear ends of the carbonization chamber, and the front and rear ends of the furnace body are Each is provided with two flue air distribution outlets; the invention provides comprehensive and uniform heating, fully burns fuel, efficiently utilizes heat energy, has fast heating speed, high heating temperature, reduces carbonization and coking time, improves production efficiency, prolongs service life, and reduces production costs .

Description

technical field [0001] The invention relates to metallurgical coking equipment, in particular to a casting type coking furnace. Background technique [0002] At present, most of the coke ovens used in my country's coking industry are 58-II or 80 types modified on the basis of 58-type ovens. The reheating coke oven has an air regenerator and a gas regenerator in the lower part of each carbonization chamber. In a combustion chamber, a pair of adjacent fire passages and four connected regenerators form a corresponding heating unit. This kind of coke oven basically uses main coking coal plus coal blending for coking. The disadvantage is that the coking coal reserves are small and the price is high, which cannot meet the increasing demand for coking. [0003] Because it is mainly coking coal, the volatile content of the raw material is about 30%, and 15% of the volatile content needs to be recovered by chemical production. Therefore, a lot of recovery equipment is required, and t...

Problems solved by technology

This kind of coke oven basically uses main coking coal plus coal blending for coking. The disadvantage is that the coking coal reserves are small and the price is high, which cannot meet the increasing demand for coking.

[0003] Because it is mainly coking coal, the volatile content of the raw material is about 30%, and 15% of the volatile content needs to be recovered by chemical production. Therefore, a lot of recovery equipment is required, and the investment is large, and in the recovery process, cyanide and other substances are recovered. , causing a lot of pollution, air pollution, not conducive to environmental protection

[0004] This kind of coke oven requires huge mechanical equipment such as coal loading trucks, horizontal smelting (or tamping) devices, coke pushing trucks, and coke pushing trucks when entering and discharging materials. The working environment is poor, and it is difficult to realize mechanization and automation of operations.
