The main characteristic technologies are as follows:
Coke oven asymmetric flue technology, single oven pressure control technology, coal moisture control technology, CDQ and waste heat power generation technology, etc.
Coke Oven Asymmetric Flue Technology:
By using the characteristics of fluid dynamics, the waste gas box and flue are arranged on the coke side of the coke oven, and the mixed gas and air inlet device is arranged on the pusher side of the coke oven, so that the gas flow and air flow of the heating flues from the pusher side to the coke side can be conveniently adjusted, the waste gas flow can be conveniently discharged, and the longwise heating uniformity of the coke oven is facilitated.
Single Oven Pressure Control Technology:
The coke oven adopts single oven pressure control system to realize smokeless coal charging. The single coking chamber pressure control can avoid the smoke and fire out of the coke oven and improve the environment, the functions of high-pressure ammonia water for smoke elimination and ground dedusting station can be replaced to reduce the investment and operation cost, and simultaneously reduce the emission of raw gas.
Coking Coal Moisture Control Technology:
SDM independently developed a new generation of patent technology of integrated coal moisture control and crushing, which mainly uses the hot flue gas to make the moisture of coal charged into the oven stable and controllable. This technology has the advantages of other coal moisture control technologies as well as the following unique advantages: simple and direct process flow, convenient operation, low operation and maintenance cost, and low comprehensive energy consumption
Small occupied area, especially suitable for the modification of existing production systems, basically no increase in production operation and maintenance personnel
Low investment, 60~70% of other processes under the same conditions
The system is safe and reliable, and has no
limit to the moisture content of the raw coal.
