Tank-entering type coke quenching car

Abstract

The invention provides a tank-entering type coke quenching car which comprises a coke quenching tank car and a carrying flatcar, a track walking mechanism is arranged below a bearing main frame of thecarrying flatcar, and a connecting auxiliary frame capable of turning laterally is arranged above the bearing main frame of the carrying flatcar; the coke quenching tank car is arranged on the connecting auxiliary frame, a hinged door is arranged on one side of the coke quenching tank car, a crank arm connecting rod mechanism is arranged at the bottom and connected with a first door opening rotating shaft, and the first door opening rotating shaft is sleeved with a ratchet wheel door locking mechanism; the coke quenching tank car is provided with a rail roller, and a rollover hydraulic cylinder is arranged between the rail roller and the bearing main frame; the quenching tank car is provided with a transmission rack, and a transmission gear is arranged at the front end of the connecting auxiliary frame and connected with a hydraulic motor. A coke pushing trolley is arranged on the rear portion of the connecting auxiliary frame and connected with the coke quenching tank car through a buckling and hanging mechanism, and a second door opening rotating shaft is arranged at the bottom of the coke pushing trolley. The first door opening rotating shaft is detachably connected with the second door opening rotating shaft, and a gearbox door opening mechanism is arranged at the rear end of the bearing main frame. The coke quenching car recovers steam while quenching coke in a closed manner, has a self-discharging function and can discharge coke quickly.

Description

technical field [0001] The invention belongs to the field of coke quenching vehicles, in particular to a tank-entry type coke quenching vehicle. Background technique [0002] Coke is an important raw material in the iron and steel industry. The high-temperature coke (red coke) released from the coking chamber of the coke oven needs to be cooled rapidly in a short period of time, that is, coke quenching. The coke quenching car is a supporting equipment for large coke ovens. It generally runs on the track below the coke side of the coke oven. It is used to accept the coke at about 1000 °C exported by the coke guiding car and transport it to the coke quenching room for coke quenching. , and finally transport the extinguished coking coal to the designated place. Red coke contains a lot of heat energy, if it can be recycled, it can save energy and reduce emissions at the same time.

AI Technical Summary

Problems solved by technology

[0003] So far, coke quenching is mainly based on wet coke quenching in an open system, which is sprayed with water to cool down. This method has simple equipment and fast coke quenching speed, but it loses a lot of heat energy carried by red coke and causes environmental pollution.

In addition, CDQ technology, which uses nitrogen to cool red coke for power generation, has also been widely used in industrial practice, and has played a good role in recovering energy and reducing pollutant emissions. However, the equipment investment of nitrogen-cooled CDQ and operating costs are high, which brings a heavy cost burden to the business operation

[0004] In addition to traditional wet coke quenching and dry coke quenching, people have explored water spray coke quenching technology under airtight conditions in production practice, which has a good effect on reducing the investment cost of heat energy recovery and preventing pollution, but the equipment investment and operational stability On the other hand, it cannot meet the requirements of coke quenching operation in the coking industry
