Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of decoking equipment, especially relates to a coke tower decoking device. BACKGROUND

[0002] The delay coking pilot test device is mainly used for studying the delay coking process of heavy oil, adjusting device parameters, optimizing the product distribution of coke and generated oil gas, determining the optimal process conditions of the delay coking reaction process, and realizing efficient utilization of heavy oil resources. The raw oil is heated to about 500 DEG C by a heating furnace and then enters a coke tower for cracking reaction. Coke is generated in the coke reaction tower. After one reaction cycle, the coke generated in the coke tower needs to be removed. At present, the coke tower is generally decoked by hydraulic decoking. The hydraulic decoking has high automation degree, short decoking time, saves labor and steel, and is suitable for large-scale industrial production devices. However, the hydraulic decoking produces a large amount of wastewater, which needs to be treated to meet environmental protection requirements, and dry equipment needs to be added, increasing investment. The delay coking test device for scientific research and development has a small processing capacity, and the structure size of the coke tower is not suitable for the hydraulic decoking method. Therefore, manual decoking is usually adopted, which is difficult and time-consuming and labor-intensive.

[0003] Chinese patent CN215667826U discloses a decoking device for a coke tower, which comprises a heavy pipe wrench, a rock drill, a beam-type pulley, a support column and a support frame. The heavy pipe wrench is arranged on the left half of the support column, the beam-type pulley is arranged on the right half of the support column and can move left and right on the support column, the rock drill is arranged on the beam-type pulley and can move with the movement of the beam-type pulley, and the support frame is used for supporting the support column. The device further comprises a plurality of rock drill rods with different lengths and a plurality of drill bits with different models. The decoking device for the coke tower avoids environmental pollution caused by hydraulic decoking and reduces the influence on the water content and measurement of needle coke. In the device, the coke tower and the rock drill are fixed on the support, the position of the rock drill is controlled by a winch, a cable and a pulley, and different drill bits are replaced to remove needle coke at different positions.

[0004] The above-mentioned patent uses a winch, a cable and a pulley to control the position of the rock drill, and different drill bits are replaced to remove needle coke at different positions. The coke tower is relatively clean after decoking, but the drill bits need to be replaced many times during use, the coke in the coke tower is cleaned and loaded into a bag, and the decoking process is relatively complicated.
