Petrochemical oil refining and coking equipment

Abstract

The invention discloses petrochemical oil refining and coking equipment. The equipment structurally comprises a slag removal pipe machine body, a bottom cover machine, a connecting groove frame, a coking furnace, a top cover machine, a connecting pipe and a tail gas absorption tower, and the connecting groove frame is installed below the bottom cover machine and connected with the bottom cover machine in a locked mode. When the equipment is used, by arranging the slag removal pipe machine body, the situation that gas which is subjected to coking treatment of the coke tower and is directly transferred upwards contains a part of coke slag, the coke slag is continuously attached to the inner wall of the transfer pipe in the transfer process, and due to the particularity of the position, the coke slag is inconvenient to clean, finally an internal pipeline of the tail gas absorption tower is easily blocked, operating burden is brought to subsequent exhaust gas treatment facilities or damage is caused to the facilitiescan be avoided. I the coking process of an equipment coke tower, gas generated by the equipment coke tower passes through the pretreatment pipe along the connecting pipe, then coke is attached to the inner wall of the pretreatment pipe firstly, slag scraping piece devices are matched with one another, and coke residue components in the inner pipeline can be effectively scraped off and are uniformly collected under the mutual cooperation of the residue collecting cylinders, so that the influence of the coke residue components on subsequent procedures is reduced.

Description

technical field [0001] The invention relates to petrochemical refinery coking equipment, which belongs to the field of refinery equipment. Background technique [0002] my country is a country with a complex energy structure, but at present, the consumption of coal and petroleum products has always occupied an important position in my country's energy structure. Coking generally refers to the process of carbonization and zooming of organic matter. In coal carbonization, it refers to high-temperature carbonization. In petroleum processing, coking is the abbreviation of petroleum coking, which refers to the process of deep cracking and condensation reaction of heavy oil at a high temperature of about 500 degrees to produce gas, gasoline, diesel oil, wax oil and petroleum coke. Coking mainly includes five processes including delayed coking, kettle coking, open hearth coking and flexible coking. [0003] The existing technology has the following disadvantages: after the coking tr...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a petrochemical refinery coking equipment to solve the problem that the gas that passes through the coke tower directly contains a part of coke slag during the coking process. The slag will continue to adhere to the inner wall of the transfer pipe. Due to the special location, it is inconvenient to clean up, and eventually it is easy to block the internal pipe of the exhaust gas absorption tower, which will bring operational burden or damage to the subsequent exhaust gas treatment facilities.
