Efficient catalytic cracking device for petrochemical industry production

Abstract

The invention discloses an efficient catalytic cracking device for petrochemical production, and relates to the technical field of petroleum catalytic cracking; the efficient catalytic cracking device comprises a catalytic cracking device, wherein the right side of the catalytic cracking device is fixedly provided with a side support, the top of the side support is fixedly provided with a waste gas treatment device, and four corners of the bottom of the catalytic cracking device are fixedly provided with supporting legs. Through ingenious design and combination of the hollow conveying ring, the main spraying agent head and the auxiliary spraying agent head, when crude oil is catalyzed, a booster pump on the top of a catalyst tank is used for pressurizing to convey an internal catalyst to the hollow conveying ring, and then the catalyst is conveyed to the main spraying agent head and the auxiliary spraying agent head at the bottoms of a stirring shaft and a stirring paddle through the hollow conveying ring; besides, by adopting the combined arrangement of the air filter element and the exhaust fan, waste gas can be conveyed to the air filter element in the waste gas treatment device through a pipeline connected to the top of the catalytic cracking device for comprehensive multi-layer filtration, wherein the exhaust fan plays a role in accelerating filtration in the process.

Description

technical field [0001] The invention relates to a catalytic cracking device, relates to the technical field of petroleum catalytic cracking, in particular to a high-efficiency catalytic cracking device for petrochemical production. Background technique [0002] Catalytic cracking is one of the petroleum refining processes. It is a process in which heavy oil undergoes a cracking reaction under the action of heat and a catalyst, and is converted into cracked gas, gasoline and diesel oil. Macromolecular hydrocarbons crack and condense under the action of heat. Synthetic aluminum silicate catalysts are used: one is amorphous aluminum silicate type and the other is zeolite type. Usually fixed bed catalytic cracking is used with low activity. It is one of the main methods of secondary processing of petroleum. Under the action of high temperature and catalyst, heavy oil undergoes cracking reaction and is transformed into cracked gas, gasoline and diesel oil. The main reactions ...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a high-efficiency catalytic cracking device for petrochemical production, one of the purposes of which is to have a hollow conveying ring, a main spray head and a secondary spray head, to solve the problems caused by not adding a catalyst or adding a catalyst The position of the method is wrong, resulting in a decrease in catalytic cracking efficiency, or an increase in the energy consumption of catalytic cracking and increased cost waste; another purpose is to have an air filter element and an exhaust fan to solve the problem of exhaust gas due to the low filtration efficiency of the exhaust gas treatment device. The problem that the internal circulation cannot be discharged to achieve the effect of efficient treatment of waste gas. Another purpose is to have an air monitor and a water quality monitor to facilitate real-time monitoring of the treatment quality of the waste gas after treatment. If the monitoring reaches the standard, it will be discharged normally. If the monitoring does not meet the standard, the exhaust port will be closed quickly to stop the discharge, which is conducive to stopping the discharge in time and protecting the atmospheric environment. In addition, by installing a water quality monitor inside the sewage treatment device, by setting the water quality monitor at the end of the sewage treatment , real-time monitoring of the treated sewage, when the water quality monitoring fails to meet the standards, the discharge will also be stopped, which is conducive to the protection of water resources, and solves the problem of improper treatment of air and water quality leading to substandard treatment, and then continues to discharge and pollutes the environment and cannot be stopped in time The problem
