System for shortening starting time of imported gasifier technology

Abstract

The invention discloses a system for shortening the starting time of an imported gasification furnace technology, which is characterized in that the middle part of a gasification furnace is connected with a second pipeline, the second pipeline is connected with a carbon black separator, the carbon black separator is connected to the middle part of a washing tower through a third pipeline, the top end of the gasification furnace is connected with a first pipeline, and the first pipeline is connected with a stamping pipeline; the washing tower is connected with a fourth pipeline, the fourth pipeline is connected to the carbon black chilling pipe, the washing water pump is connected to the upper end of the washing tower through a fifth pipeline, the fifth pipeline is provided with a sixth pipeline, the sixth pipeline is connected to the lower end of the gasification furnace, and the spraying water pump b is connected to the carbon black chilling pipe. The carbon black chilling pipe is connected with a No.8 pipeline, the No.8 pipeline is connected to the gasification furnace, the No.8 pipeline is provided with a No.9 pipeline, the No.9 pipeline is connected to the ejector, and the ejector is connected to the chimney through a pipeline. The device is simple in structure, convenient and fast to operate, and capable of reducing fuel gas and air consumption and shortening the starting time of oil residue hydrogen production gasification.

Description

technical field [0001] The invention relates to a system, more specifically, to a system for shortening the start-up time of imported gasification furnace technology, which belongs to the field of petrochemical industry. Background technique [0002] If the Shell heavy oil gasifier fails to feed or the car jumps during the start-up process, the E200 logic system will automatically execute the GSD shutdown and prepare for the next stage as needed. Through the technical summary of the start-up stage, it is found that the design of the burner and the design of the refractory material can meet the requirements of continuous start-up. According to the Shell logic control and PID design, if there is a failure in feeding the gasifier or a jump occurs during the start-up process, the start-up will start again. stage, it takes 6-10 hours, the driving time is long, and the loss of fuel gas and air during the second driving period is high, so it is urgent to pass technical demonstratio...

Through the technical summary of the start-up stage, it is found that the design of the burner and the design of the refractory material can meet the requirements of continuous start-up. According to the Shell logic control and PID design, if there is a failure in feeding the gasifier or a jump occurs during the start-up process, the start-up will start again. stage, it takes 6-10 hours, the driving time is long, and the loss of fuel gas and air during the second driving period is high, so it is urgent to pass technical demonstration and technical improvement to realize the shortened time of jumping into the driving stage, which greatly improves the hot standby and The efficiency of the second start-up greatly reduces the loss of fuel gas and air during the second start-up is inevitable
