Horizontal type moving bed particle layer filtration high-temperature oil gas dedusting technology and device

Abstract

The invention discloses a horizontal type moving bed particle layer filtration high-temperature oil gas dedusting technology and device. The device comprises a shell, a material filtering bin and a plurality of gas inlet pipes are arranged on the upper portion of the shell, and distributing pipes are arranged in the gas inlet pipes. A hot semicoke inlet is formed in the upper end of the material filtering bin. Feeding rollers are arranged in the material filtering bin, and a feeding gate plate is vertically mounted at the front end tangent line position in the rotating direction of the feeding rollers. A bar grating type screener is obliquely mounted below the feeding rollers. A tooth rake device with the top being provided with a rotating shaft is mounted below the bar grating type screener. A driving wheel and a driven wheel are arranged in the shell, a conveying belt is arranged between the driving wheel and the driven wheel, and cold purification high-temperature oil gas outlets are formed below the conveying belt. A material stopping tube and a sealing roller which is tangent to the material stopping tube are arranged beside the driving wheel. A shell segregation board is arranged between the axis of the driving wheel and the axis of the sealing roller. A particle filtering layer is formed on the conveying belt. High-dust semicoke discharging outlets are formed below the shell. The technology and device overcome the defects that the particle layer of an existing fixed bed particle layer filtration high-temperature oil gas dedusting device is backwashed and is difficult to regenerate, and the operating period is short.

Description

technical field [0001] The invention belongs to the field of coal (oil shale) pyrolysis, and in particular relates to a process and a device for filtering high-temperature oil and gas and dedusting with a horizontal moving bed granular layer. Background technique [0002] my country is relatively rich in coal resources, but poor in oil and natural gas resources. With the continuous enhancement of my country's economic strength and the continuous improvement of people's living standards, the consumption of petroleum products has been increasing year by year. In order to alleviate the increasing shortage of petroleum products, fully benefit its own abundant coal resources, and realize the polygeneration of coal, oil, electricity and gas, it is an important way for the efficient and low-pollution comprehensive utilization of coal resources in the future. Pulverized coal pyrolysis technology is one of the core technologies for realizing polygeneration of coal, and is the key to...
