Novel fixed bed adsorption tower

Abstract

The invention discloses a novel fixed bed adsorption tower, which comprises a dedusting box and a support frame, and a motor box is fixedly installed on the right side of the dedusting box, a motor isfixedly installed in the motor box, the output shaft of the motor is fixedly connected with a lead screw, the surface of the lead screw is sleeved with a threaded sliding block, a brush is fixedly installed on the top of a fixing block, and a dust collection box is rotatably connected to the bottom of the dedusting box. An air inlet is used for air intake; an air outlet is used for discharging gas, the gas is fed into the dedusting box through a gas conveying pipe, the gas passes through a filter screen, dust in the gas adheres to the lower side of the filter screen, the filtered gas enters agas outlet pipe through the filter screen and is conveyed away, and therefore the dust filtering effect of the gas is achieved. The dust collection box is convenient to disassemble, assemble and clean. Then, the filter screen can be automatically cleaned without manual cleaning. Compared with the prior art, process steps are reduced, the structure is simple, the purification rate is high, and theservice life is long.

Description

technical field [0001] The invention relates to the technical field of coal gas dedusting and purification, in particular to a novel fixed-bed adsorption tower. Background technique [0002] Coal-to-gas refers to the process of injecting air, water vapor or hydrogen into coal or coal char to produce combustible gas under high temperature and high pressure conditions. It is an important way and means for clean utilization of coal resources. The application of coal gasification combined cycle power generation system has further promoted the development of coal gasification technology. However, the high-temperature gas produced by coal-to-gas contains a large amount of dust, which will not only reduce the quality of the gas, but also cause wear to the blades of the gas turbine, reducing the service life and working efficiency of the gas turbine. Therefore, it is necessary to dedust and purify the high-temperature gas produced from coal-to-gas. Usually wet purification process...

AI Technical Summary

Problems solved by technology

However, the outlet temperature of the produced gas at the gasifier can reach up to 800°C, and the commonly used bag filter and electrostatic precipitator are difficult to meet the requirements

Although there are also dry dust removal devices through filtration and purification in the prior art, these devices have defects such as numerous process steps, complex structures, poor sealing, low purification rate, short service life, and troublesome replacement of failed parts.
