Device and method for transporting raw material powdered coal used for gasifier high-pressure bin and replacing plunger

Abstract

The invention discloses a device and method for transporting raw material powdered coal used for a gasifier high-pressure bin and replacing a plunger, and belongs to the field of raw material powderedcoal transporting and replacing devices and methods. The plunger of the replacing device is located in a plunger cylinder, one end of the plunger cylinder is connected with a plunger driving device,and a driving rod of the plunger driving device is connected with the plunger in the plunger cylinder; a fed powdered coal sealing valve is connected with the other end of the plunger cylinder, and the fed powdered coal sealing valve is connected with a raw material powdered coal feeding opening of the gasifier high-pressure bin; and a plunger cylinder feeding valve is connected with the portion,at one end of the feeding valve, on a plunger cylinder wall, and the plunger cylinder feeding valve is connected with a powdered coal transporting pipeline. The device for transporting the raw material powdered coal used for the gasifier high-pressure bin and replacing the plunger has the advantages that equipment is little, the equipment is simple in structure, and the device for transporting theraw material powdered coal used for the gasifier high-pressure bin and replacing the plunger is efficient, energy-saving and long in service life. The sealing effect is good, noise is little, the fault rate is low, energy consumption is low, and the space occupancy rate is low. System investment is reduced. The equipment integrity is high, installation and adjustment are easy, and maintenance issimple. The raw material powdered coal for the gasifier high-pressure bin is transported at high pressure in a sealed mode, the working efficiency is improved, and an energy saving effect is achieved.

Description

technical field [0001] The invention relates to a raw material pulverized coal conveying replacement device and method, in particular to a raw material pulverized coal conveying plunger replacement device and method for a high-pressure chamber of a gasification furnace. Background technique [0002] At present, the equipment used to provide pulverized coal raw materials for the high-pressure chamber of the gasifier is the lock bucket pressurized chamber, and the pulverized coal high-pressure conveying gas generation equipment, which uses high-pressure gas to push the raw pulverized coal in the lock bucket pressurized chamber to the gasifier. The high-pressure chamber provides pulverized coal raw materials, and the pulverized coal raw materials must be replaced with the pulverized coal high-pressure delivery gas of the same volume as the lock bucket pressurization chamber every time. If all the high-pressure gas inside is decompressed and released into the atmosphere, it need...
