Non-stop ash discharge device for fixed bed clearance gas producer

Abstract

The present invention relates to a non-stop ash discharge device for a fixed bed clearance gas producer. The device has the following improvements: an original ash box is divided into an upper ash box and a lower ash box; a set of sealing device is added between the upper ash box and the lower ash box; an upper ash gate sealing assembly and a lower ash gate sealing assembly are controlled by hydraulic drive; a safety interlock is arranged on control oil-way of two ash gates to prevent security status caused by simultaneous opening of the two ash gates during ash discharge process; thereby realizing safe ash discharge of a gas-making furnace in continuous normal operation condition. The non-stop ash discharge device for a fixed bed clearance gas producer of the invention can be widely used in gas producing sections, adopting fixed bed clearance gasification gas production method and continuous oxygen enriched gas production method, in chemical fertilizer plant and chemical plant, and has good economic and social benefits.

Description

technical field [0001] The invention relates to an ash discharge device, in particular to a non-stop ash discharge device for a fixed-bed gap type gas generator. Background technique [0002] At present, most of the traditional fixed-bed interstitial gasifiers used by small and medium-sized chemical fertilizer plants in China adopt the mode of stopping the furnace and discharging ash, that is, there is an ash box with a volume of about 0.9m3 under each side of the gas generator. When the ash reaches a certain Capacity, when ash needs to be discharged, first choose to stop the furnace during the blowing stage, manually open the left and right bin doors for ash discharge, the ash will fall into the slag hopper, after the ash is unloaded, manually close the ash door, and then notify the operator When the program-controlled machine is turned on, the main operator should set the program-controlled machine to perform a secondary up-blowing safety program before switching to the no...

AI Technical Summary

Problems solved by technology

Ash discharge after shutdown has the following disadvantages: First, the continuous operation of the gas generator cannot be guaranteed for gas production; Take necessary safety measures to deal with, such as: the requirements for starting and stopping the furnace must be blowing and secondary blowing, lack of flexibility and the phenomenon of waiting for the furnace
