Problems solved by technology
For the up-suction gasifier, the structural form or method of ash discharge is generally adopted on the lower side of the furnace bottom. The ashes in the furnace are taken out from the ash outlet, which can solve the problem of ash discharge, but part of the carbonized and semi-carbonized materials in the furnace will also be discharged (taken out) together, and the ash cannot be cleaned or the ash Cleaning is inconvenient

The invention discloses an auger ash removing device of a gasification furnace. Air inlet pipes are arranged at the bottom end of an inner cavity of a furnace body, more than one air nozzle capable of being uniformly distributed or non-uniformly distributed is formed in each air inlet pipe, an ash discharging frame fixedly connected with an ash discharging hole is arranged at a bottom plate of the furnace body, the edge of an ash feeding hole in the upper end of an ash storage box is connected with the ash discharging frame, an outlet in the bottom end of the ash storage box is connected with an inlet of an auger sleeve, an auger is arranged in the auger sleeve, and an ash discharging hole is formed in the lower part of the ash discharging end of the auger sleeve. The auger ash removing device disclosed by the invention is convenient to operate, saves the operating time, is capable of realizing the continuous operation so that the ash cleaning quality is ensured, and has a practical value.
Description
[0001] technical field [0002] The invention relates to a gasification furnace auger ash removal device used in conjunction with an upward suction type gasification furnace. Background technique [0003] The ash cleaning of the gasifier is one of the key factors for the continuous use of the gasifier and the stability of the furnace condition. If the ash cleaning is not clean, it will affect the normal use of the gasifier. The gasification gas quality is not good, and the biomass is serious. The fuel is not gasified at all, and becomes burned as biomass fuel. For the up-suction gasifier, the structural form or method of ash discharge is generally adopted on the lower side of the furnace bottom. The ashes in the furnace are taken out from the ash outlet, which can solve the problem of ash discharge, but part of the carbonized and semi-carbonized materials in the furnace will also be discharged (taken out) together, and the ash cannot be cleaned or the ash Cleaning is inco...
