Improved shell charcoal activation furnace

Abstract

The invention discloses an improved shell charcoal activation furnace, which comprises a feeding channel, flues and a steam supply system, wherein the feeding channel and the flues are arranged in a staggering way, the feeding channel comprises a feeding port, a carbonization section, an activation section and a discharge port which are arranged from top to bottom, the flues are arranged into a plurality of layers, all the layers are communicated with one another end to end to form a circulation flue, and smoke vents are arranged between the feeding channel and the flues. The improved shell charcoal activation furnace is characterized in that: reinforcing ribs are laterally and horizontally arranged in the feeding channel uniformly, are laterally and horizontally arranged equidistantly, and are aligned from top to bottom to form a latticed feeding channel, the smoke vents between the feeding channel and the flues are inclined holes, and a smoke inlet which is communicated with the feeding channel is positioned at a lower position. Because the reinforcing ribs are arranged in the feeding channel, the strength of the feeding channel is increased, the feeding channel is ensured to not deform, meanwhile, the reinforcing ribs have the function of naturally turning the charcoal, the charcoal activation effect is further improved, the product quality is more stable, the smoke vents between the feeding channel and the flues are the inclined holes, so smoke is more smoothly discharged.

Description

Technical field: [0001] The invention relates to a kind of activated carbon production equipment, in particular to an improved fruit shell activated carbon activation furnace. Background technique: [0002] Activated carbon is an important material in various industries and environmental protection industries, and the market demand is increasing day by day, especially the fruit shell activated carbon is more in demand. The main process of producing activated carbon from shells is to carbonize and activate the raw materials at a certain temperature to make them reach the specified physical and chemical indicators. At present, the kiln-type activation furnace made of refractory materials is composed of a forehearth, a flue and a steam supply system. The forehearth and the flue are arranged in a staggered manner. section, activation section, outlet, and the flue is divided into several layers, each layer is connected end to end to form a circulating flue, and there is a smoke ...

Problems solved by technology

At present, the kiln-type activation furnace made of refractory materials is composed of a forehearth, a flue and a steam supply system. The forehearth and the flue are arranged in a staggered manner. section, activation section, outlet, and the flue is divided into several layers, each layer is connected end to end to form a circulating flue, and there is a smoke exhaust hole between the material path and the flue. There are the following problems in the type activation furnace. First, the material channel is an unobstructed passage from top to bottom, and the carbon material does not turn during the falling process. This has a great impact on the carbonization and activation effect of the carbon material, resulting in the quality of the product It is not easy to guarantee; the second is that the smoke exhaust holes between the forehearth and the flue are mostly set horizontally, which is not conducive to the smooth discharge of the smoke in the forehearth into the flue, and the phenomenon that the smoke exhaust holes are often blocked by carbon materials, resulting in exhaust The smoke is not smooth, which affects the product quality; the third is that the forehearth is a barrier-free passage from top to bottom, and its strength is lacking. When the pressure increases due to poor smoke exhaust in the flue, the forehearth will be deformed and affect the whereabouts of the charcoal.
