An energy-saving activated carbon production converter

Abstract

The invention relates to an energy efficient converter for producing active carbon. The converter comprises a converter body; multiple gas inlet systems that are communicated with each other are evenly distributed on the lateral wall of the converter body; each gas inlet system comprises a steam distributing pipe and a plurality of steam pipes that are evenly distributed on the steam distributing pipe along the circumference; gas inlet pipes that are communicated with the lateral wall of the converter body are symmetrically arranged on each steam pipe; one end, which is close to a corresponding steam distributing pipe, of each steam pipe is provided with a control stop valve; each control stop valve comprises a butterfly valve that is movably connected to a cross shape handle and a stop block that is opposite to the handle, the stop blocks are movably connected to supports that are arranged on two sides of the converter body, the tail part of the converter body is connected to a waste heat boiler, the steam outlet in the top of the waste heat boiler is communicated with the gas inlet systems of the converter; the tail part of the waste heat boiler is communicated with a boiler draught fan; the top of the flue arranged in the air outlet of the boiler draught fan is provided with a bypass pipeline, the bypass pipeline is communicated with the gas inlet systems, and the tail part of the boiler draught fan is communicated with an external chimney.

Description

technical field [0001] The invention relates to an energy-saving activated carbon production converter. Background technique [0002] Activated carbon is a kind of carbon with huge surface area and adsorption capacity. At present, the equipment for producing activated carbon needs to be equipped with a boiler, and the steam generated by the boiler is used as the activator. However, if there is a boiler, it must be fired with coal or natural gas. The culprit of PM2.5, which increases the cost of production. In addition, in the existing converter, steam is continuously added during the rotating process of the converter, but in fact, all the air inlets are continuously added with steam. First, the amount of steam is not enough, and a lot of steam is wasted; Adding steam near the material can directly react with the charcoal surface, but adding steam to the far end of the furnace will lower the temperature in the furnace, slow down the reaction speed, and prolong the reaction t...

[0002] Activated carbon is a kind of carbon with huge surface area and adsorption capacity. At present, the equipment for producing activated carbon needs to be equipped with a boiler, and the steam generated by the boiler is used as the activator. However, if there is a boiler, coal or natural gas must be burned. The culprit of PM2.5, which increases the cost of production

In addition, the existing steam adding to the converter is to add steam continuously during the rotating process of the converter, but in fact, all the air inlets are continuously added with steam. First, the amount of steam is not enough and a lot of steam is wasted; Adding steam near the material can directly react with the charcoal surface, but adding steam to the far end of the furnace will lower the temperature in the furnace, slow down the reaction speed, and prolong the reaction time of the material in the furnace, so the length of the current converter is very long. Long, once shortened, the products produced are unqualified
