Problems solved by technology

However, the chemical activation method has three major disadvantages: ①It is very corrosive to the equipment; ②It pollutes the environment; ③There are chemical activators in the activated carbon, so the application is limited
If crushing and granulation is used, the cost of activated carbon will be increased, which is uneconomical

Abstract

A system for producing activated carbon from straw, including a fried activated carbon furnace, a straw feeding system and a flue gas air activator delivery system. The straw feeding system includes a straw drying room, and a drying induced draft fan is installed at the discharge end , the feeding end is equipped with a broken straw screw propeller and a flue gas inlet pipe connected to the flue gas main pipe of the frying-type activated carbon furnace, and the discharge pipe provides dried straw for the frying-type activated carbon furnace through the cyclone dust collector; The above-mentioned flue gas air activator delivery system transports part of the flue gas discharged from the frying activated carbon furnace and the superheated steam generated by the system to the material frying and mixing chamber in the furnace section through the flue gas compressor. The production process is simplified and purified, the energy consumption is greatly reduced, and the product yield and product quality are improved.

Description

technical field [0001] The invention relates to an activated carbon production technology, in particular to a system for producing activated carbon by utilizing straw. Background technique [0002] At present, in terms of activated carbon production technology, it is common to use chemical activation to pretreat raw materials. The most representative chemical activation method pretreatments are: zinc chloride method, phosphoric acid (salt) method, calcium chloride method and chemical activation method with alkali as activator (alkali method). The chemical activation method is a method in which chemicals are added to raw materials, and then heated in an inert gas medium for carbonization and activation. However, the chemical activation method has three major disadvantages: ①It is very corrosive to the equipment; ②It pollutes the environment; ③There are chemical activators in the activated carbon, and its application is limited. [0003] The world-renowned activated carbon a...
