Preparation method and device for rapidly-activated active coke

Abstract

The invention provides a preparation method and device for rapidly-activated active coke and particularly provides a preparation method of rapidly-activated active coke. The preparation method comprises the following steps of firstly, improving the existing rotary furnace for carbonization as follows: a, additionally arranging a steam pipeline in the furnace, namely necking a pipe head of a 310S stainless steel pipe with the pipe head of DN50 to DN15, inserting the stainless steel pipe from a combustion chamber at the head of the furnace to a discharging hole formed in the head of the furnace, and carrying out two-point support on the middle of the stainless steel pipe by using 310S angle iron; b, conveying combustible substances released by low-temperature carbonization of raw materials in a furnace body in the carbonization process from the tail to the head of the furnace through an underground flue by virtue of an injection pump so as to combust and furthermore increase the carbonization temperatures of the raw materials at the head of the furnace from 650 DEG C to 850 DEG C; and then, introducing steam from a waste heat boiler to the steam pipeline, conveying the steam to the discharging hole formed in the head of the furnace to carry out activating treatment on the raw materials for 15 minutes, and next, discharging. The invention provides a carbonization and activation integrated preparation technology for active coke, which is favorable in market application prospect.

Description

technical field [0001] The invention relates to a preparation method of active coke, in particular to a preparation method of rapidly activating active coke and a device thereof. Background technique [0002] At present, the global demand for desulfurization and denitrification active coke is increasing year by year, and a large number of industrial enterprise waste gas treatment projects arranged by the state during the "Twelfth Five-Year Plan" period have been launched, especially the dry power plant tail gas desulfurization technology arranged in the national "863" plan has been successful , has now entered the stage of demonstration and promotion, which will further stimulate the market demand for desulfurization and denitrification active coke. It is estimated that by the end of the "Twelfth Five-Year Plan", a demand scale of 100,000 tons of desulfurization and denitrification active coke will be formed. [0003] At present, one of the main problems restricting the prod...
