Problems solved by technology

my country's current gasification briquettes are all briquettes for fixed-bed atmospheric coal gasifiers, and there is no briquette for fixed-bed pressurized coal gasifiers; and the raw coal used is all anthracite, which has not been compared with market prices. Low bituminous coal is used as briquette raw material to produce briquette for fixed bed pressurized coal gasifier

Embodiment 1

[0015] The components and weight percentages of the industrial briquette are: bituminous coal 62%, coking coal 15%, clay 10%, and sodium humate 13%.

[0016] Bituminous coal of 9.3 tons / hour rationed by the raw coal quantitative feeder 7 is transported by the belt, and the iron is removed by the raw coal iron remover 8, and then sent to the raw coal crusher 6, crushed to the pulverized coal below 3mm, and transported to the mixer B15 by the belt ; 1.5 tons / hour of clay is sent out by clay quantitative feeder 5, and sent to the crushed pulverized coal belt through belt; 2.25 tons / hour of coking coal is sent out by coking coal quantitative feeder 4, conveyed by belt, and passed through coking coal iron remover 3. After removing the iron, it is sent to the coking coal crusher 2 for crushing, and the crushed coking coal is conveyed to the crushed pulverized coal belt with a belt; after the sodium humate is prepared into a sodium humate solution in the sodium humate reactor 9, it is...

Embodiment 2

[0018] The components and weight percentages of the industrial briquette are: bituminous coal 72%, coking coal 10%, clay 8%, and sodium humate 10%.

[0019] Bituminous coal of 10.8 tons / hour rationed by the raw coal dosing feeder 7 is transported by the belt, and the iron is removed by the raw coal iron remover 8, and then sent to the raw coal crusher 6, crushed to the pulverized coal below 3mm, and transported to the mixer B 15 by the belt 1.2 tons / hour of clay is sent out by clay quantitative feeder 5, and sent to the crushed pulverized coal belt through belt; 1.5 tons / hour of coking coal is sent out by coking coal quantitative feeder 4, conveyed by belt, removed by coking coal After the iron is removed from the iron device 3, it is sent to the coking coal crusher 2 for crushing, and the crushed coking coal is conveyed to the crushed pulverized coal belt with a belt; after the sodium humate is prepared into a sodium humate solution in the sodium humate reactor 9, it is contro...

Embodiment 3

[0021] The components and weight percentages of the industrial briquette are: bituminous coal 82%, coking coal 7%, clay 5%, and sodium humate 6%.

[0022] Bituminous coal of 12.3 tons / hour rationed by the raw coal quantitative feeder 7 is transported by belt, and iron is removed by the raw coal iron remover 8, and then sent to the raw coal crusher 6, crushed to the pulverized coal below 3mm, and transported to the mixer B 15 by the belt Inside; 0.75 t / h of clay is sent out through clay dosing feeder 5 and sent to the crushed pulverized coal belt through belt; 1.05 t / h coking coal is sent out through coking coal dosing feeder 4, conveyed through belt, removed by coking coal After the iron is removed from the iron device 3, it is sent to the coking coal crusher 2 for crushing, and the crushed coking coal is conveyed to the crushed pulverized coal belt with a belt; after the sodium humate is prepared into a sodium humate solution in the sodium humate reactor 9, it is controlled by...

Abstract

The invention discloses an industrial molded coal and a manufacture process thereof, which uses soft coal with high moisture and high volatilization as raw material, coking coal, sodium humic acid and clay as caking agents. The method comprises the following steps: iron is removed from the raw material soft coal, and the raw material soft coal is crushed with the crushed particle less than or equal to 3mm; solid caking agents clay and coking coal are added to the crushed soft coal, and the liquid caking agent sodium humic acid is added to the crushed soft coal to be stirred and mixed; a storage stack is retted for aging for more than 24 hours; the aged coal is subjected to a secondary stirring; the aged coal is shaped at the pressure 10-30MPa; and the shaped coal is dried at a temperature lower than 90 DEG C to manufacture the molded coal. The industrial molded coal can be used for a fixed layer pressure coal gasification furnace.

Description

technical field [0001] The invention relates to a briquette, in particular to an industrial briquette and a production process thereof. Background technique [0002] At present, with the rapid development of society and economy, the amount of lump coal is increasing. With the increasing mechanized mining of coal, the output of natural lump coal has dropped sharply, the contradiction between supply and demand of lump coal has become increasingly prominent, and the price has been rising day by day. The price difference between quality blended coal (unscreened raw coal) and lump coal is more than 100 yuan. my country's existing large-scale coal gasification technologies include: Shell coal gasification technology, coal-water slurry gasification technology and fixed-bed pressurized coal gasification technology. Because the fixed bed pressurized coal gasification must use lump coal as the raw material, which restricts the application of the fixed bed pressurized coal gasificatio...
