Abstract
The invention discloses a gasification briquette production process, which includes mixing well, by weight, 90-100 parts of raw pulverized coal, 4-10 parts of lignite powder, 0.1-0.5 part of caustic soda flakes and 10-15 parts of water, retting the mixed materials for 18-24 hours, and feeding the retted materials into a briquette machine for making briquettes. The lignite powder and the acoustic soda flakes are added to materials of the gasification briquettes in production, a retting procedure is added to the production process, humic acid contained in the lignite powder is extracted from strong alkali by retting, sodium humate is generated and used as binder, and the obtained gasification briquettes are high in thermal stability, mechanical strength and gasification performance.
Description
Technical field
The invention belongs to the coal processing technique field, be specifically related to a kind of gasification briquette production technique.
Background technology
The producer of domestic production gasification briquette is numerous at present, and gasification briquette is mainly used in chemical fertilizer industry, is used for the gas furnace gasification and produces coal gas.Existing gasification briquette production technique requires height to the calorific value of raw material coal dust, and the smokeless powder coal of high-quality that requires to adopt calorific value＞27Mj/Kg is as raw materials for production, and sticker adopts the mineral binder bond of wilkinite and so on more.For there not being sufficient high-quality coal resource, but have the area of abundant relatively smokeless powder coal inferior, expectation can fully effectively utilize the lower smokelessly powder coal inferior of its calorific value.
But; If adopt smokeless powder coal inferior as the raw material of producing gasification briquette; Because powder coal spoil productive rate height inferior smokeless, poor plasticity, soft heat point are low, go into gas furnace after adopting existing gasification briquette production technique to produce and can cause not only that moulded coal poor heat stability, bad mechanical strength, freezing of a furnace are serious, gasification can not be carried out, and owing to the interpolation mineral binder bond; The moulded coal calorific value further reduces, and the gasification productive rate is lower.Therefore, existing gasification briquette production technique can't effectively be utilized the lower inferior smokeless powder coal of calorific value.
Summary of the invention
In view of this, the invention provides a kind of gasification briquette production technique, the gasification briquette Heat stability is good of production, physical strength are high, gasification performance is good, can effectively utilize the lower inferior smokeless powder coal of calorific value as raw materials for production.
Gasification briquette production technique of the present invention; With weight part is that 90 ~ 100 parts raw material coal dust, 4 ~ 10 parts brown coal powder, 0.1 ~ 0.5 part the water thorough mixing of sheet alkali and 10 ~ 15 parts are even; With the material stack retting 18 ~ 24h behind the mixing, then the material behind the stack retting is sent into molding coal machine and produce moulded coal again.
Further, said raw material coal dust is the smokeless powder coal between calorific value 22Mj/Kg ~ 23Mj/Kg, and its granularity is crushed to below the 3mm;
Further, produce the excellent moulded coal that the moulded coal that obtains is diameter 16 ~ 20mm, length 20 ~ 35mm.
Beneficial effect of the present invention is:
The present invention has added brown coal powder and sheet alkali in the raw material of producing gasification briquette; And in the process of preparation, increased the operation of stack retting; Make the highly basic extracting go out humic acids contained in the brown coal powder through stack retting; Generate Sodium salts humic acids as sticker, make the gasification briquette Heat stability is good, physical strength height, the gasification performance that obtain at last good.
Therefore; The present invention can adopt the lower inferior smokeless powder coal of calorific value as the raw material coal dust; Gasification briquette ultimate compression strength＞the 80Kg for preparing, thermostability＞70%, physical strength＞70%, calorific value＞23Mj/Kg, and obtain productive rate＞2.5Nm after getting into the gas furnace gasification
3/ Kg, calorific value＞5000Kj/Nm
3Producer gas, the type coal gasification productive rate is high, the gasification gas calorific value is stable, makes the smokeless powder coal of low-calorie poor quality obtain fully effectively utilizing.
