Abstract
The present invention relates to a briquette for gasification, which uses Jingxi smokeless dust coal as a raw material. A composite binding agent composed of coal slack and a small amount of calcium lignosulfonate is added. As the coal slack extracted by a coal mine is used as a main constituent of the composite binding agent in the briquette, the briquette for gasification is not only favorable to waste utilization, but also reduces the briquette cost. The cold/heat intensity of the briquette is high and the thermal stability is good, so the briquette is superior to Jingxi block coal when the briquette is used for the gasification.
Description
The present invention relates to a kind of moulded coal, in particularly being suitable for, the formed coal for gasification that small-sized synthesis ammonia plant uses.
At present, the chemical fertilizers production of China is to be main raw material with the coal.A large amount of medium and small synthetic ammonia factory fixed bed water-gas generators are produced synthetic raw gas, and this vapourizing furnace need be used anthracite block coal, and along with the increase year by year of fertilizer production, lump coal supply day is becoming tight.Therefore, development anthracite fine coal forming technique increases moulded coal output and has become very urgent vital task.At present, the carbonating briquette production technology of widely using at synthesis ammonia plant need add 20～30% lime in feed coal, cause ash content to increase.And this moulding process also needs to carry out long carbonating to moulded coal and handles, and makes the complete processing complexity, and cost raises.Therefore, need a kind of binding agent expense of exploitation low, the simple coal powder formation technology of complete processing.Mining area, Jingxi district is anthracitic important producing region.Beijing Coal Mining Administration produces surplus the raw coal 600 ten thousand tons per year, and wherein fine coal mainly is to make domestic fuel more than 3,000,000 tons, and lump coal is because poor heat stability, and minute quantity is used for chemical fertilizers production.The anthracite block coal that near Beijing fertilizer plant uses the other places to ship in a large number, this has not only increased the cost of chemical fertilizers production, causes the anxiety of lump coal supply simultaneously.
The objective of the invention is to utilize Jingxi district anthracite fine coal to produce a kind of formed coal for gasification of inexpensive easy popularization,, provide a new technological approaches for enlarging of the application of Jingxi district fine coal in chemical fertilizers production.
For achieving the above object, the present invention adopts following scheme, and moulded coal is a raw material with Jingxi district anthracite fine coal, adds compound binding agent (Jingxi district coal gangue and calcium lignin sulphonate) and makes.
If the consumption of binding agent is very little in the moulded coal, its ultimate compression strength is not high enough, though consumption many intensity increase, ash content increases more, uneconomical again.General consumption is coal gangue 5～9%, calcium lignin sulphonate 0.3～1.5 (weight percentage).Optimum amount: coal gangue 5～7%, calcium lignin sulphonate are 0.5～0.7%.
The preparation method of moulded coal comprises:
1, feed coal is crushed to below 3 millimeters.
2, with binding agent blending in proportion, add water, stir, the compound before the moulding
Water ratio is 9～12%.
3, send twin rollers coldmoulding, forming pressure is 250～400kg/cm
2
4, drying.
The invention will be further described below in conjunction with embodiment:
The analytical results of feed coal and coal gangue is listed in the table below:
| Sample | Moisture content Nad | Ash Aad | Fugitive constituent Vad | Ash fusion point ℃ | ||
| DT | ST | FT | ||||
| Big breeze coal of Wang Ping village breeze coal Wang Ping village pit coal spoil | 2.48 2.87 1.74 | 20.34 24.96 90.74 | 4.15 4.73 5.26 | 1430 1130 1330 | ＞1500 1230 ＞1500 | 1270 |
Embodiment 1: the proportioning of moulded coal is: 92.3 parts in Jingxi district Da Tai breeze coal, and 7 parts of Wang Ping village pit coal spoils, 0.7 part of calcium lignin sulphonate is after 9-10% adds the water even blend, to send into the shaper extrusion forming by the compound total water content, forming pressure is 300kg/cm
2, the wet bulb of extrusion under 60～70 ℃ of temperature dry 2 hours, under 100～120 ℃ of temperature dry 2～3 hours again.After measured, the cold ultimate compression strength of moulded coal is the 57.6kg/ ball, and hot compressive strength is the 31kg/ ball, and ash fusion point ST is 1280 ℃.
Embodiment 2: 92.5 parts in Jingxi district Wang Pingcun breeze coal, and 7 parts of coal gangues, 0.5 part of calcium lignin sulphonate, complete processing is with embodiment 1.The cold ultimate compression strength of moulded coal is the 67kg/ ball, and hot compressive strength is the 32kg/ ball.
Embodiment 3: 94.5 parts in Jingxi district Da Tai breeze coal, and 5 parts of coal gangues, 0.5 part of calcium lignin sulphonate, complete processing is with example 1.The cold ultimate compression strength of moulded coal is the 46kg/ ball, and hot strength is the 30kg/ ball, and ash fusion point ST is 1260 ℃.
Advantage of the present invention is: the hot and cold intensity of moulded coal is high, and heat endurance is better than Jingxi district lump coal. Because the waste residue of selecting the colliery to discharge---the calcium lignosulfonate of a large amount of supplies is made binding agent on gangue and the market, has reduced the production cost of moulded coal, and the expense of the binding agent that moulded coal per ton is used is no more than 10 yuan.
Claims (1)
1. formed coal for gasification, it is characterized in that it is is raw material with Jingxi district anthracite fine coal, by add Jingxi district coal gangue and not the compound binding agent formed of quality calcium sulphonate make, the proportioning of moulded coal is: anthracite fine coal content is 90-94%, coal gangue content (fine powder) is 5-9%, and the lignosulfonic acid calcium contents is 0.3-1.5% (weight percent).
