Abstract
The utility model discloses a structure for recycling fine slag discharged by an anthracite water-coal-slurry gasifier. The structure comprises a gasification fine slag discharge pipe (1) for gasification fine slag discharged by the anthracite water-coal-slurry gasifier. The structure is characterized in that a branch pipe (2) is bypassed on the gasification fine slag discharge pipe (1), the gasification fine slag discharge pipe (1) is connected with a flotation charging basket (3), and a discharge hole and a flotation backwater (5) are arranged under the flotation charging basket (3); the branch pipe (2) is connected with a tailing mud charging basket (4), a slag outlet and a squeezing backwater (6) are arranged under the tailing mud charging basket (4), and the flotation backwater (5) and the squeezing backwater (6) both are connected with a gray water storage tank (7). The structure improves the gasification efficiency of the water-coal-slurry, reduces the energy consumption, guarantees the high load and safe and stable operation of a coal chemical industrial production line, and plays a role in leading and demonstration in development of the anthracite water-coal-slurry gasification technology in the coal chemical industry of Guangzhou and China.
Description
Technical field
The recycling structure that the utility model relates to a kind of hard coal coal slurry gasifier and discharges thin slag, belongs to technique and the renovation technique field of vapourizing furnace ash water system.
Background technology
Coal Chemical Industry was all take bituminous coal as raw material in the past, and the grey quantity of slag of generation is little and carbon residue content is low, the having little significance of utilization, and existing treatment process is processed to outsourcing unit for the manufacture of cement and the preparation of coagulation mortar thereof.But be subject to the output of bituminous coal and the restriction in producing region, hard coal coal water slurry gasification is also forced to start promote.Guizhou hard coal output is abundant, but because of reasons such as it exist coal ash fusion temperature high, and ash content is high, and sludge forming performance is poor, causes hard coal coal water slurry gasification technical operation usefulness low, and production cost is high.Analyze reason, it is subject to effect on coal quality, and in anthracitic lime-ash, carbon residue content is higher, and the past discharges or sells to other unit after gasification system is all that thin gasification slag is processed, and without utilization, causing it is one of them reason that usefulness is low.Therefore to discharge the recycling of thin slag be this patent fundamental issue to be solved to hard coal coal slurry gasifier.
Summary of the invention
The technical problems to be solved in the utility model is, providing a kind of reclaims thin gasification slag as raw material and uses, the hard coal coal slurry gasifier of can save production cost, increasing economic efficiency discharges the recycling structure of thin slag, can overcome the deficiencies in the prior art.
Technical solutions of the utility model are:
Hard coal coal slurry gasifier discharges the recycling structure of thin slag, it comprises that hard coal coal slurry gasifier discharges the thin slag delivery pipe of gasification of the thin slag of gasification, the other arm that is connected on the thin slag delivery pipe of gasification, the thin slag delivery pipe that gasifies is connected with floatation feed bucket, is provided with discharge port and flotation backwater below floatation feed bucket; Arm enters charging basket with tail coal mud and is connected, and is provided with slag notch and squeezing backwater below tail coal mud enters charging basket, and flotation backwater is all connected with grey water storage tank with squeezing backwater.
The recycling structure that above-mentioned hard coal coal slurry gasifier discharges thin slag is, is selected into charging basket ingress is provided with flotation valve in the thin slag delivery pipe floating of gasification, and the ingress that tail coal mud enters charging basket on arm is provided with tail coal slurry valve door.
Compared with the prior art, the utility model is according to the feature of hard coal coal slurry gasifier, the thin slag of gasification of hard coal coal slurry gasifier discharge is entered to charging basket with floatation feed bucket and tail coal mud respectively by pump to be connected, enter the cleaned coal obtaining through flotation of floatation feed bucket for the burning of mixing of vapourizing furnace, enter tail coal mud and enter squeezing as coal slime of charging basket and mix burning for coal burning boiler; Waste water after flotation, squeezing is returned grey water storage tank circulation, improve like this gasification efficiency of coal water slurry and reduce energy consumption, guarantee high loading and the safe and stable operation of Coal Chemical Industry production line, carry out and take the lead exemplary role for the development of Guizhou and China's coal chemical technology hard coal coal water slurry gasification technology.Carbon in gasification slag is recycled, simultaneously that final waste residue is non-burning brick for the production of meeting building operation service requirements; Coal water slurry waste liquid is carried out to processing treatment, use it for the production of coal water slurry, realize the recycling of coal water slurry waste liquid, reduce its pollution to environment, and there is good economic benefit.
Economic evaluation: total flotation concentrate is 120 × 0.195=23.4 ton, be converted to feed coal, it is 6.5 tons by moisture content conversion feed coal, the amount of money reclaiming is 6.5 × 850=5525 unit, gasify thin slag by being 500 tons of calculating every day, reclaiming the amount of money every day is 23020.8 yuan, and annual economic benefit is 842.6 ten thousand yuan.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
