Abstract
The utility model belongs to the field of pulverized coal gasification technologies, and particularly relates to a coal slime conveying device which comprises a belt conveyor, middle storage bins, hydraulic screw feeding devices, high-pressure wet ash pumps and wet ash pipelines. At least one belt unloader is arranged on the belt conveyor along a conveying direction, the middle storage bins correspond to the belt unloaders, the quantity of the middle storage bins is equal to that of the belt unloaders, at least one discharge outlet is formed in the bottom of each middle storage bin, valves are mounted at the bottoms of the middle storage bins, each discharge outlet is connected with a feed inlet of the corresponding hydraulic screw feeding device, an outlet of each hydraulic screw feeding device is connected with an inlet of the corresponding high-pressure wet ash pump, and an output end of each high-pressure wet ash pump is communicated with a wet ash adding opening of a corresponding user via the corresponding wet ash pipeline. The coal slime conveying device has the advantages that the original design scheme is changed, and gasified filter cakes are used as co-combustion raw materials of boilers in a design principle, so that the investment and corresponding consumption are reduced; occupied filter cake storage places are reduced, and underground water pollution of plant areas due to water in the filter cakes is eliminated.
Description
Technical field
The utility model belongs to the bed pulverized coal gasification technology field, particularly relates to a kind of coal slime conveying device.
Background technology
According to on-the-spot running condition, the buck that in space flight stove gasifying powder coal device, gasification furnace produces obtains wet ash (claiming again the gasification filter cake) through vacuum filter, its carbon content is about 30%, there is higher calorific value (dry base low heat valve is about 3000kcal/kg), and the wet ash (moisture wet basis is about 50%) that the separate unit gasification furnace produces is about 15t/h, the wet ash of this part has taken large stretch of storage space, has caused site environment poor.Because the ash amount is larger, sell and be difficult to find stable client as waste material, directly abandon and caused huge energy dissipation.My company once designed the filter cake that will gasify as brick-making raw material, but its moisture is higher, the brickmaking process is gone out moisture could moulding, therefore must just can complete whole technique by consumption of calorie, brickmaking technology and corresponding dry run are all wanted corresponding investment simultaneously, and cost of investment is higher.
Summary of the invention
The technical problems to be solved in the utility model overcomes above-mentioned the deficiencies in the prior art exactly, and a kind of poor problem of site environment that can solve is provided, and can save again the energy, and have the coal slime conveying device of good economic benefits simultaneously.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of coal slime conveying device, comprise belt feeder, middle warehouse, the hydraulic screw charging gear, the wet grey pump of high pressure and wet grey pipeline, be provided with at least one belt tripper along the conveying direction on described belt feeder, the middle warehouse that be provided with equal number corresponding to belt tripper, middle warehouse bottom at least is provided with a discharging opening and valve is installed, each discharging opening is connected with corresponding hydraulic screw charging gear feeding mouth, the outlet of hydraulic screw charging gear is connected with wet grey high pressure pump entrance, the wet grey pump output terminal of high pressure is connected by wet grey pipeline and the wet ash interpolation mouthful of user.
Described belt tripper has three.
Described middle warehouse bottom discharge mouth has one or two.
Described belt feeder, middle warehouse, hydraulic screw charging gear, the wet grey pump unification of high pressure are arranged in wet grey pump house.
Described user is positioned at indoor and is provided with charging gear.
Described valve is the maintenance gate valve.
Be provided with the cleaning counter flow pipe on described boiler feeding device simultaneously.
The beneficial effect of technical solutions of the utility model is:
1, structurally, the utility model has changed original design plan, and the filter cake that will gasify on principle of design is as Boiler Mixed Burning raw material, reduce cost and corresponding consumption; Reduce the taking of filter cake storage space simultaneously, eliminated filter cake moisture to plant area's groundwater contamination.
2, structurally, the utility model filter cake that will gasify is delivered to the user with high pressure pump, has improved the system automation degree, has reduced personnel, facility and associated administering and maintaining, and has saved the daily attention expense; By enforcement of the present utility model, can improve the gasification installation ambient environment, reduce the coal dust dust pollution, contribute to environmental protection and workman healthy.
3, structurally, the utility model utilizes on-site to have user-CFBB now, and the gasification filter cake is carried out to drying, has improved the system equipment degree of utilization; Simultaneously, filter cake has relatively long length of the halt in CFBB, can fully guarantee drying effect, is the application to the CFBB process characteristic.
4, in addition, the gasification filter cake by the utility model dry run because participating in the CFBB combustion process, utilize its combustion performance to produce steam, fully reclaim the heat in fuel, energy conservation and consumption reduction effects is obvious; And after burning, formed dry ash is sold as product, remarkable in economical benefits.
