Description
Technical field
The utility model belongs to the Pneumatic Conveying Technology field, particularly a kind of long-distance pipe closed cycle air-transport system that is applicable to the carbide mud residue of calcium carbide dry method acetylene processed.
Background technology
" newly-built, reorganization and expansion generated by polyvinyl chloride by calcium carbide project is the carbide mud residue comprehensive utilization device such as auxiliary construction carbide mud residue cement processed simultaneously for regulation in the chlor-alkali industry entry criteria (revised edition in 2007) of National Development and Reform Committee 2007 No. 74 bulletin." as seen the effective processing for carbide mud residue seemed very important.
At present, it is the bottleneck that restricts the chemical enterprise development take calcium carbide as basic material such as calcium carbide process PVC that carbide mud residue is processed, 1 ton of PVC of every production will produce 1.5～1.9 tons of solid-state calcium hydroxides (carbide mud residue), not only need to take a large amount of soils, also can cause environmental pollution.In the existing chemical enterprise, mostly be wet method acetylene processed, water consumption is larger in the production process, has produced wet carbide mud residue and waste liquid, and environmental pollution is heavy.The carbide mud residue that wet method acetylene processed produces is moisture 90%, and still moisture 34%～40% after press filtration, recycling needs treated, could be as the raw material of cement production device, and disposal cost is higher; Affected greatly the economy of carbide mud residue comprehensive application.
And moisture 4%～12% in the carbide mud residue of dry method acetylene processed, can directly recycle, with the obvious advantage at aspects such as energy-conservation, water saving, environmental protection and carbide mud residue comprehensive application cement projects processed.Therefore, country encourages dry method acetylene processed, large-scale converter, pressure-variable adsorption, without the exploitation of the generated by polyvinyl chloride by calcium carbide technologies such as mercury catalyst, encourages newly-built carbide mud residue cement production device employing processed new dry process for cement production.Utilizing the dried slag of calcium carbide to produce cement, is the important model of " resource-production-product-consumption-waste-renewable resources " recycling economy development, is thoroughly to eliminate carbide mud residue to atmosphere, pollution of waterhead effective ways.
In the technique of dry method acetylene processed, be unusual important step for the conveying of carbide mud residue.The carbide mud residue of at present dry method acetylene generation processed is carried and is usually adopted FU chain-linked conveyer or pipe conveyer.
Wherein, the FU chain-linked conveyer is a kind of airtight mechanical load transfer device, and course of conveying need to be used nitrogen protection, but this equipment fed distance is short, and operational throughput is little, serious wear in use, and when material moisture surpasses 5%, easily stop up; When the acetylene gas content overproof, easily produce blast.For pipe conveyer, it is reinforced, discharge process all is to open wide operation, the carbide mud residue powder of 10～50um can wave with the wind, cause serious environmental pollution, in addition, the pipe conveyer floor area is large, the maintenance maintenance amount is large, and can only single-point reinforced, single-point discharging, if will satisfy the requirement of multiple discharge, need again transhipment.
This shows, all there are certain defect in the feedway and the mode of movement that are used at present the carbide mud residue of dry method acetylene generation processed, thereby have restricted effective utilization of dry method acetylene technique processed.
