Description

The tripping device of carbide slag slurries and silicon iron in wet method acetylene

Technical field

The utility model relates to the tripping device of carbide slag slurries and silicon iron in a kind of wet method acetylene.

Background technology

At present, the carbide slag slurries produced in wet method acetylene process and the silicon iron particle wherein carried secretly follow-up along with carbide slag slurries enters together production equipment conveying and use, there is following problem: 1, silicon iron hardness is large, carry with carbide slag slurries, erosive wear can be carried out to the pipeline, equipment, valve etc. of conveying, cause the damages such as pipeline, equipment, valve, increase the checking maintenance cost of chemical production device.2, silicon iron particle enters acetylene gas retrieving arrangement with carbide slag slurries, because the silicon iron in carbide slag slurries makes it damage perforation to erosive wears such as retrieving arrangement pipeline, equipment, valves, air will be caused to enter slag slurry acetylene gas recovery system and cause security incident.3, silicon iron particle is carried with carbide slag slurries, because the silicon iron in carbide slag slurries makes it damage perforation to handling equipment erosive wear, if non-Timeliness coverage will make carbide slag slurries leak in ambient soil, water quality and cause environmental pollution.

Utility model content

Technical problem to be solved in the utility model is to provide the tripping device of carbide slag slurries and silicon iron in a kind of wet method acetylene, can reduce the wearing and tearing to the pipeline of conveying, equipment, valve of silicon iron in carbide slag slurries.

Realizing principle of the present utility model is: the carbide slag slurries produced in wet method acetylene process is delivered to silicon iron separator and carries out centrifugation, heavy silicon iron is settled down to separator bottom under gravity, recycle after silicon iron drain separator, the carbide slag slurries that proportion is little is discharged from the overflow of silicon iron separator upper end, after entering slag slurry surge tank, acetylene gas is reclaimed, then is transported to cement mill through Pulp pump and carries out follow-up technique.

The technical scheme adopted based on above-mentioned principle the utility model is: the tripping device of carbide slag slurries and silicon iron in wet method acetylene, comprise silicon iron separator, silicon iron separator is communicated with slag slurry inlet pipe, also comprise slag slurry surge tank, the upper end of silicon iron separator is communicated with by upflow tube with the upper end of slag slurry surge tank, the top of silicon iron separator and slag slurry surge tank top are connected with gas-liquid equilibrium pipe, gas-liquid equilibrium pipe makes the pressure between silicon iron separator and slag slurry surge tank keep balance, be beneficial to carbide slag slurries and overflow to slag slurry surge tank, silicon iron separator bottom is communicated with scum pipe, silicon Tie Tong after isolated crosses scum pipe and discharges and reclaim.

Further, slag slurry surge tank bottom is connected with Pulp pump in turn, reclaims de-parser, after carbide slag slurries enters slag slurry surge tank, is deposited to after being discharged by pipeline by slag slurry surge tank bottom, delivers to reclaim de-parser through Pulp pump.

Further, knife gate valve and lower knife gate valve on scum pipe is provided with, use this knife gate valve can improve the closedown sealing property of delivery pipeline system, and the silicon iron stopped to greatest extent in scum pipe leaks, upper knife gate valve and lower knife gate valve with the use of, avoid scum pipe blocking.

The beneficial effects of the utility model are:

(1) the silicon iron particle in carbide slag slurries is separated by silicon iron separator from carbide slag slurries, silicon iron in minimizing carbide slag slurries is to the wearing and tearing of subsequent delivery device, reduce Chemical Manufacture checking maintenance cost, sell outside the silicon iron simultaneously reclaimed, also create certain economic benefit, ensure that the continuity of whole system.

(2) in the wet method that puts into operation acetylene carbide slag slurries after silicon iron particle sorting apparatus, decrease silicon iron in carbide slag slurries to the wearing and tearing of reclaiming acetylene gas device, avoid because retrieving arrangement wearing and tearing or perforation enter air and security incident occurs, improve the security and stability of carbide slag slurries acetylene gas retrieving arrangement.

(3) in the wet method that puts into operation carbide slag slurries after silicon iron particle sorting apparatus, decrease slag slurry in silicon iron to the wearing and tearing of carbide slag slurries handling equipment, avoid the environmental pollution that handling equipment fault is brought.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model tripping device.

Be labeled as in figure: 1-silicon iron separator, 2-slag slurry inlet pipe, 3-slag slurry surge tank, 4-upflow tube, 5-gas-liquid equilibrium pipe, 6-Pulp pump, 7-reclaims de-parser, the upper knife gate valve of 8-, the upper knife gate valve of 9-.

Embodiment

Below in conjunction with drawings and Examples, the utility model is further illustrated.

As shown in Figure 1, slag slurry is after slag slurry inlet pipe 2 enters silicon iron separator 1, carbide slag slurries is separated through centrifugal settling with silicon iron particle, after the silicon iron be settled down to bottom silicon iron separator 1 is discharged by scum pipe, discharge through upper knife gate valve 8 and lower knife gate valve 9 and reclaim, carbide slag slurries enters slag slurry surge tank 3 from silicon iron separator 1 top automatic overflow, and then be delivered to the de-parser 7 of recovery by Pulp pump 6, in whole process, in carbide slag slurries, the unreacted calcium carbide of part continues reaction generation acetylene gas, finally reclaims acetylene gas in the de-parser 7 of recovery.

In work, first open lower knife gate valve 4, scum pipe is rinsed, slag slurry in scum pipe is rinsed out, and then open knife gate valve 3 and carry out deslagging, the deslagging that the slag slurry avoided because revealing from upper knife gate valve 3 blocks scum pipe and causes is smooth, and upper knife gate valve 3 and lower knife gate valve 4, by its switch of procedure auto-control, realize intermittent automatic-discharging silicon iron particle.

Do not adopt in carbide slag slurries before silicon iron particle sorting apparatus, the slag slurry valve in retrieving arrangement uses 6 months and just occurs wearing and tearing perforated phenomenon, and channel bend uses 1 year and occurs wearing and tearing perforated phenomenon; Adopt in carbide slag slurries after silicon iron particle sorting apparatus, slag slurry valve can use more than 2 years continuously, and channel bend has no noticeable wear, meanwhile, saves the expense changing valve and elbow, ensure that the continuity of whole system.

After in wet method acetylene of the present utility model, the tripping device of carbide slag slurries and silicon iron puts into operation, decrease silicon iron in slag slurry and conveying device and carbide slag slurries acetylene gas retrieving arrangement, pipeline, the wearing and tearing of valve or perforation are continued to carbide slag slurries, avoid because retrieving arrangement wearing and tearing or perforation enter air and security incident occurs, eliminate potential safety hazard.
