Description
Technical field
The utility model relates to carbide slag washing process field, especially a kind of carbide slag washing dechlorination device.
Technical background
Solid waste carbide slag for the generation of PVC enterprise, because entering of a large amount of chlorine-contained wastewaters that discharge in the chlor-alkali Workshop Production process, wherein containing very high salinity (mainly is villaumite, reach as high as 0.2%), make the treatment and disposal and the recycling of carbide slag run into various difficulties, such as utilizing carbide slag to produce the cement field as calcareous raw material, national standard has just been done clearly regulation to the content of chlorine in the calcareous raw material, requires it to surpass 0.03%.Therefore necessary carbide slag is washed pre-treatment, reduce the content of objectionable constituent such as villaumite.
Mentioning in the Chinese invention patent 03825874.9 sprays water flying ash when mobile on pressure filter simultaneously washes desalination, wash desalination immediately, have advantages such as equipment is simple, easy and simple to handle, occupation of land is little, but there are associated problem such as washing institute water requirement is big, dechlorination effect is not good in this patented technology.
Adopt secondary water washing technology in China's utility model patent 200820130430.5, equipment adopts an agitated pool+primary sedimentation basin+secondary stirring pond+secondary sedimentation basins to be provided with, there are a plurality of problems in this equipment: 1, do not have washing cycling utilization of wastewater scheme, produce a large amount of waste water, increased the washing cost and the pressure of waste water control; 2, patent adopts natural gravity to be deposited in the mud-water separation effect and is much worse than press filtration, dewatering such as centrifugal greatly, thereby will cause the decline of washing dechlorination effect or the rising of water consumption.
Summary of the invention
The purpose of this utility model is a kind of water-saving of design and dechlorination effect is good, simple in equipment, floor space are little, stable carbide slag washing dechlorination device, and because the waste water salt concentration after the washing is higher, to cause secondary pollution after draining into water body, so the utility model carries out recycle to washing waste water under the situation that does not influence the washing effect.
A kind of carbide slag water washing device comprises water wash system, solid-liquid separation system, waste water reuse system and circulation line, wherein has circulation line to connect between water wash system, the solid-liquid separation system, and carbide slag slurry is reciprocation cycle between each device.Have pipeline to interconnect between solid-liquid separation system and the waste water reuse system, the waste water that solid-liquid separation system produces by waste water reuse system purify store after again as the washing water circulation use of water wash system.
Described water wash system comprises circular washing pool, slush pump and stirring instrument.
Described solid-liquid separation system comprises radical sedimentation basin and belt filter press.
Described waste water reuse system comprises electrolysis dechlorination pond and reuse water collecting tank.Wherein electrolysis dechlorination pond comprises rectangular parallelepiped pond body, negative plate, positive plate and gas sweetening collection device, and it is parallel that the limit is grown in negative plate, positive electricity pole plate and pond, according to actual requirement of engineering configured electrodes plate quantity.The reuse water collecting tank is used to collect the waste water after electrolysis dechlorination pond purifies, and water wash system washing water is provided.
Described circulation line comprises slurries circulation line, reuse water circulation line.
During the operation of the utility model device, the carbide slag slurries that factory discharges is sent into circular washing pool, use from the reuse water mixing fresh supplemented water of reuse water collecting tank and wash, starting the stirring instrument simultaneously stirs, make solid-liquid fully contact mutually, the slurries after stirring pump into radical sedimentation basin by slush pump.Slurries obtain supernatant liquor and carbide slag slurries in the radical sedimentation basin natural sedimentation, and supernatant liquor goes to electrolysis dechlorination pond to flow through between cathode-anode plate, and villaumite is generated chlorine and enters into the gas sweetening collection device with other electrolytic waste gas by electrolysis, obtains pure gas.Waste water flows into the reuse water collecting tank after removing chlorine, the carbide slag that precipitates detects whether reach the washing requirement, the carbide slag slurries that does not reach the washing requirement flows back to circular washing pool, the slurries that reach the washing requirement enter the belt filter press dehydration, obtain filtrate and carbide slag filter cake, filtrate still flows to electrolysis dechlorination pond, and the carbide slag filter cake is delivered to the warehouse by belt conveyor.
The utlity model has following beneficial effect:
1. increased waste water reuse system, the unit's of greatly reducing carbide slag washing water loss, and do not wash effluxing of waste water;
2. increase the filter-press dehydration device, improved dechlorination effect.

Embodiment
Embodiment 1
A kind of carbide slag water washing device comprises water wash system, solid-liquid separation system, waste water reuse system and circulation line, and water wash system comprises a circular washing pool 1, slush pump 12 and stirs instrument 2; Solid-liquid separation system comprises a radical sedimentation basin 3 and a belt filter press 4; The reuse water recycle system comprises electrolysis dechlorination pond 6 and a reuse water collecting tank 5, and wherein electrolysis dechlorination pond comprises rectangular parallelepiped pond body 16, negative plate 19, two positive plates 17 and gas sweetening collection devices 18; Circulation line comprises slurries circulation line, reuse water circulation line, Parallel Slide Valves 15 and filter cake conveying belt 8, the slurries circulation line comprises first pipeline 7, second pipeline 11, the 3rd pipeline 14 and Parallel Slide Valves 15, and the reuse water circulation line comprises the 4th pipeline 9, the 5th pipeline 10, the 6th pipeline 13.Wherein connected by the slurries circulation line between water wash system, the solid-liquid separation system, carbide slag slurry is reciprocation cycle between each device, when the washing effect reaches requirement, opens Parallel Slide Valves 15, and slurries enter solid-liquid separation system.Interconnect by the reuse water circulation line between solid-liquid separation system and the waste water reuse system, the waste water that solid-liquid separation system produces by waste water reuse system purify store after again as the washing water circulation use of water wash system.
