Description
Technical field
The utility model belongs to metal material cleaning technique field, relates in particular to alkali mist purifying waste retracting device.
Background technology
At present, produce the iron and steel enterprise of the kinds such as cold rolled silicon steel, in order to meet product quality and technological requirement, generally all steel plate is carried out to cleaning by degreasing, and the cleaning by degreasing technology of cold-strip steel is very ripe.
Common band steel cleaning by degreasing process route is scrub → clear water of scrub → electrolytic cleaned → clear water of alkali spray → alkali hydro-peening → heated-air drying.In strip cleaning process, degreasing medium used is generally in 60～90 ℃ of temperature ranges, and temperature is higher, and it is 300-500mg/m that use has certain corrosivity concentration
3naOH alkali lye, it has certain corrosivity to environment and structures around, and alkali lye is spray regime in rinse bath, has further strengthened the volatilization of alkali lye.
The position that whole unit produces alkali mist steam has: alkali lye spray tank, alkali lye are scrubbed groove, electrolytic cleaning tank, water and scrubbed groove, heat water-spraying's groove etc.Most of cleaning tape steel units all arrange a set of alkali mist treatment system and guarantee environmental protection, realize qualified discharge.Alkali mist treatment system comprises the compositions such as draught hood, airduct, scrubbing tower and circulating pump thereof, blower fan, exhaust chimney.The alkali mist waste gas that unit is collected is sent into scrubbing tower through airduct, in tower, alkali fog body is carried out to spray-absorption, reaches design discharge standard (<10mg/m
3) after enter atmosphere by blower fan through the high exhaust chimney of 20m, waste liquid drains in effluent pit by overflow pipe.
Liquid waste concentration 1%, temperature 40-50 ℃, and very pure, 1 cubic meter left and right per hour.Discharge waste liquid carries out chemical analysis contrast with the alkali lye of normal production and application, detects iron part and oil content index and concentration, and result is as follows:
| All kinds of indexs | Alkali concn | Iron part | Oil content |
| Discharging any waste liquor representative value | 1％ | ≤56ppm | ≤1000ppm |
| Normal alkali lye representative value | 3％ | ≤600ppm | ≤2000ppm |
Require alkali lye technic index to be for alkali cleaning degreasing: concentration of lye 3-5%; Alkali spray, alkali brush oil content≤8000ppm, iron part≤600ppm, electrolysis oil content≤2000ppm, iron part≤600ppm; The contrast of visible and discharging any waste liquor analysis result, discharging any waste liquor be concentration lower than technological requirement, other index is better than technological requirement far away.So as long as concentration adjustment can be recycled completely.
Utility model content
The purpose of this utility model is to overcome the problems referred to above and provides a kind of alkali mist purifying waste recycling device with deficiency, and device is simple, easy to operate, uses safety, saving Energy Intensity Reduction cost.
A kind of alkali mist purifying waste recycling device, above alkali cleaning circulating tank, the other return water tank that arranges of alkali spray Rose Box, efflux wastewater pipeline is divided into two branch roads, article one, efflux wastewater branch road connects return water tank by valve, the casing top of return water tank arranges degreasing agent dog-house, the top, casing side of return water tank arranges overfall, overfall is connected with efflux wastewater pipeline, return water tank casing below arranges evacuation port, evacuation port is all connected with efflux wastewater pipeline by valve, return water tank box house arranges two dividing plates, the dividing plate (9) of close overfall one side is higher than wherein 100mm of the dividing plate away from overfall, solve filter deposition problem, return water tank casing one side-lower arranges and reclaims alkali lye pipeline apart from 300-400mm place at the bottom of case, return water tank by reclaim alkali lye pipeline and on valve connect unit alkali lye circulating tank.
The beneficial effects of the utility model are:
(1) can realize waste liquid recycling;
(2) can realize the zero-emission of alkali mist purifying waste;
(3) guarantee that concentration of lye is uniform and stable in process of production;
(4) realize cost efficiency, energy-saving and emission-reduction.
Accompanying drawing explanation
Fig. 1 is alkali mist purifying waste recycling structure drawing of device schematic diagram.
In Fig. 1,1 is return water tank, and 2 is unit alkali lye circulating tank, and 3 is degreasing agent dog-house, and 4 for reclaiming alkali lye pipeline, and 5 is valve, and 6 is evacuation port, and 7 is overfall, and 8 is dividing plate, and 9 are, 10 is discharging any waste liquor pipeline.
The specific embodiment
As shown in Figure 1, alkali mist purifying waste recycling device, with efflux wastewater displacement 1m
3/ h is example, above alkali cleaning circulating tank, the other high return water tank for 500*500*800mm of the wide * of long * that arranges of alkali spray Rose Box, efflux wastewater pipeline is divided into two branch road 10-1,10-2, when unit does not need or produces extremely and close, directly drain as current direct discharge operation procedure, if unit normally starts, constantly fluid infusion makes full use of the recovery values such as its efflux wastewater and concentration and temperature, use with the liquid of temperature and continue to dissolve, artificially stir if desired, guarantee its concentration.
Efflux wastewater branch road 10-2 connects return water tank 1 by valve 5, and the casing top of return water tank 1 arranges degreasing agent dog-house 3, and 3 openings that feed intake are diameter 300-500mm; Top, the casing left side overfall 7 of return water tank 1, overfall 7 is connected with efflux wastewater pipeline 10-1, the casing below of return water tank 1 arranges evacuation port 6, evacuation port 6 is all connected with efflux wastewater pipeline 10-1 by valve 5, and box house arranges dividing plate 8,9, near overfall) dividing plate 9 of a side is higher than the dividing plate 8 away from overfall 7, the high 600-700mm of dividing plate 9, the high 500-600mm of dividing plate 8, dividing plate 9 differs 100mm with dividing plate 8, solves filter deposition problem; Casing right side below arranges apart from casing 300-400mm place reclaims alkali lye pipeline 4, return water tank 1 by recovery alkali lye pipeline 4 and on valve 5 connect unit alkali lye circulating tank 2.
