Description
Technical field
The utility model relates to the phosphorization treatment process apparatus field, is specifically related to be used for the water-saving and emission-reducing system of the without phosphorus pre-treating technology of paint line.
Background technology
Paint line is owing to exist a lot of chemical treatments operations and washing step, a large amount of water need be used and consume to production process, the washing purpose is to wash the treatment fluid on coated article surface off, and it is to remove foreign ion (reach the electricity that drips lead be not more than 30uS) that final pure water is washed; The principle of washing is physical actions such as dilution, displacement.Generally will reach the wash degree of technological requirement, need washing 2--4 time, each washing needs 10 times running water (or the oligosaprobic rinse water) cleaning of coated article institute with liquid measure, just can reach the 1/100--1/1000 of former treatment fluid concentration after washing for 2--3 time.Traditional phosphatization pre-treatment water system is example as several modes once with the flat cold-rolled sheet.
First kind: hot water wash → pre-degreasing → degreasing → washing 1 → washing 2 → table accent → phosphatization → washing 3 → washing 4 → deionization washing, each rinsing bowl is independently added fresh tap water, and by the overflow discharging, water consumption is very big, water use efficiency low (as Fig. 3).
Second kind: contrary operation moisturizing method is by spraying or directly add last one rinsing bowl operation with fresh tap water, contrary operation overflows to preceding one washing step, be about to the low rinse water of dustiness and constantly add to preceding road washing step, reduce the dustiness of rinse water, to the most preceding one rinsing bowl overflow discharging.
For example, hot water wash → pre-degreasing → degreasing → washing 1 → washing 2 → table accent → phosphatization → washing 3 → washing 4 → deionized water.
Contrary operation overflow is in proper order: washing 2 overflows to washing 1 discharging, and deionized water overflows to washing 4, washing 4 overflows to washing 3 dischargings (as Fig. 4) again.
The third: pre-hydro-peening method, it is to be changed into pre-hydro-peening (jet pipe be arranged between two-step on the draining section) on the contrary basis of operation moisturizing method by overflow, the water that flows down from coated article flows into (adding) preceding working procedure, make the treatment fluid minimizing of processed next procedure (be not less than 20% approximately, comparatively speaking, work to increase washing times), the utilization rate of raising cleaning efficiency and water reduces the consumption of rough medicament.
In sum, though through years of development, the paint line water saving has had very big improvement, but do not reach perfect stage, still caused a large amount of wastes, and China's water scarcity on a large scale, per capita 1/4 of the not enough world of freshwater resources quantity per capita, and it is very uneven to distribute.Having more than 400 in the big and medium-sized cities, the whole nation is the lack of water city, and wherein 100 is the city of severe water shortage.The shortage of water resources problem more and more becomes the key factor of restriction China's economy and social development.Along with becoming better and approaching perfection day by day of Environmental Protection in China rules, sewage discharge rules, the problem of environmental protection has been subjected to the attention of height, and the standard of sewage discharge improves day by day, and the sewage disposal expense also day by day rises.How to design, formulate rational manufacturing technique for painting dressing, guaranteeing reasonable use of water, using water wisely under the product quality premise, farthest reduce the consumption and the quantity of wastewater effluent of water, be not only the long-term goal of Business survival, also become a big problem that involves the interests of the state and the people.
The utility model content
It is a kind of reasonable in design that technical problem to be solved in the utility model is to provide, utilize the existing pipeline of contrary operation moisturizing method transformation, the water overflow of one rinsing bowl in back is discharged into preceding road rinsing bowl, the step mode is arranged to connect, rationally utilize rinse water, compare with each section draining, can save the water-saving and emission-reducing system of the without phosphorus pre-treating technology of paint line of rinse water consumption and wastewater treatment in a large number.
Technical problem to be solved in the utility model realizes by the following technical solutions,
A kind of water-saving and emission-reducing system that is used for the without phosphorus pre-treating technology of paint line, comprise degreasing, rinsing bowl 1, rinsing bowl 2, rinsing bowl 3, without phosphorus conversion, wash 4 pumps, rinsing bowl 5, rinsing bowl 6 processing apparatus, it is characterized in that: on described rinsing bowl 6, be connected to the running water water inlet, rinsing bowl 1 is provided with a sewage effluent, rinsing bowl 1 to rinsing bowl 6 connects by pipeline series connection step mode, described rinsing bowl 4 pump discharge places increase a three-way pipe, rinse water overflows to rinsing bowl 5 from rinsing bowl 6 and overflows to washing 4 pumps again, rinsing bowl 3 overflows to rinsing bowl 2, and to overflow to rinsing bowl 1 again be to utilize liquid-level difference principle, and to flow to rinsing bowl 3 be to utilize the three-way pipe that increases at washing 4 pump discharge places to carry out to force adverse current and wash 4 pumps.
Rinsing bowl 1 described in the utility model further to rinsing bowl 6 connects by pipeline series connection step mode, utilize liquid-level difference principle, adopting the nature adverse current that rinse water is overflowed to rinsing bowl 5 from rinsing bowl 6 overflows to washing 4 pumps and overflows to rinsing bowl 3 and overflow to rinsing bowl 2 and overflow to rinsing bowl 1 again, because having table, without phosphorus conversion process do not transfer operation, so when washing 4 pumps overflow to rinsing bowl 3, the pH value of water lotion is a faintly acid, to not influence of workpiece, so only need to wash 1 groove lower end and establish a discharge outlet, can guarantee that the cleaning quality of workpiece can save the treating capacity of the consumption and the waste water of rinse water again in a large number in first road.
The beneficial effects of the utility model are: the rinsing bowl of whole technology is set to a row of cells place system, utilize liquid-level difference principle to adopt back segment washing feedwater, supply water to the overflow of leading portion rinsing bowl in turn, the whole washing step step mode that is arranged to connect, theory can be economized on water more than 40%, the consumption of not only saving rinse water has also reduced the treating capacity of waste water significantly, thereby saves production cost.
