Abstract
The utility model provides a novel leatherworking sewage purifying device, which comprises at least two insulation electrolysis pipes, a connecting pipe fitting and a flow distributor. The insulation electrolysis pipes are connected via the connecting pipe fitting to form a curved pipe, the curved pipe is provided with a sewage inlet and a sewage outlet, both the sewage inlet and the sewage outlet are provided with connecting flanges, an anode plate and a cathode plate are longitudinally arranged on the inner wall of each insulation electrolysis pipe and are oppositely arranged in parallel, power wiring ends which are communicated with the corresponding anode plate and the corresponding cathode plate are respectively arranged on the outer wall of each insulation electrolysis pipe, and the power wiring ends are respectively connected with a power output end of the flow distributor. The purifying device is simple and compact in structure, easy in operation and maintenance, small in occupied area and low in operation cost, can effectively remove metal substances such as chromium ions and the like in sewage, and is particularly suitable for leatherworking sewage purification treatment of medium and small-sized leatherworking enterprises.
Description
Technical field
The utility model relates to a kind of tanning sewage treatment unit, relates in particular to a kind of novel tanning sewage refining plant that is applicable to middle-size and small-size leather-making enterprises.
Background technology
Leather industry is the mainstay industry in China's light industry, and in recent years, along with the fast development of tanning industry, China is becoming global tanning production big country, and leather trade the most active, one of market of development potentiality arranged most.Tanning industry is again simultaneously the industry that produces large amount of sewage; In the processing treatment process of leather; Just amount is not big for the sewage that produces; And be that a kind of composition is complicated, the organic waste water of high density, there are materials such as a large amount of chemical substances, heavy metal substance (chromium element) and carboxyl, hydroxyl, carbonyl radical ion in these sewage.These contain harmful sewage of heavy metal, all are directly to be discharged in the rivers without any processing in the past, and environment is caused severe contamination, bring serious destruction to ecology.
At present, generally adopt biological chemistry treating plant and electrolytic process treating plant to handle the sewage that produces in the process hides process in the leather industry.Can effectively administer tanning sewage though use these treating plants; Make it to reach emission standard, still, existing these treating plant investment cost height, complex process, difficult in maintenance; Need more staff to safeguard; And the treating plant floor space is big, and the ratio that the investment of whole treating plant accounts for whole construction investment is very big, for middle-size and small-size leather-making enterprises, almost is difficult to come into operation.Therefore, designing a kind of treating plant that is fit to middle-size and small-size leather-making enterprises is urgent problem.
Summary of the invention
Therefore; Problem to above-mentioned existence; The utility model provides a kind of novel tanning sewage refining plant, and it is simple in structure, compact, and easy handling is safeguarded, floor space is little, working cost is low; And can effectively remove the metallicses such as chromium ion in the decontaminated water, be particularly suitable for the tanning sewage purifying treatment of middle-size and small-size leather-making enterprises.
For realizing above-mentioned purpose; The utility model adopts following technical scheme: a kind of novel tanning sewage refining plant; Comprise at least two bar insulation electrolysis pipelines, connecting tube and RF; The said electrolysis pipeline that respectively insulate connects into the curved shape pipeline through connecting tube, and this curved shape pipeline is provided with sewage inlet and outlet, and sewage inlet and outlet are equipped with joint flange; Each electrolysis inner-walls of duct that insulate is provided with positive plate and negative plate along the longitudinal direction; Said positive plate and negative plate opposing parallel are provided with, and each electrolysis pipeline outer wall that insulate is respectively equipped with the supply terminals that is communicated with positive plate and negative plate, and said each supply terminals is connected with the power output end of RF respectively.
Preferably, the distance between said positive plate and the negative plate is 140～160mm, and length is 20～35m.
Through adopting technique scheme; The beneficial effect of the utility model is following: the utility model is arranged to the curved shape pipeline with insulating electrolysis pipeline; Length through adjustment direct supply or lengthening positive plate and negative plate prolongs electrolysis time then; Chromium ion in the tanning sewage is adsorbed by positive plate, form the chromium metal of solid particulate, these chromium metals are recyclable to be utilized again; Materials such as the carboxyl in the tanning sewage, hydroxyl, carbonyl radical ion are adsorbed by negative plate in addition, thereby make tanning sewage reach emission standard or recycling in addition, have practiced thrift water resources.The refining plant of the utility model is simple in structure, compact, simple to operate, and is easy to safeguard that a staff can control fully, has saved manpower; This refining plant floor space is little in addition, less investment, working cost are low, and the sewage purification that is particularly suitable for middle-size and small-size leather-making enterprises is handled.

Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
Embodiment: please refer to Fig. 1, the utility model embodiment discloses a kind of novel tanning sewage refining plant, comprises three bar insulation electrolysis pipelines 1, connecting tube 2 and RF (not shown); Said connecting tube 2 is a U type pipe fitting; Each electrolysis pipeline 1 that insulate connects into S type curve pipeline through this connecting tube 2, and this S type curve pipeline is provided with sewage inlet and sewage outlet, and sewage inlet is provided with joint flange 11; Sewage outlet is provided with joint flange 12; The tanning sewage pipe is communicated with sewage inlet through joint flange 11, and other discharge tubes of joint flange 12 and other of said sewage outlet are connected, and makes after the electrolysis; The sewage that reaches emission standard is discharged from other discharge tubes; This S type curve pipeline can effectively prolong electrolysis time, and each electrolysis pipeline 1 inwall that insulate is provided with positive plate 3 and negative plate 4 along the longitudinal direction, said positive plate 3 and negative plate 4 opposing parallel settings; Each electrolysis pipeline 1 outer wall that insulate is respectively equipped with the supply terminals 5 that is communicated with positive plate 3 and negative plate 4, and said each supply terminals 5 is connected with the power output end of RF respectively.The direct supply of said insulation electrolysis pipeline 1 obtains through rectifier rectification, and for safety, the voltage of the direct supply of insulation electrolysis pipeline 1 adopts the safety voltage of 36V; And the distance between positive plate 3 and the negative plate 4 is 155mm; The length of positive plate 3 and negative plate 4 is 25mm, and sewage carries out electrolysis time through insulation electrolysis pipeline 1 and is no less than 3min, and the chromium ion in the tanning sewage is adsorbed by positive plate 3; Form the chromium metal of solid particulate, these chromium metals are recyclable to be utilized again; Materials such as the carboxyl in the tanning sewage, hydroxyl, carbonyl radical ion are adsorbed by negative plate 4 in addition, thereby make tanning sewage reach emission standard or recycling in addition, have practiced thrift water resources.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; Concrete this technical scheme method of realization and approach are a lot; The above only is the preferred implementation of the utility model, but the those skilled in the art should be understood that in the spirit and scope of the utility model that does not break away from appended claims and limited; Can make various variations to the utility model in form with on the details, be the protection domain of the utility model.
