The beneficial effects of the utility model:Air-floating processing apparatus of the present utility model based on electrochemical techniques, including gas Floating pond, power module and slag-scraper, the flotation tank by dividing plate be separated into interconnected gas-producing area, Disengagement zone and Gathering ground, the water inlet connected with gas-producing area and the delivery port connected with gathering ground, the gas-producing area are provided with flotation tank Inert electrode plate is inside provided with, power module forms water electrolysis system with inert electrode plate, and the slag-scraper includes being used to receive Collect the collection flitch of scum silica frost, be arranged on the scum pipe of collection flitch side and be arranged on above collection flitch be used for will collection flitch floating Slag is scraped scrapes slag structure into scum pipe.The air floatation wastewater treatment device of the structure, based on electrochemical techniques, produced using by electric energy The air-float method of raw microbubble, its caused bubble hydrogen particle diameter is 10~30um, not soluble in water, and its capacity is the 1/ of water capacity 11200, bubble capture ability is stronger than the ability of pressure floatation air, air-dissolving air-float.Bubble hydrogen grain is at 20 DEG C caused by electrochemistry air supporting When its averag density be 0.5g/L, much smaller than general atmospheric density, its floating loading capability is twice than pressure floatation air and air-dissolving air-float More than, therefore effectively increase wastewater purification efficiency and effect.
Brief description of the drawings
The utility model is further described with reference to the accompanying drawings and examples.
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in detail below with reference to accompanying drawing, as shown in Figure 1:The utility model provides one kind Air-floating processing apparatus based on electrochemical techniques, including flotation tank 1, power module 2 and slag-scraper, the flotation tank pass through Dividing plate is separated into interconnected gas-producing area 3, Disengagement zone 4 and gathering ground 5, and entering of being connected with gas-producing area is provided with flotation tank The mouth of a river 6 and the delivery port 7 connected with gathering ground, flotation tank are made of one kind of stainless steel, carbon steel or PP plastics, the production Inert electrode plate 8 is provided with gas area, inert electrode plate includes minus plate and positive plate, minus plate and the spacing of positive plate interval one From being arranged in juxtaposition, inert electrode plate quantity, area, sheet separation according to circumstances can be convenient according to actual conditions with independent assortment Debugged, power module forms water electrolysis system with inert electrode plate, and power module is high-frequency direct-current Switching Power Supply, and high frequency is straight Current switching power supply is by IGBT module controlling switch frequency in 50-100kHz scopes, and efficiently, energy-conservation, operating efficiency reaches 90% More than, direct current output waveform is high frequency square wave, and ripple factor is less than 1%, reduces battery lead plate passivation, and battery lead plate service efficiency is big Big enhancing, collection flitch 9 that the slag-scraper includes being used to collect scum silica frost, it is arranged on the scum pipe 10 for collecting flitch side and sets Put and scrape slag structure into scum pipe for collection flitch floating slag to be scraped above collection flitch, the slag structure of scraping includes reciprocal fortune Dynamic chain 11 and the polylith scraper plate 12 being disposed on side by side on chain, the chain both sides are supported by sprocket wheel 13, chain Bar is driven by worm speed reducer.This equipment has related parameter as follows:1) determination of gas production;Using inert electrode plate, it is produced Tolerance has direct relation with the current strength loaded on pole plate, it is generally the case that loading current intensity is 1 with aerogenesis magnitude relation It is 0.63L/h that Ampere currents, which produces gas flow,;2) determination of unit power;This plant capacity major embodiment is in high frequency switch power Power output, it is generally the case that output power of high-frequency switching power supply needed for specific discharge is 0.5kW/ (m3/h sewage).3) sewage Residence time;The residence time is about 0.5-1h to this equipment sewage in a device.Use the detailed process of this equipment clean sewage for: Sewage enters from water inlet, progressively flows to Disengagement zone, and electrolysis water produces hydrogen and oxygen, hydrogen and oxygen flow to Disengagement zone, passes through Microbubble nucleation is crossed, grows up and departs from so as to floating load impurities in water particle, the impurity particle for being coated to microbubble is slow by Disengagement zone Slow aggregation forms scum silica frost so as to bubble through the water column, and lower floor's clear water is discharged after flowing to gathering ground from delivery port;Scum silica frost is collected by collection flitch, Chain-driving scraper plate is moved back and forth, and the scum silica frost that scraper plate will accumulate on collection flitch is discharged after scraping scum pipe through scum pipe;So as to It is purified water.The air floatation wastewater treatment device of the structure, based on electrochemical techniques, microbubble is produced using by electric energy Air-float method, its caused bubble hydrogen particle diameter is 10~30um, not soluble in water, and its capacity is the 1/11200 of water capacity, and bubble is caught It is stronger than the ability of pressure floatation air, air-dissolving air-float to catch ability.Its averag density at 20 DEG C of bubble hydrogen grain caused by electrochemistry air supporting For 0.5g/L, much smaller than general atmospheric density, its floating loading capability is twice the above than pressure floatation air and air-dissolving air-float, therefore effectively Improve wastewater purification efficiency and effect.In addition, the application also has the following advantages that:
1) principle is advanced, high treating effect
The air-float method of microbubble is produced by being electrolysed, its caused bubble hydrogen particle diameter is 10~30um, not soluble in water, its Capacity is the 1/11200 of water capacity, and bubble capture ability is stronger than the ability of pressure floatation air, air-dissolving air-float.Electrochemistry air supporting produces Bubble hydrogen grain at 20 DEG C its averag density be 0.5g/L, much smaller than general atmospheric density, its floating loading capability compares pressure floatation air And air-dissolving air-float is twice the above.
2) gas production can be adjusted arbitrarily
Can by adjusting dc source output current, voltage parameter adjusts bubble diameter, number of bubbles, can be according to not going together Industry different quality situation is adjusted flexibly;
3) it is noiseless
Because its main gas generation module is dc source and aerogenesis battery lead plate, noise is small during its work, operation It is quiet;
4) equipment volume is small
Due to electric floating, it produces that microbubble its particle diameter is smaller, and surface area is bigger, and it is stronger to float loading capability, therefore needed for it The current residence time is smaller than other air-float technologies, therefore the volume of flotation tank can be smaller.Under normal circumstances, identical is handled The volume of flow flotation tank is about less than the 50% of other air flotation technology flotation tank volumes;Therefore its volume can be smaller.
Finally illustrate, above example is only unrestricted to illustrate the technical solution of the utility model, although ginseng The utility model is described in detail according to preferred embodiment, it will be understood by those within the art that, can be to this The technical scheme of utility model is modified or equivalent substitution, without departing from the objective and model of technical solutions of the utility model Enclose, it all should cover among right of the present utility model.
