Abstract
The present invention is a kind of gas blasting type electro-hydraulic impulse device that is used for Industrial Wastewater Treatment.The present invention utilizes electro-hydraulic impulse technology, and an electrode that makes wastewater treatment equipment is a nozzle, and feeding another electrode of pressurized air is a flat board.Point---when plate discharges in waste water, make the energy abrupt release that is stored in the electrical condenser, make each component in the waste water that disassociation take place or reconfigure and reach the decontamination purpose, it is little that the present invention invests, and takes up an area of few, working cost is low, technology is simple, is easy to automatization, and dirty removal capacities is strong, be not subjected to the influence of waste water acid, alkali, electroconductibility, can be used for printing and dyeing, the processing of trade effluent such as leather, papermaking, food.
Description
The present invention is a kind of high voltage device that utilizes electro-hydraulic impulse technology to handle various industrial sewage.It is quick-fried to be characterized in adopting air-flow to lead, and facilitates discharge in water, and the energy that is stored in the electrical condenser discharges, and forms low-temperature plasma, makes each component in the waste water take place to dissociate or reconfigure, and reaches the purpose of decontamination.
Mainly adopting chemical method, biochemical process, electrochemical process or the like aspect the processing trade effluent both at home and abroad at present.The shortcoming of the employed device of these methods is that investment cost height, floor space are big, the working cost height.And they still can not handle the trade effluent as waste water from dyestuff and so on.Utilize electro-hydraulic impulse technology to handle trade effluent, though once carried out big quantity research in the Soviet Union, but because of the influence that is subjected to the waste water conductivity is very big, thus do not succeeding as yet so far aspect the trade effluent extensive the processing, and be confined to be used on the packaged unit of killing intestinal bacteria etc.
The present invention has adopted the high pressure gas jet to lead quick-fried and new electrode connecting mode on the basis of adopting electro-hydraulic impulse technology, thereby electro-hydraulic impulse technology is become a reality to the extensive enforcement of trade effluent scrubbing, because investment cost of the present invention is low, energy consumption is little, floor space is little, technology is simple, is easy to large-scale promotion, can be reached for country and economize on the use of funds, save floor occupying area, save energy reduces environmental pollution, the purpose of keeping ecological balance.
Processing trade effluent device described in the invention is made up of impulse current generator 1 and waste water reaction chamber 6 two portions, as accompanying drawing 1.Impulse current generator is made up of high-tension transformer 2, high voltage silicon rectifier stack 3, electrical condenser 4, air switch 5.The waste water reaction chamber then is made up of electrode 7 and working chamber 8, and positive electricity is a nozzle very, and pressurized air nozzle is thus introduced, and negative electricity is a flat board very.Positive electrode ground connection when whole device work, forms point-plate discharge in the waste water reaction chamber.
Principle of work of the present invention is, when whole device work, air switch is by electrical breakdown, and the main gap in the working chamber is also breakdown thereupon, thereby with the energy (W=0.5CV that stores in the electrical condenser
2C is a capacitance, V is a sparking voltage) instantaneous (10～100 microsecond) discharge, in liquid, form plasma channel, its temperature reaches 7000～30000 ° of K, in plasma channel, discharge channel is with cavity form rapid expansion with its energy storage for superheated ionization of gas and steam, and its speed of expansion can surpass the velocity of sound of this liquid.Under the internal pressure effect, incompressible medium (waste water) is on every side produced wave of compression and surge pressure.When the energy in the passage discharged in a large number, wave of compression was transformed into shockwave.The expansion of cavity just stops when lasting till the interior pressure of cavity less than ambient pressure always.At this moment, because inertia effect generation liquid stream is closed, the reversing motion of liquid stream sharply increases the interior gaseous tension of liquid once more.This process increases decay gradually in time.When above-mentioned phenomenon took place, the air of introducing was dissociated, and produced positive aeroion, negative aeroion, ozone, oxonium ion etc.Each component in the waste water high temperature, high pressure (500～1500MPa), the combined action of highfield, high-intensity magnetic field, intensive ultraviolet, pulsed pressure wave, cavitation effect and free radical of being produced etc. issues and estrangedly separates or reconfigure, and makes the waste water decontamination.
The present invention compares with existing wastewater treatment equipment, and its advantage is: floor space is very little, even handle thousands of tons of every day, also only needs tens of square metres; Investment cost is low; Working cost is low; Technology is simple; Easy to operate, easily be automated; The scrubbing effect is strong; Treatment capacity can change on demand flexibly; Be not subjected to the influence of waste water acid, alkali, electroconductibility etc.
The present invention is particularly suitable for removing COD, the BOD in the waste water.The present invention can be used for dyestuff, the processing of trade effluent such as printing and dyeing, leather, papermaking, food and medical waste water and sanitary wastewater.(its COD is that 3000～5000mg/l) clearances reach more than 80% to waste water from dyestuff after the present invention handles.
