The total chloride ions of the circulating cooling water and the desulfurization waste liquid of the power plant are the most stable form of chlorine, and the chlorine in the industrial waste water exists in the form of chloride ions.

The electrochemical method has high efficiency for treating chlorine-containing wastewater, stable effect, difficult blockage and higher chloride ion removal rate, and is particularly more advantageous for wastewater with higher chlorine concentration, thereby having better prospect. However, the traditional two-dimensional electrode direct current electrolytic method has high running cost, poor capability of treating low-concentration chlorine-containing wastewater, and generates chlorine in the treatment process, and technical optimization and a tail gas treatment system are needed.

The technical scheme of the present utility model is described below with reference to fig. 1.
As shown in FIG. 1, the device and the system for removing high-concentration chloride ions are characterized in that: the device comprises a direct current pulse power supply, a three-dimensional pulse electrolytic cell, a spray tower and an air compressor; the three-dimensional pulse electrolytic cell is composed of a positive plate, a negative plate, a three-dimensional electrode and an aeration tube, and an air outlet of the three-dimensional pulse electrolytic cell is connected with the spray tower.
Further, the direct current pulse power supply is a low-voltage direct current high-power pulse power supply, the output voltage of the direct current pulse power supply is less than or equal to 30Vdc, and the power is 3-100kW.
Further, the positive plate and the negative plate in the three-dimensional pulse electrolytic cell are made of graphite, stainless steel and metallic titanium electrodes.
Further, the three-dimensional electrode is made of activated carbon particles.
Further, the three-dimensional electrode is made of activated carbon particles.
The three-dimensional electrode structure adopted by the system is a three-dimensional electrode rectangular electrolytic tank, the main electrode plate is a graphite electrode with the same quality as that of a cathode electrode and an anode electrode, and the three-dimensional electrode filler is activated carbon particles. The graphite electrode basically does not participate in the reaction when being electrified, is low in cost and easy to obtain, has good chemical properties, can reliably conduct current, the current is uniformly distributed on the surface of the electrode, and the high electrostatic field between the two electrodes can enable active carbon particles to become third electrodes due to electrostatic induction to participate in the electrocatalytic oxidation reaction, and meanwhile, has enough corrosion resistance and can be used for a long time. Compared with the traditional two-dimensional planar electrolytic electrode, the three-dimensional electrode system has the advantages of high reaction speed, low energy consumption and better treatment effect under the same conditions of the three-dimensional electrode structure.
The electrochemical reaction in the three-dimensional electrode is a dynamic uninterrupted adsorption, electrolysis and desorption process, the adsorption saturated activated carbon is selected as a three-dimensional particle electrode for example, the adsorption capacity is strong, the surface area ratio is large, the two ends of the activated carbon particles are respectively provided with positive and negative charges under the action of an external electric field due to the electrostatic induction effect, an independent micro-electric field is formed around each carbon particle, organic pollutants in the wastewater are adsorbed and deposited on the particle electrode to perform electrochemical oxidation and reduction reactions, the pollutants are desorbed from the carbon particles after being decomposed, the pollutants which are not decomposed are adsorbed on the desorbed carbon particles, so that the continuous cyclic adsorption-degradation reaction on the carbon particles is carried out, the pollutants in the wastewater are continuously degraded, and the pollution treatment effect is achieved. The lower limit of the concentration of chloride ions treated is therefore further reduced compared to the direct current electrolysis of conventional two-dimensional plates.
When the solution contains Cl-, the following reactions can occur during electrolysis:
2Cl - →Cl 2 ↑+2e
Cl 2 +H 2 O→HOCl+Cl - +H +
HOCl→OCl - +H +
2H + +2e→H 2 ↑
cl generated in three-dimensional electrolysis process 2 OCl-HOCl has strong oxidability, and the strong oxidability can carry out oxidation reaction on other pollutants in water such as COD, ammonia nitrogen and the like, so that the concentration of chloride ions is reduced, and meanwhile, other pollutants are removed.
Shen Zhemin and the like also compare the effect of treating dye wastewater by the ACF three-dimensional electrode method and the Fenton reagent method, and researches show that the decolorization rate and TOC removal rate of the ACF three-dimensional electrode method on various dyes are obviously better than those of the Fenton reagent method.
The pulse power supply pulse three-dimensional electrolysis technology is used for treating electric field circulating cooling water and desulfurization slurry, CODcr and ammonia nitrogen removal rates can be respectively 67.2% and 76.7%, and compared with direct current power supply, the removal rates are respectively improved by 21.7% and 33.4%.
Further, the aeration pipe is immersed in the three-dimensional electrolytic cell, an air flow dissipation hole is formed in the aeration pipe, and the aeration pipe is further connected with the air compressor.
Further, the absorption liquid selected by the spray tower is NaOH solution or FeCl2 solution.
Further, the spray tower packing can be plastic or ceramic packing.
In the process of treating circulating cooling water and desulfurization waste liquid of a power plant by pulse three-dimensional electrolysis, chlorine gas is generated. Chlorine is a toxic gas, has strong pungent smell, can cause serious pollution to the environment, and can injure nearby staff. Therefore, when the pulse three-dimensional electrolysis technology is used, the electrolysis tail gas must be treated. When the tail gas containing chlorine is treated, an alkali liquor neutralization method or an ferric chloride absorption method is generally adopted, and the two methods can change waste into valuable and do not produce secondary pollution.
When the absorption liquid adopted by the spray tower is alkaline absorption liquid, namely the alkaline absorption liquid is adopted to absorb chlorine generated in the electrolysis process of the three-dimensional electrolytic cell by adopting an alkaline solution neutralization method, the alkaline solution is used as the absorption liquid to absorb the chlorine, and common absorbents are NaOH solution, na2CO3 solution, lime emulsion solution and the like. The sodium hypochlorite obtained by the method can be sold as a commodity, so that the aim of changing waste into valuables is fulfilled. The absorption rate of the chlorine gas can reach 99.9% by adopting a spray tower or a packed tower in the absorption equipment department, and the effect is very good. The chlorine content of the outlet after absorption can be lower than 10mL/m 3 。
When the absorption liquid adopted by the spray tower is ferrous chloride solution, ferrous chloride is used as an absorbent, and the chlorine is recovered and purified according to oxidation-reduction reactivity. The process equipment can adopt a packing tower, waste iron scraps are used as packing, the generated FeCl2 can further generate polymeric ferric chloride, the polymeric ferric chloride can be used as a high-efficiency water treatment flocculant, and ferric iron can be reduced by the iron scraps to participate in absorption reaction again. The method has the advantages of simple equipment, easy operation, abundant sources of waste iron scraps and reasonable technology.
Further, in the exhaust pipe of the electrolysis waste gas, chlorine, oxygen and hydrogen concentration sensors are installed, and at the same time, a chlorine concentration sensor is installed at the exhaust gas discharge port of the spray tower.
In the pulse three-dimensional electrolysis system, the control system mainly detects the concentration of chlorine ions on line in the wastewater, judges the concentration of the chlorine ions, determines whether to start the electrolysis system or not, and adjusts the parameters of the pulse power supply. Thus, not only the automation level of the system is realized, but also the energy saving purpose is achieved. Compared with a three-dimensional electrolysis system powered by a direct-current power supply, the three-dimensional electrolysis system adopting a pulse power supply for treating circulating cooling water and desulfurization waste liquid of a power plant has the advantage that the energy consumption is greatly reduced. The experimental results show that: under the optimal experimental condition, the energy consumption per unit mass of chloride ions powered by a pulse power supply is 80% lower than that powered by a direct current power supply.
In the exhaust pipeline of the electrolysis waste gas, chlorine, hydrogen and oxygen concentration sensors are arranged, when the system works, concentration parameters of the chlorine and oxygen sensors are referenced, whether the three-dimensional electrolysis system of the vein worm at the front stage works normally is judged, and meanwhile, the concentration of the hydrogen is ensured to be far smaller than a set value (for example, 1/4LEL and 1/4 of the lower limit of the explosion limit), so that the system is ensured not to explode and is in a safe state.
And a chlorine concentration sensor is arranged at the tail gas exhaust port of the spray tower and used for judging and prompting whether the tail gas absorption system operates normally.

The control system automatically determines the switch of the system by measuring the concentration of chloride ions in water, adjusts the voltage (current) and pulse parameters of the system, and ensures the treatment effect, the energy-saving effect and the safe operation of the system. Compared with the traditional two-dimensional planar electrolytic electrode, the three-dimensional electrode system has the advantages of high reaction speed, low energy consumption and better treatment effect under the same conditions of the three-dimensional electrode structure.
