Description
Technical Field
The utility model relates to a three-phase FeC reaction tower for high concentration coking wastewater treatment belongs to the waste water treatment equipment field.
Background
In the treatment of high-concentration coking wastewater, the key point is to break the benzene ring and the chromophoric substance of the benzene pollutants in the coking wastewater.
In recent years, FeC reaction tanks are adopted at home and abroad, and FeC reaction can efficiently break benzene rings and color development substances, so that the BOD/COD value in the coking wastewater is remarkably improved while the coking wastewater is decolorized, thereby providing a prerequisite for successfully treating the high-concentration coking wastewater.
However, the common FeC reaction tank for treating the coking wastewater has the defects of poor corrosion resistance (FeC reaction is carried out under an acidic condition and has an electrolytic corrosion effect), immersion reaction, limited reaction speed, viscous and easily precipitated coking wastewater reaction products, difficulty in timely removing precipitates, easiness in blocking and hardening of FeC fillers and difficulty in replacing the FeC fillers.
Therefore, in the coking wastewater treatment, the design of a common FeC reaction tank needs to be overturned, and a new FeC reactor is created.
SUMMERY OF THE UTILITY MODEL

In order to realize the purpose, the technical scheme of the utility model is that: the utility model provides a three-phase FeC reaction tower for high concentration coking wastewater treatment, includes the tower body, its characterized in that: the top of the tower body is provided with a spraying water distributor, the spraying water distributor is connected with a spraying water inlet, at least one layer of floating valve tower tray is arranged below the spraying water distributor in the tower body, FeC filler is arranged on the floating valve tower tray, an air inlet hole is arranged below the lowest layer of floating valve tower tray and is connected with an aeration fan, an air flow redistributor is further arranged on the air inlet hole, a gas discharge port and a liquid discharge pipe are respectively arranged at the top and the bottom of the tower body, and a dehydrator is arranged on the gas discharge port.
In the three-phase tower, coking wastewater is distributed by a spray water distributor under the action of a pump, turbulent flow is sprayed on FeC filler, gas-phase air rapidly impacts on the FeC filler from the tower bottom under the action of an aeration fan, three phases are subjected to turbulent flow violent reaction on a floating valve tray, benzene rings and chromophoric substances in the coking wastewater are broken under the double actions of micro-electrolysis of the FeC filler and oxidation of air, the BOD/COD value is obviously improved, and the wastewater descends layer by layer along with the floating valve tray while descending. After reaching the reaction depth, the reaction effluent flows out from the bottom of the tower.
In a common FeC reaction tank, wastewater flows through a FeC filler in a advection manner, and reaction products are easy to precipitate on the filler to block micropores of the filler, so that the filler is caked and hardened to lose effectiveness. The reaction tower has the functions of spraying and aerating, liquid-phase wastewater is sprayed on the solid-phase filler in a turbulent manner under the action of a pump pressure, gas-phase air rapidly impacts the solid-phase filler from the tower bottom under the action of an aeration fan, and reaction products cannot be precipitated on the filler under the impact of the three-phase turbulent flow, so that the filler is not easy to agglomerate and harden.
The common FeC reaction tank adopts an immersion reaction, and the reaction speed is limited.
This technical equipment does not adopt the reaction of soaking of pond formula, and adopts the spray column structure, and coking wastewater is under the pressure of pump, and the quick atomizing sprays on FeC packs, and the contact is more abundant, and under the effect of pump pressure and gravity, waste water descends along tower tray successive layer, and the limit descends the limit and reacts. The reaction speed and the reaction depth are improved.
In addition, the oxidation effect of aeration ensures that benzene rings and color development substances broken by FeC reaction in the coking wastewater can be oxidized in time, and reverse reaction is not easy to generate, so that the depth of FeC reaction can be maintained and enhanced.
Secondly, traditional FeC method is the tiling cell body, the utility model discloses three-phase FeC reaction tower is for erectting the tower body, with highly trading the area, so take up an area less than traditional FeC pond.
In the scheme, the method comprises the following steps: the dehydrator comprises a baffling dehydrator and a rotational flow dehydrator which are sequentially installed from bottom to top. The dehydrator is arranged, exhaust gas has two-stage dehydration function of cyclone dehydration after baffling dehydration, and waste water cannot leak to cause pollution.
In the scheme, the method comprises the following steps: the spraying water distributor adopts a gull wing-shaped wire winding pipe water distributor. The water distributor configured by the device completely abandons the design of the traditional water distributor and adopts a gull-wing-shaped filament winding pipe structure (the cross section of the filament is gull-wing-shaped). The gull wing shape has a bionic cross-sectional structure similar to a gull wing, has the characteristic of small fluid resistance, is more favorable for the flow of water, and ensures that the pressure drop of the water is small, thereby greatly reducing the energy consumption of the water pump.
In the scheme, the method comprises the following steps: the spraying water distributor is made of titanium alloy. The equipment adopts an innovative titanium alloy water distributor, and has high material strength and corrosion resistance.
In the scheme, the method comprises the following steps: the spraying water distributor is arranged in the tower body through an elastic damper. The structural mechanics redesign is adopted, and the elastic damper with elastic damping is adopted to discharge the water pressure reaction force applied to the water distributor, so that the water distributor is not easy to fatigue failure. The problem of easy tired of equipment internals has been solved.
In the scheme, the method comprises the following steps: and a liquid redistributor for avoiding water wall flow is arranged above each stage of floating valve tray. The adoption of the float valve tray redistributor prevents the wall flow and short circuit of the wastewater, so that the wastewater at each point can be fully treated.
In the scheme, the method comprises the following steps: the lower part of the liquid discharge pipe is bent into a U shape to form a water seal structure.
In the scheme, the method comprises the following steps: and automatic discharge manholes are arranged on the tower body corresponding to each stage of float valve tower plate and the spray water distributor. In a common FeC reaction tank, FeC filler is laid at the bottom of the tank, a large amount of cleaning work is needed for replacing the filler, and the working environment is severe during cleaning.
The utility model discloses when unloading, can open the shower water, spray + discharge opening, solved the problem that FeC packs and is difficult to change. When the filler is unloaded, the filler can be automatically flushed and unloaded out of the tower body by pressure water only by opening the discharge hole and opening the spray pipe.
In the scheme, the method comprises the following steps: the tower body is filled with low-calcium magnesium rubber. Because the low-calcium magnesium rubber is not acid-resistant and non-conductive, and the low-calcium magnesium rubber is lined, the corrosion prevention problem of FeC reaction is solved, and the technical equipment can stably run for a long time in an acid environment and an electrolysis environment.
Has the advantages that: the utility model discloses a three-phase FeC reaction tower for high concentration coking wastewater treatment, reasonable in design, area is little, packs and does not agglomerate, and reaction efficiency is high, and the treatment effect is good, and equipment is anticorrosive, the durability is strong.
