Description

METHOD AND DEVICE FOR
ELECTROCHEMICAL - PLASMA PURIFICATION OF FLUE GASES
FIELD OF APPLICATION
The invention relates to purification of flue gases from various boiler installations, for achieving acceptable environmental conditions.
BACKGROUND OF THE INVENTION
Technology is known for complex gas cleaning, described in Euro-Asian patent 005264, published on 30.12.2004. This technology is designed for recovery cleaning of flue gases from harmful oxides and is based on the principles of plasma gas electrochemistry, namely on the fact that the gas flows pass through zone with electrons, running out of needle cathode and directed towards anode. The electrons with sufficient energy excite and break up the molecules of harmful gas components and the contained in the gas flow water vapor into ions and radicals, as a result the contained in gases oxides of sulfur, carbon and nitrogen recover, the molecular nitrogen formed leaves the reactor together with the outgoing purified gases, sulfur and carbon recover to neutral elements, fall on the anode and are taken out with the running water layer. The reactor, in which these processes take place, has a reaction zone formed between two frustums of cones, inverted vertically with their bases up. Inside the larger cone the smaller one is inserted, which is a needle cathode and the external cone performs the function of anode on the inner surface of which water layer flows. The processed gases pass through the reaction zone formed between the offset in height cones, where they are treated with the electron flow.
Invention EA0052266/B1 from 26.01.2004 is known, which differs from the above described only in that it explains the action of the atomic hydrogen required for the recovery chemical process. Invention ΕΪΪ200800310/Α1/ from 29.12.2007 describes a method for flue gas cleaning from harmful components, this invention is not substantially different from the previous two inventions. The difference is in the device for implementation of the method only, which is a vertically positioned cylinder in shape. Patent application B 110813/A/ is known, the flue gas cleaning from harmful components in it is based on chemical processes only without the involvement of electronic radiation.
In the description to invention EP0697235A1 from 16.08.1995 the options are set up for feeding ammonia solely, applicable for the realization of oxidative processes only; the flow is directed towards the flue gas in part of the reaction chamber only. The electron flow is probably from electron gun, as there is no mention of the presence of cathode and anode, necessary for the formation of electric field. The technology is implemented in dry volume, therefore dust-catchers are provided for collecting the compounds formed.
SUMMARY OF THE INVENTION
This invention relates to a method for electrochemical - plasma purification of flue gases from oxide impurity gases, the flue gases move horizontally in cathode-anode reaction zone, in direction opposite to the movement of horizontal water flow, which is the water anode. Upon high voltage application from the upper cathode surface of the reaction zone electrons are emitted; when moving perpendicularly to the gas flow and the aqueous anode flow they ionize the molecules of gases and the water vapor in them. The products of the electrochemical reactions taking place fall into the flowing water layer, which takes them out of the reaction zone.
By the electrochemical supply of the cathode flue gas oxidative cleaning is also implemented, as conditions are created in the water layer for the oxidation of sulfur dioxide, carbon dioxide and nitrogen oxides. An acidic mixture is formed in the water, to which after its exit from the reaction zone ammonia or sodium hydroxide is added. In that way a complex product is obtained, containing sodium nitrate, nitrogen nitrate, ammonium sulfate and ammonium carbonate.
The ammonia and the solution of sodium hydroxide may be also fed directly into the reaction zone. By subsequent crystallization outside the reactor a solid product is obtained. The complex product obtained in the reaction zone or outside it, containing sodium nitrate, nitrogen nitrate, ammonium sulfate and ammonium carbonate, can find application in plant growing as fertilizer.
The transformations of the molecules of harmful gases and the water vapor contained in flue gases into excited molecules, electrified radicals and atoms, ions and recovered elements take place between the needle cathode, placed horizontally and the horizontal water flow /anode/; the flue gases move between them in direction opposite to the water flow movement. The horizontal or nearly horizontal water flow allows varying its thickness and quiet motion, which eliminates any possibility of throwing out water drops and splashes in the reaction space, leading to undesirable spark formations and short circuits. Furthermore, the greater thickness of the flow creates a higher volume capacity for the products of the electrochemical reactions taking place, resulting in the opportunity for passing higher volumes of flue gases, even with high concentration of harmful impurities.
A device for purification of flue gases, according to the method, comprising a horizontal reaction chamber 1. The upper side of the chamber is a needle cathode 3 and over the lower side water flows, acting as an anode. The thickness of the water flow changes by means of sliding mode regulator. The water enters the reaction chamber through the ascending pipe 2. On the same side of the chamber the outlet 9 for purified gases is situated. On the opposite side of the chamber a gas distribution grid is formed 7 with openings. The flue gases are fed through inlet pipe 5 in a hollow inclined prism 6, mounted in front of the gas distribution grid; the hollow inclined prism is connected with sliding mode regulator of level 4 on the other side with work plate for regulating the water flow.
Such devices can easily be produced with different volume capacity of gases, simply by making them with different length and width for providing the desired volume of the reaction zone. For gases, creating deposits of reaction products on the edges of cathode needles, these products can be easily removed by making perforations on the bottom of the high voltage zone, through them parallelly to the needles compressed air streams are fed, pulling down the accumulations on the needles. Depending on the electric power supply scheme of the cathode /constant, impulse or mixed voltage/ the oxidative cleaning of flue gases is also possible.
With the present invention the following technological difficulties are eliminated:
the difficulties in manufacturing the cones and the installation of the numerous needles on conic or cylindrical surface;
the formation of reaction zone between the two vertically inverted cones, which forces the water layer, running on the solid surface of the cone, to remain relatively thin in order rough water motion to be avoided, when water drops and splashes can be formed, causing electrical short circuits;
the formation of reaction zone between the vertically inverted cones also leads to progressive thickening of the water layer from above downwards, which is also accompanied by possible water wave formations with effects electrical short circuits; the thin water layer makes it necessary to work with relatively low productivity due to the rapid saturation with reaction products.
AN EXAMPLARY EMBODIMENT OF THE PROPOSED DEVICE IS SHOWN IN THE FIGURE ATTACHED
With the following positions:
1 - Horizontal reaction chamber
2 - Entrance of water
3 - Needle cathode
4 - Sliding mode regulator of level
5 - Flue gas inlet
6 - Hollow inclined prism
7 - Gas distribution grid
8 - Water level
9 - Outlet of cleansed flue gases
The inlet flue gas flow is fed through feed chamber onto perforated distribution plate, which distributes it evenly on the section of the reaction zone formed between the surface of the water flow and the needle cathode, situated in the bottom of high voltage zone. The opposite movement of the gas flow and the water has the advantage that the gases initially move over the water, already saturated with products of the reaction processes and at the end - over the water with low concentration of such products, which helps the quick seizure of these products by water, where they are dispersed in its volume. As shown, the thickness of the water flow can be varied depending on the concentration of harmful gas impurities, for this purpose a sliding mode regulator is used, whose work plate can be varied in height.
