Abstract

The PRESIDENT, wet filter using liquid (water in which some chemicals are added) as filtrate, cleans dirty gasses by removing dust and eliminates dangerous gasses. This affect is achieved due to simulation of rain behavior in the nature, but here in a small space. For that purpose through the pipe (22) the dirty mix of gasses is forced through the nozzle (3) reaching the speed of 200 km/h on the waterfall (4) what courses splitting of liquid which is taken from the container (21) through the pipe (5), forming a homogeneous mixture of: ions, molecules, small droplets and dust. At that place the physicochemical processes occur coursing that on the deflector (8) and nozzle (29) the particles of liquid are separated from gas. In this way it is achieved that dirty gas having 5-10000 mg/m3 of dust is getting out clean with les then 0.05 mg/m3. Adding in the water chemicals which absorb destructive gasses (e.g. SO2) the gas mixture containing 2930 mg/nri3 of SO₂ eliminates SO₂ completely which due chemical process is converted to solid particles, which are ecologically neutral, and which remain in the filter with dust.

Claims

AMENDED CLAIMS received by the International Bureau on 30 December 2009 (30.12.2009)(Original claims 1 to 5 replaced by AMANDMANT CLAIMS 1 to 5)PATENT APPLICATION

1. The basic cell of Industrial Wet Filter (MIF) (Figs. 11 and 12) has: container {Fig. 11, , Ref.. 1) contains filtrate (liquid) and connects all other filter parts, input tube (Fig, 11, , Ref.. 2) used that under pressure or due to the vacuum introduces the dirty gas, and this tube is on the bottom part horizontally connected to the nozzle (Figs.l 1 and 12, Ref.. 3), then it has, indicating by that, side depth tubes (Figs. 11 and 12, , Ref... 5) which are used to increase resistance to liquid flow by height difference and regulate liquid intake to the waterfall (Figs.l 1 and 12 Ref ,4) in the ratio of 5 to 15 liters toward 1000 liters of gas, this liquid is by gas energy, which coming from the nozzle (Figs. 1 1 and 12 ReO), is sprayed down to small droplets, molecules and ions creating phisic- ohemical condition and providing in such a way gas cleaning process, reactor (Figs.l 1 i 12 , Ref..7) whose horizontal length could be between of 3 D to 12 D (D being diameter of reactor tube) with slight arc of 90° is transferred into vertical part of the lengthy of 2 D to 5 D, output reactor hole (Figs. 11 and 12, Ref..7) is its top point and it is dived into liquid, placing deflector with its holders whose lengthy is 1,5 (Fig. 11, , Ref.. 8) so that its center is on the distance of D to 3D above of output hole of reactor (Fig.11, , Ref..7.), with the holder of the length Of 1 ,5D to 3D which is fixed to the lid (Fig. 11, , Ref., 11), on the deflector (Fig. 11 , Ref.. 8) incomplete separation of gas and liquid is achieved and because of that the nozzle (Fig, 11, , Ref,,9) is inserted to use joint kinetic and gravitational energy to direct remaining droplets and particles in the gas towards downwards to the liquid, while the clean gas is directed upward to outlet (Fig.l 1, , Ref..12) which are on the lid (Fig.1 1 , Ref..1 1 ) in order that the nozzle performs good cleaning it is necessary to place the barrier consisting of lower (Fig, 11 Ref, 6a) and upper (Fig.l 1 , Ref. 6b) part of the barrier dividing container (1) into two chambers (I and II), lower side of the lower part of the barrier (Fig.l 1, Ref. 6a) is dived into liquid in order to prevent gas flow through the liquid through the bottom part between chambers, while the regulation of liquid level is done according to the law of connected vssels; bottm (Fig.l 1, Ref. 6a) and upper (Fig.l 1, Ref. 6b) part of barrier on the mutual connection is processed in such a way to form the linear nozzle (Fig.1 1 , Ref. 9).

2, MIF filter with more branches. As an example of the filter with with more branches the cell with four branches (Figs, 13 and 14) is considered. This cell, indicated as that, possesses a vessel (Fig. 13, Ref. 21) in which all parts of filter are situated and which contains filtrate (liquid performing gas cleaning) , input tube (Fig. 13, Ref. 22) at which at the bottom part under angle of 90° equally spaced concentric four branches (Fig.14) are placed and each having a nozzle (Fig. 11, Ref. 3) depth tube (Fig.13, ReO), waterfall (Fig. 13, Ref. 4), reactor (Fig.13, Ref. 7) and above all four branches deflectors with holders (Fig. 13, Ref. S) are placed having centers on a distances of ID to 3D above the center of output reactor holes (Fig. 13, Ref. 7) and with the holders of the length 1,5D to3D are fixed to the lid (Fig. 13_} Ref.31 ), barrier consisting of bottom part (Fig, 13, Ref. 26a) and upper part (Fig.13, Ref, 26b) which are cylindrical parts so that vessel (Fig, 13, Ref. 21) is divided into two chambers: outer chamber (I) and inner chamber (II), lower part of a cylindrical barrier (Fig. 13, Ref. 26a) is dived in a liquid to prevent of gas to flow through the liquid between inner chamber (11) and outer chamber (I) , but the liquid level control is maintained on the principle of connected vessels, lower part (Fig.13, Ref,26a) and upper part (Fig. 13, Ref. 26b) on the mutual connection are processed in such a way to form a linear nozzle (Fig.13, Ref. 29) (so that essentially along the whole mutual connections a nozzle is formed) which is used so that the joint kinetic and gravitational energy is used to force eventually remained particles and small droplets in the chamber (I) into liquid in chamber (H) and cleaned gas forces upward to output tube (Fig, 13, Ref. 30) placed on the lid (Fig.13, Ref. 31). , Filter MIF with more cells, branches and chambers. Filter MIF could be used for cleaning of dirty gases with the flow rate from a couple of liters to a couple thousand of liters per second and could have different number of cells, branches and chambers, here, as an example, only design with cell having two branches and more chamber is considered (Figs, 15 and 16) which, indicated as that, has a huge vessel (Fig, 15, Ref, 41) connecting all the filter parts and containing filtrate, main input tube (Fig, 16, Ref. 52) used to introduce a dirty gas, then collector (Fig. 16, Ref. 53) from which by means of distributing tubes (Fig. 16, Ref. 54) gas is sent to all input cell tubes and from them to all branches of filter (with the contents and functionality described above), barriers (Fig.15, Refs. 46a and 46b) dividing vessel, in this case, into 5 chambers I, II, IE, IV and V (Fig. 15 and 16), in 3 chambers (1, ITI and V) are placed parts of the filter branch and process of gas cleaning is performed there, two chambers (II and IV) are used to distribute the dirty gas from input tube(Fig. 16, Ref. 52) through collector (Fig. 16, Ref, 53) and the through tubes (Fig.16, Ref. 54)to all input tubes of cells (Fig. 13, Ref. 22), each barrier consist of two parts; lower part (Fig, 15, Ref. 46a) and upper part (Fig. 15, Ref, 46b), lower part of the barrier is dived into liquid to prevent of gas flow through the liquid between chambers and level of liquid between chambers is control on the principle of connected vessels,, lower part (Fig. 15, Ref.46a) and upper part (Fig. 15, Ref. 46b) of a barrier on the mutual connections is processed to form a linear nozzle (Fog, 15, Ref.49) used that the joint kinetic and gravitational energy force the particles and droplets which are in chambers I₃ III and V downwards in the liquid in chambers I and IV and clean gas upward towards output t to outlet collector (Fig.15, Ref.55) and then towards main output tube (Fig. 15, Ref. 56) and to atmosphere. , Vacuum cleaner (Fig, 17), indicated as that, consists of a filter with basic cell, or with a basic cell with more branches, dust collection from the floor is performed via standard vacuum cleaner auxiliaries under influence of turbine which courses the pressure differences forcing air flow through tube into the filter, for the additional cleaning of air from carcinogen carbon dust produced due to wear away of carbon brushes of a vacuum cleaner electromotor must have a tube (or a chamber) (Fig, 17, Ref. 16) through which electromotor fan (Fig. 17, Ref, 16) is supplied by air used for cooling of electromotor since electromotor housing (Fig.17, Ref. 17), on the bottom part posses one or more holes (Fig.7, Ref. 18) which are hermetically connected with tubes (Fig.17, Ref.19) with the input tube (Fig.17, Ref,2), and filter operates as described above. , For the application in thermo power plants besides MIF filter (3) there must exist also: cooler (2) , consumer of thermal energy (8), precipitator (4), waste collection device (7), and a container for regeneration and preparation of filtrate (filtering solution)
