Abstract

The system for energy saving, the purification of polluted air and fumes and the enrichment of air with ozone solves the problem of energy saving and eliminates pollution. This system consists of five elements: A) heater with convectors, element B) heat accumulator, element C) fume regenerating equipment, element D) fume purifier, element E) final purifier and of two ancillary equipments: element X) static suction fan, element Y) rotating suction fan. These elements can work independently of each other or together within the same system or in minor systems. If we use all these elements at the same time, we shall then have an ecological heater. If we use the system leaving out element A and element B, adding element X or element Y, we shall then have a purifying system for polluted air. The principle of this invention is that fumes or polluted air go to the atmosphere after being totally purified and enriched with ozone with the result of an enormous energy saving. The system can be used as a purifier for radioactive air after an accident occurs at a nuclear power station.

Description

SYSTEM FOR TREATING FUMES OR POLLUTED AIR

The present invention concerns the systems to solve the technical problems of energy saving, the purification of polluted air and fumes and the enrichment of air with ozone.

This invention is related to ecology.

In the technical field covering the present invention there are furnaces which pollute the environment to nearly the same extent.

There are no special internal-combustion engines working without polluting the environment.

At present there are no purifying systems capable of purifying the radioactive atmosphere, after an accident occurs at a nuclear power station, preventing therefore radioactivity to expand to most of the surrounding areas.

The heaters manufactured up to now are not equipped with flame and fume scroll convectors, ionizers and indirect convectors. The equipments known so far do not clean the air completely, do not include purifiers for fumes and polluted air, ionizers and infrasonic wave devices, do not use metal wool and are not suitable for radioactivity.

The present invention concerns an energy saving heater, which does not pollute the environment, and a purifying system to clean polluted air and enrich the air with ozone.

Such target has been attained by adding flame and fume convectors, ionizers, infrasonic wave devices, mist producing equipments, metal wool and circular and return convectors.

The present invention consists of 5 elements:

Element A - heater with convectors

Element B - heat accumulator

Element C - fume and gas regenerating equipment

Element D - fume and gas purifier

Element E - air cleaner

Each of the above elements can work independently of the others or they can work together within the same system or in ancillary systems.

They can work as a heater, as a heat accumulator, as an air-conditioning unit, as an air humidifier or as an air cleaner. There are two ancillary suction units: element X - static element - and element Y - rotating element. These elements can be placed ahead of the system, if the latter is used as a purifier.

According to the basic principle of the present invention, the fumes and gas flow into the atmosphere after being totally purified and enriched with ozone.

If all the above elements (A,B,C,D,E) work' at the same time within the same system, we shall then have an ecologically clean furnace.

If we leave out element A, the system can be applied to any kind of chimney and can be used in heating plants.

If we leave out elements A and B and place elements X and Y ahead of element C, the system can be used in industrial plants, indoor in a highly polluted environment, as well as in nuclear power stations, where in case of accident the radioactivity could produce harmful effects to the surrounding atmosphere.

Element E is the only one that can be applied to internal-combustion engines by adding it to the exhaust pipe. Elements D and E can be used in a highly polluted environment and built-up areas, after placing elements X and Y ahead of element D, or installing a main chimney connected to the other chimneys. The system combining the elements for energy saving, the purification of air and fumes and the enrichment of air with ozone is a multipurpose system, therefore it can be manufactured in different sizes. Thanks to that system we can purify both fumes and air completely, regardless of the degree of pollution.

The present invention shall be illustrated in vertical sections with examples by means of drawings and legends.

I. STRUCTURE OF EACH ELEMENT

1. ELEMENT A - Heater with convectors - Figure 1

This element is the heater. It differs from the heaters known sto far in the fact that in the main scroll convectors (A/18) of the boiler (A/1) there is a spiral flame convector (A/16), fixed by means of supports (A/22a) above the main scroll convector (A/18). If we use liquid fuel, the tip of the flame convector shall be turned upwards and if we use solid fuel, the tip shall be turned downwards. The supports are placed in hallows (A/23a). The new elements are the fume scroll convectors (A/15). While the flame convector is suspended over the main scroll convector (A/18), the fume convectors are suspended over the side scroll convectors (A/17). A flue (A/12) is welded outside to the main structure below the grate for solid fuel (A/7) at the bottom of the structure (A/24). This flue ends up in an opening (A/26) on top. At the basis there is non-return valve with support. The opening (A/26) leads into a square tube (A/25) ending in a pyramid at the bottom. The ionizers (A/14) are fastened in this tube by means of supports. At the top of the flue there is a fan (A/13). The ionizers (A/14) and the fan (A/13) are controlled by a control unit. The flue (A/19) is equipped with a fume conveying device (A/20). If element A works in a system including element D, the fan (A/13) and the ionizers (A/14) shall be controlled by control unit D/39. If it works with element C, without element D, the fan (A/13) and the ionizers shall be controlled by control unit C/27.

2. Element B - Heat Accumulator - Figure 2

The heat accumulator is made up of an insulated (B/2) double-walled metal structure (B/1). Inside element B there is a metal mass (B/10) which constitutes an excellent heat conductor. In the upper part of element B there is an opening to let the pipe (B/3) in. A flue (B/4) crosses the metal mass (B/10) and is connected to opening B/3. It is a good heat conductor, resistant to H2SO4 and smooth inside. The flue (B/4) goes down across element B, then it goes out of it at the bottom and continues in the electromotor housing (B/5). At the bottom of element B there is a water pipe (B/11) which connects to element B through opening B/7 and crosses the flue (B/4) leaving element B through the water outlet (B/8). The electromotor housing consists a four-way pipe (B/5a, B/5b, B/5c, B/5d). The first way (B/5a) connects to the flue (B/4), the second one (B/5b) to the mist collecting chamber (B/13), which has an opening leading to the lower mist collecting chamber (B/14). Between the upper mist collecting chamber (B/13) and the lower mist collecting chamber (B/14) there is a timer-controlled electromagnetic valve (B/6). The third way (B/5c) connects to the two-speed electromotor (B/9), the fourth way (B/5d) connects to flue B/15. Inside the electromotor housing (B/5) there is a suction fan operated by the power supplied two-speed electromotor (B/9).

Along the flue there is a sensor (B/16) controlled by control unit D/39, if element B works with element D. If element B works without element D, the sensor can be left out.

If element B works with element D the electromagnetic valve (B/6), the two-speed electromotor (B/9) and the sensor (B/16) shall be controlled by control unit D/39. If we leave out element D and include element C, the timer-controlled electromagnetic valve (B/6) and the electromotor shall be controlled by control unit C/27.

3. Element C - Fume Regenerating Equipment

This element regenerates fumes and works both as a a cooling system and as a mist collecting system. It is made up of a metal structure (C/1), smooth inside and resistant to H2SO4. The outer wall is insulated and both the upper and lower end are cone-shaped. The upper cone is a removable cover (C/2), the lower cone is the cylinder bottom. The structure (C/1) is based on feet (C/29). The cover (C/2) and the bottom (C/14) can be removed from the cylinder (C/1a) since they are applied by means of flexible rings (C/3a and C/3b). At the top of the removable cover (C/2) there is an opening connecting to flue C/30. Inside element C and just below flexible ring C/3a there is a conveying cone (C/10) fastened with screws and suspended inside element C, thus leaving some space between the conveying cone (C/10) and the structure (C/1). The conveying cone (C/10) consists of a cylinder ending down in a cone, the edge of the cylinder is bent outwards and closed on top by an airtight cover. Inside the cone (C/10) there is a radiator (C/18), crossed by a pipe, spiral in form (C/8), where the cooling gas is conveyed inside and outside element C. Along this pipe (C/8) we find a compressor (C/23) pushing the cooling gas forward, below the compressor there is a condenser (C/24) with a water-pipe (C/21) and a water outlet (C/22), below the condenser (C/24) there is an expansion valve (C/25). Below the radiator (C/18) there is the mixing chamber (C/4). The mixing chamber (C/4) consists of two parts: the top (C/11) and the bottom (C/14). The upper cone of the mixing chamber (C/11) is fastened with screws, thus leaving some space between the top of the cone and the structure. The upper cone of the mixing chamber ends down in a cylinder with outward bent edges. At the top of the mixing chamber upper cone (C/11) there is an opening (C/11a). Just above the upper cone of the mixing chamber (C/11) there is a metal sieve (C/26) covering the area between the inner walls of the structure (C/1) and the upper cone of the mixing chamber (C/11). On this metal sieve (C/26) there is metal wool (C/19), so that the conveying cone is placed in the metal wool. The metal sieve (C/26) prevents the metal wool (C/19) from falling down to the bottom of element C. On top, near the conveying cone (C/10), flue C/5 enters element C. At the entrance into element C there is a non-return valve (C/5a). The flue is connected to a pipe (C/7) conveying the fumes. This pipe, spiral in form, is smooth inside and resistant to H2SO4. Pipe C/7 crosses the cylinder (C/1a), reaches the upper cone of the mixing chamber (C/11) and goes into the mixing chamber (C/4) through opening C/11a. At the end of pipe C/7 there is a S-swirl vane (C/12). The teflon joint (C/28) makes its rotation easier. The swirl vane(C/12) is slightly sloping down. Just above the edge of the upper cone of the mixing chamber (C/11) there is a non-return device (C/13). The cylinder bottom ends in an opening leading into a dust conveying channel (C/15). Below this channel there is a dust collecting chamber (C/16). Near dust collecting chamber C/16 there is a timer-controlled electromagnetic valve (C/17). The inner wall of element C is made of metal and is resistant to H2SO4. The electric infrasonic wave device (C/9), the timer-controlled electromagnetic valve (C/17), the thermostats (C/20) and the compressor (C/23) pushing forward the cooling gas are controlled by control unit D/39. This is how element C is composed when it works in a system made up of elements A+B+ C+D+E, or A+B+C+D, or B+C+D, or B+C+D+E.

If element C works in a system not including element D, the electric infrasonic-wave device (C/9), the timer-controlled electromagnetic valve (C/17), the thermostats (C/20) and the compressor (C/23) shall be controlled by control unit C/27, because in that case element C has its own control unit (C/27). If element C works independently or in the C+E combination, at the beginning of flue C/5 there shall be a suction unit, which can consist of element X or Y depending on the use. Element C or the following combinations C+E, X+C, X+C+E, Y+C, Y+C+E are controlled by control unit C/27.

If element C works in the C+D, or C+D+E combination, element X or Y shall be placed at the beginning of the flue (C/5). The system shall be controlled by control unit D/39. If element C works in a A+B+C or B+C combination, such system shall be controlled by control unit C/27.

If element C works in a A+C+D, or A+C+D+E combination, flue C/5 shall be connected to flue A/19 and at the entrance of pipe C/5 into element C there shall be a suction system (B/5, /5a, /5b, /5c, /6, /9 /12, /13, /14), which otherwise shall be placed in element B, and sensor B/16. The system shall be controlled by control unit D/39.

If we wish to use element C in the C+D+E combination as a purifier for radioactive air, the inner elements, that is the structure (C/1), the removable cover (C/2), flue C/5, pipe C/7, the cooling gas conveying pipe (C/8), the conveying cone (C/10), the upper cone of the mixing chamber (C/11) the cylinder bottom (C/14), the dust conveying channel (C/15), the dust collecting chamber (C/16), the timer-controlled electromagnetic valve (C/17), flue C/30 and the metal wool shall be lead-clad.

If we use element C in a purifying system at a temperature up to 80°C, the structure (C/1), the removable cover (C/2), flue C/5, the non-return valve (C/5a), pipe C/7, the conveying cone (C/10), the upper cone of the mixing chamber (C/11), the swirl vane (C/12), the non-return device (C/13), the cylinder bottom (C714), the dust collecting chamber (C/16), the timer-controlled electromagnetic valve (C/17), the water pipe (C/21), the water outlet (C/22), the metal sieve (C/23) and flue C/30 can be made of GRP. 4. Element D - Fume Purifier

This element purifies fumes. It consists of two parts and precisely the main equipment (D I) and the ancillary equipment (D II). a) Element D I - Main Fume Purifier - Figure 4

This element has a metal structure (D/1) consisting of a cylinder (D/la) ending in a cone both on top and at the bottom. The upper cone is the removable cover (D/2) and the lower cone is the cylinder bottom (D/14). The structure (D/1) is based on feet (D/49). The cover (D/2) and the cylinder bottom (D/14) can be removed from the cylinder (D/1a) because they are applied by means of flexible rings (D/3a and D/3b). The fumes are conveyed through flue D/37 which starts from the cover.

Inside element D I, below the flexible ring (D/3a) there is a conveying cone (D/10) fastened with screws and suspended in element D I, thus leaving some space between the structure (D/1) and the cone (D/10).

The conveying cone consists of a cylinder ending down in a cone, the upper edge is bent outwards and the top is closed by an airtight cover. In the conveying cone there is an electric infrasonic wave device (D/9). At the bottom of element D I there is the mixing chamber (D/4). The mixing chamber consists of the upper cone (D/11) and of the cylinder bottom (D/14). The upper cone of the mixing chamber (D/11) is fastened with screws, thus leaving some space between the upper cone (D/11) and the structure (D/1). The upper cone of the mixing chamber (D/11) ends down in a cylinder with outward bent edges. At the top of the upper cone there is a metal sieve (D/40). On this sieve there is metal wool (D/.19), so that the conveying cone (D/10) is placed in the metal wool (D/19). The metal sieve (D/40) prevents the metal wool (D/19) from falling down into element D I. Above the upper cone (D/11) a flue (D/5) connects to element D I. At the beginning of flue D/5 there is a non-return valve (D/5a). Before entering element D I, the flue forms an elbow with an opening (D/5b). On this opening there are the ionizer (D/6), a fan (D/7), placed behind the ionizer and a non-return valve (D/8), placed ahead of the ionizer. Flue D/5 reaches the centre of element D I where it forms an elbow and goes down through opening D/lla into the mixing chamber (D/4). At the end of flue D/5 there is a S-swirl vane (D/12) with a teflon joint (D/41). The teflon joint makes its rotation easier. The swirl vane is slightly sloping down. On one side αf the mixing chamber (D/11) there is a non-return valve (D/13). A pipe carrying water under pressure (D/44) connects element D I I to element D I. This pipe (D/44) reaches element D I through a pipe fitting (D/45) ending in the steam diffusing equipment (D/46), placed at the top of the upper cone of the mixing chamber (D/11). The steam diffusing equipment (D/46) may be placed at both sides of the swirl vane (D/12). In that case, however, the pipe (D/44) carrying the water under pressure must be connected to flue D/5. The pipe fitting (D/45) connects to the pipe carrying water under pressure (D/44) at the beginning of the vanes (D/12). In the cylinder bottom (D/14) there is a dust collecting chamber (D/15) which is connected to the lower dust collecting chamber (D/16). A timer-controlled electromagnetic valve is placed ahead of dust collecting chamber D/16 to let the dust into element D II. b) Element D II Ancillary Fume Purifier - Figure 4

Behind the timer-controlled electromagnetic valve (D/.17) there is a pipe (D/8) conveying the dust into the dust collecting chambers (D/20 and D/20a). The dust collecting chambers are square-shaped and end in a pyramid with a partition (D/21) in the middle, which is lower than the walls. Dust collecting chamber D/20a has an exhaust outlet (D/22) at the bottom. This outlet leads into a channel (D/23) connected to the additional dust collecting chamber (D/26). At the top of dust collecting chamber D/20b there is a filter (D/24) for fine dust particles and at the bottom there is an electromagnetic valve (D/27). A partition separates the clean water tank (D/25) from dust collecting chamber D/20b. This partition is slanted to the right to let the clean water flow into the tank and forms an angle of 30°- figure 4 -. Next to the clean water tank (D/25) there is a tank containing water under pressure (D/33) which consists of a cylinder ending in a cone cut on top. The cylinder ends in cone at the bottom where we find an exhaust valve (D/34).

The water pipe (D/31) connects the tank containing the water under pressure to the clean water tank (D/25). Along this pipe (D/31) there is an electric pump (D/32) and at the end αf it there is a fan (D/30). An electric compressor (D/35) is placed near the top of the tank (D/33) which is connected to the air duct (D/38) and under the tank there is a fan (D/36). A pipe carrying water under pressure (D/44) is connected to tank D/33. At the beginning of this pipe there is a non-return valve (D/47). The pipe carrying water under pressure (D/44) connects to element D I. In the tank containing water under pressure (D/33) there is a float with a contact to engage the pump (D/42) and a float with a contact to engage the compressor (D/43). The air ionizer (D/6), the fan (D/7), the electric infrasonic wave device (D/9), the timer-controlled electromagnetic valve (D/17), the float with contact to engage the pump (D/42), the float with contact to engage the compressor (D/43) are controlled by control unit D/39. This is how element D is composed, if it works in following combinations A,B,C,D,E A+B+C+D, A+B+D, A+B+D+E, A+C+D, A+C+D+E, B+C+D, B+C+D+E, B+D, B+D+E, C+D, C+D+E .

If element D is used as an independent system, a sensor shall be placed in flue D/37 and it shall be controlled by control unit D/39.

If element D works as an independent system or in the D+E system, a suction fan shall be placed at the beginning of flue D/5. We can add element X or Y, according to the purpose.

If we want to use element D in the C+D+E system as a purifier for radioactive air, all inner parts shall be lead-clad, that is the structure (D/1), the removable cover (D/2), the flue (D/5), the conveying cone (D/10), the mixing chamber upper cone (D/11), the cylinder bottom (D/14), dust collecting chamber D/15, the dust collecting chamber D/16, the timer-controlled electromagnetic valve (D/17), the channel conveying the dust (D/18), dust collecting chambers (D/20a and D/20b), the exhaust outlet (D/22), the pipe (D/23), the clean water tank (D/25), the ancillary dust collecting chamber (D/26), the valve (D/27), the water drain pipe (D/31), the electric pump (D/32), the clean water tank (D/33), the opening with exhaust valve (D/34), flue D/37, the air duct (D/38) and the pipe conveying water under pressure (D/44), the convector (D/8) and the metal wool (D/19). If we use element D as an air purifier at temperatures up to 80°C, the following parts may be made of GRP: the structure (D/1), the removable cover (D/2), the flue (D/5), the non-return valve (D/5a), the non-return valve (D/8), the conveying cone (D/10), the mixing chamber upper cone (D/11), the swirl vane (D/12), the non-return device (D/13), the cylinder bottom (D/14), dust collecting chamber D/16, the timer-controlled electromagnetic valve (D/17), dust conveying channel D/18, dust collecting chambers D/20a and D/20b, the partition (D/21), the dust conveying pipe (D/23), the filter (D/24), the clean water tank (D/25), the additional dust collecting chamber (D/26), the electromagnetic valve (D/27), the sloping partition (D/29), the suction valve (D/30), pipe D/31, the electric pump (D/32), the clean water tank (D/33), the opening with exhaust valve (D/34), the valve (D/36), flue D/37, the air duct (D/38), the float with contact for the pump (D/42), the float with contact to engage the compressor (D/43), the pipe carrying water under pressure (D/44), the pipe fitting (D/45), the steam diffusing equipment (D/46) and the electromagnetic valve (D/47).

5. Element E - Final Purifier - Figure 5

This element is the final fume purifier. It is made up of a metal structure (E/1) consisting of a cylinder (E/1a). At the top of the cylinder there is a cone which is the removable cover (E/2), the lower part of the cylinder is the bottom (E/11). The structure (E/1) is based on feet (E/24). The cover (E/2) and the bottom of the cylinder (E/11) can be removed, since they are applied by means of flexible rings (E/3a and E/3b). A flue starts from the cover (E/20). Inside the cylinder there is a conveying cone (E/10) fastened with screws, thus leaving some space between the conveying cone (E/10) and the structure (E/1). The conveying cone (E/10) consists of a cylinder ending down in a cone, the cylinder upper edge is bent outwards. The conveying cone is closed on top by a tight cover. In the cone (E/10) there is an electric infrasonic wave device (E/9). At the bottom of element E there is the mixing chamber (E/4). The mixing chamber (E/4) consists of the upper cone (E/11) and of the cylinder bottom (E/14). The upper cone of the mixing chamber (E/11) is fastened with screws, thus leaving some space between the upper cone of the mixing chamber and the structure (E/1). At the top of the mixing chamber (E/11) there is an opening (E/11a). Just above the edge of the upper cone of the mixing chamber there is a metal sieve(E/22) stretching between the inner wall of the structure (E/1) and the upper cone of the mixing chamber (E/11). On this sieve there is metal wool (E/19), so that the cone is placed in the metal wool (E/19). The metal sieve (E/22) prevents the metal wool from falling into the lower part of element E. A flue (E/5) connects to element E above the upper cone of the mixing chamber (E/11). At the beginning of flue E/5 there is a non-return valve (E/5a). Before entering element E flue E/5 forms an elbow with an opening (E/5b). On this opening (E/5b) there is the air ionizer (E/6), behind the ionizer there is a fan (E/7) and ahead of the ionizer there is a non-return valve (E/8). Flue E/5 is smooth inside and resistant to H2SO4. After entering element E flue E/5 reaches the centre of element E and forms the elbow then it goes down into the mixing chamber (E/4). At the end of flue E/5 there is a S-swirl vane (E/12) with a teflon joint (E/23) which makes its rotation easier. The swirl vane (E/12) is slightly sloping downwards. Just above the upper cone of the mixing chamber (E/11) there is a non-return device (E/13). The bottom of the cylinder (E/14) is the lower cone of the mixing chamber (E/4) at the same time. At the bottom of the cylinder there is the dust conveying channel (E/15), which is connected to dust collecting chamber E/16 which ends in a cone. After the dust collecting chamber there is a timer-controlled electromagnetic valve (E/17) allowing the dust to go into the main collecting chamber (F/2) through pipe E/18. Outside element E there is a sensor (E/21). The air ionizer (E/6), the fan (E/7), the electric infrasonic wave device, the timer-controlled electromagnetic valve (E/17) and the sensor (E/21) shall be controlled by control unit D/39, if element E works in a system including element D, or by C/27 if element E works in a system which does not include element D, but rather element C. If neither element D nor element C are included, the system shall be controlled by E/25. If element E works as an independent system, it is possible to place a suction fan ahead of flue E/5. This can be either element X or element Y. In that case control unit E/25 shall control the system.

If we wish to use element E in the C+D+E system as a radioactive air purifier, the following parts shall be lead-clad, the structure (E/1), the cover (E/2), the flue(E/5), the conveying cone (E/10), the mixing chamber upper cone (E/11), the cylinder bottom (E/14), the dust conveying channel (E/15), dust collecting chamber (E/16), the timer-controlled electromagnetic valve (E/17), pipe E/18 - and flue E/20, the non-return valve (E/8) and the metal wool (E/19).

If element E is used as a purifier at a temperature up to 80°C the following elements may be made of GRP: the structure (E/1), the non-return valve (E/5a), the non-return valve (E/8), the conveying cone (E/10), the mixing chamber upper cone (E/11), the swirl vane (E/12), the non-return device (E/13), the cylinder bottom (E/14), dust conveying channel E/15, dust collecting chamber E/16, the timer-controlled electromagnetic valve (E/17), pifie E/18, flue E/20 and the metal sieve (E/22). 6. Structure F - Combination of elements A, B, C, D, E - Figure 6

In structure F elements are connected in the following order A,B,C,D,E. They are connected to each other by the flue, so that flue A/19 is connected to flue B/4, flue B/15 is connected to flue C/5, flue C/30 is connected to flue D/5 and flue D/37 is connected to flue E/5. Element B is connected by the mist collecting chamber (B/14), element C by the timer-controlled electomagnetic valve (C/17) and element E by pipe E/18 which is connected to the main collecting chamber (F/2) by pipe F/1. The fan (A/13), the ionizer (A/14), the timer-controlled electromagnetic valve (B/9), the sensors (B/16 and E/21), the infrasonic wave devices (C/9, D/9, E/9), the thermostats (C/20), the compressor pushing forward the cooling gas (C/23), the air ionizers (D/6, E/6), the fan (D/7 and E/7), the float with contact to engage the compressor (D/43) are controlled by control unit D/39.

7. Suction Fans - Figure 7 and Figure 8

The suction fans are illustrated in figure 7 and 8 and show element X - static suction fan, figure 7 - and element Y - rotating suction fan, figure 8. One can choose which of the two has to be used. The suction fan is placed ahead of elements C,D and E. It can be used as an independent system or in the various combinations with one of the above elements. The suction fan shall be the first element of the combination. a) Element X - Static Suction Fan - Figure 7

It consists of a suction fan for polluted air (X/1), which looks like a trumpet with inward bent edges. At the end of the trumpet there is a net covering the whole opening (X/2). Suction fan X/1 is connected to flexible pipe X/4. The electromotor housing (X/3) consists of a four-way pipe (X/3a, X/3b, X/3c). The first-way leads into the flexible pipe (X/4), on the second one (X/3b) there is a two-speed electromotor, the third way (X/3c) connects to pipe X/8. In the electromotor housing there is a suction fan (X/5) operated by the electromotor (X/6). Along the flexible pipe there is a sensor (X/7) controlled by control unit C/27, D/39 or E/25. The electromotor (X/6) is controlled by control unit C/27, D/39 or E/25.

If we want to use element X in the C+D+E combination as a purifier for radioactive air, its parts shall be lead-clad, that is the suction fan (X/1), the electromotor housing (X/3) and the flexible pipe (X/4). If we want to use element X as a purifier at a temperature up to 80°C, the suction fan (X/1), the net (X/2), the electromotor housing (X/3), the flexible pipe (X/4) and the fan (X/5) can be made of GRP. b) Element Y - Rotating Suction Fan - Figure 8

It consists of four suction fans for polluted air (Y/1a, Y/1b, Y/1c, Y/1d). These suction fans (Y/1a, Y/1b, Y/1c, Y/1d) look like the one described in paragraph 7. a

Every suction fan (Y/1a, Y/1b, Y/1c, Y/1d) has a net (Y/2) as described in paragraph 7. a). Suction fans Y/1a, Y/1b, Y/1c, Y/1d are connected to the main joint (Y/3) - figure 8 - which is connected to the rotating pipe (Y/4). On the main joint (Y/3) there is a sensor (Y/14) controlled by control unit C/27, D/39 or E/25, depending on which element the suction fan is placed. Below the main joint (Y/3) there is a gear-wheel (Y/5) with pinion (Y/6) which is fixed to the rotating pipe (Y/4). Below the gear-wheel (Y/5) at the end of the rotating pipe there is a teflon joint (Y/8). The teflon joint is connected to an elbow (Y/9) which goes on forming an angle of 95°. The teflon joint (Y/8) is placed in a case. The electromotor (Y/7) and its housing are fixed to the box (Y/Sa) so that the gear-wheel with the pinion fixed above the electromotor (Y/7) makes the pipe (Y/4) turn. The elbow (Y/9) continues into the electromotor housing (Y/10), which has three openings (Y/10a, Y/10b, Y/10c). The first opening (Y/10a) connects the two-speed electromotor to the elbow (Y/9); on the second opening (Y/10) there is the two-speed electromotor (Y/11); the third opening (Y/10c) leads into pipe Y/13 carrying compressed air. Inside the electromotor housing (Y/10) there is a suction fan (Y/12) operated by the two-speed electromotor (Y/11). Electromotor Y/7 and the two-speed electromotor (Y/11) are controlled by control unit C/27, D/39 or E/25.

If we want to use element Y in the C+D+E combination as a purifier for radioactive air, the inner parts shall be lead-clad, that is the suction fans (Y/1a, Y/1b, Y/1c, Y/1d), the main joint (Y/3), the rotating pipe (Y/4), the elbow (Y/9), the two-speed electromotor housing (Y/10) and pipe Y/13.

If we use element Y as a purifier for polluted air at. a temperature up to 80°C the suction fans (Y/1a, Y/1b, Y/1c, Y/1d), the nets (Y/2), the gear wheel with pinion (Y/6), the elbow (Y/9), the suction fan (Y/12) and pipe Y/13 can be made of GRP.

II. Working principles of each element of structure F

1. Element A - Heater with Convectors a) Use of element A with liquid fuel

The fuel is fed into the heating area (A/8) by opening the top (A/2) cover (A/3). By supplying the ionizers (A/14) with power we produce negative ions. The electric fan (A/13) introduces air which pushes the negative ions into the heating area (A/8) through pipe A/12 with the aid of the non-return valve. In the heating area the negative ions mix with air and fumes increasing the combustion. The spiral convector (A/16) makes the air circulate pushing the flame towards the main spiral convector (A/18). When in the heating area (A/8) there are enough fumes, they are conveyed by the side convectors (A/17). This results in energy saving and recovery. The fumes flow into element B through pipe A/9 and flue B/4. The fume conveying device (A/20) prevents the fumes from going back into element A. The water comes through the water pipe (A/9) and is drained through the water outlet (A/10). In the probe (A/21) there are cables supplying element A with power. The tip of the flame convector (A/16) is bent upwards since the fuel is fed through the upper hole of element A. b) Use of element A with solid fuel

The fuel is fed into the heating area through opening A/4. The working principle is the same as described in the above paragraph 1.a), except for the flame convector (A/16) which has a donward bent tip, beacause the fuel is put at the bottom of element A.

2. Element B - Heat Accumulator - Figure 2

The fumes flow into element B from element A through flue B/4. In the meantime the metal mass (B/10), which is a good heat conductor, is being heated up. The smoke cools down and part of it turns into mist. The metal mass (B/10) heats up the water pipe (B/11). The water is conveyed through the water inlet (B/8) and flows in pipe B/11 inside element B, then into element A through the water outlet (B/7). The two-speed electromotor (B/9) operates the suction fan (B/12) placed in the electromotor housing (B/5). The suction fan draws the fumes in from element A conveying them through flue B/4 and sends them into element C through flue C/5. While the fumes flow into element B part of them are condensed and the condensed fumes are collected in the mist collecting chamber (B/13), then they flow into the lower mist collecting chamber (B/14). The timer-controlled electromagnetic valve opens and allows the mist to flow into the mist collecting chamber (B/14), then both the mist and the dust flow into the main collecting chamber (F/2) through pipe F/1. The two-speed electromotor (B/9) is controlled by a speed governor, if we use liquid fuel, we shall turn on the low speed, if we use solid fuel, we shall turn on the high speed.

The two-speed electromotor (B/9) uses less energy than the energy accumulated by element B, so we can use energy coming from element B energy even after element A has stopped.

3. Element C - Fume Regenerating Equipment

The fumes coming from element B flow into element C through flue B/5 and are conveyed into pipe C/7. The non-return valve (C/5a) prevents the fumes from going back into element B. While flowing in pipe C/7 the fumes cool down and are condensed. The quick cooling down makes it easier for the radiator (C/10) to work. The fumes and the mist are conveyed through flue C/7 and the swirl vane (C/12) pushes them into the mixing chamber (C/4) which is cone-shaped bath at the top and at the bottom. The condensed fumes fall to the bottom (C/14) and owing to the shape of the container (C/4) flow through the dust conveying channel (C/15) and finally into dust collecting chamber C/16, then the timer-control led electromagnetic valve opens to let them into the main collecting chamber (F/2) through pipe F/1. The fumes remaining in the mixing chamber (C/4) are forced upwards into the mixing chamber upper cone (C/11) inside element C by the suction fan (B/12). Being hindered, the fumes cannot go back into the mixing chamber. The obstacles are the outward bent edge of the mixing chamber upper cone (C/11) and the non-return device (C/13). The fumes flow upwards through the metal sieve (C/26), the metal wool (C/19), the radiator (C/18) (placed in the metal wool) and the cone (C/10) to the space above; then they flow into flue C/30 which continues into flue D/5. The radiator (C/18) cools the metal wool (C/19) and element C, so that mist is formed on the radiator (C/18) and on the metal wool (C/19). The electric infrasonic wave device (C/9) shakes the radiator (C/18) and the metal wool, so that the drops deposited on the metal wool (C/19) and the radiator fall down to the upper cone of the mixing chamber (C/11). Then they flow into the mixing chamber (C/11) and down to the bottom (C/14). The radiator (C/18) cools down and makes the gas flow through the pipe conveying the cooling gas (C/8). The gas is pushed forward by the compressor (C/23), which pushes the gas into the pipe where the cooling gas flows (C/8) with the aid of the condenser (C/24) and of the expansion valve (C/25). The condenser (C/24) taking the energy from the water pipe sends the water to the boiler and to the accumulator. 4. Element D - Fume Purifier - Figure 4

After leaving element C, the fumes (partly purified) flow into flue D/5 and into element D. The non-return valve (D/5a) prevents the fumes from going back to element C. Before the fumes flow into element D I, negative ions are produced by the air ionizer (D/6) which is supplied with power. The electric fan (D/7) pushes the negative ions into element D I. The negative ions pass by the non-return valve which prevents the fumes from going into the ionizer (D/6) from flue D/5. As a result the negative ions mix with the fumes in flue D/5, then move to the swirl vane (D/12) and to the mixing chamber which is cone-shaped both on top and at the bottom. The steam sprayed by the steam diffusing equipment (D/46) comes from element D II through the water pipe (D/44) and through the pipe fitting (D/45) placed on the mixing chamber upper cone (D/11). Then the steam goes to the mixing chamber (D/4), so that the water coming from element D II is changed into steam. In the mixing chamber the steam mixes with the fumes and the negative ions and the mixture is moved by the swirl vane (D/12). The steam purifies the remaining dirty fumes. The dirty steam is condensed into drops which fall down to the bottom (D/14) and owing to the container shape (D/14) flow into dust conveying channel D/15, then into dust collecting chamber D/16 and are forced by the timer-controlled electromagnetic valve (D/17) through dust collecting channel D/18 into element D II. The purified fumes, which have not fallen down to the bottom with the steam, are forced upwards to the upper edge of the mixing chamber cone (D/11) inside element D I by the suction fan (B/12). The fumes are conveyed through obstacles which prevent them from going back to the mixing chamber (D/11). Such obstacles are the outward bent edge of the mixing chamber upper cone (D/11) and the non-return device (D/13). The fumes go upward through the metal sieve (D/40) and the metal wool (D/19). As the fumes proceed upwards the condensed fumes deposit on the metal wool (D/19). The electric infrasonic wave device (D/9) shakes the metal wool (D/19) so that the drops fall down to the mixing chamber (D/11) upper cone and to the bottom (D/14). The remaining fumes, which are nearly quite purified, are conveyed upwards by the cone (D/10) and then into flue D/37 and finally into flue E/5.

The dust mixed with water flows through the dust conveying channel (D/18) into element D II, which is placed at a level lower than element D I, therefore we do not need a pump. Dust conveying channel D/18 leads to dust collecting chamber D/20a. The heavy particles flow to the bottom down the pyramid walls through dust conveying channel D/22 and through pipe D/23 to the ancillary dust collecting chamber (D/26). Part of the water flows into dust collecting chamber D/20b. This is made possible by the partition (D/21) existing between both dust collecting chambers (D/20a and D/20b). As soon as the water flows into dust. collecting chamber D/20b the fine particles remain at the top and deposit on the filter. The valve (D/27) opens intermittently as the heavy particles come into dust collecting chamber D/20b. The clean water is carried through the filter (D/24) into dust collecting chamber D/20 and flows through the outlet (D/28) to the wall (D/29) and into the clean water tank (D/25). The clean water flows through the pipe (D/31) to the clean water tank (D/25) and to the tank containing the water under pressure (D/33). The electric compressor (D/35) pushes the air through the air duct (D/38) to the tank containing water under pressure (D/33). The valve (D/36) prevents the water from reaching the electric compressor (D/35). The pressure pushes the water from the tank containing water under pressure (D/33) by means of the valve (D/47) to the pipe carrying the water under pressure (D/44) into element D I. The dust remaining at the bottom of the clean water tank (D/33) is conveyed to the opening by the exhaust valve (D/34). The water level in the clean water tank (D/29) is regulated by the float with contact to engage the pump, (D/42), the float with contact to engage the compressor (D/43) regulates the pressure in the clean water tank (D/33). 5. Element E - Final Purifier - Figure 5

After the fumes have been totally purified, they flow into element E after leaving element D I through flue E/5. The non-return valve (E/5a) placed along the flue prevents the fumes from going back into element D I. Before the fumes enter element E, negative ions are produced by the electric ionizer. The electric fan (E/7) forces the air which pushes the negative ions into element E, the negative ions and the air pass near the non-return device (E/8), which prevents the fumes from passing from the flue into the air ionizer (E/6). The negative ions mix with the fumes and the mixture is conveyed into flue E/5 and then into the mixing chamber (E/4) by the swirl vane. The mixing chamber is cone-shaped both on top and at the bottom. The swirl vane (E/12) moves the fumes mixed with the negative ions. The negative ions make the fumes particles heavier therefore they fall down to the bottom of the cylinder (E/14), then owing to the cylinder shape they flow through dust conveying channel E/15 into dust collecting chamber E/16 and the timer-controlled electromagnetic valve sends them through pipe E/18 and pipe F/1 into the main dust collecting chamber (F/2). The purified fumes which have not reached the cylinder bottom (E/14) are forced upwards along the inner wall of element E by the suction fan, owing to the edge of the mixing chamber (E/11) upper cone, and to the non-return device (E/13). The fumes are prevented from returning into the mixing chamber (E/11) by the various obstacles. The fumes flow through the metal sieve (E/22) and the metal wool (E/19). While going upwards the fumes are condensed and the condensed fumes deposit on the metal wool (E/19). The infrasonic wave device (E/9) shakes the metal wool (E/19), so that the condensed drops fall down to the mixing chamber uppercone (E/11) and to the bottom (E/14). The remaining fumes are fully purified and flow along the cone (E/10) into the above area then through flue E/20 into the chimney. The sensor (E/21) regulates the quantity of negative ions present in the atmosphere and the emission of negative ions according to that quantity.

III. Working principle of the suction fans

Both suction fans, X and Y, work according to the same principle. Element X is placed at the source of the polluted air, element Y is placed at the outlet where the polluted air goes into the atmosphere.

1. Element X - Static Suction Fan - Figure 7

In element X the two-speed electromotor (X/6) makes the suction fan (X/5) draw in the polluted air through the suction fan (X/1), the flexible pipe (X/4) and pipe X/8 pushing it into elements C, D, or E, through flues C/5, D/5, or E/5, depending on which element is placed. The net (X/2) prevents heavy particles from going into element X. The pipe (X/4) should be flexible so as to be placed at the source of the polluted air. The sensor (X/7) is controlled by control unit C/27, D/39 or E/25, depending on the element connected the static suction fan (X) and controls air pollution.

2. Element Y - Rotating Suction Fan - Figure 8

In element Y the two-speed electromotor (Y/11) makes the suction fan (Y/12) draw in the polluted air through the four pipes conveying polluted air (Y/1a, Y/1b, Y/1c, Y/1d) and pushes it through pipe Y/4, the teflon joint (Y/8) and the elbow into element C, D, or E through flue C/5, D/5 or E/5, depending on which element it. is placed. The net (Y/2) prevents heavy particles from going into element Y. The electromotor (Y/7) operates the gear wheel (Y/6) transmitting the rotation to the gear wheel of pipe Y/5 which makes the pipe (Y/4) and the suction fans (Y/1a, Y/1b, Y/1c, Y/1d) turn. The sensor (Y/14) is controlled by control unit C/27, D/39 or E/25 and controls the degree of pollution.

IV. Elements used as independent or as ancillary equipments 1. Element A as an independent equipment

If element A is used as an independent equipment it works as the system described in paragraph II. The only difference lies in the fact that element A is directly connected to the chimney by a flue (A/19). The improvement is due to the flame spiral convector (A/16) in the main spiral convector (A/18) and the fume spiral convectors (A/15) placed near the side convectors (A/17), which make it possible to save energy, because air increases the heat-degree enriching the fumes with negative ions. If element A works independently, the water is carried by pipe A/9 and after being heated up it is conveyed through pipe A/10.

2. Elements A and B as an independent equipment

Element A works as described in paragraph II, the same applies to element B, with the difference that instead of flowing into element C through flue B/15, the fumes are conveyed into the chimney. If we add element B to element A, we will regenerate the fumes increasing the heat degree, which means additional energy saving. 3. Elements A, B, C as an independent equipment

The three elements work exactly as described in paragraph II, with the difference that instead of being connected to element D by flue C/30, element C is connected to the chimney. In this case total regeneration of the fumes is possible.

4. Elements A, B, C, D as an independent equipment

The four elements work as described in paragraph II, with the difference that the fumes flow into the chimney, instead of being conveyed into element E through the flue. With this system the fumes go into the air after being fully purified.

5. Elements A, B, D as an independent equipment

The three elements work as described in paragraph II, but in this case element B is connected to element D through flue B/15 by flue D/5. This system purifies the fumes.

6. Elements A, B, D, E as an independent equipment

They work as described in paragraph IV, but in this case element E is placed behind element D as described in paragraph II. 7. Elements A, C as an independent, equipment

Both elements work as described in paragraph II, but in this case element A, instead of element B, is directly connected to element C through flue A/19. The fumes flow into element C through flue C/5, in this case a suction fan, which otherwise would be placed ahead of element B, is placed along flue C/5 between elements A and element C. This system draws the fumes out of element A and pushes them into element C. Element C is directly connected to the chimney through flue C/30, instead of being connected to element D. Since element B is not included in the system, the water flows into element A through the water pipe (A7) and through pipe A/10.

8. Elements A, C, D as an independent equipment

The three elements work as described in paragraph II. Element A is directly connected to element C, as described in paragraph IV 7. Between element A and element C there is a suction fan. Instead of being connected to element E, element D is directly connected to the chimney by flue D/37. Since element B is being left out, the water flows into element A and out of it as described in paragraph IV 7. 9. Elements A, C, D, E as an independent equipment

They work as described in paragraph IV 8., but in this case element E is placed behind element D as described in paragraph II.

10. Elements B, C as an independent equipment

This equipment is used for polluted air at high temperatures, for example in foundries and heating plants. Element B draws in hot smoke or air by means of the suction fans (B/5, /6, /9, /12, /13, /14). The fumes flow through flue B/4 as in described in paragraph II, but pipe B/7 does not lead to the boiler (A/1). Element C is directly connected to the chimney through flue C/30 instead of being connected to element D.

11. Elements B, C, D as an independent equipment

They work as described in paragraph IV .10., but in this case element C is connected to element D as well, as described in paragraph II. Element D is directly connected to the chimney or to the open air through flue D/37, instead of being connected to element E. 12. Elements B, C, D, E as an independent equipment

They work as described in paragraph IV 11., but in this case behind element D there is element E too, as described in paragraph II. Even in this system the flue can lead to the open air through flue E/20 without using the chimney.

13. Elements B and D as an independent equipment

This equipment can be used to purify polluted air at high temperatures.

Element B is directly connected to element by flue B/15. The fumes flow into element D through flue D/15. Element B works as described in paragraph IV 10. for the equipment including element C, but element D is directly connected to the chimney by flue D/37 instead of being connected to element E. This equipment can be used as a partial hot air regenerator or as hot air cleaner.

14. Elements B, D, E as an independent equipment

This equipment works as described in paragraph IV 13., but in this case there is element E behind element D, as in the equipment described in paragraph II. With this equipment the fumes or the air can be sent back into the atmosphere through flue E/20.

15. Elements C, X or C, Y as an independent equipment

Elements X or Y draw in the fumes and the polluted air. The fumes and the air flow to the chimney or into the atmosphere through flue C/30, but they do not flow into element D. With this equipment we recover heat from hot air, in order to heat the water up. The fumes and the polluted air are partiallly purified and cooled. This equipment can be used as an air-conditioning unit. 16. Elements C, D, X or C, D, Y as an independent equipment

This equipment can be used to purify polluted air. The suction fan is placed ahead of element C, as described in paragraph IV 15. Elements C and D work as described in paragraph II, in this case, however, the fumes and the air do not flow into element E, but rather from element D through flue D/37 and into the atmosphere. This equipment can be used as an air-conditioning unit, or as an air humidifier.

17. Elements C, D, E, X or C, D, E, Y as an independent equipment

These elements work as described in paragraph IV 16., in this case, however, behind element D there is element E as well, as described in paragraph II. The smoke and gas conveying pipe can be connected to the chimney or lead to the atmosphere. This equipment can be used as an air-conditioning unit or as an air humidifier, or to enrich the air with negative ions by means of lead-clad parts, as shown in paragraph I. This equipment can be used as a purifier against radioactivity, after an accident occurs at a nuclear power station. 18. Elements C, E, X or C, E, Y as an independent equipment

They work as described in paragraph IV 15. for the C+X or C+Y system. In this case however the fumes and the air flow into element E through flue C/30 and flue E/5, then they flow to the chimney or go into the atmosphere through flue E/20. This equipment can be used as an air-conditioning unit and to enrich air with negative ions.

19. Elements D, X or D, Y as an independent equipment

Element D works as described in paragraph II. In this case, however, it. can be used to purify polluted air. Flue D/5 is connected to element X or Y as described in paragraph IV 15 for element C. Elements X or Y draw the air into element D. The fumes or the air flow through flue D/37 into the chimney or go into the atmosphere. This system can be applied to purifiers and air humidifiers.

20. Elements D, E, X or D, E, Y as an independent equipment

This equipment can be used to purify polluted air. Element X or element Y is placed ahead of element D, as described in paragraph IV 19. Otherwise element D and element E work as described in paragraph II. The fumes go into the air through flue E/20. This equipment can be used as an air humidifier or as an equipment to enrich the air with negative ions.

21. Element E as an independent equipment

Element E works as described in paragraph II. It can be used to purify the air with a lower pollution degree. This element is not connected to any other element. The air flows from element E through flue E/20 into the atmosphere.

22. Elements E, X or E, Y as an independent equipment

Element E works as described in paragraph II. This equipment is used to purify the air with a lower degree of pollution.
