The present invention relates to an improved Industrial chimney assembly system - an industrial S.P.M. separator -cum - emission converter to separate and remove hazardous pollutants and suspended particulate matters (S.P.M) present in the flue gases. A cleaner flue gas is thus discharged into the atmosphere * through the chimney which meets the pollutiion control standard, There are disadvantages in the present system of flue gas discharge to the atmosphere and abiding with pollution control standard. One of the main disadvantage with the present system is that height of chimneys are made very large so as to enable the polluted flue gas gets blown away in the atmosphere keeping the surrounding area free of suspended particles. Such large chimneys enhances cost and is not effective to ensure that suspended particles are blown away in the atmosphere. Another disadvantage with the present system of disposal of flue gas wherein the flue gas with suspended particles and other gases are ejected under pressure through an appropriate nozzle in the form of a high velocity jet so that the flue gas rises high in the atmosphere to be blown away. Sometime an auxiliary air jet is also used to blow away the flue gas into the atmosphere. These systems are very expensive and also not satisfactory as it does not meet the pollution standards.Further disadvantage with another system of flue gas disposal wherein air is blown in the zone of its upper outlet in the form of a jet or jets which surrounds at least part of the periphery of a central jet formed by the flue gas means are also provided to introduce the auxiliary gas in a centrifugal direction into the flow of the said flue gas/ at a small distance below the upper outlet. This system is found to be very expensive and gives unsatisfactory results. Therefore/ the main object of the present invention is to provide an improved chimneys with reduced height and is simple and economic which can be manufactured from indigenous materials. Another object of the present invention is to provide three integrated functionary chambers through which the flue gases from the chimneys will pass through for step by step conversions/ absorptions and separations for a cleaner flue gas. A further object of the present invention is to propose separation of suspended particulate matters (S.P.M) completely from outgoing chimney flue gases. Yet another object of the present invention is to propose removal of principal pollutants of flue gases by conversion and absorption process and reduce unnatural heat pollution of industrial surroundings and maintaining standard humidity. A still further object of the present invention is to propose improvement of furnace efficiency by controlling the rate of flow of flue gas. Yet a further object of the present invention is to propose use of liquid chemicals with water for the absorption process of pollutants of the flue gas. In accordance with the invention, there is provided an improved industrial chimney assembly system - an industrial S.P.M.

Fiq. 1 shows the present invention of an improved industrial chimneys assembly consisting of the four integrated chamber1 and four external functionary chambers. The component parts of four integrated chambers of Fig. 1 are as under!- 1 . MAIN_REACTOR_CH AMBER P. - over flow connecting means. ^2 ~" outlet of hot air connecting means. ?2 - fresh liquid connecting means.

E, F - pressure gauges. V-,/ V2 - valves P, - air line / or air tube. 1. CHIMNEYS_CAP B - air blower M - motor P - pump With the entry of the flue gases through the inlet (C) into the middle reactor chamber (2), a high jet of air along with liquid is sprayed through an air connecting means (T.,) and the liquid connecting means (P3) respectively/leading to the first phase of conversion. Therefrom/ it will enter into the main reactor chamber (I)/ where it gets deflected and passes over to the liquid solution. While it passes through this chamber/ the soots will be deposited and is drained out through a liquid overflow connecting means (P4) when it reaches a certain level. Here/ conversion/ absorption and separation will take place step by step. Therefrom/ it will pass through a number of baffles and then enters into the third integrated heat exchange chamber. Here/ a hot air connecting means (H2) is placed horizontally/ in order to lead hot air along with the high speed of outgoinc flue gases. Therefrom, the flue gases will pass out through the outlet (D) of the chimneys with a high speed to the atmosphere 90 - 95% S.P.M. free and 80-90% hazardous pollutants free.Liquid from the main reactor chamber (1) subsequently enters into the waste liquid chamber (8) through a liquid connecting means (P4) and then passes into the filter chamber (6) through inlet (Rfc)/ where the liquid gets filtered. The filtered liquid is transmitted from filter chamber (6) to the reservoir (5) by means of a connecting means of the outlet (PT) to the inlet (P'). Again/ the fresh liquid is transmitted from reservoir (5) to the middle reactor chamber (2). Therefrom/ the liquid passes to the main chamber (1) and then again to the filter chamber (6). Thus the liquid solution maintains a cyclic circulation throughout the process. Thereafter/ at a certain interval the liquid level will decrease due to being used up and also due to vaporisation effect. When the liquid level will go down below the required level/ instead of the liquid circulation atmospheric air (02) circulation will start through the air (O2) inlet (A.^. Again liquid level on being refilled through the fresh liquid connecting means (P2)/ then the liquid circulation will start again instead of air (02) circulation. The switching over to liquid and air circulation process and vice-versa depends on refiling of liquid into the main reactor chamber. Thereafter/ the deposited soot is drained out from the filter chamber (6) through the soot outlet ^2) into the soot drum (T) and then finally deposited into the trolly (V). A sunshed (Tg) is provided with the soot drum (T) to protect the deposited soot from the direct sunshine. A heat exchange chamber (3) is attached with the chimneys or shell which contains a numbers of holes (h) at the bottom and an outlet of hot air (H,) is provided at its top. The rate of flow of hot air can be regulated by closing and opening of the said holes (h) to maintain the unnatural heat pollution/or humidity. A sensor (S) is fitted with main chamber (I)/ which maintains the liquid level as required. Air is compressed ith the help of an air blower (B) into the air tank (10) through an air connecting means (P,). Another air connecting means (T^) is connected from the air tank (10) to the middle reactor chamber (2). Here/ V-j^ and V_ are two valves and E and F are two pressure gauges/ which regulates the air pressure and indicate the required pressure respectively. Another fresh liquid connecting means (Po) is fitted into the middle reactor chamber (2) and the other end of the connecting means (P3) is connected with the reservoir. Another connecting means (?6) is connected from the middle reactor chamber (2) to the waste liquid chamber (8)/ in order to drain out the remaining waste liquid to the filter chamber (6) for filtration. A rhombus shape structure is fitted at the outlet of the chimneys in order to protect rain water to drop inside the chimneys and to create a centrifugal force of the outgoing flue gases into the atmosphere at a maximum height. At the time of load-shedding/or failure of the air blower (B), the liquid level goes down through the connecting means (Pc) into the safety chamber (7) and then into the waste liquid chamber (8) and finally into the said filter chamber (6). A non-return Electro - magnetic valve assembly ( not shown in fig. 1) is fitted inside the safety chamber (7). The air blower (B) plays a vital role in the said invention. It acts as a forced draught and maintains the standard humidity of atmosphere by cooling and drying the outgoing flue g ases. It should besides be noted in this respect that the hot air is taken from the hot air chamber (3)/ is pre-heated in a noticeable manner by the hot combustion gases pass through the chimney column (9). It has the advantage of reducing the power required to bring this air to a pre-determined temperature and also of cooling the said chimneys colum (9)/ thus preventing any possible excessive temperature in the case of very hot combustion gases. The invention described hereinabove is in relation to a non - limiting e-nbodiment and as defined by the accompanying claims. WE CLAIM: 1.
