Title:
EXHAUST ENERGY EXTRACTOR
Document Type and Number:
WIPO Patent Application WO/2003/060302
Kind Code:
A1
Abstract:
An exhaust emergy extractor has an exhaust chamber consisting of a heat exchange drum (01) in which an inner drum (02) is heated by exhaust supplied to the heat exchange drum (01) and by subsequent heliostat/s. The heated refrigerant in the inner drum (02) runs through a turbine system cooled by a coolant system at its exit end to become condensed liquid and propelling gas; the liquid condensate meets the end propelling gas in a spray drum (00) after running through a second turbine (after re-heating) to be colled to liquid by refrigerant, thus creating a vacuum effect for the propellant gas. Condensate receptacle/drainage system (072) are present in the flue/exhaust chimney (07) to cope with fall in heat temperature due to flue/exhaust extraction.

Description:
EXHAUST ENERGY EXTRACTOR Background Art This invention relates to an exhaust energy extractor.

Technical Field Exhaust is discharged into the air from electricity and in- dustrial plants, resulting in pollution and waste of energy.

This invention seeks to utilize the energy of exhaust and provide for partial removallremoval of pollutant/s.

Disclosure of the Invention According to this invention, there is provided a turbine system using gas from ammonia liquid/solution as power drive.

(Pure liquid ammonia is an alternative.) The turbine system has a heat exchangor (with refrigerant/coolant water) at the exit end. Condensed matter from the propellant gas is drained by a side duct system with liquid collector at the exit end and goes to join the escaping end propellant fluid in a spray drum. The spray drum has valve and duct leading to a heat exchange drum inside an exhaust chamber into which exhaust is run. So on receiving heat from the exhaust the propellant fluid (ammonia liquid) gasifies, expands and, after passing through heliostat points, enters the turbine system. The end exhaust is discharged, after washing bY water /sea water or further anti-pollution treatment, at e. g. sea level. Propellant fluid content adjustment device provide for a stable percentage mix for the propellant fluid. (Compression , heat recovery and pumping systems for fluid are present.) A specific embodiment of the invention is set opt in the example below by reference to the drawings.

Brief Description of Drawings Fig. 1 represents, in perspective, an HD (external chamber) of an exhaust energy extractor, looking from the side, with the external wall removed. Similarly, Fig. 2 shows a spray drum.

With reference to Fig. l, the exhaust energy extractor has an HD01 (external chamber) which is an exhaust chamber (with valves, ducts, connexions, etc. ) with an ID02 (heat exchange drum, with ducts, valves and ducts, etc. including a fluid passage connexion to a turbine system (not shown). (See also Fig. 2. ) The turbine has 2 parts, the first has a water cool- ant system at its exit end, and there is a liquid collector with a transport duct leading to a spray drum 00 so that the propellant gas ensuing is reheated by exhaust or heliostat , for example, again and enters a second turbine system coaled by a refrigerant at the exit end. The ensuing. fluid then enters the spray drum to meet the first condensate and water from a fluid feeder. The new ammonia liquid ( after concentration adjustment by an adjustment device) is then conveyed to the heat exchange drum ID02. (Condensate re- ceptacle/drainage system 072 exist in flue/exhaust chimney.

Best Mode of Operation 1. Exhaust is led into the external chamber HD01 via inlet valve 03 to heat up the heat exchange drum 02 and leaves at exit valve 04, to be washed by water in a washing room and discharge, e. g. at low sea level.

2. The fluid content in the heat exchange drum 02 gasifies and expands, only to be further heated by heliostat at helio points (passage points with black external coloring on the ducts and transparent heat trap).

3. On entering the first part of the turbine system, the propellant fluid is cooled by water coolant at the exit end to deposit liquid condensate at a liquid collector to run into the spray drum 00 later, while the gas- eous content continues forward.

4. The gaseous content is reheated (e. g. by exhaust and heliostat techniques) and passes through a second turbine system and cooled by a refrigerant to become a liquid to meet the liquid condensate in the spray drum below.

*Fig. 3 shows, in perspective, the inside view of an exhaust chimney 07 with condensate receptacle/drainage system 072 with the wall on the viewing side removed.

N. B. Control of fluid pressure is by multiple valving.

Pump use and throttling are a normal part of operation.
