Disclosed is a contaminated waste steam heat recovery apparatus 10 and method therefore which includes a primary condensing unit 38, a low pressure water washing unit 26, a liquid to liquid heat exchanger 36 and a vent fan 31. Waste gas is ducted from fryer 11 to a de-super-heating chamber 14 wherein superheated steam is converted to saturated steam by spraying water into the steam using spray nozzles 15. The gas is then introduced into a vertically disposed air to liquid heat exchanger 16 and is drafted downward therethrough.

A plurality of condensate trays 19 are disposed below the bottom end of heat exchanger 16 in a cascading fashion to collect hold the condensate in the airflow path such that it will absorb some of the heat still present in the remaining waste gas. An oil outlet 22 is provided at the top of collection basin 22 for drawing off concentrated oil 23. The waste gas is pulled into a low pressure water washer 26 where it is washed by a second set of spray nozzles 15. Waste gas and water are sucked downward through a set of turbulence inducing baffles 28. The remaining waste gas is sucked out though exhaust tube 30, using vent fan 31, and vented to the atmosphere.

Fine particles of dust and other pollutants in gas streams are agglomerated to form larger particles which are more easily filtered in downstream processing. In one embodiment, particles in successive portions of the gas stream are charged with opposite polarity, and the gas stream is introduced into an Evasé portion (12) to slow it down. Particles of different sizes have differential deceleration and therefore mix generally in the direction of flow, leading to agglomeration of oppositely-charged particles. In another embodiment, a gas stream is divided into substreams in respective parallel passages, and the particles in adjacent passages are charged to opposite polarity. Deflectors at the downstream end of the passages cause substreams of particles of opposite polarity to mix, with resultant agglomeration of oppositely charged particles.

The invention discloses a photomagnetic dual-response Pickering emulsion coalescence reaction system and its application. Firstly, Fe3O4 nano-particles are prepared by a hydrolysis process; secondly, the Fe3O4 nano-particles are used as crystal nucleus to prepare Fe3O4/TiO2 composite nano-particles by a butyl titanate hydrolysis process; thirdly, surface hydrophobic chemical modification is carried out on the Fe3O4/TiO2 composite nano-particles by the use of alkylsilane; and finally, emulsification is carried out to obtain the photomagnetic dual-response Pickering emulsion coalescence reaction system. The above method is simple and has strong operationality. Directional migration of the emulsion and recovery of the nano-particles can be realized through magnetic response (magnetism method). By photoresponse (UV irradiation), the nano-particles adsorbed on the surface of the emulsion are changed from the non-active property to the active property, thus leading to coalescence between adjacent emulsions. By simple non-intrusive methods such as the magnetism method and UV irradiation, etc., the emulsion coalescence reaction system undergoes a chemical reaction at fixed point (reaction site) and at a fixed time (response time). The photomagnetic dual-response Pickering emulsion coalescence reaction system has a good application prospect in the industry field.
