MOBILE GAS TURBINE PLANT FOR THERMOCHEMICAL DISINFECTION OF POULTRY AND LIVESTOCK BUILDINGS Russian patent published in 2024 - IPC A61L2/06 

FIELD: agriculture.

SUBSTANCE: mobile gas turbine plant includes a base frame, on which a motor mount is installed with the help of two hinged assemblies, the angle of inclination of which relative to the base frame is carried out by a hydraulic lift. Ejector attachment and gas generator are arranged on motor mount. Ejector attachment is formed by two conical parts and a cylindrical part. Spraying nozzles are arranged on one of the conical parts. Gas generator represents aircraft turbojet engine with jet tube. Gas generator is covered from above with protective hood. On both sides of base frame there are two tanks for disinfectant solution and container with storage battery for starting aircraft turbojet engine. Plant operation is controlled from panel of control and monitoring parameters of aircraft turbojet engine, which is installed in metal container, which is mounted on fuel tank. Aircraft turbojet engine is configured to limit rotor speed of aircraft turbojet engine in range from 52% to 60% by means of adjustable stop of control lever of throttle valve of fuel supply and control system of aircraft turbojet engine. Inner diameter of the cylindrical part D_ej of the ejector attachment for the aircraft turbojet engine relates to the internal diameter of the outlet section of the jet pipe D_jp of the aircraft turbojet engine as: D_ej/D_jp = 1.8…2.2, wherein the distance L between the plane of the outlet section of the jet pipe and the plane of the inlet to the air ejector in the operating mode is from 1.7 to 2.0 calibres D_jp of the outlet section of the jet pipe, namely: L = (1.7…2.0)×D_jp. Outlets of spraying nozzles for supply of disinfectant are directed towards direction of gas-air flow in ejector attachment.

EFFECT: reducing the temperature of gases leaving the jet pipe of the turbojet engine both by selecting the optimum operating mode of the engine by its rotor speed and by selecting the geometrical parameters of the ejector attachment to achieve maximum value of atmospheric air ejection coefficient in order to mix it with gas leaving the jet pipe, and to reduce its temperature before supply to the treated room.
