SU1472058A1 - Air-conditioning arrangement for compartments of continuous tobacco fermentation line - Google Patents

Abstract

The invention relates to the tobacco and fermentation industry and can be used in continuous fermentation lines. The purpose of the invention is to save energy and improve the quality of fermented tobacco. The device consists of a combined mixer, made in the form of a vertical cylinder 1. Along the axis of the vertical cylinder 1 passes a heat exchanger in the form of a steam pipe 2, from which air (recirculation and external) is heated, and the humidification of the resulting mixture occurs by steam through a humidifier 3, located below the blowpipe 5 of the fan 4. The droplets formed as a result of the condensation of the vapor are deposited and removed through the trap 6. Attaching the vertical cylinder 1 to the blower steam The tube 5 of the fan 4 allows the air flow to swirl tangentially, which promotes better mixing of the air mixture and more complete removal of heat from the steam pipe 2. 4 sludge.

a vertical cylinder 1. The axis of the vertical cylinder 1 passes through a heat exchanger in the form of a steam pipe 2, from which air is heated (recirculation and external), and the resulting mixture is moistened by supplying steam through a steam humidifier 3 located below the discharge pipe 5 of the fan 4 The droplets formed as a result of the condensation of the vapor are deposited and removed through the trap 6. The attachment of the vertical cylinder 1 to the discharge pipe 5 of the fan 4 tangentially allows it to swirl zdushny flow which contributes to a better mixing of the air mixture and a more complete heat from steam pipe 2. 4 yl.

j The air intake device consists of a mixer in the form of a vertical cylinder 1, along the axis of which a heat exchanger 2 passes, made in the form of a steam pipe, a steam humidifier 3, a fan 4 and an air duct network. Cylinder 1 is installed after fan 4, which is connected to it with its injection pipe .5 tangentially. A humidifier 3 is located in the lower part of the vertical cylinder under the inlet of the discharge pipe 5. A condensate drain 6 is connected to the bottom of the vertical cylinder 1. The duct network consists of suction 7 and pressure 5 nozzles of the duct fan 8 supplying conditioned air to the fermentation compartment 9, the recirculation duct 10, the duct 11 of the outside air intake and the exhaust duct 12, Additional air heaters are internal heating pipes 13.

The device works as follows.

The air sucked in given proportions is -. the fan 4 from the fermentation compartment 9 through the recirculation duct 10 and from the room through the intake duct 11, through the suction nozzle enters the fan 4 and is fed tangentially into the vertical cylinder 1 through the discharge nozzle 5. Tangential flow of air flow ensures its twisting around the axis, as a result of this, when hit in. the compartment forms an expanding vortex, which makes it possible to completely blow its volume. When the vertical cylinder passes by the flow, the recirculation air and the outside air are mixed, it is heated by the steam pipe 2 and the resulting mixture is moistened with steam supplied through the steam humidifier 3.

The combination of a mixer and a heat exchanger in one unit reduces the outer surface and dimensions of the device, which reduces its losses and resistance to air passage, and twisting (twisting) the air flow promotes better mixing of the mixture and complete removal of heat from the steam pipe Z.

The steam humidifier 3 is located vertically below the discharge pipe 5j due to which the condensate droplets, not picked up by the air flow, are deposited and removed through the steam trap 6, Part of the small
