Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a drying device, and more particularly to a device for drying foods, luxury goods, etc. with hot air using exhaust heat from an internal combustion engine that drives a generator.

Generally, on offshore fishing boats or on remote islands, electricity is not available, so food and luxury goods manufacturing equipment is operated using electricity from generators driven by internal combustion engines. There is.

2. Description of the Related Art In recent years, with the trend toward energy conservation, drying devices that use exhaust heat from internal combustion engines to dry foods, luxury goods, and the like with hot air have come into use.

Such drying equipment cannot directly send the exhaust gas from the internal combustion engine to the drying chamber due to the hygiene of the food and its nature, which dislikes foreign odors. , and is configured to apply exhaust heat through a heat exchanger.

However, the amount of heat obtained from the exhaust heat of the internal combustion engine and the amount of heat required for drying do not necessarily match, and the former amount of heat is generally insufficient compared to the latter. In addition, the dried air exhausted from the drying chamber has conventionally been directly released into the atmosphere, but this has had problems such as containing a large amount of moisture and having a strange odor.

The present invention was developed in view of the above-mentioned problems, and its purpose is to make the air discharged from the drying chamber join the exhaust pipe of the internal combustion engine upstream of the heat exchanger, and to A combustion chamber equipped with a burner is interposed in the exhaust pipe line between the heat exchanger and the burner, and the operation is controlled so that the air sent to the drying chamber has a predetermined amount of heat. The drying method enables the fresh air to be constantly heated to have the required amount of heat, as well as the secondary combustion of the exhaust gas of the internal combustion engine, the recovery of heat from the air discharged from the drying chamber, and the deodorization of the air. We are here to provide you with the equipment.

Hereinafter, one embodiment of this invention will be described in detail with reference to the drawings.

In the figure, 1 is an internal combustion engine such as a diesel engine that drives a power generation 2 that supplies electricity to manufacturing equipment for food products, luxury goods, etc. The exhaust gas from this internal combustion engine 1 is passed through an exhaust pipe 4 with a heat exchanger 3 interposed therein. As time passes,
The air is discharged into the atmosphere by a blower 5 installed downstream of the heat exchanger 3. The heat exchanger 3 is for imparting exhaust heat from the internal combustion engine 1 to fresh air sent through an air supply pipe line 8 equipped with an air blower 7 to a drying chamber 6 for drying foods and the like with hot air. The air discharged from the drying chamber 6 after drying the food, etc. is
It is connected to the exhaust pipe 4 of the internal combustion engine 1 via an exhaust pipe 9 upstream of the heat exchanger 3 .

Drying chamber 6 in the exhaust pipe line 4 of the internal combustion engine 1
A combustion chamber 11 containing a burner 10 is interposed between the confluence point with the exhaust pipe line 9 and the heat exchanger 3.
The fuel tank 14 is connected to the fuel tank 14 via an oil pipe line 13 that is connected to the fuel tank 14 . The flow rate regulator 12 controls the temperature of the air supply pipe 8 downstream of the heat exchanger 3 to operate the burner 10 so that the air supplied to the drying chamber 6 always has the required amount of heat. It is configured to be controlled based on the output signal of the detector 15.

With the above configuration, the fresh air sent to the drying chamber 6 for foods, etc. is heated by the exhaust heat of the internal combustion engine 1 via the heat exchanger 3, but if this air has less than the required amount of heat, The burner 10 in the combustion chamber 11 increases or decreases the amount of fuel from the fuel tank 14 using the flow rate regulator 12 controlled based on the signal from the temperature sensor 15, and the fuel is mixed with the exhaust gas from the internal combustion engine 1 and dried. In the air-fuel mixture with the exhaust gas from the chamber 6, secondary combustion is performed to raise the temperature of the exhaust gas to provide the required amount of heat.

Note that if the capacity of the burner 10 is made sufficiently large, it is possible to continue drying foods, etc. even if the internal combustion engine is stopped due to a failure or the like.

As described above, the present invention provides a device in which exhaust heat from an internal combustion engine that drives a generator is applied to fresh air delivered to a drying chamber for foods, etc. via a heat exchanger. merging the air discharged from the heat exchanger with the exhaust pipe of the internal combustion engine upstream of the heat exchanger, and interposing a combustion chamber equipped with a burner in the exhaust pipe between the merging point and the heat exchanger, The burner is connected to a fuel tank via a flow rate regulator, and the flow rate regulator is controlled by an output signal of a temperature sensor attached to an air supply pipe to a drying chamber downstream of the heat exchanger. Therefore, the fresh air supplied to the drying chamber can always have the required amount of heat. Further, it is possible to realize secondary combustion of the exhaust gas of the internal combustion engine, heat recovery from the exhaust gas from the drying chamber, and deodorization of the exhaust gas.
