The present invention relates to a device for preventing the odor of the petroleum burner, and in more detail, by installing an air recovery pipe in the middle of the primary air input pipe installed on one side of the vaporization chamber to filter the residual gas back to the inside of the vaporization chamber during the extinguishing By releasing to the outside after, the odor generating device of the petroleum combustor that can prevent the odor generated by the unburned gas.

In general, the combustion method of a petroleum combustor using liquid fuel is divided into hydraulic oil atomization type, rotary atomization type, and bunsen type. First, the hydraulic oil atomization type is installed with a heat transfer heater outside the vaporization chamber of the vaporizer. It refers to the combustion of the liquid fuel introduced through the vaporization in the gaseous state due to the internal heat inside the vaporization chamber, and the rotary atomization type is the same as that of the hydraulic transport atomization type, but the diffuser in the center of the vaporization part inside the vaporizer. By means of installing and rotating the liquid fuel flowing through the oil pipe connected to the electronic pump atomized in the diffuser and sprayed, and then evaporated in the gas state by the heat of the inner wall of the vaporization unit. In addition, the Bunsen-type burner refers to a method in which a separate vaporizer is installed on one side of the burner to vaporize the fuel from the outside, and then the vaporized fuel is supplied into the burner by the operation of the solenoid valve and burned.

In particular, Figure 2 shows a conventional hydraulic oil atomization type petroleum combustor, the inner center of the vaporization chamber (2) provided for vaporizing the injected fuel, and one side of the vaporization chamber (2) primary air input pipe (8) and a fuel supply pipe 6 are respectively provided at the center thereof, and a preheating heater 10 for raising the internal temperature of the vaporization chamber 2 is provided at the upper outer side, respectively; On the upper side of the vaporization chamber (2) is installed a burner head (12) consisting of a burner head (14), a filter net (16), and a burner cap (18) in which the vaporized fuel vaporized in the vaporization chamber (2) is discharged and burned. do.

In the conventional hydraulic oil atomization type petroleum combustor configured as described above, during combustion, first, a power is supplied to a preheating heater 10 provided on the outer upper side of the vaporization chamber 2 to preheat the vaporization chamber 2, and then the electronic pump ( 22) and the blower fan 21 are operated to inject fuel and primary air into the vaporization chamber 2. The fuel and primary air introduced as described above are vaporized and mixed in the vaporization chamber 2 and then elevated to burner 12 to be burned.

However, when extinguishing the petroleum combustor that performs the combustion operation as described above, the blower fan 21 installed inside the electronic pump 22 and the blower duct 20 is stopped at the same time. Due to the inertia rotation, the fuel remaining in the fuel supply pipe 6 is discharged to the outside in an unburned state, and thus there is a problem of causing an odor.

Therefore, the present invention was invented to solve the above problems, the air recovery pipe is installed in the middle of the primary air input pipe installed on one side of the vaporization chamber, the exhaust blower and the filter is provided at the end of the air recovery pipe While installing the discharge duct, while installing the solenoid valve to block the pipes respectively, just below the air return pipe of the primary air input pipe and the middle of the air recovery pipe, the air remaining inside the vaporization chamber during the fire of the oil combustor It aims to provide a odor generating device of the petroleum burner that can prevent the generation of odor due to unburned gas by allowing it to be filtered and discharged at the same time.

In the present invention for achieving the above object, the vaporization chamber is provided with a primary air input pipe on one side, a fuel supply pipe connected to the electron pump in the center thereof, and a preheating heater is installed on the upper outside, respectively, the vaporization chamber In the upper side of the petroleum combustor is provided with a burner head, a filter net, a burner cap which is the combustion of the vaporized fuel vaporized in the interior of the vaporization chamber, the primary air input pipe is connected to the blowing duct; An air return pipe having a second solenoid valve installed in the middle of the primary air inlet pipe, and an exhaust duct having a filter part and an exhaust blower fan respectively installed at an end of the air return pipe; It is characterized in that the first solenoid bell is installed directly below the air return pipe of the primary air input pipe.
