Description

The mobile apparatus of oil removing}

The present invention relates to an apparatus for washing oil and fat components remaining in a facility using liquid oxygen under high-pressure environmental conditions, and in particular, by removing the oil and fat by removing the oil and fat by drying the cleaning agent inside the equipment to be degreased, drying with hot nitrogen In addition, the present invention relates to a mobile degreasing apparatus that can be moved to perform degreasing and drying regardless of the position of the degreasing target equipment.

In general, in the case of the equipment using the liquid oxygen in the high pressure environment, there is a risk of triggering due to the action of high pressure and oxygen if the oil is left in the equipment. Therefore, it is safe to use the equipment which uses liquid oxygen in a high pressure environment after removing an oil-fat component.

Most conventional degreasing apparatuses are fixed and provided on the side of the degreasing target equipment. Such a degreasing device removes the risk of explosion by injecting a cleaning agent into a degreasing target to remove oil and fat from inside the degreasing target.

However, when the installation position of the degreasing target equipment is in a position where a separate degreasing apparatus cannot be installed or it is difficult to install the degreasing apparatus in terms of cost, there is a problem in safety by using the corresponding equipment without a special degreasing process. That is, since most degreasing apparatuses are very expensive equipment, it is difficult to install them wherever there is a degreasing target, and it is common to install only one near the center of a plurality of degreasing target facilities. Therefore, the degreasing target equipment far from the degreasing apparatus may be used without any special degreasing process.

In other words, the conventional degreasing apparatus is fixed at a certain position so that degreasing can not be performed when the degreasing target equipment is far away, and in some cases, the degreasing process is performed without degreasing the degreasing target equipment. There is a big problem.

The present invention has been made in order to solve the above problems of the prior art, it is possible to move while performing the drying using hot nitrogen gas while performing the degreasing by injecting the washing liquid to the degreasing target using the pressure of nitrogen It is an object of the present invention to provide a mobile degreasing apparatus capable of performing degreasing and drying regardless of the location of the equipment to prevent the explosion of the equipment.

The present invention for solving the above technical problem by using a nitrogen supplied from the nitrogen tank supplying the cleaning liquid to the degreasing target equipment to remove the holding component of the degreasing target equipment, and heating the nitrogen supplied from the nitrogen tank Then, the drying unit for supplying the degreasing target equipment to dry the inside, and the degreasing unit and the drying unit is installed, characterized in that consisting of a mobile truck provided with a moving wheel at the bottom.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

Mobile degreasing apparatus according to the present invention by using the nitrogen supplied from the nitrogen tank 10, as shown in Figures 1 and 2 by supplying a cleaning liquid to the degreasing target equipment (not shown) to remove the components of the degreasing target equipment And a degreasing unit for heating the nitrogen supplied from the nitrogen tank 10 and supplying it to the degreasing target facility and drying the inside thereof, and a degreasing unit and a drying unit installed therein, and a movable wheel 30 'at the bottom thereof. It is composed of a mobile cart 30 is provided.

The degreasing unit includes a detergent tank 12 in which a detergent is stored, a nitrogen tank 10 for supplying nitrogen to the detergent tank 12 to pressurize the detergent, and a detergent pumped from the detergent tank 12. A connector 15 connected to the degreasing target facility to be injected into the degreasing target facility, a first valve 16 installed in the nitrogen tank 10, and a second inlet of the detergent tank 12. A valve 17 and a third valve 18 provided at the outlet of the cleaning tank 12.

The drying unit 15 is connected to the degreasing target facility so that the heater 13 for heating the nitrogen from the nitrogen tank 10 and the hot nitrogen gas from the heater 13 can be supplied to the degreasing target facility. ), A fourth valve 19 provided at an inlet of the heater 13, a fifth valve 20 provided at an outlet of the heater 13, and hot nitrogen gas from the heater 13. It is composed of a temperature control unit 14 installed between the heater 13 and the fifth valve 20 to adjust the temperature.

Here, the degreasing unit and the drying unit share the nitrogen tank 10, the first valve 16, and the connector 15, and the first tank so that excessive pressure is not applied to the cleaner tank 12 or the heater 13. A relief valve 11 is installed behind the valve 16.

The mobile degreasing apparatus of the present invention configured as described above can reduce the risk of explosion of the degreasing target equipment since it is possible to perform a drying operation while removing the oil component in the degreasing target equipment regardless of the position of the degreasing target equipment.

The moving wheel 30 is moved to the place where the object to be degreased using the moving wheel, and then the connector 15 is connected to the object to be degreased. Thereafter, the first valve 16, the second valve 17, and the third valve 18 are opened, and the fourth valve 19 and the fifth valve 20 are blocked to remove nitrogen from the nitrogen tank 10. It is supplied to the cleaning tank through the first valve 16 and the second valve 17. When nitrogen is supplied to the cleaning tank 12, the cleaning agent is pressurized by the pressure of nitrogen. Since the third valve 18 is opened, the cleaning agent is injected into the degreasing unit through the connector 15. Therefore, the fat or oil remaining in the degreasing target equipment is completely removed.

Thereafter, when the second valve 17 and the third valve 18 are blocked and the fourth valve 19 and the fifth valve 20 are opened, nitrogen from the nitrogen tank 10 is supplied to the heater 13. . The heater 13 heats nitrogen to make hot nitrogen gas, and the hot nitrogen gas is supplied into the degreasing target facility through the fifth valve 20 and the connector 15 which are opened, and remains in the facility. The degreasing liquid is dried. At this time, the temperature control unit 14 detects the temperature of the hot nitrogen gas from the heater by a thermometer to change the temperature of the nitrogen gas so that the appropriate drying temperature.

Of course, the pressure of the nitrogen from the first valve 10 is inspected by a pressure gauge (11 '). The relief valve 11 'adjusts the pressure of nitrogen to a predetermined pressure range so that excessive pressure is supplied to the cleaning tank 12 or the heater 13 so that the device is not damaged. In addition, a thermometer is also installed on the side of the temperature control unit 14 to precisely control the temperature of the nitrogen gas discharged.

As described above, since the mobile degreasing apparatus of the present invention can perform degreasing and drying regardless of the installation position of the degreasing target equipment, there is an advantage of preventing the explosion due to the residual maintenance of the degreasing target equipment.
