Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a small portable incinerator for processing used waste solvents.

The amount of waste solvents such as benzene and methyl isobutyl ketone generated in schools, research laboratories, laboratories, analysis rooms, etc. is 1 to 3 (3 to 5 at most) per month.
In many cases, the amount is too small to be purified and reused as a solvent, and even if commercially available waste oil incineration equipment is purchased and incinerated, the waste solvent generated in small amounts over a long period of time is stored. Since waste solvents, which are flammable substances, must be incinerated after a certain amount has been collected, there are issues with ensuring safety, the cost of incineration equipment, and operating rates when storing waste solvents that are flammable for a long period of time. Currently, there is a problem in how to dispose of waste solvents.

The object of the present invention is to provide a small-sized portable waste solvent incineration device that can process the waste solvent generated in small amounts each time and can be moved as needed.

That is, the present invention has a regulator that adjusts the pressure and flow rate of compressed air and auxiliary combustion gas, a burner to which the compressed air and auxiliary gas are supplied via the regulator, and a thin tube connected to the center of the burner. The present invention relates to a small-sized portable waste solvent incineration device that includes a waste solvent storage tank and a washer that uses a pump to suction and clean combustion gas generated by a burner.

Next, one embodiment of the present invention will be described below with reference to the drawings.

In the figure, 1 is a compressor, and 2 is a gas cylinder filled with auxiliary combustion gas such as acetylene, propane, hydrogen, etc., both of which are placed below the device or connected to the device by piping from the outside. The pressure and flow rate of the compressed air and auxiliary combustion gas obtained from the compressor 1 and the cylinder 2 are controlled by the regulator 3, respectively, and the air is sent to the burner 5 disposed upward. Reference numeral 18 denotes a storage tank disposed at the lower part of the apparatus to store the waste solvent 7, and is connected to the burner 5 through a thin tube 4.

In the burner 5, as shown in FIG.
The auxiliary combustion gas from the compressor 1 and the compressed air from the compressor 1 are separately blown into the interior through supply pipes 15 and 16, respectively, and the negative pressure generated in the burner nozzle 17 at the upper end by the compressed air communicates the tip with the center of the nozzle 17. The waste solvent 7 is sucked through the narrow tube 4, sprayed from the nozzle 17, and combusted together with the auxiliary combustion gas. A valve 6 is provided in the middle of the thin tube 4, and the flow rate (amount of suction) introduced into the burner 5 is adjusted depending on the degree of combustibility of the waste solvent 7.

The combustion gas of the waste solvent 7 from the burner 5 is transferred to the burner nozzle 1 by the operation of the suction pump 9 in this device.
Collected in a hood 8 that opens downward directly above 7,
Gas scrubber 1 filled with cleaning liquid via piping 20a
After being blown in from the lower part of 1 and purified, it is introduced into the cushion tank 10 via the piping 20b, and is discharged into the atmosphere from the discharge pipe 19 by the suction pump 9. 12 is an air vent valve provided in the washer 11 which is opened when the suction pump 9 stops; 13 is a vent valve for exchanging cleaning liquid in the washer 11; and 14 is a drain vent valve for the cushion tank 10. be.

The gas cleaning liquid in the cleaning device 11 may be water, but various aqueous solutions such as a caustic soda aqueous solution may be used depending on the components of the waste solvent 7. Further, the waste solvent 7 may be introduced into the burner 5 by forcibly injecting it by a pump instead of by suction using the negative pressure of compressed air at the nozzle 17. Furthermore, wheels 21 can be attached to the pedestal on which the device is mounted to facilitate movement.

According to the present invention, it is possible to easily dispose of waste solvents, which are difficult to dispose of in the past because they are generated in small quantities, each time, and it is no longer necessary to store highly flammable waste solvents for a long period of time, unlike in the past. Safety issues associated with this can be resolved. In addition, since the entire device is compact and portable, it does not take up much space and can be easily moved to the required location for economical and efficient processing.

This device can process not only waste solvents but also general waste oils that are generated in small quantities.In addition, in laboratories and analysis rooms, gaseous fuels such as acetylene and hydrogen and compressed fuels can be used for atomic absorption spectroscopy and other purposes. Since air is often used, there is the advantage that if it is connected to this device, it can be used at low cost without requiring any other special equipment.
