Abstract

PROBLEM TO BE SOLVED: To enable a purifier to easily purify an organic waste liquid indoors by installing a filter packed with adsorbent inside so that a feed liquid can pass through it by gravity and adjusting the flow rate of the liquid passing through the filter by a flow adjusting means. SOLUTION: A filter consists of plural cartridges 5 in the shape of a cylinder with a bottom piled up in the vertical direction providing gaps each other in which an adsorbent is packed respectively. Since the cartridges 5 are piled up and provided with the gaps each other, while feed liquid passes, the spaces in the cartridges 5 are kept at atmospheric pressure. Therefore, the feed liquid passes through each of the cartridge 5 by gravity at a stable velocity. Then, since liquid outflow ports 51 are provided in the plural places of the bottom surface of the cartridge 5 and can be opened and closed so as to attach and detach screwed type covers, by changing the ratio of the number of openings to the number of the closings of the liquid outflow ports 51 corresponding to kinds and concentrations of the liquid, the flow rate can be adjusted.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a desktop type organic waste liquid purifying apparatus.

[0002]

2. Description of the Related Art Conventionally, organic solvent waste liquid discharged in a laboratory or the like has been treated as waste oil of industrial waste by a waste oil processing company. It is possible to regenerate by a known distillation method, but the regenerating purity is low due to the azeotropic action, and the equipment is complicated and expensive, so it is not suitable for use in a laboratory. Because.

[0003]

However, in recent years, recycling has been demanded from the viewpoints of environmental pollution prevention and effective use of resources. Therefore, an object of the present invention is to provide an apparatus capable of easily purifying an organic waste liquid indoors.

[0004]

In order to achieve the object, an organic waste liquid purifying apparatus according to the present invention comprises a filtration filter filled with an adsorbent so that a supply liquid can pass by its own weight, and a filtration filter. Flow rate adjusting means for adjusting the flow rate of the passing liquid.

[0005] The type and concentration of the organic waste liquid vary depending on the facility and the date of treatment. Therefore, it is not possible to sufficiently purify the liquid simply by bringing the liquid into contact with the adsorbent while flowing the liquid by its own weight as in a normal water purifier. Therefore, a means for adjusting the flow rate per unit time of the filter according to the type and concentration is provided, and thereby, purification is performed. In addition, since this apparatus passes a supply liquid through a filtration filter by its own weight, a liquid feeding apparatus such as a pump is not required.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The filtration filter comprises a plurality of bottomed cylindrical cartridges stacked with, for example, a gap therebetween in the vertical direction and each of which is filled with an adsorbent,
The flow rate adjusting means is, for example, a liquid outlet provided at a plurality of locations on the bottom surface of each cartridge so as to be opened and closed. Since the cartridges are stacked with a gap therebetween, the space in the cartridge is maintained at the atmospheric pressure during the passage of the supply liquid. Therefore, the supply liquid passes through each cartridge at its own weight and at a stable speed. Since the liquid outlet is provided on the bottom surface of the cartridge so as to be openable and closable, the flow rate may be adjusted by changing the ratio between the opening number and the closing number of the outlet according to the type and concentration of the liquid.

[0007] Further, since each of the plurality of cartridges is filled with the adsorbent, the adsorbent can be different for each cartridge. For example, the former adsorbent is activated carbon,
Alumina is used as the adsorbent in the latter stage, and the respective processes of decolorization in the former stage and dehydration in the latter stage can be continuously performed. In addition, when the same type of adsorbent is filled in the preceding and succeeding stages, the performance of the preceding adsorbent usually deteriorates first. Therefore, the first cartridge is discarded, the second cartridge is advanced to the first stage, and a new cartridge is introduced to the second stage. By doing so, the adsorbent can be completely used. In addition, the number of stages of the cartridge can be three or more, and the combination of the adsorbents can be various.

[0008] The filtration filter may be, for example, a bendable column, and the flow rate adjusting means may fix the curvature of the column. By bending the column and setting the curvature according to the type and concentration of the liquid, it is possible to flow at a flow rate suitable for the liquid. The filtration filter may be a simple column, and the flow rate adjusting means may be a cock provided at a lower end of the column. In this case, the flow rate is adjusted by the opening / closing degree of the cock.

【Example】

-Example 1-This is an example of the purification device of the present invention in which the filtration filter is a cartridge type. 1 is a perspective view of the purifying apparatus, FIG. 2 is a front view thereof, FIG. 3 is a right side view thereof, FIG. 4 is an exploded perspective view of a cartridge used in the purifying apparatus, and FIG. FIG.

The purifying apparatus 1 comprises a table 2, a liquid recovery box 3 placed under the table 2, and an outer cylinder 4 stacked and fixed on the table 2.
, Cartridges 5, 5 stacked in two stages inside the outer cylinder 4 on the base 2, and a storage tank 6 stacked on the cartridge 5 in the upper stage.

The liquid recovery box 3 has an opening 31 on the upper surface and a knob 32 on the front surface, and is of a drawer type. The cartridge 5 has a cylindrical shape with a bottom that extends slightly upward and has three downwardly projecting outlets 51, 51, 5 on the bottom surface.
1 is provided, and a screw-in type lid 52 can be attached to and detached from each outlet 51. A packing 54, which is made of rubber and has split grooves 53, 53 provided at two opposite positions, is fixed to the outer periphery of the lower portion of the cartridge 5. Therefore, when the upper cartridge 5 and the lower cartridge 5 are connected, they are in close contact with each other, and the inside and the outside of the lower cartridge 5 communicate with each other through the split groove 53. The cartridge 5 is filled with an adsorbent such as activated carbon and alumina powder. The storage tank 6 has a bottomed cylindrical shape and is stacked on the upper cartridge 5. A rubber packing 61 is also fixed to the outer periphery of the lower portion of the storage tank 6. However, unlike the packing 54, there is no split groove. A number of holes (not shown) through which the liquid passes are provided on the bottom surface of the storage tank 6.

When purifying the organic waste liquid using the purifier 1, the outlet 51 is fully opened in advance or one outlet 51 at the center or two outlets 5 on both sides depending on the nature of the waste liquid.

The waste liquid is poured from above and the lid 62 is closed. The waste liquid falls evenly into the upper cartridge 5 through the hole. Depending on the total amount of the waste liquid to be poured, the upper cartridge 5 becomes full, but since the packing 61 is fixed, it does not spill. The waste liquid that has fallen into the upper cartridge 5 is filtered and flows out from the outlet 51 to the lower cartridge 5. Since the inside and outside of the lower cartridge 5 communicate with each other by the dividing groove 53, the waste liquid falls at a stable speed. It is filtered again by the lower cartridge 5 and collected in the liquid collection box 3.

Example 2 This is an example of the purifying apparatus of the present invention in which a filtration filter is a column type which can be bent. FIG. 6 is a front view of the purification device of the present example, and FIG. 7 is a front view showing the same use state.
