Abstract

The utility model discloses a liquid soluble oxygen increasing device. The back of a soleplate is connected with a vent pipe, and a supporting plate is fixed on the soleplate. An ejector which is concentric with the vent pipe is fixed on the supporting plate. A distributor which is provided with an inner and an outer cylinders is fixed on the upper opening of the ejector, and vertical blades which are connected are uniformly distributed between the inner and the outer cylinders. The utility model is arranged in liquid, air or oxygen is pressed from the vent pipe, and the liquid and the gas enter the ejector together and come back to a container from the upper opening of the distributor. The utility model has the advantages of extended contact time and enlarged contact area for the liquid and the oxygen, increased soluble oxygen amount, convenient cleaning and use, and low failure rate. The utility model is widely used for increasing the amount of soluble oxygen at the time of submerged fermentation for good oxygen, sewage treatment for the good oxygen, etc.

Description

Liquid dissolved oxygen intensifier

The utility model belongs to the liquid dissolved oxygen and strengthens equipment.

In the aerobic fermentation process of microbial fermentation, dissolve in more oxygen in the mash for making, now many with leaving a plurality of holes or nozzle on a kind of ring pipe, pacify the dissolving device of a breather pipe in the pipe side, during use, dissolving device is put into mash, by breather pipe air or pure oxygen are sent in the ring pipe, the a plurality of eyelets of gas on ring pipe enter mash, thereby have increased the contact-making surface of oxygen and liquid, and the dissolved oxygen amount of liquid is increased.The shortcoming of this dissolving device is that oxygen is fed in the ring pipe, and oxygen enters in the localized liquid in the hole from it, can not produce the liquid systemic circulation, and the liquid oxygen contact-making surface is little, and dissolved oxygen amount is undesirable; The interior easily deposit dirt of ring pipe is stopped up eyelet, and is difficult to cleaning after stifled in addition, dissolved oxygen is normally carried out, thereby influence next step production, even cause the failure of overall process production because of cleaning dirty microbiological contamination.

The purpose of this utility model is, designs a kind of dissolved oxygen amount that can increase in the liquid, and low, the easy to operate liquid dissolved oxygen intensifier of fault rate in using.

For reaching this purpose, the technical solution of the utility model is, penetrate the breather pipe of base plate in the base plate back side of bracing frame installation one, be fixed on be fixed with on the gripper shoe above the base plate with the concentric end size of breather pipe on tubaeform ejector, the ejector top is fixed with distributor, it is suitable for reading that the outer cylinder of distributor is connected on ejector, and central part has the inner cylinder concentric with the bottom ejector, has the vertical blade that is uniformly distributed along the circumference that it is linked to each other between inside and outside cylinder.

For further increasing dissolved oxygen amount, can also add one again to the concentric ejector of two-stage on ejector top.

During use, this device is put into the liquid that needs dissolved oxygen, its breather pipe stretches out beyond the container of holding liquid, and liquid level with the end opening submergence of ejector or whole submergence wherein it on; Air or pure oxygen are fed breather pipe inject ejector under certain pressure, form negative pressure around the gas of high flow rate, liquid in the container is assembled with oxygen in air-flow and is contacted, the blade of the distributor of process ejector end face is discharged from periphery suitable for reading equably and is returned to container, gas constantly feeds, and liquid is then constantly done to come in and go out in this device thereupon and circulated and a large amount of bubbles of generation in liquid.

Because oxygen is pressed into ejector from the breather pipe of this device bottom after, gas produces swabbing action to liquid, make oxygen and liquid simultaneously by ejector to distributor, again from container is overflow back at the top of distributor, liquid and oxygen together circulation timei long, bubble that forms and liquid contact surface are long-pending big, so dissolved oxygen amount height, after tested, its dissolved oxygen amount of dissolved oxygen intensifier with the one-level ejector increases by 5-10% dissolved oxygen amount approximately than existing circle shaped tube type dissolving device, if during with the two stage jet device, dissolved oxygen amount also can improve; Because this device do not have aperture and dead angle, the dirt on it can be removed totally in the lump when scrubbing container and be discharged to outside the container, makes things convenient for so use to clean, and dailyly can not produce fault effects production.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the front view of the liquid dissolved oxygen intensifier of band one-level ejector;

Fig. 2 be among Fig. 1 A-A to the vertical view of direct current distributor;

Fig. 3 is the front view of the liquid dissolved oxygen intensifier of band two stage jet device;

Fig. 4 be among Fig. 3 B-B to the vertical view of rotational flow distributor.

Among Fig. 1, the back side at the base plate 3 of a bracing frame, be welded with the breather pipe 1 that sees through base plate, this pipe can be a straight tube, it also can be the not isometrical pipe of the band air nozzle 2 that inwardly contracts at the position that combines with base plate 3, the top center with breather pipe of base plate 3 is that basic point is radiation and is vertically fixed with at least 3 gripper shoes 4 in uniform way, the ejector 5 that little flare is gone up at the end greatly is fixed on the gripper shoe 4, the top of ejector 5 is fixed with the distributor concentric with it 6, the urceolus circle 6.1 of this distributor is enclosed within the top of ejector 5, inner cylinder 6.3 is positioned at the center of distributor 6, has vertical uniform blade 6.2 to connect between inside and outside cylinder; For contact area and the time that increases oxygen and liquid, outer cylinder 6.1 can be made truncated cone-shaped, blade 6.2 is vertically to distribute to form direct current distributor 6 (referring to Fig. 2), and perhaps outer cylinder is cylindrical, and blade arranged askew is in the shape of a spiral formed rotational flow distributor 8 (referring to Fig. 4).

Among Fig. 2, for further strengthening the dissolved oxygen amount that uses this device, also can be at the top of ejector 5, on gripper shoe, increase secondary jets device 7 again, at this moment, the distributor 6 on ejector 5 tops is that the outer cylinder composition direct current distributor of vertical blade truncated cone-shaped and the distributor on secondary jets device 7 tops are formed rotational flow distributor 8 by the blade 8.2 of inner cylinder 8.3 and outer cylinder 8.1 and the spiral arranged askew between them.If air or the pure oxygen pressure sent into from breather pipe 1 allow, ejector increases progression again, still is within the utility model protection domain.

This device increases the dissolved oxygen amount of liquid except that being used for the aerobic submerged fermentation of brewing industry, to environmental protection aspect sewage aerobic handle and freshwater aquiculture etc. other need increase the occasion that the liquid dissolved oxygen puts and all can use.
