Description

Technical Field

[0001] The invention belongs to the field of chemical industry, and in particular relates to a bubble elimination and separation device. Background Art

[0002] In the process of refined salt production, in order to improve the quality of refined salt products, the raw brine (salt field brine, concentrated seawater) needs to be purified. At present, there are two methods of treatment: physical purification and chemical purification. Among them, physical purification methods include natural sedimentation, sand filtration, fiber filtration, membrane filtration, flotation filtration, bag filtration, etc., and chemical methods include flocculation sedimentation, alkaline precipitation, etc. As a green sea salt production, chemical purification is not desirable. The physical purification method is also divided into coarse filtration and fine filtration. At present, the industry mostly uses coarse filtration (sand filtration, flotation filtration) to save production costs. As a commonly used method in the industry, flotation filtration has its own process defects: there are more foams, especially under outdoor conditions, salt-containing foam splashes and overflows, and the on-site environment is bad. In order to improve the on-site environment, it is necessary to treat the foam secondary to prevent the foam from overflowing, recover part of the brine, and improve the utilization rate of raw materials. As a salt-making enterprise, brine is cheap, and there are few ways to study and treat it. Foam treatment is necessary in the organic chemical material industry, and the methods used are mostly chemical reagent defoaming, and then separation, and the investment and operation costs are high. Summary of the invention

[0003] In view of this, the present invention aims to provide a bubble elimination and separation device.

[0004] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0005] A bubble elimination and separation device comprises an outer sleeve and a central defoamer, wherein the outer sleeve is sleeved on the outer side of the central defoamer;

[0006] The central defoamer comprises an exhaust pipe, on which a plurality of defoaming umbrellas are arranged from top to bottom, and a plurality of exhaust holes are arranged on the exhaust pipe, and the exhaust holes are located on the inner side of the defoaming umbrella. The upper and lower parts of the outer sleeve are connected by flanges.

[0007] Furthermore, the number of the exhaust holes is greater than or equal to the number of the defoaming umbrellas.

[0008] Furthermore, each defoaming umbrella has 1-5 exhaust holes on its inner side. The exhaust holes are used to increase the exhaust outlet area and reduce the weight of the exhaust pipe itself, making the overall equipment lighter and more convenient to adjust in height.

[0009] Furthermore, the shape of the exhaust hole is an elliptical structure. The bubbles are squeezed by the defoaming umbrella during the process of flowing down with the liquid, and the bubbles burst. The gas must be separated from the liquid to play a defoaming role. It is precisely because the exhaust hole is opened on the inner side of the defoaming umbrella that the liquid flows down under the action of gravity, and the gas is squeezed and discharged from the air hole under the umbrella into the exhaust pipe, and finally discharged from the top of the exhaust pipe to form a gas-liquid separation system.

[0010] Furthermore, the longitudinal section of the defoaming umbrella is an isosceles trapezoidal structure, and the angle between the lower base and the waist of the isosceles trapezoidal structure is 50-70 degrees. According to the falling speed of the liquid and the overall height of the outer sleeve, a large angle has a small resistance to the liquid, and the height of the conical tube needs to be increased under the same processing capacity; a small angle has a large resistance to the liquid, and the feed speed needs to be increased (the feed pump head increases).

[0011] Preferably, the angle between the lower base and the waist of the isosceles trapezoidal structure is 60-70 degrees.

[0012] Furthermore, the upper part of the outer sleeve is provided with a clear liquid inlet and a raw liquid inlet. The clear liquid inlet is used to flush when solid materials in the raw liquid block the gap between the defoaming umbrellas.

[0013] Furthermore, a hanger is provided on the upper part of the outer sleeve, and a bracket is provided on the lower part, and the central defoamer is fixed on the outer sleeve through the hanger and the bracket. The hanger and the bracket are flange-connected to the outer sleeve, and the hanger and the bracket are threaded or welded to the exhaust pipe, which is convenient for later maintenance and inspection of the equipment.

[0014] The size and quantity of bubbles in the liquid during production are not fixed. In order to improve the applicability of the equipment, it is necessary to have adjustable performance to increase its environmental adaptability.

[0015] An adjustment handle is arranged on the upper part of the exhaust pipe to facilitate threaded adjustment of the position of the exhaust pipe.

[0016] During the production process, the central defoamer is adjusted up and down according to the size and number of bubbles, so as to adjust the gap between the defoaming umbrella and the outer sleeve (adjusting up to increase the gap can increase the processing volume; adjusting down to reduce the gap can increase the bubble processing accuracy and make the bubbles in the liquid fewer and smaller).

[0017] Furthermore, a support tube is arranged on the bracket, the exhaust pipe is placed in the support tube, and a plurality of reinforcing ribs are arranged between the support tube and the bracket.

[0018] Preferably, the number of the reinforcing ribs is 3. The bracket uses the three-point support stability principle to reduce the processing difficulty, reduce the blocking area of ​​slurry discharge, and increase the stability performance. Its support angle is based on the same principle as the defoaming umbrella angle, using a 60° equilateral triangle angle, which increases the range of material selection (materials of general strength can meet the support capacity).

[0019] The outer sleeve is provided with an observation mirror port, which is convenient for observing the blockage of the gap of the defoaming umbrella.

[0020] The outer sleeve and the central defoamer are both made of 316L stainless steel.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] In the process of purifying brine in the production of refined salt, after using the bubble elimination and separation device described in the present invention, the brine containing bubbles can achieve foam elimination, the brine with entrained foam is recovered, the production site environment is improved, and the environmental protection and equipment corrosion problems are solved.

[0023] The bubble elimination and separation device described in the present invention is also used in the gas-liquid separation process of salt discharge mother liquor and centrifuge mother liquor. The mother liquor barrel no longer overflows due to foam problems, causing the production site to be dirty and messy. The problem of the mother liquor pump running empty during discharge is improved, and the operation cycle of the mother liquor pump is extended. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0039] like Figure 1-8As shown, a bubble elimination and separation device comprises an outer sleeve 1 and a central defoamer 2, wherein the outer sleeve 1 is sleeved on the outer side of the central defoamer 2; the central defoamer 2 comprises an exhaust pipe 21, wherein the exhaust pipe 21 is provided with 8 defoaming umbrellas 22 from top to bottom, and the exhaust pipe 21 is provided with a plurality of exhaust holes 211, wherein the exhaust holes 211 are located on the inner side of the defoaming umbrella 22. The upper and lower parts of the outer sleeve 1 are connected by flanges. There are 3 exhaust holes 211 on the inner side of each defoaming umbrella 22. The exhaust holes 211 are provided to increase the exhaust outlet area and to reduce the weight of the exhaust pipe 21 itself, so that the overall equipment is lighter and the height adjustment is convenient.

[0040] The exhaust hole 211 is in an elliptical structure. When the bubbles flow down with the liquid, they are squeezed by the defoaming umbrella 22, and the bubbles burst. The gas must be separated from the liquid to play a defoaming role. It is precisely because the exhaust hole 211 is opened on the inner side of the defoaming umbrella 22 that the liquid flows down under the action of gravity, and the gas is squeezed and discharged from the air hole under the umbrella into the exhaust pipe 21, and finally discharged from the top of the exhaust pipe 21 to form a gas-liquid separation system.

[0041] The longitudinal section of the defoaming umbrella 22 is an isosceles trapezoidal structure, and the angle between the lower base and the waist of the isosceles trapezoidal structure is 60 degrees. According to the falling speed of the liquid and the overall height of the outer sleeve 1, a large angle has a small resistance to the liquid, and the height of the conical tube needs to be increased under the same processing volume; a small angle has a large resistance to the liquid, and the feed speed needs to be increased (the feed pump head increases).

[0042] The upper part of the outer sleeve 1 is provided with a clear liquid inlet 11 and a liquid stock liquid inlet 12. The function of the clear liquid inlet 11 is to flush when the solid material in the stock liquid blocks the gap of the defoaming umbrella 22.

[0043] The upper part of the outer sleeve 1 is provided with a hanger 3, and the lower part is provided with a bracket 4. The central defoamer 2 is fixed to the outer sleeve 1 through the hanger 3 and the bracket 4. The hanger 3 and the bracket 4 are flange-connected to the outer sleeve 1, and the hanger 3 and the bracket 4 are threaded or welded to the exhaust pipe 21. It is convenient for the later maintenance and inspection of the equipment. The size and number of bubbles in the slurry during production are not fixed. In order to improve the applicability of the equipment, it is necessary to have adjustable performance to increase its environmental adaptability. During the production process, the central defoamer 2 is adjusted up and down according to the size and number of bubbles, so as to adjust the gap between the defoaming umbrella 22 and the outer sleeve 1 (upward adjustment to increase the gap can increase the processing volume; downward adjustment to reduce the gap can increase the bubble processing accuracy and make the bubbles in the liquid fewer and smaller.).

[0044] An adjustment handle is provided on the upper part of the exhaust pipe 21 to facilitate threaded adjustment of the position of the exhaust pipe 21. An observation mirror port is provided on the outer sleeve 1 to facilitate observation of the blockage of the gap of the defoaming umbrella 22. The outer sleeve 1 and the central defoamer 2 are both made of 316L stainless steel.

[0045] The bracket 4 is provided with a support tube 41, the exhaust pipe 21 is placed in the support tube 41, and three reinforcing ribs 42 are provided between the support tube 41 and the bracket 4. The bracket 4 uses the three-point support stability principle to reduce the processing difficulty, reduce the blocking area of ​​liquid discharge, and increase the stability performance. Its support angle is based on the same principle as the angle of the defoaming umbrella 22, and adopts a 60° equilateral triangle angle, which increases the range of material selection (materials of general strength can meet the support capacity).

[0046] When brine passes through the device, bubbles are separated, the liquid phase passes from top to bottom, and the gas phase is separated and discharged from the exhaust pipe 21 from bottom to top. The amount of separated brine and the bubble separation effect are controlled by adjusting the upper and lower positions of the exhaust pipe 21, and the operation of the equipment is observed to determine the adjustment range of the central pipe.
