Description

Technical Field

[0001] This invention relates to the field of water treatment, and more particularly to a protein skimmer. Background Technology

[0002] A protein skimmer is a device that uses the surface tension of air bubbles in water to separate fine dirt and organic molecules.

[0003] The prior art protein separator uses a straight pipe to accumulate small bubbles, which reduces the water content of the small bubbles and generates large bubbles with high tension, thus reducing the final water content of the foam. for example: CN202010733764.7 Easily adjustable protein separator CN202122062953.9 Protein separator for large-scale aquaculture This approach has the following technical problems: Problem 1: The need for a specific type of pipe leads to high manufacturing costs.

[0004] Problem 2: The water removed by the upper bubble is caught by the lower bubble, resulting in low dehydration efficiency. This not only wastes energy but also requires users to carefully adjust the pipe pressure for normal use, making it inconvenient.

[0005] Question 3: The working times for bubbling and dehydration conflict with each other, resulting in low time efficiency and slow speed. Summary of the Invention

[0006] To address the above problems, the present invention provides the following technical solution.

[0007] A protein separator that excels in the following ways: It includes the upper pipe (H1), the lower pipe (H2), the bubble stacking pipe (D1), and the dehydration pipe (S1). The upper tube (H1) is higher than the lower tube (H2); The lower pipe (H2) has an inlet (H2-JK) and an outlet (H2-CK); The lower end of the bubble stack tube (D1) is connected to the lower tube (H2), and the connection point is located between the inlet (H2-JK) and the outlet (H2-CK); The lower end of the dehydration pipe (S1) is connected to the lower pipe (H2), and the connection point is located between the lower end of the bubble stacking pipe (D1) and the outlet (H2-CK); One end of the upper pipe (H1) is connected to the upper end of the bubble stack pipe (D1), and the other end of the upper pipe (H1) is the discharge end (H1-P). The upper end of the dehydration pipe (S1) is connected to the upper pipe (H1), and the connection point is located between the upper end of the bubble accumulation pipe (D1) and the discharge end (H1-P). The upper end of the dehydration pipe (S1) is lower than the top of the cavity of the upper pipe (H1) at the connection point. The upper pipe (H1) and the lower pipe (H2) both have a horizontal span.

[0008] Furthermore: the upper tube (H1) and the lower tube (H2) are round tubes.

[0009] Furthermore: the upper pipe (H1) and the lower pipe (H2) are PVC pipes.

[0010] Furthermore: the bubble tube (D1) and the dehydration tube (S1) are reducing tubes with a larger diameter at the bottom and a smaller diameter at the top.

[0011] Furthermore: the bubble tube (D1) can be a straight tube or a bent tube.

[0012] Furthermore: the dehydration pipe (S1) can be a straight pipe or a bend.

[0013] Furthermore: the bubble tube (D1) and the dehydration tube (S1) are arranged in parallel.

[0014] Furthermore: the upper tube (H1) and the lower tube (H2) are placed horizontally.

[0015] Furthermore: the number of bubble tubes (D1) is greater than 1.

[0016] Furthermore: the number of bubble tubes (D1) is equal to 1.

[0017] Furthermore: the number of dehydration tubes (S1) is greater than 1.

[0018] Furthermore: the number of dehydration tubes (S1) is equal to 1.

[0019] Working principle: When in use, the upper pipe (H1) should be above the water level line (SWX), and the lower pipe (H2) should be below the water level line (SWX). The gas-liquid mixture (SQ) enters from the inlet (H2-JK). The bubbles rise and preferentially enter the bubble stack tube (D1). Therefore, the gas pressure in the bubble stack tube (D1) is higher than that in the dehydration tube (S1). After foam is generated, the foam enters the upper tube (H1), causing the pressure in the bubble stack tube (D1) to be transmitted to the upper end of the dehydration tube (S1). This makes it difficult for the foam in the dehydration tube (S1) to be discharged, forming a foam plug in the dehydration tube (S1). When the foam generated by the foaming tube (D1) passes through the upper end of the dehydration tube (S1), due to gravity, the lower foam has a higher water content and the upper foam has a lower water content. The lower foam merges with the foam plunger under the action of gravity, and the water in the foam flows down along the foam plunger to achieve dehydration. Therefore, the foam becomes relatively dry after passing through the upper end of the dehydration pipe (S1). Beneficial effects

[0020] In this invention, the bubble stacking pipeline and the dehydration pipeline are separated, so the dehydrated water will not be received by subsequent bubbles, thus resulting in high dehydration efficiency and low energy waste.

[0021] This invention has low requirements for the shape of the pipe and low manufacturing cost.

[0022] The dehydration principle of this invention results in low requirements for the incoming gas-liquid mixture, greatly reducing the difficulty of adjustment, and almost eliminating the need for adjustment.

[0023] The working method of this invention separates the bubble stacking direction and the flow direction of the extracted water to form a working production line. The working times do not conflict, so this invention has higher time efficiency and faster speed.

[0024] In summary, this invention has high energy efficiency, low cost, easy to use, and faster processing speed. Attached Figure Description
