[0015] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this utility model can be more easily understood and mastered. Attached Figure Description

[0016] Figure 1 This is a schematic diagram of the structure of this utility model;

[0017] The components include: 1. V-shaped baffle; 2. Herringbone baffle; 3. Herringbone baffle; 4. Ventilation manifold; 5. I-beam support; 6. Connecting support. Detailed Implementation

[0018] This utility model discloses a combined anaerobic tower three-phase separator, which belongs to the field of wastewater treatment.

[0019] like Figure 1 As shown, an anaerobic three-phase separator is provided, wherein the lower end of the ventilation pipe 4 is connected to the herringbone baffle 3, the herringbone baffle 3 and the figure-eight baffle 2 are connected by a connecting bracket 6, the lower end of the connecting bracket 6 is provided with an I-beam support 5, and the V-shaped baffle 1 is connected to the I-beam support 5.

[0020] The anaerobic three-phase separator comprises three baffles with different structures and a gas distribution pipe, the chevron baffle is an angle plate structure, the two sides of the cross section of the chevron baffle extend downward, the included angle formed by the intersection of the two sides is upward and connected with the gas distribution pipe, the two sides extend downward with the same length, forming an isosceles right triangle, the mutton baffle is perpendicular to the chevron baffle and arranged in parallel, located directly below the chevron baffle, connected by two connecting supports, forming a double-layer umbrella structure, the V-shaped baffle is arranged below the mutton baffle on both sides with a small gap, and the two V-shaped baffles are symmetrical structures. When the organic matter in the sewage reacts with the anaerobic bacteria in the tank body to generate biogas, the biogas carrying the flocculent sludge rises, part of it hits the lower part of the V-shaped baffle 1 of the anaerobic three-phase separator, and because there are the mutton baffle 2 and the chevron baffle 3 in the vertical direction, the unhit part will hit the lower part of the mutton baffle 2 and the chevron baffle 3 of the anaerobic three-phase separator in turn, the hit surface of the three baffles in the vertical direction increases the contact area of the biogas carrying the flocculent sludge and the anaerobic three-phase separator, thereby making the biogas and the flocculent sludge fully separated, improving the separation efficiency of the anaerobic three-phase separator, and realizing the function of the reflecting plate of the traditional three-phase separator.

[0021] The connecting support 6 connects the chevron baffle 3 and the mutton baffle 2, which improves the firmness of the combination;

[0022] The top end of the chevron baffle 3 is provided with a gas distribution pipe 4, the outlet end of the gas distribution pipe 4 is communicated with the gas main pipe of the tank body, the biogas separated by the V-shaped baffle 1, the mutton baffle 2 and the chevron baffle 3 is converged to the gas main pipe through the gas distribution pipe 4 and transported out of the tank body, ensuring that there is space left in the anaerobic three-phase separator, thereby making the biogas continuously separated and transported out of the tank body, avoiding the biogas remaining in the tank body, changing the pressure of the tank body, and thereby affecting the rising of the biogas carrying the flocculent sludge. In order to ensure the separation effect of the V-shaped baffle 1, the mutton baffle 2 and the chevron baffle 3, so that the sludge can smoothly slide through the gap without being retained, the angle formed by the two sides of the cross section of the mutton baffle 2 and the chevron baffle 3 is 90°, and the angle formed by the two sides of the cross section of the V-shaped baffle 1 is 45°.

[0023] For some sewage with good biochemical properties, the treatment load is high, the biogas production and the inflow are large, and the space occupied by the anaerobic three-phase separator part is certain, which causes the outflow velocity of the water gap of the anaerobic three-phase separator to be too large. In order to improve the effect of collecting gas, the number of the V-shaped baffle 1, the mutton baffle 2 and the chevron baffle 3 of the anaerobic three-phase separator is reduced, and the height of the three-phase separation zone is increased, and the flow gap of the V-shaped baffle 1, the mutton baffle 2 and the chevron baffle 3 is increased.

Although the present application has been described in detail with reference to the foregoing embodiments, modifications or equivalent replacements to the technical solutions described in the foregoing embodiments can be made by those skilled in the art, and the modifications or equivalent replacements shall fall within the scope of the present application.
