Obviously, the embodiments described below are only some of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the patent, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the patent.

[0029] As shown in Figure 1 The specific embodiment provides a skimming device for odor gas suction of a deaeration tank, which comprises a tank body, an exhaust port 10 is arranged at the upper portion of the tank body, the exhaust port 10 is used for being communicated with a fan, the inside of the tank body is divided into a skimming area 2 and an air inlet area 3 through a grid, the skimming area 2 is located at the upper portion of the air inlet area 3, the inside of the skimming area 2 is provided with scattered pile fillers, the scattered pile fillers adopt hollow polyhedral balls 7, and the air inlet area 3 is provided with an air inlet port 6, which can be communicated with the deaeration tank.

[0030] The specific embodiment plays the roles of hindering and disturbing flow by the hollow polyhedral balls 7 scattered in the skimming area 2, increases the gas turbulence degree, makes the foam carried in the suction odor gas break, thereby plays the role of trapping the foam, avoids the foam carried in the odor gas from entering the fan, and further avoids the mixed impurities such as sludge in the foam from entering the fan to cause adverse effects, greatly reduces the frequency of shutdown maintenance.

[0031] As shown in Figure 2 In the specific embodiment, the hollow polyhedral ball 7 can adopt the following specific structure: the hollow polyhedral ball 7 comprises coaxially arranged upper support rings 701, middle support rings 702 and lower support rings, at least ten petals 703 are arranged between the upper support rings 701 and the middle support rings 702 and between the middle support rings 702 and the lower support rings, the upper and lower multiple petals 703 are arranged alternately, and in the specific embodiment, twelve petals 703 are arranged at the upper portion and the lower portion. After the arrangement, on the one hand, the petals 703 are more, the resistance is small, and the flow of the gas is not greatly affected, and on the other hand, the specific surface area of the hollow polyhedral ball 7 is large, and the role of splitting the foam can be fully played.

[0032] As shown in Figure 1 In order to facilitate understanding of the ability of the device to eliminate the foam, in the specific embodiment, the skimming area 2 is provided with an observation port 8, and the air inlet area 3 is provided with a cleaning operation port 5 for taking out the dirt and impurities adhered to the air inlet area 3.

[0033] Since the odorous gas contains corrosive components and a large amount of water vapor, in order to prevent the device from being corroded, in this specific embodiment, the grille is made of fiberglass and the hollow multifaceted sphere 7 is made of polypropylene plastic.

[0034] like Figure 1 As shown, in order to avoid the defoaming zone 2 affecting the air intake, in this specific embodiment, three air inlets 6 are evenly arranged along the circumference of the tank; by setting multiple air inlets 6, gas can enter the air intake zone 3 from multiple directions, ensuring the air intake.

[0035] like Figure 1 As shown, because the hollow multifaceted sphere 7 has a cutting effect on foam, impurities and dirt adhering to the foam often adhere to the hollow multifaceted sphere 7, thus affecting its cutting effect on the foam. In this specific embodiment, a spray zone 1 is provided inside the tank and above the defoaming zone 2. A spray assembly 9 is provided in the spray zone 1. The spray assembly 9 includes a connected water supply pipe and a nozzle. The water supply pipe is connected to a water source. A drain port 4 is provided at the lower part of the air inlet zone 3.

[0037] 1. By setting up a defoaming zone 2, the hollow multifaceted spheres 7 scattered within it play a role in obstructing and turbulent flow, increasing the gas turbulence, causing the foam carried in the sucked odor gas to break down, thereby intercepting the foam and preventing the odor gas from carrying the foam into the blower. This also prevents the foam from being contaminated with mixed sludge and other impurities and entering the blower, thus greatly reducing the frequency of downtime maintenance.

[0038] 2. By arranging a large number of petals in an alternating pattern, the hollow multifaceted sphere 7 is enhanced to increase its effect on breaking up foam, thereby improving the foam elimination capability of this device;

[0039] 3. By using glass steel and polypropylene plastic material, the corrosion resistance of the device can be improved, and the service life can be prolonged;

[0040] 4. By setting the spraying assembly 9, the hollow multi-surface ball 7 can be cleaned, the circulation use is realized, and the service life of the hollow multi-surface ball 7 is prolonged;

[0041] 5. The valve is controlled by the controller, the plurality of spray heads can complete the water spraying action according to the set program, the water pressure of the water channel is stable, and the plurality of spray heads are beneficial to improve the cleaning effect;

[0042] 6. By using the spiral spray head, the water pressure is ensured and the clogging is not easy, and the spraying work reliability is improved.
