[0022] The present invention will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0023] Example 1

[0024] The utility model of the storage tank top odor adsorption device, such as Figure 1As shown, it includes a tank body 1, a breathing hole 2, an adsorption tank air intake pipe 3, filter materials, and several filter boxes. The breathing hole 2 is opened at the bottom of the tank body 1, the adsorption tank air intake pipe 3 is arranged at the top of the tank body 1, and several filter boxes are stacked in the tank body 1, and the filter material is arranged in the filter boxes.

[0025] Example 2

[0026] On the basis of Example 1, Figures 1 to 3 As shown, the filter box includes two stacked first filter boxes 4 and several second filter boxes 5. The two first filter boxes 4 are respectively arranged above and below the several second filter boxes 5. The first filter box 4 is provided with several filter holes 6, and the second filter box 5 is provided with guide holes 7. The guide holes 7 of the two adjacent second filter boxes 5 are staggered.

[0027] The first filter box 4 and the second filter box 5 are both cylindrical troughs with flat bottoms and raised edges.

[0028] In some specific embodiments, three second filter boxes 5 are provided, and the guide holes 7 of two adjacent second filter boxes 5 are staggered by 180°. The exhaust gas has an S-shaped direction in the tank body, which increases the contact area between the odorous gas and the activated carbon filter cotton for sufficient adsorption.

[0029] In some embodiments, a breathing hole 2 is provided at the bottom of the tank body 1 , and a plurality of breathing holes 2 are provided. The breathing holes 2 are used to discharge the adsorbed and purified gas out of the tank body 1 .

[0030] The filter materials are activated carbon and filter cotton.

[0031] The bottom of the tank body 1 is also provided with an inspection and disassembly port 8. When the activated carbon and filter cotton need to be replaced, the inspection and disassembly port 8 is opened and the filter cartridge in the tank body 1 is taken out for replacement. During operation, the activated carbon and filter cotton are replaced regularly according to the adsorption condition of the activated carbon in the adsorption tank and the volatility of the material in the storage tank.

[0032] The odor adsorption device for the top of a storage tank of the present invention also includes an adsorption tank condensate outlet 9 and an adsorption tank air inlet tee 10. The adsorption tank air inlet tee 10 connects the adsorption tank air inlet pipe 3, the adsorption tank condensate outlet 9, and the volatile gas outlet on the top of the storage tank, respectively. The adsorption tank condensate outlet 9 is also equipped with a non-return flap valve. If condensate is present, it can be discharged through the flap valve of the adsorption tank condensate outlet 9 by its own weight, while the gas enters the tank body 1 for adsorption.

[0033] In this embodiment, the storage tank top odor adsorption device of the present invention is arranged on the storage tank top, and the storage tank odor is introduced into the tank body of the present invention through the adsorption tank air inlet pipe.

[0034] The working process of the odor adsorption device on the top of the storage tank of the present invention is as follows: first, the adsorption tank air inlet tee 10 is respectively connected to the adsorption tank air inlet pipe 3, the adsorption tank condensate outlet 9 and the volatile gas exhaust port on the top of the storage tank, and then the volatile gas enters the tank body 1 through the adsorption tank air inlet pipe 3, and enters the second filter box 5 through the first filter box 4 at the upper end. There are 3 second filter boxes 5, which are stacked as an upper layer, a middle layer and a lower layer respectively. The volatile gas enters the second filter box 5 in the middle layer from the left hole of the second filter box 5 in the upper layer, and then enters the second filter box 5 in the lower layer from the right hole of the second filter box 5 in the middle layer, and then enters the first filter box 4 at the lower end. The exhaust gas has an S-shaped direction in the tank body 1, which increases the contact area between the gas and the activated carbon filter cotton and is fully adsorbed. Finally, the gas is discharged through the breathing hole 2 at the bottom of the tank body 1.

[0035] Example 3

[0036] The difference from Example 2 is that, in this embodiment, the tank body 1 is arranged on the bottom surface, and a support leg is also provided at the bottom of the tank body 1 for supporting the tank body 1, while ensuring that there is a gap between the tank body 1 and the ground, which does not affect the gas discharge from the breathing hole 2.

[0037] The utility model relates to a tank top odor adsorption device, which is placed on the tank top. It has a small size, a simple structure, and is easy to disassemble. It can fully absorb odors emitted from the tank, is environmentally friendly and efficient, and can effectively reduce the concentration of VOCs (volatile organic compounds). The activated carbon and filter cotton can be replaced regularly according to the activated carbon adsorption situation.
