People often use biological desulfurization towers to ferment kitchen waste and flue gas.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] AsFigures 1-4 As shown in the figure, a biological desulfurization tower for anaerobic fermentation of kitchen waste includes a base 1 and a desulfurization tower 2 fixedly connected to the upper surface of the base 1. A smoke pipe 3 is fixedly connected to the front side of the outer circumference of the lower end of the desulfurization tower 2. An intake flange pipe 4 is fixedly connected to the right end of the smoke pipe 3. A top pipe 5 is fixedly connected to the upper surface of the desulfurization tower 2. An outlet pipe 6 is fixedly connected to the lower surface of the right end of the top pipe 5. The inner bottom of the smoke pipe 3 extends to the outside and is provided with a primary filtration mechanism 7. The primary filtration mechanism 7 includes a collection drawer 71 slidably connected to the inner bottom of the smoke pipe 3 and extending to the outer surface. Above the collection drawer 71 is a sliding frame 72, and a plurality of inclined plates 73 are fixedly connected to the inner surface of the sliding frame 72.

[0022] By adopting the above technical solution, when the desulfurization tower 2 intakes air, it needs to intake air through the intake flange pipe 4 connected to the pipeline. After the flue gas enters the smoke pipe 3, a plurality of inclined plates 73 on the inner surface of the sliding frame 72 can simply block the flue gas, initially intercept the oil stains in the flue gas. The intercepted oil stains fall into the collection drawer 71 along the inclined plates 73 for collection. The operator can regularly pull out the collection drawer 71, dump the collection drawer 71, and at the same time clean the sliding frame 72 and the inclined plates 73. This design can achieve the function of primary filtration and reduce the filtration pressure of the desulfurization tower 2.

[0023] As Figures 1-2 shown, a pulling groove 711 is opened on the outer surface of the collection drawer 71, and the outer surface of the collection drawer 71 is designed to fit the outer surface of the smoke pipe 3. The pulling groove 711 can facilitate the sliding out of the collection drawer 71, and the fitting design can prevent the flue gas from overflowing.

[0024] Furthermore, an arc-shaped pipe 8 is fixedly connected to the upper surface of the top pipe 5. One end of the arc-shaped pipe 8 is provided with a blower 9, and the blower 9 is fixedly connected to the upper surface of the top pipe 5.

[0025] Furthermore, a pedal 10 is fixedly connected to the upper side of the outer circumferences of the desulfurization tower 2 and the outlet pipe 6, and the pedal 10 is fixedly welded to the upper side of the outer circumferences of the desulfurization tower 2 and the outlet pipe 6.

[0026] Furthermore, a protection plate 11 is fixedly connected to the upper surface of the pedal 10, and the left side of the protection plate 11 is of an open design.

[0027] Furthermore, a ladder 12 is fixedly connected to the left outer surface of the pedal 10, and the ladder 12 is arranged on the left side of the desulfurization tower 2.

[0028] Working principle: When using this biological desulfurization tower for anaerobic fermentation of kitchen waste, first, when the desulfurization tower 2 of this device intakes air, it needs to intake air through the intake flange pipe 4 connecting the pipeline. After the flue gas enters the smoke pipeline 3, several inclined plates 73 on the inner surface of the sliding frame 72 can simply block the flue gas, preliminarily intercept the oil stains in the flue gas, and the intercepted oil stains fall onto the collection drawer 71 along the inclined plates 73 for collection. The operator can regularly pull out the collection drawer 71, dump the collection drawer 71, and at the same time clean the sliding frame 72 and the inclined plates 73. When it is necessary to adjust the outlet pipe speed of the gas inside the desulfurization tower 2, the blower 9 can be appropriately adjusted to rotate and blow air, driving the gas inside the desulfurization tower 2 to circulate at an accelerated speed, so as to achieve the purpose of adjustment. The operator can climb to the pedal 10 through the ladder 12 to maintain the blower 9 or the top of the desulfurization tower 2, or put garbage into the desulfurization tower 2 for fermentation. This is the working principle of this biological desulfurization tower for anaerobic fermentation of kitchen waste.
