Description

Technical Field

[0001] The utility model relates to the technical field of biological deodorization, in particular to a biological deodorization box. Background Art

[0002] The biological deodorization tank is a method that mainly utilizes the biological oxidation and decomposition of microorganisms to convert pollutants into harmless or low-harm substances. When the odor enters the biological deodorization tank, it first passes through the pre-wash tank for humidification and dust removal, and then enters the biological filter tank. The odor passes through the moist, porous, and active microbial filter layer, and utilizes the adsorption, absorption, and degradation functions of microbial cells on odorous substances to achieve odor treatment.

[0003] The current biological deodorization box is generally divided into two areas with bottoms connected by a partition, one is a pre-washing tank, and the other is a biological filter. The odor enters from the top of the pre-washing tank, and then enters the biological filter from the bottom. The treated gas is discharged from the top of the biological filter. For example, Chinese patent CN217163865U discloses a biological deodorization box, that is, this structure. This structure has a poor odor treatment effect because both the pre-washing tank and the biological filter adopt a single-chamber structure, so the odor circulation path is short.

DETAILED DESCRIPTION

[0024] The utility model is further described below in conjunction with the accompanying drawings.

[0025] The positions mentioned in this specification are based on the positions of the biological deodorizing box of the utility model during normal operation, and do not limit the positions during storage and transportation. They only represent relative position relationships, not absolute position relationships.

[0026] Embodiment 1:

[0027] like Figure 1 and Figure 2 As shown together, a biological deodorizing box includes a box body 1 and a plurality of partitions 2 arranged parallel and vertically in the box body 1. In this embodiment, four partitions 2 are provided. In actual application, three or five partitions can be designed as needed, and this embodiment does not limit this. The partitions 2 divide the space in the box body 1 into a plurality of small chambers arranged side by side. Because four partitions 2 are provided in this embodiment, the small chambers are divided into five.

[0028] An air inlet 11 is provided on the leftmost small chamber, and an air outlet 12 is provided on the rightmost small chamber; an air outlet 21 is provided on the partition 2, and the air outlets 21 on adjacent partitions 2 are located on different upper and lower sides, so that when the odor flows between adjacent small chambers, it is in the form of air intake at the upper end and air outlet at the lower end, or air intake at the lower end and air outlet at the upper end, so that the flow path of the odor is a rotary path.

[0029] The small chambers are divided into a pre-wash chamber and a deodorization chamber according to their functions from the air inlet 11 to the air outlet 12. The pre-wash chamber and the deodorization chamber each include a plurality of small chambers. In order to improve the treatment effect in this embodiment, the pre-wash chamber and the deodorization chamber each include at least two small chambers. Biological fillers are arranged in the deodorization chamber, and ordinary fillers are arranged in the pre-wash chamber. The ordinary fillers may be PVC fillers or composite fillers.

[0030] A filler support 6 is installed in the pre-wash chamber and the deodorization chamber. The filler support 6 includes a support leg 61 fixed to the bottom of the box body 1 and a filler support frame 62 fixed to the top of the support leg 61. The filler support frame 62 is filled with corresponding fillers, that is, the pre-wash chamber is filled with ordinary fillers, and the deodorization chamber is filled with biological fillers. The top and bottom of the filler support frame 62 are both provided with air distribution plates, and a number of through holes are evenly arranged on the air distribution plates. The air distribution plates have the effect of evenly distributing air and water, thereby increasing the contact frequency and contact area between the odor and the spray liquid, and ensuring the odor treatment effect.

[0031] The top of the pre-wash chamber and the deodorization chamber are both provided with a spray device 3, and the bottom is provided with a water collection tank 4, and the water collection tank 4 is connected to the spray device 3 through a water pump 5. In order to prevent the spray liquid in the water collection tank 4 from hindering the flow of odor, the air port 21 at the bottom of the partition 2 is higher than the water collection tank 4; at the same time, in order to increase the contact time between the spray liquid and the odor, the air port 21 at the top of the partition 2 is lower than the spray device 3, thereby ensuring that the odor is covered by the spray liquid during the entire circulation process.

[0032] Furthermore, in order to improve the pre-washing effect, an air inlet pipe 111 is fixed in the air inlet 11, and the air inlet pipe 111 extends inward and is inserted into the water collecting tank 4, and is immersed in the bottom of the spray liquid. The spray liquid can wash the odor.

[0033] The water pipes of the spray devices 3 of the pre-wash chamber and the deodorization chamber are independent of each other, thereby meeting the needs of production and replenishment of biological nutrient solution.

[0034] In actual application, when the odor is washed in the pre-washing chamber, impurities such as filler residues are mixed in the spray water and enter the water collection tank 4 with the spray water. If these impurities enter the spray device 3, it is easy to block the spray device 3. Therefore, a water outlet 13 is provided on the side of the box body 1 corresponding to the water collection tank 4, and a cover net 7 is provided on the water outlet 13.

[0035] Embodiment 2:

[0036] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, although the cover net 7 can filter impurities, the impurities still accumulate at the cover net 7 and need to be cleaned regularly, otherwise the impurities cannot be discharged. In order to conveniently discharge the impurities from the box body 1, this embodiment is further improved on the basis of the first embodiment.

[0037] A drainage ditch 41 is provided at the bottom of the water collecting tank 4, and a cover net 7 is provided on the drainage ditch 41. The water outlet 13 is located in the drainage ditch 41 and at the bottom of the cover net 7; the drainage ditch 41 is convenient for collecting and discharging circulating water.

[0038] The cover net 7 includes a filter body 71 that bends into the drain ditch 41. The filter body 71 is an arc-shaped structure and is evenly distributed with filter holes. Both sides of the filter body 71 are provided with flanges 711 fixed to the drain ditch 41. The two side walls of the drain ditch 41 are provided with limiting grooves for fixing the flanges 711. The flanges 711 are fixed in the limiting grooves, so that the flanges 711 are fixed to the drain ditch 41. After the flanges 711 are installed on the drain ditch 41, the top of the flanges 711 does not protrude from the top of the drain ditch 41, thereby avoiding blocking of impurities and preventing the impurities from entering the filter body 71.

[0039] A slag discharge pipe 72 having the same curvature as the filter body 71 is fixed at one end thereof. A slag discharge port 14 is provided on the housing 1 above the water outlet 13, and the slag discharge pipe 72 extends out of the housing 1 from the slag discharge port 14 in a sealed manner, that is, the outer circumferential direction of the slag discharge pipe 72 forms a relative seal with the slag discharge port 14, thereby preventing the circulating fluid from leaking from this point. A slag discharge port 73 is provided at the bottom of one end of the slag discharge pipe 72 extending out of the housing 1, and a slag discharge box 731 is screwed on the slag discharge port 73.

[0040] Because the slag discharge port 14 is located above the water outlet 13, during the circulating spray water extraction process, impurities are driven by the water flow along the filter body 71 into the slag discharge pipe 72, and then fall into the slag discharge box 731. The slag discharge box 731 is unscrewed regularly to achieve regular cleaning of the slag discharge box 731.

[0041] In order to facilitate the impurities to enter the slag discharge pipe 72 along the filter body 71 under the action of gravity and water flow, and then be discharged from the interior of the box body 1, the filter body 71 is in an inclined state, and the end thereof connected to the slag discharge pipe 72 is the lowest.

[0042] When cleaning, in order to prevent the circulating water from flowing out of the slag outlet 73 after the slag box 731 is unscrewed, a piston is slidably installed in the slag pipe 72. The piston is in sealing contact with the slag pipe 72 and can slide in the slag pipe 72. A piston rod is installed on the piston, and an external thread is provided on the piston rod. The slag pipe 72 is provided with a threaded sleeve that matches the external thread. A hand wheel is installed at one end of the piston rod that passes through the slag pipe 72. By selecting the hand wheel, the piston is controlled to move in the slag pipe 72. When the slag box 731 needs to be unscrewed, the piston is moved to the area between the slag outlet 73 and the slag outlet 14, thereby closing the slag pipe 72. When the replacement is completed, the piston is returned to the outside of the slag outlet 73, thereby reopening the slag pipe 72.

[0043] Embodiment three:

[0044] like Figure 4 and Figure 5 As shown in the figure, although some larger impurities in the second embodiment will flow into the slag box 731 with the water flow, some sticky dust or impurities are stained on the filter body 71 and will not flow. In the long run, it is easy to block the filter body 71, so it is necessary to clean the cover net 7 regularly. The cleaning and disassembly of the cover net 7 is relatively complicated. This embodiment is further improved on the basis of the second embodiment, so that the cover net 7 can be removed for cleaning.

[0045] The slag discharge port 14 is a circular structure, and its diameter is consistent with the diameter of the slag discharge pipe 72. Since the slag discharge pipe 72 has the same curvature as the filter body 71, the slag discharge port 14 allows the slag discharge pipe 72 and the filter body 71 to be inserted and removed. However, since the filter body 71 is provided with a convex edge 711, in order to prevent the slag discharge port 14 from interfering with the convex edge 711, notches 141 are provided on both sides of the slag discharge port 14 to avoid the convex edge 711, thereby ensuring that the cover net 7 can be inserted and removed from the slag discharge port 14 as a whole.

[0046] After the cover net 7 is inserted into the slag discharge port 14, in order to fix and maintain the sealing, the slag discharge pipe 72 is sealed and detachably fixed on the slag discharge port 14 through the sealing cover 75, and the fixing method is as follows: a mounting column 142 is arranged on the outer side of the slag discharge port 14, the mounting column 142 is concentric with the slag discharge port 14, the slag discharge port 14 is located in the inner hole covering area of ​​the mounting column 142, and a sealing gasket 76 is clamped between the inner hole of the mounting column 142 and the slag discharge pipe 72; a threaded hole is arranged on the mounting column 142, and a through hole is opened on the circumference of the sealing cover 75 corresponding to the threaded hole, the sealing cover 75 is fixedly installed on the mounting column 142 by bolts, and the sealing gasket 76 is pressed tightly to achieve sealing.

[0047] When the cover net 7 adopts a spot check structure, in order to facilitate the fixation of the cover net 7, the limiting groove on the drainage ditch 41 adopts a slide groove structure, that is, corresponding to the position of the notch 141 of the slag discharge port 14, slide grooves are arranged on both sides of the drainage ditch 41. When the cover net 7 is inserted from the slag discharge port 14, it can be directly inserted into the slide groove, and the slide groove clamps the convex edge 711 of the cover net 7, thereby achieving fixation.

[0048] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
