Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clear and clear, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
A sewage odor treatment system of a garbage transfer station comprises an operation chamber. The operation chamber is a place where operations such as garbage collection and compression are performed. The empty compression box 9 is placed in the operation cavity, and the recovered garbage is poured into the compression box 9 and compressed by the compression box 9; when the compression box 9 is filled with the compressed garbage, the compression box 9 is mounted on a garbage truck, and the compression box 9 together with the compressed garbage is transported to a next processing point, such as a garbage power plant, through the garbage truck. It should be noted that the innovation point of the present technical solution is not the specific structure and working principle of the compression box 9, and in the prior art, the compression box 9 that can compress garbage can be applied to the present technical solution.
As shown in fig. 1, the operation chamber is formed by surrounding a floor 1, an inclined ceiling 2, a first side wall and a second side wall, a chamber entrance is formed in front of the operation chamber, a rear wall is arranged behind the operation chamber, and the inclined ceiling 2 is gradually inclined downwards from the front of the operation chamber to the rear of the operation chamber. In fig. 1, the front of the operating chamber is located on the right, and the rear of the operating chamber is located on the left.
In the present invention, the floor 1 may be understood as a floor of a building, the inclined ceiling 2 may be understood as a ceiling of a building, and the first and second sidewalls may be understood as walls of a building. Just like a general building, the ground 1, the inclined ceiling 2, the first side wall and the second side wall are connected with each other, so that a pipeline building with two openings on two sides can be formed, and the middle space is the operation chamber. The back wall is arranged at the back of the operation chamber, the door plate 3 which can be opened and closed is arranged at the chamber entrance in front of the operation chamber, and a relatively closed space can be formed after the operation chamber is matched with the back wall and the door plate 3.
In the prior art, in order to prevent odor from diffusing, an operation chamber is generally isolated from the outside air, and the operation chamber is completely sealed, so that the odor can be circulated only in the range of the operation chamber. However, it is inevitable that more or less odor diffuses out. In order to solve the problem of preventing odor from diffusing, the technical scheme is characterized in that, on one hand, the operation chamber is not completely sealed, and a vent 31 is arranged on the door plate 3; on the other hand, an exhaust port 4 is provided at the bottom of the rear wall, and an exhaust gas treatment device 41 is provided outside the exhaust port 4. This is a great difference of the present invention from the prior art. Generally, in order not to spread the malodor, the prior art generally seals the entire operating chamber without leaving vents 31.
In specific work, the door plate 3 is opened, the compression box 9 is pushed into the operation chamber, then garbage is put into the compression box 9, and the compression box 9 is controlled to work. During the operation of the compression box 9, an odor is inevitably generated, at this time, the exhaust equipment in the exhaust gas treatment device 41 continuously extracts air from the operation chamber through the exhaust port 4, the ventilation opening 31 at the inlet and outlet of the chamber is matched with the exhaust gas treatment device 41, a negative pressure is formed in the operation chamber, external fresh air continuously flows in from the ventilation opening 31, enters the exhaust gas treatment device 41 together with the odor to be purified, and is then discharged into the external air again through the exhaust passage 42. At this time, the odor has already been purified by the exhaust gas treatment device 41, and no pollution is caused to the air.
The key points of the technical scheme are that two door plates 3 are arranged at the inlet and outlet of the cavity, and the operation cavity is not airtight, but is provided with a ventilation opening 31; secondly, an inclined ceiling 2 is provided.
Unlike the prior art, which limits the odor diffusion by sealing, the present invention achieves this by creating a negative pressure space. However, in order to create a negative pressure space, it is not sufficient to provide the ventilation opening 31 in the door panel 3, and it is also necessary to provide an inclined ceiling 2. The inclined ceiling 2 makes the space of the operation chamber gradually smaller from front to back, which can greatly improve the air extraction efficiency of the exhaust gas treatment device 41, and if the upper side of the operation chamber is a generally horizontally arranged ceiling, the space of the operation chamber will greatly be improved, and the exhaust gas treatment device 41 is difficult to extract air from the operation chamber. Therefore, without the cooperation of the vent 31 and the inclined ceiling 2, negative pressure cannot be efficiently formed in the operation chamber, and the suction effect is greatly impaired.
In addition, the inclined ceiling 2 can reduce the volume of the operation space and also reduce the manufacturing cost. If the ceiling is made higher, more material is needed, and more material tends to mean higher costs. Therefore, in the present technical solution, the inclined ceiling 2 has two beneficial effects, namely, ensuring reduced space and improved air extraction efficiency, and reducing manufacturing cost.
In the process of compressing the garbage by the compression box 9, water in the garbage is extruded to form percolate, and the percolate is sewage and one of sources of odor. In this technical solution, in order to prevent the diffusion of sewage, as shown in fig. 2, a V-shaped groove 11 is provided on the ground 1.
The V-shaped groove 11 is a groove body with two high sides and a low middle, and sewage discharged from the compression box 9 can be gathered to the center of the V-shaped groove 11. In addition, as shown in fig. 1, the V-shaped groove 11 is disposed along the front-rear direction of the operation chamber, and the V-shaped groove 11 is gradually inclined downward from the front direction of the operation chamber to the rear of the operation chamber, and a liquid collecting port 12 is disposed at the lowest position of the V-shaped groove 11, and the liquid collecting port 12 is communicated with an underground sewage drain 17. Thus, the sewage further flows from the front to the rear of the V-groove 11, finally flows into the liquid collecting port 12, and is discharged through the underground sewage pipe 17.
As shown in fig. 3, preferably, the bottoms of the first side wall and the second side wall are provided with a plurality of flushing nozzles 5, and the water outlet direction of the flushing nozzles 5 is toward the V-shaped groove 11. During the treatment of waste, there may be scattered waste or sewage on the floor 1 of the operating chamber. The water column is sprayed out by the flushing nozzle 5, so that the ground 1 can be flushed, and the operation cavity is kept clean and tidy.
In addition, in order to prevent the solid garbage from entering the underground sewage pipe 17 from the liquid collecting port 12 to cause blockage, a filter screen is preferably further arranged on the liquid collecting port 12. Further, a sedimentation tank 18 is preferably also provided below the liquid collection port 12, also helping to prevent clogging of the underground sewer 17.
As shown in fig. 4, the door panel 3 preferably includes a first side plate 32 and a second side plate 33, the first side plate 32 being hinged to the first side wall, and the second side plate 33 being hinged to the second side wall. A first notch is formed in the first side plate 32, and a second notch is formed in the second side plate 33; when the first side plate 32 and the second side plate 33 are closed, the ventilation opening 31 is formed between the first notch and the second notch.
Specifically, when the door panel 3 needs to be opened, an operator pushes or pulls the first side plate 32 and the second side plate 33, the first side plate 32 rotates with the connection structure on the first side wall as an axis, and the second side plate 33 rotates with the connection structure on the second side wall as an axis, so that the opening or closing function of the door panel 3 is realized. Normally, the first side plate 32 and the second side plate 33 are both in a closed state, and the first side plate 32 and the second side plate 33 are opened only when the compression box 9 enters and exits the operation chamber, so that the compression box 9 can pass through; when the first side plate 32 and the second side plate 33 are closed, the first notch on the first side plate 32 and the second notch on the second side plate 33 form the ventilation opening 31 as shown in fig. 4.
Specifically, the first side plate 32 has a first notch near the ground 1 and near the second side plate 33, and the second side plate 33 has a second notch near the ground 1 and near the first side plate 32.
Through the first curb plate 32 and the second curb plate 33 of articulated setting, can realize the function of opening and shutting of door plant 3 with simple structure, form vent 31 on door plant 3 simultaneously, be favorable to making the negative pressure in the operating chamber.
Preferably, the first side plate 32 and the second side plate 33 are provided with viewing windows, and transparent glass is arranged on the viewing windows, so that an operator can observe the internal condition of the operation chamber without opening the door panel 3.
The above technical solution only provides one implementation manner of the door panel, and it is not said that the door panel can be implemented only in such a manner. If the door plate is a side-pull type door plate, an operator controls the opening and closing by pulling the door plate; for another example, the door plate is a lifting door plate, and an operator controls the opening and closing by controlling the lifting of the door plate. However, the first side plate and the second side plate which are arranged in a hinged manner are adopted to realize the door plate function, and the side pull rail, the lifting device and the like are not additionally increased in the mode, so that the whole system is simpler in structure and has the advantages of space saving, convenience in operation, low cost and the like.
As shown in fig. 1, a sewage odor treatment system of a refuse transfer station preferably further comprises a horizontal ceiling 6. The inclined ceiling 2 is arranged at a position close to the rear of the operation chamber, the horizontal ceiling 6 is arranged at a position close to the front of the operation chamber, and one side of the horizontal ceiling 6 is connected with one side of the highest position of the inclined ceiling 2; a gradually decreasing inclined space is formed between the inclined ceiling 2 and the floor 1, and a rectangular space is formed between the horizontal ceiling 6 and the floor 1. If the horizontal ceiling 6 is not provided, the operation chamber is only an inclined space, and the space is small, which is not conducive to the operation of loading and unloading the compression box 9.
The function of the horizontal ceiling 6 is to provide sufficient space for loading and unloading the compression box 9. In the process of loading and unloading the compression box 9 on the garbage truck, the compression box 9 is lifted or put down by a lifting device, which requires a sufficient operation space. In the present invention, by providing the horizontal ceiling 6, the operation chamber is divided into two parts of spaces according to the shape, one part is a large rectangular space located in front of the operation chamber, and the other part is a gradually decreasing inclined space located in rear of the operation chamber. The operation of loading and unloading the compression box 9 is performed in a rectangular space. The provision of the horizontal ceiling 6 thus provides, on the one hand, sufficient space for loading and unloading the compression box 9 and, on the other hand, ensures the efficiency of the formation of the negative pressure in the operating chamber.
As shown in fig. 2, preferably, both sides of the V-shaped groove 11 are provided with a first rail 13 and a second rail 14, respectively; a first inclined high platform 15 is arranged between the first rail 13 and the first side wall, the first inclined high platform 15 gradually inclines downwards from the first side wall to the first rail 13, and a step-shaped transition is formed between the first inclined high platform 15 and the first rail 13; a second inclined plateau 16 is disposed between the second rail 14 and the second side wall, the second inclined plateau 16 gradually inclines downwards from the second side wall to the second rail 14, and a step-shaped transition is formed between the second inclined plateau 16 and the second rail 14.
Typically, the bottom of the compression box 9 is provided with wheels, and the compression box 9 is rolled into and out of the operating chamber by the wheels. The first rail 13 and the second rail 14 function as wheels supporting the compression box 9, whereby the first rail 13 and the second rail 14 are horizontal. However, in order to ensure that sewage can smoothly collect, a first inclined plateau 15 is provided between the first rail 13 and the first side wall, and the first inclined plateau 15 gradually inclines downward from the first side wall to the first rail 13; a second inclined plateau 16 is disposed between the second rail 14 and the second side wall, and the second inclined plateau 16 gradually inclines downward from the second side wall toward the second rail 14.
A step-like transition is formed between the first inclined plateau 15 and the first rail 13, and a step-like transition is formed between the second inclined plateau 16 and the second rail 14. The two step-shaped transitions can play a limiting role. When the travel track of the compression box 9 shifts during the movement of the compression box 9, the wheels of the compression box 9 can be abutted against the step-shaped transition, and the wheels are subjected to a reaction force and cannot continue to shift. Therefore, the technical scheme can play a limiting role on the compression box 9, and meanwhile, the sewage collection efficiency is not affected.
Preferably, a reinforced concrete layer is disposed under the ground 1, and polyurethane mortar layers are further disposed on the upper surfaces of the V-shaped groove 11, the first inclined plateau 15 and the second inclined plateau 16. Specifically, the thickness of the polyurethane mortar layer on the upper surface of the V-shaped groove 11 is 8-12mm, and the thickness of the polyurethane mortar layer on the upper surfaces of the first inclined plateau 15 and the second inclined plateau 16 is 4-6mm. More specifically, the thickness of the polyurethane mortar layer on the upper surface of the V-groove 11 is 10mm, and the thicknesses of the polyurethane mortar layers on the upper surfaces of the first inclined plateau 15 and the second inclined plateau 16 are 5mm. In addition, the model of the reinforced concrete used in the reinforced concrete layer is more than C35, such as C35, C40, C45 and the like, so that the strength of the ground 1 is ensured, and cracking is prevented.
The polyurethane mortar layer has the function of corrosion resistance. Generally, the percolate is corrosive, so that the ground 1 can be prevented from being corroded by the polyurethane mortar layer to form cracks or nicks. Specifically, the percolate is more in contact with the V-groove 11 and less in contact with the first and second inclined elevations 15 and 16, so that the thickness of the polyurethane mortar layer on the upper surface of the V-groove 11 is large, while the thickness of the polyurethane mortar layer on the upper surfaces of the first and second inclined elevations 15 and 16 is small, and the cost can be controlled while the corrosion prevention function is achieved.
Fig. 2 clearly discloses the structural relationship of the floor 1 with the V-groove 11, the first rail 13, the second rail 14, the first inclined plateau 15 and the second inclined plateau 16.

First, the first horizontal steel plate 71 is laid on the first rail 13, the second horizontal steel plate 81 is laid on the second rail 14, the first horizontal steel plate 71 and the second horizontal steel plate 81 are used for supporting the compression box 9, and the pressure of the compression box 9 on the ground 1 is reduced through the first horizontal steel plate 71 and the second horizontal steel plate 81, so that the ground is ensured. Next, the first inclined steel plate 72, the second inclined steel plate 73, the third inclined steel plate 82, and the fourth inclined steel plate 83 function to form smooth transitions between the first inclined ramp 15 and the first rail 13, between the first rail 13 and the V-groove 11, between the second inclined ramp 16 and the second rail 14, and between the second rail 14 and the V-groove 11, and to seal the gap of the floor 1 after pouring cement or concrete or the like into the gap of the edge; if not, a deep gap is formed along the first, second, third and fourth vertical steel plates 74, 75, 84 and 85, and it is difficult to clean once the infiltration enters the gap.

As shown in fig. 4, preferably, a lifting window 34 is further disposed above the door panel 3. In order to provide sufficient operating space for loading and unloading the compression box 9, the height of the chamber access opening must be large enough. When the height of the door panel 3 is the height of the entrance and the exit of the chamber, the quality of the door panel 3 is greatly increased, so that the door panel is difficult to push, and inconvenience is brought to the operation of the door panel. Therefore, the lifting window 34 can be arranged on the smaller door plate and then arranged on the door plate 3, so that the quality of the door plate 3 can be reduced, and the door plate 3 can be conveniently operated.
When the compression box 9 needs to be assembled and disassembled, the first side plate 32 and the second side plate 33 can be opened first, and then the lifting window 34 is controlled to ascend, so that the inlet and outlet of the chamber are completely opened; after the loading and unloading are completed, the first side plate 32 and the second side plate 33 can be closed first, and then the lifting window 34 is controlled to descend, so that the entrance and exit of the chamber are closed, and only the ventilation opening 31 is reserved.
Specifically, in the present embodiment, the heights of the first side plate 32 and the second side plate 33 are 2700mm, the height of the lifting window 34 is 1300mm, the height of the ventilation opening 31 is 1800mm, and the width of the ventilation opening 31 is 900mm. With such a size design, a negative pressure space is formed in the operation chamber. At this time, the flow rate of air flowing into the operation chamber from the vent 31 can reach 2m/s, and the odor collection rate can reach more than 90%; if the door panel 3 and the ventilation opening 31 are not provided, the flow rate of air flowing into the operation chamber is 0-0.3m/s, and the odor diffusion cannot be prevented.
The height of the ventilation opening 31 is 1800mm, and the width of the ventilation opening 31 is 900mm, so that the hand-push garbage collection vehicle can conveniently go in and out. In this technical scheme, the vent 31 has two functions, firstly, cooperates with the exhaust gas treatment device 41 to form negative pressure in the operation chamber, and secondly, is convenient for the operator to push in or pull out the hand-push type garbage collection vehicle through the vent without opening the door panel 3.
Preferably, the operating chamber is provided with at least one, in particular two, three or four. Garbage is treated in a parallel mode, so that the garbage treatment capacity is improved.
As shown in fig. 1, a front shielding plate 35 is preferably provided in front of the operation chamber, and sunlight and rainwater are shielded by the front shielding plate 35, thereby providing a relatively comfortable working environment for an operator. A rear shielding plate 43 is provided above the exhaust passage 42, and foreign matter is prevented from falling into the exhaust passage 42 to cause clogging by the rear shielding plate 43.
In summary, the present invention provides a sewage odor treatment system for a garbage transfer station, which, on one hand, collects sewage through a V-shaped groove 11 disposed obliquely, thereby preventing sewage from diffusing; on the other hand, by tilting the ceiling 2, the exhaust gas treatment device 41 and the vent 31, a negative pressure is produced in the operation chamber, so that fresh air is flushed from the vent 31, preventing the diffusion of odor. Therefore, the sewage odor treatment system of the garbage transfer station has the advantage of low cost, can well prevent the diffusion of sewage and odor, and furthest reduces the influence on surrounding residents
It is to be understood that the invention is not limited in its application to the examples described above, but is capable of modification and variation in light of the above teachings by those skilled in the art, and that all such modifications and variations are intended to be included within the scope of the appended claims.
