Description

Technical Field

[0001] The invention relates to the technical field of domestic waste transfer and transportation, and in particular to a method for suppressing odor in a waste transfer workshop and a waste transfer workshop. Background Art

[0002] The Chinese invention patent with application number 202410519116X discloses a method and device for cleaning a garbage truck in a domestic waste transfer station. The patent can not only perform high-pressure gas cleaning on the vehicle body by setting up a driving lane, a high-pressure jet device and a negative pressure suction device, but also extract and deodorize the odor in the transfer workshop through the negative pressure suction device.

[0003] The garbage stored in the front-end garbage collection truck contains a large amount of sewage, which is easy to leak from the garbage truck cargo box during transportation. At the same time, when working on rainy days, sewage contaminated by the vehicle body will drip onto the garbage truck body. Since a large number of front-end garbage collection trucks will enter and exit the driving lanes during working hours, a lot of garbage and sewage will accumulate in the driving lanes, causing the driving lanes to stink. In addition, when the front-end garbage collection truck performs gas flushing in the driving lanes, the dirt that falls from the flushing will also pollute the driving lanes, causing the driving lanes to stink.

[0004] Moreover, in the hot summer weather, the garbage collection trucks and the garbage themselves will emit a lot of odor. If the odor emitted by the garbage collection trucks and the garbage is not suppressed, the driving lanes will also stink.

[0005] In addition, when the garbage collection truck dumps garbage into the garbage loading funnel set at the bottom of the garbage dumping isolation room, the falling garbage will generate strong backwash odorous airflow, which has a large speed and may escape from the driving lane; and odor sources such as dirt and odor-producing bacteria will be attached to the surface of the garbage loading funnel, and these dirt and odor-producing bacteria will also continue to emit odor, so it is also necessary to suppress the backwash odorous airflow and the odor sources attached to the surface of the garbage loading funnel. Summary of the invention

[0006] In view of this, the purpose of the present invention is to provide a method for suppressing odor in a garbage transfer workshop and a garbage transfer workshop, so as to solve the technical problems such as the front-end garbage collection truck polluting the transfer workshop.

[0014] Furthermore, the garbage loading hopper arranged at the bottom of the garbage dumping isolation room is provided with cavities for accommodating refrigeration medium around it.

[0015] Furthermore, the garbage collection trough has an extension section which exceeds the top of the freezing cavity and horizontally extends toward the middle of the garbage isolation room.

[0016] Furthermore, the freezing cavity is also provided with a cold air inlet and exhaust microholes for slowly releasing cold air.

[0018] Furthermore, the garbage collection trough and the top of the freezing chamber are an integrated structure, the front end of the garbage collection trough is a slope structure for facilitating the garbage truck to enter and exit smoothly, and the rear end of the garbage collection trough has a step structure for blocking the garbage truck and withstanding the impact of the garbage truck.

[0019] Furthermore, the garbage transfer workshop also includes an upper door arranged at the top of the driving lane, a left door arranged on the left side of the driving lane, and a right door arranged on the right side of the driving lane.

[0020] Furthermore, a refrigeration airbag is provided on the top of the driving lane.

[0021] Furthermore, a refrigeration air bag is provided on the top of the garbage dumping isolation room.

[0022] Furthermore, the refrigeration airbag is provided with a cold air inlet and a plurality of micro holes for slowly releasing the cold air.

[0023] Furthermore, the refrigeration airbag is made of a low-temperature resistant and flexible film.

[0024] Furthermore, a pull rope is provided on the refrigeration airbag, and connectors connected to the pull rope are respectively provided on the top of the garbage dumping isolation room and the driving lane.

[0025] Furthermore, the garbage transfer workshop also includes a negative pressure suction device for extracting gas from the garbage dumping isolation room.

[0026] Furthermore, the garbage transfer workshop also includes a negative pressure suction air intake structure arranged on the upper door edge, the left door edge and the right door edge and connected to the negative pressure suction device.

[0027] Furthermore, a plurality of open containers are arranged in the driving lane, and the containers are filled with plant deodorizing liquid.

[0028] Beneficial effects of the present invention:

[0029] 1. The odor suppression method and the garbage transfer workshop of the present invention refrigerate the bottom of the driving lane, specifically, a freezing chamber for carrying a garbage collection truck is arranged at the bottom of the driving lane, and a garbage collection trough is arranged on the top of the freezing chamber, so that the garbage and sewage leaked from the garbage collection truck and the dirt dropped by the garbage collection truck after being flushed with high-pressure gas are accumulated in the garbage collection trough, and the liquid and solid garbage in the garbage collection trough are frozen by the low-temperature cold air in the freezing chamber, so that the garbage can be suppressed from emitting odor, thereby achieving the purpose of significantly suppressing the odor of the garbage transfer workshop.

[0030] 2. The garbage transfer workshop of the present invention is provided with a refrigeration airbag, which can refrigerate the garbage transfer workshop through heat exchange between internal cold air and external hot air. The isolation effect of the refrigeration airbag prevents the cold air inside the airbag from being sucked away by the negative pressure suction device or carried away by the disturbed airflow of the front garbage collection vehicle, thereby ensuring the refrigeration effect of the refrigeration airbag on the driving lane. The refrigeration airbag can also cool by slowly releasing cold air to the outside. The release of cold air can not only improve the refrigeration efficiency of the driving lane, but also allow new cold air to enter the airbag to supplement the cold air inside the refrigeration airbag.

[0031] By refrigerating the garbage transfer workshop, the odor emitted by garbage trucks and garbage in the transfer workshop can be suppressed, and the hot steam in the garbage transfer workshop will liquefy into water droplets when cooled. Some of the odor and smelly floating particles in the workshop will dissolve in the water droplets and fall with the water droplets, thereby further achieving the purpose of deodorizing the transfer workshop.

[0032] In addition, the refrigeration airbag in the present invention is made of soft film material, with high heat exchange efficiency. The low temperature resistant film has good elasticity. At the same time, the cold air in the refrigeration airbag is not completely saturated. The lifting of the front garbage collection truck can drive the deformation of the refrigeration airbag, but the lifting of the truck is not affected. The contact between the refrigeration airbag and the cargo box produces adaptive deformation, which can also ensure that it will not be squeezed.

[0033] 3. The refrigeration airbags provided in the garbage transfer workshop of the present invention have a filling effect on the internal space of the driving lane, thereby reducing the air flow channel in the driving lane. In this way, during the air extraction process of the negative pressure device, the air flow velocity flowing from the driving lane into the garbage dumping isolation room is greater, which can effectively prevent the odor in the driving lane from flowing out.

[0034] 4. The garbage transfer workshop of the present invention has to meet the requirements of the cargo box lifting operation of the front-end garbage transport truck, and the space of the garbage transfer workshop is relatively high (the industry standard is not less than 7.5 meters); while the static height of the garbage transport truck is relatively low (the industry standard is not higher than 4 meters); this space situation allows the refrigeration airbag to be made very large and can store a large amount of cold air. During the low electricity consumption period, the refrigeration airbag can store a large amount of cold air, and the cost-effectiveness is high.

[0035] 5. The freezing chamber and the garbage collection tank in the present invention are an integrated structure, both of which are made of welded steel plates. The garbage liquid cannot penetrate into the steel plates. Therefore, after the garbage collection tank is cleaned, the freezing chamber and the garbage collection tank will not stink.

[0036] 6. The odor suppression method and the garbage transfer workshop of the present invention, wherein the garbage dumping isolation room is a closed space connected to the driving lane, and when the gas in the garbage dumping isolation room is extracted, the compensating airflow outside the garbage dumping isolation room can only enter the garbage dumping isolation room through the driving lane.

[0037] When dumping garbage, a garbage collection truck will generate a recoil airflow, and the recoil airflow has a large air volume and a fast flow rate. The fast speed of the recoil airflow will affect the suction effect of the negative pressure suction device. In the present application, the garbage dumping isolation room is a closed space with negative pressure, which can buffer the recoil airflow generated by the garbage collection truck when dumping garbage. After buffering, the flow rate of the recoil airflow will decrease. After the flow rate of the recoil airflow decreases, it is easy to be sucked away by the negative pressure suction device set in the garbage dumping isolation room. At the same time, the compensating airflow outside the garbage dumping isolation room can only enter the garbage dumping isolation room through the driving lane. The airflow flows unidirectionally from the driving lane to the garbage dumping isolation room, and the odor in the garbage dumping isolation room cannot escape.

[0038] 7. The odor suppression method and the garbage transfer workshop of the present invention, by refrigerating the garbage loading hopper, the odor-producing bacteria attached to the surface of the garbage loading hopper are placed in a low-temperature environment, thereby inhibiting the growth and activity of the odor-producing bacteria, and significantly reducing the odor produced by the fermentation of the bacteria; at the same time, the dirt and sewage attached to the surface of the garbage loading hopper are placed in a low-temperature environment, which can also inhibit the odor of the dirt and sewage. At the same time, when the temperature of the garbage loading hopper is low, the sewage attached to the surface of the garbage loading hopper can also be frozen, so that the sewage remaining on the surface of the garbage loading hopper in the gap between the previous rear-end transfer vehicle and the next rear-end transfer vehicle will not flow out of the garbage loading hopper and pollute the environment.

[0039] 8. The odor suppression method and the garbage transfer workshop of the present invention are such that when a garbage collection truck dumps garbage into the garbage loading hopper disposed at the bottom of the garbage dumping isolation room, the upper door, the left door and the right door can be closed so that the three doors are respectively close to or in contact with the upper side, the left side and the right side of the garbage collection truck, thereby blocking the odorous airflow from flowing from the passage between the garbage collection truck and the wall of the driving lane toward the exit of the driving lane through the doors, thereby further preventing the backwash odorous airflow from escaping.

[0040] 9. The garbage collection trough of the garbage transfer workshop of the present invention has an extension section that exceeds the top of the freezing cavity and extends horizontally toward the middle of the garbage isolation room. Through the extension section, the position where the garbage collection truck dumps the garbage can be close to the upper middle part of the garbage loading hopper, thereby preventing the garbage and sewage dumped by the garbage collection truck from falling to the outside of the garbage loading hopper, and better protecting the cleanliness of the garbage transfer isolation room.

[0047] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0048] In the present embodiment, the method for suppressing odor in a garbage transfer workshop comprises a garbage dumping isolation room 1 and a driving lane 2 connected to the garbage dumping isolation room, wherein the driving lane is a tubular lane, and the method comprises cooling the bottom of the driving lane so that the garbage dropped on the bottom of the driving lane is in a low temperature environment, thereby suppressing the odor emitted by the garbage on the bottom of the driving lane. Cooling and refrigerating the solid and liquid garbage dropped on the bottom of the driving lane can significantly reduce the volatile odor of the garbage; it can also suppress the activity of the bacterial flora contained in the solid and liquid garbage, and reduce the odor generated by bacterial fermentation.

[0049] As an improvement on the above-mentioned embodiment, the odor suppression method of the garbage transfer workshop in this embodiment also includes cooling the garbage loading funnel 8 arranged at the bottom of the garbage dumping isolation room 1, so that the surface of the garbage loading funnel is in a low-temperature environment, thereby inhibiting the odor-producing bacteria and dirt attached to the surface of the garbage loading funnel from generating odor, which can further reduce the amount of odor in the garbage transfer workshop.

[0050] As an improvement to the above embodiment, the odor suppression method of the garbage transfer workshop also includes setting a refrigeration airbag 3 on the top of the driving lane, and the refrigeration airbag cools the internal space of the driving lane to suppress the odor emitted by the garbage truck in the driving lane.

[0051] As an improvement on the above-mentioned embodiment, the garbage dumping isolation room 1 is a closed space connected to the driving lane 2. The odor suppression method of the garbage transfer workshop also includes providing a negative pressure suction device 4 to extract the gas in the garbage dumping isolation room, and making the airflow in the driving lane only flow in one direction from the lane entrance to the garbage dumping isolation room under the action of negative pressure, so as to prevent the odor in the garbage dumping isolation room and the driving lane from escaping from the lane entrance of the driving lane.

[0052] As an improvement to the above embodiment, the temperature of the low temperature environment is below zero degrees. This improvement makes the garbage on the bottom of the driving lane in a low temperature environment below zero degrees, and the odor suppression effect is better.

[0053] As an improvement to the above embodiment, the odor suppression method of the garbage transfer workshop further includes setting an upper door 5 that moves up and down or telescopically on the top of the driving lane, setting a left door 6 that moves left and right or telescopically on the left side of the driving lane, and setting a right door 7 that moves left and right or telescopically on the right side of the driving lane. When the garbage collection vehicle dumps garbage into the garbage loading hopper set at the bottom of the garbage dumping isolation room, the upper door, the left door and the right door are closed, so that the three doors are close to or in contact with the upper side, the left side and the right side of the garbage collection vehicle, respectively, to prevent the odor from escaping from the passage between the garbage collection vehicle and the wall of the driving lane toward the exit of the driving lane. In this way, the air environment outside the garbage transfer workshop can be better protected.

[0054] The garbage transfer workshop according to the odor suppression method of the garbage transfer workshop described in the above embodiment includes a garbage dumping isolation room 1 and a driving lane 2 connected to the garbage dumping isolation room, a refrigeration cavity 10 for carrying a garbage collection truck is arranged at the bottom of the driving lane, the interior of the refrigeration cavity is used to store cold air or cold liquid, and a garbage collection trough 11 is arranged at the top of the refrigeration cavity.

[0055] In a specific implementation, the cold air in the freezing cavity 10 can be circulated internally, and the cold air in the freezing cavity 10 is not discharged to the outside, which is conducive to reducing refrigeration energy consumption. The cold air in the freezing cavity 10 can also be circulated externally. At this time, it is necessary to set exhaust micropores 12 on the freezing cavity 10 so that the cold air in the freezing cavity 10 can be slowly released to the outside, so as to improve the refrigeration efficiency of the garbage transfer workshop. In a specific implementation, a cold storage 13 can be constructed, and cold air is sent into the freezing cavity through the cold storage. The freezing cavity is provided with a cold air inlet 14 for cold air to enter. The cold air temperature output by the cold storage 13 is below 0°, which can achieve the effect of freezing the garbage in the garbage collection tank 11. Of course, the method of using a refrigerator to directly supply cold air to the freezing cavity 10 is not excluded. When the cold air is replaced by cold liquid, the freezing cavity 10 is not provided with exhaust micropores 12, and the cold liquid adopts an internal circulation method.

[0056] In the garbage transfer workshop of the present embodiment, a refrigeration chamber for carrying a garbage collection truck is arranged at the bottom of the driving alley, and a garbage collection trough is arranged on the top of the refrigeration chamber. In this way, the garbage and sewage leaked from the garbage collection truck and the dirt dropped by the garbage collection truck during flushing with high-pressure gas are accumulated in the garbage collection trough. The liquid and solid garbage in the garbage collection trough are frozen by the low-temperature cold air in the refrigeration chamber, thereby suppressing the odor of these garbage, and further achieving the purpose of significantly suppressing the odor of the garbage transfer workshop.

[0057] In addition, after the garbage truck operation is completed, the cold air or cold liquid in the freezing chamber 10 can be discharged to accelerate the melting of ice in the garbage collection trough 11, thereby facilitating the cleaning of the garbage collection trough 11.

[0058] In a specific implementation, a rib plate 15 with ventilation holes may be provided in the freezing cavity to improve the bearing capacity of the freezing cavity 10 and effectively avoid deformation of the cavity.

[0059] As an improvement to the above embodiment, the garbage loading hopper arranged at the bottom of the garbage dumping isolation room has a cavity 16 for accommodating a refrigeration medium around it. The refrigeration medium, which can be cold air or cold liquid, is introduced into the cavity 16 of the refrigeration medium to cool the garbage loading hopper, so that the odorous bacteria or dirt attached to the surface of the garbage loading hopper is placed in a low temperature environment, thereby inhibiting the growth and reproduction of the odorous bacteria and inhibiting the odorous bacteria and dirt from generating odor.

[0060] As an improvement to the above embodiment, the garbage collection trough 11 has an extension section 17 extending beyond the top of the freezing chamber and horizontally extending toward the middle of the garbage isolation room. Through the extension section, the position where the garbage collection truck 9 dumps the garbage can be close to the upper middle of the garbage loading hopper, thereby preventing the garbage and sewage dumped by the garbage collection truck from falling to the outside of the garbage loading hopper, and better protecting the cleanliness of the garbage transfer isolation room.

[0061] As an improvement to the above embodiment, the sides and bottom of the freezing cavity are provided with a heat insulation layer 18, and the top of the freezing cavity is a heat exchange layer. This improvement allows the cold air to exchange heat with the outside world mainly through the top of the freezing cavity, so that the cold air can be used more efficiently to achieve rapid freezing of the garbage dropped into the garbage collection trough 11.

[0062] As an improvement to the above embodiment, the garbage collection chute 11 is an integrated structure with the top of the freezing chamber 10, the front end of the garbage collection chute is a slope structure 111 for the garbage truck to enter and exit smoothly, and the rear end of the garbage collection chute has a step structure 112 for blocking the garbage truck and bearing the impact of the garbage truck. The garbage truck hitting the step structure 112 can quickly and completely discharge the garbage in the cargo box.

[0063] As an improvement to the above embodiment, the garbage transfer workshop further comprises an upper door 5 arranged at the top of the driving lane, a left door 6 arranged at the left side of the driving lane, and a right door 7 arranged at the right side of the driving lane. When the garbage collection vehicle dumps garbage into the garbage loading hopper 8 arranged at the bottom of the garbage dumping isolation room 1, the upper gate, the left door and the right door are closed, so that the three rolling shutters are close to or in contact with the upper side, the left side and the right side of the garbage collection vehicle 9 respectively, so as to block the odor from flowing from the passage between the garbage collection vehicle and the wall of the driving lane toward the exit of the driving lane, so as to prevent the backwash odor generated by the falling garbage from escaping outside the driving lane.

[0064] As an improvement to the above embodiment, a refrigeration airbag 3 is provided at the top of the driving lane. In a specific implementation, the cold air in the refrigeration airbag 3 can be circulated internally, and the cold air in the refrigeration airbag 3 is not discharged to the outside, which is beneficial to reducing refrigeration energy consumption. The cold air in the refrigeration airbag 3 can also be circulated externally. In this case, it is necessary to provide a plurality of micropores 31 on the refrigeration airbag 3 for slowly releasing the cold air, so that the cold air in the refrigeration airbag 3 can be slowly released to the outside, thereby improving the refrigeration efficiency of the garbage transfer workshop. In a specific implementation, the cold air can be supplied to the refrigeration airbag 3 through the cold storage 13.

[0065] As an improvement to the above embodiment, a refrigeration air bag 3 is also provided on the top of the garbage dumping isolation room.

[0066] A pull rope can be provided on the refrigeration airbag 3, and connectors connected to the pull rope can be provided on the top of the garbage dumping isolation room and the driving lane, respectively. The installation of the refrigerator airbag can be completed by connecting the pull rope to the connector. Of course, in different embodiments, the refrigeration airbag can also be installed in other ways.

[0067] The improvement cools the garbage transfer workshop through the refrigeration airbag 3, which can suppress the odor emitted by the garbage truck and garbage in the transfer workshop, and the hot steam in the garbage transfer workshop will liquefy into water droplets when cooled, and some of the odor and smelly floating particles in the workshop will dissolve in the water droplets and fall with the water droplets, thereby further achieving the purpose of deodorizing the transfer workshop.

[0068] As an improvement to the above embodiment, the refrigeration airbag 3 is made of a low temperature resistant and flexible film, and specifically the refrigeration airbag can be made of a PE film. The PE film can also maintain good toughness at low temperatures. When the garbage truck dumps garbage, the cargo box of the garbage truck tilts upward and squeezes and contacts the refrigeration airbag 3. The good elasticity and toughness of the PE film can avoid the problem of rupture during the squeezing and contacting process.

[0069] As an improvement to the above embodiment, the garbage transfer workshop also includes a negative pressure suction device 4 for extracting gas from the garbage dumping isolation room. The negative pressure suction device 4 includes a negative pressure delivery pipe 41 and a negative pressure air inlet 42 connected to the negative pressure delivery pipe 41. The odor in the garbage dumping isolation room 1 and the driving lane 2 is extracted and sent to the deodorization device by the negative pressure suction device 4, which can avoid the problem of direct emission of odor from the garbage transfer workshop to pollute the atmosphere. In addition, the filling of the cavity of the driving lane 2 by the refrigeration airbag 3 and the front garbage collection vehicle 9 reduces the cross-section of the airflow channel, which can increase the flow speed of the airflow in the driving lane 2. The air flows at a higher speed from the inlet side of the driving lane 2 to the flow channel of the garbage dumping isolation room 1, which can better prevent the odor from diffusing outward from the inlet of the driving lane 2.

[0070] As an improvement to the above-mentioned embodiment, the garbage transfer workshop further includes a negative pressure suction air intake structure 19 arranged at the upper door edge, the left door edge and the right door edge and connected to the negative pressure suction device. The negative pressure suction air intake structure 19 can specifically be composed of an air pipe arranged along the door edge and air intake holes evenly arranged on the air pipe. When the front-end garbage collection truck 9 dumps garbage, the upper door, the left door and the right door are close to or in contact with the front-end garbage collection truck 9. The negative pressure suction air intake structure 19 performs negative pressure suction on the part where the door and the front-end garbage collection truck 9 match, which can further prevent the odor from escaping from the gap between the door and the front-end garbage collection truck 9.

[0071] As an improvement to the above embodiment, a plurality of open containers 20 are provided in the laneway, and the containers are filled with plant deodorizing liquid. By providing containers filled with plant deodorizing liquid in the laneway, the plant deodorizing liquid can absorb and purify the odor in the laneway, and the aroma volatilized by the plant deodorizing liquid can also suppress the odor in the laneway, thereby further improving the air quality in the laneway.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
