Description

Technical Field

[0001] This utility model relates to the technical field of municipal solid waste incineration equipment, and in particular to a waste receiving, storage and pretreatment system. Background Technology

[0002] With the acceleration of urbanization, traditional landfill and extensive incineration have exposed numerous problems, such as leachate pollution of groundwater, emission of harmful gases, and low calorific value utilization. In existing technologies, the open design of waste receiving and storage often leads to odor diffusion and waste of combustible gases, as well as leachate leakage, which easily pollutes the environment. Insufficient pretreatment before incineration also affects combustion efficiency. There is an urgent need for systematic process optimization to achieve a closed, efficient, and clean process for waste receiving, storage, and pretreatment. Utility Model Content

[0003] To address the shortcomings of the aforementioned technologies, this utility model provides a waste receiving, storage, and pretreatment system, including a waste storage tank, a leachate collection tank, and a sealed waste receiving channel. The sealed waste receiving channel is connected to the waste storage tank, and the leachate collection tank is connected to the bottom of the waste storage tank. The sealed waste receiving channel is equipped with a leak-proof purification device, which includes a purification air intake chamber, a purification exhaust chamber, an exhaust pipe, several negative pressure fans, and a spraying mechanism. End sealing doors are provided at the entrance of the sealed waste receiving channel and at the connection between the sealed waste receiving channel and the waste storage tank. The purification air intake chamber and the purification exhaust chamber are both located above the sealed waste receiving channel and are connected by several negative pressure fans. A negative pressure fan for air intake is located at the top of the purification air intake chamber, and the exhaust pipe is fixedly installed on the purification exhaust chamber. The spraying mechanism is located inside the sealed waste receiving channel near the entrance.

[0004] Using the above technical solution, a leak-proof purification device is installed, including a purification air intake chamber, a purification exhaust chamber, an exhaust pipe, several negative pressure fans, and a spray mechanism. During garbage reception and storage, the end sealing door at the entrance of the sealed garbage receiving channel opens, and the garbage truck enters the channel. Afterward, the end sealing door at the entrance closes, and the end sealing door at the connection point with the garbage storage pool opens, allowing the garbage truck to unload the garbage and pour it into the garbage storage pool. Then, the end sealing door at the connection point closes, and all negative pressure fans in the purification air intake chamber, purification exhaust chamber, and sealed garbage receiving channel are activated, allowing clean air to enter from the outside. The garbage truck sequentially enters the purification air intake chamber and the sealed garbage receiving channel. The odor in the channel is discharged into the purification exhaust chamber, and finally the odor is discharged into the combustion furnace through the exhaust pipe of the exhaust chamber. After the odor in the channel is replaced, the garbage truck starts and runs under the spraying mechanism for rinsing to clean the residual leachate in the hopper. After rinsing, the end sealing door at the entrance of the sealed garbage receiving channel is opened, and the garbage truck can drive away directly. The garbage receiving process is completely sealed, and there is no odor leakage or diffusion when the garbage enters and exits. At the same time, there is no leachate dripping when the garbage truck leaves.

[0005] A further feature of this invention is that a central sealing door is provided in the middle of the sealed waste receiving channel, and a connecting pipe is provided on the side walls on both sides of the central sealing door, with a one-way air valve at one end of the connecting pipe.

[0006] By adopting the above technical solution, since a middle sealing door is provided in the middle of the sealed garbage receiving channel, and a connecting pipe is provided on the side wall of the sealed garbage receiving channel on both sides of the middle sealing door, and a one-way air valve is provided at one end of the connecting pipe, after the sealed garbage receiving channel is ventilated and the garbage truck runs under the spraying mechanism, the middle sealing door is locked and closed, and then the spraying mechanism is started to clean the garbage truck. This can prevent water mist from filling the entire sealed garbage receiving channel. After the end sealing door is opened and the garbage truck is driven away, the water mist in the channel where the spraying mechanism is located can be removed. The connecting pipe and one-way valve can ensure the stability of the air pressure in the sealed garbage receiving channel on the side of the middle sealing door.

[0007] A further feature of this invention is that a sewage collection tank is provided below the spraying mechanism, and the sewage collection tank is connected to the leachate tank via a connecting pipe.

[0008] With the above technical solution, since a sewage collection tank is provided below the spraying mechanism, and the sewage collection tank is connected to the leachate tank through a connecting pipe, the sewage containing leachate washed down by the garbage truck can be collected through the sewage collection tank, and then the sewage can be transferred to the leachate tank through the connecting pipe for subsequent treatment.

[0009] A further feature of this invention is that a leachate purification tank is provided on one side of the sealed garbage receiving channel, and the spraying mechanism is connected to the leachate purification tank via a water pump and a connecting pipe.

[0010] By adopting the above technical solution, since a leachate purification tank is provided on one side of the closed garbage receiving channel, and the spraying mechanism is connected to the leachate purification tank through a water pump and connecting pipe, the leachate is treated by the sewage purification station and the water is reused. The treated water is transferred to the leachate purification tank for storage and used for spraying and cleaning garbage trucks, further enhancing the recycling of liquid waste.

Detailed Implementation

[0014] like Figure 1-2 As shown, a waste receiving, storage, and pretreatment system includes a waste storage tank 1, a leachate collection tank 2, and a closed waste receiving channel 3. The closed waste receiving channel is connected to the waste storage tank, and the leachate collection tank is connected to the bottom of the waste storage tank. The closed waste receiving channel is equipped with a leak-proof purification device 4, which includes a purification air intake chamber 5, a purification exhaust chamber 6, an exhaust pipe 7, several negative pressure fans 8, and a spraying mechanism 9. End sealing doors 10 are provided at the entrance of the closed waste receiving channel and at the connection between the closed waste receiving channel and the waste storage tank. The purification air intake chamber and the purification exhaust chamber are both located above the closed waste receiving channel and are connected by several negative pressure fans. The top of the purification air intake chamber is equipped with a negative pressure fan for air intake. The exhaust pipe is fixedly installed on the purification exhaust chamber. The spraying mechanism is located inside the closed waste receiving channel near the entrance.

[0015] The system is equipped with a leak-proof purification device, including a purification air intake chamber, a purification exhaust chamber, an exhaust pipe, several negative pressure fans, and a spray system. During garbage reception and storage, the end sealing door at the entrance of the sealed garbage receiving channel opens, and the garbage truck 18 enters the channel. Afterward, the end sealing door at the entrance closes, while the end sealing door at the connection point with the garbage storage pool opens, allowing the garbage truck to unload and dump the garbage into the storage pool. Then, the end sealing door at the connection point closes, and all negative pressure fans in the purification air intake chamber, purification exhaust chamber, and sealed garbage receiving channel are activated, allowing clean air to enter sequentially from the outside. The garbage truck enters the purification air intake chamber and the sealed garbage receiving channel. The odor in the channel is discharged into the purification exhaust chamber, and finally the odor is discharged into the combustion furnace through the exhaust pipe of the exhaust chamber. After the odor in the channel is replaced, the garbage truck starts and runs to the spray mechanism for washing to clean the residual leachate in the hopper. After washing, the end sealing door at the entrance of the sealed garbage receiving channel is opened, and the garbage truck can drive away directly. The garbage is treated in a completely sealed manner, and there is no odor leakage or diffusion when the garbage enters and exits. At the same time, there is no leachate dripping when the garbage truck leaves.

[0016] The sealed waste receiving channel is provided with a middle sealing door 11 in the middle position. A connecting pipe 12 is provided on the side wall of the sealed waste receiving channel on both sides of the middle sealing door. One end of the connecting pipe is provided with a one-way air valve 13.

[0017] Because the sealed garbage receiving channel has a central sealing door, and a connecting pipe is installed on the side walls on both sides of the central sealing door, with a one-way valve at one end of the connecting pipe, after the sealed garbage receiving channel is ventilated and the garbage truck runs under the spraying mechanism, the central sealing door is locked and then the spraying mechanism is started to clean the garbage truck. This can prevent water mist from filling the entire sealed garbage receiving channel. After the end sealing door is opened and the garbage truck leaves, the water mist in the channel where the spraying mechanism is located can be removed. The connecting pipe and one-way valve can ensure stable air pressure in the sealed garbage receiving channel on the side of the central sealing door.

[0018] A sewage collection tank 14 is provided below the spraying mechanism, and the sewage collection tank is connected to the leachate tank through a connecting pipe 15.

[0019] Because a sewage collection tank is located below the spraying mechanism, and the sewage collection tank is connected to the leachate tank through a connecting pipe, the sewage containing leachate washed down by the garbage truck can be collected through the sewage collection tank, and then transferred to the leachate tank through the connecting pipe for subsequent treatment.

[0020] A leachate purification tank 16 is provided on one side of the enclosed waste receiving channel, and the spraying mechanism is connected to the leachate purification tank through a water pump 17 and a connecting pipe.

[0021] Since a leachate purification tank is provided on one side of the closed garbage receiving channel, the spraying mechanism is connected to the leachate purification tank through a water pump and connecting pipe. After the leachate is treated by the sewage purification station, the water is reused. The treated water is transferred to the leachate purification tank for storage and used for spraying and cleaning garbage trucks, further enhancing the recycling of liquid waste.
