Description

Deodorization method for garbage transfer station and garbage transfer station TECHNICAL FIELD

[0001] The present application relates to the technical field of household garbage transfer and transportation, and particularly relates to a deodorization method for a garbage transfer station and the garbage transfer station. BACKGROUND

The patent sets up a driving lane, a high-pressure air jet device, and a negative pressure air suction device, which can clean the vehicle body with high-pressure gas and remove the odor in the transfer station through the negative pressure air suction device.

[0003] The garbage stored in the front-end garbage collection vehicle contains a large amount of sewage, which is likely to seep out of the garbage truck box during transportation. Meanwhile, when working on a rainy day, the sewage contaminated by the vehicle body will also drip from the garbage truck body. Since a large number of front-end garbage collection vehicles will enter and exit the driving lane during the working period, a large amount of garbage and sewage will be accumulated in the driving lane, which will cause the driving lane to emit odor. In addition, when the front-end garbage collection vehicle performs gas flushing in the driving lane, the flushed dirt will also contaminate the driving lane, causing the driving lane to emit odor.

[0004] In addition, in the summer high-temperature weather, the front-end garbage collection vehicle and the garbage itself will emit a large amount of odor, and if the odor emitted by the front-end garbage collection vehicle and the garbage is not inhibited, the driving lane will also emit odor.

[0005] In addition, when the garbage collection vehicle dumps garbage into the garbage loading hopper arranged at the bottom of the garbage dumping isolation room, the garbage falling will produce a strong backflow odor flow, which has a large speed and may escape from the driving lane. In addition, dirt and odor-causing bacteria groups will adhere to the surface of the garbage loading hopper, which will continuously emit odor, so the backflow odor flow and the odor sources adhering to the surface of the garbage loading hopper also need to be inhibited.

[0027] Further, a plurality of open containers are arranged in the travel lane, and the containers contain plant deodorizing liquid. Beneficial effects

[0028] 1. The garbage transfer station and the deodorization method thereof, which refrigerate the bottom of the travel lane, specifically by arranging a freezing cavity for bearing the garbage collection truck at the bottom of the travel lane, and arranging a garbage collection tank at the top of the freezing cavity, so that the garbage and sewage leaked from the garbage collection truck and the dirt dropped by the high-pressure gas flushing the garbage collection truck are accumulated in the garbage collection tank, and the liquid and solid garbage in the garbage collection tank are frozen by the low-temperature cold air in the freezing cavity, thereby inhibiting the emission of odor from the garbage, and achieving the purpose of inhibiting the odor emission of the garbage transfer station.

[0029] 2、The garbage transfer station of the present application, by setting the refrigeration air bag, the refrigeration air bag can be through the heat exchange between the internal cold air and the external hot air to refrigerate the garbage transfer station. The isolation effect of the refrigeration air bag avoids the cold air in the air bag being sucked away by the negative pressure air suction device or being taken away by the disturbance airflow of the front-end garbage collection vehicle, ensuring the refrigeration effect of the refrigeration air bag on the driving lane. The refrigeration air bag can also refrigerate by slowly releasing cold air to the outside. The released cold air not only improves the refrigeration efficiency of the driving lane, but also allows new cold air to enter the air bag, realizing the replenishment of the cold air in the refrigeration air bag.

[0030] By refrigerating the garbage transfer station, the odor emission of the garbage truck and the garbage in the transfer station can be inhibited, and the hot steam in the garbage transfer station will be liquefied into water droplets when it is cooled. Part of the odor and odor floating particles in the station will dissolve in the water droplets and fall with the water droplets, thereby further achieving the purpose of deodorizing the transfer station.

[0031] In addition, the refrigeration air bag in the present application is made of soft film material with high heat exchange efficiency. The low-temperature resistant film has good elasticity, and the cold air in the refrigeration air bag is not completely saturated. The lifting of the truck box of the front-end garbage collection vehicle can drive the deformation of the refrigeration air bag, but the lifting activity of the truck box is not affected. The self-adaptive deformation of the refrigeration air bag and the truck box can also ensure that it will not be squeezed.

[0032] 3、The refrigeration air bag of the garbage transfer station of the present application has a filling effect on the internal space of the driving lane, thereby reducing the airflow channel in the driving lane. Thus, during the air suction process of the negative pressure device, the airflow speed 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.

[0033] 4、The garbage transfer station of the present application has a relatively high space (industry standard not less than 7.5 meters) to meet the requirements of the lifting operation of the truck box of the front-end garbage transport vehicle. The static height of the garbage transport vehicle is relatively low (industry standard not higher than 4 meters). This space condition makes the refrigeration air bag large and can store a large amount of cold air. The refrigeration air bag can store a large amount of cold air during the low electricity period, and the cost-effectiveness is high.

[0034] 5、The refrigeration cavity and the garbage collection tank in the present application are integrated structures made of steel plates. The garbage liquid cannot penetrate into the steel plate, so after the garbage collection tank is cleaned, the refrigeration cavity and the garbage collection tank will not emit odor.

[0035] 6、The deodorization method of the garbage transfer station of the present application and the garbage transfer station, the garbage dumping isolation room is a closed space communicating with the driving lane. When the gas in the garbage dumping isolation room is extracted, the compensation airflow outside the garbage dumping isolation room can only enter the garbage dumping isolation room through the driving lane.

[0036] The garbage collection vehicle generates backflow air flow when dumping garbage, and the backflow air flow has large air flow and fast flow rate. The fast speed of the backflow air flow affects the air suction effect of the negative pressure air suction device. The garbage dumping isolation room in the application is a closed space with negative pressure, which can buffer the backflow air flow generated when the garbage collection vehicle dumps garbage. After buffering, the flow rate of the backflow air flow will decrease, and the backflow air flow is easily sucked away by the negative pressure air suction device arranged in the garbage dumping isolation room. Meanwhile, the compensation air flow outside the garbage dumping isolation room can only enter the garbage dumping isolation room through the driving lane, and the air flow flows from the driving lane to the garbage dumping isolation room in one direction, so that the odor in the garbage dumping isolation room cannot escape.

[0037] 7、The garbage transfer station and the odor suppression method thereof in the application, by refrigerating the garbage loading funnel, the odor-producing bacteria attached to the surface of the garbage loading funnel are in a low-temperature environment, so that the growth and reproduction of the odor-producing bacteria and the activity of the odor-producing bacteria can be inhibited, and the odor produced by the fermentation of the bacteria can be significantly reduced. Meanwhile, the dirt and sewage attached to the surface of the garbage loading funnel are also in a low-temperature environment, so that the odor produced by the dirt and sewage can also be inhibited. When the refrigeration temperature of the garbage loading funnel is relatively low, the sewage attached to the surface of the garbage loading funnel can also be frozen, so that the sewage remaining on the surface of the garbage loading funnel during the interval between the front and rear transfer vehicles will not flow out of the garbage loading funnel and pollute the environment.

[0038] 8、The garbage transfer station and the odor suppression method thereof in the application, when the garbage collection vehicle dumps garbage into the garbage loading funnel arranged at the bottom of the garbage dumping isolation room, the upper door, the left door and the right door are closed, and 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. The odor flow is blocked by the doors and cannot flow from the channel between the garbage collection vehicle and the driving lane wall to the driving lane outlet, so that the backflow odor flow can be further prevented from escaping.

[0039] 9、The garbage transfer station in the application, the garbage collection tank has an extension section extending horizontally from the top of the refrigeration cavity to the middle of the garbage isolation room. The position where the garbage collection vehicle dumps garbage can be close to the middle upper part of the garbage loading funnel through the extension section, so that the garbage and sewage dumped by the garbage collection vehicle can be prevented from falling outside the garbage loading funnel, and the cleanliness of the garbage transfer isolation room can be better protected.
