The garbage cleaning station is a compression type garbage cleaning station, and three compression type garbage boxes are arranged in the garbage cleaning station, namely three target objects 9 and three target positions 10 are arranged in the garbage cleaning station. The ozone deodorization system for the garbage cleaning station comprises a power supply 6, a control unit 1, a PLC (programmable logic controller), an odor gas sensor 2, an object sensing unit 3 and an object sensing unit, wherein the odor gas sensor 2 adopts a hydrogen sulfide concentration sensor and an ammonia concentration sensor, and the object sensing unit 3 adopts an infrared sensor as shown in figure 2. The ozone deodorization system for the garbage cleaning station is not only suitable for the compression type garbage cleaning station, but also suitable for other types of garbage cleaning stations, such as a hanging building type and the like.
Wherein, 220V alternating current power supply is selected for the power 6, and can be converted into 24V low-voltage power supply through the power supply module. The control unit 1 is connected with an interface of an ozone supply unit 4, and provides a concentration control signal of 4mA-20mA and an equipment starting signal for the ozone supply unit 4, and the ozone supply unit 4 comprises an ozone generating device and an airflow mixer.

The three target positions 10 are respectively provided with an infrared sensor for judging whether the current dustbin enters an operation state or not.
The control unit 1 controls the opening and closing of the electromagnetic valve (control valve 52) to control the on-off of the ozone feeding pipeline, so that when only a part of stations have the dustbin to work, the feeding pipeline is selectively opened and closed to feed ozone. The electromagnetic valve is integrated in the valve group box and arranged close to the ozone generating device, so that the ozone generating device is convenient to connect pipelines, install and maintain. The pipeline and the electromagnetic valve are required to be corrosion-resistant, the pipeline has a certain heat preservation effect, and the thermal decomposition loss of ozone is reduced.
The display 81 and indicator lights 82 may display the operating status for alerting the operator of the system operating status.

The control logic and method of operation of the ozone deodorization system for a refuse cleaning station is described below.
The garbage cleaning station is divided into an operating state and a non-operating state. And when the garbage station is in a non-operation state, the garbage can in the garbage station stores garbage, and the garbage can is closed. When the concentration of the odor in the garbage can is too high and the sealing of the garbage can is poor, a small amount of odor can be dispersed into the ambient air. The elimination of the monitoring result by the odorous gas sensor 2 is required at this time, and the ozone deodorization system for the garbage cleaning station is provided with an environment monitoring mode for coping with the situation. When the garbage bin of the garbage station enters an operation state, the garbage bin is opened, and a large amount of odor is emitted to the environment. In order to rapidly eliminate a large amount of generated odor, high-concentration ozone needs to be prepared in a short time according to the ambient temperature and humidity and preset parameters, and the ozone deodorization system for the garbage cleaning station is provided with a starting operation mode according to the situation.
The specific operation method is as follows:
1. after the system is installed, the power supply is switched on, the control unit 1 automatically operates, and the infrared sensor (the object sensing unit 3) detects whether the dustbin enters a throwing operation state or not.
2. When the infrared sensor does not catch dustbin operation characteristic, control unit 1 gets into the environmental monitoring mode, and under this mode, hydrogen sulfide sensor and ammonia sensor continue to gather gas concentration in the environment, and when concentration reached the setting value, control unit 1 automatic calculation required ozone input concentration gets rid of the foul smell in the environment.
3. In the environment monitoring mode, the control unit 1 enters a start-up operation state whenever the operation characteristics of the dustbin are captured.
4. In the starting operation state, according to the conditions of current temperature, humidity and the like, the control unit 1 starts the ozone supply unit 4 to realize the preparation and mixing of ozone, and a large amount of odor generated in a short time due to the opening of the dustbin in the operation process is eliminated at fixed points.
5. When the infrared sensor catches that the operation characteristics of the dustbin disappear and the operation is finished, the system enters the environment monitoring mode again, and the comprehensive water feeding level and the feeding amount are calculated according to the concentration measured by the odorous gas, as shown in fig. 5.
The above description is only exemplary of the utility model and should not be taken as limiting the scope of the utility model, so that the utility model is intended to cover all modifications and equivalents of the embodiments, which may be included within the spirit and scope of the utility model. In addition, the technical features and the technical schemes, and the technical schemes can be freely combined and used.
