Description

Technical Field

[0001] The present invention relates to the field of air treatment technology, and in particular to an intelligent air treatment system for a garbage room. Background Art

[0002] Garbage rooms are places used for centralized storage and management of garbage. They are more common in communities, public places and other areas. With the development of cities, garbage has increased rapidly, and the number of garbage rooms has increased dramatically. The accumulation and fermentation of garbage will produce a large amount of odorous gases. These odors not only have a serious impact on the living environment, but may also be harmful to human health. At the same time, the air circulation in the garbage room is poor, the air quality is poor, and it is easy to breed bacteria and viruses, further aggravating the deterioration of the environment. However, traditional garbage rooms face many environmental problems that need to be solved during operation. On the one hand, traditional ventilation systems often use simple mechanical exhaust methods. Although they can expel some dirty air to a certain extent, this method cannot effectively filter and purify the fresh air introduced from the outside, resulting in difficulty in ensuring the quality of the fresh air. On the other hand, the existing air treatment system lacks an efficient heat recovery mechanism. During the exhaust process, a large amount of heat carried by the indoor air is directly discharged to the outside, resulting in serious waste of energy. In addition, most traditional systems do not have intelligent control functions and cannot automatically adjust the operating status according to the actual air quality and environmental parameters in the garbage room. Frequent manual intervention is required, which not only increases the labor intensity of the staff, but also makes it difficult to achieve precise environmental control. In terms of deodorization, traditional deodorization methods usually use spraying deodorants or setting simple filtering devices. The deodorization effect of these methods is limited and cannot fundamentally solve the odor problem in the garbage room. Moreover, the equipment selection and configuration of traditional systems are often not targeted and cannot be flexibly adjusted according to the actual area and usage needs of different garbage rooms, resulting in low system operation efficiency and high energy consumption.

[0003] To sum up, the existing garbage room air treatment system has obvious deficiencies in ventilation and purification effect, energy utilization efficiency, intelligent control level and deodorization ability. There is an urgent need for an intelligent air treatment system that can effectively solve the above problems. Summary of the Invention

[0014] Compared with the existing technology, the present invention provides a smart air treatment system for garbage rooms, which has the following beneficial effects: 1. The intelligent air treatment system of the garbage room has a good ventilation and purification effect through the setting of the primary filter. The fresh air is filtered by the primary filter before entering the garbage room, so that the fresh air is clean air when it enters the garbage room, thereby achieving a good ventilation and purification effect.

[0015] 2. The intelligent air treatment system of the garbage room has the effect of improving energy utilization efficiency through the setting of the fresh air heat exchanger module. The setting of the fresh air heat exchanger module can realize the heat exchange between the fresh air and the air in the garbage room. For example, when the air conditioner is turned on to cool down the garbage room and the fresh air heat exchanger module draws the internal cold air out, the drawn cold air can lower the fresh air temperature through the heat exchange of the heat exchanger, which can reduce the loss of air conditioning cooling effect and reduce the air conditioning cooling power, thereby achieving the effect of improving energy utilization efficiency.

[0016] 3. The intelligent air treatment system in the garbage room has a high level of intelligent control through the setting of the intelligent control system. The intelligent control system automatically adjusts the system operation mode and parameters by collecting parameters such as temperature and air quality in real time, realizes precise environmental control, reduces manual intervention, and improves management efficiency. The remote monitoring and control of the system is realized through the Internet of Things technology. Managers can check the system operation status and the air quality in the garbage room anytime and anywhere, and make timely adjustments and management.

[0017] 4. The intelligent air treatment system of the garbage room has a good deodorizing effect through the coordinated setting of the fresh air heat exchange module and the internal circulation photocatalyst deodorization module. The internal circulation photocatalyst deodorization module circulates and deodorizes in the closed garbage room, which can greatly reduce the odor in the garbage room. When the air deodorized by the internal circulation photocatalyst deodorization module is discharged, it is also filtered and deodorized again through the external circulation photocatalyst filter inside the fresh air heat exchange module. Since the external circulation photocatalyst filter performs secondary filtration, the maximum processing load is low, so that the number of photocatalytic active sites is sufficient, which can significantly improve the air quality.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-3 A smart air treatment system for a garbage room is applied to a garbage room 1 and includes a fresh air heat exchanger module 2, an air conditioning module 3, an internal circulation photocatalyst deodorization module 4, and an intelligent control system 5. The fresh air heat exchanger module 2 includes a housing 201. An outdoor fresh air inlet 202 and an indoor air inlet 203 are fixedly installed on the outside of one end of the housing 201. An outdoor exhaust outlet 204 and an indoor air supply outlet 205 are fixedly installed on the outside of the other end of the housing 201. A heat exchanger 206 and a partition 207 are fixedly installed inside the housing 201. The heat exchanger 206 and the partition 207 divide the interior of the housing 201 into an external air filter chamber 208, an internal air filter chamber 209, an exhaust chamber 210, and an air supply chamber 211. A primary filter 212 is fixedly installed inside the external air filter chamber 208, an external circulation photocatalyst filter 213 is fixedly installed inside the internal air filter chamber 209, an exhaust fan 214 is fixedly installed inside the exhaust chamber 210, and a supply fan 215 is fixedly installed inside the supply air chamber 211. A fresh air check valve 216 is fixedly installed at the outer end of the outdoor fresh air outlet 202, and an exhaust check valve 217 is fixedly installed at the outer end of the outdoor exhaust outlet 204. The air conditioning module 3 includes an air conditioning indoor unit 301 and an air conditioning outdoor unit 302. The air conditioning indoor unit 301 is installed between the heat exchanger 206 and the supply fan 215. The internal circulation photocatalyst deodorization module 4 includes an internal circulation photocatalyst filter 401 and a fan box 402.

[0022] Specifically, the heat exchanger 206 is a plate heat exchanger 206, which is composed of a series of stacked metal sheets with a certain corrugated shape. Thin rectangular channels are formed between the plates, and heat is exchanged through the plates. It has the advantages of high heat transfer efficiency, small footprint, and easy disassembly and cleaning. The photocatalyst filter uses nano-titanium dioxide as the main raw material, and combines nanotechnology to make it evenly attached to the surface of the carrier. Under the irradiation of light sources such as sunlight, fluorescent lamps, and ultraviolet light, the photocatalyst excites electrons in the valence band to jump to the conduction band, and generates corresponding holes in the valence band, generating active oxygen and hydroxyl free radicals with extremely strong oxidizing effects. These free radicals can oxidize and decompose harmful organic matter, pollutants, odors, bacteria, etc., such as formaldehyde, benzene, xylene, ammonia, TVOC, into harmless carbon dioxide and water, thereby achieving the purposes of purifying the air, decomposing harmful organic matter, sterilizing and disinfecting.

[0023] The garbage room 1 is a sealed structure with a doorway. The fresh air heat exchanger module 2 is installed in the middle of the top surface of the garbage room 1, the internal circulation photocatalyst deodorization module 4 is installed on the inner wall of the garbage room 1, and the intelligent control system 5 is installed on the outside of the garbage room 1 near the doorway.

[0024] Specifically, the fresh air heat exchanger module 2 is located directly above the garbage pile, and the distance between the internal circulation photocatalyst deodorization module 4 and the ground can be selected between 1.5 meters and 2 meters, so that it can be easily detected without being submerged by garbage. The intelligent control system 5 is installed outside the door to facilitate the staff to check the situation inside the garbage room 1 before opening the door.

[0025] An air intake pipe 6 is arranged between the fresh air check valve 216 and the air outside the garbage room 1. The fresh air check valve 216 allows the external air to flow into the fresh air heat exchanger module 2 in one direction from the air intake pipe 6. An exhaust pipe 7 is arranged between the exhaust check valve 217 and the air outside the garbage room 1. The exhaust check valve 217 allows the gas inside the fresh air heat exchanger module 2 to flow out of the garbage room 1 in one direction through the exhaust pipe 7.

[0026] Specifically, when the fresh air heat exchanger module 2 is working, the air outside the garbage room 1 is drawn into the shell 201 through the air inlet pipe 6. When the fresh air heat exchanger module 2 is working, the treated air is discharged to the outside of the garbage room 1 through the exhaust pipe 7. After the fresh air and the air in the garbage room 1 enter the fresh air heat exchanger module 2 at the same time, heat exchange can be achieved through the heat exchanger 206.

[0027] The outer end of the indoor air inlet 203 is installed with an air intake elbow 8 with its port facing downward, and the outer end of the indoor air supply outlet 205 is installed with an air supply elbow 9 with its port facing downward, and a distance is set between the lower end of the air intake elbow 8 and the lower end of the air supply elbow 9.

[0028] Specifically, the air intake elbow 8 and the air supply elbow 9 respectively extract and supply air from both sides above the garbage pile, so that the air flow circulates above the garbage pile, achieving a large-scale disturbance of the air flow to achieve the effect of comprehensively removing odor.

[0029] The air conditioner outdoor unit 302 is installed outside the garbage room 1, and a cooling copper pipe, a drainage pipe and a connecting line are provided between the air conditioner indoor unit 301 and the air conditioner outdoor unit 302.

[0030] Specifically, the air conditioner indoor unit 301 is installed in the channel where fresh air enters the garbage room 1. When the air conditioner outdoor unit 302 is working, the temperature of the air conditioner indoor unit 301 is reduced, which can reduce the temperature of the air flowing through the air conditioner indoor unit 301, thereby reducing the temperature of the fresh air when it enters the garbage room 1 to cool the garbage room 1.

[0031] An air inlet hole is provided on the side of the fan box 402 close to the garbage dump, and the length and width dimensions of the air inlet hole are smaller than the length and width dimensions of the inner circulation photocatalyst filter 401. The inner circulation photocatalyst filter 401 is installed on the outside of the air inlet hole. A blower is installed inside the fan box 402, and the blower is provided with an air intake port and an air exhaust port. The air exhaust port is fixedly installed at the bottom of the fan box 402 through a flange and passes through the bottom surface of the box. The air intake port is located inside the fan box 402 and faces the inner circulation photocatalyst filter 401.

[0032] Specifically, when the blower is working, the air in the garbage room 1 is filtered through the internal circulation photocatalyst filter 401 and then drawn into the fan box 402, and then discharged into the garbage room 1 from the bottom of the fan box 402, so as to realize the circulation and filtration of the air in the garbage room 1 and achieve the effect of deodorization and sterilization.

[0033] The air conditioner indoor unit 301 can be removed from the fresh air heat exchange module 2, so that the fresh air heat exchange module 2 no longer has the cooling function and is mainly used for deodorization and ventilation of the oil separator room and the sewage pump room.

[0034] Specifically, the oil separator room is mainly used to treat oily wastewater, separating oil and water by physical or chemical methods to prevent grease from entering the drainage pipes and sewage treatment systems. The function of the sewage pump room is to raise the water level of the sewage and lift the sewage from a low place to a high place so that the sewage can be smoothly discharged into the municipal sewage network or sewage treatment plant. The equipment inside the oil separator room and the sewage pump room is generally automatically operated, with few workers entering and exiting, and the high and low temperatures inside the oil separator room and the sewage pump room have little effect on the generation of odor. Therefore, there is no need to adjust the temperature in the oil separator room and the sewage pump room, and the fresh air heat exchanger module 2 installed in the oil separator room and the sewage pump room can remove the air conditioner indoor unit 301.

[0035] The intelligent control system 5 includes a liquid crystal control screen, a sensor module, a power module, a data processing module and a communication module. The sensor module is provided with a temperature sensor, an air quality detection sensor and a damper actuator. The power module is provided with a frequency converter and a GAU control board. The data processing module is used to monitor and collect data and control the status of the unit. The communication module is provided with a 485 communication interface and a network interface. The communication module is connected to the fresh air heat exchange module 2, the air conditioning module 3 and the internal circulation photocatalyst deodorization module 4 through the 485 communication interface.

[0036] Specifically, the LCD control screen can display the air condition in the garbage room 1 in real time, the temperature sensor is used to detect the temperature in the garbage room 1, the air quality detection sensor is used to detect the air quality parameters in the garbage room 1, such as the concentration of odorous gases, etc., the sensor module is used to collect data from each sensor, the air valve actuator is used to control the opening and closing of the fresh air valve and the exhaust valve, the power module provides power for each component of the system, the frequency converter is used to control the speed of the fan, the data processing module is used to process and analyze the collected data, the 485 communication interface and the network interface are used to realize the communication connection between the system and external equipment, and can be connected to the centralized control platform to facilitate centralized viewing and adjustment by management personnel.

[0037] When in use, the garbage room intelligent air treatment system has multiple operating modes to adapt to different environmental requirements: Ventilation (heat exchange) mode: Normally, in this mode, the exhaust fan 214 and the supply fan 215 are turned on at the same time. The outdoor air and the exhaust air are heat-exchanged in the heat exchanger 206 and then sent into the room. On the one hand, the fresh air in the garbage room 1 is replenished to improve the air environment in the garbage room 1. On the other hand, the heat of the indoor air is recovered to achieve clean, efficient and energy-saving. At the same time, the internal circulation photocatalyst deodorization module 4 is turned on in conjunction to further improve the air condition in the garbage room 1.

[0038] Air conditioning mode: In summer, in this mode, the exhaust fan 214, the supply fan 215 and the air conditioning module 3 are all turned on. The outdoor fresh air is filtered through the primary filter 212, the heat exchanger 206 and the air conditioning indoor unit 301 in turn and then enters the garbage room 1. The indoor air is exhausted to the outside of the garbage room 1 after passing through the external circulation photocatalyst filter 213 and the heat exchanger 206. The temperature of the fresh air is high before it passes through the heat exchanger 206, and the temperature of the indoor air is low before it passes through the heat exchanger 206. When the fresh air and the indoor air enter the heat exchanger 206 at the same time, heat exchange is performed, which reduces the temperature of the fresh air for the first time, and then the temperature is reduced for the second time after passing through the air conditioning indoor unit 301. The first cooling can recover the air conditioning refrigeration effect and realize energy reuse. At the same time, the internal circulation photocatalyst deodorization device is turned on to improve the air condition in the garbage room 1. It should be noted that the air conditioning mode does not operate in winter.

[0039] Ventilation (heat exchange) + internal circulation deodorization and purification mode: The fresh air and exhaust valves are open, and outdoor air exchanges heat with exhaust air before being delivered indoors, replenishing fresh air and recovering heat. Simultaneously, the internal circulation photocatalytic deodorization device is activated, purifying the indoor air through it and further improving the air quality.

[0040] Internal circulation deodorization and purification mode: the fresh air heat exchange module 2 and the air conditioning module 3 are both closed, and the internal circulation photocatalyst deodorization module 4 is turned on. Only the indoor air is purified. It is suitable for situations where a large amount of fresh air does not need to be introduced.

[0041] In summary, the fresh air of the garbage room intelligent air treatment system is filtered by the primary filter 212 before entering the garbage room 1, so that the fresh air is clean air when entering the garbage room 1, thereby achieving a good ventilation and purification effect. The setting of the fresh air heat exchanger module 2 can realize the heat exchange between the fresh air and the air in the garbage room 1. For example, when the air conditioner is turned on to cool down the garbage room 1 and the fresh air heat exchanger module 2 draws the internal cold air out, the drawn cold air passes through the heat exchanger 206 to lower the temperature of the fresh air, which can reduce the loss of air conditioning cooling effect and reduce the air conditioning cooling power, thereby achieving the effect of improving energy utilization efficiency. The intelligent control system automatically adjusts the system operation mode and parameters by collecting parameters such as temperature and air quality in real time. , achieving precise environmental control, reducing manual intervention, and improving management efficiency. Remote monitoring and control of the system are achieved through the Internet of Things technology. Managers can view the system operation status and the air quality in the garbage room 1 anytime and anywhere, and make timely adjustments and management. The internal circulation photocatalyst deodorization module 4 circulates and deodorizes in the closed garbage room 1, which can greatly reduce the odor in the garbage room 1. When the air deodorized by the internal circulation photocatalyst deodorization module 4 is discharged, it is also filtered and deodorized again through the external circulation photocatalyst filter 213 inside the fresh air heat exchanger module 2. Since the external circulation photocatalyst filter 213 performs secondary filtration, the maximum processing load is low, so that the number of photocatalytic active sites is sufficient, which can significantly improve the air quality.
