Description

Technical Field

[0001] The present invention relates to the technical field of material processing, and in particular to a material processing device and method combining a heat pump with ozone. Background Art

[0002] Material processing refers to the process of adjusting the environmental factors of the materials, such as temperature, humidity, proportion of air components, electromagnetic wave irradiation, etc., through certain process requirements, and then regulating the moisture content, chemical composition, bacteria carrying conditions, etc. of the materials. A heat pump is an efficient and energy-saving device that makes full use of low-grade thermal energy. It has a heat-absorbing end and a heat-releasing end, and can use input energy to transfer heat from the low-temperature side to the high-temperature side. Therefore, it can be used to adjust environmental factors and has been applied in the drying and preservation of grains and agricultural products. Ozone is an allotrope of oxygen that can be artificially generated by an ozone generator. It has strong oxidizing properties and has killing and inhibitory effects on microorganisms such as bacteria, viruses, and fungi. It has been applied in the sterilization of vegetables and fruits.

[0003] Usually, the material processing device using heat pump technology (hereinafter referred to as "heat pump device") and the material processing device using ozone technology (hereinafter referred to as "ozone device") are independent of each other. When a batch of materials are processed in one place, there are usually problems such as large space occupied by the device, high investment cost, low degree of process automation, and high labor intensity of material transportation. However, it is difficult to use the two together because they have an adverse effect on each other. For example, the heat pump device produces a warming effect on the environment in which the materials are located; and the core equipment in the ozone device is the ozone generator. In a high temperature environment, the ozone generator will have problems such as decreased ozone yield, increased power consumption, decreased reliability, and decreased life.

[0004] It can be seen that in the same application environment, the independent use of the heat pump device and the ozone device will cause problems of design redundancy and insufficient integration, while simply combining the two will produce the opposite effect, which is likely to lead to the opposite effect of reduced material handling efficiency, reduced system reliability, and reduced life.

[0053] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0054] like Figures 1 to 5As shown, the present invention provides a material processing device combining a heat pump and ozone (which may be referred to as "material processing device" in the embodiment of the present invention), and based on the material processing device, further proposes a material processing method combining a heat pump and ozone (which may be referred to as "material processing method" in the embodiment of the present invention).

[0055] like Figure 1 As shown, the material processing device includes a processing system, an ozone system, a heat pump system and a control mechanism. Among them, the processing system includes a processing chamber 9 for placing materials 10. The ozone system is connected to the processing chamber 9 and is used to release ozone into the processing chamber 9 in the startup state. The heat pump system is connected to the processing chamber 9, and the heat pump system is used to input cold into the processing chamber 9 before the ozone system releases ozone into the processing chamber 9 by changing its own working state, and input heat into the processing chamber 9 after the ozone system releases ozone into the processing chamber 9. The control mechanism includes at least two control chambers, a pair of heat exchangers are respectively located in two of the control chambers, and each control chamber is used to change the working state of each heat exchanger by changing the on-off state between each other and the on-off state between each control chamber and the processing chamber. The control mechanism is connected to the heat pump system, and the control mechanism is used to change the working state of the heat pump system. The material processing device can selectively release cold or heat in the processing system according to the progress of the material 10 processing without moving the material 10, and only utilize the change of the working state of the same heat pump system itself, so as to provide a cold environment for the ozone system in the processing system in advance, so that the heat pump system and the ozone system can cooperate with each other, and the adverse effect of the heat pump system on the ozone system can be converted into an overall organic combination between the two, thereby improving the material 10 processing efficiency, shortening the material 10 processing time, improving the device reliability, and increasing the device life. Compared with the prior art, the material processing device can also reduce the device volume, manufacturing cost, and use of manpower, and also has a more automated operation process and more efficient system performance.

[0056] It is understandable that in the material processing device, the processing chamber 9 is preferably a closed space, in which the material 10 can be placed. In order to facilitate the adjustment of the humidity inside the processing chamber 9 and the balance of the air pressure inside the processing chamber 9, it is preferred to construct at least one external air door on the wall of the processing chamber 9, and the connection between the processing chamber 9 and the external environment is achieved by opening the external air door, and the closed space is constructed in the processing chamber 9 by closing the external air door. Figure 2 A first process chamber damper 91 and a second process chamber damper 92 are shown.

[0057] It should be noted that if the fan of the heat pump system or the ozone system can drive the air circulation in the treatment chamber 9 when started, then an internal fan may not be installed in the treatment chamber 9; otherwise, an internal fan that can ensure air circulation needs to be installed in the treatment chamber 9.

[0058] In one embodiment, Figure 2 As shown, the heat pump system includes a pair of heat exchangers, a compressor 1 and a throttling device 4. The compressor 1 and the throttling device 4 are respectively connected in series between the pair of heat exchangers. Preferably, the compressor 1 is connected between the first ends of the pair of heat exchangers, and the throttling device 4 is connected in series between the second ends of the pair of heat exchangers. In the series circuit composed of the compressor 1, the pair of heat exchangers and the throttling device 4, the throttling device 4 is used to control the flow rate of the heat exchange medium flowing through the series circuit and the opening and closing of the pipeline.

[0059] In the above-mentioned heat pump system, at least one of the pair of heat exchangers is used to input cold or heat into the processing chamber 9. It should be noted that the heat pump system inputs heat into the processing chamber 9 as the first state of the heat pump system, and the heat pump system inputs cold into the processing chamber 9 as the second state of the heat pump system. The change of the working state of the above-mentioned heat pump system itself specifically refers to: the heat pump system switches between the first state and the second state. Further, preferably, the pair of heat exchangers includes a first heat exchanger 21 and a second heat exchanger 22, then the change of the working state of the above-mentioned heat pump system itself further refers to: there is always one heat exchanger in the pair of heat exchangers that can change its own working state to achieve switching between inputting cold and inputting heat into the processing chamber 9, for example Figure 2 The first heat exchanger 21 and the second heat exchanger 22 are shown; or, in a pair of heat exchangers, one heat exchanger can input heat into the processing chamber 9, and the other heat exchanger can input cold into the processing chamber 9, and the switching between inputting cold and inputting heat into the processing chamber 9 is achieved by switching the connection state between the pair of heat exchangers and the processing chamber 9, for example Figures 3 to 5 A first heat exchanger 21 and a second heat exchanger 22 are shown.

[0060] It is understandable that in order to accelerate the heat exchange efficiency of the heat exchanger, it is preferred to provide a fan on one side of each heat exchanger, for example Figures 2 to 5 The first fan 31 is installed on one side of the first heat exchanger 21 , and the second fan 32 is installed on one side of the second heat exchanger 22 .

[0061] In one embodiment, Figure 2 As shown, the control mechanism includes a reversing valve 5, which is connected in series in the above-mentioned series circuit and is used to change the flow direction of the heat exchange medium in the series circuit, thereby realizing reliable switching of the working state of the heat exchanger itself in the heat pump system. Figure 2As shown, the reversing valve 5 includes a valve body and a first port, a second port, a third port and a fourth port arranged on the valve body. The first heat exchanger 21 is located outside the processing chamber 9, and the second heat exchanger 22 is located inside the processing chamber 9. The second heat exchanger 22 is used to input cold or heat into the processing chamber 9 by changing its own working state. Among them, the first heat exchanger 21 is bidirectionally connected to the first port, the second heat exchanger 22 is bidirectionally connected to the third port, and the input end and the output end of the compressor 1 are respectively connected to the second port and the fourth port. Preferably, a plurality of first one-way flow paths and a plurality of second one-way flow paths are arranged in the valve body, and the first port and the second port, and the fourth port and the third port are respectively connected with the first one-way flow paths, and the fourth port and the first port, and the third port and the second port are connected with the second one-way flow paths. The reversing valve 5 is used to change the flow direction of the working medium in the valve body by switching the opening and closing of the above-mentioned ports, thereby changing the working state of the second heat exchanger 22, that is, to achieve the switching of the second heat exchanger 22 between inputting cold or inputting heat into the processing chamber 9.

[0062] It should be noted that the material processing device also includes a heat storage system, which is connected to the heat pump system. The heat storage system is used to store heat on the heat release side of the heat pump system during the process of the heat pump system inputting cold energy into the processing chamber 9, and to transfer the stored heat to the heat pump system during the process of the heat pump system inputting heat into the processing chamber 9.

[0063] like Figure 6 As shown, the heat storage system may include a first heat storage mechanism 131. The first heat storage mechanism 131 is a cavity structure mounted on the outside of the first heat exchanger 21 and the corresponding fan. The first heat storage mechanism 131 is used to perform heat exchange with the first heat exchanger 21 based on the opening and closing switching state of each port of the reversing valve 5.

[0064] Furthermore, the first heat storage mechanism 131 is constructed as a cavity structure, and preferably the first heat storage mechanism 131 of the cavity structure is constructed as a container or structure containing heat storage material to facilitate heat exchange. Figure 6The installation position shown is installed in the first heat storage mechanism 131 of the cavity structure, so as to facilitate heat exchange between the first heat storage mechanism 131 and the first heat exchanger 21. When the reversing valve 5 sets the first heat exchanger 21 as a condenser through the port switching operation, the heat of the first heat exchanger 21 is taken out and released to the outside through the airflow delivered by the first fan 31, and part of the heat will be absorbed by the first heat storage mechanism 131, so that the temperature of the heat storage material inside the first heat storage mechanism 131 rises, that is, this part of the energy is accumulated in the first heat storage mechanism 131; when the reversing valve 5 changes the first heat exchanger 21 into an evaporator through the port switching operation, the first heat exchanger 21 absorbs heat from the outside, and the heat accumulated in the first heat storage mechanism 131 can be brought to the first heat exchanger 21 through the airflow delivered by the first fan 31. This structural setting can accelerate the efficiency of heat exchange between the first heat exchanger 21 and the outside, thereby further improving the overall heat exchange efficiency and heat exchange amount of the device.

[0065] In one embodiment, Figure 3 As shown, the control mechanism is a group of control chambers. The control chamber includes a first space 111, a transition space 112, and a second space 113 connected in sequence. The first space 111, the transition space 112, and the second space 113 are all connected to the processing chamber 9. The first heat exchanger 21 is located in the first space 111, and the second heat exchanger 22 is located in the second space 113.

[0066] When the second space 113 is connected to the processing chamber 9, the transition space 112 is connected to the second space 113 and the processing chamber 9 respectively, so that the airflow flows in sequence among the processing chamber 9, the second space 113, the transition space 112 and the processing chamber 9 to form an airflow cycle. Figure 4 In this state, before the ozone system is started and releases ozone into the treatment chamber 9, and / or during the process of the ozone system releasing ozone into the treatment chamber 9, the second heat exchanger 22 inputs cold energy into the treatment chamber 9.

[0067] When the first space 111 is connected to the processing chamber 9, the second space 113 is connected to the first space 111 and the processing chamber 9 respectively, so that the airflow flows in sequence among the processing chamber 9, the transition space 112, the first space 111 and the processing chamber 9 to form an airflow cycle. Figure 5 In this state, the ozone system is closed, and the first heat exchanger 21 inputs heat into the processing chamber 9.

[0068] It can be seen that in this embodiment, by switching the connection state between different spaces and the processing chamber 9, it is possible to switch the connection state between a pair of heat exchangers and the processing chamber 9, thereby changing the working state of the heat pump system itself.

[0069] In order to realize the fast and reliable switching of the connection state between a pair of heat exchangers and the processing chamber 9, it is preferred that an openable and closable inner air door is provided between the transition space 112 and the first space 111 and the second space 113, and an openable and closable inner air door is provided between the first space 111, the transition space 112, the second space 113 and the processing chamber 9. In order to realize the internal air pressure regulation of the first space 111, the transition space 112, the second space 113 and the processing chamber 9, and the regular ventilation with the external environment, it is preferred that the first space 111, the transition space 112, the second space 113 and the processing chamber 9 are respectively provided with at least one openable and closable outer air door, which can be connected to the external environment when opened.

[0070] like Figures 3 to 5 As shown, the outer damper includes a first damper 901, a second damper 902, a third damper 903, a fourth damper 904, a seventh damper 907 and an eleventh damper 911. The inner damper includes a fifth damper 905, a sixth damper 906, an eighth damper 908, a ninth damper 909 and a tenth damper 910. Among them, the first damper 901 and the fourth damper 904 are respectively arranged on the side wall adjacent to the external environment of the first space 111. The second damper 902 is arranged on the side wall adjacent to the transition space 112 and the external environment. The third damper 903 and the seventh damper 907 are arranged on the side wall adjacent to the second space 113 and the external environment. The eleventh damper 911 is arranged on the side wall adjacent to the processing chamber 9 and the external environment. The fifth damper 905 is arranged on the wall adjacent to the first space 111 and the transition space 112. The sixth damper 906 is arranged on the wall adjacent to the transition space 112 and the second space 113. The eighth damper 908 is disposed on the wall surface adjacent to the first space 111 and the processing chamber 9. The ninth damper 909 is disposed on the wall surface adjacent to the transition space 112 and the processing chamber 9. The tenth damper 910 is disposed on the wall surface adjacent to the second space 113 and the processing chamber 9. The specific relationship between the opening and closing states of the above-mentioned dampers and the working state of the heat pump system is described in detail in the following material processing method, and will not be repeated here.

[0071] It should be noted that if Figure 7As shown, the heat storage system may further include a second heat storage mechanism 132 and a heat storage chamber 12. The heat storage chamber 12 includes a heat storage space, a first heat transfer space and a second heat transfer space. The second heat storage mechanism 132 is installed in the heat storage space. The first heat transfer space is surrounded by all external air doors of the first space 111, such as the first air door 901 and the second air door 902 mentioned above, so that the first heat transfer space and the first space 111 can be connected by opening at least one of the first air door 901 and the second air door 902, so that the circulation of air flow can drive the exchange of cold or heat between the first heat transfer space and the first space 111. The second heat transfer space is surrounded by all external air doors of the second space 113, such as the third air door 903 and the seventh air door 907 mentioned above, so that the first heat transfer space and the second space 113 can be connected by opening at least one of the third air door 903 and the seventh air door 907, so that the circulation of air flow can drive the exchange of cold or heat between the first heat transfer space and the second space 113.

[0072] In order to facilitate the airflow interruption between the first heat transfer space and the second heat transfer space and the external environment, the first heat transfer space and the second heat transfer space are preferably provided with at least one openable and closable external air door, that is, Figure 7 As shown, the first heat transfer space is provided with a first heat storage air door 121 that can be opened and closed, and the second heat transfer space is provided with a second heat storage air door 122 that can be opened and closed.

[0073] In order to facilitate the airflow disconnection between the first heat transfer space and the second heat transfer space and the heat storage space, so that the heat storage space can be connected with the first heat transfer space and / or the second heat transfer space, so that the second heat storage mechanism 132 can exchange heat with the airflow of the first heat transfer space and / or the second heat transfer space by airflow, and then indirectly exchange heat with the airflow of the first space 111 and the second space 113, it is preferred that the first heat transfer space and the second heat transfer space are respectively connected to the heat storage space through an openable and closable intermediate air door. Preferably, as Figure 7 As shown, the intermediate air door includes a first intermediate air door 123 and a second intermediate air door 124, wherein the first intermediate air door 123 is arranged between the first heat transfer space and the heat storage space, and the second intermediate air door 124 is arranged between the second heat transfer space and the heat storage space.

[0074] Specific as Figure 7As shown, a surrounding structure is constructed outside the first space 111 provided with the first damper 901 and the fourth damper 904 as the first heat transfer space, and a surrounding structure is constructed outside the second space 113 provided with the third damper 903 and the seventh damper 907 as the second heat transfer space. The heat storage space is connected between the first heat transfer space and the second heat transfer space and is located outside the transition space, but the heat storage space is not connected to the transition space 112, that is, the transition space 112 can still be connected to the external environment when the second damper 902 is opened. The second heat storage mechanism 132 installed in the heat storage space is constructed as a container or structure containing heat storage materials for convenient heat exchange.

[0075] In such Figure 4 The processing chamber 9 of the material processing device shown is in the process of heating up, the second intermediate air door 124 and the second heat storage air door 122 are placed in a closed state, the first intermediate air door 123 is placed in an open state, and the first heat storage air door 121 is initially closed. When the temperature of the second heat storage mechanism 132 rises to the heat storage set value, the first heat storage air door 121 is opened, so that the heat is discharged into the first heat transfer space through the first air door 901 and / or the fourth air door 904, and part of the heat is absorbed by the second heat storage mechanism 132; in the above process, when the second heat storage mechanism 132 stores enough energy, the excess energy is released to the external environment.

[0076] In such Figure 5 The processing chamber 9 of the material processing device shown is in the process of cooling down, the first intermediate air door 122 and the first heat storage air door 121 are placed in a closed state, the second intermediate air door 124 is placed in an open state, and the second heat storage air door 123 is initially closed. When the temperature of the second heat storage mechanism 132 is reduced to the heat release setting value, the second heat storage air door 124 is opened, so that heat enters the second space 113 through the third air door 903 and / or the seventh air door 907; in the above process, when the temperature of the second heat storage mechanism 132 is completely released, the heat pump system absorbs heat from the external environment.

[0077] It is understandable that the above-mentioned heat storage material can be water, paraffin or heat storage bricks.

[0078] It is understandable that the above-mentioned container or structure containing heat storage material means: the "container" is mainly used to hold liquid heat storage material (such as water) or phase change heat storage material (such as paraffin). The container is suitable for using a shell and tube heat exchanger or a fin tube heat exchanger to facilitate heat exchange. The "structure" is for solid heat storage material (such as heat storage brick). Solid heat storage material can use its own shape, such as convex and concave grooves on the heat storage brick, to form a structure that is convenient for heat exchange.

[0079] In one embodiment, the ozone system includes an ozone generator 6 and an ozone damper, and the ozone damper is openably connected between the ozone generator 6 and the treatment chamber 9. Preferably, the ozone system also includes an ozone blower 8, which is arranged on one side of the ozone generator 6. The ozone blower 8 is used to drive the airflow in the ozone space of the ozone system, so that the airflow can fully flow through the ozone generator 6, and the ozone can be sent into the treatment chamber 9 through the airflow.

[0080] It should be noted that if the heat pump system or the airflow in the treatment chamber 9 can allow the airflow in the treatment chamber 9 to fully flow through the ozone system, the ozone blower 8 may not be provided in the ozone system.

[0081] For example Figure 2 In the ozone system shown, the ozone space is a channel structure with both ends connected to one side of the treatment chamber 9, and the ozone generator 6 and the ozone blower 8 are arranged in the channel structure. The above-mentioned ozone damper includes a first ozone damper 71 and a second ozone damper 72, and the first ozone damper 71 and the second ozone damper 72 are respectively opened and closed and arranged at both ends of the channel structure.

[0082] For example Figure 3 In the ozone system shown, the ozone space is a closed space connected to one side of the treatment chamber 9, and the ozone generator 6 and the ozone blower 8 are arranged in the closed space. The above-mentioned ozone damper is an ozone main damper 73 that can be opened and closed and is arranged between the closed space and the treatment chamber 9. The ozone main damper 73 is preferably a damper.

[0083] It is understandable that the ozone production rate of the ozone generator 6 is related to the treatment system, and the steady-state ozone concentration (i.e., volume fraction) in the treatment chamber 9 of the treatment system should be at least greater than 0.5 ppm. The airflow delivered by the ozone blower 8 flows through the ozone generator 6. The ozone damper includes an actuator for performing its switching action.

[0084] It can be understood that the specific relationship between the start and stop of the ozone system and the working state of the heat pump system is described in detail in the following material processing method and will not be repeated here.

[0085] In one embodiment, the material processing device further comprises an electronic control system, such as Figure 1As shown, the electric control system is connected to the heat pump system, the treatment system and the ozone system through electrical control. Specifically, the electric control system includes a human-machine interaction component, a sensor component and a controller. The human-machine interaction component includes a body and a touch screen, a button and an indicator light respectively arranged on the body. The human-machine interaction component can display various output parameters of the material processing process to the operator, enable the participant to input various parameters, and can also prompt and warn the material processing process through the indicator light. The sensor component includes a temperature sensor, a humidity sensor and an ozone content sensor respectively connected to the human-machine interaction component. The temperature sensor, the humidity sensor and the ozone content sensor are respectively installed in the treatment chamber 9, so as to provide the controller with environmental parameters in the treatment chamber 9, such as real-time temperature, real-time humidity and real-time ozone concentration. The controller is respectively connected to the sensor component and the human-machine interaction component, and is used to advance the material processing process according to the environmental parameters in the treatment chamber 9, and reliably monitor the material 10 in the treatment process. The controller can also preset the temperature range and the ozone concentration range, so as to ensure that the reliability of the material 10 processing process is higher and the degree of automation is higher.

[0086] It is understandable that the sensor assembly also includes conventionally set electrical parameter instruments. The controller includes but is not limited to a programmable logic controller, a single chip microcomputer and a control instrument. The above-mentioned electric control system also includes an actuator. The actuator includes but is not limited to a circuit breaker, a contactor, a thermal relay and an intermediate relay.

[0087] The material processing method described in the embodiment of the present invention is performed by the above-mentioned material processing device. In the method, the material 10 is placed in the processing chamber 9 and remains stationary. First, the heat pump system is used to continuously input cold into the processing chamber 9, so as to provide a cold environment in advance for the ozone system in the processing chamber 9; then the ozone system is used to continuously release ozone in the processing chamber 9 to achieve the required ozone concentration range during the material processing process; finally, the above-mentioned heat pump system is switched to continuously input heat into the processing chamber 9, so as to increase the temperature of the environment in the processing chamber 9. In the process described in the present method, the material 10 does not need to be moved in the processing chamber 9, that is, for the same batch of materials 10 in the same processing system, the same set of heat pump system changes its own working state to selectively release cold or heat in the processing system according to the progress of the material 10 processing, so as to provide a cold environment in advance for the ozone system in the processing system, so that the heat pump system and the ozone system cooperate with each other, and the adverse effects of the heat pump system on the ozone system are transformed into an organic combination of the two as a whole, thereby improving the processing efficiency of the material 10, shortening the processing time of the material 10, improving the reliability of the device, and improving the service life of the device.

[0088] Furthermore, the material processing method described in the present invention is performed by the above-mentioned heat pump and ozone combined material processing device, so that the material processing method has all the advantages of the above-mentioned material processing device, which will not be repeated here.

[0089] Specifically, the material processing method comprises the following steps:

[0090] Step 1: placing the material 10 in the processing chamber 9 of the processing system, and setting the processing chamber 9 as a closed space;

[0091] Step 2: driving the heat pump system to continuously input cold energy into the processing chamber 9, so that the temperature in the processing chamber 9 is reduced and maintained within the first temperature range;

[0092] Step 3: driving the ozone system to continuously release ozone into the treatment chamber 9, so that the ozone concentration in the treatment chamber 9 increases and is maintained within a concentration range, so that the treatment chamber 9 is in a first environmental state;

[0093] Step 4: After the processing chamber 9 is in the first environmental state for a period of time, the ozone system is turned off, and the heat pump system is driven to continuously input heat into the processing chamber 9, so that the temperature in the processing chamber 9 is increased and maintained within the second temperature range until the material 10 is processed.

[0094] Figure 2 In the material processing device shown, a reversing valve 5 is used to switch the functions of the two heat exchangers, that is, when the heat exchange valve is in different conduction states, the same heat exchanger can be an evaporator or a condenser, and the other heat exchanger is the opposite. Based on this structure, the specific implementation process of the material processing method described in the embodiment of the present invention is as follows:

[0095] (1) Place the material 10 in the processing chamber 9 of the processing system, close the feed port of the processing chamber 9 and close the first processing chamber damper 91 and the second processing chamber damper 92 to isolate the processing chamber 9 of the processing system from the outside world and form a closed space.

[0096] (2) Afterwards, the heat pump system works, that is, the compressor 1, the first fan 31 and the second fan 32 are running, and the reversing valve 5 is in a conducting state so that the heat pump system inputs cold energy to the processing system; the heat pump system inputs cold energy into the processing chamber 9 through the second heat exchanger 22, so that the temperature in the processing chamber 9 is reduced, and the real-time temperature is fed back through the temperature sensor in the processing chamber 9 to control the start and stop of the compressor 1, so that the temperature in the processing chamber 9 reaches and is maintained within the first temperature range. The first temperature range is preferably 2°C to 5°C or any smaller range within the temperature range.

[0097] (3) When the above-mentioned "temperature in the treatment chamber 9 reaches and is maintained within the first temperature range", the ozone system works, that is, the first ozone damper 71 and the second ozone damper 72 are opened, and the ozone blower 8 and the ozone generator 6 are operated, thereby releasing ozone into the treatment chamber 9, increasing the ozone concentration in the treatment chamber 9, and feeding back the real-time ozone concentration through the ozone content sensor in the treatment chamber 9 to control the start and stop of the ozone generator 6, thereby increasing the ozone concentration in the treatment chamber 9 and maintaining it within the preset ozone concentration range, so that the internal environment of the treatment chamber 9 is in the first environment state. The ozone concentration range is preferably 0.1ppm to 8ppm or any smaller range within the ozone concentration range.

[0098] (4) Maintaining the above working state for a certain period of time, that is, maintaining the first environmental state in the processing chamber 9 within a first time range. The first time range is preferably 1 hour to 10 hours or any smaller range within the time range.

[0099] (5) After the first time range ends, the ozone system stops working, that is, the first ozone damper 71 and the second ozone damper 72 are completely closed, and the ozone fan 8 and the ozone generator 6 stop working; but the heat pump system continues to work. In this state, the reversing valve 5 is switched to the conduction state so that the heat pump system inputs heat to the treatment system, and the second heat exchanger 22 inputs heat into the treatment chamber 9 to increase the temperature in the treatment chamber 9, and the real-time temperature is fed back by the temperature sensor in the treatment chamber 9 to control the start and stop of the compressor 1, so that the temperature in the treatment chamber 9 reaches and is maintained within the second temperature range. The first temperature range is preferably 35°C to 85°C or any smaller range within the temperature range; and by adjusting the first treatment chamber damper 91 and the second treatment chamber damper 92 of the treatment system, the humidity in the treatment chamber 9 is maintained within a preset humidity range. The humidity range is preferably 20% to 99% or any smaller range within the temperature range. Then the treatment chamber 9 is in the second environmental state.

[0100] (6) Maintaining the above working state for a certain period of time, that is, maintaining the second environmental state in the processing chamber 9 within a second time range. The second time range is preferably 0 to 30 days or any smaller range within the time range.

[0101] (7) After the second time range ends, the heat pump system stops working, the processing system stops working, and the material 10 in the processing chamber 9 is taken out, and the material processing process is completed.

[0102] Figures 3 to 5In the material processing device shown, the control room structure is used to separate the first heat exchanger 21 and the second heat exchanger 22 of the heat pump system by using a plurality of closed spaces that can be opened and closed, and an inner air door and an outer air door are set in each closed space, so that the processing chamber 9 can be connected to different heat exchangers of the heat pump system by using the combined action of opening and closing the inner air door and the outer air door, thereby realizing the change of the working state of the heat pump system itself. Based on this structure, the specific implementation process of the material processing method described in the embodiment of the present invention is as follows:

[0103] (1) Figure 4 As shown, the material 10 is placed in the processing chamber 9 of the processing system, the feed port of the processing chamber 9 is closed, and the second air door 902, the third air door 903, the fifth air door 905, the seventh air door 907, the eighth air door 908 and the eleventh air door 911 are closed, and the ninth air door 909 and the tenth air door 910 are opened to connect the processing chamber 9 with the second space 113 where the second heat exchanger 22 is located and isolate it from the external environment, and use the transition space 112 as an air flow transition channel to avoid the intersection of the reciprocating air flows and the formation of vortices during the air flow circulation, thereby constructing a closed space connected between the second heat exchanger 22 and the processing chamber 9.

[0104] (2) Afterwards, the heat pump system works, that is, the compressor 1, the first fan 31 and the second fan 32 are running, the first damper 901 and the fourth damper 904 are opened, the first heat exchanger 21 exchanges heat with the external environment, and the second heat exchanger 22 inputs cold energy into the processing chamber 9, as shown in FIG. Figure 4 As shown by the arrow, the temperature in the processing chamber 9 is lowered, and the real-time temperature is fed back by the temperature sensor in the processing chamber 9 to control the start and stop of the compressor 1, so that the temperature in the processing chamber 9 reaches and is maintained within the first temperature range. The first temperature range is preferably 2°C to 5°C or any smaller range within the temperature range.

[0105] (3) When the temperature in the treatment chamber 9 reaches and is maintained within the first temperature range, Figure 4 As shown, the ozone system works, that is, the ozone main damper 73 is opened, the ozone fan 8 and the ozone generator 6 are running, thereby releasing ozone into the treatment chamber 9, increasing the ozone concentration in the treatment chamber 9, and feeding back the real-time ozone concentration through the ozone content sensor in the treatment chamber 9 to control the start and stop of the ozone generator 6, thereby increasing the ozone concentration in the treatment chamber 9 and maintaining it within a preset ozone concentration range, so that the internal environment of the treatment chamber 9 is in a first environment state. The ozone concentration range is preferably 0.1ppm to 8ppm or any smaller range within the ozone concentration range.

[0106] (4) Maintaining the above working state for a certain period of time, that is, maintaining the first environmental state in the processing chamber 9 within a first time range. The first time range is preferably 1 hour to 10 hours or any smaller range within the time range.

[0107] (5) After the first time period ends, if Figure 5 As shown, the ozone system stops working, that is, the ozone main damper 73 is completely closed, the ozone fan 8 and the ozone generator 6 stop working; but the heat pump system continues to work, that is, the compressor 1, the first fan 31 and the second fan 32 continue to run. However, the status of each damper in the control room has changed, such as Figure 5 As shown, specifically: the first damper 901, the fourth damper 904, the sixth damper 906 and the tenth damper 910 are closed, and the second damper 902, the third damper 903, the fifth damper 905, the seventh damper 907, the eighth damper 908, the ninth damper 909 and the eleventh damper 911 are opened, so that the first heat exchanger 21 inputs heat into the processing chamber 9, as shown in FIG. Figure 5 As shown by the arrow, the second heat exchanger 22 exchanges heat with the external environment; and the opening of the eleventh damper 911 allows the hot air to quickly enter the processing chamber 9 due to the temperature difference between the inside and outside and the pressure difference, thereby accelerating the temperature increase in the processing chamber 9, and the real-time temperature is fed back by the temperature sensor in the processing chamber 9 to control the start and stop of the compressor 1, so that the temperature in the processing chamber 9 reaches and is maintained within the second temperature range. The first temperature range is preferably 35°C to 85°C or any smaller range within the temperature range; and by adjusting the second damper 902 and the eleventh damper 911 of the processing system, the humidity in the processing chamber 9 is maintained within a preset humidity range. The humidity range is preferably 20% to 99% or any smaller range within the temperature range. Then the processing chamber 9 is in the second environmental state.

[0108] (6) Maintaining the above working state for a certain period of time, that is, maintaining the second environmental state in the processing chamber 9 within a second time range. The second time range is preferably 0 to 30 days or any smaller range within the time range.

[0109] (7) After the second time range ends, the heat pump system stops working, the processing system stops working, and the material 10 in the processing chamber 9 is taken out, and the material processing process is completed.
