Example: As shown in Figure 15, the wood drying process of the present invention.

After the process starts:

First, the drying chamber 3 is installed.

The first step is to install the connection components. The fixing base 33 of the coupling device 2 is attached to the inside of the cabin 1 by the hull fixing bolts 33 . As shown in Figure 1.

The second step is to install the bracket structure. Put the bracket rod 48 of the bracket 43 into the inner side of the bracket cavity 35, one end of the bracket rod 43 abuts the groove 40 on the fixed seat 31, and the other end of the bracket rod 48 abuts the fixed cushion block 39, rotate the handle 36, the handle 36 Drive the fixed pad 39 to move through the threaded rod 37, fix the support rod 48 on the fixed seat 31, and connect the support rod 48 through the connecting piece 49.

The structure of the capsule 42 when unfolded is a cuboid structure, and the cabin 1 is a cuboid structure. The structure of the support 43 is matched with the structure of the capsule 42 when the capsule 42 is unfolded, so that the space of the cabin 1 can be fully utilized. As shown in Figure 3.

The fourth step is to install the upper cover 44 . After the capsule 42 is installed, the related equipment is connected, the wood to be dried is put in, and the upper cover 44 of the drying chamber is installed, so that the capsule 42 is in a closed environment. As shown in Figure 4.

Then, heat. As shown in Figure 5.

The first step is heat collection and heat exchange. The boiler 6 works normally, and a large amount of waste heat is generated during the period. The waste heat collector 11 collects the heat and transfers the heat through the heat medium. The water pump 13 sends the heat medium to the evaporator 18 through the hot water pipe 12 to create a high temperature environment and make the evaporator In 18, the cooling liquid evaporates and absorbs heat, which realizes the transfer of heat in different media, and the cooled heat medium returns to the waste heat collector 11 through the cold water pipe 14 to realize the heat medium circulation of the waste heat collection process. The solar water heater 7 is connected to the hot water pipe 12 through the solar hot water pipe 15, the water outlet of the evaporator 18 is connected to the solar water inlet pipe 16, and the solar water heater 7 can provide some heat to the evaporator.

The second step is to heat the hot air for heating. The evaporated high-temperature refrigerant liquid vapor is transported to the condenser 24 by the compressor one 21 through the refrigerant liquid vaporization pipe 20. When the compressor one 21 compresses the refrigerant liquid vapor, the temperature rises due to the compression of the gas, and the temperature of the compressed and conveyed refrigerant liquid vapor increases. High, the fan 26 introduces the outside air at room temperature through the fresh air duct 25 to cool the high-temperature refrigerant liquid vapor in the condenser 24, the high-temperature refrigerant liquid vapor cools and liquefies and releases heat to form hot air, and the liquefied refrigerant returns through the refrigerant liquid return pipe 19. In the evaporator 18, the circulation of the refrigerant liquid medium in the air heating process is realized. The boiler high-temperature steam generated during the operation of the boiler 6 is connected to the evaporator 13 through the boiler steam pipe 63, and the heat therein is recovered and utilized.

The third step is drying and heating. The generated hot air is transported to the drying chamber 3 by the second compressor 28 through the warm air pipe 27 to realize the transfer of heat, and with the continuous operation of the boiler 6, it continues to supply heat for the drying chamber 3, and the warm air pipe 27 continues to supply heat to the drying chamber 3. An air valve 1 29 is provided to control the delivery of hot air, a temperature controller 67 is provided on the cabin 1, and a sensor 69 is provided inside the drying chamber 3 to monitor the temperature of the delivered air. .

Then, stabilize the voltage. The drying chamber 3 is a closed space, and the space is filled with wet wood. The continuous delivery of hot air makes a high temperature and high pressure environment in the drying chamber 3, and the moisture in the wet wood increases in boiling point under the high pressure environment. The humid and hot air in the chamber 3 is transported outward through the return air pipe 62 to keep the air pressure stable. The drying chamber 3 is connected to the evaporator 18 through the return air pipe 62, and the heat in the humid and hot air discharged from the drying chamber 3 is recycled and used for condensation. The moisture is drained through the drain. Among them, the air return pipe 3 is provided with an air valve three 64, which can control the discharge of air.

Then, the extraction of hot and humid air. The continuous delivery of hot air makes the temperature in the drying chamber 3 continue to rise. When the set temperature and air pressure are reached, the heat supply is stopped, the air valve one 29 and the air valve three 64 are closed, and the vacuum pump 59 is used to pump the humid and hot air in the drying chamber 3. Exhaust until it reaches the set low pressure and vacuum environment, the moisture in the wood will reduce the boiling point and vaporize a lot when the air pressure is reduced. Connected to the evaporator 18 where heat is recovered. The water outlet of the capsule 42 is connected to the drain pipe 1 56 through the water valve 55, and part of the hot and humid air is dissipated and condensed through the outer wall of the capsule 42, and the condensed liquid is discharged through the water outlet by the drain pump 54 connected to the drain pipe 1. When the vacuum pump 59 is pumped out , the water valve 55 is closed.

Then, the wood vinegar is collected. As shown in Figure 14.

The first step is natural condensation. The drying chamber 3 is filled with wet wood to be dried, and the heating device 4 continuously heats the drying chamber 3 through the heating pipe 27, so that the wood is dried and distilled into the wood vinegar vapor mixture. Wherein, part of wood vinegar vapor is naturally condensed into wood vinegar on the outer wall of capsule 42 of drying chamber 3, and the water outlet of capsule 42 is connected with drain pipe one 56, and the water pump 54 draws out the naturally condensed wood vinegar, through drain pipe two 57 Discharge into the wood vinegar collection tank 58.

The second part, the voltage regulator collection. The drying chamber 3 is a closed space, and the space is filled with wet wood. The continuous delivery of hot air makes a high temperature and high pressure environment in the drying chamber 3, and the moisture in the wet wood increases in boiling point under the high pressure environment. The humid and hot air in the chamber 3 is transported outward through the return air pipe 62 to keep the air pressure stable. The drying chamber 3 is connected to the evaporator 18 through the return air pipe 62. The evaporator 18 absorbs heat and condenses the wood vinegar vapor through the drain pipe three. 66 is discharged into the wood vinegar collection tank 58.

The third step is to extract and collect. The continuous delivery of hot air makes the temperature in the drying chamber 3 continue to rise. When the set temperature and air pressure are reached, the heat supply is stopped. The hot and humid air is pumped and exhausted until it reaches the set low pressure and vacuum environment. When the air pressure is reduced, the moisture in the wood will have a reduced boiling point and a large amount of vaporization. The humid and hot air is connected to the evaporator 18 through the humid and hot air pipe 65 . The evaporator 18 absorbs heat to condense the wood vinegar vapor and then discharges it into the wood vinegar collection tank 58 through the drain pipe 3 66 .

Then, the sensor monitors. The drying chamber 3 is continuously heated and pumped. The cabin 1 is provided with a moisture content detector 68, and the wet wood in the drying chamber 3 is provided with a sensor 69. During the continuous heating and pumping process, the wet wood is A large amount of moisture evaporates, the moisture content detector 68 monitors the moisture content of the wood through the sensor 69, and detects the weight of the wood through the weighbridge 70. When the set value is reached, it stops working to complete the drying of the wood. At the same time, the system monitors the condition of the waste heat collector 11, monitors the pressure of the vacuum pump 59, monitors the pressure in the capsule 42, monitors the condition of the hot water tank, monitors the moisture content of the wood, monitors the wood weight, monitors the drainage condition, monitors the air temperature and humidity.

Then, the drying chamber 3 is disassembled, the connection state of the support rod 48 is released through the connecting member 49, the capsule 42 is folded, and the foldable capsule bag 45 is folded and compressed. As shown in Figures 9, 10, 11, 12, and 13.
