And 155, and a muffler 156 mounted on the pressure relief main pipe 151 and used to reduce noise generated when the pressure is released.

The pressure control unit 16 has a row of heat main tubes 161, two heat-distributing branch pipes ι 62 and 163 respectively connected to the heat-dissipating pipes 132 and 133 and the heat-dissipating main pipe 161, a heat-generating main pipe 164, and two gas-extracting pipe branches 142 respectively. 143, the heat inlet branch pipes 165, 166 of the heat inlet main pipe 164, and the pressure pipe connecting pipes 167, 168 and the gas output pipe heads 167, 168 and 224, respectively, which are respectively connected to the heat exhaust pipe 162, 163. The valves 171, 172, and two are installed with the regeneration check valves 173 and 174 on the heat inlet pipes 165 and 166, and the pressure build valves 175 and 176 attached to the pressure pipes 167 and 168, respectively. The heating unit 18 has an air filter (8) mounted on the heat receiving main pipe 164, - sending ambient air into the heat main f 164 (four) fan - heating the sent air to a predetermined high temperature heater 183, - control The heat inlet temperature of the heater 183 is turned on - 184, and a heat exhaust temperature switch 185 mounted on the row 'main port 161'. As shown in Figure 2, the conventional heated adsorption dryer! The drying operation method generally includes two operation processes of drying and regenerating, wherein the groove η is in the drying process, and the tank 12 is also regenerated = 1274836, and the second two tanks 11, 12 The process is further switched for repeated use. The following is a brief description of the steps: 1. Drying process: In Figure 1, only the solid line arrow shows the drying process of the tank ,, and the regeneration process of the tank 12 is not in the figure. It is shown that before the drying process, the intake check valve 135, the heat exhaust valve 171, the regeneration check valve 173 and the air outlet check valve 145 are closed, and then the air outlet check valve 144 is opened to make the moisture entering the air intake main pipe 131 The compressed air is introduced into the tank 11 through the intake branch pipe 132, and the moisture is adsorbed through the desiccant, and then the compressed air is sent out from the gas outlet pipe 142 to the gas outlet main unit 141 for use in a process of life: when While the tank 11 performs the drying process, the wet desiccant in the A tank 12 is also regenerated and desorbed, and the regeneration process can be further divided into the pressure, heating, cooling, building pressure and standby. ^ 4 money through large step time 5 minutes, over a heating time required for an ⑽ minutes ~ frit between ⑽ min or more, the pressure build time 5 minutes, standby time: 5 minutes, total regeneration process takes 355 minutes. In Fig. 3 and Fig.*, only the grooves 12 μ i A, the ancient one, the regeneration, and the melon % are shown, and the drying process of the tank 11 is not shown. The solid line arrow in ::3 represents the pressure relief step, since the pressure in the tank 12 172^ } 135 Β 12 is discharged outward through the gas outlet branch 143, the rolling support 153, and the (4) main pipe (5). The heating step is performed as indicated by the dashed arrow in FIG. 3, firstly closing the Maofa 1274836 valve 155 and the regeneration backstop _173, and opening the heat removal target π and the regeneration reverse stop 阙 174' to make the receptacle 12 and the environment conductively open. And starting the air blower a] and the heater (8), the hot air is sent to the tank 12 by the heat receiving main pipe 164, after which the water jet will evaporate into a gaseous state, and then the hot gas is discharged from the heat exhausting branch pipe 163 through the heat exhausting main pipe 16 . As shown by the solid arrow in FIG. 4, the cooling step is performed. First, the regeneration counter valve m' is closed and the pressure building valve 176 is opened, and the dry compressed air is introduced into the outlet gas s 141 m, and the pressure regulating valve 176 is sent to the tank +, thereby The high-temperature dry _ is slowly cooled up and down, and the condensed water is sent to the heat-dissipating branch pipe 163, which is discharged by the heat-dissipating main pipe 161. As shown by the dotted arrow in Fig. 4, the pressure-increasing step is performed, and the heat-dissipating 172 ′ is first closed so that the dry compressed air is accumulated in the tank 12 so that the pressure rises until the pressure of the tank 11 is balanced. As for the standby step, it is about 5 minutes while waiting for the system to release the switching command before switching. 3. Switching process · As shown in Fig. 5, let the two tanks 11 and 12 perform the switching operation of the alternate operation. This process takes about 5 minutes, first closes the opening pressure (7) and opens the intake check valve 135. The humid compressed air is also introduced into the cuvette so that the troughs 11 and 12 simultaneously perform the drying process, and then the closed intake check valve 134' allows the cuvette 12 to carry out the drying process alone, and allows the trough 11 to enter.仃Regeneration process. By alternately switching between the two tanks u and 12, f is used to remove the moisture from the moist compressed air to form a dry air, to continuously supply the downstream end. As can be seen, the above-described heated adsorption dryer 1 can be simultaneously dried and regenerated by two 1274836 tanks 11, 12, and then alternately switched to achieve the purpose of desiccant recycling, but the desiccant must be heated. The dehumidifying agent is dehydrated and cooled to a normal temperature after heating, so that the desiccant can effectively adsorb moisture again. For this reason, the dried dry compressed air must be fed and cooled for 160 minutes. Above, : This will not only cause the dryer 1 to consume more energy, but also cause the whole, #生时间 is too long. 'Because the drying time must be greater than or equal to the regeneration time 、, in order to replace the replacement', so the tanks 11, 12 The volume design must also be relatively large. In particular, the demand for dry compressed air at the factory end is increasing. Μ 'The equipment of the relative dryer is getting bigger and bigger, and the energy source of the household is increasing. Therefore, how will it be regenerated? The energy efficiency is minimized and does not affect the performance of the dryer, which has become an important issue that the industry needs to solve. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a three-dimensional heat adsorption adsorption dryer and a dry regeneration method thereof that can save energy. Therefore, the three-slot heating adsorption dryer of the present invention comprises: three and respectively accommodates a drying agent tank, an air intake unit, an air outlet unit, an early 70, a pressure control unit, and a heating unit. Each tank has an interval of 2, and an outlet. The air intake unit is connected to the inlet of the equal volume tank ▲ and may select to introduce humid compressed air into one of the equal volume tanks. The unit is connected between the outlets of the equal volume tanks, and is dried and dried to separate the tanks. The pressure relief unit is arranged in the exhaust gas discharge tank Φ + ~ Α This is the second rolling pressure. The pressure control unit is connected between the air intake unit and the outlet 1274836 ... and can be used to adjust the pressure. The heating unit dies in the equal volume tank to remove the moisture of the drying material to introduce the humid compressed air into one of the tanks, and when the drying unit is passed through the desiccant unit, the dry compressed air is sent out after drying. = slot - and the other - the tank will pass the (four) single (four) pressure, heating early 70 heating 'and the pressure regulating unit pressure adjustment, etc., in order to remove the desiccant water regeneration" to the re- The slot is waiting for the switch, and let the high temperature

The desiccant can cool naturally. However, the dry regeneration method of the two-slot heating adsorption dryer of the present invention introduces moist compressed air into the beans of the three-reservoir _ 曰 /, τ heart to absorb the water by a desiccant to prepare dry compressed air, and can The desiccant in the tank is heated and regenerated 'including · drying process, - regeneration process' and - standby process. The drying process is to introduce humid compressed air into one of the tanks, so that the drying agent adsorbs the moisture in the air, and then sends the dried compressed air out of the tank. "' The regeneration process has a heating step that provides another of the hot air in the tank and can be used to remove moisture from the moist desiccant. The standby process allows one of the tanks to wait for the switch after the regeneration process, so that the drier can be naturally cooled. After that, the process of switching the equal volume tank is switched, and the humid compressed air is switched into another tank of the standby process, so that another tank performs the drying process, and another tank that completes the regeneration process enters the standby process. As for the completion of the drying process, the recycling process is carried out.

Recycling method, package:: The drying process of the tank heating adsorption dryer is subdivided in order: to be: three special action processes 'there is one of them - the tank is divided and built (four) four steps' when the standby process is carried out, and : Ding Gan, while the process of the process will be carried out in the secondary tank, and in another valley trough 23, after the transfer of the refinement households, the tank 21 will be carried out... although the tanks are drying, the tank After the 22-pass transfer of the tank, the tank 2 is combined with the process. When the tanks are in the process of regeneration, the tank 23 will be dry and flow-in; the process will be cycled in sequence for repeated purposes. The process of the process is briefly described as follows: The main trough trough 21 performs the regeneration flow tank 23 for the regeneration process: #槽22进仃 standby process, see Fig. 6' The line arrows represent the drying process, reverse 阙%, 37, heat removal valve (6), regeneration check 阙 671 : 阙 46, 47, and then open the intake check valve 35 and the exhaust gas back:: Let: wet repeatedly: The contracted air is introduced into the tank by the intake manifold 31 via the intake manifold 32. 2: After the moisture is absorbed, the air is dried again. The rear air is discharged from the air outlet main unit 41. At this time, the tank 22 performs a standby process, and the warm desiccant is naturally cooled. „, the regeneration process after the elevation is attached. After the tank 23 performs the drying flow 13 1274836, the tank 21 is subjected to a regeneration process, the tank 22 is subjected to a drying process, and the tank 23 is flown into the standby process. This re-door has the steps of pressure relief, heating, cleaning and pressure building. When the pressure is released: the heating time of the clock is about 90 minutes, and the time for cleaning and building pressure is about the knife. The total regeneration process (4) is 1G5 minutes, and the dry (four) process and Standby ^ When. In Figs. 8 to 11, the solid-line arrow represents the regeneration flow of the container η, and the dotted line represents the drying process of the container 22, and the 蚯蚓 arrow represents the standby flow of the container 23. As shown in Fig. 8, the (fourth) step of the tank 21 is to first close the inlet check valve 35, the heat exhaust valve 661, the regeneration check valve 671, the gas discharge check 45 and the build press 681, and open. (4) _, let the pressure in the tank 21 be discharged to the outside by the outlet branch pipe 42, the (four) branch pipe 52 and the shallow pressure main pipe 51. As shown in FIG. 9, the heating step performed by the tank 21 is to first close the pressure valve 55 and the regeneration check valves 672, 673, and open the heat exhaust valve 661 and the regeneration check valve 671 'to allow the tank 21 to The environment is turned on, and the blower 72 and the heater 73 are activated. The heat inlet temperature switch 74 controls the temperature of the heater 73. The temperature of the supplied air is raised to about 2 〇 ^ c, and then the heat is applied. The air is sent from the heat-generating main pipe 63 to the tank 21, and the moisture of the desiccant is evaporated into moisture to be discharged outside the heat-dissipating main pipe 61 via the heat-dissipating branch pipe 621. When the heat-dissipating temperature switch 75 detects the discharged water When the gas reaches a temperature of about 65r, the desiccant in the tank 21 has been regenerated, and the control system will order the heater 73 to stop heating, and then the blower 72 stops the air supply. As shown in Fig. 10, it is carried out by the tank 21. In the cleaning step, the regeneration check valves 672 and 673 are closed first, and the pressure build valve 681 is opened, and the dry compressed air 14 1274836 gas is sent into the trough 21, and the residual water vapor heated in the cuvette 21 is discharged to the exhaust heat main pipe 61. As shown in Figure 11, the pressure-building step for the tank 21 is first Thermal valve 661 closes the discharge, so that dry compressed air accumulation in the receiving groove 21, so that the pressure rise until the receiving grooves 22, 23 until the pressure balance on.

3. As shown in Fig. 12, when the tank 21 enters the standby process (see the insects and trees), the tank 22 is also switched to the regeneration process (see the dotted arrow), while the tank 23 is dried. Process (see solid arrow). By alternately switching the containers u^ and 23, the water in the moist compressed air can be adsorbed to be dry compressed air for use. It can be seen from the above description that the present invention has the following advantages (-) which are better than the conventional ones to save the dry dose: under the same performance design conditions, the volume of the per-reservoir 21, 22, 23 of the present invention is about the conventional 5 〇%, so the desiccant design amount of each groove only needs to be 5% of the conventional one. Therefore, according to the total amount of the desiccant, the desiccant design amount of the present invention is 75% of the conventional one, so Save about 25% of the dry dose. (2) Saving device energy: Under the same performance design conditions, since the desiccant design amount of each of the cuvettes 21, 22, 23 of the present invention requires only a conventional 5%% = if the heating time of the two is the same, Therefore, the horsepower of the blower of the present invention and the power of the heater can be reduced by 5〇%, Λ0/π, and the blower and the heater can be made small, so that the space occupied by the invention can also be reduced, and according to the inventor Actual test, ,, 25%. Winter Maoming can also be reduced by 15 1274836 (3) The cooling process can be omitted: the invention uses the three-capacity slots 21, 22, 23 to switch the design' and the standby steps in the regeneration process are separated separately, allowing the standby process to be performed separately. The time is extended to the same time as the drying process, and the cooling process can be omitted, and the heated tanks 21, 22, and 23 are naturally cooled and cooled during the standby process, so that the conventional cooling must be omitted. Energy, so it saves time and energy.

(4) The use efficiency is better: in the case where the height of the cavity is constant, the groove 2, 22, 23 of the present invention is thinner than the conventional groove, so that heat dissipation is relatively easy. Furthermore, since the humid compressed air is introduced into the tank 21 and the UU downward, the desiccant is distributed in a wet and dry layer after being adsorbed by the desiccant, so that the elongated tanks 21, 22, 23 are designed to allow the upper end to be Dryness absorbs more water, and the relative drying and switching time can be extended, so energy can be saved. ...The above § brother can know that the three-slot heating adsorption dryer of the present invention and its dry-can regenerating method are designed to replace the conventional double-tank design with a three-tank design, according to both cyclic control and separation control. The concept of comprehensive control 'utilizes the three-slot cyclic switching method to separate the regeneration process'. The cooling process is omitted and the standby step is performed independently, so the cooling energy can be reduced and the design performance is not (4). The reduction of the desiccant: the reduction of the blower model, the reduction of the heater power, the long adsorption, and the significant reduction in energy consumption, so that the present invention has the effects of reducing energy consumption and the like, and indeed can achieve the invention (4). Therefore, i Ming is not only unprecedented, but also available for industrial use. 2, the above is only the (4) (4) of the present invention, and the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are not limited to the invention. It is still within the scope of the invention patent.

The drying process includes: drying the humid air into one of the tank desiccants to absorb the moisture in the air, and then drying the ^ Send out the tank, % teach the cattle regeneration process: with a further addition of hot air to provide the moisture in the damp desiccant; and the standby process ·· - After the recycling process, the {switching' allows the high-temperature desiccant to cool naturally; after the t-knives change the process of the tank, the humid compressed air = the converter completes the standby process. In the tank, the re-tolerance tank is introduced: the dry process is not completed and the other process of the regeneration process is completed. The tank will enter the standby flow 9. As for the completion of the process, the process of regeneration is carried out.
