DETAILED DESCRIPTION

[0028] The embodiment of the present invention provides a novel zero-gas consumption adsorption dryer, such as Figure 1-6 As shown, it includes a supporting base 101, two drying towers 111, a storage tank 117 and an air pump group 118. The two drying towers 111 are set up on one side of the supporting base 101, and the drying towers 111 on both sides are symmetrically arranged.

The air pump group 118 is set up between the drying tower 111 and the storage tank 117, and one side of the outer end face of the storage tank 117 is connected with a product output pipe 121.

[0029] It should be further explained that the switch 115 can adjust the connectivity between the product gas pipes 113, the product storage pipe 116 and the connecting pipe 107 on both sides by rotating.

[0030] Furthermore, a drying chamber 122 is provided in the drying towers 111 on both sides. The drying chamber 122 is trapezoidal and has a plurality of molecular plates 124 arranged in an array from top to bottom. The inner circumference of the molecular plates 124 is provided with open and connected air flow holes 123 .

[0031] It should be further explained that the molecular plate 124 is filled with a high-efficiency adsorbent, which can adsorb the moisture in the input humid air to achieve the effect of drying the air.

[0032] Furthermore, a heating plate 106 is fixedly provided on the outer end surface of the drying tower 111, and a spiral pipe 103 with an annular thread shape is provided inside the heating plate 106. The top end of the spiral pipe 103 is connected to an output pipe 110, and the tail ends of the output pipes 110 on both sides are connected to the same return pipe 102, and the middle position of the return pipe 102 is connected to the connecting pipe 107.

[0033] Furthermore, the output pipes 110 on both sides are connected to the air intake pipe at the bottom of the storage tank 117 .

[0034] Furthermore, a heating plate is provided inside the heating plate 106 , and the heating plate 106 can heat the interior of the drying chamber 122 .

[0035] It should be further explained that the connection position between the heating plate 106 and the drying tower 111 is made of heat exchange material.

[0036] Furthermore, an exhaust hole 108 is provided on the upper side of the outer end surface of the drying tower 111 , and the exhaust hole 108 is connected to the inner wall of the drying chamber 122 . An on-off valve 109 is provided in the exhaust hole 108 .

[0037] It is worth further explaining that the rotating on-off valve 109 can control the on-off status of the exhaust hole 108 .

[0038] Furthermore, an airflow detector 112 is provided at the top of the drying tower 111 , and the airflow detector 112 can detect the flow rate of the gas flowing through the product gas pipe 113 .

[0039] Furthermore, a flow divider 119 is connected to the front end of the air pump assembly 118 , and two flow divider pipes 120 are connected to the end surfaces on both sides of the flow divider 119 .

[0040] Furthermore, stabilizing brackets 105 are fixedly provided at both ends of the support base 101, and the stabilizing brackets 105 on both sides are symmetrically arranged. An input pipe port 104 is connected to the bottom of the drying tower 111, and the input pipe port 104 passes through the stabilizing bracket 105, and the stabilizing bracket 105 plays a role of stabilizing support.

[0041] Furthermore, the input pipe opening 104 is connected to the flow diversion pipe 120 via a connecting pipe.

[0042] It should be further explained that the inlet of the air pump assembly 118 is connected to the output pipe opening of the wet air tank to be dried.

[0043] When using this solution, first start the air pump group 118 and draw the wet air in the wet air tank into the wet air tank and divert it through the diverter 119, and then output the wet air to the connected input pipe port 104 through the diversion pipe 120, and input the wet air into the drying chamber 122 in the drying tower 111 through the input pipe port 104. As the wet air flows from bottom to top, the wet air is adsorbed by the array molecular plates 124, and guided by the trapezoidal drying chamber 122, the wet air is gradually enriched upward. During the output process, the wet air is subjected to multiple moisture adsorption, and finally the dry gas product is output to the outside through the product gas pipe 113 to the pipeline switching valve 114, and input into the connected product storage pipe 116, and the dry gas product is input into the storage tank 117 for storage.

[0044] After the drying towers 111 on both sides have been working for a period of time, the internal molecular plate 124 has absorbed a lot of water. The staff turns the switch 115 on the top. At this time, the pipeline switching valves 114 on both sides are disconnected, and the product storage pipe 116 is connected to the connecting pipe 107. At the same time, the staff opens the on-off valve 109 and connects the exhaust hole 108 to the outside. At this time, the heating plate 106 is started in the heating plate 106, and the heating plate 106 can heat the inside of the drying chamber 122. At this time, as the inside of the drying chamber 122 is heated, the water molecules in the adsorption material in the molecular plate 124 evaporate and are output to the outside through the exhaust hole 108 with the air flow. After a period of adsorbent regeneration work, as the heating plate 106 and the surface of the drying tower 111 are attached to the temperature inside the drying chamber 122 for heat exchange, the heating plate 1 06 is exchanged to the spiral pipe 103. At this time, the air in the spiral pipe 103 heats up and expands, and the air is promoted to flow into the storage tank 117 through the output pipe 110. At this time, the product gas in the storage tank 117 is input upward into the product storage pipe 116 due to the air flow, and is input into the pipeline switching valve 114 through the product storage pipe 116, and is input into the return pipe 102 through the connected connecting pipe 107, and finally the product gas flows into the tail end of the spiral pipe 103, so as to realize the circulation of the product gas, and the product gas is used to perform heat exchange with the heating plate 106 and the inside of the drying chamber 122, so as to promote the cooling of the inside of the drying chamber 122, and further facilitate the internal cooling of the drying tower 111, so as to facilitate the subsequent drying work, realize zero gas consumption, and further reduce energy consumption.
