Description

Technical Field

[0001] This utility model relates to the field of dryer technology, specifically to a compression heat regeneration adsorption dryer. Background Technology

[0002] An adsorption dryer is a device that uses adsorbents (such as activated alumina, silica gel, molecular sieves, etc.) to adsorb moisture from compressed air, thereby reducing air humidity. Its working principle is based on the adsorption and desorption process of the adsorbent under pressure changes, and it can typically reduce the dew point of the outlet air to -40℃ to -70℃.

[0003] Adsorption dryers achieve drying through pressure changes (pressure swing adsorption principle). Air's capacity to hold moisture is inversely proportional to its pressure; therefore, when the dried air is depressurized and expands to atmospheric pressure, it becomes even drier. This dried air (called regenerated air) flows through the desiccant layer that is not connected to the airflow, drawing out moisture from the desiccant and thus achieving dehumidification. The two towers operate in a cycle, requiring no heat source, and can continuously supply dry compressed air to the user's air supply system.

[0004] Currently, zero-gas-consumption compression heat regeneration adsorption dryers typically install a full-flow heater directly on the main pipeline to heat the gas flow to a suitable temperature. However, due to the high power of the heater, the energy-saving effect of the dryer is significantly reduced. Therefore, there is an urgent need to design a compression heat regeneration adsorption dryer to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a compression heat regeneration adsorption dryer to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A compression heat regeneration adsorption dryer includes a base, on the upper side of which a first tower and a second tower are disposed, the first tower corresponding to the second tower. A first post-cooler and a second post-cooler are disposed on the upper side of the base, the first post-cooler corresponding to the first tower and the second post-cooler corresponding to the second tower. A first gas-liquid separator and a second gas-liquid separator are disposed on the upper side of the base, the first gas-liquid separator corresponding to the first post-cooler and the second gas-liquid separator corresponding to the second post-cooler. A silencer is disposed on the upper side of the base, the silencer corresponding to the first tower.

[0010] Both the first and second rear coolers have a cooling water outlet and a cooling water inlet on one side.

[0012] Both the first gas-liquid separator and the second gas-liquid separator are provided with an automatic discharge port and a manual discharge port on one side, and the automatic discharge port and the manual discharge port correspond to each other.

[0013] In the above technical solution, the beneficial effects of the compression heat regeneration adsorption dryer provided by this utility model are as follows:

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1-4 As shown in the figure, the compression heat regeneration adsorption dryer provided in this embodiment of the utility model includes a base 1, a first tower 2 and a second tower 3 are arranged on the upper side of the base 1, the first tower 2 corresponds to the second tower 3, a first rear cooler 4 and a second rear cooler 5 are arranged on the upper side of the base 1, the first rear cooler 4 corresponds to the first tower 2 and the second rear cooler 5 corresponds to the second tower 3, a first gas-liquid separator 6 and a second gas-liquid separator 7 are arranged on the upper side of the base 1, the first gas-liquid separator 6 corresponds to the first rear cooler 4. A silencer 8 is provided on the upper side of the base 1 corresponding to the second gas-liquid separator 7 and the second aftercooler 5. The silencer 8 corresponds to the first tower 2. The output end of the first tower 2 is connected to the input end of the first aftercooler 4. The output end of the first aftercooler 4 is connected to the output end of the first gas-liquid separator 6. The output end of the first gas-liquid separator 6 is connected to the input end of the second tower 3. The output end of the second aftercooler 5 is connected to the input end of the second gas-liquid separator 7. The output end of the second gas-liquid separator 7 is connected to the input end of the second tower 3.

[0024] Specifically, in this embodiment, the compressor is fixedly connected to the air inlet 9 of the dryer, so that the high temperature and desaturated humid air discharged from the compressor directly enters the dryer through the air inlet 9 for drying and compression. The humid air first enters the first tower 2 of the dryer through the air inlet 9 to heat and regenerate the desiccant. The regenerated gas enters the first aftercooler 4 for cooling, and then enters the first gas-liquid separator 6 to separate liquid water. Finally, it enters the second tower 3 for drying and adsorption to obtain dry gas. The dried compressed air is discharged from the air outlet 10, which is fixedly connected to the usage pipeline network, so that the dried gas enters the usage pipeline network.

[0025] After 150 minutes, the heated first tower is bypassed by the bypass valve, allowing the high-temperature, desaturated, humid air discharged from the compressor to directly enter the second aftercooler 5 for cooling. After cooling, it enters the second gas-liquid separator 7, where liquid water is separated. Finally, it enters the second tower 3 for drying and adsorption to obtain dry gas. The dried compressed air is then discharged from the air outlet 10, allowing the dry gas to enter the usage pipeline network. At the same time, during this stage, a portion of the airflow is drawn through the throttling orifice at the air outlet 10 to complete the cold blowing and cooling of the regeneration tower. Then, this small portion of the airflow is finally discharged into the atmosphere through the silencer 8.

[0026] After 85 minutes, the cold blowing ends and the pressure increases; after 5 minutes, the pressure in both towers is balanced, and after 4 hours, the dual-tower dryer begins the regeneration process of the other tower. If the dryer is in dew point monitoring mode, it switches according to the outlet dew point after the pressure increase to save air consumption. This dryer fully utilizes the heat from the high-temperature exhaust of the air compressor to heat and regenerate the adsorbent, eliminating the need for the electric heater in the micro-heat regeneration adsorption dryer, thus saving on electricity consumption. The power consumption is only 0.25 kW per hour. At the same time, since there is no air consumption during heating and regeneration, energy is saved to the greatest extent.

[0027] The compression heat regeneration adsorption dryer provided by this utility model has a first tower 2 with a manual drain port 18 on one side and a second tower 3 with a manual drain port 17 on one side. The first rear cooler 4 and the second rear cooler 5 each have a cooling water outlet 11 and a cooling water inlet 12 on one side. The first rear cooler 4 and the second rear cooler 5 each have an automatic cooler outlet 15 and a manual cooler outlet 16 at one end, with the automatic outlet 15 and the manual outlet 16 corresponding to each other. The first gas-liquid separator 6 and the second gas-liquid separator 7 each have an automatic separator outlet 13 and a manual separator outlet 14 on one side, with the automatic separator outlet 13 and the manual separator outlet 14 corresponding to each other.

[0028] In another embodiment of this utility model, the manual drain outlet 17 of the second tower and the manual drain outlet 18 of the first tower are used to discharge the generated sewage, the cooling water outlet 11 and the cooling water inlet 12 are used to enable the cooling water to circulate and improve the cooling effect, the automatic drain outlet 15 and the manual drain outlet 16 of the cooler can discharge the condensate generated by the first rear cooler 4 and the second rear cooler 5, and the automatic drain outlet 13 and the manual drain outlet 14 of the separator can discharge the liquid water separated in the first gas-liquid separator 6 and the second gas-liquid separator 7.

[0029] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
