Description

Technical Field

[0001] The utility model belongs to the technical field of compressed air drying equipment, in particular to a double-tower dryer without air consumption. Background Art

[0002] Compressed air drying equipment is a device used to remove moisture from compressed air. Adsorption drying equipment is a commonly used treatment equipment. Adsorption drying equipment uses adsorbents (such as activated alumina, silica gel, molecular sieves, etc.) to adsorb moisture in compressed air to achieve the purpose of drying. When the adsorbent is saturated with adsorption, it needs to be regenerated, but it still has the following disadvantages in actual use:

[0003] 1. When working with adsorption drying equipment, after compressed air is introduced for drying in one use cycle, the adsorbent is regenerated and dry air needs to be introduced for drying. During the drying process, there is additional loss of compressed air, which makes the use more complicated.

[0004] 2. Secondly, when the compressed air to be dried is directly passed into the dryer, the water content of the compressed air is very high, which causes a large loss of the adsorbent in the dryer. The adsorbent in the dryer will quickly become ineffective, resulting in a shorter drying cycle and higher energy consumption. Utility Model Content

[0005] The utility model aims to provide a double-tower dryer without gas consumption. By arranging an adsorption tower, an exhaust pipe, an air inlet pipe, a drainage chamber and a cooling jacket, the utility model solves the problems that the dryer needs to consume additional compressed air when drying compressed air, the use is complicated, the adsorbent in the dryer fails quickly, and the use cost is high.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a double-tower dryer without gas consumption, comprising an adsorption tower, an exhaust pipe, an air intake pipe, a drainage chamber and a cooling jacket, wherein the two adsorption towers are arranged side by side and vertically, an exhaust pipe is arranged above the adsorption tower, and an air intake pipe is arranged below the adsorption tower, one end of the air intake pipe and the exhaust pipe are both closed, and the other end of the air intake pipe is fixedly connected with the drainage chamber, a water-absorbing sponge is fixed in the drainage chamber, one end of the drainage chamber away from the air intake pipe is fixedly connected with a compression pipe, a cooling jacket is fixed on the peripheral side of the compression pipe, the interior of the cooling jacket is hollow and spiral blades are fixed therein, when working, the compressed air entering therein is dried through the adsorption tower, the dried air is discharged through the exhaust pipe, the compressed air is transported to the branch pipe through the air intake pipe, the condensed water of the compressed air input into the compression pipe is discharged through the drainage chamber, and the compressed air passing through the compression pipe is cooled down through the cooling jacket.

[0008] Furthermore, an adsorption filter element is vertically fixed in the adsorption tower, and air transmission space is reserved in the adsorption tower above and below the adsorption filter element. When the adsorption tower is working, the moisture in the air entering therein is fully adsorbed by the adsorption filter element.

[0009] Furthermore, the positions on the periphery of the exhaust pipe corresponding to the two adsorption towers are fixedly connected with air supply pipes, the bottom ends of the two air supply pipes are fixedly connected with the top ends of the two adsorption towers respectively, and the periphery of the air supply pipe is fixedly connected with an electric control valve 1. When the exhaust pipe is working, the dried compressed air in the adsorption tower is transported to the exhaust pipe through the air supply pipe, and the size of the compressed air delivery in the air supply pipe is controlled by the electric control valve 1.

[0010] Furthermore, the positions around the air intake pipe corresponding to the two adsorption towers are fixedly connected with branch pipes, the top ends of the two branch pipes are fixedly connected with the bottom ends of the two adsorption towers respectively, and the air intake pipe transports the air transported therein to the adsorption towers through the branch pipes.

[0011] Furthermore, an electrically controlled valve 2 is fixed on the circumference of the two branch pipes, an outlet pipe is fixedly connected on the circumference of the branch pipe between the adsorption tower and the electrically controlled valve 2, and an electrically controlled valve 3 is fixed on the circumference of the two outlet pipes. The delivery on and off of the branch pipe is controlled by the electrically controlled valve 2, and the air in the adsorption filter element in the drying adsorption tower is discharged through the outlet pipe, and the delivery on and off of the gas storage tank is controlled by the electrically controlled valve 3.

[0012] Furthermore, a water outlet pipe is fixedly connected to the lower part of the peripheral side of the drainage cavity, a water inlet pipe is fixedly connected to the edge of the peripheral side of the cooling jacket close to the drainage cavity, and a drain pipe is fixedly connected to the edge of the peripheral side of the cooling jacket away from the drainage cavity. The water inlet pipe and the drain pipe are arranged symmetrically with respect to the center of the cooling jacket in a top-down perspective. When the drainage cavity is working, water absorbed by the absorbent sponge is discharged through the water outlet pipe, cooling water is input into the cooling jacket through the water inlet pipe, and the cooling water is discharged through the drain pipe.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model solves the problem that the dryer needs to consume additional compressed air and is complicated to use in the process of drying compressed air by arranging an adsorption tower, an exhaust pipe and an air inlet pipe. In the exhaust pipe, 88% to 90% of the compressed air is discharged to the use equipment, and the remaining part is transported to another air pipe and enters the adsorption tower. At this time, the air outlet pipe is connected with the air. After the compressed air enters the adsorption tower of the adsorption filter element to be dried, it expands rapidly. The dry air passes through the adsorption filter element, takes away the moisture adsorbed in the adsorption filter element, and is then transported to the branch pipe and discharged through the exhaust pipe on the branch pipe, so that the adsorption filter element after work can restore its water absorption function. During operation, the dryer does not need to introduce additional compressed air, which is more convenient to use and saves the use cost.

[0015] 2. The utility model solves the problems of fast adsorbent failure and high use cost in the dryer by arranging an air inlet pipe, a drainage chamber and a cooling jacket. When the compressed air in the compression pipe is cooled, the generated condensed water enters the drainage chamber together with the compressed air. Most of the condensed water is absorbed by the water-absorbing sponge in the drainage chamber and then transported to the air inlet pipe. The condensed water in the water-absorbing sponge descends under the action of gravity and is discharged through the water outlet pipe, which greatly reduces the adsorbent failure rate and reduces the use cost of the dryer.

[0027] See also Figure 1-5 The utility model is a double-tower dryer without gas consumption, including an adsorption tower 1, an exhaust pipe 2, an air intake pipe 3, a drainage chamber 4 and a cooling jacket 5. The two adsorption towers 1 are arranged side by side and vertically. The adsorption tower 1 adsorbs the moisture in the compressed air entering therein through an adsorption filter element 101. An exhaust pipe 2 is arranged above the adsorption tower 1, and the dried air in the adsorption tower 1 is discharged through the exhaust pipe 2. An air intake pipe 3 is arranged below the adsorption tower 1, and the cooled air is transported to the branch pipe 301 through the air intake pipe 3. One end of the air intake pipe 3 and the exhaust pipe 2 are both closed, and the other end of the air intake pipe 3 is fixedly connected to the drainage chamber 4. One end of the exhaust pipe 2 is opened and connected to the delivery pipeline of the compressed air equipment. A water-absorbing sponge 401 is fixed in the drainage chamber 4. Condensed water is generated when the compressed air is cooled. After the condensed water enters the drainage chamber 4, the compressed air enters the intake pipe 3 through the water-absorbing sponge 401. The end of the drainage chamber 4 away from the intake pipe 3 is fixedly connected with a compression pipe 504. The end of the compression pipe 504 away from the drainage chamber 4 is connected to the output end of the compressed air equipment, and the compressed air is transported to the drainage chamber 4 after being cooled. A cooling jacket 5 is fixed on the peripheral side of the compression pipe 504. The air in the compression pipe 504 is cooled by the cooling jacket 5. The interior of the cooling jacket 5 is hollow and has spiral blades 501 fixed therein. The cooling water entering the cooling jacket 5 is spirally circulated and transported by the spiral blades 501.

[0028] Specifically, an adsorption filter element 101 is vertically fixed in the adsorption tower 1 , and air transmission space is reserved in the adsorption tower 1 above and below the adsorption filter element 101 . When the adsorption tower 1 is working, moisture in the compressed air entering the adsorption tower 1 is adsorbed by the adsorption filter element 101 .

[0029] Furthermore, the positions on the periphery of the exhaust pipe 2 corresponding to the two adsorption towers 1 are fixedly connected with an air supply pipe 201, the bottom ends of the two air supply pipes 201 are fixedly connected with the top ends of the two adsorption towers 1 respectively, and the periphery of the air supply pipe 201 is fixedly connected with an electric control valve 202, the exhaust pipe 2 is connected with the adsorption tower 1 through the air supply pipe 201, and the air supply on and off of the air supply pipe 201 is controlled by the electric control valve 202.

[0030] Furthermore, the positions on the sides of the air inlet pipe 3 corresponding to the two adsorption towers 1 are fixedly connected with branch pipes 301 , the top ends of the two branch pipes 301 are fixedly connected with the bottom ends of the two adsorption towers 1 , respectively, and the air inlet pipe 3 is connected with the adsorption towers 1 through the branch pipes 301 .

[0031] Furthermore, an electric-controlled valve 2 302 is fixed on the circumference of the two branch pipes 301, and an outlet pipe 303 is fixedly connected to the circumference of the branch pipe 301 between the adsorption tower 1 and the electric-controlled valve 2 302. An electric-controlled valve 3 304 is fixed on the circumference of the two outlet pipes 303. The electric-controlled valve 2 302 controls the on-off of the branch pipe 301 to transport compressed air to the adsorption tower 1, and when the drying air is discharged from the adsorption tower 1, the electric-controlled valve 3 304 on the outlet pipe 303 is opened, and the electric-controlled valve 2 302 is closed, and the air carrying away the moisture in the adsorption filter element 101 is discharged through the outlet pipe 303.

[0032] The operation process of this embodiment is as follows: during operation, after the water is absorbed by the water-absorbing sponge 401 in the drainage chamber 4, one of the electric-controlled valves 2 302 on the two branch pipes 301 on the air inlet pipe 3 is opened and the other is closed. At this time, the compressed air is transported to an adsorption tower 1 through a branch pipe 301, and is dried by the adsorption filter element 101 in the adsorption tower 1 and discharged into the air supply pipe 201. At this time, the electric-controlled valve 1 202 on the air supply pipe 201 is maintained open, and the other electric-controlled valve 1 202 is maintained closed. The dried compressed air is transported to the exhaust pipe 2 through the air supply pipe 201, and is transported to the user's equipment pipeline through the exhaust pipe 2. After an adsorption tower 1 has worked for 5 minutes, the electric-controlled valve 2 302 below it is closed, and the other electric-controlled valve 2 302 is opened, and the electric-controlled valve 3 304 above the closed electric-controlled valve 2 302 is opened, and the electric-controlled valve 3 304 above the other electric-controlled valve 2 302 is maintained closed, and both electric-controlled valves 1 202 are opened. And after 5 minutes of use, the opening degree of the electric control valve 202 is one-eighth of the full opening. The electric control valve 202 above the adsorption tower 1 that has just been used is fully opened. At this time, the compressed air enters the branch pipe 301 of the opened electric control valve 2 302 through the air inlet pipe 3, and is transported to the adsorption tower 1. Under the adsorption of the adsorption filter element 101, after absorbing moisture, it is transported to the air supply pipe 201 and then to the exhaust pipe 2. In the exhaust pipe 2, 88% to 90% is discharged to the use equipment, and the remaining part is transported to another air supply pipe 201 and enters the adsorption tower 1. At this time, the air outlet pipe 303 is connected with the air. After the compressed air enters the adsorption tower 1 of the adsorption filter element 101 to be dried, it expands rapidly. The dry air passes through the adsorption filter element 101, takes away the moisture adsorbed in the adsorption filter element 101, and is then transported to the branch pipe 301, and is discharged through the exhaust pipe 2 on the branch pipe 301, so that the adsorption filter element 101 after work restores the water absorption function and performs a working cycle.

The end of the water inlet pipe 502 away from the cooling jacket 5 is connected to the pipeline for conveying cooling water, and the end of the drain pipe 503 away from the cooling jacket 5 is connected to the pipeline for outputting cooling water after heat exchange. The water inlet pipe 502 and the drain pipe 503 are centrally symmetrically arranged with respect to the center of the cooling jacket 5 in a top view. When the drainage chamber 4 is working, water absorbed in the water-absorbing sponge 401 is discharged through the water outlet pipe 402. When the compression pipe 504 is transmitting gas, the cooling water enters the cooling jacket 5 through the water inlet pipe 502 and is discharged from the cooling jacket 5 through the drain pipe 503, so as to cool the compressed air in the compression pipe 504.

[0035] The operation process of this embodiment is as follows: during operation, when the air compressed by the compressed air equipment is transported in the compression pipe 504, the cooling water is transported to the cooling jacket 5 through the water inlet pipe 502, and the cooling water is spirally transported in the cooling jacket 5 through the spiral blades 501 in the cooling jacket 5. After the compressed air passing through the cooling jacket 5 is cooled, it is transported to the drain pipe 503 and discharged through the drain pipe 503. When the compressed air in the compression pipe 504 is cooled, the generated condensed water enters the drainage chamber 4 together with the compressed air, and after most of the condensed water is absorbed by the water-absorbing sponge 401 in the drainage chamber 4, it is transported to the air inlet pipe 3, and the condensed water in the water-absorbing sponge 401 descends under the action of gravity and is discharged through the water outlet pipe 402.
