Description

Technical Field

[0001] The utility model relates to the technical field of dryers, in particular to an energy-saving blast heat zero-gas-consumption regenerative adsorption dryer. Background Art

[0002] As people's living standards continue to improve, the requirements for air utilization and purification are also getting higher and higher. Currently, compressed air dryers can be roughly divided into two types: refrigeration dryers and adsorption dryers. Refrigeration dryers use the refrigeration principle to cool the compressed air and separate the water vapor in it for drying. The system air supply of this type of dryer is 100%, but the dew point can only reach 2 degrees Celsius to 10 degrees Celsius. Once the dew point is required to be below 0 degrees Celsius, an adsorption dryer must be used. The adsorption dryer cools the high-temperature compressed air through an aftercooler, cools and regenerates the adsorbent after high-temperature desorption, and then passes through another adsorption tower for adsorption and output as finished gas, thus achieving the purpose of "zero gas consumption" and saving energy to the greatest extent.

[0003] At present, when the existing dryer is in use, due to its internal regeneration pipeline, it is unable to evenly distribute the heating and cooling, resulting in the adsorption heat in the center of the adsorption tower being dispersed, which easily leads to incomplete regeneration.

[0004] Therefore, we have made improvements to this and proposed an energy-saving blast heat zero gas consumption regeneration adsorption dryer. Utility Model Content

[0005] In order to solve the problem of incomplete regeneration that easily occurs in the existing dryer, the utility model provides an energy-saving blast heat zero gas consumption regeneration adsorption dryer.

[0006] The utility model is achieved in this way:

[0007] An energy-saving blast heat zero gas consumption regenerative adsorption dryer includes a pair of adsorption towers, the top ends of the pair of adsorption towers are respectively connected to a hot flow channel, and the bottom ends of the pair of adsorption towers are respectively connected to a cold flow channel. A regeneration pipeline is provided between the hot flow channel and the cold flow channel. The regeneration pipeline includes an outer tube, an inner tube, a through hole, a plurality of first air holes and a plurality of second air holes. The top end of the outer tube is connected to one end of the hot flow channel, the bottom end of the inner tube is connected to one end of the cold flow channel, and one end of the inner tube is inserted and connected to the interior of the outer tube. The outer wall of the outer tube is provided with a plurality of first air holes, and the outer wall of the inner tube is provided with a plurality of second air holes.

[0008] Furthermore, the bottom end of the heat flow channel is connected to a first branch pipe, and one end of the first branch pipe is provided with a sensing mechanism.

[0009] The beneficial effect of adopting the above further solution is that, through the communication with the first branch pipe, the heat flow channel and the sensing mechanism form an air flow connection.

[0010] Furthermore, a fixing rod is welded between the pair of adsorption towers, and one end of the fixing rod is connected to the outer wall of the sensing mechanism.

[0011] The beneficial effect of adopting the above further solution is that the sensing mechanism can be easily fixed by welding the fixing rod.

[0012] Furthermore, the outer wall of the cold flow channel is connected to a second branch pipe, and one end of the second branch pipe is connected to the bottom end of the sensing mechanism.

[0013] The beneficial effect of adopting the above further solution is that, through the communication with the second branch pipe, the cold flow channel and the sensing mechanism form an airflow connection.

[0014] Furthermore, the sensing mechanism includes a top box, a bottom box, a display screen, a first interface and a second interface. The bottom end of the top box is connected to the top end of the bottom box. A temperature and humidity sensor is installed at the connection between the top box and the bottom box. A display screen is embedded on one side of the outer wall of the top box.

[0015] The beneficial effect of adopting the above further solution is that by installing and using the temperature and humidity sensor, it is convenient to monitor the temperature changes inside the top box and the bottom box in real time, and by installing and using the display screen, it is convenient to observe the temperature change value in real time.

[0016] Furthermore, a first interface is provided at the top of the top box, and one end of the first interface is connected to one end of the first branch pipe.

[0017] Furthermore, a second interface is provided at the bottom end of the bottom box, and one end of the second interface is connected to one end of the second branch pipe.

[0018] Furthermore, a pair of adsorption towers are provided with a base frame at the bottom end, and the base frame includes a frame body, support rods and support legs. The support rods are welded to the top end of the frame body, one end of the support rod is connected to the outer wall of the adsorption tower, and the support legs are welded to the bottom end of the frame body.

[0019] The beneficial effect of adopting the above further solution is that the adsorption tower can be easily fixed by welding the support rods.

[0020] Furthermore, pressure gauges are respectively embedded and installed on both sides of the outer walls of a pair of the adsorption towers, and the detection ends of the two pressure gauges extend to the interior of the adsorption towers respectively.

[0021] The beneficial effect of adopting the above further solution is that, by installing and using a pressure gauge, it is convenient to monitor the pressure changes inside the adsorption tower in real time.

[0022] The beneficial effects of the present invention are as follows: through the coordinated use of the hot flow channel, the cold flow channel and the regeneration pipeline, the hot flow and the cold flow inside the dryer are balanced, so that they can be released in the center of the adsorption tower, which is conducive to bottom regeneration. Among them, through the connection between the hot flow channel and the outer tube, the hot flow is output to the interior of the adsorption tower, and through the connection between the cold flow channel and the inner tube, the cold flow is output to the interior of the adsorption tower, and through the positional relationship in which one end of the inner tube is inserted and connected to the interior of the outer tube, the first air hole and the second air hole can release air flow alternately from the same central area. Through such a structure, it is ensured that the regeneration gas can be evenly distributed during plane heating and cold blowing of the regeneration gas, so that the adsorption heating in the center of the adsorption tower is uniform, the heat dissipation is fast, and the regeneration is thorough.
