Description

Technical Field

[0001] The utility model relates to the technical field of compressed air dryers, and more particularly to a silencer device for adsorption drying equipment. Background Art

[0002] Compressed air is widely used in the hydrometallurgical industry. The compressed air produced by the screw air compressor is buffered and condensed in an air tank, and then dried by an adsorption drying device at the rear end of the air tank to meet the usage standards. The adsorption dryer uses an adsorbent to remove moisture from the compressed air. Currently, during the adsorption drying and regeneration process of compressed gas, the regenerated gas has a certain pressure when it is discharged, and the exhaust speed is relatively fast, which causes gas vibration and produces strong exhaust noise, generally reaching 80-110dB. This gas emission is not only loud, but also contains small amounts of water, oil and impurities in the gas, which splash everywhere, bringing adverse effects to both the on-duty personnel and the on-site production environment. Utility Model Content

[0003] The purpose of the present invention is to solve the above technical problems and provide a silencer for adsorption drying equipment, which reduces the noise of regeneration gas during discharge and discharges regeneration gas and moisture in a centralized manner, making it easier for staff to maintain and overhaul the equipment in the later stage.

[0004] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions: a silencer device for adsorption drying equipment, comprising a detachable silencer structure, wherein the detachable silencer structure comprises an inner silencer and an outer silencer, wherein one end of the inner silencer is open and the other end is closed, the open end of the inner silencer is installed with the regeneration gas outlet end of the adsorption drying equipment, and the outer silencer is sheathed on the outer side of the closed end of the inner silencer, a plurality of noise reduction holes are opened on the outer wall of the inner silencer, and the plurality of noise reduction holes are all located inside the outer silencer, and the lower side of the outer silencer is fixedly connected to a centralized exhaust pipe.

[0007] In order to improve the noise reduction effect of the silencer, as a preferred silencer of the adsorption drying equipment of the present invention, the multiple noise reduction holes are evenly arranged, and the hole diameter is 10 mm, and the holes are spaced 10 mm apart.

[0008] In order to form a buffering resistance for the regeneration gas and prevent the liquid in the gas from refluxing, as a preferred silencer device of the adsorption drying equipment of the utility model, the angle a between the centralized exhaust pipe and the outer silencer is 15°.

[0009] The beneficial effects of the utility model are as follows:

[0010] 1. By providing a noise reduction device for the regeneration gas of the micro-heat regeneration drying equipment at the rear end of the gas storage tank, the compressed air is adsorbed and regenerated, reducing the water content of the compressed air, thereby providing users with a dry, high-quality and stable air source, ensuring the stable operation of the air-using equipment, and reducing the noise of the regeneration gas when it is discharged;

[0019] See also Figure 1-3 The utility model provides the following technical solutions: a silencer device for an adsorption drying equipment, comprising a detachable silencer structure 9, the detachable silencer structure 9 comprising an inner silencer 901 and an outer silencer 902, one end of the inner silencer 901 being open and the other end being closed, the open end of the inner silencer 901 being installed with the regeneration gas outlet end of the adsorption drying equipment, the outer silencer 902 being sheathed on the outer side of the closed end of the inner silencer 901, a plurality of noise reduction holes 9013 being opened on the outer wall of the inner silencer 901, the plurality of noise reduction holes 9013 being all located inside the outer silencer 902, and a centralized exhaust pipe 9022 being fixedly connected to the lower side of the outer silencer 902.

[0020] In this embodiment: when the regeneration gas is discharged from the adsorption drying equipment, the gas enters the detachable silencer structure 9, first passes through the inner silencer 901 and through the multiple noise reduction holes 9013. The multiple noise reduction holes 9013 form resistance to the regeneration gas, thereby causing a small amount of water, oil and impurities in the gas to settle and be discharged into the outer silencer 902 through the holes. The regeneration air enters the outer silencer 902 and is subjected to secondary resistance. Finally, the regeneration air, water, oil and impurities are all discharged through the centralized discharge pipe 9022. The setting of the outer silencer 902 can achieve a secondary noise reduction effect.

[0021] As a technical optimization solution of the present invention, a first flange 9011 is fixed to the open end of the inner silencer 901, and the first flange 9011 is installed with the regeneration gas outlet flange of the adsorption drying equipment.

[0022] In this embodiment, the inner silencer 901 is detachably connected to the regeneration gas outlet end by a flange, thereby making it convenient for workers to install and disassemble the entire detachable silencer structure 9 so as to replace a new silencer.

[0023] As a technical optimization solution of the present invention, a second flange 9012 is fixed to the outside of the inner silencer 901, and a third flange 9021 is fixed to the outside of the port where the outer silencer 902 and the inner silencer 901 are connected, and the second flange 9012 and the third flange 9021 are installed.

[0024] In this embodiment, the outer silencer 902 and the inner silencer 901 are detachably connected by a flange, which makes it convenient for workers to disassemble the inner and outer silencers for cleaning the inside of the silencer.

[0025] As a technical optimization solution of the present invention, multiple noise reduction holes 9013 are evenly arranged, with a hole diameter of 10 mm and a hole spacing of 10 mm; the angle a between the centralized exhaust pipe 9022 and the outer silencer 902 is 15°.

[0026] In this embodiment: by providing multiple noise reduction holes 9013 with smaller apertures, the reflection and resonance of the sound of the pressurized regeneration gas can be effectively eliminated. At the same time, the small distance between the holes can facilitate the circulation of the regeneration gas; the generated sound, gas, moisture and impurities are discharged through the centralized discharge pipe 9022, and the discharge inclination angle is designed to be 15°, which can avoid water accumulation and backflow in the silencer, and is also convenient for taking over the centralized collection to the system sewage tank.

[0027] The above is a detailed introduction to the technical solutions provided by the embodiments of the present invention. Specific examples are used herein to illustrate the principles and implementation methods of the embodiments of the present invention. The description of the above embodiments is only applicable to help understand the principles of the embodiments of the present invention.
