[0001] The invention relates to the technical field of gas purification and drying, and in particular to a zero-gas-consumption blast heat regeneration drying device. Background Art

[0002] At present, compared with other types of adsorption dryers, air-blast regeneration adsorption dryers have the advantages of small pressure loss, small regeneration gas consumption, low comprehensive energy consumption and low operating costs, and are widely used in various fields that require gas. While the existing air-blast regeneration adsorption dryers desorb desiccant from high-temperature air, impurities such as dust, oil, and water vapor contained in them are easily mixed into the adsorbent, which will affect the service life of the dryer.

[0003] The prior art CN204182272U discloses a zero-gas-consumption negative-pressure regeneration combined dryer with heat recovery, which allows the regenerated gas from the refrigerated dryer to enter the adsorption tower through the negative-pressure action of a vacuum pump, and the dried air finally returns to the refrigerated dryer, thereby avoiding internal gas consumption and having an energy-saving effect. During the whole process, a filter is provided to filter impurities in the air, thereby avoiding the impurities in the air from affecting the service life of the dryer.

[0004] However, the impurity air filter components of the above-mentioned dryers are all arranged at the outlet of the adsorption tower. Although they can filter and remove dust from the finished dry gas, they cannot prevent the impurities in the air from affecting the adsorption tower and the components at the front end of the adsorption tower. Summary of the invention

Although the finished dry gas can be filtered and dusted, it cannot avoid the technical problem that the impurities in the air affect the adsorption tower and the components at the front end of the adsorption tower.

[0006] To achieve the above-mentioned objectives, the present invention provides a zero-gas-consumption blast heat regeneration drying device, comprising a double-tower drying mechanism, an air filtering mechanism, a blower, a fixed plate and a filter plate, the double-tower drying mechanism and the blower are connected through the air filtering mechanism, the blower has an air inlet, a fixed plate is arranged at the air inlet of the blower, and the filter plate is disassembled and arranged on the side of the fixed plate away from the air inlet; the air filtering mechanism comprises a filter chamber, a filter screen, an adsorption layer and an oil absorption layer, the filter chamber is connected to the blower and is located on the side of the blower close to the double-tower drying mechanism, and the filter screen, the adsorption layer and the oil absorption layer are arranged in the filter chamber from top to bottom in sequence.

[0007] Wherein, the filter screen, the adsorption layer and the oil absorption layer are all disassembled and arranged in the filter chamber, so as to facilitate timely replacement of the filter screen, the adsorption layer or the oil absorption layer with a new one.

[0008] Wherein, the filter plate includes a plate body and a buckle, the fixing plate has a slot, the buckle is arranged on a side of the plate body close to the fixing plate and embedded in the slot to achieve a snap connection between the buckle and the slot.

The regeneration tower is connected to the filter chamber and is located on the side of the filter chamber away from the blower. The adsorption tower is connected to the regeneration tower through the cooling and separation component.

[0010] Among them, the cooling and separation component includes a cooling chamber and a gas-liquid separation chamber. The cooling chamber is connected to the regeneration tower and is located on the side of the regeneration tower away from the filter chamber. The two sides of the gas-liquid separation chamber are respectively connected to the cooling chamber and the adsorption tower.

DETAILED DESCRIPTION

[0021] Embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be construed as limiting the present invention.

[0022] First embodiment:

[0023] See also Figures 1 to 5 The present invention provides a zero-gas-consumption blast heat regeneration drying device, comprising a double-tower drying mechanism, an air filtering mechanism, a blower, a fixing plate 101 and a filter plate, wherein the air filtering mechanism comprises a filter chamber 102, a filter screen 103, an adsorption layer 104 and an oil absorption layer 105, the filter plate comprises a plate body 106 and a buckle 107, the double-tower drying mechanism comprises a regeneration tower 108, a cooling and separation component and an adsorption tower 109, the cooling and separation component comprises a cooling chamber 110 and a gas-liquid separation chamber 111, and the blower comprises a housing 112, a rotating rod 113 and a rotating blade 114.

[0024] In this embodiment, the present invention sets the filter plate before the air is sucked into the blower, so that the filter plate can perform preliminary filtering on impurities in the air. When the air is sucked into the blower and transmitted to the filter chamber 102 by the blower, the impurities in the air can be filtered again through the coordinated use of the filter mesh 103, the adsorption layer 104 and the oil absorption layer 105, thereby improving the air purification effect to avoid the impurities contained in the air from affecting the service life of the drying equipment. Since the filtration of impurities in the air occurs before and after the air enters the blower and before the double-tower drying mechanism, the impurities in the air are avoided from affecting the normal use of the double-tower drying mechanism, which solves the technical problem that the impurity air filter components of the existing dryers are all set at the outlet of the adsorption tower 109. Although the finished dry gas can be filtered and dusted, the impurities in the air cannot be avoided from affecting the adsorption tower 109 and the components at the front end of the adsorption tower 109.

[0025] The twin-tower drying mechanism and the blower are connected via the air filtering mechanism, the blower has an air inlet, a fixing plate 101 is arranged at the air inlet of the blower, and the filter plate is disassembled and arranged on the side of the fixing plate 101 away from the air inlet; the filter chamber 102 is connected to the blower and is located on the side of the blower close to the twin-tower drying mechanism, and the filter screen 103, the adsorption layer 104 and the oil absorption layer 105 are arranged in sequence from top to bottom in the filter chamber 102.

[0026] Secondly, the filter 103, the adsorption layer 104 and the oil absorption layer 105 are all disassembled and arranged in the filter chamber 102, so as to facilitate timely replacement of the new filter 103, the adsorption layer 104 or the oil absorption layer 105. Parts of the filter 103, the adsorption layer 104 and the oil absorption layer 105 are all extended out of the filter chamber 102, so as to achieve the purpose of quickly extracting the filter 103, the adsorption layer 104 or the oil absorption layer 105 from the filter chamber 102 when disassembling. 103 is evenly distributed with filter holes, and the filter holes of the filter 103 can filter impurities in the air, so that the filtered air passes through the filter holes of the filter 103, and the filtered impurities are retained on the filter 103. The adsorption layer 104 is made of activated carbon particles, and the oil absorption layer 105 is made of polypropylene fiber. The activated carbon layer can effectively absorb dust by utilizing its porous structure, and the polypropylene has strong hydrophobicity and good adsorption capacity for oil stains, thereby effectively adsorbing oil stains.

[0027] Again, the fixing plate 101 has a slot 116, and the buckle 107 is arranged on a side of the plate body 106 close to the fixing plate 101 and embedded in the slot 116 to achieve a snap connection between the buckle 107 and the slot 116. The plate body 106 is evenly distributed with filter holes, and the filter holes of the plate body 106 can filter impurities in the air, so that the filtered air passes through the filter holes of the plate body 106, and the filtered impurities are retained outside the plate body 106. The filter hole size of the plate body 106 is larger than the filter hole size of the filter net 103, so that the plate body 106 can preliminarily filter the solid particle impurities in the air, and the filter net 103 can filter the solid particle impurities in the air again.

[0028] Meanwhile, the regeneration tower 108 is communicated with the filter chamber 102 and is located at a side of the filter chamber 102 away from the blower. The adsorption tower 109 is communicated with the regeneration tower 108 via the cooling and separation assembly.

[0029] In addition, the cooling chamber 110 is connected to the regeneration tower 108 and is located on the side of the regeneration tower 108 away from the filter chamber 102. The two sides of the gas-liquid separation chamber 111 are respectively connected to the cooling chamber 110 and the adsorption tower 109. The gas-liquid separation chamber 111 is located between the cooling chamber 110 and the adsorption tower 109.

[0030] In addition, an exhaust pipe 117 is provided at the bottom of the adsorption tower 109, and the exhaust pipe 117 is used to discharge the treated gas to the gas use site.

[0031] Finally, the rotating rod 113 is rotationally connected to the shell 112 and passes through the shell 112. The rotating blade 114 is arranged on the outside of the rotating rod 113 and is located inside the shell 112. The rotation of the rotating rod 113 in the shell 112 is driven by a driving motor 115. The output end of the driving motor 115 is connected to the rotating rod 113 through a coupling and is arranged outside the shell 112. The output end of the driving motor 115 is connected to the rotating rod 113 through a coupling, and drives the rotating rod 113 to rotate along its own axis in the shell 112, thereby driving the rotating blade 114 to rotate along the axis of the rotating rod 113 in the shell 112, and then air can be sucked into the shell 112 from the air inlet.

[0032] When using a zero-gas-consumption blast heat regeneration drying device of the present embodiment, the buckle 107 is embedded in the card slot 116, so that the plate body 106 is limited and fixed on the outside of the fixed plate 101, and the filter screen 103 is installed on the outside of the fixed plate 101. After the filter screen 103 is installed, the drive motor 115 is started, so that the power output by the output end of the drive motor 115 drives the rotating rod 113 to rotate along its own axis in the shell 112, thereby driving the rotating blade 114 to rotate along the axis of the rotating rod 113 in the shell 112, and then the air can be gradually sucked into the plate body 106 from the air inlet. At this time, the filter holes of the plate body 106 can filter impurities in the air, so that the filtered air passes through the filter holes of the plate body 106 into the shell 112, and the filtered impurities are left outside the plate body 106, thereby realizing preliminary filtration of the air.

[0033] After the air enters the shell 112, the rotating blades 114 continue to rotate, so that the air in the shell 112 can be gradually transmitted to the filter chamber 102 and reach the filter 103, so that the filter holes of the filter 103 can filter the impurities in the air, so that the filtered air passes through the filter holes of the filter 103, and the filtered impurities are retained on the filter 103. After filtering, the air can effectively adsorb dust in the adsorption layer 104, and then effectively adsorb oil in the oil absorption layer 105, so as to achieve re-filtration of the air, thereby improving the air purification effect, so as to avoid the impurities contained in the air affecting the service life of the drying equipment.

[0034] After the air is purified, the air can be gradually transmitted from the filter chamber 102 to the regeneration tower 108, and heated and regenerated in the regeneration tower 108. Thereafter, the air passes through the cooling chamber 110 and the gas-liquid separation chamber 111 in turn, so that the air after heating and regeneration can be cooled and separated in the cooling chamber 110 and the gas-liquid separation chamber 111 in turn. The separated air will be transmitted to the adsorption tower 109 for adsorption, and after adsorption, it will be discharged from the exhaust pipe 117 to the gas usage site.

[0035] When a large amount of impurities accumulate on the filter plate, the filter net 103, the adsorption layer 104 and the oil absorption layer 105, the buckle 107 is removed from the card slot 116, so that the limited fixed state of the plate body 106 on the fixed plate 101 is released, thereby realizing the disassembly of the filter plate, so as to facilitate the timely replacement of the filter plate; the filter net 103, the adsorption layer 104 or the oil absorption layer 105 is taken out of the filter chamber 102, so that the filter net 103, the adsorption layer 104 or the oil absorption layer 105 can be disassembled, so as to facilitate the timely replacement of the filter net 103, the adsorption layer 104 or the oil absorption layer 105.

[0036] What is disclosed above is only one or more preferred embodiments of the present application, and cannot be used to limit the scope of rights of the present application. Ordinary technicians in this field can understand that all or part of the processes of implementing the above embodiments and equivalent changes made according to the claims of the present application are still within the scope covered by the present application.
