[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] The utility model provides a device for recovering and utilizing waste heat from outlet gas of a compressor, comprising a compressor body 1, a recovery mechanism 2 for preheating and utilizing is provided on one side of the compressor body 1, a heat conduction mechanism 3 for improving the heat recovery rate is provided inside the recovery mechanism 2, a processing mechanism 4 for gas filtering is provided on one side of the recovery mechanism 2, and a heat preservation barrel 22 in the recovery mechanism 2 is provided at one end of the compressor body 1;

[0024] The support plate 31 in the heat conduction mechanism 3 is fixedly mounted on the inner wall of the heat preservation barrel 22 , a support rod 32 is fixedly mounted on the top of the support plate 31 , a copper tube 34 is fixedly mounted on the top of the support rod 32 , and a copper wire 35 is fixedly mounted on the inner side of the copper tube 34 .

[0025] It is used to achieve the advantages of heat energy transportation and comprehensive uniformity recovery, and at the same time it can also achieve the advantage of high recovery rate by transferring heat energy through adsorption heat conduction.

[0026] Preferably, the recovery mechanism 2 further includes an exhaust component and a discharge component. The exhaust component is arranged on the outside of the compressor body 1 , and the discharge component is arranged on the outside of the heat preservation barrel 22 .

[0027] like Figure 2As shown, the flange of the insulation pipe 21 in the exhaust assembly is connected to the exhaust end of the compressor body 1, and the exhaust end of the insulation pipe 21 is connected to the delivery pipe 26. The inner wall of the delivery pipe 26 is provided with an exhaust hole. The insulation pipe 21 will not cause much heat loss when used to transport gas, and the delivery pipe 26 is used to transport hot gas around and spray heat-containing gas in a surrounding manner, so as to cooperate with the storage barrel 23 to recycle heat.

[0028] like Figure 2 As shown, the storage barrel 23 in the discharge assembly is fixedly installed inside the insulation barrel 22, the top of one side of the insulation barrel 22 is connected to an exhaust pipe 24, the bottom end of the storage barrel 23 is connected to a drain pipe 25, and the delivery pipe 26 is located on the outside of the storage barrel 23. The insulation barrel 22 is used to insulate the temporary storage of gas, the exhaust pipe 24 is used to discharge the treated gas to a preset pipeline, and the drain pipe 25 is used to discharge through a water source heated by thermal energy.

[0029] When recycling the heat energy generated by the compressor body 1:

[0030] The heat energy gas is first discharged to the delivery pipe 26 through the connected insulation pipe 21. At this time, the delivery pipe 26 will transport and dissipate the heat energy in a surrounding manner. Due to the exhaust holes provided therein, it can also directly spray during the delivery process, causing the storage barrel 23 to absorb the heat energy, and increase the temperature of the storage barrel 23 and the internal water source, completing the heat energy recovery and utilization;

[0031] To improve thermal energy utilization and recovery efficiency:

[0032] The copper ring 33, copper tube 34 and copper wire 35 will absorb the heat into themselves when they come into contact with the gas containing heat, and then they will directly supply heat energy to the storage barrel 23 when they come into contact with the surface of the storage barrel 23, thereby increasing the efficiency and utilization rate of heat recovery and avoiding waste.

[0033] Furthermore, the processing mechanism 4 includes a support assembly and a filter assembly. The support assembly is arranged on one side of the heat preservation barrel 22, and the filter assembly is arranged inside the support assembly.

[0034] like Figure 4 As shown, the carrier plate 45 in the support assembly is fixedly installed on one side of the heat preservation barrel 22, and a connecting tube 44 is placed on the top of the carrier plate 45. An adapter hole is also opened on the top of the carrier plate 45 to play a supporting role and assist in disassembly and assembly operations.

[0035] like Figure 4 As shown, the filter assembly includes a connecting cover 41, which is threadedly connected to the inner wall of the connecting cylinder 44. A filter element 43 is bolted to the bottom of the connecting cover 41, and a rotating bar 42 is fixedly installed on the top of the connecting cylinder 44, which can directly perform connection and filtering operations.

[0036] When exhaust gas is discharged, the gas will be discharged into the filter element 43 through the exhaust pipe 24. After being filtered by the filter element 43, it will be directly discharged from the bottom end of the connecting tube 44 to the preset pipeline to achieve unified emission treatment. When removing it, the flange connection between the contact connecting cover 41 and the exhaust pipe 24 is rotated, and then the connecting tube 44 is directly removed and the connecting cover 41 is rotated through the turning bar 42, so that the connecting cover 41 is disengaged from the threaded connection state with the connecting tube 44, and finally it can be pulled upwards for replacement.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
