[0033] The utility model provides a purification and recovery device.

[0034] In the prior art, the pre-treatment measures for paint mist in industry mainly include adding multi-stage water washing towers to reduce the concentration of paint mist. However, multi-stage water washing towers occupy a large area and are expensive. In addition, the intercepted paint mist needs to be separated into solid and liquid with flocculants, and then the separated paint residue is treated as hazardous waste. Since the fillers are blocked by paint residues during the operation of the water washing tower, it is necessary to frequently replace the fillers and add agents. The actual operation is complicated and the operating cost is high. The subsequent paint mist terminal treatment facilities cannot operate normally, mainly manifested as: the light tubes of paint mist treatment equipment such as low-temperature plasma and photocatalytic oxidation often cause fires or even explosions due to blockage; the catalytic burner will block the honeycomb ceramic catalyst; the activated carbon adsorption box will block the activated carbon pores, causing the activated carbon to deactivate rapidly, generating a large amount of hazardous waste and increasing a large amount of hazardous waste disposal costs.

[0035] In order to solve the above technical problems, the technical solution of the utility model is to set a purification channel in the cavity of the purification box, and the air inlet and air outlet of the purification channel are opened on the two side walls of the purification box, and the wind power component is set at the air outlet and is used to generate suction force, so that the target gas enters the purification channel from the air inlet, and after passing through the mesh disk of the first purification component in the purification channel, the driving member drives the mesh disk to rotate, so that the paint mist contained in the target gas adheres to the mesh disk, which has a purification effect, and then the target gas forms the first purified gas. Under the action of the suction force, the first purified gas is discharged from the air outlet, thereby achieving the purification of the target gas. At the same time, the paint mist continuously adheres to the mesh disk to form an aggregate, and the driving member drives the mesh disk to rotate, so that the aggregate leaves the mesh disk and is recovered by the recovery device, which can also save costs. Compared with the prior art method of reducing the paint mist concentration through a multi-stage water washing tower for purification, the present technical solution does not require replacement of fillers, addition of reagents, etc. The present technical solution generates suction force through a wind power component, so that when the target gas passes through the mesh disk, the paint mist adheres to the mesh disk, thereby achieving the purpose of purification. The operating cost is low, and the paint mist can be recycled and reused, further reducing the cost.

[0036] The above technical solution is described in detail below with reference to the accompanying drawings.

[0037] In the embodiment of the present utility model, Figure 1-Figure 3As shown, the purification and recovery equipment is used for purifying the target gas, the target gas contains paint mist, and the purification and recovery equipment comprises: a purification box 100, a wind power component 200, a first purification component 300 and a recovery device; wherein the purification box 100 is provided with a cavity, a purification channel is formed in the cavity, and the air inlet 110 and the air outlet 120 of the purification channel are respectively arranged on the two side walls of the cavity; the wind power component 200 is arranged at the air outlet 120, and is used to generate a suction force, so that the target gas enters the purification channel from the air inlet 110 and exits from the air outlet 120. The paint mist is discharged from the air outlet 120; the first purification component 300 includes a driving member 320 and at least one mesh disk 310, the mesh disk 310 is arranged in the purification channel and is arranged opposite to the air inlet 110. When the target gas passes through the purification channel, the driving member 320 drives the mesh disk 310 to rotate so that the paint mist adheres to the mesh disk 310 and aggregates to form an aggregate, and the target gas forms a first purified gas. The rotation of the mesh disk 310 also causes the aggregate to leave the mesh disk 310 under the action of centrifugal force; a recovery device 400, the recovery device 400 is used to collect the aggregate.

[0038] It can be understood that there is a gap on the net disk 310, so that under the action of the suction force of the wind power component 200, an airflow is formed from the air outlet 120, the purification channel and the air outlet 120, so that the target gas can enter the purification channel from the air inlet 110. In the specific implementation process, the net disk 310 is intercepted in the purification channel, and one surface of the net disk 310 is arranged toward the air inlet 110, so that the paint mist entering the purification channel is discharged from the air outlet 120 after being intercepted and filtered by the net disk 310. Among them, the wind power component 200 can be a fan, a suction pump, etc., which is not limited in this embodiment. This embodiment uses the principle of "high-speed dynamic interception" to intercept paint mist. Compared with traditional static filtering devices and structures, this embodiment can set the rotation speed according to actual working conditions to effectively intercept paint mist.

[0039] In addition, the purification and recovery device 400 provided in this embodiment is also suitable for purifying the paint mist generated during the dry painting process. The paint mist also continuously adheres to the mesh disk 310 and forms an irregular block structure. The rotation of the mesh disk 310 causes the block structure to leave the mesh disk 310 under the action of centrifugal force. It can be understood that, depending on the type of paint spraying, the assembly can be solid paint spraying and liquid paint spraying. Therefore, the purification and recovery equipment provided in this embodiment is not limited by the viscosity of the paint mist to be processed, and both dry paint mist and wet paint mist can be processed.

[0040] The driving member 320 drives the net disk 310 to rotate at a high speed, and the paint mist adheres to the net disk 310. Under the action of centrifugal force, the attached aggregate on the net disk 310 is also thrown out and leaves the net disk 310, and is recovered by the recovery device 400. The driving member 320 is a motor. Further, the driving member 320 is connected to the rotating shaft 330, the net disk 310 is connected to the rotating shaft 330, and the air outlet 120 is provided with a fixing plate 150, one end of the rotating shaft 330 is connected to the fixing plate 150, and the other end is connected to the side wall of the purification box 100.

[0041] In the specific implementation process, the fixing plate 150 is connected across the air outlet 120, and the fixing plate 150 is connected to a fixing block by screws or welding on the side facing the cavity, and the rotating shaft 330 is rotatably connected to the fixing block through a bearing. Further, the purification box is also provided with a driving cavity 160, and the other end of the rotating shaft 330 extends into the driving cavity 160 and is connected to a driving disk 340, and the driving member 320 is a motor, which is drivingly connected to the driving disk 340 and drives the driving disk 340 to rotate.

[0042] In the specific implementation process, the motor is fixed at the bottom of the purification box 100, the drive chamber 160 is located in the purification box 100 and at one end away from the air inlet 110, and the drive chamber 160 is sealed with the purification chamber to protect the drive disk 340 and other structures in the drive chamber 160. Specifically, the motor is connected to a driving wheel, which can extend into the drive chamber 160 through a belt or chain, and drive the drive disk 340, and then drive the rotating shaft 330 to rotate through the drive disk 340, thereby realizing the rotation of the net disk 310. It can be understood that the net disk 310 can be fixed on the rotating shaft 330 by a structure such as a fixing pin. In addition, the side wall of the drive chamber 160 away from the cavity is provided with a second door body, and the drive disk 340 and other structures can be easily repaired and replaced by opening the second door body.

[0043] Optionally, a mounting plate 130 is provided in the cavity, the mounting plate 130 is connected to a mesh cover 140 , the mesh cover 140 is arranged around the mesh disk 310 , and the mesh disk 310 rotates so that the aggregate enters the mesh cover 140 .

[0044] In the present embodiment, the edge of the mounting plate 130 is connected to the inner wall of the cavity, such as by fixing with a screw or other connecting piece, which is not limited in the present embodiment. The mounting plate 130 is provided with a through hole so that the target gas can pass through, and the mesh disk 310 is located at the through hole for intercepting the target gas. The mesh disk 310 rotates and makes the paint mist in the target gas adhere to the mesh disk 310, thereby achieving the purification of the target gas, so that the target is purified by the mesh disk 310 to form a first purified gas, and the first purified gas is discharged from the purification channel from the air outlet 120. It can be understood that the rotation of the mesh disk 310 will also generate centrifugal force, so that the aggregate on the mesh disk 310 is thrown off and enters the cavity. In the present embodiment, the mesh cover 140 is fixed on the mounting plate 130, and the mesh cover 140 surrounds the mesh disk 310, so that the aggregate thrown off by the mesh disk 310 enters the mesh cover 140 and flows along the mesh cover 140 to the recovery device 400.

[0045] Furthermore, the bottom of the mesh cover 140 is provided with an opening, and the aggregate is discharged from the opening. The mesh cover 140 can also play a role in drainage and guidance. In the specific implementation process, the recovery device 400 is located at the bottom of the purification box 100, and the aggregate flows out from the opening and falls into the recovery device 400.

[0046] Optionally, the purification channel is provided with a plurality of spaced mesh disks 310, and the distance between adjacent mesh disks 310 is at least 160 mm. In this embodiment, taking three spaced mesh disks 310 arranged in the purification channel as an example, it can be understood that the inner wall of the cavity is respectively connected with the mounting plate 130 and the mesh cover 140 corresponding to the mesh disk 310.

[0047] In this embodiment, three mesh disks 310 are used to perform three-stage interception and purification on the target gas to improve the purification effect. The multi-stage interception mesh disk 310 is more efficient than the single-stage interception, and the number of interception mesh disks 310 can be increased or decreased according to actual working conditions.

[0048] In the specific implementation process, the speed of the interception network disk can be adjusted according to the actual situation to achieve different treatment effects. According to the fluid simulation results of the purification and recovery equipment for paint mist purification, it can be known that the interception efficiency of the interception network disk at different speeds is different, and the efficiency increases with the increase of speed; and the 1st and 2nd level network disks play the main interception role, and the interception efficiency of the 1st and 2nd level network disks increases with time. The three-level interception network disk can achieve a comprehensive interception efficiency of 50.6% for paint mist.

[0049] Compared with the multi-stage spray tower device currently used in industry, the advantages of this equipment are as follows:

[0050]

[0051] The simulation medium is UV paint, with a density of 1.13g / ml and a viscosity of 500-700mPas. Figure 4The simulation results are shown in the following two tables;

[0052] Among them, the air volume generated by the fan component is 2000m3 / h, and the speed of the network disk is 2000rpm. The interception and purification efficiency of paint mist is as follows:

[0053]

[0054] The air volume generated by the fan assembly is 2000m3 / h. When the speed of the network disk is 1500rpm, the interception and purification efficiency of paint mist is as follows:

[0055]

[0056] Specifically, the simulation results are all after the equipment runs for 1 hour. It can be clearly seen from the above that the interception efficiency of the three-level baffles is quite different. The efficiency of the first-level net disk is about 17.6%, the second-level net disk is about 16.8%, and the third-level net disk is about 16.2%. The efficiency decreases step by step, and each efficiency value changes with time. It is inevitable that the interception and purification efficiency decreases. The first-level baffle will block large particles of UV paint mist. Small particles of UV paint mist pass through the mesh gap of the net disk or are sheared into small particles and then enter the net disk of the same density, so the interception effect becomes worse. In addition, as time goes by, the wind resistance inside the equipment becomes larger. This is because the paint mist on the net disk 310 aggregates and blocks the air duct. The outer ring of the net disk 310 has a large linear speed and a large centrifugal force, so the paint mist aggregates more. The net disk 310 close to the central axis will also aggregate more paint mist due to the narrow gap flow channel. Therefore, the net disk 310 needs to be checked and cleaned regularly when in use. In addition, a first door body is provided on one side wall of the cavity, and structures such as the mesh cover and the mesh disk can be easily inspected and replaced by opening the first door body.

[0057] Optionally, the recovery device 400 includes a collection tank 410 , which is disposed at the bottom of the purification box 100 and communicated with the purification channel, and the aggregate enters the collection tank 410 from the purification channel.

[0058] In the specific implementation process, the purification box 100 is connected to a bracket, which lifts the purification box 100 to a certain height, and a universal wheel is also provided at the bottom of the bracket to facilitate the movement of the entire device. In this embodiment, a recovery port is provided at the bottom of the purification box 100, and the collection tank 410 is located at the recovery port, so that the collection tank 410 is connected to the cavity, and the collection body falls from the cavity into the collection tank 410 to achieve recovery. The collection tank 410 is set in a conical shape to facilitate the collection of the collection body. In this way, the entire purification and recovery equipment is small in size and relatively low in cost, and can also recycle paint to reduce paint mist emissions.

[0059] In addition, in this embodiment, it should be noted that in order to prevent the target gas from flowing from the collection tank 410 to the air outlet 120, the bottom of the mounting plate 130 also extends into the collection tank 410, so that the target gas flows through the mesh disk 310 to the air outlet 120, thereby improving the purification effect.

[0060] Furthermore, the recovery device 400 also includes a recovery pipe 420, which is connected to the collection tank 410. The recovery pipe 420 is provided with a pressure sensor and a delivery pump. The pressure sensor is communicatively connected with the delivery pump, and the delivery pump is used to transport the aggregate.

[0061] In the specific implementation process, the recovery pipe 420 is also provided with a valve for controlling the on and off of the recovery pipe 420. The pressure sensor is used to sense the pressure applied by the assembly. When the value of the pressure sensor exceeds 80, the pressure sensor generates a first control signal and transmits the first control signal to the delivery pump. The delivery pump is turned on and delivers the assembly. It can be understood that the delivery pump is suitable for the case where the assembly is a paint liquid. When the value of the pressure sensor is lower than 15, the pressure sensor generates a second control signal and transmits the second control signal to the delivery pump. The delivery pump is turned off and stops delivery. In practice, the delivery pump adopts an electromagnetic diaphragm pump.

[0062] Optionally, the purification and recovery equipment further includes a second purification component 500 , which is disposed between the air outlet 120 and the wind power component 200 , and the first purified gas passes through the second purification component 500 to form a second purified gas.

[0063] In the specific implementation process, after the target gas passes through the first purification component 300, the paint mist contained in it is intercepted and purified to form a first purified gas. However, there may still be finer paint mist particles in the first purified gas. In this way, the first purified gas passes through the second purification component 500 to further purify the first purified gas, so that the first purified gas forms a second purified gas, further improving the purification effect. The second purified gas is discharged after passing through the wind power component 200 to ensure the purification effect.

[0064] Furthermore, the second purification component 500 includes a fixing box 510 and a filter 520 . The filter 520 is arranged opposite to the air outlet 120 and is used to filter the first purified gas. The filter 520 is accommodated in the fixing box 510 , and the filter 520 is slidably connected to the fixing box 510 .

[0065] In the specific implementation process, the fixed box 510 is located at the air outlet 120, and a receiving chamber is arranged inside the fixed box 510, and the filter 520 is accommodated in the receiving chamber. An entrance is provided at the bottom of the fixed box 510, so that the receiving chamber inside the fixed box 510 is connected to the air outlet 120, so that the first purified gas enters the receiving chamber. The first purified gas passes through the filter 520, and an outlet is provided at the top of the fixed box 510. The first purified gas passes through the filter 520 and is discharged from the outlet to the wind power component 200. The wind power component 200 is also connected to an air outlet pipe, and the second purified gas is discharged into the atmosphere after being transported to the next process from the air outlet pipe. The filter 520 is slidably connected to the fixed box 510, and the filter 520 can be pulled out of the fixed box 510 by pulling the filter 520, which is convenient for replacement. In addition, it can be understood that a third door body is provided on one side of the fixed box 510, the third door body is opened, and then the filter 520 is pulled out to replace and clean, and maintenance and cleaning are convenient.

[0066] The purification and recovery equipment provided by the technical solution of the utility model, the target gas containing paint mist enters the equipment, passes through the three-stage high-speed rotating interception mesh disk 310, so that the paint mist adheres to the mesh disk 310 to form an aggregate, such as paint liquid, etc., under the centrifugal state, the paint liquid is thrown into the surrounding mesh cover 140, and through the action of gravity, it flows into the conical collection tank 410 below, and is controlled to open and close by the electromagnetic diaphragm pump through the pressure sensor to transport the paint liquid to the designated recovery device 400. After passing through the high-speed dynamic interception mesh disk 310, the target gas is effectively purified to form the first purified gas, and a very small part of the paint mist in the first purified gas is adsorbed again by the interception filter screen of the air outlet 120 to form the second purified gas, and finally, the second purified gas is introduced into the main air duct through the variable frequency fan.

[0067] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention.
