Description

Technical Field

[0001] The utility model relates to the field of purification and treatment of printing and dyeing waste gas, and in particular to a purification and treatment device for printing and dyeing waste gas. Background Art

[0002] Printing and dyeing waste gas primarily originates from the volatilization of dyes and auxiliaries, as well as the drying process in setting machines. It contains large amounts of volatile organic compounds (VOCs), acidic gases, particulate matter, and malodorous gases. If these gases are discharged directly without treatment, they can have serious impacts on the environment and human health.

[0003] After searching, it was found that Chinese patent number CN 213853635 U discloses an environmentally friendly printing and dyeing waste gas purification and treatment device, which includes a purification device outer box and a sealing gasket. A base is provided at the bottom of the purification device outer box, and an exhaust gas inlet pipe is installed on the left side of the purification device outer box. A protective sleeve is provided on the outside of the exhaust gas inlet pipe. A sealing strip is provided at the front end of the purification device outer box, and a detachable front door is installed at the front end of the sealing strip. Bolts are provided inside the detachable front door. A jacket groove is provided at the top of the purification device outer box. The sealing gasket is provided above the jacket groove, and a clamping plate is installed above the sealing gasket. A filter element jacket is provided inside the jacket groove, and a filter element clamping slot is provided inside the filter element jacket. The utility model is provided with a fully enclosed structure between the exhaust gas inlet pipe and the protective sleeve, so that the exhaust gas inlet pipe can be protected by the protective sleeve to prevent the exhaust gas inlet pipe from being exposed to the air. The protective sleeve can effectively reduce the oxidation phenomenon of the exhaust gas inlet pipe.

[0004] However, the above-mentioned environmentally friendly printing and dyeing waste gas purification treatment device needs to be shut down when the filter element needs to be cleaned, resulting in the entire machine being unable to purify the printing and dyeing waste gas normally, thus having certain limitations.

[0005] Therefore, it is very necessary to invent a printing and dyeing waste gas purification treatment device. Utility Model Content

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] Example

[0022] Reference Figure 1-2 A printing and dyeing waste gas purification treatment device includes a main treatment tank 1, wherein: an air inlet pipe 2 is fixedly installed on one side of the main treatment tank 1, so that the printing and dyeing waste gas enters the main treatment tank 1 through the air inlet pipe 2 for purification treatment, and a plurality of air outlet pipes 3 are evenly fixedly installed on the other side of the main treatment tank 1, so that the purified printing and dyeing waste gas is discharged through the air outlet pipes 3, and the main treatment tank 1 is connected to the air inlet pipe 2 and the air outlet pipe 3;

[0023] It should be noted that the main processing tank 1 adopts the existing technology, such as the plasma purification equipment in the existing technology, the air inlet pipe 2 is connected to the air inlet of the plasma purification equipment, and the air outlet pipe 3 is connected to the air outlet of the plasma purification equipment;

[0024] A solenoid valve 4 and a filter cartridge 5 are fixedly installed on each outlet pipe 3, and the solenoid valve 4 is located between the filter cartridge 5 and the main treatment tank 1. The outlet pipe 3 is connected to the solenoid valve 4 and the filter cartridge 5, so that the solenoid valve 4 controls the on-off between the outlet pipe 3 and the treatment tank 1;

[0025] An activated carbon filter element 9 is detachably fixedly installed inside the filter cartridge 5 so that the printing and dyeing waste gas treated by the treatment tank 1 can be filtered for the second time through the activated carbon filter element 9, and a sealing cover 10 is fixedly installed on the outside of the opening of the filter cartridge 5 by bolts 12 so that the activated carbon filter element 9 can be disassembled, cleaned or replaced.

[0026] Two support platforms 6 are fixedly installed on each air outlet pipe 3, and the two support platforms 6 are evenly distributed on both sides of the corresponding filter cartridge 5. An internal threaded tube 7 is fixedly installed on the support platform 6; the sealing cover 10 is clamped with the internal threaded tube 7; the bolt 12 is threadedly fixedly connected to the internal threaded tube 7 to facilitate the disassembly and assembly of the sealing cover 10.

[0027] A pressure sensor 8 for detecting the disassembly of the sealing cover 10 is fixedly mounted on the internal threaded barrel 7. The pressure sensor 8 is electrically connected to the solenoid valve 4 through a controller.

[0028] Through the setting of the pressure sensor 8, if the electromagnetic valve 4 is forgotten to be closed during the process of replacing the activated carbon filter element 9, the sealing cover 10 will be loosened by simply removing the bolt 12, and the pressure value acting on the pressure sensor 8 will change, which will send an electrical signal to the controller, and the controller will activate the corresponding electromagnetic valve 4, making the electromagnetic valve 4 in the closed state, thereby preventing the leakage of printing and dyeing exhaust gas during the process of replacing the activated carbon filter element 9;

[0029] The controller adopts existing technology, such as the PLC controller in the existing technology, so it will not be described in detail here.

[0030] A fixing ear 11 is fixedly installed on each side of the sealing cover 10, and the fixing ear 11 is sleeved on the corresponding internal threaded tube 7 to facilitate positioning connection between the sealing cover 10 and the internal threaded tube 7 and ensure stability between the sealing cover 10 and the internal threaded tube 7. The fixing ear 11 is in extrusion contact with the pressure sensor 8.

[0031] Two extrusion columns 13 for applying pressure to the fixing ear 11 are fixedly installed on the nut of the bolt 12, and the extrusion columns 13 are evenly distributed on both sides of the stud, and the extrusion columns 13 are in extrusion contact with the fixing ear 11; after the sealing cover 10 is tightened by the bolt 12, the extrusion columns 13 will apply pressure to the fixing ear 11 and transmit the pressure to the pressure sensor 8, so that the pressure sensor 8 can monitor the sealing cover 10 to determine whether it is disassembled.

[0032] In this embodiment, when in use, the air inlet pipe 2 is connected to the exhaust gas outlet of the printing and dyeing equipment, and the air outlet pipe 3 can be connected to other external printing and dyeing exhaust gas treatment equipment for use;

[0033] When the printing and dyeing waste gas enters the main treatment tank 1 through the air inlet pipe 2, the main treatment tank 1 will treat the printing and dyeing waste gas. The treated waste gas will enter each outlet pipe 3 respectively, and will be filtered again by the activated carbon filter element 9 in the outlet pipe 3, and finally discharged through the outlet pipe 3;

[0034] When the activated carbon filter elements 9 in the outlet pipes 3 need to be cleaned and replaced one by one later, it is only necessary to close one of the corresponding solenoid valves 4 first, and the other outlet pipes 3 remain in normal operation;

[0035] Then remove the sealing cover 10. If you forget to close the corresponding solenoid valve 4 before removing the sealing cover 10, during the process of removing the bolt 12, as long as the pressure exerted by the sealing cover 10 on the pressure sensor 8 changes, the pressure sensor 8 will send a signal to the controller, which will activate the corresponding solenoid valve 4 through the controller, so that the corresponding solenoid valve 4 is in a closed state, thereby preventing accidental leakage of printing and dyeing waste gas; in this way, the overall process of cleaning and replacing the activated carbon filter element 9 is more convenient, safe and reliable.

[0036] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the scope of protection of the utility model.
