Abstract
Description
Technical Field
[0001] This utility model relates to the field of stenter technology, specifically to an integrated treatment device for the circulation and purification of waste gas from stenters. Background Technology
[0002] The stenter is one of the main pieces of equipment in the textile dyeing and finishing industry. During its production process, it emits a large amount of organic waste gas, polluting the air. For example, CN221933507U, "Waste Gas Treatment Device for Stenter," describes a device that includes a treatment box connected to an inlet pipe, an outlet pipe, and a spray assembly. A filter plate is connected inside the treatment box, and a connection port is located at one end of the box. A sealing block is connected to the treatment box, used to open and close the connection port. The sealing block is detachably connected to the connection port via a locking assembly. The filter plate slides along its length between the treatment box and the connection port. When oil fumes and impurities adhere to the surface of the filter plate, the sealing block is removed from the connection port, and the filter plate is moved along the length of the treatment box, allowing it to return to its original position within the treatment box, thus facilitating cleaning. However, this method only focuses on cleaning the filter plate and relies solely on sequential filtration, resulting in a very limited filtration effect.
[0003] This case arose in order to resolve the aforementioned issues. Summary of the Invention

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0017] This utility model embodiment provides an integrated treatment device for the circulation and purification of exhaust gas from a stenter, such as... Figure 1-2 As shown, the system includes a treatment box 1, on which a purification cover 2 is provided. The purification cover 2 includes a cover surface 3, an outer tube 4, and an inner tube 5. The outer tube 4 is disposed on the cover surface, and the inner tube 5 is disposed inside the outer tube 4. A support column 11 is provided between the upper end of the inner tube 5 and the upper inner side of the outer tube 4, and the upper end of the support column 11 is fixed to the upper end of the outer tube 4. An air outlet pipe 6 is connected to the upper end of the outer tube 4, and the air outlet pipe 6 communicates with the inner tube 5. A filter screen 7 is provided between the upper end of the inner tube 5 and the lower outer side of the air outlet pipe 6. An air inlet pipe 8 is provided on the outer side of the outer tube 4.
[0018] The filter screen 7 is held between the support column 11 and the inner tube 5. When the filter screen needs to be replaced, first separate the cover 3 from the processing box 1. At this time, the inner tube 5 and the filter screen 7 at the upper end of the inner tube 5 remain in the processing box 1. Remove the old filter screen and place the new filter screen on top of the inner tube 5. Figure 2 As can be seen, the filter screen 7 is ring-shaped, and there are annular grooves on the top and bottom for the support column 11 and the upper end of the inner tube 5 to engage.
[0019] Reference Appendix Figure 2 The lower end of the inner tube 5 abuts against the bottom surface of the processing box 1. A vent 51 is provided on the outer side of the lower end of the inner tube 5. Inside the inner tube 5, near the lower end, there is a fan blade 52 and a motor 53 that drives the fan blade 52. When the fan blade 52 rotates, it drives the gas from bottom to top. When the solenoid valve on the outlet pipe 6 is closed, the gas in the device rises from the inner tube 5 and falls in the outer tube 4, circulating through the filter screen 7 to complete multiple filtrations.
[0020] It should be noted that an exhaust gas detection mechanism 12 is connected to the exhaust pipe 6. The exhaust gas detection mechanism is equipped with a solenoid valve. The solenoid valve and the exhaust gas detection mechanism 12 are electrically connected. The solenoid valve will only open the exhaust pipe 6 when the exhaust gas detection mechanism detects that the gas passing through meets the emission standards. The opening and closing of the exhaust pipe 6 is controlled by the solenoid valve. The opening and closing of the intake pipe 8 is also controlled by a solenoid valve (not shown in the figure). The solenoid valves on the intake pipe 8 and the exhaust pipe are both controlled by the exhaust gas detection mechanism 12 and are in the same state (when one is open, the other is also open, and when one is closed, the other is also closed).
[0021] Reference Appendix Figure 2 A water tank 9 is provided on the cover 3, and the water tank 9 is located around the outer pipe 4. A nozzle 10 is provided on the bottom surface of the cover 3. The nozzle 10 is connected to the water tank 9. A water inlet pipe is provided on the water tank 9. The nozzle 10 causes the gas in the treatment box 1 to settle and flow out from the drain pipe at the bottom of the treatment box 1 (not shown in the figure, the drain pipe is directly connected to the bottom of the treatment box 1 and a valve is provided on the drain pipe). The drain pipe is opened at intervals, and the air intake is stopped when it is opened.
[0022] A sealing gasket is provided at the bottom edge of the cover 3 to ensure the airtightness of the device. The cover 3 is fastened to the upper end of the treatment box 1 with bolts. During use, the valve on the air inlet pipe 8 is opened to allow exhaust gas to enter. The exhaust gas displaces the air in the original device. Since the air in the original device meets the emission standards, it can pass the exhaust gas test. The exhaust pipe 6 is in the open state. When the original air is exhausted and the exhaust gas is found to be unqualified, the solenoid valve closes. After the operator observes that the solenoid valve is closed, the motor 53 should be turned on to circulate and filter the gas inside. The solenoid valve is indicated by an indicator light (not shown in the figure), and the motor 53 switch (not shown) is located at the upper end of the outer pipe 4. The parts not shown in the figure are simple existing structures and technologies, so they will not be described in detail.
[0023] This utility model discloses an integrated treatment device for the circulation and purification of exhaust gas from a stenter. By setting up inner and outer pipes and a treatment box, the exhaust gas enters the outer pipe and circulates between the treatment box and the inner and outer pipes under the action of a fan. It is filtered by a filter screen until the exhaust gas passes the test by the exhaust gas detection mechanism. Then, the exhaust pipe is opened by a solenoid valve to exhaust the gas. Through circulation filtration, the filtration effect is increased, and there is no need to set up multiple filter boxes, which saves costs.
[0024] Although 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 can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
