Description

Technical Field

[0001] This utility model relates to the field of waste gas purification technology, specifically a waste gas circulation device for tunnel kilns. Background Technology

[0002] Waste gas emission is a crucial aspect of tunnel kiln operation. Traditional waste gas treatment methods often involve directly releasing waste gas into the atmosphere, causing environmental pollution and wasting significant amounts of thermal energy. To improve energy efficiency and reduce environmental pollution, waste gas recirculation devices have emerged. However, existing waste gas recirculation devices have limited purification effects, failing to effectively remove harmful substances and particulate matter from the waste gas. This results in low-quality recirculated waste gas, impacting the tunnel kiln's production efficiency and product quality. Therefore, this paper proposes a waste gas recirculation device for tunnel kilns to address these issues. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 In this embodiment, a waste gas circulation device for a tunnel kiln includes a frame 1 and a purification box 2. The top of the purification box 2 is provided with an exhaust pipe 4, and an intake pipe 3 is fixedly connected to one side of the purification box 2. Both the exhaust pipe 4 and the intake pipe 3 are connected to the tunnel kiln. Waste gas is sent into the purification box 2 through a gas delivery device. The purification box 2 is provided with a first purification mechanism 5, and the top of the purification box 2 is fixedly connected with a second purification mechanism 6. A fixing mechanism 7 is provided at one end of the purification box 2.

[0024] The first purification mechanism 5 includes a pump body 501 fixedly connected to the pump body 501, an extraction pipe 502 fixedly connected to the bottom of the pump body 501, a spray pipe 503 set at the top of the pump body 501, and a drain pipe 8 fixedly connected to the bottom of the purification box 2. The first purification mechanism 5 sprays the purification liquid evenly into the exhaust gas through the pump body 501 and the spray pipe 503, effectively removing harmful gases and particulate matter from the exhaust gas.

[0025] The spray pipe 503 is fixedly connected inside the purification chamber 2 and is U-shaped. The U-shaped design of the spray pipe 503 ensures that the purification liquid can fully contact the exhaust gas, thereby improving the purification efficiency. One end of the spray pipe 503 is fixedly connected to a connecting end 504, which has a threaded connection hole inside. This allows the spray pipe 503 to be fixed inside the purification chamber 2, making it more stable during operation.

[0026] Secondly, the second purification mechanism 6 includes a housing 601 fixedly connected to the top of the purification chamber 2, an annular cover 602 fixedly connected inside the housing 601, a connecting box 604 fixedly connected to the top of the housing 601, and a filter plate 603 fixedly connected inside the connecting box 604.

[0027] Furthermore, the annular cover 602 is connected to the purification box 2, and a guide plate 606 is fixedly connected inside the annular cover 602. The arrangement of the annular cover 602 and the guide plate 606 allows the exhaust gas to be evenly distributed in the connecting box 604, avoiding the problem of insufficient local purification.

[0028] Furthermore, a movable door 607 is hinged to one end of the connecting box 604, and the air outlet pipe 4 is fixedly connected to the inside of the movable door 607. A handle 605 is fixedly connected to one end of the movable door 607. The movable door 607 and the connecting box 604 can be opened and closed by magnetic attraction or by a common door lock structure.

[0029] Additionally, the fixing mechanism 7 includes a cabinet door 701 hinged to one side of the purification chamber 2. A connector 702 is fixedly connected to the outer surface of the purification chamber 2. A bolt 703 is threaded to one end of the cabinet door 701, and the bolt 703 is threaded into the connector 702. Through the design of the cabinet door 701, connector 702, and bolt 703, the fixing mechanism 7 enables convenient opening and closing of the purification chamber 2, facilitating personnel to inspect, maintain, and replace the purification fluid inside the device. Furthermore, the drainage pipe 8 facilitates the discharge and treatment of the purification fluid, preventing equipment malfunctions caused by the accumulation of purification fluid.

[0030] The working principle of the above embodiments is as follows:

[0031] (1) The waste gas circulation device for tunnel kiln realizes multi-stage purification of waste gas by setting a first purification mechanism 5 and a second purification mechanism 6. The first purification mechanism 5 sprays the purification liquid evenly into the waste gas through the pump body 501 and the spray pipe 503, effectively removing harmful gases and particulate matter in the waste gas. The second purification mechanism 6 further filters out the tiny particulate matter in the waste gas through the filter plate 603 inside the connecting box 604, ensuring the quality of the recycled waste gas.

[0032] (2) The exhaust gas circulation device for tunnel kilns has a U-shaped spray pipe 503, which ensures that the purification liquid can fully contact the exhaust gas and improve the purification efficiency. The setting of the annular cover 602 and the guide plate 606 makes the exhaust gas evenly distributed in the connecting box 604, avoiding the problem of insufficient local purification. At the same time, the design of the movable door 607 and the handle 605 makes it easy to clean and maintain the inside of the connecting box 604, extending the service life of the device.
