Description

Technical Field

[0001] This utility model relates to the field of dry desulfurization tower technology, specifically to a Venturi adjustable mechanism for a dry desulfurization tower in a refractory kiln. Background Technology

[0002] Dry desulfurization towers are the core devices in flue gas treatment systems for industrial equipment such as kilns and boilers. Their main function is to remove sulfides from flue gas through dry processes, while also having a certain dust removal effect, ultimately achieving compliant emissions. In order to adjust the reaction efficiency between flue gas and desulfurizing agent, a refractory material venturi adjustable mechanism is needed for dry desulfurization towers in kilns.

[0003] In the traditional dry desulfurization tower for refractory kilns, the Venturi adjustable mechanism is used. In the environmental protection equipment for kiln flue gas treatment, the dry desulfurization tower is equipped with a Venturi accelerator near the bottom to suddenly increase the flue gas flow rate, which facilitates the formation of air turbulence in the desulfurization tower. However, the traditional device is difficult to adjust the flue gas flow rate according to the amount of flue gas, which affects the reaction efficiency between the flue gas and the desulfurizing agent. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a Venturi adjustable mechanism for dry desulfurization towers in refractory kilns, thereby solving the problems mentioned in the background section.

[0005] This utility model provides the following technical solution: a Venturi adjustable mechanism for a dry desulfurization tower in a refractory kiln, comprising a Venturi tube, a fixed frame fixedly mounted on the inner wall of the Venturi tube, a baffle plate slidably connected to the inner wall of the fixed frame, a baffle plate slidably connected to the side of the baffle plate slidably connected to the inner wall of the fixed frame, toothed plates fixedly mounted on the top of both the baffle plate slidably, a rotating gear rotatably connected to the top of the inner wall of the fixed frame, and the convex teeth of the rotating gear meshing with the convex teeth on the sides of the two toothed plates, an outer cylinder fixedly mounted on the side of the fixed frame, a sliding cylinder slidably sleeved on the inner wall of the outer cylinder, a side plate fixedly mounted on the side of the sliding cylinder, and the inner wall of the side plate fixedly sleeved to the outer edge of the Venturi tube, dustproof telescopic plates fixedly mounted on both sides of the baffle plate slidably, and the ends of the dustproof telescopic plates away from the sides of the baffle plate slidably mounted to the inner wall of the fixed frame.

[0006] As a preferred embodiment of this utility model, an auxiliary plate is fixedly mounted on the top of the fixed frame, an electric telescopic rod is fixedly mounted on the side of the auxiliary plate, a toothed block is fixedly mounted on the output end of the electric telescopic rod, and a positioning gear is engaged by the toothed blocks on the side of the toothed blocks. The bottom of the positioning gear is fixedly mounted on the top of the rotating gear.

[0007] As a preferred embodiment of this utility model, an L-shaped plate is fixedly mounted on the top of the fixed frame, and a rotating motor is fixedly mounted on the top of the L-shaped plate. The output shaft of the rotating motor is fixedly sleeved with the inner wall of the positioning gear.

[0008] As a preferred embodiment of this utility model, a sliding rod is fixedly sleeved on the inner wall of the sliding cylinder, an inner cylinder is slidably sleeved on the outer edge of the sliding rod, and the outer edge of the inner cylinder is slidably sleeved with the inner wall of the sliding cylinder. The side of the inner cylinder is fixedly assembled with the inner wall of the outer cylinder. A coil is fixedly sleeved on the inner wall of the outer cylinder. A magnet ring is fixedly assembled on the side of the sliding cylinder, and the outer edge of the magnet ring is slidably sleeved with the inner wall of the coil.

[0009] As a preferred embodiment of this utility model, a spring is fixedly connected to the side of the outer cylinder, and the end of the spring away from the outer cylinder is fixedly connected to the side of the side plate.

[0010] As a preferred embodiment of this utility model, a flue gas flow meter is fixedly sleeved on the inner wall of the venturi tube, and a PLC controller is fixedly mounted on the top of the fixed frame. The PLC controller is electrically connected to the flue gas flow meter, the electric telescopic rod, and the rotating motor.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. The adjustable Venturi mechanism of the dry desulfurization tower for refractory kilns utilizes the cooperation of baffle one and baffle two. A flue gas flow meter detects the amount of flue gas inside the Venturi tube. A PLC controller then controls an electric telescopic rod to separate the toothed block from the positioning gear. A rotating motor then drives the rotating gear through the positioning gear, which in turn drives baffle one and baffle two to move in opposite directions via a toothed plate. This helps adjust the gap between the inner walls of baffle one and baffle two, facilitating the adjustment of the flue gas flow rate according to the flue gas volume. This improves the reaction efficiency between the flue gas and the desulfurizing agent, saves material usage, and ultimately better achieves the data standards for dry desulfurization.

[0012] 2. The Venturi adjustable mechanism of the dry desulfurization tower for refractory kilns utilizes the cooperation of a sliding cylinder and an outer cylinder. When baffle one and baffle two are adjusted and operated, gas flows through the inner walls of baffle one and baffle two. Then, the outer edge of the sliding rod slides on the inner wall of the inner cylinder, the outer edge of the sliding cylinder slides on the inner wall of the outer cylinder, and the inner wall of the sliding cylinder slides on the outer edge of the inner cylinder. This, in turn, drives the magnetic ring to slide on the inner wall of the coil. The coil then generates electromagnetic damping on the magnetic ring, thereby assisting in vibration reduction and ensuring the stable installation of baffle one and baffle two. This, in turn, helps to stabilize the flow of flue gas after the flue gas volume is adjusted. Attached Figure Description
