Description

Technical Field

[0001] The utility model relates to the technical field of flue gas purification, in particular to a tunnel kiln flue gas purification device. Background Art

[0002] Tunnel kiln flue gas purification is a critical issue that tunnel kiln manufacturers must address. It aims to reduce pollutant emissions from the flue gas and protect the environment and human health. The desulfurization tower is one type of tunnel kiln flue gas purification device.

[0003] Desulfurization towers usually use desulfurization liquid to spray the flue gas for desulfurization first, and then discharge the flue gas after passing through multiple filter layers. However, the nozzles used for spraying are fixedly installed, and the contact area between the spray liquid and the flue gas is limited, resulting in poor desulfurization effect. Therefore, a tunnel kiln flue gas purification device is proposed to solve the above problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides a tunnel kiln flue gas purification device with advantages such as dynamic spraying, which solves the problem of limited contact area between the spray liquid and the flue gas and poor desulfurization effect.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a tunnel kiln fume purification device, comprising a tower body, wherein the right end of the outer peripheral wall of the tower body is connected to an air inlet pipe, a mounting frame is fixedly installed inside the tower body and above the air inlet pipe, a plurality of nozzles are movably mounted on the top of the mounting frame, a connecting mechanism is provided on the mounting frame, a driving mechanism is provided on the left side of the tower body, and the top of the tower body is connected to an exhaust pipe;

[0006] The connecting mechanism includes a slide groove, a slider and a connecting frame. The top of the mounting frame is provided with a plurality of slide grooves. A slider is slidably mounted inside the slide groove. The nozzle is embedded in the slider. The plurality of sliders are fixedly connected by the connecting frame.

[0007] The driving mechanism includes a motor frame, a stepper motor, a driving gear, a connecting rod and an arc-shaped rack. A connecting rod with one end penetrating and extending to the left side of the tower body is fixedly installed on the left side of the outer peripheral wall of the connecting frame. An arc-shaped rack is fixedly installed on the left side of the connecting rod. The motor frame is fixedly installed on the left side of the outer peripheral wall of the tower body and below the arc-shaped rack. The stepper motor is fixedly installed on the top of the motor frame. The output end of the stepper motor is fixedly installed with a driving gear, and the driving gear is meshed with the arc-shaped rack.

[0008] Furthermore, a connecting hole is opened on the left side of the outer peripheral wall of the tower body, and the connecting hole matches the connecting rod. The front and back sides of the connecting rod are fixedly installed with an arc-shaped sealing plate with one end in contact with the outer wall of the tower body.

[0009] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

[0010] The tunnel kiln flue gas purification device, through the provided connecting mechanism and driving mechanism, can enable the nozzle to swing back and forth quickly on the mounting frame during desulfurization operation. This can significantly increase the contact area between the spray liquid and the flue gas, improve the desulfurization efficiency, and reduce the spray blind area.

[0011] The tunnel kiln fume purification device can always keep the connection hole in a sealed space by providing an arc-shaped sealing plate, thereby preventing fume from leaking from the connection hole and improving the practicability of the device. BRIEF DESCRIPTION OF THE DRAWINGS
