Description

Technical Field

[0001] This utility model relates to the field of industrial dust and smoke collectors, and in particular to a jet cleaning device for multi-tube dust collectors. Background Technology

[0002] Dust-laden fumes generated during industrial production processes can cause serious harm to the environment and human health, thus requiring purification treatment. Common methods include gravity settling chambers, inertial dust collectors, and cyclone dust collectors. Gravity settling chambers allow dust-laden fumes to flow slowly in a large space, causing the dust to settle to the bottom under gravity. Inertial dust collectors utilize the fact that when the airflow direction suddenly changes, the dust continues to move forward due to inertia and separates from the airflow. Cyclone dust collectors use the centrifugal force of the dust-laden fumes in the rotating airflow to throw the dust against the wall of the chamber and cause it to fall.

[0003] A cyclone separator is typically an inverted conical container, consisting of an inlet pipe, an outlet pipe, a cone, and a cylinder. The inlet pipe is usually connected tangentially to the cylinder, and the outlet pipe is located at the top center of the cyclone separator. The cone is the main body of the cyclone separator, with a dust discharge port at the bottom. Dust-laden flue gas enters the cyclone separator tangentially from the inlet pipe at a certain speed and rotates inside, forming a double swirling motion with the outer layer downward and the inner layer upward. Under the action of centrifugal force, dust particles are thrown against the outer wall of the cyclone separator and fall down the wall to the dust discharge port for discharge, while the purified gas moves upward from the inner layer and is discharged through the outlet pipe.

[0004] The traditional multi-tube dust collector jet cleaning device has the following drawbacks: during long-term operation, a large amount of dust easily accumulates in the cyclone and cone of the traditional multi-tube dust collector, resulting in a decrease in dust removal efficiency. In addition, the dust removal method often requires manual intervention, which is complicated and inefficient. Therefore, the multi-tube dust collector jet cleaning device is proposed to solve the above problems. Utility Model Content

A conical ash discharge port 68 is fixedly connected to the bottom outer wall of the dust collector shell 1. The conical ash discharge port 68 is located below the cyclones to collect the separated dust. A filter screen plate 69 is snapped onto the top inner wall of the dust collector shell 1.

[0025] Reference Figures 2-4 There are several horizontal pipes 65, which are fixedly connected to the outer right side of the hollow branch pipe 64. A support rod is fixedly connected to the right end of each horizontal pipe 65, and the support rod is fixedly connected to the outer front and rear sides of the dust collector housing 1. The hollow branch pipe 64 is connected to the mounting pipe 66, and an adjustable nozzle assembly is fixedly connected to the front end of the mounting pipe 66: 316L stainless steel nozzles with a logarithmic spiral distribution, a spray angle α = 15° ± 2°, and a dual-stage air path design: main air path pressure 0.6-0.8 MPa, and blowing air path pressure 0.4-0.6 MPa, asymmetrical. Pulse cleaning: 0.1s-level program control to avoid cyclone flow field disturbance. The mounting pipe 66 is connected to the inside of the cyclone body 67.

Support frames 5 are fixedly connected to both the left and right outer walls of the dust collector housing 1.

[0026] Reference Figures 3-4The auxiliary mechanism 7 includes a mounting groove 71, which is located on the top inner wall of the dust collector housing 1. A sealing plate 72 is snapped onto the top inner wall of the mounting groove 71 to seal the mounting groove 71. A lever 73 is slidably connected to the top inner wall of the sealing plate 72. A retaining plate is fixedly connected to the rear outer wall of the lever 73. A compression spring 74 is fixedly connected to the front outer wall of the lever 73 to generate a continuous pushing force on the lever 73.

The retaining plate is snapped onto the rear inner wall of the dust collector housing 1.

[0027] Working principle: During long-term dust removal operation, dust accumulates at the inlet of the cyclone sub-body 67. When the compressor body 61 is turned on, air is injected into the air tank body 62. The gas then enters the hollow branch pipe 64 through the through pipe 63. The gas then flows into multiple horizontal pipes 65. The gas in the multiple horizontal pipes 65 is ejected through multiple mounting pipes 66, which sprays away the dust at the inlet of the cyclone sub-body 67. The floating dust is then absorbed by the cyclone sub-body 67 and discharged below the conical ash discharge port 68. The filter screen 69 prevents unfiltered dust from flying out of the exhaust port 4. Since multiple cyclone sub-body 67s are in operation, they need to be inspected, maintained, or replaced regularly. By pulling the lever 73, the clamping plate moves and separates from the inner wall of the dust collector housing 1. Then, the sealing plate 72 is lifted and separated from the mounting groove 71, making it easier for personnel to maintain the internal cyclone sub-assemblies and filter screen 69.
