Technical Field
[0001] The utility model relates to the technical field of boilers, in particular to a boiler flue gas dust removal device. Background Art
[0002] A boiler is an energy conversion device. The energy input into the boiler is in the form of chemical energy in the fuel, electrical energy, thermal energy of high-temperature flue gas, etc. After conversion by the boiler, steam, high-temperature water or organic heat carrier with a certain amount of thermal energy is output to the outside.
[0003] However, when existing boilers are in use, a large amount of smoke and dust generated will be continuously discharged into the outside air during production, causing the surrounding air environment to deteriorate sharply. Because the dust generated by boiler combustion cannot be effectively treated, the boiler has a poor environmental protection effect. In addition to dust, the smoke and dust also contains a large amount of waste gas, which brings great pollution to the environment. Utility Model Content
[0004] The utility model aims to address the deficiencies in the prior art and propose a boiler flue gas dust removal device to solve the technical problem that a large amount of smoke is continuously discharged into the outside air during production, causing the surrounding air environment to deteriorate sharply because the dust generated by boiler combustion cannot be effectively treated, resulting in the boiler having a poor environmental protection effect.
[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a boiler flue gas dust removal device comprises a workbench, a funnel-type dust removal box is embedded on the workbench, an arc-shaped dividing plate is arranged on the inner wall of the dust removal box, the dividing plate divides the dust removal box into an upper dust removal chamber and a lower dust removal chamber, a first dust removal assembly is arranged at the bottom of the dust removal box, the first dust removal assembly comprises a first conducting pipe with an internal thread at one end of the inner wall, a filter plate and an activated carbon bag with a cavity structure, an external thread is arranged on the outer wall of the funnel at the bottom of the dust removal box, the first conducting pipe is threadedly sleeved at the bottom of the dust removal box, the filter plate is arranged in the first conducting pipe, the activated carbon bag is arranged in the filter plate, an electric telescopic rod is arranged at the bottom of the workbench, a support plate is arranged at the telescopic end of the electric telescopic rod, a first motor is arranged on the support plate, an elongated through slot is arranged on the workbench, a first rotating shaft which is vertically upward and passes through the elongated through slot is fixedly arranged on the output end of the first motor, and two second dust removal assemblies which can rotate into the lower dust removal chamber are fixedly arranged on the first rotating shaft.
[0006] Working principle:
[0007] When it is necessary to effectively remove dust from the flue gas generated by the boiler, first, the flue gas in the boiler will enter the dust removal box along the first conducting pipe. First, the gas containing smoke will pass through the first layer of the filter plate and the activated carbon bag for filtration, and as the smoke rises, it will enter the lower dust removal chamber in the dust removal box. The smoke will then pass through the second dust removal assembly, and finally pass through the partition plate and then enter the first dust removal chamber. When the second dust removal assembly filters most of the particulate matter in the smoke, it is easy to cause blockage in the second dust removal assembly. At this time, the operator starts the electric telescopic rod, and the telescopic end of the electric telescopic rod drives the support plate to move, and the support plate drives the first motor to move. When one of the second dust removal assemblies is moved out of the dust removal box, then, the operator starts the first motor, and the first motor drives the first rotating shaft to rotate, the first rotating shaft drives the rotating disk to rotate, and the rotating disk drives the dust removal assembly to rotate, and cleans one of the second dust removal assemblies that has been blocked, thereby effectively increasing the filtration of smoke in the boiler.
[0008] The beneficial effects of the utility model are:
[0009] Compared with the existing technology, the present application document can further increase the effect of treating smoke in the dust removal box by timely cleaning or replacing the second dust removal component, and can also effectively isolate the smoke generated in the boiler to prevent the environment from being polluted due to the excessive amount of dust in the boiler smoke.
