Environment-friendly energy-saving boiler equipment with filter device

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] like figure 1 As shown, the environmental protection and energy-saving boiler equipment with filter device according to the present invention includes a boiler body, and the boiler body includes a shell 1, the upper part of the shell 1 is provided with a heat conductor 2, and the bottom of the shell 1 is set There is a base 4, and the lower part of the left side of the housing 1 is provided with a smoke guide pipe 3; the smoke guide pipe 3 is connected to a filter device;

[0014] The filter device includes an L-shaped conduit 15, which is composed of a horizontal horizontal tube and a vertical vertical tube, the horizontal horizontal tube is connected with the smoke guide pipe 3, a primary filter screen 16 is arranged in the horizontal horizontal tube, and the vertical vertical tube The vertical pipe is provided with a secondary filter screen 12; the vertical vertical pipe of the L-shaped conduit 15 is inserted in the filter box 11; the middle part of the upper surface of the filter box 11 is provided with a through hole A, and the vertical vertical pipe of the L-shaped conduit 15 The joint with the through hole A is provided with a waterproof sealing ring A; the inner left side of the filter box 11 is provided with a stirring paddle 17, and the stirring paddle 17 is driven by a motor 10 arranged at the lower part of the left side of the filter box 11; A pump 6 is arranged at the bottom of the inner right side of the filter box 11, and a water pipe 5 is arranged on the pump nozzle of the pump 6, and the water pipe 5 is inserted through the through hole B at the lower part of the right side of the filter box 11 to be connected with the municipal water network; the filter box 11 is arranged on the lower frame type chassis 8, and the heating device 7 is arranged on the bottom surface of the horizontal part of the lower frame type chassis 8; a number of heating rods are arranged on the bottom surface of the filter box 11, and the bottom ends of the heating rods pass through The wire is connected to the heating device 7; the bottom of the left side of the filter box 11 is provided with a sewage pipe 9; the left side of the upper surface of the filter box 11 is provided with an exhaust pipe 13; the upper surface of the filter box 11 is provided with a T Shaped support frame 14, this T-shaped support frame 14 is connected with L-shaped conduit 15.

[0015] As a preference of the present invention, a feeding port is provided on the right side of the upper surface of the filter box 11, and a plug is provided on the feeding port.

[0016] As a preference of the present invention, a thermal insulation layer is provided on the inner wall of the filter box 11 .

[0017] In the present invention, when the tail gas discharged from the boiler is discharged from the smoke guide pipe 3 to the filter device, when the dust-containing flue gas passes through the L-shaped conduit 15, it is arranged on the first-stage filter screen 16 in the horizontal horizontal pipe to perform the first step. Once filtered; then through the secondary filter screen 12 in its vertical vertical pipe, a secondary filter is carried out; the meshes of the primary filter screen 16 and the secondary filter screen 12 are circular in this design, and the diameters of the meshes are different , can intercept dust particles of different sizes; guide the secondary filtered flue gas into the filter box 11, the filter box 11 is provided with tap water, and the height of the tap water injection is not more than half of the height of the filter box 11, at this time start The heating device 7 controls the heating of the heating rod to make the tap water in the filter box 11 boil. In order to further intensify the boiling and form turbulent flow, the control motor drives the stirring paddle 17 to stir the boiling water in the filter box, thereby further filtering the flue gas. The remaining dust particles will finally be discharged to the outside through the exhaust pipe 13 through the gas that has been filtered and purified three times. At this time, the gas is a qualified exhaust gas, which is environmentally friendly and energy-saving.

[0018] The environmental protection and energy-saving boiler equipment with filtering device described in the present invention adopts multi-stage filtering device to remove harmful particles such as dust in boiler exhaust gas. It has simple structure, low cost, convenient operation and multi-stage filtering. The purification effect is good, environmental protection and energy saving, will not pollute the air, and meet the national environmental protection exhaust standards and other advantages.

[0019] The above is only a preferred embodiment of the present invention, so all equivalent changes or modifications made according to the structure, features and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
