Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a boiler room flue gas dust removal desulphurization unit, including advancing mouth 1, it has two filters 5 that carry out filterable to the dust in the flue gas to advance 1 rear of mouth through pipeline 3 connection, two filters 5 can change the use in turn through the control of first valve 2, there are two desulfurizing towers 7 that carry out the desulfurization after filtering and further filterable filter 5 rear through pipeline 3 intercommunication, two desulfurizing towers 7 change the use in turn through the rotation control of second valve 6, two 7 rear of desulfurizing towers are provided with and carry out exhaust smoke vent 9 with the flue gas after the dust removal filtration.

Flue gas enters from a smoke inlet 1, the flue gas enters an upper filter 5 through an upper pipeline 3 by rotating a first valve 2, when the flue gas passes through a plurality of layers of first filter layers 4, dust in the flue gas is filtered by the first filter layers 4, then the filtered flue gas enters an upper desulfurizing tower 7 through the upper pipeline 3 by rotating a second valve 6, the desulfurizing tower 7 desulfurizes the flue gas and then enters a smoke outlet 9 through the pipeline 3 to be discharged, when dirt in the upper filter 5 is excessive, the flue gas enters a lower filter 5 through a lower pipeline 3 by rotating the first valve 2, then the upper filter 5 can be cleaned while the device works, when the inner part of the upper desulfurizing tower 7 needs to be cleaned, the filtered flue gas enters the lower desulfurizing tower 7 through the lower pipeline 3 to be desulfurized by rotating the second valve 6, at the same time, the upper desulfurizing tower 7 can be cleaned.

The rear of the smoke inlet 1 is provided with a first valve 2, the pipeline 3 is branched into two pipelines 3, the middle of each branched pipeline 3 is fixedly connected with a filter 5, a plurality of layers of first filtering layers 4 are arranged in the filters 5, and an ash hopper 12 is detachably connected below each layer of first filtering layer 4.

When the flue gas passes through the filter 5, the dust in the flue gas is filtered by the multilayer first filter layers 4, the filtered dust falls into the dust hopper 12 along the first filter layers 4, when the dirt in the filter 5 above is too much, the flue gas enters the filter 5 below through the pipeline 3 below by rotating the first valve 2, and then the filter 5 above can be cleaned while the device works.

Behind filter 5 install second valve 6 on the pipeline 3, be connected with a desulfurizing tower 7 on two pipelines 3 of 6 rear end branches of second valve respectively, desulfurizing tower 7 is inside to be provided with multilayer shower head 10, and shower head 10 top is provided with multilayer second filter layer 11, and fixed mounting has heater 8 on 7 rear pipeline 3 of desulfurizing tower, and heater 8 passes through pipeline 3 and is connected with exhaust port 9.

Inside filtered flue gas got into desulfurizing tower 7, desulfurizing tower 7 passed through multilayer shower head 10 blowout desulfurization liquid, carries out the desulfurization to the flue gas, and the flue gas after the desulfurization carries out further filtration through the second filter layer 11 of top and gets into behind the heater 8 heating through pipeline 3 and get into exhaust port 9 and discharge, and heater 8 heating flue gas is used for preventing flue gas corrosion exhaust port 9.

When 7 inside needs of upper part desulfurizing tower wash, through rotatory second valve 6, the flue gas after the filtration will get into below desulfurizing tower 7 through below pipeline 3 and carry out the desulfurization, just can wash top desulfurizing tower 7 simultaneously.

The working principle and the using process of the utility model are as follows: after the device is installed, smoke enters from a smoke inlet 1, the smoke enters an upper filter 5 through an upper pipeline 3 by rotating a first valve 2, when the smoke passes through a plurality of layers of first filter layers 4, dust in the smoke is filtered by the first filter layers 4, then the filtered smoke enters an upper desulfurizing tower 7 through the upper pipeline 3 by rotating a second valve 6, the desulfurizing tower 7 desulfurizes the smoke and then enters a heater 8 through the pipeline 3 to be heated, and then the smoke is discharged through a smoke outlet 9.

When the inside dirt of the filter 5 of top is too much, through rotatory first valve 2, the flue gas will get into below filter 5 through below pipeline 3, then just can be when the device work, wash the filter 5 of top, when 7 inside needs of top desulfurizing tower wash, through rotatory second valve 6, the flue gas after the filtration will get into below desulfurizing tower 7 through below pipeline 3 and carry out the desulfurization, just can wash top desulfurizing tower 7 simultaneously.
