Embodiment Construction

[0024] The boiler flue gas particle purification device of the present invention is composed of a base 1 , a lower tower body 2 , an upper tower body 3 and a chimney 4 .

[0025] figure 1 It shows that the lower tower body 2 is connected with the base 1 , the upper tower body 3 is connected above the lower tower body 2 , and the upper end of the upper tower body 3 is connected with the chimney 4 .

[0026] figure 1 It shows that there is an air inlet 5 at the lower end of the lower tower body 2, and the boiler flue gas enters the lower tower body 2 through the air inlet 5. A vertical center pipe 6 is installed in the lower tower body 2 , the bottom of the center pipe 6 is connected with the water delivery pipeline, and the circumference of the center pipe 6 is evenly distributed with spray holes 7 . The water is sprayed from the spray hole 7 through the central pipe 6 to remove the smoke particles.

[0027] figure 1 Shown, the lower end of the central pipe 6 is connected w...

Abstract

The invention discloses a boiler fume particulate matter purification device and method and belongs to the technical field of boiler equipment. The device and method are used for purification of boiler fume. According to the technical scheme, the purification device is composed of an upper tower body and a lower tower body, a central pipe is installed in the lower tower body for sprinkling, partial particles in fume are removed, multiple rotational flow cylinders are installed on the upper tower body, and remaining fume particles are removed. The device has the advantages of being simple in structure, convenient to install, small in size and capable of well adapting to the characteristics of the fume of biomass boilers and is novel equipment for fume purification of existing biomass boilers. The device is an innovation for fume purification treatment of the boilers, a wet dedusting mode is combined with a dry dedusting mode, a gas-phase, liquid-phase and solid-phase adhesion principleand an inertial dedusting principle are utilized, a design mode in which the fume is treated by means of a wet pre-dedusting mode and then treated by means of a rotational flow deep purification dedusting mode is adopted, the content of particulate matter in the fume which is discharged outwards is reduced to a great extent finally, and the problem of emission of pollutants in the fume of the biomass boilers is well solved.

Description

technical field [0001] The invention relates to a device and method for purifying boiler flue gas particles, belonging to the technical field of boiler equipment. Background technique [0002] At present, the methods used in the treatment of boiler flue gas particulate matter mainly include four types of methods: bag dust removal, electric dust removal, gravity dust removal and washing dust removal. Among them, bag dust removal is the most widely used method for particulate matter control in biomass boiler flue gas. Biomass boilers mainly use biomass energy as fuel, and the flue gas has the characteristics of complex composition, fine dust, and large dust content. Although the traditional bag filter can reduce the dust emission to a certain extent through the method of film coating, it is still difficult to further reduce the concentration of particulate matter at the outlet due to the limitation of the bag filter itself. [0003] So far, there is no mature particle purifi...
