Embodiment 1

[0025] Such as figure 1 , the embodiment of the present invention provides a swirl confluence agglomeration tower for flue gas dedusting, comprising a cylindrical tower body 1, the lower part of the tower body 1 is provided with at least one guide pipe 5 for introducing flue gas, the guide pipe The flow pipe 5 is connected tangentially to the tower body 1, and the top of the tower body 1 is provided with a flue gas outlet. The tower body 1 is provided with multiple layers of spray layers 2 for spraying the agglomeration liquid sequentially from bottom to top, and at least between the bottom two layers of spray layers 2 is provided with a turbulent state after the flue gas passes through. Cyclone device 4. In this embodiment, two guide tubes 5 are used, and the two guide tubes 5 are symmetrically arranged along the central axis of the tower body 1. After the flue gas is tangentially introduced into the tower body 1 through the two guide tubes 5, it rotates in the tower body 1 ...

Embodiment 2

[0034] This embodiment provides an ash hopper 3 that can be used in the first embodiment above as the ash hopper 3 installed at the bottom of the tower body 1 . Such as image 3 , the ash hopper 3 is funnel-shaped, including a cone section and a straight section, the cone section is wide at the top and narrow at the bottom, and is used to form a dust collection chamber, and the straight section is connected to the lower end of the cone section to accommodate the collected dust. There is a dust discharge valve on the section, which can clean the collected dust regularly or irregularly.

[0035] Such as image 3 , the above-mentioned conical section includes an outer conical shell 302 and an inner filter layer 303, wherein the outer conical shell 302 is connected to the bottom of the tower body 1, and the conical shell 302 can be a cone or a pyramid, up and down Both ends are open, and the upper end matches the inner diameter of the tower body 1 for smooth docking; the inner f...

Embodiment 3

[0038] In Embodiment 1, the spray layer 2 can be provided with a plurality of spray guns in the inner ring of the tower body 1 to completely cover the spray area along the cross section of the tower body 1 . In this embodiment, a spray device is provided, which can be used as the spray layer 2 in the first embodiment.

[0039] Such as Figure 4-Figure 5 , the spraying device includes a plurality of spraying pipes 202, a plurality of spraying pipes 202 are interwoven to form a network frame for erecting in the tower body 1 along the cross section of the tower body 1, each spraying pipe 202 is provided with There is at least one spray head 203 , and the spray areas of each spray head 203 are combined to form a spray surface that can at least cover the cross section of the tower body 1 . Wherein, each spray pipe 202 can separately enter liquid respectively, also can adopt following preferred structure: each node place of described reticular frame is provided with a multi-way con...

Abstract

The invention relates to a rotation, confluence and agglomeration tower and a method for agglomeration dedusting by adopting the rotation, confluence and agglomeration tower. The rotation, confluence and agglomeration tower comprises a cylindrical tower body, at least one flow guide pipe used for leading in flue gas is arranged on the lower portion of the tower body, each flow guide pipe is connected with the tower body in a tangent manner, and a flue gas outlet is arranged at the top of the tower body; multiple spray layers used for blowing and jetting agglomeration liquid are arranged in the tower body from bottom to top in sequence, and a rotational flow device used for enabling flue gas to form a turbulence state after passing is arranged at least between the two bottommost spray layers. Good agglomeration and dedusting effect can be achieved, subsequent dedusting burden is alleviated effectively, the subsequent dedusting process can even be cancelled, the national flue gas emission standard is met, and meanwhile equipment investment and running cost are lowered.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to a swirling and agglomerating tower and a method for agglomerating and dedusting by using the swirling and agglomerating tower. Background technique [0002] At present, the chemical agglomeration treatment of flue gas is carried out in the flue, such as the patent application with the application number 201410013001.6 on "method and device for promoting the agglomeration of coal-fired ultrafine particles", and the application number 201110422719.0 on "based on chemical Split linkage anode type electrostatic precipitator dust removal method and device" patent application, etc. These methods basically adopt the method of spraying agglomeration liquid and flue gas convective mixing in the flue to promote the agglomeration of fine particle dust, which has defects such as relatively low mixing degree of agglomeration liquid and flue gas, and poor agglomera...
