Problems solved by technology

Since the plate as the working part of demisting is solid and has no adsorption effect on mist, the efficiency and effect of demisting are often not very good. The current white smoke from each chimney illustrates this problem.
In addition, the flue gas sometimes contains a large amount of dust, and the existing demisters cannot solve the problem of dust emission.

Embodiment 1

[0015] Combine figure 1 , image 3 The description of the present invention is as follows:

[0016] The rotary flue gas demister is composed of bracket 1, box shell 2, power unit 4 and demister 3. The material of demister 3 is EVA sponge, which is made into a circle corresponding to the cavity of bracket 2. The casing 2 is a cylindrical casing. A power unit 4 is installed on the upper part of the casing. The power unit 4 is composed of an electric motor and a transmission. The shaft 9 connected with the transmission extends into the casing 2, except for the air inlet 5 and the outlet Except for the air port 6 and the water outlet 7, the inside of the box shell 2 is a circular closed cavity, and the mist eliminator 3 and the bracket 1 are placed in the cavity. The mist eliminator 3 is a one-piece, circular ring, and is placed in the bracket 1. On the upper part, the bracket 1 and the rotating shaft 9 are keyed and fixed along the circumference of the shaft 9. The bottom of the bra...

Embodiment 2

[0020] The difference from the first embodiment is that the power unit 4 is not provided with the central part of the case 2, but is provided on the outside of the case 2, and the rotating shaft 9 is not provided. figure 2 with image 3 The description of the present invention is as follows:

[0021] The rotary flue gas demister is composed of a bracket 1, a box shell 2, a power unit 4 and a demister 3. The demister 3 is made of EVA sponge, except for an air inlet 5, an air outlet 6 and a water outlet. In addition to 7, the inside of the box shell 2 is a circular closed cavity, and the demister 3 and the bracket 1 are placed in the cavity. The demister 3 is a whole piece or spliced ​​into a disc shape, placed on the bracket 1, and the support The outer edge of the frame 1 has gear teeth that mesh with the gears on the reducer. The power unit 4 is installed on the outside of the casing 2. The power is transmitted to the bracket 1 through the gears on the reducer, and the bracket 1...

Abstract

The invention discloses a rotary type flue gas demister, which comprises a bracket, a case, a demisting body, and a power device. The demisting body is prepared from a porous elastic water absorbing material. The case is provided with an air inlet, an air outlet, and a water outlet. A round enclosed cavity is arranged in the case. The bracket and the demisting body are arranged in the cavity. Thedemisting body is arranged on the bracket. The bracket is movably matched with the case and is capable of driving the demisting body to rotate in the case. The power device is arranged on the exteriorof the case and drives the bracket to rotate through a shaft. A datum diameter line divides the case into a flue gas side and an extrusion side. The flue gas side is provided with the air inlet and the air outlet, which are connected to a flue gas channel respectively. The lower part of the extrusion side is provided with the water outlet. The inner cavity of the extrusion side is provided with aroller. The roller tightly presses the demisting body and can rotate. The demisting effect is good, the demisting efficiency is high, and impurities such as dusts in the flue gas can be removed at the same time.

Description

Technical field [0001] The invention relates to the field of defogging, in particular to a rotary flue gas defogger. technical background [0002] According to national environmental protection requirements, the elimination of industrial visual pollution is also included in the content of corporate environmental governance. For the elimination of water vapor in industrial flue gas, the current general method is to install a demister in the flue. The structure of the existing demister is mainly composed of plates and supporting devices. The purpose of defogging is accomplished by the plate. Plates are usually made of polymer materials (such as polypropylene, FRP, etc.) or stainless steel, both of which are hard. Generally divided into streamline type and polyline type. Its working principle is that when the gas containing mist flows through the demister at a certain speed, due to the inertial impact of the gas, the mist collides with the plate and the collected droplets are so...
