Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] see figure 1 and figure 2 A high-efficiency mist eliminator that is not prone to fouling includes passages 21, 22 surrounded by baffles 1 and two baffles 41, 42, and each surface of the spoiler 1 located in the passages 21, 22 is flat. A circular tube 3 is arranged at the turning point of the channels 21, 22, and the tube 3 divides the turning point of the channels 21, 22 into two flow passages, and the sum of the cross-sectional areas of the two flow passages is smaller than the section area of ​​the rest of the passages 21, 22. area. Each baffle plate 41, 42 has a raised portion 4a and a recessed portion 4b, and the shapes of the raised portion and the recessed portion are complementary to each other. Both ends of the tube 3 and the baffle 1 are fixed on the baffles 41,42.

[0018] There are two kinds of passages 21 and...

Abstract

The invention relates to a high-efficiency rarely-scaling demister. The high-efficiency rarely-scaling demister comprises a channel surrounded by a baffle plate, wherein a flow turbulence part is arranged at the turning part of the channel, the flow turbulence part divides the turning part of the channel into two shunting passages, the sum of the areas of the cross sections of two shunting passages is less than the area of the cross section of the other part of the channel; when the sum of the areas of the cross sections of the two shunting passages is less than the area of the cross section of the other part of the channel, the flowing speed of gas in each shunting passage is higher than that of the gas in the other position in channel, as each shunting passage is arranged at the turning position of the channel, entrainments in the gas can impact the baffle plate at high speed, and the demisting efficiency of the demister is improved greatly; and besides, the flowing speed of the gas in each shunting passage is higher than that of the gas in the other position in the channel, liquid drops at the turning position cannot be gathered easily, the liquid drops can be gathered at the areas at the upper part or the lower part of the turning position relatively easily, and the areas are spraying pipes which can be washed easily, so that the scaling can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of desulfurization, in particular to a high-efficiency mist eliminator that is not easy to scale. Background technique [0002] During the operation of the absorption tower, it is easy to generate "fog" with a particle size of 10-60 microns. The "fog" not only contains water, but also dissolves sulfuric acid, sulfate, sulfur dioxide, etc. Contamination and severe corrosion of the flue, therefore, the wet desulfurization process requires demisting of the absorption equipment. The purified gas must be demisted before leaving the absorption tower. The demister is complete. [0003] The demister is divided into two types: baffle half type and circular tube type. The principle of the baffle type demister: when the gas containing mist flows through the demister at a certain speed, due to the inertial impact of the gas, the mist It collides with the baffle plate, and then attaches to the baffle plate to form a dr...
