Embodiment Construction

[0022] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0023] Such as figure 1 and 2 As shown, a method and device for eliminating desulfurization white smoke comprises the following steps:

[0024] In the first step, the flue gas is rapidly frozen and cooled, and the flue gas to be treated after desulfurization passes through the cooling equipment, so that the flue gas to be treated passes through at least three continuous temperature zones in the range of 10°C to -20°C to cool down in turn, and the flue gas in the flue gas is cooled. The droplet components are condensed at low temperature, and the condensed large droplets are initially separated from the flue gas;

[0025] The second step is the second gas-liquid separation. The flue gas after the first step of quick freezing and cooling is boosted ...

Abstract

The invention discloses a method and a device for eliminating desulfurized white smoke. The method comprises the steps of flue gas quick-freezing cooling, secondary gas-liquid separation and flue gaswarming. The device is simple in structure, flexible, convenient, low in operation energy consumption and high in operation efficiency, can effectively simply the structure of the device, improve thedevice site adaptability and reduce the device construction and maintenance cost, can efficiently eliminate pollutants such as water vapor, liquid drops and the like in smoke, and can reduce the device operation and maintenance cost and the labor intensity in an assisted manner.

Description

technical field [0001] The invention relates to the technical field of flue gas purification, in particular to a method and device for eliminating desulfurization white smoke. Background technique [0002] During the emission of sulfur-containing flue gas, a large amount of white smoke often occurs at the chimney mouth. These white smokes are actually small droplets of sulfuric acid formed by the drop of temperature after the sulfur dioxide contained in the flue gas diffuses into the atmosphere. The "white smoke" phenomenon is quite harmful. First of all, it will directly corrode the steel structure of nearby buildings, greatly reducing its service life. When small droplets of sulfuric acid fall from a high place, it will also damage the surrounding plants. The growth is very harmful. [0003] No matter what kind of desulfurization process is used, the desulfurization efficiency cannot be 100%. On the one hand, it is due to technical reasons, and more importantly, consider...
