Electrode air mixing device of chimney white smoke eliminating system

Abstract

The invention discloses an electrode air mixing device of a chimney white smoke elimination system. The electrode air mixing device comprises a lower support flange, an upper support flange and a plurality of blades, and a plurality of air ducts gradually shrinking towards the center radially are formed; and an ion air electrode is arranged in each air duct, and each ion air electrode is connectedwith a high-voltage source. When flue gas in a chimney flows through the air mixing device, since a gap among the outer sides of the air ducts of blade pieces is large, and a gap among the inner sides of the blade pieces is small, after high voltage is applied to the ion air electrodes, generated ion air is low in flow rate on the outer side, and high in flow rate on the inner side of the blades,and ion air jet flow facing the inner sides of the blades is formed; the tail portion of the jet flow is a negative pressure area, and consequently external environment air is sucked. With mixing ofcold air, the high-temperature and high-humidity flue gas discharged from the chimney is cooled to form white fog, and the white fog is captured by the white fog eliminating device after entering thewhite fog eliminating device, so that the white fog elimination of the chimney is realized, and finally, the recovery of water resources discharged from the chimney is finished in a high-efficiency and low-cost manner.

Description

technical field [0001] The invention relates to the technical field of flue gas discharge, in particular to an electrode air mixing device of a chimney whitening system. Background technique [0002] In the thermal power industry and some other industries, the overall level of water resource utilization efficiency is still low, and there is considerable room for saving. Actively taking effective measures to improve the comprehensive utilization rate of water and save water has become a necessary condition for the sustainable development of industrial society and the improvement of market competitiveness, and it is also related to the sustainable development of the entire economic society. [0003] At present, the chimneys of many industries often emit "white smoke", which is actually water, and the discharge of "white smoke" is actually a waste of water resources. [0004] In addition to wasting resources, "white smoke" also affects the visibility of surrounding residential...

Problems solved by technology

[0004] In addition to the waste of resources, "white smoke" also affects the visibility of surrounding residential areas and traffic roads, and damages the urban environment; in addition, it may also cause the humidity in the downwind area to rise, and the plume fog falls on the ground, causing the road surface around the cooling tower to become wet. Slippery or icy, which brings a great safety hazard to the surrounding traffic, affects the safe production of the factory, and affects the safe operation of the production equipment around the cooling tower
