Abstract

The invention discloses a conical tray and an application thereof. The conical tray includes: a conical disc, several through holes arranged on the conical disc, helical guide vanes arranged in the through holes, arranged on the diameter of the conical disc The largest support column; wherein, a cavity is formed between the outer wall of each through hole and the upper surface of the conical disc and the lower surface of the conical disc, and the outer wall of each through hole is provided near the upper surface of the conical disc. A hole, a channel communicating with the cavity is set in the supporting column, and the channel is in communication with the slurry outflow pipeline; the supporting column is used to support and fix the conical disk. The invention reduces the resistance to the rising flow of the flue gas, further promotes the condensation of the gaseous heavy metals and sulfides in the flue gas to the surface of the tray shell or the surface of the particles through the hollow liquid holding tray, reduces the temperature of the flue gas, and further improves The dust removal efficiency of coal-fired flue gas.

Description

technical field [0001] The invention belongs to the technical field of coal-burning flue gas treatment, and more specifically relates to a conical tray and an application thereof. Background technique [0002] my country's energy composition is dominated by coal, with abundant resources and good peak-shaving performance, making coal-fired power generation still the main power source in my country for a period of time in the future. The flue gas produced during the coal combustion process contains a variety of toxic and harmful substances, so it is necessary to purify the flue gas. Flue gas desulfurization technology can be divided into three categories: wet method, semi-dry method and dry method according to the process and products. Among them, the wet method desulfurization technology has fast reaction speed, high efficiency, high utilization rate of desulfurization additives, low cost, and efficient synergistic removal. Advantages such as sulfides and heavy metals are wi...
