Desulfurization absorption tower oxidation air delivery device for thermal power plant

Abstract

The invention belongs to the field of thermal power generation, and particularly relates to a desulfurization absorption tower oxidation air delivery device for a thermal power plant. For solving theproblems of an existing oxidation air delivery device that the oxygen delivery mode is monotonous, the oxygen inflow amount is small, oxygen cannot fill an entire absorption tower in time, and the oxygen cannot make sufficient contact with sulfide when mixed with the sulfide, the following scheme is proposed; the desulfurization absorption tower oxidation air delivery device for the thermal powerplant comprises an absorption tower, a blast chamber is fixedly connected to the bottom side of the absorption tower, a blast mechanism is arranged in the blast chamber, exhaust pipes which are metalpipes are symmetrically and fixedly connected to the absorption tower, first control valves are arranged on the exhaust pipes, and partition plates are fixedly connected to the inner wall of the absorption tower. According to the device, a driving motor drives an output shaft to rotate, then, a conical pipe does circular motion, the oxygen delivery uniformity is improved, oxygen fills the entire absorption tower in time and makes sufficient contact with sulfide, and the desulfurization reaction speed is increased.

Description

technical field [0001] The invention relates to the technical field of thermal power generation, in particular to an oxidation wind delivery device for a desulfurization absorption tower of a thermal power plant. Background technique [0002] Thermal power generation is the main power generation method in my country. As one of the three major main equipments of thermal power plants, power plant boilers are developed along with the development of thermal power industry in my country. There are three types of energy conversion processes in thermal power generation: fuel chemical energy→steam heat energy →Mechanical energy→electrical energy, simply put, it uses fuel to generate heat, heats water, and forms high-temperature and high-pressure superheated steam, and then the steam enters the steam turbine along the pipeline to continuously expand and do work, impacting the turbine rotor to rotate at high speed, driving the generator rotor (electromagnetic field) to rotate, and the s...

Problems solved by technology

[0004] The present invention proposes a desulfurization absorption tower oxidizing air delivery device used in a thermal power plant, which solves the problem that the existing oxidizing air delivery device has a single oxygen delivery method, the amount of oxygen intake is small, and the oxygen cannot be filled in time for the entire absorption tower. Insufficient mixing and contact of sulfides greatly affects the desulfurization reaction speed and the problem of low desulfurization efficiency
