Winged oxidizing air sprayer pistol

Abstract

The invention relates to a wing oxidation spray gun which pertains to the technical field of wet FGD equipment in a power plant and is characterized in that the extremity of the current linear oxidation spray gun is arranged into an elbow of 90 degrees and the elbow section is provided with flat plate wings that are fixedly connected with the elbow section. Two flat plate wings are symmetrically arranged at the both sides of the elbow section and are parallel to or form an angle of 2-8 degrees with the cross section of the elbow section. The invention is installed and applied in an absorptiontower of a wet FGD system and aims at providing sufficient air for absorption and oxidation reaction of sulfur dioxide in flue gas. Traditional linear oxidation spray gun has the disadvantages of lowoxidation efficiency, large energy consumption, large cavitation effect on a stirrer, etc., while the wing oxidation spray gun can effectively solve the problems. The invention is characterized by reasonable design, simple structure, easy production, convenient application, good stirring effect and high gas-holdup, which can not only improve oxidation efficiency but also reduce the energy consumption of an oxidation air blower.

Description

1. Technical field [0001] The invention relates to a wing-type oxidation spray gun, which belongs to the technical field of wet flue gas desulfurization equipment in power plants. 2. Background technology [0002] With the full implementation of national environmental protection and energy saving policies, wet flue gas desulfurization facilities in thermal power plants have been popularized on a large scale, and the normal operation of wet desulfurization facilities and energy saving and consumption reduction have gradually become the focus of the industry. In most wet desulfurization processes, air is blown into the slurry tank of the absorption tower through an oxidation lance, and then calcium sulfite is forcibly oxidized into calcium sulfate, and gypsum is formed after crystallization. Since the type of oxidation fan has been determined in the design, the oxidation rate is generally 2-3. Under the designed coal type, the oxidation fan can work well; but due to the coal ...

AI Technical Summary

Problems solved by technology

It features simple structure and low production cost, but the disadvantage is that the formed bubbles are large, the diffusion effect in the slurry tank is not good, and a high oxidative air margin is required, which affects economic operation.
