Dry reagent powder spraying system

Abstract

The invention discloses a dry reagent powder spraying system. The dry reagent powder spraying system is characterized in that the dry reagent powder spraying system comprises a reagent feeding system,an air feeding system, a mixing system, a reagent discharging system, a regulating system and a drying system; the body of the dry reagent powder spraying system is a circular tank with a tapered bottom, and is used as a mixing tank for the dry reagent powder spraying system, and the reagent feeding system, the air feeding system, the reagent discharging system, the regulating system and the drying system are all attached and fixed to the mixing tank, and are mutually regulated to control the feeding of a dry reagent powder. In previous sewage treatment, bubbles are often generated at the surface of sewage due to the drop, and the reagent powder cannot sufficiently react with the sewage and is discharged after meeting the bubbles, so the addition amount of the reagent powder is increased,poor sewage treatment effect and reagent wastes are caused, and the sewage treatment cost is increased. The dry reagent powder spraying system provided by the invention can overcome the above deficiencies of the prior art, and can directly and fully contact the reagent powder with the sewage, improve the treatment effect, reduce the use amount of the reagent powder and reduce the running cost.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a chemical spraying device which can be used for direct mixing of dry powder and sewage. Background technique [0002] Many industrial wastewater and domestic sewage contain heavy metal ions, suspended solids, Escherichia coli and other substances harmful to the human body, which need to be treated before they can be discharged. When sewage is treated, it is often necessary to add powdered treatment agents. During the treatment process, the sewage and the agents are fully contacted and fused to play the role of the agents. Due to the continuous injection and discharge of sewage during the process of adding chemicals, the surface of the sewage is caused by the drop during the injection process. Bubbles will be formed, and after the powder medicine and the bubbles are in contact, part of the sewage will be discharged before it can react with the medicine and the dosage wil...
