Preparing and solidifying device for polymeric aluminum ferric sulfate

Abstract

The invention discloses a preparing and solidifying device for polymeric aluminum ferric sulfate. The preparing and solidifying device comprises a reaction bin, an oil bath tank, a sulfate acid storage tank, a flow detection device, a temperature detection device and a control box, and the reaction bin is used for storing high-iron bauxite. An upper cover of the reaction bin is connected with a stirring device. The temperature detection device is installed inside the reaction bin. The reaction bin is communicated with a vacuumizing device. A sulfate acid solution outlet is formed in the sulfate acid storage tank and connected into a second material inlet in the reaction bin through a first electromagnetic valve, a pressure pump and a pipeline, and the flow detection device is installed on the pipeline. Feeding operation is easy, safe and environmentally friendly, the feeding amount is accurate, air pressure inside the reaction bin is kept within a low range through continuous heating and vacuumizing, the boiling point of water is lowered through low pressure, then a lot of water in material can be evaporated at low temperature, rapid dehydration can be performed on the polymeric aluminum ferric sulfate until solidifying is achieved, and therefore transportation and storage are convenient.

Description

technical field [0001] The invention relates to a preparation and curing device for polyaluminum ferric sulfate. Background technique [0002] With the rapid development of industry, agriculture and economy, the problem of water pollution is becoming more and more serious, and the treatment of sewage is getting more and more attention. Then there are many water treatment methods such as biological treatment, chemical oxidation, electrodialysis, ion exchange, adsorption, flocculation and precipitation. In consideration of economical applicability and safe use, the flocculation-sedimentation method is currently the most widely used, most applicable, and relatively cheap method in water treatment, and the choice of flocculant is the key to this method. [0003] In practical application, it is found that polyaluminum ferric sulfate combines the advantages of iron salt and aluminum salt, has the advantages of large molecular weight and fast sedimentation rate, and has been succe...
