Novel polymeric aluminum ferric sulphate parparing and curing device

Abstract

The invention discloses a novel polymeric aluminum ferric sulphate parparing and curing device. The novel polymeric aluminum ferric sulphate parparing and curing device comprises a reaction bin, an oil bath groove, a sulfuric acid storage tank, a flow detecting device, a temperature detecting device and a control box, an upper cover of the reaction bin is connected with a stirring device, the temperature detecting device is mounted in the reaction bin, and the reaction bin is communicated with a vacuuming device. The sulfuric acid storage tank is provided with a sulfuric acid solution outlet which is connected with a second material inlet of the reaction bin via a first electromagnetic valve, a pressure pump and a pipeline, and the flow detecting device is mounted on the pipeline. The novel polymeric aluminum ferric sulphate parparing and curing device has the advantages of simplicity and easiness in feeding operation, safety, environmental protection and accuracy in feeding amount; by means of continuous heating and vacuuming, air pressure in the reaction bin can be kept in a low range, a boiling point of water is decreased by low pressure, and moisture in materials can be evaporated in large amount at lower temperature, so that polymeric aluminum ferric sulphate can be dewatered quickly till being cured, and transportation and storage of the polymeric aluminum ferric sulphate are facilitated.

Description

technical field [0001] The invention relates to a novel preparation and solidification device of 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 h...
