Description
Technical field
The present invention relates to a kind of chlorinedioxide generator apparatus of applying in environmental protection and water treatment field, particularly a kind of using sodium chlorate, acid and reductive agent as reaction raw materials can the separated chlorinedioxide generator apparatus of raffinate.
Background technology
Dioxide peroxide is the sterilant of a kind of efficient, wide spectrum, nothing " three cause " (carcinogenic, teratogenesis, mutagenesis), has been widely used in sterilization, sterilization, algae removal and oxidation, decolouring, the deodorization processing of water.Dioxide peroxide is also a kind of strong oxidizing property gas, has data to show dioxide peroxide when content reaches 7-10% in air, and vibrations, shock, friction, sunlight, heat, electric charge excite etc. all can cause blast, threat to life and property safety.
The chlorine dioxide generator generally using is at present on-the-spotly to take sodium chlorate (or Textone), acid and reductive agent and through chemical reaction, generate dioxide peroxide (also have and generate chlorine simultaneously) as raw material using, and disinfection agent of chlorine dioxide is added to the device in staying water.That is to say reaction product dioxide peroxide, chlorine and raffinate are together added in pending water.Because of the state of the art of chlorine dioxide generator product, the situation of the controlling difference of on-the-spot operation, may cause reaction raw materials transformation efficiency very low, the residual acid of the unreacting material in raffinate (particularly sodium chlorate) waits and is just together added in water, will water body be polluted and be endangered.Particularly raffinate is together added in tap water, will affects water quality reaching standard and threaten HUMAN HEALTH.
Therefore to carry out raffinate separation after chlorine dioxide generator reaction be necessary, in recent years have some patent documentations introduced can raffinate separation " chlorine dioxide generating device " (CN100424004C) and " level Four tower type counterflow chlorine dioxide generator " (CN201580987U).Both all likely realize raffinate separation, but cannot accomplish the continuous self-flowing discharge of raffinate under continuous running status; In addition in disorderly closedown situation, there is the defect of larger potential safety hazard etc.
