Description
Technical Field
The utility model belongs to the technical field of electrochemistry scale removal equipment auxiliary device, in particular to electrode water inlet and distribution structure of electrolysis water scale removal equipment.
Background
At present, the electrochemical descaling belongs to a novel high-tech technology encouraged by the state, and is an effective means for gradually replacing or replacing the treatment of a chemical dosing method of circulating cooling water, the principle is that by utilizing an electrolysis technology, calcium and magnesium ions in weakly alkaline environment water with pH of 9-13 are formed near an electrolytic cathode net through an electrode group consisting of a cathode net and an anode net to generate precipitates such as CaCO3, Mg (OH)2 and the like in the alkaline environment near the cathode net, so that the aim of removing the hardness and alkalinity in water is achieved, namely, the surface scaling of heat exchange equipment is reduced or avoided, the heat exchange effect is improved, meanwhile, the weakly acidic environment near the anode net can generate free chlorine, ozone and other substances which can sterilize and kill algae under the action of current, therefore, the scale inhibition, sterilization and algae killing functions of chemical agents can be reduced or replaced by utilizing the electrolysis water descaling technology, and the concentration multiple of circulating water is greatly, therefore, the electrolytic water descaling equipment is produced, and comprises a shell, water inlet and outlet pipelines arranged at the top and the bottom of the shell, a cathode net and an anode net arranged inside the shell and a power supply arranged outside the shell and used for supplying power to the whole device, so that the electrolytic water descaling equipment is energy-saving and environment-friendly, improves the circulation multiple of water, reduces the discharge of waste water, does not contain chemical agents, and avoids secondary pollution caused by the chemical agents.
However, factors influencing the scale deposition capability of the electrolytic water scale removal equipment are many, including the structural form of the electrode plate, the plate spacing between the cathode net and the anode net in the electrode group, the electrolysis voltage and current, the water quality temperature and the flow rate between the electrode plates, etc., wherein the ion migration between the electrode groups directly influences the scale deposition efficiency of the electrode, so the scale deposition effect of the electrode group is directly influenced by the water inlet and distribution mode of the electrode group, the existing electrolytic water scale removal equipment includes the equipment manufacturer which has the measures of shortening the plate spacing between the cathode net and the anode net in the electrode group, increasing the electrolysis current and voltage, increasing the temperature of the electrolyzed water, etc., which are the researches on the influence of the ion migration between the electrode groups on the scale deposition of the electrode, but the water distribution device of the inlet water is not researched, the water inlet and distribution mode of the electrode group directly influences the scale precipitation effect of the electrode group, and the influence even exceeds the influence of the electrode distance, the electrode area, the electrolytic voltage, the current and the like.
The existing electrolytic water descaling equipment directly enters water between a cathode net and an anode net, even an electrode group is directly soaked in the water for scale separation, the scale separation effect of an electrode is reduced by the mode, when the electrolytic water descaling equipment without a water distribution device runs, the water enters from the space between the cathode net and the anode net, ions in the water migrate under the action of an electric field, anions migrate to a positive electrode, cations migrate to a negative electrode, and calcium and magnesium ions in the water migrate to the cathode net to generate precipitation, so that the calcium and magnesium ions near the cathode net are required to migrate to the vicinity of the cathode net as much as possible to improve the scale separation effect, the calcium and magnesium ions near the cathode net are easy to precipitate, the calcium and magnesium ions near the anode net are difficult to migrate due to the problem of migration paths, particularly, the migration path of the calcium and magnesium ions is not only subjected to the linear motion under the action of the electric field, but also subjected to the impact force of water flow, the migration path of calcium and magnesium ions is complex, and the calcium and magnesium ions can directly flow out of the electrolytic water descaling device without migrating to the vicinity of the cathode net when flowing through the electrolytic water descaling device, so that the calcium and magnesium ions cannot be precipitated on the cathode net; in addition, the electrolytic power consumption can be increased, when the water electrolysis descaling equipment without the water distribution device runs, water enters from a position between the cathode net and the anode net, ions in the water migrate under the action of an electric field, anions migrate towards the anode net, cations migrate towards the cathode net, and calcium and magnesium ions in the water migrate towards the cathode net to generate precipitation on the cathode net, so that the calcium and magnesium ions must migrate to the vicinity of the cathode net as much as possible to improve the scale separation effect, the calcium and magnesium ions near the cathode net are easy to precipitate, the calcium and magnesium ions near the anode net have the migration path problem, particularly the migration path of the calcium and magnesium ions is not only impacted by the impact force of water flow under the action of the electric field, and therefore if the water distribution device is not available, the electrolysis voltage and the current are increased, the migration kinetic energy of the calcium and magnesium ions is increased, and the scale separation effect of the electrolysis electrode is improved. Therefore, the electrolysis voltage and current are increased, namely, the electrolysis energy consumption is increased; moreover, the arrangement mode has poor alkali removal effect, when the water electrolysis descaling equipment without the water distribution device runs, water enters from the space between the cathode net and the anode net, ions in the water migrate under the action of an electric field, anions migrate to the anode net, cations migrate to the cathode net, CO 32-and HCO 3-in the water migrate to the anode net, CO 32-and HCO 3-near the cathode net generate CaCO3 precipitates, and most of the rest CO 32-and HCO 3-are taken away by water flow, so that the alkali removal effect of the water electrolysis descaling equipment without the water distribution device is poor.
