Description

Resin quantity monitoring device of resin regeneration equipment of fine treatment system Technical Field The invention relates to the field of water treatment, in particular to a device for monitoring the resin amount of a resin regeneration device of a fine treatment system. Background In industrial systems such as thermal power generation and nuclear power, steam generated by a steam turbine is condensed into condensed water, but the condensed water may still contain a small amount of impurities (such as Fe 3+、Cu2+, a metal corrosion product, na +、Cl-, ammonia and the like). These impurities, if entering the boiler or turbine, can lead to fouling, corrosion or reduced efficiency of the equipment. Therefore, the condensed water needs to pass through a fine treatment system, and the ion exchange resin is utilized to selectively adsorb impurity ions so as to realize deep purification. The ion exchange resin has limited exchange capacity, and as the operation time is prolonged, active groups on the resin can be gradually occupied by impurity ions ("saturated") and can not continuously adsorb new ions, and at the moment, the resin is invalid, and the exchange capacity of the resin needs to be recovered through regeneration. The resin regeneration process involves a plurality of steps such as backwashing, regeneration, replacement, forward washing and the like, and the accurate control of the resin quantity in the whole process directly determines the regeneration effect and the system operation efficiency. If the resin content in the regeneration equipment is insufficient, the utilization rate of the regenerant is reduced, the regenerated resin performance cannot reach the standard, the treatment effect of a finishing system is affected, even the downstream equipment is caused to be failed, if the resin content is excessive, the internal space of the equipment is crowded, backwashing is incomplete, the resin layer is agglomerated, the regeneration quality is reduced, and the running energy consumption and the abrasion of the equipment are increased. Therefore, the real-time and accurate monitoring of the resin quantity in the resin regeneration equipment is a key link for guaranteeing the stable and efficient operation of the fine treatment system. In the current industrial field, the resin quantity monitoring of the resin regeneration equipment adopts two modes of traditional manual monitoring and indirect parameter calculation. The manual monitoring mode is usually that under the shutdown state of regeneration equipment, the resin quantity is estimated through means such as manual uncovering observation, sampling weighing, and the like, and the mode is low in efficiency, influences the production continuity, and the manual observation has subjective errors, so that the weighing process is tedious, dynamic monitoring cannot be realized, and the continuous production requirement is difficult to meet. The indirect parameter estimation mode estimates the resin quantity by monitoring indirect parameters such as inlet and outlet flow, pressure difference, regenerant consumption and the like of the regeneration equipment and combining an empirical formula, but the method is easy to be interfered by various external factors such as water quality fluctuation, resin abrasion, equipment leakage and the like, has lower estimation result precision and larger error, and can not provide accurate data support for the adjustment of the resin regeneration process. Based on the above, the application provides a resin amount monitoring device of a resin regeneration device of a finishing system. Disclosure of Invention The application provides a resin quantity monitoring device of a resin regeneration device of a fine processing system, which has the advantages that active vibration of an ultrasonic probe is utilized to uniformly disperse resin in a resin regeneration barrel, influence of resin aggregation and stacking on resin quantity measurement is reduced from the source, accuracy of resin quantity monitoring is improved, and through real-time monitoring of volume and quantity in a resin regeneration process, on-line tracking and quantitative analysis of resin quantity change are realized, so that the technical problem of the background technology is solved. In order to achieve the aim, the resin quantity monitoring device of the resin regeneration equipment of the fine treatment system comprises a liquid level meter, a resin uniform distribution unit, a counting unit and a visual monitoring unit, wherein the liquid level meter is arranged on a resin regeneration barrel, the counting unit and the visual monitoring unit are arranged at the bottom end of the resin regeneration barrel, the resin uniform distribution unit comprises an ultrasonic generator and at least one ultrasonic probe positioned in the resin regeneration barrel, the ultrasonic probe is electrically connected with the ultrasonic generator through a cable an
