A high-pressure micro-mist humidification system water supply unit and its high-pressure micro-mist humidification system

Abstract

The invention discloses a high-pressure micro fog humidifying system water supply unit and a high-pressure micro fog humidifying system with the water supply unit. The high-pressure micro fog humidifying system comprises the high-pressure micro fog humidifying system water supply unit and a high-pressure micro fog humidifier. The high-pressure water supply unit comprises a water inlet filtering unit, a pressurizing water outlet unit, a control unit and a power supply unit; the water inlet filtering unit filters and purifies water, and then the water is pressurized by the pressurizing water outlet unit so as to be conveyed to the high-pressure micro fog humidifier, so that the high-pressure micro fog humidifier humidifies a plurality of independent or complex humidifying areas. In the control unit, a programmable controller is based on current signals of a pressure transmitter of the pressurizing water outlet unit and combined with a PID algorithm to output analog signals to control the operation frequency of a frequency changer according to parameter instructions set by a user; and a motor achieves constant-pressure water supply according to the running frequency of the frequency changer, so that high-precision, multi-area, divided-period and other types of complex humidity control can be achieved.

Description

technical field [0001] The invention relates to a high-pressure micro-mist humidification technology, in particular to a high-pressure micro-mist humidification system water supply unit and a high-pressure micro-mist humidification system. Background technique [0002] The high-pressure micro-mist humidifier uses a high-pressure plunger pump to increase the water pressure to 4-7Mpa, and then the pressurized water is atomized by a professional nozzle through a high-pressure resistant delivery pipeline to generate microscopic particles with a diameter of only 0.5μm to 15μm. Fog particles can quickly absorb heat from the air to complete vaporization and diffusion, thereby completing the humidification and cooling of the air. Because the high-pressure micro-mist humidifier has the advantages of fine mist, energy saving, safety and reliability, it is especially suitable for humidifying large spaces in industries such as textiles, cigarettes, electronics, industrial dust removal, ...

AI Technical Summary

Problems solved by technology

[0003] The existing high-pressure micro-mist humidifiers are all integrated with water pressurization and regional humidity control. They do not have the function of frequency conversion, and cannot maintain a constant pressure in the working state of dividing time and frequently opening multiple pipelines. Therefore, the traditional humidifier is still used. Single-pipe, large-area unified opening humidification method, and the pressure setting still uses manual mechanical valve to adjust the water pressure value, low precision, high failure, loud noise, shortening the service life of the plunger pump and motor

The humidity instrument controller is used for control, and it has no functions such as information storage and printing, fault shutdown alarm, safety protection, maintenance shutdown reminder, etc. It cannot be connected to the host computer and monitor the regional environment in real time, so it is difficult to meet the requirements of today's multi-region, cross-region, and multi-tube road, time division, different humidity values, data monitoring, fault alarm, maintenance reminder, safety protection, real-time monitoring and other complex intelligent control requirements, because it does not have intelligence, maintenance and troubleshooting are difficult, resulting in frequent faults

[0004] In addition, the above-mentioned high-pressure micro-mist humidifier does not have the double function of single unit that can directly humidify multiple areas and can be used in combination with the control water distribution unit
