Recently, the customized waste liquid recovery and transportation system solution developed by our company for a leading domestic PV manufacturer has been successfully put into operation. Addressing common industry pain points in PV waste gas treatment, including complex working conditions, special media and frequent equipment failures, this project adopts a complete delivery system with dedicated air-operated double diaphragm pumps. It drastically boosts the efficiency of waste liquid recovery and transportation, enabling customers to achieve both cost reduction and production stability. The project also delivers a mature, replicable implementation model for resource-based recovery and transportation of waste gas and waste liquid in the photovoltaic industry.
Project Background
Waste gas scrubbing and purification serves as a core environmental protection procedure in PV cell manufacturing. Stable transportation and efficient recovery of scrubber waste liquid directly determine enterprises'environmental operation efficiency, production line continuity and production cost control.
Unlike general industrial wastewater, scrubber waste liquid in the photovoltaic industry features highly complex compositions, which impose extremely high requirements on conveying equipment in terms of corrosion resistance, anti-clogging performance, explosion-proof capability and adaptability to harsh working conditions.
The customer encountered the following challenges:
The waste liquid generated from waste gas scrubbers contains complex media such as acidic and alkaline corrosive fluids, solid particles, sludge, crystalline substances, foam and high-viscosity cleaning waste liquid. Some working areas carry explosion and fire risks, while conventional centrifugal impeller pumps are prone to jamming and blockage. These issues not only trigger production shutdowns and lower operational efficiency, but also incur heavy labor and maintenance costs, severely disrupting the continuous operation of production lines and environmental protection facilities.
Hono Solution: Complete Conveying System with Air-Operated Diaphragm Pumps
To tackle the customer's harsh and complex waste liquid working conditions, Shaanxi Hono Electronic Technology Co., Ltd. leverages years of experience delivering fluid transportation solutions for the photovoltaic sector. Abandoning traditional centrifugal pump designs, we tailor a complete solution consisting of DN80 air-operated double diaphragm pumps paired with an intelligent control system. The design fundamentally eliminates equipment malfunctions, accommodates full-range waste liquid transportation demands, and realizes automatic, intelligent and unattended stable operation.Core configurations are listed below:
· DN80 Air-Operated Double Diaphragm Pumps
· Intelligent Control System
· High & Low Liquid Level Alarm Devices
· Liquid Level Sensors
Project Achievements
Following commissioning, the overall operational stability of the system has been greatly improved:
✔ Automated control of waste liquid transportation with remote operation and monitoring support
✔ Effectively eliminates blockage and pump jamming, drastically cutting equipment failure rates
✔ Enables continuous and steady system operation with significantly fewer shutdowns for maintenance
✔ Reduces manual inspection and maintenance costs while enhancing on-site operational safety
Operational data indicates that the overall waste liquid transportation efficiency of the customer's scrubber system has increased by 30% after renovation. Equipment failure rates have been greatly lowered, which effectively reduces spare part replacement expenses and production losses caused by equipment downtime. Long-term operation and maintenance expenditures, as well as labor costs for on-site duty and overhaul, are substantially cut. The solution delivers multi-dimensional value: stable equipment performance, improved production efficiency and lowered maintenance costs.
Project Summary
The successful launch of this project once again proves the core strengths of our complete air-operated diaphragm pump solutions under PV-specific harsh conditions featuring high impurity content, strong corrosion and explosion hazards.
Going forward, our company will keep supplying more reliable fluid transportation equipment and system integration solutions for photovoltaic, new energy, chemical and environmental protection industries. We support clients in realizing industrial operation goals including safe production, efficient facility management, quality improvement and cost reduction.
