In the industrial recirculating aquaculture, the cost of electricity is a matter of great concern to many farmers.
A well-designed breeding workshop may only need 100-200 yuan per day for electricity, while a workshop with poor thermal insulation needs to be 3-4 times as much.
How to effectively reduce farming electricity costs? Today we explore this problem in more detail.
Optimize system design and layout
The first step to reducing electricity costs is to start at the source and optimize the design and layout of the circulating water system.
Rational layout of aquaculture ponds, pipelines, pumps, valves and other components to reduce fluid resistance and improve operating efficiency.
In the planning of the site, the location of the breeding tank should be prioritized, and the rest of the system equipment should be established around the pool as far as possible to reduce the length and elbow of the water supply and drainage pipeline, and reduce the pipe resistance loss.
Use energy efficient equipment
The selection of high-efficiency energy-saving equipment such as high-efficiency motors, variable frequency drive pumps and energy-saving valves can significantly reduce energy consumption during operation.
For example, the use of a microfilter with a main circulating pump behind can avoid the existence of two main circulating pumps in the system, which greatly reduces energy loss.
In addition, large flow and low head pumps should be selected, so that the biofiltration water intake only uses the head pressure of the front pipe, reducing the use of additional pumps.
At the same time, regular maintenance and inspection of the equipment, timely replacement of worn parts, and maintenance of the best performance of the equipment are also important means to reduce the cost of electricity.
Infrastructure insulation and temperature control
The insulation effect directly affects the cost of electricity. If the thermal insulation effect of a workshop is good, even if the heat pump and other heating measures are not opened, the temperature drop is only a few tenths of a degree a day.
Therefore, in the design stage should be the plant insulation, heat insulation as a key topic, to ensure winter cold, frost resistance, summer shade, heat insulation.
The construction of greenhouses can not only avoid direct sunlight on the fish pond, reduce the dissolved oxygen in the water, but also prevent the fish pond from being affected by heavy rain and surrounding pests, and improve the controllability of breeding.
Intelligent management system is introduced
The intelligent management system is introduced to carry out real-time monitoring and data analysis of the whole circulating water system. Automatic adjustment of equipment operating parameters according to actual needs to ensure that the system is always in the best working condition.
For example, by adjusting the speed of the circulating water pump, the sending pressure and flow rate meet the process requirements, and work in the high efficiency interval, avoiding the use of regulating gate valves to consume energy.
Use renewable energy
Renewable energy is also a way to reduce electricity bills.
Renewable energy sources such as solar and wind energy are clean and renewable and can be used as an auxiliary energy source for circulating water systems.
For example, the installation of solar photovoltaic panels to provide power for equipment such as water pumps can both reduce reliance on traditional power systems and reduce long-term operating costs.
