With the advancement of port technology and the increase of national energy conservation and emission reduction, the pressure on energy conservation and emission reduction of ports has been increasing.
The Ministry of Transport has also clearly put forward requirements for the transformation of existing port technologies through high energy consumption and low efficiency. Equipment is updated to improve the overall technical level of port equipment, reducing energy consumption and waste emissions.
Among them, port lighting equipment is an important aspect. The current floodlights installed in the port generally have problems of large light decay, low power factor, high energy consumption and low color rendering index, and no automatic control is realized.
Therefore, this paper proposes several typical energy-saving technologies and implementation strategies for the current mainstream lighting technology, starting from the port terminal warehouse and lighting energy-saving renovation problems. Finally, the design of the port lighting control system is discussed from the actual situation, and an integrated energy-saving system is proposed.
- Dock lighting energy-saving transformation technology,
Take the warehouse of a port as an example. The warehouse has a total length of 124m and a width of 68m. It is divided into four rooms and the height of the warehouse roof is 13m. The main function of the warehouse is to transfer food such as soybeans and soybean meal. Currently used is a 110w lamp.
- The length of each span of the warehouse is about 5m, a total of 25 spans. Each of the spans is installed with such a sodium lamp, a total of 100 sets. The installation height of the luminaire is 8m, its illumination is 4.1lux, and it has reached the national standard (15-50lux), which brings certain hidden dangers to safety work.
1.1 Basic lighting requirements for warehouses
1.1.1 Illumination requirements
According to the National Lighting Commission (CIE) and China’s current lighting design standards, combined with the lighting requirements of the port, the average illuminance of the warehouse should be above 15-50 lux.
1.1.2 Lighting performance requirements
Due to the electrical safety requirements of the granary and the long-term reliable work requirements, and in order to avoid accidents, the luminaires with good insulation and protection against electric shock should be selected: at the same time, because the warehouse stores food items, dust Larger, so ensure that the lamps have good dust protection and air tightness, prevent pollutants from entering the lamps and reflectors, resulting in reduced illuminance. At the same time, the lamps should also have anti-corrosion, waterproof and dustproof functions.
1.1.3 has good color rendering and light color
Light sources with good color rendering and light color can create a better working environment for people, and work colleagues who improve work efficiency can reduce the fatigue of people working under the light. Therefore, a metal halide lamp with better color rendering and light color can be selected.
1.2 Selection of lamps
According to the relevant requirements of the above-mentioned warehouse for lamps, razorlux 150w led lamps are selected under the conditions of comprehensive consideration of dustproof, energy-saving and maintainable lamps of lamps, and the relevant parameters are as follows:
The insulated lamp is class 1 and has the function of protection against electric shock; the anti-corrosion grade is WF2, which can adapt to various corrosive work situations; it has the highest enclosure protection grade of IP65, which can effectively prevent dust from entering, with up to 0.9 Power factor, high energy utilization, and obvious energy saving effect.
1.3 Arrangement plan and average illuminance value of the transformation plan
(1) In the design process, the average illuminance of the illumination scheme is calculated by the luminous flux method, and the illuminance of each region is obtained, and a light distribution curve is obtained, as shown in the following figure.
The program uses a total of 48 sets of razorlux 150w anti-glare luminaires, which are installed for side wall installation, the height of the installation is still 8m before, the inclination of the luminaire is 40 degrees, and the illumination reaches the national minimum standard.
