In order to avoid the lamps and lanterns arrangement from touching the pipelines and process equipment, and the lighting light from being covered by large beams and columns, the lighting design should be designed in such a way that the lighting effect is affected.

In order to avoid the lighting arrangement and pipeline, process equipment, lighting light by large beams and large columns cover, affecting the lighting effect, lighting design must pay attention to the cooperation and contact with the relevant specialties in order to meet the required illumination value.

(2) Cement plant dust, and more for the water condensation dust, lamps and lanterns after the accumulation of dust to affect the illumination, due to the number of more difficult to clean up in time, so the design must take into account this feature, should be included in the compensation factor.

Compensation factor should be taken into account. In order to reduce the maintenance workload, it is appropriate to choose the light source with longer life.

(3) firing workshop clinker export temperature is sometimes as high as nearly 1,000 degrees, dry process cement plant kiln exhaust gas export temperature, high temperature fan temperature is also very high, lamps and lanterns or electrical piping near high temperature will be easy to damage, and unsafe.

Easily damaged, and unsafe, so the provisions should be away from these high-temperature places.

(4) Lighting design must consider the future maintenance. General maintenance with a standing ladder or double ladder, so the installation height should not be too high. For the wall, column installation of lamps and lanterns can be a little higher, and set up in the plant

Between the lamps and lanterns, if not the use of crane maintenance, because the ladder can not be too high, so limit its maximum height should not be greater than 4.5.

(5) Cement plant lighting methods, there should be general lighting, local lighting and mixed lighting. In a workplace, should not be installed only local lighting. Installation of local lighting in the workplace, should be

(6) The lighting power supply line should be safe and reliable; the wiring should be far away from the heat source in the vicinity of firing workshop, high-temperature fan and heat pipeline.

(7) High-efficiency and energy-saving new light source and mixed lighting should be adopted according to local conditions.

2. The illumination standards shall comply with the following provisions:

(1) The minimum illuminance value of indoor and outdoor lighting shall comply with the provisions of the corresponding specifications. The specification does not include, can refer to the illuminance value of similar places. Calculation of illuminance, should be counted compensation coefficient

Number.

(2) The illuminator voltage should not be higher than 105% of its rated voltage, should not be lower than 95% of its rated voltage.

3. Lighting source selection should be consistent with the following provisions:

(1) lighting light source should be cold light source.

(2) Emergency lighting should be used to instantaneous ignition of incandescent or fluorescent lamps, can also use standard emergency lights.

(3) kiln, mill, crushing and other major production workshops, straight with high-pressure sodium lamps, fluorescent high-pressure mercury lamps and other long life, vibration-resistant light source; laboratory, design room, control room, telephone room, fire-fighting office, etc. should use fluorescent lamps.

Laboratory, design room, control room, telephone room, fire-fighting office, etc. should adopt fluorescent lamps. Pre-homogenization yard, pre-homogenization library and other large area lighting places, it is appropriate to use floodlights, high-pressure sodium lamps, metal halide lamps, etc.: a variety of storage and conveyor belt corridor straight with fluorescent lamps.

Library and conveyor belt gallery straight with fluorescent lamps and incandescent lamps.

4. The selection of lamps and lanterns should comply with the following provisions:

(1) lamp type in accordance with the environmental conditions and the light distribution requirements on the illuminated surface, lamp efficiency and other reasonable choice.

(2) pit, pump room, bathroom, cement warehouse bottom, packaging platform and other wet or dusty places, it is appropriate to use waterproof and dust-proof lamps; outdoor corridors should be selected waterproof lamps. Layer height over

When the floor height exceeds 7m, deep cover type factory lamps should be used; the lighting design of coal powder preparation workshop should meet the fire prevention requirements, and waterproof and dust-proof lamps can be selected for the lamps; the oil pump room, indoor oil depot, automobile depot, etc. should be selected for the anti-explosion lamps.

Explosion-proof lamps should be selected.

(3) When the installation height of the illuminator is lower than 2.2m, there should be safety protection measures.

5. The choice of lighting voltage should be consistent with the following provisions:

(1) general lighting voltage should be 220V;

(2) The supply voltage of portable traveling lamps for general maintenance should not exceed 36V:

(3) installed in high temperature, humidity, conductive ground, the installation height of 2.2m from the ground and below, easy to reach and no measures to prevent electric shock (such as not installed leakage protector, etc.) of the lighting

Lighting fixtures, the use of voltage should not exceed 24V:

(4) The voltage of portable lamps used for maintenance in kilns, mills, dryers, pen coolers, electric precipitators, large bag dusters and other metal conductor equipments should not exceed 12V.

3.Lighting management system
