safety distance

It may be arranged in accordance with the requirements specified in the Code for the General Layout Design of Industrial Enterprises: Article 4.3.9 states that circulating water facilities should be located near the production facilities they serve, in areas where the return water can flow by gravity, or in areas where the required pumping head can be reduced. Near the sedimentation tank, there should be space for the accumulation of sludge, as well as facilities for drainage and transportation routes. 　　Cooling towers should be located in areas with good ventilation, where they are protected from dust and water-soluble chemicals that could affect water quality. They should not be placed upwind of outdoor power distribution equipment, as well as railways and roads, along the prevailing wind directions in winter. The minimum horizontal distance between the cooling tower and adjacent facilities shall comply with the provisions of Table 4.3.9. Minimum horizontal distance (m) between cooling towers and adjacent facilities Table 4.3.9 Facility Name Wind-tunnel type cooling tower Mechanically ventilated cooling tower Buildings Central testing laboratory, production control room Open-air production facilities 20 30 25 25 40 30 Outdoor power transformation and distribution installations When the winter prevailing wind blows from the upwind side of the cooling tower When the winter prevailing wind blows from the downwind side of the cooling tower 30 50 40 60 Calcium carbide storage When the year-round prevailing wind blows from the upwind side of the cooling tower When the year-round prevailing wind blows from the downwind side of the cooling tower 30 60 50 100 Piles of raw materials, fuels, and materials that emit dust 25 40 Railway Outside the factory railway (centerline) Railway inside the factory (centerline) 25 15 35 20 Roads Outside the factory roads Roads inside the factory 25 10 35 15 Factory perimeter wall (centerline) 10 15 Note: ① Unless otherwise specified in the table, the distances referred to are measured from the outer wall of the cooling tower ； The building is measured from its outermost axis ； The open-air production unit is measured from the outer wall of the outermost equipment ； Outdoor power transformation and distribution equipment, measured from the edge of the outermost framework ； The yard starts from the edge of the site ； For road types designed for urban use, it is measured from the edge of the road surface; for road types designed for highway use, it is measured from the edge of the road shoulder ； 　　　　②In areas where the outdoor design temperature for winter heating is above 0°C, the distance between the cooling tower and outdoor switching and distribution equipment should be reduced by 25% according to the values specified in the table ； In areas where the outdoor design temperature for winter heating is below –20°C, the distance between cooling towers and adjacent facilities (excluding outdoor power transformation and distribution equipment, as well as piles of raw materials, fuels, and materials that generate dust) shall be increased by 25% based on the values listed in the table ； When the design specifies that the cooling tower shall not use fans during cold seasons, its spacing shall not be increased ； 　　　　③The distance between outdoor power transformation and distribution equipment and cooling towers attached to workshops or production facilities shall be reduced by 25% based on the values listed in the table ； 　　　　④The distance between a single small mechanical cooling tower and adjacent facilities can be appropriately reduced. The distance between fiberglass reinforced plastic cooling towers and adjacent facilities is not subject to the restrictions specified in this table ； 　　　　⑤In renovation and expansion projects, when constrained by conditions, the spacing between columns may be appropriately reduced, but must not exceed 25%.

This distance is not determined by this standard; instead, the design standards for ammonia stations should be consulted to find the safe distance for such stations

Design specifications for ammonia stations? I really hope such a standard exists; please share it with those upstairs. The distance between the ammonia tank and the cooling tower can be determined in accordance with the regulations set out in the design codes for the overall layout of industrial enterprises; the distance between the cooling tower and the production units should be 25 m or 30 m, and the same requirement applies to the ammonia tank.

The distance between the ammonia tank and the cooling tower can be determined in accordance with the regulations set forth in the design codes for the overall layout of industrial enterprises. Mechanical ventilation cooling tower and ammonia tank 30M.
