The sludge incineration power plant also needs a large amount of water as the traditional thermal power plant, and the water consumption, the energy consumption and the economic benefit of the whole plant are directly influenced by the quality of the design of a circulating cooling water system. The recirculated cooling water system mainly acts for steam condenser, air cooler and oil cooler use, and the recirculated cooling water flow is: circulating cooling water pool → cooling water pump circulating water pipe → equipment (turbine condenser, air cooler and oil cooler) → cooling tower → reflux circulating cooling water pool. Circulating cooling water is absorbed from a circulating cooling water absorption well by a cooling water pump, pressurized and lifted to a steam turbine device for cooling, and cooled water flows back to a circulating cooling water pool below a cooling tower after being cooled to a certain temperature by the cooling tower for recycling. Meanwhile, because the requirement on the fire safety of a power plant is higher, an independent fire-fighting water storage tank is generally arranged and is pressurized by a water pump and then is sent to fire-fighting equipment of the whole plant for extinguishing fire.

Among the prior art at present, the overall layout of sludge incineration power plants is divided into three regions: main plant areas, sewage treatment areas, water system areas, and other facility areas. The main power house area is the core area of the sludge incineration power plant, is provided with an incinerator, a waste heat boiler, a steam turbine generator and auxiliary facilities, and generally occupies the core position of the whole plant. The water system region is provided with cooling tower, water pump room, cooling tower auxiliary facilities, fire-fighting water pool and comprehensive water pump room etc. and the water pump room constitutes relatively independent arrangement region, general arrangement mode with the cooling tower: the cooling water pump is arranged in a water pump room, and a pump room, a dosing room and a power distribution room are arranged in the water pump room; the cooling tower is arranged at the other side of the water pump room, and the cooling tower needs to be separated from the water pump room by a certain distance according to the requirement of the cooling tower on the air inlet, and other buildings protruding out of the ground cannot be arranged in the range of the certain distance around the cooling tower. The arrangement has the main problems of large land utilization, the requirement of the air inlet of the cooling tower increases the land utilization of the area of the cooling tower, other facilities are inconvenient to arrange in the area due to process reasons, local vacant land is easy to form, and land resources are wasted. The situation that the arrangement is not available in a factory area with tight land is often the case, particularly in sludge incineration power plants in some economically developed areas. Since a sludge incineration power plant is usually constructed in an economically developed area, land resources are very short, the available area of the power plant is small, and the land use efficiency needs to be improved, the arrangement of water supply system equipment needs to be optimized.
