Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of power plant water treatment engineering, and relates to a centrally-arranged boiler make-up water treatment system and condensate water fine treatment regeneration system. BACKGROUND

[0002] In the normal operation process of a power plant, the thermal system water and steam are continuously circulated, but due to the links of blowdown, steam exhaust, leakage and possible external steam supply in the system, water and steam loss will occur, and in order to maintain the overall water-steam balance of the system, the lost water must be supplemented, and this part of water is the boiler make-up water. The boiler make-up water is mostly natural water (including surface water and underground water, etc.) as the water source, which contains impurities such as suspended solids, colloids, anions and cations, microorganisms, etc., which are harmful to the thermal system equipment, and these impurities must be removed as much as possible before being supplemented into the thermal system. In order to prepare the boiler make-up water meeting the requirements, the power plant usually sets up an independent boiler make-up water treatment station in the plant area. The built structures in the boiler make-up water treatment station generally include a boiler make-up water treatment room, an acid and alkali storehouse, a neutralization water tank, a laboratory, a raw water tank, an intermediate water tank and a desalted water tank, etc.

[0003] The condensate water of a power plant is mainly composed of the exhaust steam condensate after the work of the steam turbine and the heater drain in the auxiliary thermal system of the steam turbine. The condensate water is the best component of the feed water, and becomes the boiler feed water after being combined with the aforementioned boiler make-up water. Due to various reasons, these condensate waters are often contaminated to a certain extent, and the impurities mainly include two categories: one category is dissolved salt, which is composed of the residual salt from the boiler make-up water treatment system, the salt carried by the steam and the salt leaked from the condenser, etc.; the other category is the corrosion products of the thermal system metal, such as iron and copper oxides, etc. For a high-parameter and large-capacity generator unit, in order to ensure the high quality of the water-steam system, the condensate water must be fine treated. The condensate water fine treatment currently mostly selects the processes of filtration and desalination, and the desalination unit mostly adopts a mixed bed or a positive and negative separation bed device, which is filled with a condensate water fine treatment special resin in the bed body. The resin is regenerated by acid and alkali outside the body after running failure, and therefore a matching fine treatment regeneration system must be set up. Since the condensate water fine treatment regeneration system mainly serves the condensate water treatment, it is usually set up in the main plant area of the power plant, such as in the steam turbine house, the central control building, the unit drainage tank and other built structures. The specific room and facilities usually include a fine treatment regeneration room (area), an acid and alkali storage room, an acid and alkali metering room, a neutralization water tank, a condensate water storage tank or a fine treatment regeneration water tank, etc.

[0004] As described above, the conventional power plant design mainly considers the system function, and the water treatment facility is often designed and arranged with the service object as the center, thereby causing the boiler makeup water treatment facility to be arranged in the boiler makeup water treatment station, the condensate polishing treatment regeneration facility to be arranged in the main plant area, and the two to be completely independent and not shared by the system. This results in repeated settings of desalted water supply, acid and alkali storage, wastewater storage, wastewater neutralization, wastewater discharge, power supply and distribution facilities, control instruments and corresponding buildings and structures, and significantly increases the project investment cost. In addition, since the main plant is the most core and important building of the power plant, the arrangement of the condensate polishing treatment regeneration equipment in the main plant for a long time, acid mist volatilization causing corrosion of part of the equipment in the main plant and potential safety hazards of the condensate polishing treatment regeneration wastewater leakage to the foundation of the main plant have been the focus of attention for the safe operation of the power plant. With the current new goals of land saving, centralized management, staff reduction and efficiency improvement of the power plant construction project, the disadvantages of the water treatment facility with large occupied area, single function, scattered arrangement and repeated system settings in the conventional arrangement scheme are increasingly prominent, and it is difficult to meet the needs of centralized management and safe operation of the modern power plant.
