What are the main contents of water treatment work in thermal power plants? (please hide answer)
It mainly includes water coagulation, sedimentation, clarification and filtration to remove suspended solids and colloids, as well as reverse osmosis, ion exchange, electric desalination and other desalination treatments.
Characteristics of source water, water pretreatment, desalination process, feed water treatment, boiler water treatment, steam quality control, condensate water treatment, treatment and control of cooling water in generators, thermal power plant wastewater treatment and thermal system anti-corrosion, etc.
Prepare desalted water and maintain normal operation of equipment
Thermal power plant water treatment can be summarized as follows:: (1)Water treatment outside the furnace: That is to prepare qualified supply water. (2) Condensate water treatment. (3)Water supply treatment: That is, deoxygenating and adding chemicals to the water supply. (4)In-furnace treatment: That is to do the chemical treatment and sewage discharge of the steam drum boiler water. (5) Cooling water treatment. (6) Chemical supervision of soda water quality.
The main contents include raw water pretreatment to remove suspended impurities, colloidal impurities and organic matter in the source water. Traditional pretreatment methods are coagulation and clarification, mechanical filtration, etc. ; It also includes desalination and degassing of purified water. This part of the treatment mainly removes dissolved salts, that is, various cations and anions in the water, and also includes the removal of harmful gases such as carbon dioxide in the water.

Work content: Start and stop water treatment equipment such as clarification, filtration, desalination, softening or desalination ; Monitor water pressure drop or head loss, measure water turbidity, and backwash filter equipment ; Monitor component analysis instruments, measure water quality, prepare acid and alkali solutions and regenerate softening or desalination ; Start and stop condensate polishing equipment to ensure water supply quality ; The starting and stopping wastewater and sewage departments are deleted and modified, and other wastewater and sewage meet the discharge or recycling standards. ; Adjust drug dosage to ensure cohesion effect and regeneration efficiency ; According to the regulations, safety measures before maintenance of water treatment equipment and acceptance work after maintenance are carried out. ; During unit start-up and chemical cleaning, do a good job of excess water supply ; In accordance with the regulations, conduct patrol inspections of water pumps, chemical pumps and water treatment equipment systems, promptly discover and eliminate hidden dangers, and perform routine maintenance of equipment to ensure safe and economical operation. ; Complete logs, reports and other records on time.
Purify raw water; Deoxidize and add chemicals to the water supply ; Water treatment in the pot ; For once-through boiler units or certain subcritical pressures. Steam drum boiler unit performs condensate water purification treatment ; In thermal power plants, the production return water is treated to prevent scale, corrosion, and organic attachments. ; Supervise the quality of soda and water in all parts of the thermal system ; Chemical cleaning of thermal equipment and maintenance work during shutdown of boilers
The main task of water treatment is to remove dissolved salts in water to meet the boiler water supply standards.
I want to see the answer. Is it a trap?
