Intelligent recovery system for water circulation heat energy

Abstract

The invention discloses an intelligent recovery system for water circulation heat energy. Compared with a traditional situation that smoke generated by a boiler is directly exhausted after being cooled by an economizer and a condenser, the design temperature ranges from 80 DEG C to 90 DEG C, heat energy is wasted, water resources are wasted due to cooling, and the cooling effect is not obvious, the system comprises a high-temperature heat generating area, an intermediate-temperature hot water generating area and a low-temperature smoke exhausting area, the temperature of the exhausted smoke can be lower than 45 DEG C and is far superior to the traditional smoke exhaust temperature, the heat energy of the high-temperature smoke generated by the boiler is fully utilized, full utilization ofthe heat energy is achieved, and the economic benefit is improved; meanwhile, condensate water in a workshop is recycled, and used for the economizer and the condenser, the smoke is cooled, and recycling of the condensate water is achieved; the water resources are saved, waste water drainage is reduced, environmental protection, energy saving and emission reducing can be achieved while the production benefit is improved and developed, and the intelligent recovery system is the development trend of the present age.

Description

Technical field: [0001] The invention relates to the technical field of printing and dyeing, in particular to an intelligent recovery system for water circulation heat energy. Background technique: [0002] With the continuous improvement and development of printing and dyeing technology, the development of my country's printing and dyeing industry has been highly valued by the government and the textile industry. In recent years, the state has listed the technological transformation of the printing and dyeing industry as one of the key industries supported by the textile industry, and at the same time has given corresponding policy support in terms of technological development and scientific and technological research, so that my country's printing and dyeing industry has been greatly improved in terms of quality, variety, and efficiency. Great improvement, the overall competitiveness has improved. [0003] At present, the development trend of the printing and dyeing indust...

Problems solved by technology

[0004] In the process of dyeing textiles in the printing and dyeing workshop, boiler heating is required to generate steam for production, but at the same time high-temperature flue gas is generated. The existing dyeing and printing industry uses economizers and condensers for simple cooling After treatment, the flue gas is discharged. The design temperature of the discharged flue gas is between 80°C and 90°C, but the actual online monitoring temperature is as high as 140°C. , resulting in waste of energy. In today's increasingly tense energy supply, energy-saving development and environmentally friendly production are the development trend of the times.
