Embodiment Construction

[0016] The concrete technical scheme of the present invention will be further described below in conjunction with embodiment:

[0017] For the heating center with a heating area of ​​5 million square meters, five steam boilers of 35 tons (8 tons of coal per hour) boilers + 8 units of lithium bromide absorption heat pumps with a heating capacity of 40,000 KW are used: daily coal consumption (20 hour) 800 tons, each ton of coal is calculated at 600 yuan, coal consumption per day: 800 tons / day × 600 yuan / ton = 480,000 yuan / day, of which 50% of steam loss is used for lithium bromide absorption heat pump work: 480,000 yuan / day Day × 50% = 240,000 yuan / day, and the remaining exhaust steam at 80°C to 100°C passes through the steam-water exchanger to provide heating at the end of the heating system. 150-day heating period) 240,000 yuan / day × 150 days = 3,060,000 yuan.

[0018] Electricity consumption: The electricity load of the coal-fired boiler heating center of 5 million square me...

Abstract

The invention discloses a city heating system according with a low-carbon energy policy. The city heating system comprises a steam boiler, and is characterized in that: the steam boiler and a lithium bromide absorbing heat pump form a matched combined heating structure through a pipeline, wherein the entering water is heated to steam at the temperature of 150-180 DEG C through the steam boiler and then enters the lithium bromide absorbing heat pump through the pipeline; after the lithium bromide absorbing heat pump works, the generated dead steam at the temperature of 90-100 DEG C is subjected to heat exchange in a steam heat exchanger through the pipeline; then mixed hot water at the temperature of 65 DEG C at least is conveyed to a radiator at the tail end of the heating system for heating; and the mixed hot water at the temperature of 40-50 DEG C, of which the heat is radiated in the radiator at the tail end of the heating system, returns to the steam boiler through the pipeline. In the invention, a power source is replaced by steam so as to absorb high-temperature heat generated by the temperature difference of various reclaimed water sources, thus energy-saving and emission-reducing effects of saving fire coal and reducing carbon dioxide emission can be achieved.

Description

technical field [0001] The invention relates to an urban heating system, in particular to an urban heating and cooling system which is used for urban central heating and cooling and conforms to the low-carbon energy policy, and is an improvement on the current urban central heating and cooling system. Background technique [0002] Low-carbon economy: It is an emerging economic form and development model, including a series of new contents such as low-carbon industry, low-carbon energy technology, low-carbon city and low-carbon life. [0003] The existing urban heating forms are roughly divided into several types: thermal power plants, regional boiler rooms, industrial and urban waste heat, geothermal, nuclear energy, heat pumps, solar energy, etc. The first five are concentrated heat sources, and the latter two, gas furnaces, and oil furnaces are independent heat sources. In areas where centralized heat sources are limited, independent heat sources show their own advantages...
