Heating and cooling system using swallet waste heat by industrial and mining enterprises

Abstract

The invention discloses a heating and cooling system using swallet waste heat by industrial and mining enterprises, relating to the field of residual heat waste heat resource utilization. The heating and cooling system comprises a well-head freeze protection water source heat pump unit (5), a worker bath water source heat pump unit (6), an industrial heating and cooling water source heat pump unit (7), a mine water recycle pump (2), a primary water recycle pump (4), three secondary water recycle pumps, a bath water heating recycle pump (13), two plate-type heat exchangers and a sub-water catcher (17). In the invention, a water source heat pump technology is used and reclaimed water waste heat in a mine water treatment plant is comprehensively utilized for worker bath, industrial heating in winter, well-head freeze protection and cooling of office buildings and apartment blocks in summer; a coal-fired boiler system is thoroughly replaced; a water source heat pump system only extracts the heat of the reclaimed water of the treated mine water and domestic sewage, and additional water resources are not consumed; and the heating and cooling system has the advantages of remarkable energy saving effect, obvious economic benefit, outstanding environmental benefit and the like.

Description

technical field [0001] The invention relates to the field of utilization of waste heat and waste heat resources in coal systems, in particular to a heating and cooling system for industrial and mining enterprises using mine water gushing waste heat. Background technique [0002] In recent years, with the acceleration of industrialization and urbanization, the growth rate of my country's energy consumption has been significantly faster than the economic growth rate, and the contradiction of energy constraints facing economic development has become increasingly prominent. The per capita possession of major mineral resources is less than half of the world's average level. Only about 32%, more than 10 percentage points lower than the foreign advanced level. "The Outline of the Eleventh Five-Year Plan for National Economic and Social Development of the People's Republic of China" proposes that the energy consumption per unit of GDP at the end of the "Eleventh Five-Year Plan" will ...

AI Technical Summary

Problems solved by technology

[0004] Coal enterprises are large energy consumers. Existing coal enterprises basically use coal-fired boiler systems to provide heat sources for mine heating, wellhead antifreeze, and employee bathing. The coal-fired boiler system has the following main problems: (1) High operating costs; ( 2) The environment is seriously polluted; (3) The annual maintenance cost of the coal-fired boiler system is very high, and the system maintenance is complicated

The refrigeration systems of office buildings and apartment buildings now adopt a single refrigeration air source heat pump system. Compared with the water source heat pump system, the air source heat pump system has low energy efficiency ratio, high operating cost and high maintenance cost.
