Abstract
Provided is a waste heat recovery absorption heat pump system special for a chemical fiber factory. High-temperature sewage wastewater enters a corrosion resisting water-water heat exchanger after being filtered by a filter. Afterheat water is exported by the corrosion resisting water-water heat exchanger and returns and is discharged to a collecting pool after being absorbed the afterheat by the absorption heat pump. The waste heat recovery absorption heat pump system special for the chemical fiber factory utilizes the absorption heat pump in the field of chemical fiber for the first time. Low-grade steam or hot water heat source of the factory is used for extracting heat of strong acid low-temperature waste hot water to produce hot water for production and life. The original combination of the corrosion resisting water-water heat exchanger and the corrosion resisting absorption heat pump evaporimeter adopts indirect heat exchange method, the heat exchange amount is ensured, and meanwhile the need of acid-proof material of the heat pump evaporimeter and the composite cost are reduced. Years of return of investment of the complete equipment are shortened.

Background technology
The spent hot water that have higher temperatures containing in chemical fibre factory's short fiber and the long fine production procedure, owing to having very high acidity and corrosivity, usually this type of low-grade energy is fallen as direct discharging of waste water at present.On the other hand, in order to solve needed high temperature production water and confession heat problem in the production link, need expend separately a large amount of electric energy again or fossil heat heat energy heats, thereby from energy resources recycling, exist serious utilization of resources irrationality.Therefore, how to take full advantage of the energy resources condition that chemical fibre factory self has, the high-grade energy of taking targetedly measure significantly to reduce relevant production, domestic hot-water and heating supply expends and operating cost, has important technology and economic worth.
Realized recycling the water heating function by the used heat that compression heat pump extracts in the water at sphere of life at present, widely applied at commercial fields such as hotel, bath centers, still needed to expend electric power but compression heat pump carries out Waste Heat Recovery.
Simultaneously, existing recovery industrial wastewater used corrosion-resistant water-often cost is higher for the water heat-exchanger rig, and heat exchange efficiency is low, can't be disposable acquisition produce and use high-temperature-hot-water, be difficult to the scale popularization to such an extent as to regular maintenance is loaded down with trivial details.
For industrial circles such as chemical fibre factories, the place that particularly has more low-grade cheap thermals source such as hot waste water, adopt local existing cheap steam source driving absorption heat pump to absorb cheap waste heat source and produce production and domestic hot-water, comparable simple employing steam or electrical heating water heating can significantly be saved the valuable energy.
Summary of the invention
The purpose of this utility model and task are, develop a kind of corrosion-resistant absorption type heat pump system that is extracted heat by low temperature waste heat water, combine with the corrosion-resistant water-water heat exchanger of particular design, adopt the absorption heat pump technology by corrosion-resistant filter get, sewer, reach the purpose of Waste Heat Recovery.
For achieving the above object, the utility model is by the following technical solutions:
The Waste Heat Recovery absorption type heat pump system of a kind of chemical fibre factory special use, the dirty waste water of high temperature enters corrosion-resistant water-water heat exchanger after being filtered by filter, and the remaining hot water of corrosion-resistant water-water heat exchanger output returns after absorption heat pump absorbs waste heat and drains into collecting pit.
The remaining hot water of corrosion-resistant water-water heat exchanger output is sent into the evaporimeter of absorption heat pump, and the low-pressure water steam of evaporimeter output is through exporting hot water to hot user behind absorber, generator and the condenser; And the heat source side at generator links to each other with heating source.
Described absorption heat pump is single-effective absorption heat pump or double effect absorption type heat pump.
The material of evaporimeter adopts corrosion resistant Hastelloy in the described absorption heat pump.
The material of described water-water-to-water heat exchanger adopts corrosion-resistant polytetrafluoro.
Described absorption heat pump and water-water-to-water heat exchanger consist of one group of heat pump group, enter at least one heat pump group through the dirty waste water of the high temperature of filter output.
Adopt the utility model of technique scheme, adopt first absorption heat pump to utilize in the factory low-grade steam or heat source of hot water to extract highly acid low temperature waste heat water heat in the chemical fibre field and produce and hot water for life to produce; Corrosion-resistant water-hydrothermal exchange and the corrosion-resistant absorption heat pump evaporator combinations of original creation adopt the indirect heat exchange mode, when guaranteeing the heat exchange amount, have reduced evaporator with heat pump acid resistance material demand and integrated cost.Shortened the Payback years of package unit.
