Utility model content
The energy-saving sky that the purpose of this utility model is to provide a kind of energy-conserving and environment-protective divides nitrogen water chilldown system.
The energy-saving sky of realizing the utility model object divides nitrogen water chilldown system, comprise air compressor, be arranged on respectively hot water heat exchanger on the interstage cooler of air compressor and last utmost point cooler, described hot water heat exchanger is all connected with hot water lithium bromide handpiece Water Chilling Units, and the cooling water outlet of described hot water lithium bromide handpiece Water Chilling Units is connected with air cooling tower.
The water inlet of described hot water lithium bromide handpiece Water Chilling Units connects separator by water pump, and described separator is connected with circulation, and described circulation connects respectively interstage cooler and cooling air cooling tower.
The import of described air compressor is provided with filter by suction.
Between described air compressor and air cooling tower, be provided with muffler.
The beneficial effects of the utility model are as follows: energy-saving sky of the present utility model divides nitrogen water chilldown system, on the interstage cooler of air separation plant raw air compressor bank and aftercooler, hot water heat exchanger is set, the working heat coolant-temperature gage that hot water lithium bromide handpiece Water Chilling Units is needed is heated to 90 ℃ from 75 ℃, meets its work hot water needs; Hot water lithium bromide handpiece Water Chilling Units utilizes these work hot water to produce the raw air in the next cooling air cooling tower of part chilled water, both reduced the consumption of air compressor cooling circulating water, saved again freon handpiece Water Chilling Units, good energy-conserving effect, operating cost reduces greatly; And have that environmental pollution is little, range of operation is wide, vibrate the advantages such as little, noise is low.
Accompanying drawing explanation
Fig. 1 is the structural representation that energy-saving sky of the present utility model divides nitrogen water chilldown system.
The specific embodiment
Embodiment of the present utility model is as follows: as shown in Figure 1, energy-saving sky of the present utility model divides nitrogen water chilldown system, comprise air compressor 5, be arranged on respectively hot water heat exchanger 6 on the interstage cooler 7 of air compressor 5 and last utmost point cooler, described hot water heat exchanger 6 is all connected with hot water lithium bromide handpiece Water Chilling Units 1, and the cooling water outlet of described hot water lithium bromide handpiece Water Chilling Units 1 is connected with air cooling tower 4.
The water inlet of described hot water lithium bromide handpiece Water Chilling Units 1 connects separator 2 by water pump 3, and described separator 2 is connected with circulation 8, and described circulation 8 connects respectively interstage cooler 7 and air cooling tower 4.
The import of described air compressor 5 is provided with filter by suction 10.
Between described air compressor 5 and air cooling tower 4, be provided with muffler 9.
Air compressor of the present utility model is for making compression process more approach isotherm compression process, be provided with interstage cooler and aftercooler, every grade of delivery temperature is all greater than 95 ℃, and these low grade heat energies need a large amount of cooling waters to be taken away, and make cooling rear air themperature be less than 42 ℃; Hot water lithium bromide handpiece Water Chilling Units be the hot water of working be thermal source, utilize absorption refrigeration principle to produce the refrigeration unit of low-temperature cold water, there is low grade heat energies such as can utilizing waste heat, used heat, geothermal energy and solar energy, so operating cost reduces greatly.
Embodiment recited above is described preferred embodiment of the present utility model; not scope of the present utility model is limited; design under spiritual prerequisite not departing from the utility model; various distortion and improvement that the common engineers and technicians in this area make technical solutions of the utility model, all should fall in the definite protection domain of claims of the present utility model.
