Description
Technical field
The utility model relates to a kind of factory refrigeration system, especially relates to a kind of refrigeration system of grid-connected reduction cool cycles water consumption.
Background technology
Cooling circulating water system is widely used in each production fields such as iron and steel, PETROLEUM PROCESSING, chemical industry, thermoelectricity, especially chemical industry, each water cooling heat exchanger position height differs, understand according to existing chemical process device, in set of system, most heat exchanger position is at below 20m, fraction heat exchanger is arranged higher, reaches more than 30m.Cooling circulating water system is as an important auxiliary facility in art production process, by water circulating pump, cooling water is delivered to each heat exchanger heat exchange cooling, cooled recirculated water is transported to cooling tower cooling by the road, forms the cooling circulating water system of a set of open type.According to least favorable situation determination water pump nominal parameter during design, wherein metered flow is according to system maximum heating load, the most high state design of environment temperature; Rated head can meet least favorable point according to circulation and design.Energy consumption required for water pump is directly proportional to pump head first power, therefore, often cause and significantly improve the overall pressure of supply water of pumping plant to meet the requirement of least favorable point (peak) pressure of supply water, Design of Pump Station energy consumption is directly caused to rise significantly, meanwhile, the phenomenon also causing low district's heat exchanger heat exchange pressure of supply water obviously to waste.
Especially paint shop all needs technique chilled water all the time, existing refrigeration system has refrigerator, coolant pump, cooling tower, the compositions such as cooling pond, the water that cooling water pump gets out can also supply other equipment of little consumption, so technique refrigeration system comprises refrigerator and cooling water pump is all often open, but different consumptions in season is but not identical, only need out little freezing unit and corresponding cooling system winter, need out large freezing unit and cooling system summer, other equipment are had now to need the cooling water of less flow and the cooling water of refrigeration system to carry out shared cooling water, be incorporated to large pipe network or little pipe network all can there is corresponding refrigerator and do not operate, only open the situation of cooling water pump, cause the production capacity surplus of cooling water pump.
Summary of the invention
The purpose of this utility model is exactly provide a kind of refrigeration system of grid-connected reduction cool cycles water consumption to overcome defect that above-mentioned prior art exists.
The purpose of this utility model can be achieved through the following technical solutions: a kind of refrigeration system of grid-connected reduction cool cycles water consumption, comprise the little refrigerator of little cooling water pump group and connection thereof, also comprise large cooling water pump group and connect large refrigerator, described little cooling water pump group is all connected pond with large cooling water pump group, it is characterized in that, described system also comprises a lateral, this lateral one end is connected to described little cooling water pump group with on the pipeline be connected between little refrigerator, the other end is connected on the pipeline between large cooling water pump group and large refrigerator, described lateral connects small-sized water equipment by a water pump, be that small-sized water equipment supplies water by little cooling water pump group and large cooling water pump group and lateral and valve.
Described little cooling water pump group is connected in parallel by multiple small pump and forms, and little cooling water pump group is that little refrigerator supplies water, and as required, the switch of by-pass valve control, selects one or more small pump in little cooling water pump group to supply water.
Described large cooling water pump group is composed in parallel by multiple large pump, each large pump connects a large refrigerator respectively, and connecting line between each large pump and corresponding large refrigerator draws a bye-pass, this bye-pass arranges by-pass valve control, then be connected to described lateral, select any platform large pump to be that small-sized water equipment supplies water by the opening and closing of each by-pass valve control.
Described lateral is also provided with valve, by the opening and closing of valve, controls whether to select cooling water pump group to be that small-sized water equipment supplies water.
Each valve all has central controller controls.
Compared with prior art, the utility model, after each cooling water pump, all picks out pipeline before refrigerator and to a place, eachly picks out the pipeline place mounted valve come, and to the pipeline place pipe laying pump again at a place, then receive with in the less small-sized water equipment of cooling water inflow.Because no matter when, no matter freezing unit is that large or little affirmative all opens one to I haven't seen you for ages, so the cooling water pump of correspondence also at least leaves one, the consumption of small-sized water equipment is all very little relative to the demand of refrigerator and the ability of cooling water pump, as long as so by the adjustment of valve, whenever can ensure that small-sized water equipment has cooling water to use.
The utility model makes full use of all cooling water pumps, changed into the water supply of the equipment of little consumption by original isolated operation cooling water pump that may need, all the time shunt when giving refrigerator Cooling Water and supply water to the small-sized water equipment of little consumption, reduce the energy consumption of cooling water pump, reach energy-conservation effect.
Accompanying drawing explanation
Fig. 1 is the utility model system architecture schematic diagram.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment 1
As shown in Figure 1, a kind of refrigeration system of grid-connected reduction cool cycles water consumption, the little refrigerator 4 comprising little cooling water pump group 2 and connect, also comprise large cooling water pump group 6 and connect large refrigerator 7, described little cooling water pump group 2 is all connected pond 1 with large cooling water pump group 6, described system also comprises a lateral 8, this lateral 8 one end is connected to described little cooling water pump group 2 with on the pipeline be connected between little refrigerator 4, the other end is connected on the pipeline between large cooling water pump group 6 and large refrigerator 7, described lateral 8 connects small-sized water equipment 5 by a water pump, be that small-sized water equipment 5 supplies water by little cooling water pump group 2 and large cooling water pump group 6 and lateral and valve.
