Abstract
The utility model discloses an energy -conserving cooling arrangement of BOPP production line, including cooling water set system, refrigerated water water pump and refrigerated water cistern, the cooling water set system includes cooling water set, cooling water water pump and cooling tower, and the cooling water set passes through the temperature valve to be connected with basin heat exchanger with extremely cold roller heat exchanger, is equipped with the cryogenic cooling tower on the refrigerated water heat accumulation pond and freezes the water pump, and the circulation water yield of cryogenic cooling tower is 800 tons, and the flow that freezes the water pump is 800m3h, and cryogenic cooling tower and cooling water set system can the simultaneous workings, the utility model discloses an increase by one set of high -efficient cryogenic cooling tower system on former cooling water set system basis, change the back and do not have the influence to former system, and increased the flexibility of operation of system, improved the ability of guaranteeing the continuous nature of production, save the charges of electricity, practiced thrift manufacturing cost.
Description
Technical field
The utility model relates to a kind of BOPP field of film preparation, is specifically related to a kind of BOPP production line energy-saving cooling device.
Background technology
The production of BOPP film is that first the melt of macromolecule polypropylene is made sheet material or thick film by long and narrow head, then in special stretching-machine, under the speed of certain temperature and setting, simultaneously or the stretching carried out in vertical both direction of substep, and through suitable cooling or heat treatment or the special film be processed into.
Be delivered directly to production line after current each BOPP corporate boss will use handpiece Water Chilling Units to produce chilled water and carry out heat exchange to control chilling roll temperature.And handpiece Water Chilling Units is a power consumption rich and influential family.As the production capacity BOPP production line that is 90 tons/day needs a supporting refrigerating capacity to be that the handpiece Water Chilling Units of 250 standard tons can ensure normally to produce required chilled water supply.The cooling electricity charge are no small costs concerning enterprise, therefore under the prerequisite not affecting product quality, carry out reducing energy consumption can decrease enterprise's production cost to cooling device, improve the competitiveness of BOPP product on similar market.
Utility model content
For the problems referred to above, the utility model provides a kind of BOPP production line energy-saving cooling device, its object is to: transform cooling device, saves the mass energy in producing.
Technical solution of the present utility model:
A kind of BOPP production line energy-saving cooling device, comprise water chilling unit system, chilled water water pump and chilled water cistern, described water chilling unit system comprises handpiece Water Chilling Units, cooling water water pump and cooling tower, described handpiece Water Chilling Units is connected with extremely cold roller heat exchanger and tank heat exchanger by temperature valve, it is characterized in that: described chilled water thermal storage tank is provided with low-temp cooling tower and chilled water pump, the quantity of circulating water of described low-temp cooling tower is 800 tons, the flow of described chilled water pump is 800m3/h, and described low-temp cooling tower and water chilling unit system can work simultaneously.
The power of described handpiece Water Chilling Units is 175KW.
The power of described chilled water pump is 110KW.
The beneficial effects of the utility model:
The utility model by increasing a set of high-efficient low-temp cooling tower system on former water chilling unit system basis, after replacing on original system without impact, and add the operating flexibility of system, improve the ability ensureing to produce continuous property, save the electricity charge, saved production cost.
Accompanying drawing explanation
Fig. 1: the utility model structural principle schematic diagram.
Wherein: extremely cold roller heat exchanger 6 tank heat exchanger 7 low-temp cooling tower 8 chilled water pump of 1 chilled water water pump 2 chilled water cistern 3 water chilling unit system 3-1 handpiece Water Chilling Units 3-2 cooling water water pump 3-3 cooling tower 4 temperature valve 5.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further:
As shown in Figure 1, a kind of BOPP production line energy-saving cooling device, comprise water chilling unit system, chilled water water pump 1 and chilled water cistern 2, described water chilling unit system 3 comprises handpiece Water Chilling Units 3-1, cooling water water pump 3-2 and cooling tower 3-3, described handpiece Water Chilling Units 3-1 is connected with extremely cold roller heat exchanger 5 and tank heat exchanger 6 by temperature valve 4, systemic circulation is generally: the heat exchanger directly chilled water being transported to the extremely cold roller of production line and tank after water chilling unit system 3 produces chilled water carries out heat exchange, manufacturing technique requirent is reached with the temperature controlling water in extremely cold roller and tank, low-temp cooling tower 7 and chilled water pump 8 are added in original basis on described chilled water cistern 2, the quantity of circulating water of described low-temp cooling tower 7 is 800 tons, the flow of described chilled water pump 8 is 800m3/h.
The more former chilled water of leaving water temperature due to low-temp cooling tower is high, heat transfer temperature difference is little, therefore production line chilling roller heat exchanger and tank heat exchanger need be increased, described low-temp cooling tower 7 and water chilling unit system 3 can work simultaneously, also can close water chilling unit system 3 completely, by low-temp cooling tower 7 system separately to production line cooling, can the electricity charge be saved like this, also low-temp cooling tower 7 can be closed, by cooling-water machine system 3 separately to production line cooling.
Wherein, the power of described handpiece Water Chilling Units 3-1 is 175KW, and the power of described chilled water pump 8 is 110KW.
To sum up, the utility model accomplishes the end in view.
