FRP cool tower defense technology and new progress fiberglass ice cold, but the tower is a portfolio of diversified domestic cooling tower frozen winter run a major problem exists. Located in cold areas, whether it is the introduction of overseas cooling towers, still design their own domestic cooling tower construction are serious phenomenon in the cold winter operation, has yet to come up with a complete solution. Toyo Ishikawajima-Harima Heavy 30000m3 / h cross-flow wet cooling tower in the late seventies with the introduction of Daqing ethylene joint chemical plant in China. Daqing area located at latitude 45 ° 5 '~ 47 °, with an average annual temperature, etc. 3.3 ℃, freezing of more than five months, the harsh climatic conditions to learn to run the cooling tower winter brings difficult. Although Ishikawajima-Harima Heavy cooling tower design considerations of the anti-icing problem, but running on a frozen practice confirmed the existence of the problem resolutely. China chemical engineering general corporate Cangzhou Chemical packing plant cooling tower cooling tower according to the status quo, joining the plant transformation Laota Jinian accumulated experience and anti-icing technology, cooling tower proposed new anti-icing program transformation, after the implementation of the plot from 2003 to 2005 annual winter run, anti-icing effect superficial. 1 Status Daqing Petrochemical Enterprises cooling tower circulating water cooling tower steam plant is limited to cross-flow type mist wet cooling towers, two points, a total of five ten. Plane dimensions: 64.05m × 20.13m, tower 14.662m (not covered by the sink edge duct height), the tower is wood frame structure, as CCA preservative handle. Tricking filler mixed with packing technology, equipped with high efficiency thin film filler and filler bit arch, equipped principle summarized as follows: In the arrangement of vertical wave frame packing film composition layer to the near side of the blinds, single film fill diameter measured depth of 0.915 m, the rest of the dome with a diameter deep filler, or water using multi-wave dual function or water, the collection of water, high speed, drag slightly dense type water collection is arranged in the upper part of the tower, drag the smaller type sparse collection of water arranged in the lower part of the tower and medium-sized water collection is arranged in the middle of the tower, and configure the FRP plate hydraulic conductivity in water collection device, to avoid the formation of secondary float in water. 2, the technical proposal first circulating water cooling tower is wet wood crossflow cooling towers, entered the cold, severe freeze on cooling towers, so the tower structure, blinds, side layer packing serious damage. Need to invest a lot of money each year, human service and protection, which is one of the main protective measures have been adopted in the form of reverse fan forced to solve the problem of cooling tower winter freeze, the effect of the ice is good, but also to accelerate the payment of the fan device destroyed price. In order to solve the cold winter cooling tower serious problem, approval and enterprise technology research plot at all relevant departments, to August 24, 2003 at the start of a cycle 6 # -10 # tower 1-6 shutters installed unless the top ∮60 × 3.5UPVC plastic sprinkler pipe, sprinkler pipe spacing processing on a ∮7mm water hole every 50mm, creating a large area of ??water curtain to burn off the winter ice formation. 3, renovation construction and operation of all of the tasks completed by the design and construction of Cangzhou Chemical packing plant cooling tower. From August 24, 2003 construction start, ending on November 23, 2003 all of the ice pipe installation tasks. Because of funding problems, no top eight layers of ice pipe installation. As of the end of February 2004 a total of 2352 hours of operation, the entire tower variable process parameters are to meet the design requirements, and obtain the results summarized as follows. After installation of the ice tubes, circulating water temperature difference increases equalization, equalization of the temperature difference between the water supply this year is 8.35 ℃, with the same period last year increased equalization dwarf 4.63 ℃, which indicates that the air circulation, a significant increase in the cooling rate, and enhance the circulating water temperature macro-control ability. Viewing from the outside cooling tower, cooling tower on cold winter state reached up to fundamentally improve, blinds basically not on cold, reach and ice tube design requirements. After installation of the ice tube, because the blinds are not on the basic freeze, therefore, East Tower Fan Fan winter is not reversed, saving energy, in line with the project requirements, and dwarf the same period in 2002, saving electricity for: 180KW × 10h × 100 天 × 5 sets × 85% = 765000 KW · h, equivalent to nearly 267,800 yuan RMB people. (Note: to save power = a wind turbine power earlier reversal × 2002 the total annual number of days × × fan power factor = 3600 KW · h) because the winter fan does not reverse the negative impact of impairment reversal on the fan of the device, the fan flakes destruction frequency ring gear reduction and other devices, extending the fan device causative cycle, according to the fan once the initiation of reverse faults Equal number of counts, and ice tube put into use to avoid CT-001 tower fan foil ring destroyed two start / year Gear Fault 1 start / year, and in 2002 dwarf, inspection and maintenance expense savings of 2 × 1600 + 1 × 40000 = 4.32 million. Winter fan reverse, because the vapor pressure increases, the heat circulating water vapor entrained accelerated outward drift of the ice after the tube is put into use, detract from the drift, drift to curb the influence of water on the cooling tower surrounded background detracts tower outside the frozen degree and outdoor facilities, erosion; and because the amount of impairment on the tower frozen, so that the cooling tower shape with greatly improved, the presence of background for this year's work laid the foundation for the rule set. Of ice tube put into use, so the larger the winter ice formed on the cooling tower for safety hazards resulting from the basic membership and eliminate production, increase the safety factor of the cooling tower operation, cooling tower make safer operation and reliable inspection staff, Indirect benefits are superficial. 4. Conclusion In summary, the effect of the ice tube is relatively superficial. It is put into use, basically solved the case of the northern winter on a unique cooling tower severe cold, an increase of cooling tower itself running reliability, improved cooling tower operating conditions, reduce the consumption of fan injuries devices, extending the fan causative life, so that the cooling tower operation safer ride.
