Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
The utility model discloses the degassed cooling circulating water cooling system of a kind of viscose glue, comprise the mixing condenser, steam jet pump, chilled water tank, DCS control system, auxiliary condenser and the plate type heat exchanger that use in temperature reduction technology process.
Connect flow chart and see Fig. 1, mixing condenser is communicated with degassing drum, and auxiliary condenser is connected with steam jet pump and mixing condenser, and utilize cooling water and steam heat-exchanging moment condensation to carry out degassed process to deaerator viscose glue, the high-temperature water of generation collects chilled water tank.DCS control system is positioned at control room.
The water return pipeline of the degassed generation high-temperature water of viscose glue installs heat exchange of heat pipe additional, this heat exchange of heat pipe is divided into evaporation ends and condensation end, steam cooling water enters auxiliary condenser, auxiliary condenser is arranged on high-temperature water water return pipeline, and the other end of high-temperature water water return pipeline is connected with the evaporation ends of heat exchange of heat pipe.Low-voltage variable frequency centrifugal blower is positioned at outdoor mounted on outdoor cold wind pipeline, and outdoor cold wind pipeline is connected with the condensation end of heat exchange of heat pipe.Blower fan adopts the low-voltage variable frequency centrifugal blower of 18000-25000CMH, and this low-voltage variable frequency centrifugal blower is that the cold wind crosswind machine mouth of heat exchange of heat pipe blows cold wind.The below that water collecting tank is positioned at heat exchange of heat pipe communicates with heat exchange of heat pipe, mixing condenser.Mixing condenser is connected with plate type heat exchanger, is connected with viscose glue degassing drum.DCS system is positioned at control room, automatically controls cold blast rate according to required water temperature.
Heat exchange of heat pipe is made up of heat pipe 1, bobbin carriage, liquid-sucking core and end cap.It utilizes sweat cooling, and make heat pipe two ends temperature difference very large, heat is conducted fast, and hot biography mode adopts convect h, and its heat transfer is fast, and turnover mode is shown in Fig. 2.Heat pipe 1 is arranged in bobbin carriage, and low-voltage variable frequency centrifugal blower 2 is arranged in low temperature wind pipeline 3 and is positioned at outdoor, and low temperature wind pipeline 3 is connected with the condensation end of heat exchange of heat pipe.The overboard pipeline 4 of high temperature is communicated with the evaporation ends of heat exchange of heat pipe.High temperature air channel 5 is communicated with heat exchange of heat pipe, and the hot blast of heat exchange of heat pipe is introduced heating of house.Sub-cooled water lines 6 communicates with water collecting tank.
