When in use, primary heat media enter the secondary heat medium pipe, cold water is heated after mixing and cooling, individual arrangement of a steam boiler is avoided, production cost can be evidently reduced, since heat conducting oil is high in heating efficiency, leakage is avoided, heat utilization rate is high and energy sources can be saved, and further the device can be used for providing heat preservation hot water for saline solution in production of nylon66.
Description
Technical field
The utility model relates to the production unit of nylon 66, particularly the heat preservation hot water preparation apparatus of saline solution in the production of nylon 66.
Background technology
The saline solution that uses during the successive polymerization of nylon 66 is produced, to be incubated with 55 ℃, 65 ℃ hot water, at present, the preparation of this insulation hot water adopts steam boiler to be prepared, during preparation, utilize the water in the steam heating water tank, make water temperature reach service requirements, with pump hot water is extracted into then and makes use.This device needs to use steam boiler in the hot water preparation process, and the usage quantity of hot water and little, therefore, steam boiler of sole investment, its cost is higher.
At present, in the successive polymerization of nylon 66 was produced, the working temperature of reactor and polymerization reactor was all higher, and it need adopt thermal oil to heating such as polymerization reactors.
The utility model content
The purpose of this utility model provides the heat preservation hot water preparation apparatus of saline solution in a kind of nylon 66 productions, makes it can utilize the thermal oil in the production to produce 55 ℃, 65 ℃ hot water as primary fluid, to reach energy-conservation, reduces the purpose of investing simultaneously.
The purpose of this utility model is achieved in that the heat preservation hot water preparation apparatus of saline solution in nylon 66 productions, comprise hot well tank, hot well tank is provided with hot water outlet and water return outlet, described hot water outlet links to each other with the saline solution heat-insulation system through hot water circulating pump, rising pipe, and the backwater of saline solution heat-insulation system links to each other with water return outlet through return water pipe; Be provided with heat transfer tube in the described hot well tank, the import of heat transfer tube is connected heating agent pump outlet and import through the secondary heat medium pipe respectively with outlet, the secondary heat medium pipe of the on the suction side of heating agent pump is provided with a balancing segment, and the balancing segment two ends link to each other with the primary fluid outlet pipe with the primary fluid inlet pipe respectively.
When the utility model uses, the primary fluid inlet pipe links to each other with the heat-conducting oil system of primary fluid outlet pipe with the heated polymerizable reactive tank, the thermal oil that is full of same specification in the secondary heat medium pipe is made the secondary heating agent, thermal oil is under the heat medium circulation pump effect, enter from the heat transfer tube import, leave from the heat transfer tube outlet again, in hot well tank, cold water is heated to 55 ℃ that meet service requirements, 65 ℃ temperature, such hot water can be extracted out by hot water circulating pump and use, the backwater that turns cold after the use can be got back to the hot well tank from return water pipe, the secondary heating agent is in working cycle, can mix with the primary fluid that the primary fluid inlet pipe comes, reduce the temperature of primary fluid, the temperature of the secondary heating agent that raises simultaneously; Part secondary heating agent enters in the heat-conducting oil system of polymerization reaction trough through the primary fluid outlet pipe; Above-mentioned primary fluid and secondary heating agent can be changed mutually, enter the primary fluid that is in primary fluid inlet pipe and the primary fluid outlet pipe, enter in the secondary heat medium pipe for the secondary heating agent, the temperature of primary fluid is higher, unsuitable direct heating cold water, after adopting primary fluid and secondary heating agent to mix, can reduce the temperature of thermal oil, but make the cold water in its heat hot water tank.Compared with prior art, the beneficial effects of the utility model are: it need not to be provided with separately steam boiler, can obviously reduce production costs, because heating heat-conducting oil efficient height does not have and leaks heat utilization efficiency height, but save energy; This device can be used for providing insulation hot water to saline solution in the production of nylon 66.
Be the convenient automatic control that realizes water temperature, described hot well tank is provided with temperature difference transmitter, and the primary fluid outlet pipe is provided with the heating agent variable valve by temperature difference transmitter control aperture.The hot water temperature is lower than set(ting)value more for a long time in hot well tank, and the heating agent control valve opening strengthens, and impel the pyritous primary fluid to enter in the secondary heat medium pipe and mix, otherwise the heating agent control valve opening reduces even closes.
For ease of the water that supplement consumed is fallen, be connected with running water pipe on the described hot well tank, hot well tank is provided with water level transmitter, and running water pipe is provided with the entering water electromagnetic valve through water level transmitter control.Water level transmitter control entering water electromagnetic valve guarantees that the water level in the hot well tank is in standard state.
