Abstract
The utility model relates to the field of chemical fiber equipment and especially discloses a flow pipeline of an EG tubular type heat exchanger used for dredging blockage of a circular EG tank inflow pipeline. An EG inlet main pipe is connected with the circular EG tank inflow pipeline and a heat exchanger inlet pipe. The heat exchanger inlet pipe is connected with a main heat exchanger and a spare heat exchanger. The circular EG tank inflow pipeline is connected with a circular EG tank. The end, close to the circular EG tank, of the circular EG tank inflow pipe is connected with a spare pipeline. The spare pipeline is connected with the main heat exchanger and the spare heat exchanger via three-way joints. The flow pipeline of the EG tubular type heat exchanger has following beneficial effects: when the circular EG tank inflow pipeline blocks, a main valve and a first valve can be opened and EG flows into the circular EG tank via the spare pipeline so that the circular EG tank inflow pipeline is dredged during operation process of equipment; and due to small diameter of the spare pipeline and high control precision of valves, the heat changer is effectively prevented from fluctuating caused by over-quick filling operation.
Description
Technical field
The utility model relates to chemical fiber machinery field, especially a kind of circulation duct of EG tubular heat exchanger.
Background technology
In the circulation duct of existing EG tubular heat exchanger, EG is by EG intake header, and a part is re-used as spray EG after sending into heat exchanger, and a part flows directly into circulation EG tank.From practical operation situation, when switching EG tubular heat exchanger, filling standby heat exchanger, fluctuate larger, and circulation EG tank flow ipe is stifled sometimes, needs dredging, needs complete equipment out of service.By analysis, when the reason that causes larger fluctuation phenomenon is filling, heat exchanger inlet pipeline diameter is larger, and the valve on heat exchanger inlet pipeline is larger, and large valve control accuracy is low, thereby causes filling too fast, finally causes fluctuation.
Utility model content
The purpose of this utility model is that a kind of circulation duct of the EG tubular heat exchanger that can dredge under running status when circulation EG tank flow ipe stops up is provided in order to solve the deficiency of above-mentioned technology.
In order to achieve the above object, the circulation duct of the EG tubular heat exchanger that the utility model is designed, it comprises EG intake header, circulation EG tank flow ipe, heat exchanger inlet pipeline, main heat exchanger and standby heat exchanger, EG intake header is connected with heat exchanger inlet pipeline with circulation EG tank flow ipe respectively, heat exchanger inlet pipeline is connected with standby heat exchanger with main heat exchanger respectively, circulation EG tank flow ipe is connected with circulation EG tank, on circulation EG tank flow ipe, near circulation EG tank end, be connected with backup line, backup line is connected with standby heat exchanger with main heat exchanger respectively by three-way interface, on backup line, near circulation EG tank flow ipe place, be provided with main valve, on backup line, near main heat exchanger place, be provided with the first valve, on backup line, near standby heat exchanger place, be provided with the second valve.
For fear of when switching EG tubular heat exchanger, filling standby heat exchanger, produce larger fluctuation, the sectional area of backup line is less than respectively the sectional area of circulation EG tank flow ipe, heat exchanger inlet pipeline.
In order to be further controlled at, switch EG tubular heat exchanger, while filling standby heat exchanger, the larger fluctuation of generation, main valve, the first valve and the second valve are high accuracy by-pass valve control.
The circulation duct of the resulting EG tubular heat exchanger of the utility model, when circulation EG tank flow ipe occurs to stop up, can open main valve and the first valve, EG can flow into circulation EG tank by backup line, can when equipment moves, to circulation EG tank flow ipe, dredge, simultaneously when switching EG tubular heat exchanger, filling standby heat exchanger, because backup line diameter is little, valve control accuracy is high, can effectively avoid filling fluctuation too fast and that produce, thereby make production stability good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
