Abstract
The utility model discloses a secondary net inlet pipe and outlet pipe bypass of a heat exchanger. The bypass comprises a second fluid inlet pipe of the heat exchanger, a second fluid outlet pipe of the heat exchanger, an inlet valve of a second fluid and an outlet valve of the second fluid, wherein the inlet valve and the outlet valve are connected to a position between an end plate of the heat exchanger and the inlet pipe and between the end plate of the heat exchanger and the outlet pipe respectively, the two ends of the bypass are communicated with the second fluid inlet pipe and the second fluid outlet pipe respectively, and the middle of a bypass pipe is provided with a control valve. Due to the secondary net inlet pipe and outlet pipe bypass, impurities in the second fluid can be filtered repeatedly in a circulating mode, a flow channel in a corrugated plate of the heat exchanger is not blocked, and work efficiency of the heat exchanger is guaranteed.
Description
Technical field
The utility model relates to the heat exchanger field, is specifically related to a kind of heat exchanger secondary network inlet/outlet pipe bypass.
Background technology
Heat exchanger is that the part heat of first fluid is passed to second fluid, makes the second fluid temperature reach the exchange heat equipment of technological process set quota.Heat exchanger secondary network fluid is that second fluid is mixed with impurity usually, while with the second fluid of impurity, in corrugated plate, carrying out heat exchange, easily causes the part of corrugated plate runner to be stopped up.Therefore existing heat exchanger is provided with filter on secondary network backwater main pipeline, can tentatively filter by the interior impurity of convection cell, but this filtration is disposable, filter effect is also not obvious, still have the runner that a little impurity stops up corrugated plate, affect the heat exchanger effectiveness of heat exchanger.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of heat exchanger secondary network inlet/outlet pipe bypass, can repeatedly filter cold fluid, guarantees the proper flow of second fluid in the corrugated plate runner, and then guarantees the operating efficiency of heat exchanger.
The utility model is achieved through the following technical solutions:
A kind of heat exchanger secondary network inlet/outlet pipe bypass, the second fluid that comprises heat exchanger is into and out of pipe and be connected to second fluid into and out of second fluid inlet valve and outlet valve on pipe, the two ends of bypass pipe be communicated in respectively second fluid into and out of pipe, described bypass pipe is provided with control valve.The further improvement project of the utility model is that the junction into and out of pipe of described bypass pipe and described second fluid lays respectively at the outside of described inlet valve, outlet valve.
The utility model further improvement project is, described bypass pipe two ends be welded on described second fluid on the tube wall of pipe.
The utility model compared with prior art has the following advantages:
The control valve of the utility model bypass pipe in normally off, does not affect the normal operation of heat exchanger when heat exchanger carries out fluid heat transfer.Within second fluid occurring during the too much situation of impurity, close advancing of second fluid, outlet valve, open the control valve of bypass pipe, fluid is under the effect of circulating pump, enter the secondary network main pipeline, flow into bypass pipe again from going out the pipe discharge at the inlet pipe from second fluid after once filtering, the fluid of discharging filters through the secondary network main pipeline under the effect of circulating pump again, discharge, so circulation, treat that contaminant filter is complete, close the control valve of bypass pipe and open advancing of second fluid, go out valve, the use of the present utility model impurity in the multiple times of filtration second fluid that can circulate, guarantee that the runner on the heat-exchanger ripple plate is not blocked, and then the operating efficiency of assurance heat exchanger.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
A kind of heat exchanger secondary network inlet/outlet pipe bypass as shown in Figure 1, the second fluid that comprises heat exchanger is into and out of pipe 2,3 and be connected to second fluid into and out of second fluid inlet valve 21 and outlet valve 22 on pipe, inlet valve 21 and outlet valve 22 other ends are connected on heat exchanger end plate 1, the two ends of bypass pipe 4 be communicated in respectively second fluid into and out of the pipe 2,3, its fixed form be welded on second fluid on pipe 2,3 tube wall, the middle part of bypass pipe 4 is provided with control valve 5.The junction into and out of pipe 2,3 of bypass pipe 4 and second fluid lays respectively at the outside of inlet valve 21, outlet valve 22, can guarantee that the runner on the heat-exchanger ripple plate is not blocked, and then guarantees the operating efficiency of heat exchanger.
