Detailed Description

The features and principles of the present invention will be described in detail below with reference to the accompanying drawings, and the illustrated embodiments are only for explaining the present invention, and do not limit the scope of the present invention.

As shown in fig. 1, the utility model comprises a heater body, a tube box, tube plates, tube bundles and the like, wherein the tube box and the tube plates are arranged at the connecting section of the heater body, and the tube bundles are arranged between the two tube plates. In the heterogeneous heat medium heat exchanger, two heat media from different sources respectively enter mutually independent shell side channels of the heat exchanger through a steam inlet pipe to exchange heat with a pipe side medium, the heat medium A passes through the independent shell side channel A, and the heat medium B passes through the independent shell side channel B.

The shell side channel A comprises a plurality of sections which are communicated through a flow guide pipe A; the shell side passage B also comprises a plurality of sections which are communicated with each other through a flow guide pipe B. Taking fig. 1 as an example, steam enters from a steam inlet a and flows out through G1, G3 and a water outlet a, and another steam enters from a steam inlet B and flows out through G2, G4 and a water outlet B.

As shown in fig. 2 to 7, the sections of the shell-side passage a and the shell-side passage B are arranged at intervals, and the two kinds of steam are independently operated. That is, two media with different temperatures, pressures and sources enter the heater at the same time. The two media do not need to be mixed, respectively flow through different flow channels for heat exchange, and then flow out of the equipment through different pipelines. The flow guide pipes A of the sections of the shell-side channel A are arranged in a staggered mode, and the flow guide pipes B of the sections of the shell-side channel B are arranged in a staggered mode. The draft tubes A and B are arranged in a staggered manner. The design purpose of the design is to enable steam to fully flow and deflect in the shell-side channel A and the shell-side channel B, and improve the heat exchange efficiency of the steam.

The bottom of one side of the shell-side channel A, which is far away from the steam inlet pipe, corresponds to the water outlet A, and the bottom of one side of the shell-side channel B, which is far away from the steam inlet pipe, corresponds to the water outlet B. The inner side of the steam inlet pipe is provided with a baffle plate, and the universal baffle plate is used for preventing impact and guiding flow, so that the medium is fully diffused, and impact on the pipe bundle is avoided.

Two different heat sources enter the shell side of the heat exchanger at the same time, flow through different flow channels respectively, fully deflect the flow to heat a medium on the tube side, and then flow out of the equipment through different pipelines. The heterogeneous heat medium heat exchanger is a novel heat exchanger, can heat the medium of different sources simultaneously, compares with traditional indirect heating equipment, and it can heat up, cool down to two kinds of media simultaneously, and two equipment unite two into one, has not only saved the fund, has reduced the purchase, the installation of various pipeline instruments, greatly reduced the engineering degree of difficulty.
