Problems solved by technology
[0005] The purpose of the present invention is to provide a header shell pressure heat exchanger to solve the above-mentioned background technology, the existing header shell pressure heat exchanger is inconvenient to clean its inner cavity after a period of use It is easy to generate scale after being heated, and the existing heat exchanger does not have the filtering effect when in use, so impurities such as scale generated in the heat exchanger easily flow into the output pipe, causing the problem of blockage of the output pipe

The invention discloses a header shell body pressure-bearing heat exchanger. The header shell body pressure-bearing heat exchanger comprises a first header, heat exchange pipes and a second header, one end of the first header is fixedly connected with the heat exchange pipes, the plurality sets of heat exchange pipes are arranged, the other ends of the heat exchange pipes are fixedly connected with the second header, flushing inlet pipes are fixedly installed on one side of the first header, the plurality of sets of flushing inlet pipes are arranged, a connecting pipe is fixedly connected to one end of each flushing inlet pipe, a water pump is fixedly connected to the bottom of the connecting pipe, flushing outlet pipes are fixedly installed on one side of the second header, the plurality of sets of flushing outlet pipes are arranged, and one end of each flushing outlet pipe is in threaded connection with a sealing cap. According to the header shell body pressure-bearing heat exchanger, cleaning can be carried out on an inner cavity of the heat exchanger after the heat exchanger is used for a period of time, use is more convenient, meanwhile, water scale is easily generated after water is heated, filtering can be carried out on impurities in the water through a filter tank when hot water is discharged, and therefore the impurities such as the water scale generated in the heat exchanger are prevented from flowing into an output pipeline.
Description
technical field [0001] The invention relates to the technical field of heat exchange equipment, in particular to a header shell pressure heat exchanger. Background technique [0002] A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid, also known as a heat exchanger. Heat exchangers play an important role in chemical, petroleum, power, food and many other industrial productions. In chemical production, heat exchangers can be used as heaters, coolers, condensers, evaporators and reboilers, etc., and are widely used . For example, the PTFE heat exchanger for low temperature in power plants is a new device for waste heat recovery in power plants to reduce the exhaust gas temperature. The use of fluoroplastic heat exchangers can prevent acid corrosion and reduce the flue gas temperature to less than 100 degrees. Zhengzhou University of Technology successfully developed the polytetrafluoroethylene (referred to as F-4) tube-sheet limited-...
