The utility model content
In order to overcome the deficiency that existing plate type heat exchanger must stop and could clean, the utility model provides a kind of plate type heat exchanger that online backwash device is housed, and this plate type heat exchanger that online backwash device is housed can just can clean and blowdown not stopping.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of plate type heat exchanger that online backwash device is housed, comprise plate type heat exchanger, the primary fluid water inlet pipe is equipped with in the primary fluid import of heat exchanger, the primary fluid outlet pipe is equipped with in the primary fluid outlet, secondary heating agent water inlet pipe is equipped with in the import of secondary heating agent, secondary heating agent outlet pipe is equipped with in the outlet of secondary heating agent, it is characterized in that: block valve A is housed on the primary fluid water inlet pipe, block valve G is housed on the primary fluid outlet pipe, on the secondary heating agent water inlet pipe block valve J is housed, on the secondary heating agent outlet pipe block valve F is housed, block valve A is equipped with primary fluid backwash pipe water pipe outward on the primary fluid water inlet pipe, this pipeline other end connects the outlet of secondary heating agent, and block valve B is housed on the pipeline; Primary fluid backwash row of conduits water pipe is equipped with in the import of secondary heating agent, this pipeline other end is connected to outside the block valve G of primary fluid outlet pipe, block valve I is housed on the pipeline, secondary side blowoff valve and block valve K, secondary heating agent backwash row of conduits water pipe is equipped with in the primary fluid import, this pipeline other end is connected to outside the block valve F of secondary heating agent outlet pipe, block valve C is housed on the pipeline, primary side blowoff valve and block valve D, block valve J is equipped with secondary heating agent backwash pipe water pipe outward on the secondary heating agent water inlet pipe, this pipeline other end connects the primary fluid outlet, and block valve H is housed on the pipeline.
The using method that the plate type heat exchanger of online backwash device is housed is: A. closes block valve and the blowoff valve on all backwash pipelines; open the block valve on primary fluid inlet and outlet pipe lines and the secondary heating agent inlet and outlet pipe lines; the normal heat exchange of plate type heat exchanger; B. close the block valve on primary fluid inlet and outlet pipe lines and the secondary heating agent inlet and outlet pipe lines; open the block valve on all backwash pipelines; at this moment primary fluid water inlet enters the outlet of secondary heating agent through primary fluid backwash pipe water pipe; heat exchanging device secondary side carries out flowing out through primary fluid backwash row of conduits water pipe arrival primary fluid outlet pipe from the import of secondary heating agent after the backwash; as open the secondary side blowoff valve and close the dirt that block valve K can discharge secondary side; the water inlet of secondary heating agent enters the primary fluid outlet through secondary heating agent backwash pipe water pipe; heat exchanging device primary side carries out flowing out through secondary heating agent backwash row of conduits water pipe arrival secondary heating agent outlet pipe from the primary fluid import after the backwash, as opens the primary side blowoff valve and close the dirt that block valve D can discharge primary side.The backwash recovering step A condition that finishes returns to normal heat exchange state.
Because being provided with the backwash pipeline and the corresponding by-pass valve control that are communicated with heat exchanger primary side and secondary side has realized primary fluid is oppositely entered secondary side, the secondary heating agent is oppositely entered once survey, clean the on-line cleaning blowdown that also blowdown has realized plate type heat exchanger by the dirt that exists between adverse current heat exchanging device plate, can improve the operating efficiency of equipment, reduce and clean cost.
