Abstract
The invention discloses a plate heat exchanger equipped with an on-line backwashing device. The invention belongs to heat-exchange equipment and particularly relates to a plate heat exchanger equipped with a washing device. The plate heat exchanger equipped with the on-line backwashing device is provided with a backwashing pipeline for communicating the primary side and the secondary side of the heat exchanger and a corresponding control valve to ensure that the primary heating medium reversely enters the secondary side, the secondary heating medium reversely enters the primary side, dirt between plates of the heat exchanger is washed and discharged through the reverse flow and the on-line dirt washing and discharging of the plate heat exchanger are realized, so that the work efficiency of the equipment can be improved and the washing cost is reduced.
Description
Technical field
The invention belongs to heat transmission equipment, particularly with the plate type heat exchanger of cleaning device.
Background technology
Known plate type heat exchanger structure is to be assembled by fixed pressure plate, plate, top guide bar, support, fishbolt, movable pressure plate, lower guide rod, seal washer and flange-interface.But the mucous membrane that has many particles or liquid in equipment running process is attached to plate-type heat exchanger slab and causes the heat exchanger effect of plate type heat exchanger greatly to reduce.General plate type heat exchanger can move at equipment and cleans under the parking condition, blowdown, must stop to the plate type heat exchanger cleaning or changes plate type heat exchanger for subsequent use, has so virtually just increased the equipment general expenses and has wasted raw material.
Summary of the invention
The deficiency that must stop and could clean in order to overcome existing plate type heat exchanger the invention provides a kind of plate type heat exchanger that online back washing device is housed, and this plate type heat exchanger that online back washing device is housed can just can clean and blowdown not stopping.
The technical solution adopted for the present invention to solve the technical problems is: a kind of plate type heat exchanger that online back washing 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, the exterior once heating agent of block valve A backwash pipe water pipe on the primary fluid water inlet pipe, block valve B is equipped with in this pipeline other end connecting secondary heating agent outlet 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 second heat matchmaker 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 of the plate type heat exchanger of online back washing device is housed; it is characterized in that: 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; the block valve primary fluid water inlet of opening on all backwash pipelines enters the outlet of secondary heating agent through primary fluid backwash pipe water pipe; the heat exchanger 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; the heat exchanger 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 complete recovering step A condition of backwash 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 exchanger plate, can improve the operating efficiency of equipment, reduce and clean cost.
