Description
Technical field
The present invention relates to cleaning device, relate in particular to blast furnace slag quenching water on-line cleaner of heat exchanger.
Background technology
Along with energy shortage is more and more serious; the utilization of secondary energy sources is more and more important; the blast furnace slag quenching water waste heat recovery of steel plant is more and more extensive; but in flushing cinder water, also have a large amount of dregs; after working long hours for the heat exchanger of heat exchange, can fouling stop up; current cleaning method and device need heat exchanger to carry out shutdown operation mostly, have a strong impact on the operating efficiency of heat exchanger.
Summary of the invention
The present invention aims to provide a kind of blast furnace slag quenching water on-line cleaner of heat exchanger, the object of cleaning, not affecting heat exchanger operating efficiency to reach heat exchanger limit working edge.
For achieving the above object, the present invention realizes by following technical proposals.
Blast furnace slag quenching water on-line cleaner of heat exchanger, is comprised of storage spherical tank, Rubber ball pump and supporting pipeline, valve.In storage spherical tank, have a baffle plate, this baffle plate is controlled by baffle plate handle, for controlling the transmitting-receiving of bead; The flushing cinder water oral siphon of heat exchanger connects service valve by lateral, the service valve other end connects Rubber ball pump and storage spherical tank successively, the pipeline of the storage spherical tank other end produces branch, connecting respectively forward receives Ball valve and oppositely receives Ball valve, forward is received Ball valve and all by lateral, is connected the flushing cinder water outlet pipe of heat exchanger with the reverse Ball valve of receiving, in flushing cinder water outlet pipe, have a ball screen, for reclaiming bead, this ball screen is controlled forward and reverse by ball screen handle.
Blast furnace slag quenching water on-line cleaner of heat exchanger provided by the invention, for the obstruction of flushing cinder water heat exchanger and the problem of stop cleaning heat exchanger, utilize bead with flushing cinder water, to enter together the heat exchanger tube of heat exchanger, souring heat exchanger by bead reciprocating collision heat exchanger tube and flushing cinder water exchange heat pipe carries out on-line cleaning, solved the problem of heat exchanger stop cleaning, heat exchanger operating efficiency and using exhaust heat of slag flushing water organic efficiency have been improved, and the ball screen of cleaning device of the present invention can overturn back and forth under the control of ball screen handle, by the positive and negative reciprocating collision of bead and ball screen, reduce the obstruction of ball screen, increased self-cleaning function, service life and the operating efficiency of cleaning device have been strengthened.
Accompanying drawing explanation

Shown in figure: 1, heat exchanger; 2, flushing cinder water outlet pipe; 3, ball screen; 4, ball screen handle; 51, forward is received Ball valve; 52, oppositely receive Ball valve; 6, storage spherical tank; 7, bead; 8, baffle plate handle; 9, baffle plate; 10, Rubber ball pump; 11, service valve; 12, flushing cinder water oral siphon.
The specific embodiment
Below in conjunction with drawings and Examples, the present invention is described in detail.
As shown in Figure 1, blast furnace slag quenching water on-line cleaner of heat exchanger, is comprised of storage spherical tank 6, Rubber ball pump 10 and supporting pipeline, valve.In storage spherical tank 6, have a baffle plate 9, this baffle plate 9 is controlled by baffle plate handle 8, for controlling the transmitting-receiving of bead 7; The flushing cinder water oral siphon 12 of heat exchanger connects service valve 11 by lateral, service valve 11 other ends connect Rubber ball pump 10 and storage spherical tank 6 successively, the pipeline of storage spherical tank 6 other ends produces branch, connecting respectively forward receives Ball valve 51 and oppositely receives Ball valve 52, forward is received Ball valve 51 and all by lateral, is connected the flushing cinder water outlet pipe 2 of heat exchanger with the reverse Ball valve 52 of receiving, in flushing cinder water outlet pipe 2, there is a ball screen 3, be used for reclaiming bead 7, this ball screen 3 is controlled forward and reverse by ball screen handle 4.
The cleaning process of blast furnace slag quenching water on-line cleaner of heat exchanger: the baffle plate handle 8 in storage spherical tank 6 is rotated, baffle plate 9 is by laterally transferring to longitudinally, bead 7 in storage spherical tank 6 flows out, and enter Rubber ball pump 10 pressurizations by pipeline, service valve 11 is opened, after pressurization, bead 7 enters flushing cinder water oral siphon 12 through service valve 11 and lateral, along with flushing cinder water enters the heat exchanger tube of heat exchanger, bead 7 is reciprocating collision in the heat exchanger tube of heat exchanger, heat exchanger tube is washing away of process flushing cinder water again, and the dirt being attached in heat exchanger tube is cleaned totally; The flushing cinder water that cleaning bead 7 is later followed after heat exchange enters flushing cinder water outlet pipe 2, as shown in Figure 1, when ball screen handle 4 forwards are controlled ball screen 3, forward receipts Ball valve 51 is opened, is oppositely received Ball valve 52 and closes, bead 7 is received Ball valve 51 and pipeline by forward, gets back to storage spherical tank 6; As shown in Figure 2, when ball screen handle 4 is oppositely controlled ball screen 3, oppositely receive that Ball valve 52 is opened, forward is received Ball valve 51 and closed, bead 7, by oppositely receiving Ball valve 52 and pipeline, is got back to storage spherical tank 6; Baffle plate handle 8 in storage spherical tank 6 is rotated, and baffle plate 9 is by longitudinally transferring to laterally, and bead 7 is stayed in storage spherical tank 6.
Blast furnace slag quenching water on-line cleaner of heat exchanger is in cleaning process, and ball screen 3 is upset back and forth under the control of ball screen handle 4, and the positive and negative reciprocating collision by bead 7 with ball screen 3 reduces the obstruction of ball screen 3.
