It enters the inside of blow-off pipe 15 and is discharged by blow-off pipe 15, the scale removal reagent used herein is rust remover, can be led to
It crosses reagent and enters the inside that pipe 9 enters cleaning 8 into injection.
The hot water being discharged at hot water out pipe 3 does not have heterochromatic, and the sewage being discharged at cold water outlet pipe 5 is with after heterochromatic,
Then judgement is the rust deposite of the outer surface appearance of condenser pipe 7, then scale removal flow is as follows：Start micromotor 12 by control panel,
The working method of micromotor 12 is positive and negative periodic rotation, and micromotor 12 can drive 13 turns of threaded rod after starting
It is dynamic, when threaded rod 13 is rotated since the nut 22 on lifter plate 141 can not be rotated, lifter plate can be driven
141 are lifted, and when lifter plate 141 is lifted, the snaking wire 142 on lifter plate 141 can be with the appearance of condenser pipe 7
Face rubs, to remove the rust deposite of 7 outer surface of condenser pipe, until in the water that cold water outlet pipe 5 goes out exclusion without heterochromatic, then
Judge that derusting is clean, derusting work is completed.
In summary：The utility model provides a kind of heat exchanger facilitating scale removal, which passes through descaling device 14
The rust deposite that 7 outer surface of condenser pipe can be removed influences the feelings of condensation effect to avoid the generation of condenser pipe 7 heat conduction efficiency low
Condition occurs, and the chemical reagent cleared up inside tank 8 can be chemically reacted with the dirt inside condenser pipe 7, to cold
The inner wall of solidifying pipe 7 carries out the work of scale removal, and condenser pipe 7 is avoided to block, while being also avoided that the rust deposite that the inside of condenser pipe 7 occurs
It is attached on the inner wall of condenser pipe 7, influences the efficiency of condenser pipe heat transfer, improve the thermal conductivity of condenser pipe, while also increasing
The service life of heat exchanger.
