Client needs to provide the operating parameter of heat exchange station, including the ginseng such as quantity of steam, cooling water inflow and heat exchange station area first
Number, the parameter that supplier provides according to client carry out lectotype selection.Equipment is transported to erecting bed after the completion of type selecting.
In-site installation only need the utility model being placed in heat exchange room it is fixed on level ground, then connect water route and
Circuit can come into operation.
Cooling water channel is connected first.Cooling water enters from water inlet pipe 33 in the circulation line, by back-washing dirt separator
Enter the first water tank 32 after A5.Back-washing dirt separator A5 can filter out the bulky grain thing in cooling water, be deposited in the first water tank 32
A certain amount of cooling water is contained to meet the need of work of cooling water pump 31.
Cooling water pump 31 extracts cooling water from the first water tank 32 and is sent to the second water tank 34, and band cooling water is full of the
Plate heat exchanger 21 is entered back into after two water tanks 34.Wherein the first water tank 32 and the second water tank 34 play the work of storage cooling water
With, its act on be prevent cooling water it is unexpected stop or increment consumption causes in plate heat exchanger 21 because cooling water reduces and
It is damaged.
Cooling water is flowed out from the cooling water output terminal of plate heat exchanger 21, and heat exchange station is being eventually returned to after return pipe 35
In interior water tank, then enter the utility model from water inlet pipe 33 again.
After cooling water channel connection, heat exchange water route is connected, which is to protect plate heat exchanger 21, prevent high temperature from steaming
When vapour enters plate heat exchanger 21, cooling water also underfill plate heat exchanger 21, causes the heat exchange thin plate in plate heat exchanger 21
Deformation even damages after receiving high temperature.
High-temperature steam enters the utility model by steam inlet pipe 41, then in turn through back-washing dirt separator B6, relief valve
7th, boiler is returned to after connecting tube 42, plate heat exchanger 21, heat-exchanging water tank 43 and condenser pipe 44.High-temperature steam is in back-washing dirt separator
During B6, back-washing dirt separator B6 can filter out the large particulate matter in high-temperature steam, reduce the possibility of 21 fouling of plate heat exchanger.
Relief valve 7 can monitor the pressure of high-temperature steam at any time, and when detection pressure reaches threshold value, relief valve 7 acts, and part high temperature steams
Vapour is discharged by the bypass of relief valve 7, and manifold pressure declines, and ensures the safety of operation.
High-temperature steam carries out heat exchange in plate heat exchanger 21 with cooling water, and high-temperature steam heat release liquefaction is condensation
Water, is then discharged from the heat exchange output terminal of plate heat exchanger 21.Enter heat-exchanging water tank 43 after condensed water discharge and in heat-exchanging water tank
Accumulation in 43, condensed water is returned along condenser pipe 44 under the promotion of subsequent high temperature steam pressure after heat-exchanging water tank 43 is filled
Boiler.
The effect of small pump 8 is that cooling water inflow is replenished in time.After the dosage of cooling water rises or is consumed, small pump
8 start, and water is supplemented in cooling water channel, is prevented because cooling water inflow deficiency causes the damage or user's heat supply of plate heat exchanger 21
The problems such as indoor temperature caused by amount deficiency declines.
The plate heat exchanger 21, cooling water pump 31 and small pump 8 of the utility model are both provided with two sets.In normal operation
In, it is a set of in running order, it is another set of to be in stand-by state.When first set because failure can not work or overhaul of the equipments
When, operating personnel can start another set of in time, ensure the normal work of heat exchange station.At the same time ought wherein a set of operation a period of time
Afterwards, it is readily modified as another set of operation.Such two complete equipment is used alternatingly, and can extend its service life, reduces what failure occurred
Probability, extends the service life of equipment.
Embodiment described above is only the preferred embodiment of the utility model, and the not feasible implementation of the utility model
It is exhaustive.For persons skilled in the art, it is done on the premise of without departing substantially from the utility model principle and spirit
Any obvious change gone out, should all be contemplated as falling with the claims of the utility model.
