Description
Technical field
The present invention relates to central heating technical fields, more particularly to a kind of central heating method and system.
Background technique
With the popularization and application of power-saving technology, heating energy consumption intensity continuous declines, but due to northern cities and towns heating area
Increase and then heating energy consumption total amount is caused also to be increasing year by year.With the increase of heat supplying scale, the operating flux of heating network by
Year increases, and the conveying energy consumption of heating plant is caused to increase year by year.
During heat supplying scale development, pipe network flow is increasing, and index circuit is increasingly longer, and pipe network pressure drop is got over
Come bigger.It is general to concentrate in the case where heating network transformation is limited in order to adapt to central heating load increased needs year by year
Heat supply uses following three technical solutions: setting booster pump station, secondary booster is arranged in replacement heat-source Cycles water pump at user
Pump.
Shown in (a) as shown in figure 1, the method for replacement heat-source Cycles water pump be according to pipe network flow and change in pressure drop, every
Certain time limit replaces the water pump of a big flow, big lift.The influence to front end user is increased for ductwork pressure, using change
Regulating valve setting value or the method for the bigger resistance control valve of replacement solve front end user and cause asking for super flow because pressure difference increases
Topic.But the method for replacing heat-source Cycles water pump has the disadvantage in that one, the pressure increase of water supply line, to pipeline and equipment
Pressure-bearing brings problem, easily causes old equipment and pipe network to rupture, brings huge economic loss and influence heating effect.Two,
Increase close to the confession of the front end user of heat source, return water pressure difference, both increase restriction loss, the waterpower for also further deteriorating system is lost
It adjusts, so as to cause heating effect cold after preceding heat.Three, the investment of main heat source water pump replacement is high, since pump power increases, power supply
Capacity will also increase therewith.Four, operation energy consumption is high.
Shown in (b) as shown in figure 1, the method that booster pump station is arranged is that heat-source Cycles water pump is changed without, when pipe network pressure drop increases
Added-time, the method that the somewhere position between heat source and user increases relaying force (forcing) pump.Early period remains whole by heat-source Cycles water pump
The water of a pipe network recycles；Relaying force (forcing) pump is arranged in mid-term at A, and AB sections of pressure of supply water are increased on pressure of return water；Later period
BC sections of pressure of supply water are increased on pressure of return water by setting relaying at B.Before the method for the booster pump station of setting not will increase
The confession of end subscriber, return water pressure difference, to reduce the hydraulic misadjustment of user before booster pump station.But the method for the booster pump station being arranged
Have the disadvantage in that one, the setting of booster pump station needs to solve place and powerup issue, increases investment.Two, booster pump station away from
Heat source farther out, needs special messenger to carry out maintenance management, and increases operating cost.Three, relay pump forms pass of connecting with heat-source Cycles water pump
System, pressure working condition influence each other, and certain difficulty is brought to runing adjustment.
Shown in (c) as shown in figure 1, the method that secondary booster pump is arranged at user is that heat-source Cycles water pump is changed without, when
When pipe network pressure drop increases, the method for booster pump is set at user.Pressure of supply water is B at user B1, the pressure after user's use
It is reduced to B2, then by booster pump by boost in pressure to B3Enter water return pipeline afterwards；Pressure of supply water is C at user C1, used through user
Pressure reduction is to C afterwards2, then by booster pump by boost in pressure to C3Enter water return pipeline afterwards.Secondary booster pump is set at user
Method reduces a lot compared to the method operation energy consumption of the method for replacement heat-source Cycles water pump and setting booster pump station.But in user
There are still following disadvantages for the method for place's setting secondary booster pump: one, each user installation water circulating pump, initial cost is higher.Two, respectively
Water pump while parallel operation, can cause dynamic hydraulic equilibrium problem.Three, user's secondary booster pump lift far from heat source is excessive,
Cause terminal temperature difference pump power excessive.
Based on the above issues, the operating pressure of the pipeline of central heating how is reduced, investment for trnasforming urban land is reduced, reduces running cost
The technical issues of with this field urgent need to resolve is become.
