Description
Technical field
The present invention relates to central heating technical field, more particularly to a kind of central heating method and system.
Background technology
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 causes the conveying energy consumption of heating plant to increase year by year.
During heat supplying scale develops, 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：Heat-source Cycles water pump is replaced, booster pump station is set, secondary booster is set at user
Pump.
As shown in (a) in Fig. 1, replace heat-source Cycles water pump method be according to pipe network flow and change in pressure drop, every
Certain time limit replaces a big flow, the water pump of big lift.The influence to front end user is raised for ductwork pressure, using change
Regulating valve setting value or the method for replacement bigger resistance control valve solve front end user and cause asking for super flow due to pressure difference increases
Topic.But the method for replacing heat-source Cycles water pump has the following disadvantages：One, the pressure of water supply line increases, to pipeline and equipment
Pressure-bearing brings problem, and old equipment and pipe network is easily caused to rupture, huge economic loss is brought and influences heating effect.Two,
Confession, the increase of return water pressure difference close to the front end user of heat source, both add 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 that main heat source water pump is replaced is high, since pump power increases, power supply
Capacity will also increase therewith.Four, operation energy consumption is high.
As shown in (b) in Fig. 1, the method for setting booster pump station 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 Xun Huan of a pipe network；Mid-term sets relaying force (forcing) pump at A, and AB sections of pressure of supply water are increased on pressure of return water；Later stage
Set relaying that BC sections of pressure of supply water are increased on pressure of return water at B.Before the method for the booster pump station of setting will not increase
The confession of end subscriber, return water pressure difference, so as to reduce the hydraulic misadjustment of user before booster pump station.But the method for the booster pump station set
It has the following disadvantages：One, the setting of booster pump station needs to solve place and powerup issue, adds investment.2nd, booster pump station away from
Heat source increases operating cost farther out, it is necessary to special messenger carries out maintenance management.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.
As shown in (c) in Fig. 1, the method that secondary booster pump is set at user is that heat-source Cycles water pump is changed without, when
During pipe network pressure drop increase, the method for setting booster pump 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 drop is down 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 is compared to the method for replacing heat-source Cycles water pump and the method operation energy consumption of booster pump station is set to reduce very much.But in user
There are still following shortcomings 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 away from heat source is excessive,
Cause terminal temperature difference pump power excessive.
Based on the above problem, 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 as this field urgent need to resolve.

The comprehensive response time is determined between seasonable；Each user is finally determined according to each subscriber response time and the comprehensive response time
For heated succession.The present invention determines each user according to each subscriber response time for heated succession, and then reduces the pipeline of central heating
Operating pressure, reduce investment for trnasforming urban land, reduce operating cost.
The present invention proposes the concept of response time, using neural network algorithm according to each user's secondary side supply water temperature data
The response time of each user is determined with return water temperature data, on the premise of heating effect is not influenced, according to the response of each user
Time realizes wheel sequence heat supply.
The present invention switches the user of real-time heat supply using wheel sequence, and under conditions of sequence heat supply is taken turns, the quantity of circulating water of pipe network is small,
Conveying energy consumption is low, has important energy-saving effect.
The present invention determines maximum heating demand according to the parameter of the heat-source Cycles water pump, so that it is determined that once adding in wheel sequence
User quantity, and do not have in this, as operating flux, at heat source to replace water circulating pump, add in the user of wheel sort run not yet
Hydraulic misadjustment can occur.
Embodiment five
1 each technical solution of table compares
For the central heating system of general scale, 10,000,000 m of area of heat-supply service2Relatively conventional, pipe network maximum length approaches
15km.Separately below the quality of each technical solution is analyzed in the method for technology one, technology two, technology three and the present invention.
Heating index takes 45W/m2, then heating demand is 450MW.It is calculated by 130 DEG C/70 DEG C of confession, backwater temperature difference, then system
Circular flow be 6450t/h.It is calculated by the optimal specific frictional head loss of 50Pa/m, the circulation resistance of pipe network is 150m.
The comparison of each technical solution is shown in Table 1.Pump efficiency is calculated by 90%, and run time was calculated by 120 days.
