Description
Technical field
The utility model relates to a kind of heating plant.What be particularly related to is a kind of chain filling heating plant of multiinjector steam ejection for the drying cylinder of paper machine (cylinder group) heat supply.
Background technology
The steam heating device of existing paper machine many by directly and the heat exchanger (drying cylinder or cylinder group) that joins of high temperature and high pressure steam conveyance conduit and the drain valve that joins with heat exchanger exit and be connected to drain valve after the carbonated drink knockout drum constituted.The deficiency of this type of heating plant is the condensed water gap discharging of its drain valve, the condensate temperature height, the overall thermal efficiency that makes is not high, the low-grade steam that the carbonated drink knockout drum is discharged is failed to be used and just is discharged in the atmosphere, cause energy waste, condensate pump serious cavitation erosion simultaneously influences service life of condensate pump.
Except above-mentioned steam heating device, there are many paper machines to adopt steam ejection formula heating plant.This kind heating plant is divided into two big classes: one is simple steam ejector heat supply, the thermic load that it is characterized in that paper machine heat exchanger (drying cylinder or cylinder group) is all from steam ejector, its significant deficiency be can't adapt to paper machine well use the vapour load variations, depart from the design work scope of steam ejector easily; Another kind of steam ejection formula heating plant adopts the required pressure differential of steam ejector control condensed water continuous blow-down, use the filling pipeline simultaneously and comprise pressure sensor by an other cover, control valve and controller are used the vapour load variations what interior control loop adapted to paper machine.When steam ejection formula heating plant has guaranteed the required pressure differential of condensed water continuous blow-down, if the thermic load of heat exchanger (drying cylinder or cylinder group) changes, this filling controlling organization begins the additional quantity of steam of heat exchanging device (drying cylinder or cylinder group) to be regulated.The shortcoming of heating plant that the mode that this class adopts steam pressure to regulate (quality adjustings) is controlled the work of steam ejector is that system constitutes complexity, and employed steam ejector is the single injector formula steam ejector that has only a nozzle, and the thermal efficiency is not high.
The utility model content
The purpose of this utility model is the above-mentioned shortcoming that overcomes prior art, provides a kind of control simple, the chain filling heating plant of the multiinjector steam ejection that the thermal efficiency is higher.
The formation that realizes the chain filling heating plant of multiinjector steam ejection of the utility model purpose comprises the steam ejector that has a controlling organization that joins with the high temperature and high pressure steam conveyance conduit, be connected to the heat exchanger of the steam ejector port of export, the orifice plate steam trap that joins with heat exchanger exit, be connected to carbonated drink knockout drum behind the orifice plate steam trap and the filling pipeline that has a filling controlling organization that joins with steam ejector, the nozzle that it is characterized in that described steam ejector is made of central nozzle and a plurality of pilot jet of being located at around the central nozzle, and the controlling organization of described steam ejector is interactive chain the connection with the filling controlling organization.
The operation principle of the chain filling heating plant of this multiinjector steam ejection is as follows:
During work, exporting to heat exchanger (drying cylinder or cylinder group) from the steam of high temperature and high pressure steam conveyance conduit through the multiinjector steam ejector uses, the condensed water that produces enters the carbonated drink knockout drum by the orifice plate steam trap and carries out flash distillation, the indirect steam that produces from condensed water is aspirated by the multiinjector steam ejector, reenters heat exchanger (drying cylinder or cylinder group).When the thermic load of heat exchanger (drying cylinder or cylinder group) changes, the amount of corresponding indirect steam is also changing, therefore, this heating plant carries out chain setting with the adjusting control and the filling controlling organization of the central nozzle of steam ejector, when regulating the air inflow of central nozzle, the controlling organization of handling steam ejector also handles the tonifying Qi controlling organization, thereby the soakage of control and regulation secondary steam, guaranteed that steam ejector is operated on the operating point of design, guaranteed the suction and the required pressure differential of condensed water discharging of indirect steam.The core of this heating plant is the multiinjector steam ejector.Different with the single injector steam ejector, the multiinjector steam ejector therein heart nozzle around be provided with a plurality of pilot jets, these pilot jets can increase the power steam that penetrates at a high speed from nozzle and by the contact range of the indirect steam of injection, to being carried out elementary injection by the indirect steam of injection, raising is by the indirect steam flow velocity of main burner injection, thus the thermal efficiency of raising steam ejector.
The adjusting controlling organization of described steam ejector can be that Direct Travel is regulated controlling organization.Regulate controlling organization by this Direct Travel the Direct Travel piston type that central nozzle carries out is regulated, regulate the steam flow that enters nozzle by moving of piston, this adjusting has guaranteed to enter the steam pressure of nozzle, has further improved the thermal efficiency of steam ejector.
The adjusting controlling organization of described steam ejector can also be an angle stroke adjustment controlling organization.Angle stroke adjustment controlling organization is the governor motion by a similar tee ball valve, converts the circular motion of spool the rectilinear motion of piston to by a transmission mechanism, reaches and Direct Travel is regulated the similar function of controlling organization.
Compared with the aforementioned existing similar products, the utility model has the advantages that to change the single injector steam ejector into the multiinjector steam ejector that the thermal efficiency by pilot jet raising steam ejector makes the thermal efficiency of this heating plant can improve 10%-20%.The control of filling control and steam ejector is combined, simplified the control of whole system.Alternative existing single injector formula heating plant uses.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.
