Abstract
The utility model relates to a classification heating apparatus, which comprises heat exchangers of all levels and steam-water separation tanks that are arranged between the steam outlets of the previous level heat exchangers and the steam inlets of the next level heat exchangers. The steam inlet of the first level heat exchanger is provided with a steam ejector. Each level steam-water separation tank respectively is provided with a pressure controller and a liquid level controller; the pressure controller is arranged at the steam inlet; the outlet of the liquid level controller is connected with the next level steam-water separation tank; the steam outlet of the last lever steam-water separation tank is connected to the suction end of the steam ejector. The apparatus is especially suitable for replacing the existing classification heating apparatus of paperboard.
Description
The utility model relates to a kind of graded supply device.What be particularly related to is a kind of stagewise steam heating device of the cylinder group heat supply for paper machine.
The steam heating device of existing paper machine system with high temperature and high pressure steam directly send into I level cylinder group, condensed water after heat exchange is put into the carbonated drink knockout drum through a drain valve, after flash distillation, form flash steam and supply with the next stage drying cylinder and use.For guaranteeing the requirement of upper level drying cylinder to temperature and pressure, its drain valve is an intermittently starting, makes that the condensed water in the upper level drying cylinder can not be discharged continuously, is unfavorable for the high efficiency drying of paper; And the dilatation flash steam of depending merely on condensed water intermittently also can't satisfy the demand of next stage drying cylinder preferably.In addition, open and also make the drying cylinder decompression when drain valve discharges water, cause meaningless loss.The 3rd, the low-grade steam that its final stage drying cylinder is discharged is not used and is just exported by condensate pump, makes cavitation (in serious, causes the wasting of resources simultaneously yet, makes the complete machine thermal efficiency not high.
The purpose of this utility model is the above-mentioned shortcoming that overcomes prior art, but the injection type steam graded supply device of a kind of continuous drainage, efficient energy-saving is provided.
The formation that realizes the injection type steam graded supply device of the utility model purpose comprise heat exchangers at different levels and be located at upper level heat exchanger steam (vapor) outlet and next stage heat exchanger steam inlet between the carbonated drink knockout drum, end is provided with a steam ejector in the steam inlet of first order heat exchanger, described carbonated drink knockout drum at different levels is respectively equipped with a pressure controller and a fluid level controller, wherein, pressure controller is located at the steam inlet end, the outlet of fluid level controller connects subordinate's carbonated drink knockout drum, and the steam (vapor) outlet of the carbonated drink knockout drum of bundle level and the suction side of described steam ejector join.
Operation principle of the present utility model is as follows:
High temperature and high pressure steam enters the condensed water and the surplus vapour of discharging after finishing heat exchange in the first order heat exchanger through injector and enters the carbonated drink knockout drum, condensed water dilatation flash distillation, discharge water vapour, under the control of pressure controller, enter II level heat exchanger, condensed water and the surplus vapour finished after the heat exchange of II level enter in the carbonated drink knockout drum of II level, the condensed water of I level also enters by fluid level controller in the carbonated drink knockout drum of II level simultaneously, condensed water dilatation flash distillation in jar, and temperature further reduces.Valve steam enters in the III level heat exchanger and carries out heat exchange under the control of the pressure controller of II level, so up to the last grade heat exchanger.Flash steam in the steam-water separator of the last grade is utilized again by steam ejector suction, and remaining cryogenic condensation water is sent boiler or other water place back to by water pump.Thereby finish the purpose of classification continuous heat supply.
Still can give carbonated drink knockout drums at different levels be provided with one with high temperature and high pressure steam input pipe and the pressure controller that connects, when the load flash steam big, upper level of II level, III level heat exchanger can not satisfy its needs, can utilize this pressure controller directly to replenish initial steam from trunk line.
Consider that device heat changes the variation of lotus, can a pressure controller be set, to replenish its load-bearing capacity to steam ejector.
The utility model is compared with traditional graded supply device, has avoided the use drain valve, utilizes hydraulic controller and pressure-control valve to realize continuous drainage, has increased the heat exchange efficiency of heat exchanger.The low-grade steam of the last grade also in addition make full use of, improved the effective rate of utilization of heat energy, simultaneously the temperature of condensed water is minimized, can prevent the cavitation erosion of condensate pump effectively, the graded supply device of alternative existing paper machine uses.
Provide embodiment below in conjunction with accompanying drawing.
Fig. 1 structural representation of the present utility model
What as shown in Figure 1, present embodiment provided is the structural representation of three grades of heating plants.Wherein, 2 for being installed in the steam ejector on the high temperature and high pressure steam person in charge 1,3 has been the pressure controller of the ability to work of additional injector 2,4,5,6 be respectively I, II, III level heat exchanger, 10,11,12 steam-water separators that are respectively I, II, III level heat exchanger, 7,8,9 for being located at the pressure controller of each steam-water separator steam inlet end, and 13,14,15 is fluid level controller.16 is condensate pump.Meeting the high temperature and high pressure steam supply injector 2 that design pressure requires, when the steam consumption of follow-up load heat exchanger changes, is not that part is replenished by pressure controller 3, makes the pressure stability that enters I level heat exchanger 4.The condensed water and the surplus vapour of discharging from I level heat exchanger 4 enter carbonated drink knockout drum 10, and condensed water dilatation flash distillation discharges water vapour, enters II level heat exchanger 5 under the control of pressure controller 7.Condensed water after the heat exchange and surplus vapour enter III level carbonated drink knockout drum 11, the condensed water of the carbonated drink knockout drum 10 of I level also enters II level carbonated drink knockout drum 11 by its fluid level control device 13 simultaneously, low-grade flash steam after the flash distillation in the supply III level heat exchanger 6 III level carbonated drink knockout drums 12 and surplus vapour reenter the heat supply circulation after being compressed by injector 2 suctions, make the temperature of the condensed water in the carbonated drink knockout drum 12 be able to further reduction simultaneously, send boiler or other water place back to by water pump 16.The liquid level that fluid level control device 15 guarantees in the carbonated drink knockout drum 12.
Consider the change of the load in II, the III level heater, can between II, III level carbonated drink knockout drum and high temperature and high pressure steam input are responsible for 1, connect a pressure controller 17,18, directly to replenish steam.
