Abstract
The utility model discloses a kind of steam drum pressure stabilising arrangement, including drum, main steam line and lateral are connected with drum, lateral includes common steam pipeline and specific jet chimney, one gas relief line is set up on drum, gas relief line and specific vapour pipeline communication, gas relief line is provided with air relief valve.This utility model passes through to set up a gas relief line outside drum lateral, achievable gas relief line is not conflicted with the pressure of other laterals, and stable pressure can be provided, meet the lateral demand special to pressure requirements, the setting of air relief valve, the loss to equipment on special pipeline can be reduced, and take into account the pipeline differentiation excessively long pipeline infringement bringing simultaneously.
Description
Technical field
This utility model belongs to pressure vessel technology field and in particular to a kind of steam drum pressure stabilising arrangement.
Background technology
In grain and oil industry, typically by the way of multistage steam condensation and water ring pump pull negative pressure.Wherein, multistage steam
It is related to the stable of steam pressure or the multiplex situation of a steam drum.At present, existing Technology is that two-stage steam is cold
Solidifying include one-level water ring pump and pull vacuum, in order to prevent the long danger leading to water hammer occurs of jet chimney, using HP steam drum
Branch, wherein one pipeline rout does not need high steam, and high steam is using can cause technique to set after a period of time
Standby damage.
Some special production lines in Foodgrain and oilseed production, infringement pipeline being caused in order to avoid water hammer, an often vapour
Bag is multiplex, and some pipelines need specified pressure, if a drum uses for a plurality of pipeline, the pressure of pipeline is uncontrollable,
Especially individual tubes there are is specified pressure cannot meet Production requirement when requiring.For solve problem, from other low pressure pipelines
On change on this pipeline, but be often mingled with impurity because in other pipelines, and pipeline is long, pipeline water hammer effect is undesirable.
Content of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of steam drum pressure stabilising arrangement,
Pipeline will not be long, it can be avoided that water hammer causes damage, meets the pressure demand of a plurality of pipeline to pipeline simultaneously.
For achieving the above object, the technical solution adopted in the utility model is：A kind of steam drum pressure stabilising arrangement, bag
Include drum, drum is connected with main steam line and lateral, lateral includes common steam pipeline and specific steam pipe
Road, drum is set up a gas relief line, gas relief line and specific vapour pipeline communication, and gas relief line is provided with air relief valve.
Further, described main steam line and each lateral are provided with valve.
Further, described drum is also associated with drain water piping, and drain water piping is provided with drain valve, it can be avoided that in steam
The condensation flow carrying, to relatively more accurate equipment, prevents device damage.
Further, described drum bottom is provided with sewage draining exit, for discharging the dirt in drum.
Further, described drum connects a boiler, and the water in boiler is squeezed in drum by feed pump.Boiler and drum it
Between feedwater piping on be provided with water-supply valve, for adjust control enter drum hot water amount.
Further, at least 2, described common steam pipeline.
The beneficial effects of the utility model are：By setting up a gas relief line outside drum lateral, can achieve and subtract
Pressure pipeline is not conflicted with the pressure of other laterals, and can provide stable pressure, and it is special to pressure requirements to meet
Lateral demand, the setting of air relief valve, it is possible to reduce the loss to equipment on special pipeline, and take into account pipeline simultaneously and broke up
How the long pipeline bringing damages.
Brief description
Fig. 1 is structural representation of the present utility model.
In figure：1- drum, 2- main steam line, 3- main steam valve, 4- common steam pipeline, 5- common steam valve, 6- is special
Determine jet chimney, the specific steam valve of 7-, 8- gas relief line, 9- air relief valve, 10- drain valve, 11- drain water piping, 12- sewage draining exit,
13- water-supply valve, 14- feed pump, 15- boiler.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
As shown in the figure：A kind of steam drum pressure stabilising arrangement, including drum 1, drum 1 is connected with main steam line 2
And lateral, main steam line 2 is provided with main steam valve 3, and lateral includes common steam pipeline 4 and specific jet chimney
6, at least 2, common steam pipeline 4, common steam pipeline 4 is provided with common steam valve 5, and specific jet chimney 6 is provided with spy
Determine steam valve 7, described drum 1 is set up a gas relief line 8, gas relief line 8 is connected with specific steam pipe road 6, gas relief line 8 sets
There is air relief valve 9.
Described drum 1 is also associated with drain water piping 11, and drain water piping 11 is provided with drain valve 10, it can be avoided that in steam
The condensation flow carrying, to relatively more accurate equipment, prevents device damage.
Described drum 1 bottom is provided with sewage draining exit 12, for discharging the dirt in drum.
Described drum 1 connects a boiler 15, and the water in boiler 15 is squeezed in drum 1 by feed pump 14.Boiler 15 and vapour
It is provided with water-supply valve 13 on feedwater piping between bag 1, control, for adjusting, the hot water amount entering drum 1.
Gas relief line 8 is connected with specific jet chimney 6, closes specific steam valve 7, opens air relief valve 9 it becomes possible to meet special
Determine the steam pressure of jet chimney 6.When air relief valve goes wrong, gas relief line can be closed, open specific steam pipe simultaneously
Specific steam valve 7 on road 6, it can be avoided that keeping in repair during fault, being avoided that the tube side of pipeline is long again and leading to water hammer to occur.
The foregoing is only preferred embodiment of the present utility model, be not to restriction of the present utility model.This area
Change, remodeling, interpolation or replacement that those of ordinary skill is made in essential scope of the present utility model, also should belong to this reality
With new protection domain.
