Abstract
The utility model discloses a kind of vacuum water diversion system, it is characterized in that, including switch board, main vacuum water diversion mechanism and standby vacuum water diversion mechanism, both structures are identical, include the vacuum diversion volume that a top is provided with water inlet pipe, the top of vacuum diversion volume is connected by vacuum water diversion pipe with melt pit, and vacuum water diversion pot bottom connects outlet pipe by centrifugal pump.Centrifugal pump switch board calculates the inlet pressure of centrifugal pump according to the liquid level in gas pressure in working solution temperature, melt pit liquid level, water diversion tank, water diversion tank automatically, when result of calculation exceedes designated value, the standby centrifugal pump of automatic start, so as to ensure the stable operation of system.
Description
Technical field
A kind of production kraft paperboard vacuum water diversion system is the utility model is related to, is reclaimed automatically by vacuum water diversion system
The working solution of water-ring vacuum pump, belongs to pulp technology for making paper.
Background technology
When producing kraft paperboard, the inlet pressure of vacuum water diversion system centrifugal pump can be by working solution temperature, melt pit liquid
Position, gas pressure in water diversion tank, in water diversion tank liquid level influence, the stable operation of system can be influenceed when serious.
The content of the invention
Problem to be solved in the utility model is：In the inlet pressure production process of existing vacuum water diversion system centrifugal pump
Easily it is affected.
In order to solve the above problems, the technical solution of the utility model is to provide a kind of vacuum water diversion system, and its feature exists
In, including switch board, main vacuum water diversion mechanism and standby vacuum water diversion mechanism, both structures are identical, including a top
Vacuum diversion volume provided with water inlet pipe, the top of vacuum diversion volume are connected by vacuum water diversion pipe with melt pit, vacuum water diversion tank bottom
Portion connects outlet pipe by centrifugal pump.
Preferably, it is additionally provided with overflow pipe at the top of the vacuum diversion volume.
Centrifugal pump switch board according to the liquid level in gas pressure in working solution temperature, melt pit liquid level, water diversion tank, water diversion tank from
The dynamic inlet pressure for calculating centrifugal pump, when result of calculation exceedes designated value, the standby centrifugal pump of automatic start, so as to ensure to be
The stable operation of system.
Brief description of the drawings
Fig. 1 is the structural representation of vacuum water diversion system provided by the utility model.
Embodiment
To become apparent the utility model, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.
Embodiment
As shown in figure 1, for a kind of production kraft paperboard vacuum water diversion system provided by the utility model, it includes master
Vacuum water diversion mechanism and standby vacuum water diversion mechanism, the main vacuum water diversion mechanism include one top be provided with main water inlet tube 6 and
The main vacuum diversion volume 3 of main overflow pipe 7, the top of main vacuum diversion volume 3 are connected by main vacuum water diversion pipe 2 with melt pit 1, main true
The empty bottom of water diversion tank 3 connects primary flow pipe 5 by main centrifugal pump 4.The knot of standby vacuum water diversion mechanism and main vacuum water diversion mechanism
Structure is identical, including a top is provided with the standby vacuum diversion volume 9 of standby water inlet pipe 12 and standby overflow pipe 13, and standby vacuum is drawn
The top of water pot 9 is connected by standby vacuum water diversion pipe 8 with melt pit 1, and the standby bottom of vacuum diversion volume 9 passes through standby centrifugal pump 10
Connect standby outlet pipe 11.The top of main vacuum diversion volume 3 is provided with pressure sensor 1, and the bottom of main vacuum diversion volume 3 is set
There is pressure sensor 2 17, the middle part of main vacuum diversion volume 3 is provided with liquid level sensor 1.The top of standby vacuum diversion volume 9
Provided with pressure sensor 3 18, the bottom of standby vacuum diversion volume 9 is provided with pressure sensor 4 20, standby vacuum diversion volume 9
Middle part is provided with liquid level sensor 2 19.The bottom of melt pit 1 is provided with temperature sensor 21, and the bottom of melt pit 1 is provided with liquid level sensor
3 22.Pressure sensor 1, liquid level sensor 1, pressure sensor 2 17, pressure sensor 3 18, liquid level sensor two
19th, pressure sensor 4 20, temperature sensor 21, liquid level sensor 3 22 are by controlling cable 23 to be connected to switch board 14.
The course of work of the present utility model is：Main water inlet tube 6, standby water inlet pipe 12 are opened, it is main vacuum diversion volume 3, standby
Vacuum diversion volume 9 starts plus water, until main overflow pipe 7, the overflow of standby overflow pipe 13, now closes main water inlet tube 6, standby water inlet
Pipe 12, main overflow pipe 7, the upper switch valve of standby overflow pipe 13, open main centrifugal pump 4, and the main switch board 14 of centrifugal pump 4 starts simultaneously at fortune
OK, the main liquid level of vacuum diversion volume 3 starts to reduce, and main aqueduct 2 starts automatic feeding water, main vacuum water diversion after being reduced to certain liquid level
Mechanism starts stable operation, when the inlet pressure of main centrifugal pump 4 of the computing of switch board 14 sets pressure less than switch board 14, opens
Standby centrifugal pump 10 is opened, closes main centrifugal pump 4, enables standby vacuum water diversion mechanism, to ensure the continuous service of diversion system.Together
When, the switch valve on main water inlet tube 6 is opened, until main overflow pipe 7, the switch valve now closed on main water inlet tube 6.This practicality is new
Type, first according to local atmospheric pressure, working solution flow, melt pit liquid level, working solution temperature, confirms in kraft paperboard project
The size of water diversion tank；Then the centrifugal pump minimum entrance pressure under job requirement is determined according to necessary NPSH under centrifugal pump mark condition
Power, numerical value front pump switch board.
