Description
Technical field
The utility model relates to a kind of two effect vapour and coagulates water sugar content on-line monitoring device.
Background technology
Sugar refinery boiler is gone into Lu Shui and is mainly derived from qualified water after exhaust steam vapour coagulates water and former water softening, adopts former water to go into the additional water source of stove water as boiler, and the operating cost of boiler is higher, also is unfavorable for water-saving and emission-reducing.It is the good complement water source that boiler is gone into stove water that the two effect vapour that evaporation section produces coagulate water, and it contains micro sugar, and temperature reaches about 105 ℃.Utilize two effect vapour to coagulate water and replace former water reuse boiler, this will reduce the operating cost of boiler greatly, reclaim heat energy simultaneously, significantly reduce to take former water and externally discharged waste water, lay a good foundation for Closed Circulation in Sugar Production realizes " zero water intaking ".At present, sugar refinery all adopts the big drop in the juice catching device interception juice vapour to realize to the removal that two effect vapour coagulate the contained micro sugar of water, because the undulatory property of vacuum and evaporation capacity during evaporation, juice catching device catch juice efficient with instability, so coagulating water, two effect vapour contain also instability of sugar, generally between 25-200mg/L.Height contains two of sugar and imitates vapour and coagulate water and should not cover boiler, because going into stove water, sugar refinery boiler constantly circulates, wherein organic sugar and inorganic salinity are constantly accumulated, in the course of time, the normal use of boiler will be influenced, particularly sugar enters in the pot and can oxidation generate organic acid, and the pH value of stove water is descended, and brings adverse influence; The sugar of coking becomes carbon compound, flows with steam, is deposited in the metal pipe-wall, brings harm to equipment.Therefore, to boiler long-time running summary of experience, imitate vapour and coagulate the water sugar content and surpass 50mg/L when two by industry, can not as pressure be 2.45MPa boiler replenish stove water.
At present, sugar refinery adopts artificial regularly chemical examination to monitor that two effect vapour coagulate the contained micro sugar of water, sometimes misoperation, cause that two effect vapour coagulate water and seriously are with sugar to enter boiler, even cause the accident, injure boiler safety, operation efficiently, therefore, two effect vapour coagulate the on-line monitoring of water sugar content just becomes the insoluble always technical barrier in sugar refinery.
Summary of the invention
Utilize two to imitate vapour and coagulate water and replace former water reuse boiler in order to solve, can guarantee the problem of boiler safety, efficient operation again, the utility model provides a kind of two effect vapour to coagulate water sugar content on-line monitoring device, but this device not only in-service monitoring two is imitated the sugar content that vapour coagulates water, also may command two is imitated vapour and is coagulated whether reuse boiler of water, imitate sugar content that vapour coagulate water when surpassing setting value when two, automatically close two and imitate vapour and coagulate water and enter the valve of boiler feed water case and open the valve that enters the process heat water tank, give the alarm prompting simultaneously.
The utility model is achieved in that two effect vapour coagulate water sugar content on-line monitoring device and are installed on the two effect vapour condensate lines, comprises sampling in-service monitoring pipeline, advances boiler feed water case pipeline, advances process heat water tank pipeline.Be characterized in: sampling in-service monitoring pipeline, advance boiler feed water case pipeline, advance process heat water tank pipeline and all imitate the vapour condensate lines and be connected in parallel with two, sample valve, two is set on the sampling in-service monitoring pipeline imitates vapour and coagulate hydrocooler, two and imitate vapour and coagulate water sugar content on-line monitoring instrument, the pipeline outlet accesses the sample feeder; Advance to be provided with on the boiler feed water case pipeline maintenance shut-off valve, autocontrol valve, the pipeline outlet connects the boiler feed water case; Advance to be provided with on the process heat water tank pipeline maintenance shut-off valve, autocontrol valve, the pipeline outlet connects the process heat water tank.
Above-described two imitate vapour coagulates hydrocooler and adopts indirect heat exchanger, is used for cooling down high-temperature two to imitate vapour and coagulate water.
Above-described two imitate vapour coagulates water sugar content on-line monitoring instrument employing conductivity monitor or dissolved solid content monitor, is used for monitoring that two imitate the sugar content that vapour coagulate water, because of its sugar content and dissolved solid content existence relation.
Above-described autocontrol valve adopts motorized valve or pneumatic valve, and its can be opened or close after receiving instruction, is used for controlling two and imitates the switching that vapour coagulate water sugar content pipeline when exceeding standard.
The utility model has the advantages that:
1. in-service monitoring: in normal running, can imitate the sugar content that vapour coagulate water by in-service monitoring two.
2. in time switch: imitate vapour and coagulate the water sugar content when exceeding standard when two, close two automatically and imitate vapour and coagulate water and enter the valve of boiler feed water case and open the valve that enters the process heat water tank, give the alarm prompting simultaneously.
3. reliable operation: this device technique maturation, simple in structure, reliable operation.
4. easy for installation: this device is installed in two and imitates on the vapour condensate line, and quantities is few, is convenient to install.
Description of drawings
Fig. 1 is the structural representation that two effect vapour of the present utility model coagulate water sugar content on-line monitoring device.
As shown in Figure 1, the solidifying water sugar content on-line monitoring device of two effect vapour is made up of sample valve 2, the solidifying water cooler 3 of two effect vapour, the solidifying water sugar content on-line monitoring instrument 4 of two effect vapour, maintenance shut off valve 6, autocontrol valve 7, maintenance shut off valve 9, autocontrol valve 10, sampling in-service monitoring pipeline 1, advances boiler feedwater case pipeline 5, advances process heat water tank pipeline 8 and all be connected in parallel with two effect vapour condensate lines 0.
Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated.
Can see in the structural representation of the present utility model as shown in Figure 1, when two effect vapour coagulate the work of water sugar content on-line monitoring device, sample valve 2 scalable stopple coupon flows, two effect vapour coagulate hydrocooler 3 two effect vapour are coagulated water cooling to normal temperature, can accurately measure the sugar content that two effect vapour coagulate water so that two effect vapour coagulate water sugar content on-line monitoring instrument 4.Two effect vapour coagulate water sugar content on-line monitoring instrument 4 can set the upper and lower bound that two effect vapour coagulate the water sugar content, just close autocontrol valve 7 when arriving higher limit, forbid that two effect vapour coagulate water and enter the boiler feed water case, open autocontrol valve 10 simultaneously, allow two effect vapour coagulate water and enter the process heat water tank, and give the alarm prompting simultaneously, when being returned to lower limit, just open autocontrol valve 7 immediately and close autocontrol valve 10, close the alarm prompting simultaneously, recover two effect vapour and coagulate the operation that water enters the boiler feed water case.Standard-sized sheet during maintenance shut-off valve 6,9 operate as normal is just closed when the pipeline emergency maintenance.
