Abstract
A papermaking condensation water recovery monitoring system comprises a water gauge, a DCS (data communication system), a motor control box and a motor, wherein the water gauge arranged on a drain tank is electrically connected to the DCS, the DCS is electrically connected to the motor control box, the motor control box is electrically connected to the motor, and the motor is mounted on a drain pump. Besides, the drain pump is communicated with the drain tank; the water gauge is provided with an alarm for giving out alarm when the drain tank reaches a high limit; and the water gauge is further provided with another alarm for giving out alarm when the drain tank reaches a low limit. By additionally arranging an automatic drain tank water level control and monitor system on the DCS, the papermaking condensation water recovery monitoring system overcomes secondary waste caused by the problems of capacity limitation of the drain tank and unbalance between water return quantity and boiler duty in a condensation water recovery system.
Description
Technical field
The utility model relates to pulp technology for making paper, particularly relates to the papermaking condensate water and reclaims supervisory system.
Background technology
After a large amount of steam are finished heat interchange in the paper enterprise, produce that a large amount of condensate water that has uniform temperature is discharged into trench and out in the cold, the clean inclusion-free of this condensate water water quality, and also have a large amount of heat energy, be discharged very uneconomical.Reclaim the papermaking condensate water and have following problem: 1. the collection system of each workshop condensate water is comparatively complicated, and the rebuilding construction workload is big; 2. the interface work equipment component of need stopping using, influence is produced; 3. need to use power consumption such as water pump parts in the removal process, and the restriction of capacity such as drain tank, condensate water has some losses unavoidably in recovery, be not good at if utilize, and may cause the secondary waste on the contrary.
Summary of the invention
The purpose of this utility model is to avoid weak point of the prior art and provides a kind of papermaking condensate water to reclaim supervisory system.
The purpose of this utility model realizes by following technical measures.
The papermaking condensate water reclaims supervisory system, comprise the water level gauge, DCS system, motor control box and the motor that are arranged at drain tank, described water level gauge is electrically connected on described DCS system, and described DCS system is electrically connected on described motor control box, and described motor control box is electrically connected on described motor.
Described motor is installed on drainage pump.
Described drainage pump is communicated with described drain tank.
Described water level gauge is provided with drain tank and reaches the high alarm that gives the alarm in limited time.
Described water level gauge is provided with the alarm that gives the alarm when drain tank reaches lower bound.
The utility model sets up drain tank water level control and surveillance automatically in DCS control, having overcome in the condensate return system secondary that the imbalance problem because of drain tank capacity limit and backwater amount and boiler duty causes wastes.
Description of drawings
Utilize accompanying drawing that the utility model is described further, but the content in the accompanying drawing does not constitute any restriction of the present utility model.
Fig. 1 is the system schematic that papermaking condensate water of the present utility model reclaims an embodiment of supervisory system.
Embodiment
The utility model is described in further detail with the following Examples.
An embodiment of papermaking condensate water recovery supervisory system of the present utility model as shown in Figure 1, comprise the water level gauge, DCS system (dcs), motor control box and the motor that are arranged at drain tank, described water level gauge is electrically connected on described DCS system, described DCS system is electrically connected on described motor control box, and described motor control box is electrically connected on described motor.
Described motor is installed on drainage pump.
Described drainage pump is communicated with described drain tank.
Described water level gauge is provided with drain tank and reaches the high alarm that gives the alarm in limited time.
Described water level gauge is provided with the alarm that gives the alarm when drain tank reaches the lower bound water level.
Prescribe a time limit when the drain tank water level reaches height, DCS sends and starts the drainage pump instruction, and the water of drain tank is squeezed into oxygen-eliminating device.When the drain tank water level arrived lower bound, DCS sent and stops the instruction of drainage pump motor, stops the drainage pump operation, to reach the purpose of keeping the drain tank water level balance.
Should be noted that at last; above embodiment only is used to the technical solution of the utility model is described but not to the restriction of the utility model protection domain; although the utility model has been done detailed description with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can make amendment or be equal to replacement the technical solution of the utility model, and not break away from the essence and the scope of technical solutions of the utility model.
