System for monitoring reclamation of condensation water produced by papermaking

Abstract

The invention discloses a system for monitoring the reclamation of condensation water produced by papermaking, which comprises a water gauge, a DCS system, a motor-controlled cabinet and a motor, wherein the water gauge is arranged in a drainage tank; the water gauge is electrically connected with the DCS system, the DCS system is electrically connected with the motor-controlled cabinet, and the motor-controlled cabinet is electrically connected with the motor; the motor is arranged at a drainage pump; the drainage pump is communicated with the drainage tank; and the water gauge is provided with a warner for providing an alarm when the drainage tank achieves a high limit and a warner for providing an alarm when the drainage tank achieves a low limit. The system provided by the invention has the advantage that a system for automatically controlling and monitoring the water level of the drainage tank is added on the DCS control system, thereby overcoming the secondary waste of the condensation water in a condensation water reclamation system caused by that the capacity of the drainage tank is limited and the back water amount and the steam production amount of a boiler are imbalanced.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a papermaking condensation water recovery monitoring system. Background technique [0002] After a large amount of steam in paper-making enterprises completes heat exchange, a large amount of condensed water with a certain temperature is discharged to the ditch and ignored. The condensed water is clean and free of impurities, and there is a large amount of heat energy, so it is not economical to be discharged. . There are several problems in recycling papermaking condensate: 1. The collection system of condensate in each workshop is relatively complicated, and the reconstruction and construction workload is heavy; 2. Some equipment needs to be stopped for interface work, which affects production; 3. Water pumps are required in the recycling process Due to the limitation of energy-consuming parts and the capacity of the drain tank, some loss of condensed water will inevitably...

There are several problems in recycling papermaking condensate: 1. The collection system of condensate in each workshop is relatively complicated, and the reconstruction and construction workload is heavy; 2. Some equipment needs to be stopped for interface work, which affects production; 3. Water pumps are required in the recycling process Due to the limitation of energy-consuming components and the capacity of the drainage tank, it is inevitable that the condensed water will be lost in the recovery process. If it is not used properly, it may cause secondary waste.
