Abstract
The utility model discloses a condensed water recovery device after chemical heating of a drying cylinder of a paper machine. According to the utility model, the waste condensate water and heat are collected by modifying the original condensate water pipeline, so that the production cost is reduced, and the resource recycling rate is improved.
Description
Technical Field
The utility model relates to the technical field of papermaking equipment, in particular to a condensed water recovery device after chemical heating of a drying cylinder of a paper machine.
Background
In the production process of toilet paper, the use of the paper machine drying cylinder chemical such as MAP plays an important role in paper machine operation and product quality, in addition, the drying cylinder chemical temperature used by the paper machine large cylinder is usually 38 ℃, the chemical can exert the maximum effect at the temperature, the chemical is required to be heated by drying cylinder steam during the production at the present stage, and the heated condensed water is directly discharged into a trench, so that the water loss is caused, and the paper making ton paper cost is increased.
Disclosure of Invention
The utility model aims to: in order to overcome the defects of the background technology, the utility model discloses a condensed water recovery device after heating a chemical for a drying cylinder of a paper machine.
The technical scheme is as follows: the utility model discloses a condensed water recovery device after chemical heating of a paper machine dryer, wherein a steam pipeline is led to a chemical heating water tank of the dryer, and a condensed water pipeline is led out of the chemical heating water tank of the dryer and is connected with the chemical heating water tank of the paper machine.
Further, a filter is arranged on the condensed water pipeline.
Further, an electromagnetic flowmeter is arranged on the condensed water pipeline.
Further, a pipeline heater is arranged at the inlet of the condensed water pipeline positioned in the warm water tank of the paper machine.
Further, a temperature sensor is arranged on a pipeline positioned at the front part of the pipeline heater, and the temperature sensor is linked with the pipeline heater.
The beneficial effects are that: compared with the prior art, the utility model has the advantages that: the original condensed water pipeline is transformed, so that the waste condensed water and heat are collected, the production cost is reduced, and the resource recycling rate is improved; meanwhile, the pipeline heater meets the requirement of a warm water tank of the paper machine on the water temperature.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model.
Description of the embodiments
The technical scheme of the utility model is further described below with reference to the accompanying drawings and examples.
The condensed water recovery device after the chemical heating of the paper machine dryer is shown in fig. 1, a steam pipeline 1 is led to a chemical heating water tank 2 of the dryer, a condensed water pipeline 3 is led out from the chemical heating water tank 2 of the dryer and is connected with a warm water tank 4 of the paper machine, so that the condensed water lost after heating is recovered, and the consumption of heat and water is reduced.
The condensed water pipeline 3 is provided with a filter 5 and an electromagnetic flowmeter 6. The electromagnetic flowmeter 6 in the pipeline can play a role in metering the water quantity. The filter 5 can prevent impurities from entering the warm water tank and thus entering the paper machine clothing shower pipe, and the normal operation of the paper machine is affected.
Considering that the temperature of condensed water in winter is possibly low and does not meet the requirement of the warm water tank 4 of the paper machine, the condensed water pipeline 3 is provided with a pipeline heater 7 at the inlet of the warm water tank 4 of the paper machine, and a temperature sensor is arranged on a front pipeline of the pipeline heater 7 and is linked with the pipeline heater 7. When the water temperature to be fed into the warm water tank 4 of the paper machine is detected to be low, the pipeline heater 7 is automatically heated.
