    Ingenious use of low temperature heat to replace the heat sourceIngenious use of low temperature heat to replace the heat source

    On the morning of November 18th , Feng Xiongwei, deputy director of the Second Industrial Zone of the Second Chemical Industry Department, was checking the operation of the thermal water system.


    On the morning of November 18th , Feng Xiongwei, deputy director of the Second Industrial Zone of the Second Chemical Industry Department, was checking the operation of the thermal water system.


    Since last year, the Ministry has organized technical backbones to deeply tap the energy-saving potential of the device.


    Plant heat medium water from 1 since early put into use, has been running smoothly 11 months, effective protection of the relevant device for heat demand.

    The medium-pressure steam produced by the No.


    They also conducted special training for team samplers, clarified sampling precautions, and ensured that everyone passed the test.


    In addition, they found in daily inspections that the surface of the refrigerant water heat exchanger of the installation often appears condensate in a high-temperature environment, causing a waste of cold sources.


    In view of this, the Ministry immediately decided to pack heat preservation treatment on the outer surface of the 5 refrigerant water heat exchangers, and adjust the circulating water consumption in the device in time according to changes in ambient temperature, which can reduce the circulating water by more than 200,000 tons per month .

    "The condensate recovery rate of the two sets of devices increased by 1 percentage point year-on-year.

    Since the launch of the continuous efforts to create benefits, the department has continuously explored rules and adjusted and improved methods around the maximum reuse of condensate, and continued to optimize and eliminate bottlenecks.


    The Ministry deeply optimized the operation mode of the condensate system, strengthened communication with relevant upstream units, and adjusted the flow between the condensed water in the water and steam work area and the jelly bus and storage tanks to ensure that the temperature of the same type of incoming water is similar, and to avoid the excessive temperature difference of the incoming water from causing water hammer.


    In view of the problem of no spare mixed bed in the No.
    3 condensate system, this section refines the operation method.
    Before the mixed bed fails to regenerate, the level of the condensate tank is appropriately controlled, the regeneration method is optimized, and the regeneration time is shortened.
    Due to the poor resistance to fluctuations of the No.
    1 condensate system, it is easy to contaminate the entire system when the incoming water fluctuates greatly, which not only increases the maintenance cost, but also increases the water consumption of the device.
    In view of this, the Ministry decisively discontinued the No.
    1 condensate system, and through careful operation to ensure that the No.
    2 and No.
    3 systems with a high degree of automation and strong impact resistance operate in a long period of high load.

    According to statistics, in the first 11 months of this year , the two sets of devices processed and recovered a total of 3.
    251 million tons of condensate , an increase of 19,000 tons over the same period last year .
    This not only replaced the demineralized water and saved more than 23 million yuan, but also reduced operating costs due to the deactivation of the No.
