Low Pressure Boiler In Textile Industry


Low Pressure Boiler In Textile Industry

Boiler Plant softened water pollution to identify the type of low pressure boiler in textile industry plants soften water pollution type of identification to identify the type of pollution to a comprehensive raw water quality, the design parameters, pollution index, running records, equipment performance indicators and Microbial be judged: ⑴ colloidal contamination: contamination occurred colloid when, usually accompanied by the following two characteristics: A, pretreatment microfilter clogging quickly, especially pressure increases rapidly, B, SDI value is usually 2.5 or more. ⑵ microbial contamination: microbial contamination occurs, the RO water through the apparatus and total number of bacteria concentrated water are high, usually have no maintenance and sterilization as required. ⑶ boiler calcium scale: can be adjusted depending on the raw water quality and design parameters. Of water in terms of carbonate, if recovery of 75%, adding the designed inhibitors, the LSI concentrate should be less than 1; LSI concentrate without scale inhibitor should be less than zero, typically It does not produce calcium scale. ⑷ available 1/4 inch plastic PVC pipe insertion component performance changes in different parts of the test assembly is determined. ⑸ determines the type of contamination of the change device performance. ⑹ available acid (such as citric acid, dilute of HNO3), and the cleaning effect The cleaning liquid is determined limescale, the cleaning liquid composition is further confirmed by analysis. ⑺ liquid cleaning chemical analysis: Take the raw water, cleaning liquid, cleaning liquid, three sample analysis.

2, Kai hot water low pressure boiler in textile industry furnace operation

When Kai furnace again, should open the circulating pump, the water in the system to achieve the normal cycle, open the induced draft fan, blower, start the grate and the coal system, gradually recovered coal combustion. When the shutdown longer required pressure furnace, combustion should preferably seam, after clearing slag, then covered with a thick coal seam fire pressure.

Coal-fired low pressure boiler in textile industry to carry out a comprehensive investigation and remediation work, Luohe City, Henan Province, Li Jizhen provincial, city and town each environmental supervision departments centralized call the relevant personnel, three-pronged approach to work.

First, a comprehensive investigation to find out the base.

Li Jizhen town for all industrial enterprises, restaurants, vermicelli processing plants, farms and other coal-fired boiler with a boiler units diagnostic investigation, the establishment of coal-fired boilers ledger, so base-clear, the situation is clear.

Second, clear standards, conducting pressure.

Town leaders organized the renovation work conference of coal-fired boilers, the boiler so that the user's overall reform and the dismantling of scheduling, the town must be eliminated in the formation of boiler upgrade, you do not need to be removed out of shutting down consensus.

Third, actively coordinate, and assign responsibilities.

Natural gas is being implemented in conjunction with the "double substitution", and actively coordinate the gas boiler equipment suppliers in collaboration with the local gas company, entered into a collaboration, timely completion of "substitution of gas for coal" upgrade tasks.

As of now, the town has shut down six coal-fired boilers, the implementation of "substitution of gas for coal" boiler upgrade eight, effectively promote the prevention and control of air pollution.

Second, the principle of determining the number of low pressure boiler in textile industry units

The maximum heat load calculating the number of operating principles shall all boilers operating at rated power of the boiler can be satisfied is determined.
