To effectively and efficiently solve air quality problems, further improve people's quality of ambient air, Luliang city government issued the "Luliang city and surrounding tackling air pollution control action plan."

Luliang within the range of 1300 square kilometers around the city, "an area three counties' area under the jurisdiction of section: Lishi District, Riverside street nine township (town, street) a total of 54 villages; Luo Zhongyang County town of 12 gold villages; Liulin County, Lee Wan total of four villages; Fangshan County Dawu town a total of 11 villages.

1, the effective promotion of clean heating. Implementation of the "Clean Luliang city in northern winter heating pilot cities embodiments (2018-2020 years)" to determine the progress of the task, 2018-2019 before the end of September totaled clean heating transformation of rural areas 90000 (including within the scope of "no coal zone" rural households), where: Lishi District, 20000, 15000 Fangshan County, Zhongyang County 15000, 40000 Liulin County.

2, bulk coal coal strengthen supervision. Downtown "ban on coal zone" expanded to 88 square kilometers, the Willows, in the sun "and ban on coal zone" for the county built-up areas and the surrounding area 5 km, Fang Shan range "ban on coal zone" for the built-up area region, 2019 August 31, coal stoves and coal "double clear" within the scope of "no coal zone" implementation. "No coal zone" outside the prohibited than 1% sulfur, 16% ash content than coal for civilian. Determine civil bulk coal sales to crack down on low-quality coal sales practices.

3, to carry out comprehensive improvement of the boiler. 2019 August 31, all workers in the region (companies) industry, commerce, services, basic administrative units out of 10 steam tons / hour and coal-fired boilers, combustion zone ban (ban on coal zone) all residents within the range, all the villagers self-built coal-fired boilers out of the cell. Not "ban on coal zone" to be able to ensure clean winter heating, self-built coal-fired boilers shall be eliminated; it is difficult to ensure clean winter heating, self-built coal-fired boilers Always use clean coal substitute. And more than 65 tons of steam coal-fired boilers to complete the transformation of energy-saving and ultra-low emissions, low nitrogen gas boiler basically completed the transformation, to achieve ultra-low emissions coal-fired power plants. 35-65 tons of steam coal-fired boilers and more particularly to achieve stable discharge standards; co-firing biomass boilers ban coal and other fuels, efficient dust bags and other ancillary facilities. Non-alcohol-based fuels to burn in the name of blended chemical waste.

Experts for you to order: a rice boilermercial induction rice boiler chemical cleaning process, the purpose of chemical cleaning chemical cleaning is the main method to reduce boiler corrosion effects, by using the method of chemical vapor boiler system in a variety of sediment, metal oxides and other impurities, and forming a metal surface protective film. It is due to reduce corrosion of boiler heating surface structures and sedimentary deposits caused by poor thermal and moisture contamination, an important measure to ensure that the boiler safe and stable operation of the economy. Second, the range of chemical cleaning of a newly installed boiler (either direct current or a furnace drum furnace). 2, has been running the boiler. 1) drum boiler, the boiler water system of a general cleaning of the body only. 2) only the DC furnace cleaning and high pressure water system of a boiler heater. Third, the chemical cleaning of boiler chemical cleaning mode and flow two ways soaking, flow of the cleaning is frequently used, can be divided into flows for all kinds of furnace cleaning cycle cleaning method, cleaning method for DC open boiler and dosing or the use of the cleaning liquid directly into the outfall EDTA complexing low pressure natural circulation boiler cleaning. Fourth, the chemical cleaning process step of the general process rinse water system, the transition boiling alkali, alkaline wash water rinsing, pickling, rinsing water after pickling, rinsing and passivation. 1. water washing new boiler system, the water must be flushed during chemical cleaning. Clarified water or industrial water filtration period after rinsing is available, the flushing flow rate is generally 0.5 ~ 1.5m / s. Rinse with water to reach the end of a transparent and free of impurities prevail. Its purpose is to remove the internal pipe corrosion products and other impurities and some deposits generated during operation. Meanwhile, the case of smooth and tight loops whereby the inspection system may, in particular, parallel tube rows arranged in the vertical, if the phenomenon will affect the quality of the gas plug. Also not to participate there will be more severe acid corrosion when cleaning part can not be filled with liquid protection. 2. The caustic soda boiling or soda boiling embodiment only the new boiler, the furnace in the boiling process, the sewage from the bottom need 2 to 3 times, changing the water after cooking a lot furnace. The concentration of water to be discharged close to the boiler water and normal, and the Ph value dropped to about 9, the temperature dropped to 70 ~ 80 ℃, to discharge all the water. After boiling out of boiler internal inspection cope, the metal surface requires no rust and corrosion products, and the passivation film to complete the formation. Deposited on the drum should also be clear, dirt etc. header. Caustic after degreasing acid washing, or cleaning cycle should be generally and soaking cycles combined. After clarification by filtration caustic water, demineralized water, or in addition to brine, washing water to Ph≤8.4, quality transparent. If the sulfate scale, high silicate content, to improve the cleaning effect, the transformation may be performed before alkali cooking acid. Effect of water washing after acid pickling and pickling is 3. deposits on the metal wall into the insoluble salts or soluble complexes, dissolved in the cleaning solution, then when the waste liquid discharge drain. Cleaning solution must strictly control the temperature of the pickling solution during the pickling, cycle rate, the acid level of the groove drum and the like, and recorded hourly examination cycle time, record truthfully problems. When the cleaning cycle each circuit to a predetermined time, and measuring the concentration of the acid concentration of iron ions should be strengthened. When each circuit in the pickling solution ferric ion concentration and acid concentration and stable balance, pickling is expected to end, the detection tube can be removed to check the cleaning effect, when the inner pipe is still dirt to be monitored in the pipe system Replacing continue cleaning to clean the monitoring pipe, the circulation should IH, stopped before pickling. Activated metal surface to prevent secondary rust, at the end of pickling acid should not be used directly by the process of emptying the flushing water on again, a purity of greater than 97% of the available continuous ejection nitrogen waste acid, may also be desalinated when the flow rate of ejection waste acid, the acid using variable flow ejection flushing water, flushing water flow rate should be cleaned to achieve more than doubled. Possible to shorten the washing time, rinse water to the discharge liquid Ph value of 4 to 4.5, until the iron content of less than 50mg / L. After large amount of deposits or scale boiler, pickling if more undissolved dead sediment deposited during the cleaning apparatus system, can be washed in water to a Ph value of 4 to 4.5, and then clear the drainage artificially sediment and boiler set box. After washing with this method, you can rinse passivation. 4. Rinse and rust passivating rinse pretreatment passivation i.e., ability to use citrate chelated iron ions, iron ions and residual acid in the system and rinsing the metal surface may occur secondary rust removal. Passivation treatment object is to wash the metal surfaces to form a protective film against corrosion, to prevent corrosion after cleaning, but also for the operation to generate a more solid basis of the magnetic iron oxide protective film good. Top with nitrogen or aqueous acid, and in the case of the pot does not contact the metal-free air may be rinsed with a secondary rust generated after the acidic water rinse, if back, rinsing should be carried out. Must be passivated (except a complete outer passivation cleaning EDTA) the total concentration of iron ions, such as passivated after rinsing, rinsing fluid is not less than 300mg / L after pickling boiler. Exceeds the value, the application of heat deaerator water rinse to replace part of the iron ion concentration is less than this value. The passivation process, the test sample should be regular, such as 1/2 of the initial concentration passivation solution concentration falls, the passivation solution should be supplemented.
