The identification of Fangkuai automatic dzl sawdust fire boiler plant softened water pollution type should integrate raw water quality, design parameters, pollution index and operation record. Equipment performance changes and microbial indicators to judge: (1) Colloidal contamination: colloid contamination, usually accompanied by the following two characteristics: a, in the pretreatment of the micro-filter clogging very fast, especially the pressure difference increased very fast, B, The SDI value is usually above 2.5. (2) microbial contamination: when microbial contamination occurs, the total number of bacteria in both water and concentrated water of RO equipment is relatively high, and must not be maintained and sterilized according to the requirements in peacetime. 3 pot Calcareous scale: can be judged by raw water quality and design parameters. For carbonate water, if the recovery rate is 75%, the LSI of the concentrated liquid should be less than 1 if the recovery rate is 75%, and the LSI of the concentrated liquid should be less than zero when the scale inhibitor is not added, and the calcium scale will not be produced generally. 4 the performance changes of different parts of the test assembly can be judged by the 1-inch 4-inch PVC plastic tube inserted into the assembly. (5) judging the type of pollution according to the change of equipment performance. (6) pickling (such as citric acid, dilute HNO3) can be used to judge calcium scale according to the cleaning effect and cleaning fluid, and through the analysis of the composition of the cleaning fluid, the evidence of one-step progress can be obtained. Real. Chemical analysis of cleaning fluid: taking raw water, cleaning liquid, cleaning fluid, three sample analysis.
Battle to win the blue sky, is the major decisions and plans to make a big party in the nineteenth, and is for building a moderately prosperous society, to improve the quality of life of citizens and establish a beautiful China's development goals. To fully implement the nineteen spirit, promote the governance of air pollution intensity and improve the living quality of the environment, this year March 8, Zhengzhou Municipal Party Committee General Office, Zhengzhou Municipal People's Government Office issued the 2018 air pollution control program and the corresponding subsidy policy, the implementation of low-nitrogen gas automatic dzl sawdust fire boiler retrofit demonstration project, as follows:
Before the end of September 2018, the city's more than 20 tons of steam (with), and the urban areas more than 4 tons of steam (with) the completion of gas-fired low-nitrogen transformation project demonstration projects, nitrogen oxides emission concentration is not higher than 30 mg / cubic meter, City level financial awards complement carried out in accordance with the 40% investment in equipment;
Before the end of September 2018, the city's more than 4 tons of steam (with), and the urban areas more than 2 tons of steam (including) low nitrogen gas boiler reconstruction project completed demonstration projects, nitrogen oxides emission concentration is not higher than 30 mg / cubic meter, City level financial awards complement carried out according to 30% of equipment investment;
Before the end of April 2019, the city completed all gas-fired low-nitrogen transformation, nitrogen oxides emission concentration is not higher than 30 mg / cubic meter, the municipal finances awards complement of 15% investment in equipment.
Especially cost-effective, direct impact to buy gas automatic dzl sawdust fire boiler, according to the focus on form and market point of view, the choice of gas boiler is not an easy thing. Through the relevant price, combined with the associated design and analysis to understand the form, directly determine the quality of the gas boiler is the key, we can see now each one has a gas boiler are gradually expanding market potential.
Condensing technology as advanced new technology, but also to ensure the continued stability and durability of the device. Although condensing boilers cost is very high, but the boiler is not a small purchase costs, the boiler can only guarantee stable for 20 years or even longer time, is excellent value for money.
