At present, the status of winter heating in rural areas of northern China is as follows: bulk coal heating is dominant, energy utilization rate is low, and a large number of pollutants are discharged; clean heating measures continue to advance, mainly including the promotion of clean coal, energy-saving and efficient furnaces, coal-to-electricity, coal-to-gas, solar energy and other clean energy alternative technologies and centralized insulation pipes. Heating, air pollution control has achieved initial results.
This paper mainly introduces the measure of centralized heat supply with insulating pipes.
With the construction of new countryside, the comprehensive supporting facilities are further improved. In areas where resources and economic conditions permit, centralized heating and insulation pipelines are laid synchronously, and the transformation of centralized heating is realized by utilizing peripheral cogeneration of heat and power, industrial waste heat or heating boilers that meet the requirements. Central heating users are easy to use, safe and reliable, especially in the current situation of rural areas mostly left-behind elderly and children, which is more conducive to ensuring rural living standards. Compared with cities, rural central heating can be managed and operated by village committees or villagers who have been trained by organizations, which reduces the cost of intermediate links and increases farmers'income and employment.
In 2018, Ninghe District of Tianjin City carried out centralized heating renovation of villages and towns under its jurisdiction. Tianjin Honghao Thermal Insulation Pipe Co., Ltd. and Bichen Guozhong Energy Technology (Tianjin) Co., Ltd. signed a strategic annual procurement contract for this project. The overhead steam insulation pipes and polyurethane direct-buried insulation pipes involved in this project are from Honghao Thermal Insulation Pipe of Tianjin City. Supply by Limited Company. Up to now, our company has supplied more than 100 kilometers for it.
In addition, rural building energy-saving awareness is not strong, more attention to the appearance of the building. The randomness of construction results in poor thermal insulation effect, high energy consumption and low comfort. Therefore, in order to improve the quality of life of farmers, we should focus on improving the thermal insulation performance and comfort of residential buildings, integrate building energy conservation into the process of new rural construction, increase the publicity of building energy conservation, increase the effective fund support of the government in the process of housing construction, and formulate and improve legal standards to restrict housing construction to achieve energy conservation and environmental protection. Effect. We should do a good job in technical and policy research to ensure the sustainable development of rural construction.
