Abstract

The invention relates to a snow melting system and a method for recycling accumulated snow, particularly to a hot-air circulating two-layered snow melting system and the method for recycling accumulated snow, which solve the problems that the existing method for treating the accumulated snow wastes resource and pollutes the environment. The hot-air circulating two-layered snow melting system includes a two-layered subsurface-flow constructed wetland landscape pond and a snow melting well, wherein the snow melting well includes a thermal insulation cover, a well wall, a thermal insulation operation door, a heating grate A, a heating layer, a bottom heating pipe, a water drain pipe, a first step, a first rotating shaft, a heating vertical pipe, a groove and a filter grating. The method includes the following steps: collecting the accumulated snow, throwing the accumulated snow into the snow melting well through the thermal insulation operation door, and carrying the melted snow to the two-layered subsurface-flow pond through the deposited and overflowed clear water. The hot-air circulating two-layered snow melting system avoids the environmental pollution caused by snow melting agent, as well as the resource waste caused during accumulated snow transferring and toppling, is environment-friendly, facilitates the timely accumulated snow treatment, avoids the pollution caused by long-time exposure, and solves the road freezing problem caused by repeated freeze-thaw. The method is used for recycling the accumulated snow.

Description

technical field [0001] The invention relates to a snow melting system and a method for recycling and utilizing snow accumulation. Background technique [0002] The problem of snow removal on roads and parks in northern cities in winter in my country not only affects the normal life of urban traffic and residents, but also relates to environmental maintenance and effective use of water resources. It is an issue with multiple benefits. Cities in the cold regions of northern my country have long winters and harsh climates, making rainwater recovery and treatment facilities unable to maintain continuous operation, and it is difficult to maintain and promote them due to seasonal idleness. There are not many studies on the utilization of ice and snow resources in our country, and most of them stay on theoretical analysis. Many foreign cities have actively paid attention to the treatment of winter snowfall in cold cities. In addition to research and development of advanced snow rem...
