Method and apparatus for depositing liquid brine on roadway surface. Substantially horizontally disposed streamer nozzles are employed in conjunction with brine pumps which are operated in correspondence with the forward speed of the treatment vehicle. Substantially horizontally disposed streamer nozzles express the fluid at a rate corresponding with the vehicle forward velocity to effect a relative zero velocity relationship between the pavement and liquid. These streamer nozzles are mounted close to the pavement surface at a location effective to avoid truck induced air turbulence.

The present invention relates to a snow ice maker, comprising a coupling shaft (40) assembly wherein refrigerant injection capillary tubes (20) and a refrigerant gas outlet tube (30) are arranged in a main passage (41), and the passage (41) is closed at a welding part (43) as a result of the capillary tubes (20) and a refrigerant gas inlet tube being simultaneously provided. The refrigerant injection capillary tubes (20) comprise ends (22) arranged in proximity to an injecting position inside a cooling drum, and the refrigerant injection capillary tubes (20) are arranged by collecting the refrigerant injection capillary tubes (20) in the passage (41) of the coupling shaft (40); extending the refrigerant injection capillary tubes (20) to the outside of the cooling drum; combining the refrigerant injection capillary tubes (20) at a multiple connection part (21); and directly connecting the refrigerant injection capillary tubes (20) to a refrigerant supply tube (52) of a refrigerant compressor. The refrigerant gas outlet tube (30) is connected to a multiple inlet tube (33) in an ice-making drum, and the refrigerant gas outlet tube (30) is arranged by directly connecting the refrigerant gas outlet tube (30) through the main passage in the coupling shaft (40), from a connection part (31) outside the cooling drum to a gas inlet tube (54) of a condenser. According to the present invention, clean snow ice can be used because supplied water for ice making is frozen in an ice-making drum, edible powder ice can be obtained by cutting the ice layers of the ice-making drum with a cutter, and water for ice making is sterilized by ultraviolet rays. In addition, the ice-making drum can be cleaned and sterilized by heated water and vapor so that ingredients including milk, sugar and juice can be ice-made and variously used in a summer environment of high temperature and humidity.

A disclosed measuring method for inorganic anions of glacier water is characterized by utilizing a plasma chromatography method and combining a self-made ion exchange chromatographic column to analysis a snow-ice sample solution, so that the chromatographic peak resolution of high-concentration chloride ion and low-concentration nitrites is substantially improved. Compared with the prior art, the measuring method is low in equipment price, short in measuring time, less in usage amount of consumed materials, low in detection cost and high in measuring precision.

The invention provides a shed roof snow melting and deicing system comprising a shed roof, a support frame and a temperature control device. The support frame comprises shed face brackets and a vertical column. The shed roof is fixed to the shed face brackets and comprises a fabric fiber layer, an ultra-hydrophobic nano-coating, a heating layer, a heat conducting layer, a heat insulating layer anda base layer. The heat insulating layer is arranged between the heat conducting layer and the base layer. The heat conducting layer is arranged between the heating layer and the heat insulating layer. The heating layer is arranged between the ultra-hydrophobic nano-coating and the heat conducting layer. The heat conducting layer conducts heat generated by the heating layer. The heating layer is connected with the temperature control device. The temperature control device is fixed to the support frame and controls the heating layer to generate the heat. Through the shed roof snow melting and deicing system, accumulated snow can be molten into water to flow out of the shed roof before forming the thickness of collapse risk, and the situation that the shed roof is collapsed by pressing of the accumulated snow, and consequently personnel and vehicles in a shed are damaged is prevented.
