Description

Technical Field

[0001] This invention relates to the field of emergency response technology for road icing in extreme weather, and particularly to a modular multi-point jet-type thermal de-icing device and a complete set of de-icing equipment. Background Technology

[0002] Current road de-icing technologies mainly rely on mechanical de-icing (breaking, shoveling, sweeping) and the application of de-icing agents (salt). Purely mechanical methods are difficult to remove thin ice and easily damage the road surface. Applying de-icing agents (salt) can easily cause corrosion to road appurtenances and bridges, and cause irreversible damage to surrounding green vegetation. Currently, there is a lack of effective methods for dealing with ice thinner than 10mm. Aero-engine turbofan hot snow blowers are common thermal snow melting equipment on the market, mainly used in airports. They use aircraft engines as power, operate at speeds of 5-20km / h, have a maximum blowing speed of approximately 32m / s, and can reach a maximum hot air temperature of 750℃, quickly melting snow and drying icy roads. However, this method is technically complex, difficult to design and manufacture, and has high maintenance and operating costs. It is not well-suited for highway and municipal road conditions, and the heating power is difficult to control precisely, easily causing heat overflow that can scorch and kill surrounding green vegetation.

[0003] Based on the above-mentioned deficiencies, it is no longer able to meet the requirements of safety, smooth traffic, and high-quality maintenance of modern highways (especially expressways and municipal roads), and there is an urgent need to develop new technologies, processes, and equipment for the efficient treatment of light icing on road surfaces.

Detailed Implementation

[0020] The following detailed description of a specific embodiment of the present invention is provided in conjunction with the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0021] Example 1 like Figures 1 to 5 As shown, in order to solve the problems of existing mechanical de-icing (breaking, shoveling, sweeping) and the application of de-icing agents (salt) which easily cause road damage and de-icing agents (salt) that easily cause corrosion of road appurtenances and bridges, this application provides a modular multi-point jet thermal de-icing device, including a heat generation unit and a high-pressure jetting unit. The heat generation unit is used to provide heat to melt the ice layer. The high-pressure jetting unit pressurizes the outside air and inputs it into the heat generation unit, and outputs the heated air to the ground. In order to overcome the problem that the hot air blown by the aviation turbofan hot snow blower on the market covers multiple lanes and the heat overflow easily causes the surrounding green vegetation to be scorched and killed, this embodiment also includes a heat overflow protection device 8. The heat overflow protection device has multiple protective components, which are distributed outside the high-pressure jetting unit. The number can be two or four. When there are two, they can be arranged on the left and right sides respectively. This embodiment takes two protective components as an example. Specifically, the heat generation unit includes a combustion chamber 2, a burner 1, a high-pressure chamber 3, and a hot air chamber 4; the high-pressure injection unit includes a high-pressure fan 5, a lower air hood 6, and a high-pressure nozzle 7. The burner 1 is located at the front end of the combustion chamber 2 and is fixed on the front facade of the high-pressure chamber 3. The high-pressure chamber 3 encloses the combustion chamber 2. The high-pressure blower 5 is fixedly installed outside the high-pressure chamber 3 and its output end is connected to the high-pressure chamber 3. It can input outside air into the high-pressure chamber 3 and increase the internal pressure of the high-pressure chamber 3. The number of high-pressure blowers 5 is at least one. In this embodiment, two are used as an example and are symmetrically arranged on the left and right sides of the burner 1. The tail end of the high-pressure chamber 3 is connected to the hot air chamber 4. The bottom of the hot air chamber 4 is provided with an air outlet. There can be one or more air outlets. All air outlets are connected to the lower air outlets on the upper surface of the lower air cover 6. Several sets of high-pressure nozzles 7 are fixed to the lower air cover 6 with flanges and connected to several sets of lower air outlets. In this embodiment, under the action of the heat generation unit and the high-pressure injection unit, a high-temperature and high-pressure airflow is generated, and the airflow is blown obliquely near the ground through the high-pressure nozzle to lightly condense the ice layer, which can effectively lift the ice layer and blow it to both sides of the road, effectively reducing heat energy consumption.

[0022] Several sets of high-pressure nozzles 7 can be distributed along a direction perpendicular to the forward direction, and are evenly arranged in a left-right mirror image, with the nozzles' outlet air direction evenly distributed to the left and right. In this embodiment, the high-pressure nozzle 7 is welded together from a flange plate 7-1, a hot air hood 7-2, and several sets of guide plates 7-3. The lower air outlet on the upper surface of the lower air hood 6 is located inside the flange plate 7-1. Several sets of guide plates 7-3 divide the internal space of the high-pressure nozzle 7 into multiple independent spaces. The high-pressure nozzle is equipped with several sets of side exhaust ports 7-4 and bottom exhaust ports 7-5. After the high-temperature and high-pressure gas enters the independent space, it is discharged to the ground through these exhaust ports, melting the ground ice layer and blowing the ice layer to both sides. Here, blowing the ice layer refers to the ice layer of general or relatively thin thickness, not specifically to the very thick icy road surface environment in high-latitude regions. In this embodiment, the side exhaust port 7-4 of the high-pressure nozzle 7 has an angle A of 5°-15° with the horizontal ground, and the ground clearance H of the high-pressure nozzle 7 is 50-100mm. The heat overflow protection device 8 can be designed as a telescopic structure. Specifically, the body of the protection component is a plate-shaped structure, which can be in a vertical or inclined state. The spacing can be adjusted by a linear telescopic structure fixed on the vehicle body of the modular multi-point jet thermal ice melting device or directly fixed on the outer wall of the lower hood 6. The linear telescopic structure can be a hydraulic cylinder or a pneumatic cylinder. It not only protects the surrounding green vegetation from being scorched by heat, but also realizes the adjustment of the thermal ice melting width. In this embodiment, the stepless adjustment of 3000-4500mm is taken as an example. In addition, the location of the heat overflow protection device can correspond to the installation location of the high-pressure blower. In this way, the high-pressure blower can input the air (higher than the ambient temperature) that moves upward along the heat overflow protection device into the high-pressure chamber, which can utilize heat and save energy. The technical solution proposed in this embodiment can achieve de-icing function for ground that has just frozen or has a low ice thickness. For road surfaces that have been frozen for a long time and have a high ice thickness, it can also play a certain role in cleaning or pre-treatment. Subsequently, it can be matched with other mechanical de-icing equipment to carry out thorough ice removal operations.
