The following three aspects of the supporting equipment facilities in the production and use of the superconductor asphalt thermal equipment and the heat-conducting oil asphalt heating equipment, the early investment, the production operation and the maintenance cost and the like are compared in detail. The heat conducting oil asphalt heating technology has large market occupation. However, the disadvantages of this type of device are also evident, for example, (1) the heating times are too long, such as: the natural temperature (20-30 ℃) is increased to 100 ℃ and needs 48 hours or even longer time; (2) the heat value utilization rate is low. The heat conducting oil circulates in the pipeline after being heated, and the scaling phenomenon of the hot oil on the inner wall of the pipeline is more serious along with the prolonging of the service time, so that the heat conduction of the heat conducting oil is directly influenced. The use and maintenance costs are high. In the circulation process of the heat conduction oil, the heat conduction of the heat conduction oil is influenced by the scaling inside the circulation pipeline, and the heat utilization rate can only be maintained between 34 and 45 percent; (3) the pipeline needs to be cleaned regularly, cleaning fluid and labor cost need about 3000-5000 yuan, after new heat conduction oil is added and supplemented, the heat conduction oil needs to be dehydrated by system circulation, the time is 48 hours in short time, even the time is longer, the heat conduction oil boiler works continuously for 48 hours, and the gas cost expenditure is as follows: the gas consumption of 100 ten thousand kilocalories of gas-fired boilers per hour is 117.6 cubic meters per hour, and the gas consumption per cubic meter is calculated according to 2.8 yuan per cubic meter: the consumption of natural gas in 48 hours is 117.6 cubic meters/hour multiplied by 48 hours which is 5644.8 cubic meters, the gas cost is 5644.8 cubic meters multiplied by 2.8 yuan/cubic meter which is 15805.4 yuan, and the use cost is increased; (4) the capital investment of facilities is large due to the early-stage matched equipment. The method comprises the steps of a heat conduction oil boiler, a hot oil circulating pipeline, manufacturing and installation, a hot oil circulating pump, heat conduction oil, a natural gas pressure reducing station, manufacturing and installation of pipelines and the like. The supporting equipment facilities are in place, and the heat conducting oil heating equipment is in normal production and operation. (5) The production cost of asphalt heating is increased, and the production cost of the asphalt material is also increased. The natural gas can generate toxic and harmful gases such as carbon dioxide and the like during combustion, and the asphalt heating cost is increased by purchasing the emission indexes of the toxic and harmful gases every year. (see attached Table 1 for details)

The superconducting asphalt thermal equipment is used for heating asphalt, and the following achievements can be obtained (the data are shown in the attached table 2 in detail):

(1) simple corollary equipment and facilities. The super-conductor asphalt thermal equipment adopts a super-conductor heat pipe asphalt heating technology and is independent asphalt heating equipment. The oil unloading and conveying machine carried by the machine in production can complete the oil unloading and conveying functions. Only one item of matched equipment and facilities saves investment by more than 30 ten thousand yuan compared with heat-conducting oil asphalt heating equipment.

The superconductor asphalt thermal equipment can be produced by 1 machine or by connecting a plurality of machines in parallel. The oil unloading and conveying mechanism is simple in structure, can move and walk, and is convenient to use. The operation cost of pipeline maintenance and the like is saved.

(2) The heating cost of the asphalt is reduced by 30-50%; the heating time is shortened and can be customized. The heat conducting oil asphalt heating equipment generally uses natural gas as a heat source to heat asphalt. The heat conducting oil is in a pipeline arranged in the asphalt tank, and the purpose of heating the asphalt is achieved through forced circulation of a hot oil pump. Taking heating 200 tons of asphalt as an example (100-130 ℃), 10 hours or even longer time is generally needed, and the cost of consumed fuel gas is as follows; the gas consumption per hour of a 100 ten thousand kilocalories gas boiler is 117.6 cubic meters per hour. The price of natural gas is calculated as 2.8 yuan/cubic meter: 117.6 cubic meters/hour × 10 hours × 2.8 yuan/cubic meter 3292.8 yuan; 3292.8 yuan/200 ton/16.5 yuan/ton, and the cost of manpower, electricity, maintenance and the like is not included here. The heating cost of the asphalt from 100 ℃ to 130 ℃ is 16.5 yuan/ton per ton.

The heating power of the complete machine of the superconductor asphalt thermal equipment is 132 kilowatts/hour, the temperature of 30 tons of asphalt is raised from 100 ℃ to 130 ℃, and the electric energy is 576 kilowatts/hour in the process of temperature rise. Calculating according to the step electricity price and the peak electricity price of 1.03 yuan kilowatt/hour: 576 kw/hr × 1.03 kw/hr 593.28 yuan, 593.28 yuan/30 ton 19.8 yuan/ton, and the heating cost per ton of asphalt is 19.8 yuan. This is the net heating cost. If the power is leveled to 0.73 yuan kilowatt/hour, the calculation is as follows: 576 kilowatts/hour x 0.73 kilowatts/hour is 420.5 yuan. 420.5 yuan/30 ton is 14 yuan/ton, valley current is 0.43 yuan kilowatt/hour, and calculation is carried out: 576 kilowatt/hour x 0.43 yuan kilowatt/hour is 247.7 yuan, 247.7 yuan/30 ton is 8.2 yuan/ton, and the heating cost of each ton of asphalt is 8.2 yuan, so that the heating cost of the asphalt is lower. After the temperature rise of the asphalt is finished, the special external heat preservation design of the superconductor asphalt thermal equipment enables partial heat stored in the bottom space of the equipment to be preserved for 10 hours without losing the temperature.

After the asphalt reaches the set temperature, the heat conduction oil of the asphalt heating equipment still continues to circularly work to prevent the temperature of the asphalt from decreasing, and the cost is as follows: the heat value of natural gas is generally 8500 kilocalories per cubic meter, the heat conducting oil boiler is 100 kilocalories, and the calculation formula is as follows: 100 kilocalories per hour/8500 kilocalories per cubic meter 117.6 cubic meters per hour. 2.8 yuan per cubic meter of natural gas: 117.6 m/hr 2.8 yuan/m 329.3 yuan, 329.3 yuan per hour for system operation.

The successful research and development of the superconductor asphalt thermal equipment is a revolution of the existing heat transfer oil heating technology. The asphalt heating technology instead of heat-conducting oil is bound to be moved into the industries of construction engineering, traffic engineering, road transportation, petroleum exploitation, petrochemical industry and the like, and great social and economic benefits are brought into play.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
