All other embodiments, which can be made by those skilled in the art based on the embodiments of the present utility model without making any inventive effort, shall fall within the scope of the present utility model.
Example 1
As shown in fig. 1, the embodiment provides a steam generator utilizing asphalt waste heat, which comprises a large sealing head 1 and a small sealing head 2, wherein a plurality of asphalt pipes 3 are connected between the large sealing head 1 and the small sealing head 2, and a shell 4 is arranged outside the asphalt pipes 3. The connection mode of the large seal head 1, the small seal head 2 and the asphalt pipe 3 can adopt the existing floating head heat exchanger, and the specific structure thereof is not repeated here. The large seal head 1 is provided with an asphalt inlet 101 and an asphalt outlet 102, wherein the asphalt inlet 101 is positioned at the top of the large seal head 1, and the asphalt outlet 102 is positioned at the bottom; the produced high-temperature asphalt enters the asphalt pipe 3 through the asphalt inlet 101, and is discharged from the asphalt outlet 102 after heat exchange. In order to fully utilize the heat of asphalt, the small seal head 2 can be arranged in the shell 4, so that the asphalt in the small seal head 2 can also participate in heat exchange. Meanwhile, a drain 404 is provided at the bottom of the housing 4 for discharging scale and the like in the housing 4.
The shell 4 is provided with a water inlet 401 and a water outlet 402, the water inlet 401 is positioned at the top of the shell 4 and is connected with the water tank through a water inlet pipe, and water is introduced into the shell 4 through the water inlet 401 for heat exchange with the high-temperature asphalt in the asphalt pipe 3. A water outlet 402 is located at the bottom of the housing 4 for draining water from the steam generator when it is inactive. The steam generator of the embodiment fully utilizes the heat exchange between the asphalt waste heat and water to generate steam, and the steam can be used for production and also achieves the aim of cooling asphalt. In addition, the top of the housing 4 can be designed to have a large gap with the asphalt pipe 3 for temporarily storing the generated water vapor.
The top of the shell 4 is connected with a steam drum 6 through a steam rising pipe 5, and the steam drum 6 is connected with a water tank through a condensate falling pipe. The steam generated in the shell 4 enters the steam drum 6 through the steam rising pipe 5, after gas-liquid separation, the steam can enter the steam pipe network for use through the steam outlet of the steam drum 6, and the separated condensate is returned to the water tank for recycling. The steam generator of the embodiment not only realizes the utilization of the residual heat of the asphalt, but also achieves the aim of cooling the asphalt, and saves the energy for cooling the asphalt by using the condenser; meanwhile, the water vapor can be produced for production and use, thereby achieving two purposes.
In addition, in order to enable the water and the asphalt to fully generate heat exchange, the heat dissipation fins 7 can be arranged on the asphalt pipe 3, so that the heat of the high-temperature asphalt in the asphalt pipe 3 can be dispersed on the heat dissipation fins 7, and when the water contacts the heat dissipation fins 7, the heat can be quickly taken away, thereby improving the heat exchange efficiency and realizing the quick cooling of the asphalt.
Along with the continuous generation of vapor in the shell 4, the internal water volume gradually decreases, so that in order to enable all the asphalt pipes 3 to be immersed into water for heat exchange, the heat exchange efficiency is ensured, a liquid level meter 8 can be arranged in the shell 4, a valve is arranged on a water inlet pipe, and the liquid level meter 8 and the valve are electrically connected with a controller. The liquid level of water in the shell 4 is monitored in real time through the liquid level meter 8, and when the liquid level meter detects that the water amount in the shell 4 is lower than a preset value, water can be timely supplemented into the shell 4 through the valve on the water inlet pipe, so that the water level is kept at a proper height.
Example 2
