Description

Technical Field

[0001] This utility model belongs to the field of crude benzene-rich oil heating technology, and relates to a crude benzene-rich oil waste heat circulation heating device. Background Technology

[0002] The main drawbacks of existing waste heat crude benzene-rich oil for circulating heating of other materials are low thermal efficiency, high heat loss, environmental pollution, and equipment corrosion. These drawbacks stem from the unstable calorific value, incomplete combustion, and impurities in the waste heat crude benzene-rich oil, preventing efficient and clean heat transfer during the heating process. Furthermore, the combustion of crude benzene-rich oil may produce harmful gases, polluting the environment, and its corrosive substances, such as sulfides, can also corrode the heating equipment.

[0003] Conventional solutions include optimizing combustion processes, improving combustion efficiency, using corrosion-resistant materials, and installing pollution control equipment. However, these methods have drawbacks: optimizing combustion processes and improving combustion efficiency often require additional technical investment and equipment modifications, increasing costs; while using corrosion-resistant materials can extend equipment lifespan, these materials are expensive; and while installing pollution control equipment can reduce environmental pollution, it also requires significant economic investment and generates additional energy consumption and maintenance costs during operation. Therefore, there is an urgent need for a crude benzene-rich oil waste heat recycling heating device to address these issues. Utility Model Content

[0006] The upper end of the heat source conduit is provided with a set of heat-conducting shells for introducing waste heat crude benzene-rich oil, and the lower end of the heat-conducting shells is provided with a set of heating shells for heating external materials. The heating shells and the heat-conducting shells are sealed and fitted together, and a sealing bushing is provided at the connection. The heat-conducting shells are provided with a set of heat injection chambers for introducing waste heat crude benzene-rich oil, and the heating shells are provided with a set of heating chambers for heating external materials with waste heat. The heating chambers and the heat injection chambers are interconnected.

[0007] In a preferred embodiment, a set of material tubes for introducing external materials is provided in the middle of the heating chamber, and a set of outlet tubes for discharging the heated external materials is provided on the left side of the material tubes.

[0008] In a preferred embodiment, a set of feed pipes for introducing external materials to be heated is provided on the right side of the feed pipe. The feed pipe, the outlet pipe, and the feed pipe are sealed and screwed together, and the connection is made by threaded rotation. When the operator wants to use the waste heat of crude benzene-rich oil to heat the external materials, the operator first seals the external crude benzene-rich oil with the waste heat inlet and allows the crude benzene-rich oil to enter the heating chamber inside the heat-conducting shell through the heat source conduit. The crude benzene-rich oil inside the heating chamber is then controlled by an electronic control valve to introduce the crude benzene-rich oil into the heating chamber. Subsequently, the crude benzene-rich oil circulates and heats other materials in the feed pipe inside the heating chamber. The external materials are introduced through the feed pipe, the feed pipe, and the outlet pipe. The crude benzene-rich oil in the heating chamber fully immerses the feed pipe to heat it.

[0012] In a preferred embodiment, a set of lower control valves is provided at the lower right end of the heating chamber for circulating and discharging the waste heat of crude benzene-rich oil inside. The lower control valves are of the same model as the electronic control valves.

[0013] In a preferred embodiment, the lower end of the lower control valve is provided with a set of drain pipes for discharging the waste heat crude benzene-rich oil inside the heating chamber. Outside the drain pipes, there is a set of external circulation pipes for circulating and heating the waste heat crude benzene-rich oil. The lower end of the heating shell is provided with a set of support frames for supporting its lower end. When the operator needs to maintain the circulation of the crude benzene-rich oil, the crude benzene-rich oil inside the heating shell is discharged through the drain pipes by using the lower control valve. The drain pipes can guide the waste heat crude benzene-rich oil inside the heating chamber into the external circulation pipes for circulating and heating the waste heat crude benzene-rich oil, thereby completing the circulation of the crude benzene-rich oil and maintaining the ability of the waste heat crude benzene-rich oil to circulate and heat.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When the staff wants to use the waste heat of crude benzene-rich oil to heat the external materials, the staff first seals the external crude benzene-rich oil with the waste heat inlet, and then lets the crude benzene-rich oil enter the heating chamber inside the heat-conducting shell through the heat source conduit. The crude benzene-rich oil inside the heating chamber is then controlled by an electronic control valve to be introduced into the heating chamber. Subsequently, the crude benzene-rich oil circulates and heats the other materials in the material pipe inside the heating chamber. The external materials are introduced through the feed pipe, material pipe and outlet pipe. The crude benzene-rich oil is fully immersed in the material pipe inside the heating chamber to heat the material pipe.

[0015] By using the lower control valve, the crude benzene-rich oil inside the heating shell is discharged through the drain pipe. The drain pipe can guide the waste heat crude benzene-rich oil inside the heating chamber into the external circulation pipe, which circulates and heats the waste heat crude benzene-rich oil, thereby completing the circulation of the crude benzene-rich oil and maintaining the waste heat crude benzene-rich oil for circulating heating.
