Abstract
Description
Technical Field
[0001] This utility model belongs to the field of chemical production technology, specifically relating to a device for factory heating using a converter. Background Technology
[0002] In the process of producing vinyl chloride using the calcium carbide method, acetylene and hydrogen chloride undergo an addition reaction under the action of a catalyst to produce vinyl chloride. This chemical reaction is exothermic, meaning that heat is released during the reaction, requiring a converter in conjunction with a hot water circulation system to absorb the heat.
[0003] Currently, factories typically use a hot water circulation system with a converter to remove heat from the vinyl chloride conversion reaction, requiring the hot water tank temperature to be controlled at 85±2℃. During prolonged operation, a significant amount of heat generated by the system is transferred to the hot water tank via the hot water circulation, causing the tank temperature to exceed the standard value. This severely impacts production, necessitating a halt to vinyl chloride production and prolonged cooling of the converter. This not only disrupts normal production but also results in substantial waste of preheating resources. Furthermore, the exothermic reaction in the converter causes the system temperature to rise. If this heat is not effectively removed, it can lead to uncontrolled reaction, affecting product quality and catalyst stability, and even damaging equipment. Simultaneously, the large amount of heat carried by the hot water is transferred to the cooling water system, increasing the production load and creating a vicious cycle that wastes resources and increases the production cost of vinyl chloride. Utility Model Content
[0004] This invention provides a device for heating a factory using a converter, in order to solve the problem that in the current vinyl chloride production process, it is necessary to cool down the converter, which affects production efficiency and increases production costs.
[0005] The technical solution of this utility model is: a device for factory heating using a converter, including a converter and a hot water tank, with an inlet pipe and a return pipe between the converter and the hot water tank, a hot water pump installed on the inlet pipe, and a heat exchanger. The hot water outlet of the heat exchanger is connected to the return pipe through a heat exchange return pipe, the hot water inlet of the heat exchanger is connected to the inlet pipe through a heat exchange inlet pipe, the heat exchange inlet pipe is connected to the hot water pump, the heat exchange outlet of the heat exchanger is connected to the inlet of the heating equipment through a heating inlet pipe, the outlet of the heating equipment is connected to the water storage tank through a heating drain pipe, the water storage tank is connected to the heat exchange inlet of the heat exchanger through a heating return pipe, and a heating pump is installed on the heating return pipe.
[0006] As a further improvement of this utility model, a water supply pipe is also installed on the water storage tank.
[0007] The beneficial effects of this invention are as follows: This invention transfers the heat from the converter to the factory's heating equipment via a heat exchanger, allowing the hot water circulation system to operate at the standard temperature without needing to stop production to cool the converter, and also avoiding significant waste of the converter's heat, thus reducing production costs. This invention has a simple structure, stable operation, and effectively solves the problem of needing to cool the converter during production, which affects production efficiency and reduces production costs, making it highly valuable for widespread application.

Detailed Implementation
[0010] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0011] like Figure 1 As shown, a device for factory heating using a converter includes a converter 4 and a hot water tank 1. A water inlet pipe 3 and a water return pipe 5 are provided between the converter 4 and the hot water tank 1. A hot water pump 2 is provided on the water inlet pipe 3.
[0012] A device for factory heating using a converter further includes a heat exchanger 7. The hot water outlet of the heat exchanger 7 is connected to the return water pipe 5 via a heat exchange return water pipe 8. The hot water inlet of the heat exchanger 7 is connected to the water supply pipe 3 via a heat exchange supply water pipe 6. The heat exchange supply water pipe 6 is connected to the hot water pump 2. The heat exchange outlet of the heat exchanger 7 is connected to the inlet of the heating equipment 9 via a heating supply water pipe 15. The outlet of the heating equipment 9 is connected to the water storage tank 11 via a heating drain pipe 12. The water storage tank 11 is connected to the heat exchange inlet of the heat exchanger 7 via a heating return water pipe 14. A heating pump 10 is installed on the heating return water pipe 14.
[0013] A water supply pipe 13 is also installed on the water storage tank 11.
[0014] During use, the internal heat generated by the converter 4 heats the water, which is then transported to the hot water tank 1 via the return water pipe 5. The hot water pump 2 transports the cooled hot water from the hot water tank 1 to the converter 4 via the inlet water pipe 3 to continue heat exchange, forming a hot water circulation system. The hot water pump 2 also delivers hot water to the heat exchanger 7 via the heat exchange inlet water pipe 6. After heat exchange, the hot water is transported back to the hot water tank 1 via the heat exchange return water pipe 8. The water after heat exchange effectively lowers the temperature of the hot water tank 1, ensuring that the hot water circulation system can be used for a long time. After heat exchange, the heat exchanger 7 transports the heating water to the heating equipment 9 via the heating inlet water pipe 15. The used hot water is transported to the storage tank 11 via the heating drain pipe 12, and finally transported to the heat exchanger 7 via the heating pump 10 to form a heating circulation system. The circulation can be replenished via the water supply pipe 13.
