[0017] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0018] As Figure 1-2 shown, the present utility model provides a technical solution: A reactor for facilitating the heating of low-boiling solvents, including a reactor body 1 and a jacket 2 sleeved on the reactor body 1. The upper part of the jacket 2 is provided with a water outlet 21, and the lower part of the jacket 2 is respectively provided with a drainage port 22 and a water inlet 23. A liquid level gauge 10 is also provided on the jacket 2;
[0019] The water inlet 23 of the jacket 2 is connected to the output end of the hot water generator 3. The hot water generator 3 is a two-in-one-out flange container, and the hot water generator 3 discharges water from the top;
[0020] On both sides of the hot water generator 3, there is a steam inlet and a circulating water inlet. One input end of the hot water generator 3 is connected to the steam delivery pipeline 4, and the steam delivery pipeline 4 includes a steam pipe and a steam control valve. The other input end of the hot water generator 3 is connected to the liquid inlet pipeline 5;
[0021] The steam delivery pipeline 4 is connected to the muffler 31 built inside the hot water generator 3. The muffler 31 is a cylinder connected to the steam delivery pipeline 4, and the cylinder wall of the cylinder is evenly covered with dense holes. When heating steam is introduced into the hot water generator 3 using it, there will be no water hammer phenomenon and excessive noise. A check valve 51 is provided on the liquid inlet pipeline 5;
[0022] Moreover, the liquid inlet pipeline 5 is respectively connected to the cold water pipeline 6 and the return water pipeline 7. The cold water pipeline 6 includes a water pipe and a cold water control valve. The hot steam in the steam delivery pipeline 4 and the low-temperature water in the return water pipeline 7 converge and exchange heat inside the hot water generator 3;
[0023] The return water pipeline 7 is connected to the water outlet 21 of the jacket 2. A pipeline pump 8 is provided on the return water pipeline 7, and a circulation valve 11 is provided on the return water pipeline 7. The circulation valve 11 is connected to the outlet end of the pipeline pump 8. The main channel of the circulation valve 11 is connected to the return water pipeline 7, and the bypass return port of the circulation valve 11 is connected to the drain port 22. A drain valve 221 is provided at the bottom of the drain port 22. The circulation valve 11 is a mechanical valve. When the pipeline pump 8 is operating normally, the main channel is in normal circulation. When the pipeline pump 8 is operating below load, the bypass return port 111 automatically opens and is connected to the drain port 22 for reflux to ensure the normal operation of the pipeline pump 8. The top of the return water pipeline 7 is connected to the water outlet pipe 9, and is connected to the factory circulating water system through the water outlet pipe 9.
[0024] When hot water is required to heat the materials in the reactor body 1, the following steps can be carried out:
[0025] Open the cold water control valve of the cold water pipeline 6 to fill the jacket 2 with water, and the liquid level gauge 10 can monitor the water level.
[0026] Close the cold water control valve, turn on the pipeline pump 8, and adjust the steam control valve of the steam delivery pipeline 4. The pipeline pump 8 circulates water through the return water pipeline 7, and hot water will be generated inside the hot water generator 3. The hot water enters the jacket 2, and heat convection will be generated. The hot water rises inside the jacket 2, and at the same time, the materials in the reactor body 1 are heated;
[0027] The cold water in the jacket 2 can be squeezed out and discharged through the water outlet pipe 9. Most of it completes the cycle of reheating and circulation through the return water pipeline 7, the pipeline pump 8, the circulation valve 11, the liquid inlet pipeline 5, the check valve 51, and the hot water generator 3. A small part of the incremental water generated due to steam condensation enters the factory circulating water system through the water outlet pipe 9.
[0028] If it is necessary to cool the materials in the reactor body 1, the steam control valve of the steam delivery pipeline 4 and the pipeline pump 8 can be closed, and the cold water control valve of the cold water pipeline 6 can be opened. Cold water enters from the bottom of the jacket 2 and enters the factory circulating water system through the water outlet pipe 9 from the upper part, completing the cooling of the materials.
