[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] In the prior art, during the production of water-based high molecular polymers, the process exhaust gas generated contains a trace amount of acrylic acid ester monomers. However, acrylic acid ester monomers are easily polymerized, so after the reactor exhaust gas condenser has been used for a period of time, acrylic acid ester polymers will appear in the condenser tube of the condenser, seriously blocking the condenser tube and affecting the condensation effect of the condenser. The following describes a condenser spray cooling device provided by some embodiments of the present invention in conjunction with the accompanying drawings.

[0023] Example 1:

[0024] In order to reduce the blockage of polymer in the condenser tube, Figure 1 and Figure 2 as well as Figure 3 As shown, a spray cooling device in a condenser is proposed. A reaction mechanism 1 is set as the main body of the device, and water-based acrylic ester polymers are produced and processed through the reaction mechanism 1. A cooling mechanism 2 is set on the condenser body 104, and the cooling mechanism 2 is used to reduce the polymer in the condenser tube. A collecting mechanism 3 is set on the cooling mechanism 2, and the collecting mechanism 3 is used to collect and recycle the atomized water droplets.

[0025] In order to ensure the condensation effect of the condenser body 104, a cooling mechanism 2 is proposed. A fixing ring 201 is installed on the outside of the condenser body 104. A connecting pipe a202 is fixedly installed on the fixing ring 201. A flow meter 203 is installed on the connecting pipe a202. A pneumatic valve 204 is installed on the connecting pipe a202. The bottom of the connecting pipe a202 is fixedly connected to a connecting pipe 205. A mist water spray head 206 is installed at one end of the connecting pipe 205. The position of the connecting pipe a202 is fixed by the fixing ring 201. The connecting pipe a202 is connected to the mist water spray head 206 through the connecting pipe 205. The two spray heads 206 are connected, and at the same time, the connecting pipe a202 is a DN15 stainless steel pure water pipe with good corrosion resistance and wear resistance, thereby improving the service life of the connecting pipe a202. By opening the pneumatic valve 204 and adjusting the flow meter 203, mist pure water is sprayed to the lower head of the condenser body 104 through the mist water spray head 206, thereby cooling the exhaust gas in the condenser tube, so that the liquid after the exhaust gas is cooled flows into the reactor 101, thereby reducing the polymer blockage in the condenser tube, extending the cleaning cycle of the blocked polymer, and reducing the cleaning workload of the staff.

[0026] To process and produce waterborne polymers, a reaction mechanism 1 is proposed. It comprises a reactor 101, a condenser 104 mounted on the reactor 101, and a dropping funnel 102 mounted on the top of the reactor 101. A return elbow 103 is fixedly connected to the top of the reactor 101, one end of which communicates with the condenser 104. Liquid is slowly and evenly added to the reactor 101 via the dropping funnel 102. The condenser 104 cools and condenses the high-temperature, high-pressure gas generated within the reactor 101, thereby condensing the steam generated within the reactor 101 into liquid for collection and reuse.

[0027] Example 2:

[0028] On the basis of Example 1, the technical solution proposed in Example 1 is used to solve the problem in the prior art that after the condenser has been used for a period of time, acrylic polymers will appear in the condenser tube of the condenser, seriously blocking the condenser tube, affecting the condensation effect of the condenser, and requiring regular manual cleaning of the polymer, wasting manpower and material resources. However, when mist pure water is sprayed on the lower head of the condenser body 104, a large amount of atomized water droplets will also accumulate on the surface of the condenser tube and the connecting pipe a202 near the mist water spray head 206. If they are not collected, it will cause a waste of water resources.

[0029] In order to recycle the atomized water droplets sprayed by the mist water spray head 206, Figure 1 and Figure 2 as well as Figure 4 As shown, a collecting mechanism 3 is proposed, which is achieved by installing a collecting bucket 301 at the condenser pipe, a circular hole 302 is opened on one side of the collecting bucket 301, and a branch pipe 303 is fixedly connected to the other side of the collecting bucket 301, and one end of the branch pipe 303 is fixedly connected to a connecting pipe b304, and a micro-adjusting water pump 305 is installed in the connecting pipe b304, and the top of the connecting pipe b304 is connected to one end of the connecting pipe a202. The diameter of the circular hole 302 is the same as the outer diameter of the return elbow 103, and the collecting bucket 301 is located below the mist water sprinkler head 206. The micro-adjusting water pump 305 allows the liquid droplets in the collecting bucket 301 to enter the connecting pipe b304 from the branch pipe 303, and then enter the connecting pipe a202 from the connecting pipe b304, so that the lower head of the condenser body 104 is continuously sprayed by the mist water sprinkler head 206, thereby completing the recycling of the atomized water droplets, protecting the environment, and avoiding the waste of water resources.
