Description

Technical Field

[0001] This utility model relates to the field of solid-state degassing technology, and in particular to a solid-state cooling degassing system. Background Technology

[0002] Dimethyl carbonate (DMC), also known as di(trichloromethyl) carbonate, is widely used in industries such as pesticides, pharmaceuticals, fragrances, and dyes. It is synthesized directly from dimethyl carbonate (DMC) and chlorine. The product is in liquid form and is packaged as the final product after cooling and solidification.

[0003] In the existing production process, a small amount of chlorine and hydrogen chloride dissolve in the product during solidification. During the cooling and slagging process, a large amount of acidic gas is generated, which is extremely corrosive. The existing automatic slagging machine cannot solve the corrosion problem of the equipment's metal parts. At the same time, the existing automatic slagging machine has low automation processing capability, which affects the lifespan of the slagging machine and the factory's production capacity. Utility Model Content

By setting a conveyor belt in the cooling chamber, it can perform automated sheet-forming and packaging operations. At the same time, an external gas scrubbing tower can process the gas, filter out acidic gases, and recover solid-state particles and chlorine. This solves the problems of existing automatic sheet-forming machines having low automation levels and being unable to handle the gases generated during the sheet-forming process, which leads to low equipment lifespan, processing efficiency, and low resource reuse rate.

[0009] Furthermore, a discharge pump is also provided at the bottom of the gas scrubbing tower, and the discharge pump is connected to a reactor. The discharge pump is used to pump the dissolved liquid in the gas scrubbing tower into the reactor.

[0010] Furthermore, a gas phase condenser is connected to the top of the gas scrubbing tower, and a reflux tank is connected to the output end of the gas phase condenser. The bottom of the reflux tank is connected to the gas scrubbing tower.

[0011] Furthermore, the spray tank is connected to a solid light input port via a second conveying pipeline.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figure 1 , Figure 1 This is a schematic diagram illustrating the principle and structure of the present invention. The present invention provides a solidification cooling and degassing system, including a spray tank 1 and a cooling chamber 2. The bottom of the spray tank 1 is connected to the cooling chamber 2 via a first conveying pipeline 101. One end of the first conveying pipeline 101 extending into the spray tank 1 is connected to a nozzle 1011. The first conveying pipeline 101 is used to convey the liquid solidification agent in the spray tank 1 to the cooling chamber 2 via the nozzle 1011. The spray tank 1 is connected to a solidification input port 1021 via a second conveying pipeline 102. Both line 101 and the second delivery pipeline 102 include a jacket layer, and heat-conducting oil is provided in the jacket layer. The heat-conducting oil is used to keep the temperature of the first delivery pipeline 101 and the second delivery pipeline 102 not lower than a first temperature, which is set to 85°C. The outside of the nozzle 1011 is wrapped with heat-conducting putty, which is used to ensure that the temperature at the nozzle 1011 is not less than 85°C. The first delivery pipeline 101 is not equipped with a valve. After the solidification spraying is completed, the hot nitrogen flow rate is adjusted to keep the pipe unobstructed and the temperature of the nozzle 1011 up to standard.

[0022] The spray tank 1 is also connected to a nitrogen heater 103, which is used to input heated nitrogen into the spray tank 1. The temperature of the input nitrogen is not lower than 85°C, which is used to maintain the temperature inside the spray tank 1. The spray tank 1 is equipped with an outer jacket, and heat transfer oil is installed inside the outer jacket for heat preservation.

[0023] A flow guide hood 202 is installed inside the cooling chamber 2, and a cooling fan 203 is connected to the outside of the cooling chamber 2. The cooling fan 203 is used to transport cold air into the flow guide hood 202, and the nozzle 1011 passes through the top of the flow guide hood 202. The first conveying pipeline 101 sprays the material out through the nozzle 1011 inside the flow guide hood 202. After the small droplets are sprayed out, they come into contact with the cold air transported by the cooling fan 203 and are rapidly cooled, and the acidic gas dissolved in the material is quickly discharged. A conveyor belt 201 is installed at the bottom of the cooling chamber 2. The cooling chamber 2 is used to cool the liquid solid material to form solid granular material, and the conveyor belt 201 is used to output the solid granular material to the outside of the cooling chamber 2. The cooling chamber 2 is a sealed space with a sufficiently large space, which forces the sprayed granular material to settle to the bottom of the conveyor belt 201. The acidic gas is transported to the gas scrubbing tower 3, and the solid particles on the conveyor belt 201 enter the automatic packaging system. The automatic packaging system automatically packages the products after they are agglomerated.

[0024] A gas scrubbing tower 3 is connected to one side of the cooling chamber 2. The gas scrubbing tower 3 is used to receive the processed gas output from the cooling chamber 2. The gas scrubbing tower 3 is connected to a DMC cooling circulation device 301. The DMC cooling circulation device 301 is used to dissolve solid particles and chlorine in the processed gas in the gas scrubbing tower 3 to obtain a processed liquid. The acidic gas in the processed gas is discharged through the gas scrubbing tower 3.

[0025] The DMC cooling circulation device 301 includes a circulation pump 3011, a circulation cooler 3012, and a DMC inlet 3013. The circulation pump 3011 is connected to the bottom of the scrubbing tower 3 and is used to extract a portion of the processed liquid for circulation. The circulation cooler 3012 is located between the output end of the circulation pump 3011 and the inlet of the scrubbing tower 3. The DMC inlet 3013 is connected to one side of the circulation cooler 3012 and is used to cool a portion of the processed liquid and the DMC liquid input through the DMC inlet 3013. The processed gas from the cooling chamber 2 contains solid particles. In order to recover this material and the chlorine in the processed gas, a scrubbing tower 3 with DMC as the spray medium is set up. After the processed gas comes into contact with DMC in the tower, the solid particles and chlorine dissolve in the DMC. Most of the dissolved liquid in the scrubbing tower 3 is recycled. The circulation pipeline is equipped with a circulation cooler 3012 to keep the circulating liquid at about 5°C to ensure absorption efficiency.

[0026] A gas phase condenser 303 is connected to the top of the gas scrubbing tower 3. The output end of the gas phase condenser 303 is connected to a reflux tank 304. The bottom of the reflux tank 304 is connected to the gas scrubbing tower 3. The gas phase condenser 303 is used to condense the acidic gas in the gas scrubbing tower 3 and store the DMC in the acidic gas in the reflux tank 304. The remaining acidic gas is discharged through the reflux tank 304. The remaining acidic gas is condensed and enters the reflux tank 304. After removing the DMC in the gas phase, it enters the treatment device outside the boundary through the reflux tank 304.

[0027] The bottom of the gas scrubbing tower 3 is also equipped with a discharge pump 302, which is connected to the reactor. The discharge pump 302 is used to pump the treated liquid in the gas scrubbing tower 3 into the reactor as a reaction raw material.

[0028] Working principle: Solidified light from the reactor at around 88°C is transported to the spray tank 1 via the second conveying pipeline 102 with a heat-conducting oil jacket. After all the solidified light has entered the spray tank 1, hot nitrogen heated by the nitrogen heater 103 is injected into the spray tank 1, which transports the solidified light in the tank to the nozzle 1011 of the guide hood 202 in the cooling chamber 2. The nozzle 1011 in the guide hood 202 sprays the material out. The small droplets after spraying come into contact with the cold air transported by the cooling fan 203 and are rapidly cooled. The acidic gas dissolved in the material is quickly discharged to the gas scrubbing tower 3. The sprayed particulate material is forced to settle to the bottom conveyor belt 201, and the solid particles on the conveyor belt 201 enter the automatic packaging system.

[0029] After the acidic gas comes into contact with DMC inside the tower, the solid particles and chlorine dissolve in the DMC. The remaining acidic gas is condensed and refluxed to remove the DMC in the gas phase before entering the treatment device outside the boundary for processing. Most of the DMC in the gas scrubbing tower 3 is recycled and pumped by the circulation pump 3011 to the circulation cooler 3012 and then fed back into the gas scrubbing tower 3. The circulation cooler 3012 keeps the circulating DMC at about 5°C. Another part of the DMC containing dissolved solid particles and chlorine is pumped by the discharge pump 302 to the reactor as a reaction feedstock.
