Abstract

This utility model discloses a safe coal chemical distillation device, belonging to the field of coal chemical distillation technology. The device includes a main body comprising a reactor and a distillation column. The reactor includes a lower tank and an upper tank. The upper tank has an internal cavity. An exhaust pipe connecting the upper tank cavity to the distillation column cavity is formed on the top wall of the upper tank. A collection section is formed on the bottom wall of the upper tank, and a collection trough communicating with the internal cavity is formed on the top wall of the collection section. Multiple baffles are formed along the circumference of the exhaust pipe on the inner wall of the internal cavity, with drainage gaps between adjacent baffles.

Description

Technical Field

[0001] This utility model relates to the field of coal chemical distillation technology, specifically to a safe coal chemical distillation device. Background Technology

[0002] Coal chemical industry refers to the process of using coal as raw material and chemically processing it into gaseous, liquid, and solid fuels and chemicals. It mainly includes coal gasification, liquefaction, dry distillation, as well as tar processing and calcium carbide acetylene chemical industry. In the coal chemical processing process, the chemical structure of the organic matter in coal is a macromolecular structure with aromatic-based fused rings as the core unit, connected by bridging bonds, and containing various functional groups. Through thermal processing and catalytic processing, coal can be converted into various fuels and chemical products. Coal chemical processing requires the use of coal chemical distillation equipment.

[0003] Existing distillation apparatuses include a reaction vessel and a distillation column. The reaction vessel is located at the bottom of the distillation column, and the reaction vessel and the inner cavity of the distillation column are vertically connected. The reaction vessel is used to heat the coal product mixture to generate steam, and the distillation column is used to condense and collect the steam generated in the reaction vessel. However, when the steam is fed into the distillation column from the reaction vessel, it must be transported through pipelines. This causes some steam to come into contact with the inner wall of the pipeline and form liquid water droplets prematurely. These liquid water droplets will flow back into the reaction vessel, resulting in resource waste and hindering the improvement of the distillation product recovery rate. At the same time, the condensate dissolves acidic gases such as hydrogen sulfide, which not only easily causes equipment corrosion, but also creates local negative pressure effects and water hammer effects after steam condensation, posing safety hazards. Improper operation, inadequate drainage, or inadequate emergency response can lead to safety accidents. Utility Model Content

[0004] This invention provides a safe coal chemical distillation device that overcomes some or all of the defects of the prior art.

[0005] According to the present invention, a safe coal chemical distillation device includes a main body, which includes a reactor and a distillation column. The reactor includes a lower tank and an upper tank. The upper tank has an inner cavity. An exhaust pipe is formed on the top wall of the upper tank, connecting the inner cavity of the distillation column to the inner cavity. A collection part is formed on the bottom wall of the upper tank, and a collection trough communicating with the inner cavity is formed on the top wall of the collection part. Multiple baffles are formed on the inner wall of the inner cavity, arranged circumferentially along the exhaust pipe. A flow-guiding gap is formed between adjacent baffles, which is used to guide liquid water droplets on the inner wall of the inner cavity to the collection trough for collection.

[0006] By setting an inner cavity inside the upper tank and setting multiple baffles along the circumference of the exhaust pipe on the inner wall of the inner cavity to form a flow-guiding gap, the steam that comes into contact with the exhaust pipe and the inner cavity in advance can be effectively guided into the collection tank as liquid water droplets, avoiding the liquid water droplets flowing back into the reactor and affecting the coal product mixture, thus improving the recovery rate and distillation effect of the distillation products.

[0007] Preferably, an inwardly recessed guide groove is formed on the side of the partition away from the inner wall of the cavity, and a guide surface corresponding to the collection groove is formed at the bottom wall of the guide groove.

[0008] The above structure allows liquid water droplets formed on the outer wall of one side of the inner wall of the partition cavity to be guided through the guide channel, and the water droplets can be guided into the collection tank for collection through the guide channel and the guide surface, thus improving the collection effect.

[0009] Understandably, the guide channel allows liquid water droplets that condense on the inner wall of the cavity to be quickly guided into the guide channel, reducing the time the water droplets stay on the outer wall of the partition.

[0010] Preferably, a collection pipe is formed on the outer wall of the collection section, which communicates with the collection tank, and the collection pipe is used to drain the liquid water in the collection tank.

[0011] The above structure allows liquid water droplets in the collection tank to be discharged in a timely manner, preventing them from accumulating in the collection tank.

[0012] Preferably, a recess is formed at the bottom wall of the collection tank corresponding to the collection pipe, and an inclined portion is formed at the bottom wall of the collection tank in the direction of the recess.

[0013] The above structure allows the liquid water collected in the collection tank to better accumulate at the inclined section, thereby improving the fluidity of the liquid water collected in the collection tank.

[0014] Preferably, the bottom wall of the inner wall of the collecting tube is lower than the bottom wall of the recess, and the recess is inclined towards the collecting tube.

[0015] The above structure allows the liquid water that accumulates at the sloping part to be guided into the collection tank along the concave part for discharge, further improving the water flow and thus improving drainage efficiency.

[0016] Preferably, the top wall of the collection tank has an inclined surface corresponding to the guide surface, and the top wall of the baffle has a guide portion that is inclined outward along the circumference of the exhaust pipe.

[0017] The inclined surface design allows water droplets flowing down the guide channel and inner wall of the cavity to be better guided into the collection tank for collection. The inclined surface design also allows water droplets generated on the inner wall of the exhaust pipe to flow into the collection tank more effectively, thus improving the collection efficiency.

[0023] Example 1

[0024] Please see Figure 1-4 This embodiment provides a safe coal chemical distillation device, which includes a device body 100. The device body 100 includes a reactor and a distillation column. The reactor includes a lower tank and an upper tank 110. An inner cavity 210 is formed inside the upper tank 110. An exhaust pipe 140 is formed on the top wall of the upper tank 110, connecting the inner cavity of the distillation column and the inner cavity 210. A collection part 120 is formed on the bottom wall of the upper tank 110. A collection tank 310 communicating with the inner cavity 210 is formed on the top wall of the collection part 120. A plurality of baffles 220 are formed on the inner wall of the inner cavity 210, arranged circumferentially along the exhaust pipe 140. A flow-guiding gap 230 is formed between adjacent baffles 220. The flow-guiding gap 230 is used to guide liquid water droplets on the inner wall of the inner cavity 210 to the collection tank 310 for collection.

[0025] The safe coal chemical distillation device of this embodiment, by setting an inner cavity 210 inside the upper tank 110, and setting multiple baffles 220 along the circumference of the exhaust pipe 140 on the inner wall of the inner cavity 210 to form a flow-guiding gap 230, can effectively guide the steam that comes into contact with the exhaust pipe 140 and the inner cavity 210 in advance to form liquid water droplets and guide them to the collection tank 310. This avoids the liquid water droplets flowing back into the reaction vessel and affecting the coal product mixture, thereby improving the recovery rate and distillation effect of the distillation products.

[0026] In this embodiment, a recessed guide groove 360 ​​is formed on the side of the partition 220 away from the inner wall of the inner cavity 210, and a guide surface corresponding to the collection groove 310 is formed at the bottom wall of the guide groove 360.

[0027] With the above structure, liquid water droplets formed on the outer wall of one side of the inner wall of the cavity 210 of the partition 220 can be guided through the guide groove 360, and the water droplets can be guided into the collection tank 310 for collection through the guide groove 360 ​​and the guide surface, thereby improving the collection effect.

[0028] Understandably, the guide channel 360 allows the liquid water droplets that condense on the inner wall of the inner cavity 210 to be quickly guided into the guide channel 360, reducing the residence time of the water droplets on the outer wall of the partition 220.

[0029] In this embodiment, a collection pipe 130 communicating with the collection tank 310 is formed on the outer wall of the collection part 120. The collection pipe 130 is used to discharge liquid water in the collection tank 310.

[0030] The above structure allows liquid water droplets in the collection tank 310 to be discharged in a timely manner, preventing them from accumulating in the collection tank 310.

[0031] In this embodiment, a recess 330 is formed on the bottom wall of the collection tank 310 corresponding to the collection tube 130, and an inclined portion 340 is formed on the bottom wall of the collection tank 310 in the direction of the recess 330.

[0032] The above structure allows the liquid water collected in the collection tank 310 to better accumulate at the inclined section 340, thereby improving the fluidity of the liquid water collected in the collection tank 310.

[0033] In this embodiment, the bottom wall of the inner wall of the collection tube 130 is lower than the bottom wall of the recess 330, and the recess 330 is inclined towards the collection tube 130.

[0034] The above structure allows the liquid water that accumulates at the inclined section 340 to be guided into the collection tank 310 along the concave section 330 for discharge, further improving the fluidity of the water and thus improving the drainage efficiency.

[0035] In this embodiment, a slope 320 corresponding to the guide surface is formed on the top wall of the collection tank 310, and a guide portion 350 is formed on the top wall of the partition plate 220, which is inclined outward along the circumference of the exhaust pipe 140.

[0036] By setting the inclined surface 320, the water droplets flowing down along the guide groove 360 ​​and the inner wall of the inner cavity 210 can be better guided into the collection tank 310 for collection. By setting the inclined surface 320, the water droplets generated on the inner wall of the exhaust pipe 140 can flow into the collection tank 310 along the inner cavity 210, thus improving the collection effect.
