Description

Technical Field

[0001] This utility model belongs to the field of carbonylation production technology, and in particular relates to a dust removal device for preparing carbonylation raw material CO. Background Technology

[0002] In the production of nickel carbonylation and iron carbonylation, CO is a crucial raw material for the carbonylation reaction. After large particles are removed by washing with water in a washing tower, crude CO prepared from coke in a CO launcher still contains small particles. These small particles must be removed before entering the desulfurization and adsorption dust removal process to meet process requirements for the next stage. Therefore, it is urgently necessary to add a dust removal device to the crude CO process before the water washing tower outlet and before the desulfurization and adsorption dust removal process to remove small particles from the crude CO. Utility Model Content

[0003] The purpose of this invention is to provide a dust removal device for the production of carbonyl raw material CO, which can remove small particulate impurities that still exist after filtration of the raw material CO during the carbonylation reaction process, so as to meet the production process requirements.

[0004] The technical solution adopted in this utility model is as follows:

[0005] A dust removal device for producing carbonyl feedstock CO includes a support, a shell, a gas separator plate, a tube bundle, a water outlet plate, an air inlet, an air outlet, an explosion-proof port, a cathode, an insulation box, a hanging rod, a cathode beam, a water inlet, a purge port, a wind baffle plate, a manhole, a steam inlet, a condensate outlet, a temperature measuring port, and a sewage outlet.

[0006] The support is connected to the bottom of the housing, and three insulation boxes are arranged above it. Each insulation box has a steam inlet, a condensate outlet, and a temperature measuring port on its side wall. The cathode is located inside the insulation box, and a hanging rod is connected below the cathode. The cathode beam is connected below the hanging rod. A wind baffle is arranged on the hanging rod. The tube bundle is located inside the housing, and a water outlet plate is arranged between the tube bundles. An air inlet is arranged on the lower side wall of the housing, and a gas separator is arranged below the tube bundle inside the housing. An air outlet is arranged directly above the housing, and a water inlet and a purge port are arranged on the upper side wall. The water inlet is connected to a fresh water pipe, and the purge port is connected to a nitrogen pipe. A drain outlet is arranged below the housing.

[0007] Preferably, the manhole and the explosion-proof opening are provided at both the upper and lower positions of the side wall of the housing.

[0008] Preferably, a thermometer is placed at the temperature measuring port to monitor the temperature inside the insulation box at any time.

[0009] Preferably, the bottom of the support is inclined towards the sewage outlet.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0011] After being washed with water to remove large particles, the crude CO gas containing small particles enters the device through the inlet. The cathode emits electrons downward through the cathode beam of the suspension rod. The electrons carry the charged small particulate impurities in the gas to the bottom of the shell through the tube bundle, thus completing the small particle dust removal. After subsequent desulfurization and other original processes, the purity of CO is further improved, which is conducive to the smooth progress of the carbonylation reaction.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0018] Please refer to Figures 1-4This device is added to the existing production process. It includes a support 1, a shell 2, a gas separator 3, a tube bundle 4, a water outlet 5, an air inlet 6, an air outlet 7, an explosion-proof port 8, a cathode 9, an insulation box 10, a hanging rod 11, a cathode beam 12, a water inlet 13, a purge port 14, a wind baffle 15, a manhole 16, a steam inlet 17, a condensate outlet 18, a temperature measuring port 19, and a drain port 20. The support 1 is connected to the bottom of the shell 2, and three insulation boxes 10 are installed on top. Each insulation box 10 has a steam inlet 17, a condensate outlet 18, and a temperature measuring port 19 on its side wall. Steam is introduced into the steam inlet 17 of the insulation box 10, generating condensate which flows out from the condensate outlet 18, keeping the cathode inside the insulation box dry and ensuring insulation. The insulation box is also equipped with a temperature measuring port 19 to hold a thermometer for monitoring the temperature inside the insulation box. The insulating box 10 contains a cathode 9, with a suspension rod 11 connected below it. A cathode beam 12 is connected below the suspension rod 11, and a baffle plate 15 is mounted on the suspension rod 11. The housing 2 contains tube bundles 4, with water outlet plates 5 positioned between the tube bundles 4. An air inlet 6 is located on the lower side wall of the housing 2, and a gas separator 3 is located below the tube bundles 4 inside the housing 2. Dust-laden CO enters the device through the air inlet 6 and then passes through the gas separator 5, ensuring uniform gas distribution within the device and achieving better dust removal. An air outlet 7 is located at the top of the housing 2, and a water inlet 13 and a purge port 14 are located on the upper side wall. The water inlet 13 connects to a fresh water pipe, and the purge port 14 connects to a nitrogen pipe. A drain port 20 is located at the bottom. Manholes 16 and explosion-proof openings 8 are located on the upper and lower sides of the housing 2. The bottom of the support 1 is sloped towards the drain port 20, allowing cleaning wastewater to flow out along the slope after dust removal, preventing liquid accumulation within the device.

[0019] The working principle of this device is as follows: After large particles are removed by water washing, the coarse CO gas containing small particles enters the device through the inlet. As it moves upward through the tube bundle 4, the cathode 9 emits electrons downward through the suspension rod 11 and the cathode beam 12. The tube bundle 4 carries the charged small particulate impurities in the gas to the bottom of the shell 2, thus completing the small particle dust removal. The coarse CO gas after dust removal enters the desulfurization adsorption dust removal through the outlet 7 at the top.

[0020] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. For those skilled in the art, changes and variations are possible with this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
