Description

Technical Field

[0001] The invention relates to the technical field of atomization, in particular to a hazardous waste atomization device for producing 2-chloro-5-chloromethylpyridine. Background Art

[0002] 2-Chloro-5-chloromethylpyridine is an organic compound, an important intermediate for the synthesis of pesticides and medicines, and an important raw material for the synthesis of high-efficiency and low-toxic pesticide imidacloprid. It has strong allergenicity. In industry, 2-chloro-5-methylpyridine is often obtained by side-chain chlorination of 2-chloro-5-methylpyridine in the presence of a catalyst; 2-chloro-5-methylpyridine and a solvent are added to a reaction axe, a catalyst is added, and the reaction is refluxed and chlorine is passed through.

[0003] A large amount of harmful waste gas will be generated in the preparation process of 2-chloro-5-chloromethylpyridine. If these waste gases are discharged at will without subsequent treatment, they are easy to pollute the external environment; the hazardous waste atomization device mainly uses atomized atomization liquid to absorb and purify the waste gas, and the impurities are filtered through the filter plate before the waste gas enters the atomization device, and then it is neutralized and absorbed when entering the atomization chamber. After a long time, the filter plate is mainly cleaned manually to avoid clogging, and then it is cleaned by water injection. The manual cleaning process is time-consuming and labor-intensive, and the operating efficiency is low. The waste liquid neutralized and absorbed by atomization is directly discharged, and the waste liquid cannot be used to clean the filter plate. In addition, the atomization structure in the existing atomization device is fixed, resulting in fixed contact between the rising waste gas and the mist, and the atomization contact effect is reduced.

[0042] See also Figure 6 and Figure 7 The bottom end of the rotating rod 22 extends through and extends to the outside of the bottom of the first filter screen plate 20.

[0044] See also Figure 5 and Figure 8A filter plate 34 is fixedly installed on the top of the conical frame 30 by bolts, and a plurality of drainage holes 35 are evenly opened on the outer periphery of the top of the conical frame 30 to achieve drainage. A plurality of atomizing nozzles 48 are evenly installed at the bottom center of the atomizing movable seat 40 by bolts to atomize the neutralizing liquid to contact the exhaust gas.

[0045] Working principle: The harmful waste gas generated in the preparation of 2-chloro-5-chloromethylpyridine is injected into the base plate 11 through the air inlet pipe 14, the waste gas rises in the atomizing tower body 10 and passes through the first filter screen plate 20 for filtering, and then passes through the second filter screen plate 31 for further filtering to remove impurities in the waste gas, and then the waste gas is concentrated into the cone frame 30, and then discharged through the filter plate 34 on the top of the cone frame 30, and the waste gas discharged from the filter plate 34 is atomized, absorbed and purified by the atomizing nozzle 48 under the atomizing movable seat 40, and the harmful gas in the waste gas is purified, absorbed or neutralized;

[0046] During absorption purification, the first rotating shaft 51 drives the connecting seat 52 to rotate stably on the bearing of the supporting frame 50, and the arc rod 47 on the connecting seat 52 will rotate synchronously with the first rotating shaft 51. When the arc rod 47 rotates to both sides of the rotating column 42, the rotating block 44 and the rotating column 42 are driven to swing left and right through the U-shaped rotating seat 45. When the arc rod 47 rotates to the upper and lower ends of the rotating column 42, the U-shaped rotating seat 45 moves up and down on the outside of the rotating block 44, and at this time, the atomizing movable seat 40 is located at the top center of the conical frame 30. When the arc rod 47 moves on the right side of the rotating column 42, the atomizing movable seat 40 swings 30° to the left. Similarly, when the arc rod 47 rotates on the left side of the rotating column 42, the atomizing movable seat 40 swings 30° to the right (refer to the attached Figure 4 ), the atomized liquid under the atomizing nozzle 48 is in swinging contact with the exhaust gas, and the atomized liquid forms an S-shaped curve in the space after being sprayed, so as to avoid direct convection contact between the exhaust gas and the atomized liquid in the atomizing tower body, thereby improving the atomization effect of the exhaust gas;

[0047] During the absorption and purification, the second rotating shaft 53 drives the second bevel gear 24 to rotate, and the meshing of the second bevel gear 24 drives the first bevel gear 23 and the rotating rod 22 to rotate stably on the bearing, so that the first cleaning plate 21 on the rotating rod 22 brushes the top of the first filter screen plate 20, and the second cleaning plate 32 on the rotating rod 22 brushes the bottom of the second filter screen plate 31 back and forth, with good cleaning effect and stable structure, and the impurities on the filter screen plate are brushed and cleaned, thereby improving the efficiency of exhaust gas purification and absorption;

[0048] The third bevel gear 66 is driven to move by the meshing of the fourth bevel gear 25 at the bottom of the rotating rod 22, and the third bevel gear 66 drives the rotating rod 65 to perform stable rotational motion through the bearing on the fixed plate 64. The arc cam 67 on the rotating rod 65 pushes the movable plate 60 connected to the telescopic spring 61 at intervals, so that the telescopic spring 61 is stretched and stored. When the arc cam 67 disengages from the base block 68 on the movable plate 60, the movable plate 60 is instantly reset, and the bottom of the first filter plate 20 is vibrated by the movable rod 62 and the movable block 63 to avoid clogging of the first filter plate 20 by impurities, thereby improving the exhaust gas purification effect, and the structure is simple and stable; the first rotating shaft 51 and the second rotating shaft 53 are driven to rotate synchronously by the first gear 54, the second gear 55 and the chain 56, and the structural connection is stable.

[0049] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
