Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of production devices for chlorinated environmental protection plasticizers in organic chemical products, and particularly relates to a chlorine purification device in the production of chlorinated environmental protection plasticizers. Technical Background
[0002] The production of existing chlorinated plasticizers generally uses chlorine to react with fatty acid methyl esters. Chlorine is transported through a chlorine pipeline and enters a reaction kettle to react with fatty acid methyl esters. As the use time of this chlorine pipeline continues to extend, rust will naturally form on the inner wall of the pipeline. Under the action of the flowing chlorine, these rusts will flake off and enter the reaction kettle along with the movement of chlorine. The rust mixed in the chlorine will cause the fatty acid methyl ester in the reaction to change color and reduce the product quality. Summary of the Invention
[0003] The purpose of the utility model is to provide a chlorine purification device in the production of chlorinated environmental protection plasticizers with good chlorine purification effect, simple and compact structure, low manufacturing and maintenance costs, and reliable use, so as to solve the problem that the rust of the chlorine pipeline in the prior art enters the reaction kettle along with chlorine and causes the fatty acid methyl ester in the reaction to change color and affect the product quality.
[0004] To achieve the above purpose, the chlorine purification device in the production of chlorinated environmental protection plasticizers of the utility model includes a filter cylinder body 6, with a chlorine outlet 1 at the top, a chlorine inlet 2 at one side of the bottom, a baffle plate 3 with a plurality of evenly distributed holes in the upper middle part of the body, and a support plate 4 with a plurality of evenly distributed holes in the lower middle part. The space between the baffle plate 3 and the support plate 4 is filled with a glass fiber mass 5; this device is installed adjacent to the reaction kettle.
[0005] After filling the gap between the perforated baffle plate 3 and the perforated support plate 4 with the glass fiber mass 5, the perforated support plate 4 can ensure that the glass fiber mass 5 does not block the chlorine inlet 2, and the perforated baffle plate 3 can ensure that the glass fiber mass 5 does not block the chlorine outlet 1.
[0006] The chlorine purification device in the production of chlorinated environmental protection plasticizers of the utility model has the following technical characteristics and beneficial effects:
[0007] 1. It can effectively filter and remove rust, thereby purifying chlorine, avoiding the rust entering the reaction kettle along with chlorine and causing the fatty acid methyl ester in the reaction to change color, and ensuring the product quality;
[0008] 2. The support plate 4 can ensure that the glass fiber mass 5 does not block the chlorine inlet 2, and the baffle plate 3 can ensure that the glass fiber mass 5 does not block the chlorine outlet 1, with reliable use.
[0009] 3. The whole device has a simple and compact structure, low manufacturing cost, and convenient and efficient operation. Brief Description of the Drawings
[0010] Figure 1It is a schematic structural diagram of the chlorine purification device in the production of the chlorinated environmental protection plasticizer of the present utility model.
[0011] Reference numerals: chlorine gas outlet 1, chlorine gas inlet 2, baffle plate 3, support plate 4, glass fiber mass 5, filter cartridge body 6. Specific embodiments
[0012] The following further describes in detail the specific embodiments of the chlorine purification device in the production of the chlorinated environmental protection plasticizer of the present utility model with reference to the accompanying drawings.
[0013] Figure 1 As shown, the chlorine purification device in the production of the chlorinated environmental protection plasticizer of the present utility model includes a filter cartridge body 6, with a chlorine gas outlet 1 at its top and a chlorine gas inlet 2 on one side of the bottom. Inside the body, a baffle plate 3 with multiple evenly distributed holes is provided in the upper middle part, and a support plate 4 with multiple evenly distributed holes is provided in the lower middle part. The space between the baffle plate 3 and the support plate 4 is filled with a glass fiber mass 5; the device is installed adjacent to the reaction kettle.
[0014] Using the above chlorine purification device in the production process of the chlorinated environmental protection plasticizer, the device is installed adjacent to the reaction tower. When chlorine gas passes through the glass fiber mass 5, since rust is granular, it will be adsorbed by the glass fiber mass 5, thus playing a role in filtering and removing rust, avoiding the discoloration of fatty acid methyl ester in the reaction caused by rust entering the reaction kettle with chlorine gas, and ensuring the product quality.
