Description

Technical Field

[0001] The utility model relates to the technical field of chlorinated paraffin production, in particular to a single-carbon chain chlorinated paraffin production device. Background Art

[0002] Chlorinated paraffin is a chlorinated derivative of paraffin hydrocarbons with the advantages of low volatility, flame retardancy, good electrical insulation and low price. It can be used as a flame retardant and auxiliary plasticizer for polyvinyl chloride. It is widely used in the production of cable materials, floor materials, hoses, artificial leather, rubber and other products, as well as additives for coatings, plastic tracks, lubricants, etc.

[0003] There are many existing technologies for chlorinated paraffin production equipment, such as:

[0004] Chinese patent announcement number CN216024897U discloses a chlorinated paraffin reactor, which includes a reactor body, a heat exchanger and a circulating pump. The cooling port on the side wall of the bottom of the reactor body, the heat exchanger, the circulating pump and the discharge port at the bottom of the reactor body are sequentially connected through a circulating pipeline. The side wall of the reactor body is located between the cooling port and the discharge port and is also provided with a circulating material inlet. An ejector is provided on the circulating material inlet. The inlet of the ejector is connected to the discharge end of the circulating pipeline located at the circulating pump through a feed pipe. The negative pressure outlet of the ejector is connected to the tail gas discharge pipe at the top of the reactor body. The utility model delivers part of the material into the reactor body from the circulating material inlet through a circulating pump, and utilizes the negative pressure generated by the negative pressure outlet of the ejector to re-send part of the tail gas in the tail gas discharge pipe into the reactor body for reaction, so that part of the chlorine in the tail gas re-enters the reactor body for reaction, thereby reducing the chlorine content in the tail gas.

[0005] It can be seen from this that after chlorinated paraffin is produced, it is necessary to clean the crude material, the hydrochloric acid generated in the reaction needs to be processed as a by-product, and the method of washing is usually used to separate hydrochloric acid from chlorinated paraffin, in the process of preparation, if a large amount of paraffins are piled up together, then the paraffin at the bottom is difficult to contact with chlorine, causing insufficient reaction so that the yield rate decreases, and the by-product hydrochloric acid has strong corrosiveness and is harmful to the human body, and the existing chlorinated paraffin production device cannot automatically separate it from the water dissolved with hydrochloric acid after washing the product, such as a kind of chlorinated paraffin reactor proposed in the above-mentioned patent, it mainly includes kettle and circulating pump, after chlorine enters the kettle, the paraffin accumulated at the bottom of the kettle cannot be fully contacted with chlorine. In addition, subsequent processing is not carried out for the obtained crude product.

[0006] In view of this, we propose a single-carbon chain chlorinated paraffin production device, which uses a spiral stirring paddle set in the reactor to bring the paraffin accumulated at the bottom of the reactor to the upper part, so that it can fully contact and react with the chlorine in the reactor. In addition, the set feeding component and cleaning component cooperate with each other, so that after the crude chlorinated paraffin product is cleaned, the product can be automatically separated from the water dissolved in hydrochloric acid.
