Abstract
The utility model relates to a dechlorination device in the process of producing chlorinated paraffin. A tail gas exhaust pipe of a chlorinated reaction kettle is communicated with a dechlorination kettle, the dechlorination kettle is connected to a liquid wax input pipe, the upper end of the dechlorination kettle is provided with a hydrogen chloride outlet, and the lower end of the dechlorination kettle is connected with the dechlorination kettle through a transferring pump. With the adoption of the dechlorination device in the process of producing chlorinated paraffin, the utilization rate of chlorine and the purity of hydrogen chloride gas can be improved, impurities in liquid wax can be eliminated, the product quality of the chlorinated paraffin can be improved, and considerable economic benefit and practicability are available. With the adoption of the technology, the chlorine content in hydrogen chloride is less than or equal to 0.1%, the purity of the hydrogen chloride gas is improved so as to meet the use requirement of a chlorosulfonic acid device, the quality of the liquid wax is improved at the same time, and the comprehensive product quality is beneficially improved.
Description
Technical field:
The utility model relates to the device that removes the chlorine in the hydrogen chloride gas in the chlorinated paraffin wax production process.
Background technology:
In the chlorinated paraffin wax chlorination reaction process, there is part chlorine excessive, the one, cause chlorine consumption big, the 2nd, the reaction chlorinated exhaust needs to absorb with liquid caustic soda, increased production cost, the 3rd, pollute surrounding environment, hydrogen chloride can be sent to the chlorosulfonic acid device and produce chlorosulfonic acid, but purity, the chlorinity of chlorine are had relatively high expectations, and the hydrogen chloride that the conventional chlorinated paraffin wax mode of production is produced can not satisfy the production of chlorosulfonic acid.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned technical deficiency, and a kind of liquid wax dechlorination device is provided.
Dechlorination device in a kind of chlorinated paraffin wax production process, the exhaust pipe of chlorination reaction still is communicated with the dechlorination still, the dechlorination still is connected with liquid wax input pipe, the hydrogen chloride outlet is established in the upper end of dechlorination still, the lower end links to each other with the chlorination reaction still by transfering material pump, and annular gas distributor and feed liquor tetrafluoro bend pipe are installed in the described dechlorination still.
The hydrogen chloride outlet of described dechlorination still upper end links to each other with the chlorosulfonic acid device.
The chlorinated exhaust that chlorination reaction is produced feeds dechlorination reaction in the hot liquid wax, and the gas behind the dechlorination reaction is got rid of from the hydrogen chloride outlet, and the liquid that contains liquid wax of generation is got rid of the raw material that the back conduct continues chlorination reaction.
Successive reaction under described dechlorination reaction pressure 0.02-0.03MPa, temperature 70-90 ℃ and the light-initiated condition.
Gas behind the described dechlorination reaction enters the chlorosulfonic acid production system.
Liquid wax after the heating is squeezed in the dechlorination still continuously by certain flow, and the chlorinated exhaust with the generation in the chlorinated paraffin wax production process feeds the dechlorination still again.For improving removal effect, annular gas distributor and feed liquor tetrafluoro bend pipe are installed in still.Under certain pressure, temperature and light-initiated condition, purification hydrogen chloride gas and improve the quality of liquid wax.Contain hydrogen chloride, chlorine and steam in the chlorinated exhaust.Hydrogen chloride is emitted in chlorine in the tail gas, wax oil reaction, and chlorine is deviate from, and has improved the purity of tail gas hydrogen chloride; Because the still temperature is than higher, water vapor condensation is a moisture in the tail gas, behind the absorbing hydrogen chloride, forms hydrochloric acid (concentration reaches more than 33%), is sunken to the bottom of wax oil automatically.Moisture in the wax oil is also because the temperature height is separated.Generate ferric trichloride behind iron ion and chlorine, the hcl reaction, because the density of ferric trichloride own is big, soluble in water, its solubility in wax oil is much smaller than the solubility in hydrochloric acid, so ferric trichloride is easy to be extracted from wax oil by hydrochloric acid.The reaction of aromatic hydrocarbons and chlorine, basic nitrogen and hydrogen chloride, product density is all greater than 1, and this moment, oily density was about 0.8, so be easy to be sunken to the bottom of wax oil, the bottom separator is discharged system by sewage draining exit, wax oil through so handling enters system again, has improved the purity of hydrogen chloride and liquid wax, helps the lifting of product quality.
The utility model is two separating substances technology of gas gas, can improve the utilization rate of chlorine and the purity of hydrogen chloride gas, can remove the impurity in the liquid wax again, improves the product quality of chlorinated paraffin wax, has considerable economic and practicality.
The utilization of this technology makes content≤0.1% of chlorine in the hydrogen chloride, has improved hydrogen chloride gas purity to satisfy the use of chlorosulfonic acid device, improves the quality of liquid wax simultaneously, helps the lifting of product comprehensive quality.
