Description

Technical Field

[0001] The invention relates to the technical field of chemical equipment, and in particular to a skid-mounted integrated device for producing unpowered circulating continuous chlorinated paraffin. Background Art

[0002] Chlorinated paraffin is an important industrial raw material, widely used in industries such as polyvinyl chloride, polyurethane, rubber and plastic, and oil products. Its production has gradually transitioned from the intermittent production of adding liquid wax to a reactor with extremely low production efficiency and then introducing chlorine gas to chlorinate the generated chlorinated paraffin to a relatively high efficiency continuous production method. The invention patent application with Chinese patent application number 02148592.5 and publication number CN1424381A discloses a continuous chlorinated paraffin production device, in which the raw material chlorine gas inlet of the device is set at the top of each reactor. Therefore, when producing chlorinated paraffin, there are problems such as uneven chlorine distribution and the phenomenon of "black material" in the chlorination reaction tower that cannot be effectively solved. The invention patent application with Chinese patent application number 200610025410.7 and publication number CN1824737A discloses a method for continuous production of chlorinated paraffin. The production method solves the problems of uneven chlorine distribution and "black material" in the chlorination reaction tower in the above patent application through the chlorinated paraffin production device used. The method is achieved by relying on the circulating pump arranged on each reactor constituting the reaction device to perform power forced circulation. However, the reaction device is provided with at least five stages of reactors. If any one of the circulating pumps of the five stages of reactors has a problem, it will still cause the "black material" problem of the reactor and serious environmental pollution problems. At the same time, the high-power circulating pump arranged in the device reaches 55kw / h, which is also not conducive to green environmental protection and increases production costs.

[0003] The above two chlorinated paraffin production technologies are both realized by connecting multiple reactors in sequence. Each reactor needs to be installed separately and needs to be adapted to each other, which undoubtedly increases the difficulty of installation.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] The purpose of the present invention is to provide a skid-mounted integrated device for the production of non-powered circulating continuous chlorinated paraffin to solve the problems existing in the prior art. Multiple chlorination reaction units and gas-liquid separation units are skid-mounted, integrated and installed in series to form continuous chlorinated paraffin production lines of different scales, which are easy to install and ensure stable operation, can overcome the "black material" problem of the reactor, and are beneficial to green environmental protection.

[0021] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1 As shown, this embodiment provides a non-powered circulating continuous chlorinated paraffin production skid-mounted integrated device, including a chlorination reaction tower 1, a gas-liquid separation mechanism 2 and a cooler 3. The chlorination reaction tower 1 includes two chlorination reaction units 4 and a gas-liquid separation unit 5 connected in sequence from bottom to top; in other embodiments, more than two chlorination reaction units 4 may be provided, such as 3-7 chlorination reaction units 4, which may be selected according to actual conditions; Each chlorination reaction unit 4 and the gas-liquid separation unit 5 is provided with a cooling jacket 6 outside, and cooling water is passed through the cooling jacket 6 for cooling. A chlorine gas inlet 7 is provided at the bottom of the chlorination reaction tower 1, and the chlorine gas inlet 7 is connected to a chlorine gas distributor 8 arranged inside the chlorination reaction tower 1. A liquid wax inlet 9 and a reactant outlet 10 are provided between the gas-liquid separation unit 5 and the adjacent chlorination reaction unit 4, and the liquid wax inlet 9 is connected to a liquid diffuser 11 arranged inside the chlorination reaction tower 1. A hydrogen chloride outlet 12 is provided at the top of the chlorination reaction tower 1, and the hydrogen chloride outlet 12 is connected to the inlet of the gas-liquid separation mechanism 2. The gas outlet of the gas-liquid separation mechanism 2 is connected to a tail gas treatment system 13, and the liquid outlet of the gas-liquid separation mechanism 2 is connected to a bottom reflux port 14 of the chlorination reaction tower 1; A photocatalytic energy source 15 is disposed on the outside of each chlorination reaction unit 4, wherein a group of photocatalytic energy sources 15 is disposed below the liquid diffuser 11 and adjacent to the liquid diffuser 11; A reactant circulation outlet 16 is provided in the middle and upper part of the overall structure formed by each chlorination reaction unit 4, and a circulating reactant inlet 17 is provided in the lower part. The inlet of the cooler 3 is connected to the reactant circulation outlet 16, and the outlet of the cooler 3 is connected to the circulating reactant inlet 17. The cooler 3 uses a large-diameter enamel disc cooler with a reinforced plate.

[0023] The liquid level height of the chlorination reaction tower 1 has a liquid pressure of at least 0.05MPa as the power source of the cooler 3. During the cooling process of the cooler 3, the material density increases by 50kg / m³ compared with the material density in the chlorination reaction tower 1. The liquid pressure at the top of the cooler 3 is combined with the gravity increased by 50kg / m³ at the bottom to achieve the effect of automatic circulation and cooling of the material, completely replacing the traditional mode relying on power circulation, and greatly reducing energy consumption.

[0024] Liquid paraffin continuously enters the chlorination reaction tower 1 from the liquid diffuser 11, is dispersed and precipitated to mix with the chlorine gas, and undergoes a chlorination reaction under the catalysis of the catalytic light source 18 (ultraviolet rays). After chlorination, it enters the gravity automatic circulation cooler 3. After cooling, the material automatically enters the chlorination reaction tower 1, is dispersed in the center of the chlorination reaction tower 1, and is mixed with the chlorine gas entering the chlorination reaction tower 1 to further undergo a chlorination reaction.

[0025] Chlorine enters the tower from the chlorine distributor 8, mixes with the circulating cooled material, and undergoes a chlorination reaction under the action of photocatalysis. The hydrogen chloride generated by the reaction enters the gas-liquid separation mechanism 2 from the upper part of the tower. After the hydrogen chloride and liquid wax mixture enters the gas-liquid separation mechanism 2, the separated liquid wax flows back to the chlorination reaction tower 1, and the hydrogen chloride gas enters the tail gas treatment system 13 for absorption and treatment. The reactants generated by the reaction are discharged from the reactant outlet 10 and enter the chlorination reaction tower 1 of the next-level skid-mounted integrated device to continue the chlorination reaction.

[0026] The device integrates a plurality of chlorination reaction units 4 and gas-liquid separation units 5 in series, and integrates a gas-liquid separation mechanism 2 and a cooler 3 on a chlorination reaction tower 1 to form continuous chlorinated paraffin production lines of different scales. Unlike the traditional technology, it is not necessary to adapt and install each reactor to each other. The skid-mounted integrated device reduces the difficulty of installation and is more convenient to install. The problem of unstable operation caused by the inability of traditional reactors to adapt and install will not occur. The skid-mounted integrated device can ensure stable operation after installation. Each chlorination reaction unit 4 and gas-liquid separation unit 5 is provided with a cooling jacket 6 outside, and the temperature in the chlorination reaction tower 1 can be controlled by the cooling jacket 6. In addition, by setting the cooler 3, the material in the chlorination reaction tower 1 can be circulated and cooled to further control the reaction temperature. The chlorine distributor 8 and the liquid diffuser 11 can disperse the chlorine and liquid wax to ensure the uniformity of the distribution of the chlorine and liquid wax, thereby overcoming the "black material" problem of the reactor and being beneficial to green environmental protection. At the same time, the cooler 3 can be circulated and cooled under unpowered conditions, without the need to install a high-power circulation pump, thereby reducing the production cost.

[0027] In this embodiment, two groups of photocatalytic energy sources 15 are provided on the outside of the bottom chlorination reaction unit 4, and one group of photocatalytic energy sources 15 is provided on the outside of the middle chlorination reaction unit 4. Each group of photocatalytic energy sources 15 includes three catalytic light sources 18, and the three catalytic light sources 18 are evenly distributed at intervals of 120° along the circumferential direction of the chlorination reaction unit 4, and each catalytic light source 18 controls an angle of 60°. The catalytic light wave energy uses the ionization energy wavelength of chlorine molecules. Among them, the photocatalytic energy source 15 on the outside of the middle chlorination reaction unit 4 is located below the liquid diffuser 11 and is arranged adjacent to the liquid diffuser 11. The three groups of photocatalytic energy sources 15 are arranged in layers along the height direction, and the adjacent two layers are staggered by 30° in the circumferential direction.

[0028] In this embodiment, a flat-panel sight glass corresponding to each catalytic light source 18 is disposed on the side wall of the chlorination reaction unit 4 , and the light source enters the chlorination reaction unit 4 through the flat-panel sight glass.

[0029] In this embodiment, the liquid diffuser 11 includes a horizontal pipe 19 and a vertical pipe 20 connected at a right angle of 90°, the horizontal pipe 19 is connected to the chlorine gas inlet 7, the vertical pipe 20 is arranged in the middle of the chlorination reaction unit 4, and a plurality of dispersion holes are evenly opened on the side wall of the vertical pipe 20, and the axis of each dispersion hole is perpendicular to the axis of the chlorination reaction unit 4. The liquid diffuser 11 is made of temperature-resistant reinforced high-resin content FRP, the outer diameter of the inlet is slightly smaller than the diameter of the feed port of the chlorination reaction tower 1, and the height is designed according to the height ratio of the chlorination reaction tower 1.

[0030] In this embodiment, the chlorine gas distributor 8 includes an upper plate and a lower plate, which are connected to each other to form a sandwich structure, and a plurality of gas outlet holes are arranged on the upper plate and the lower plate. The chlorine gas distributor 8 is made of heat-resistant reinforced high-resin content FRP, the length is the same as the diameter of the chlorination reaction tower 1, and the bending strength reaches more than 300MPa.

[0031] In this embodiment, the hydrogen chloride gas generated by the chlorination reaction is separated from the liquid material by bubbling in the gas-liquid separation unit 5, the liquid material remains in the chlorination reaction tower 1, and the hydrogen chloride gas rises and enters the gas-liquid separation mechanism 2. The volume of the gas-liquid separation unit 5 accounts for 10% to 15% of the volume of the chlorination reaction tower 1. The chemical reaction conditions require sufficient chlorine gas retention and liquid wax, sufficient reaction space and temperature, and a smaller residence space (i.e., a smaller volume) destroys the tower explosion reaction conditions, which has an excellent effect on preventing the tower explosion from causing black material accidents.

[0032] In this embodiment, the gas-liquid separation mechanism 2 is a gas-liquid cyclone separator. It is made of temperature-resistant reinforced FRP, and its hydrogen chloride inlet is tangential entry. The gas-liquid cyclone separator is provided with gas phase, liquid phase guide barrel, cyclone vortex stabilizing plate, hydrogen chloride gas outlet, semi-finished product liquid phase reflux port, and its specific structure belongs to the existing conventional technology and will not be described here.

[0033] In this embodiment, the chlorination reaction tower 1 is made of enamel material and has a high-to-diameter ratio (the ratio of the tower height to the inner diameter) design to increase the gas phase travel channel and constrain the gas phase diffusion within the tower diameter range, which is very beneficial to the chemical reaction between the gas phase and the liquid phase, and is beneficial to the thermal balance of the chlorination reaction, avoiding the occurrence of local explosive reaction hotspots in the chlorination reaction tower 1 and causing a decrease in product quality.

[0034] The production process of this device is as follows: Chlorine enters the bottom of the chlorination reaction tower 1 from the chlorine distributor 8, and the chlorine gas flow rises through the air outlet on the upper plate. The downwardly designed air outlet allows the impact of the chlorine gas flow to reach the bottom of the chlorination reaction tower 1. Chlorine bubbles begin to rise, and the liquid wax entering from the liquid diffuser 11 is evenly dispersed by the rising air flow to participate in the chlorination reaction in the tower. The chlorine bubbles rise to the first group of light wave energy zones (the corresponding position of the photocatalytic energy source 15), and the energy dissociates the chlorine molecules into chloride ions, and begins a chain replacement reaction with the liquid wax, completing the first photocatalysis and generating heat, and the escaped chlorine molecule bubbles continue to rise; the escaped chlorine molecule bubbles rise to the second group of light wave energy zones, and the light wave energy dissociates the chlorine molecules into chloride ions, and continues a chain replacement reaction with the liquid wax, completing the second photocatalysis, and generating enough heat again to maintain the chlorination reaction temperature; after two photocatalysis, the chlorination reaction is intense, releasing a large amount of reaction. The heat of reaction cannot be removed by cooling the cooling jacket 6 with water. The device further controls the reaction temperature by circulating cooling under unpowered conditions through the cooler 3. The bubbles of chlorine molecules continue to rise to the third group of light wave energy zones and continue the chlorination reaction. The hydrogen chloride gas generated by the chlorination reaction is separated from the liquid material by bubbling in the gas-liquid separation unit 5, and then enters the gas-liquid cyclone separator for gas-liquid separation. The liquid semi-finished product separated by the cyclone is refluxed into the chlorination reaction tower 1 through the reflux port 14, and the hydrogen chloride gas enters the tail gas treatment system 13 for absorption and treatment. The reactants generated by the reaction are discharged from the reactant outlet 10.

The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope.
