Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of halogenated hydrocarbon tail gas purification, and particularly relates to a halogenated hydrocarbon tail gas hypergravity adsorption composition and a tail gas treatment method and device thereof. BACKGROUND

[0002] Halogenated hydrocarbon VOCs are compounds in which one or more hydrogen atoms of VOCs are replaced by halogen atoms, which can be divided into saturated halogenated hydrocarbons, unsaturated halogenated hydrocarbons and aromatic halogenated hydrocarbons. Halogenated hydrocarbon acute poisoning can cause damage to multiple systems and multiple organs such as nervous system, heart, lung, liver and kidney, and even cause sudden death, which can cause serious health hazards. Halogenated hydrocarbon tail gas generally has low water solubility, poor biodegradability, and easy secondary pollution in the process of oxidation and incineration, and therefore the physical absorption method is currently the most suitable halogenated hydrocarbon tail gas treatment technology.

[0003] At present, there are many end treatment technologies for VOCs, such as absorption, low-temperature plasma, photocatalysis, biological purification, adsorption, catalytic oxidation, boiler thermal incineration, regenerative thermal oxidation (RTO) and the like. When halogenated hydrocarbons are subjected to conversion, due to their stable chemical properties, incomplete conversion occurs when the conversion method is used, and secondary pollutants are easily formed, and even pollutants such as dioxin and HCL are produced. These secondary pollutants have the characteristics of high toxicity, strong corrosion and easy mutation, and cause greater harm.

[0004] The conventional adsorption method of halogenated hydrocarbons generally uses activated carbon or activated carbon fiber as the adsorbent. The activated carbon has poor adsorption effect on halogenated hydrocarbons, poor desorption performance, and general solvent recovery quality, and the surface of the activated carbon has catalytic function, which easily leads to decomposition of a small amount of halogenated hydrocarbons to produce acidic substances. The activated carbon fiber has high adsorption capacity, but is easily oxidized to produce secondary pollutants. SUMMARY

[0005] To solve the above problems in the prior art, the present application provides a halogenated hydrocarbon tail gas hypergravity adsorption composition and a tail gas treatment method and device thereof, and develops a special adsorbent for halogenated hydrocarbons, which can realize recovery and reuse of chlorinated hydrocarbons by being used in cooperation with a hypergravity machine.

[0014] The second aspect of the present application is to provide a halocarbon tail gas hypergravity adsorption treatment method, comprising the following steps:

[0015] (1) continuously adding the said halocarbon tail gas hypergravity adsorption composition into a hypergravity rotating bed, forming a molecular level thickness film and microparticles on the surface of the filler in the hypergravity field;

[0016] (2) introducing the halocarbon-containing tail gas into the hypergravity rotating bed, the filler with the molecular level thickness film and microparticles on the surface contacting with the tail gas, capturing and adsorbing the organic volatile halocarbon in the tail gas.

[0017] Further, in the said halocarbon tail gas hypergravity adsorption treatment method, the gas-liquid ratio of the halocarbon-containing tail gas to the halocarbon tail gas hypergravity adsorption composition is 1:200-1:1500.

[0018] Further, in the said halocarbon tail gas hypergravity adsorption treatment method, the rotating speed of the hypergravity rotating bed is 300-1500r / min.

[0019] The third aspect of the present application is to provide a halocarbon tail gas hypergravity adsorption treatment device for the said method, comprising:

[0020] a hypergravity rotating bed, the gas inlet of the hypergravity rotating bed being connected to a halocarbon-containing tail gas source, for capturing and adsorbing the organic volatile halocarbon in the tail gas;

[0022] A receiving tank is connected to the discharge port of the high-gravity rotating bed and the water trap via a pipeline. The receiving tank is used to receive the liquid components separated by the high-gravity rotating bed and the liquid water captured by the water trap.

[0025] The present invention provides an adsorption composition that, in conjunction with a hypergravity machine, allows the adsorption composition to continuously collide and crush with the packing material under the influence of a hypergravity field, forming thin films and particles several molecular-level thick. This continuously renews the gas-liquid contact surface and allows direct contact with the volatile organic compounds in the exhaust gas, capturing and absorbing halogenated hydrocarbon molecules to achieve removal. This method can be used for the absorption and treatment of exhaust gases containing halogenated hydrocarbons in industries such as chemical and pharmaceutical manufacturing, and has a wide range of applications and good practical value.

[0030] like Figure 1 As shown, this embodiment of the invention provides a supergravity adsorption treatment device for halogenated hydrocarbon tail gas, which mainly includes a supergravity rotating bed 1, a water trap 2, a receiving tank 3, a water pump 4, and corresponding gas concentration sensors, flow sensors, and PLC controllers. The functional components are connected to each other through corresponding pipelines.

[0031] Specifically, the supergravity rotating bed 1 gas inlet is connected by pipeline to the halogenated hydrocarbon-containing tail gas source, and the packing of the supergravity rotating bed 1 is contacted with the tail gas by spraying the adsorption composition, to capture and adsorb the organic volatile halogenated hydrocarbons in the tail gas, so as to remove the halogenated hydrocarbons in the tail gas. After capture and adsorption, the tail gas is divided into two parts, one part of the heavy components containing halogenated hydrocarbons and other harmful substances accumulates in the bottom of the supergravity rotating bed 1 with the adsorption composition and is discharged, and the other part of the light component tail gas after removing the halogenated hydrocarbons is discharged from the exhaust port at the top of the supergravity rotating bed 1, realizing pollution-free emission.

[0032] To further improve the adsorption purification effect of the tail gas in the supergravity rotating bed 1 and meet the tail gas emission requirements, the device is also provided with a water trap 2 connected by pipeline to the exhaust port of the supergravity rotating bed 1, which is used to capture the water in the gaseous components separated by the supergravity rotating bed 1; the tail gas after removing the water is discharged from the exhaust pipeline at the top of the water trap 2 to the environment.

[0033] In addition, the adsorption composition (liquid component) containing halogenated hydrocarbons and other harmful substances separated by the supergravity rotating bed 1 is discharged from the supergravity rotating bed 1 to the receiving tank 3. The receiving tank 3 is connected by pipeline to the liquid discharge port of the supergravity rotating bed 1 and the water trap 2, and an electromagnetic valve 9 is arranged on the pipeline, which is used to receive the liquid component separated by the supergravity rotating bed 1 and receive the liquid water trapped by the water trap 2.

[0034] To fully remove the VOC in the liquid component separated by the supergravity rotating bed 1, the receiving tank 3 is connected by pipeline to the supergravity rotating bed 1 through a water pump 4, which is used to transport the liquid component received in the receiving tank 3 to the supergravity rotating bed 1 through the water pump 4 for further separation treatment, so as to remove the volatile substances contained in the liquid component in the receiving tank 3.

[0035] By fully removing the volatile gas substances in the liquid component, the purity of the liquid component in the receiving tank 3 is also indirectly improved, which is mainly high-purity halogenated hydrocarbon compounds, realizing the recovery and reuse of chlorinated hydrocarbons.

[0036] In order to realize real-time monitoring of the production process of the halogenated hydrocarbon-containing tail gas supergravity adsorption treatment device, corresponding gas concentration sensors, flow sensors and PLC controllers are provided to improve production efficiency and safety stability.

[0037] Specifically, the gas concentration sensors used include a first gas concentration sensor 5 and a second gas concentration sensor 6. The first gas concentration sensor 5 is installed on the pipeline at the air inlet of the high gravity rotating bed 1 and is used to monitor the concentration of halogenated hydrocarbons in the exhaust gas introduced into the high gravity rotating bed 1 in real time. The second gas concentration sensor 6 is installed on the pipeline at the exhaust outlet of the water trap 2 and is used to monitor the concentration of halogenated hydrocarbons in the exhaust gas discharged into the environment in real time. By monitoring the concentration changes at the air inlet and exhaust outlet, the ventilation rate of the exhaust gas or the rotation speed of the high gravity rotating bed 1 is adjusted in real time to ensure that the halogenated hydrocarbons in the exhaust gas are completely eliminated.

[0038] The flow sensors used include a first flow sensor 7 and a second flow sensor 8. The first flow sensor 7 is installed on the pipeline between the bottom drain port of the rotating bed 1 and the top inlet port of the receiving tank 3, and is used to monitor the flow rate of the liquid component discharged from the rotating bed 1 in real time. The amount of adsorption composition added is adjusted accordingly based on the flow rate. The second flow sensor 8 is installed on the reflux pipeline between the bottom drain port of the receiving tank 3 and the top inlet port of the rotating bed 1, and is used to monitor the flow rate of the liquid component during reflux and re-adsorption treatment in real time. After multiple reflux and re-adsorption treatments, the high-purity halogenated hydrocarbon heavy component is discharged from the bottom of the rotating bed 1 for recycling.

[0039] In addition, to improve the treatment efficiency of halogenated hydrocarbon tail gas, the halogenated hydrocarbon tail gas supergravity adsorption treatment device is also equipped with a PLC controller. The PLC controller is electrically connected to the supergravity rotating bed 1, the first gas concentration sensor 5 and the second gas concentration sensor 6, the first flow sensor 7 and the second flow sensor 8, and the solenoid valve 9. Based on the tail gas concentration monitored by the first gas concentration sensor 5 and the second gas concentration sensor 6, the first flow sensor 7 and the second flow sensor 8, and the flow rate of the liquid component, the PLC controller adjusts the amount of halogenated hydrocarbon tail gas introduced, the amount of adsorption composition added, and controls the rotation speed of the supergravity rotating bed 1 in real time, so as to achieve the recovery and reuse of heavy halogenated hydrocarbon components while removing halogenated hydrocarbons from the tail gas.

[0040] Based on such Figure 1 The invention also provides a special adsorption composition for halogenated hydrocarbons, which, when used in conjunction with the supergravity rotating bed 1, enables the recovery and reuse of halogenated hydrocarbons.

[0041] The halogenated hydrocarbon tail gas supergravity adsorption composition mainly comprises the following components in parts by weight: 10-20 parts of dispersant; 50-80 parts of encapsulating agent; 5-10 parts of stabilizer; 3-5 parts of solubilizer; and 50-100 parts of water.

[0042] As a preferred technical solution, the halogenated hydrocarbon tail gas supergravity adsorption composition mainly comprises the following components in parts by weight: 12-18 parts of dispersant; 55-75 parts of encapsulating agent; 6-8 parts of stabilizer; 3.5-4 parts of solubilizer; and 60-90 parts of water.

[0043] As a preferred technical solution, the supergravity adsorption composition for halogenated hydrocarbon tail gas mainly comprises the following components in parts by weight: 15-17 parts of dispersant; 65-70 parts of encapsulating agent; 7-8 parts of stabilizer; 3.8-4 parts of solubilizer; and 80-85 parts of water.

[0044] The dispersant used in this invention is selected from one or a combination of several of ethylene glycol, propylene glycol, methylpentanol, sodium dodecyl sulfate, cellulose derivatives, polyacrylamide, and fatty acid polyethylene glycol esters. Ethylene glycol is preferred, as the addition of the dispersant can effectively reduce the surface tension of the liquid-liquid phase, forming a stable microemulsion.

[0045] The encapsulating agent used in this invention is selected from one or a combination of several of α-cyclodextrin, β-cyclodextrin, and hydroxypropyl β-cyclodextrin. β-cyclodextrin is preferred. The encapsulating agent encapsulates macromolecular pollutants, such as chlorobenzene and p-dichlorobenzene, through hydrogen bonding, van der Waals forces, and steric effects. The absorption rate of benzene series halogenated hydrocarbon pollutants increases by 250 times in β-cyclodextrin aqueous solutions.

[0046] The stabilizer used in this invention is selected from one or a combination of sodium citrate, sodium gluconate, sodium phosphate, and sorbitol. Sodium citrate is preferred, as the addition of this stabilizer can maintain the stability of the composition system.

[0047] The solubilizer used in this invention is selected from one or a combination of sodium dioctyl succinate and sodium glycocholate. The addition of the solubilizer can increase the solubility of the haloalkanes and reduce their volatility. Common surfactants can be used as solubilizers, all of which have solubilizing effects.

[0048] Furthermore, the present invention also provides a method for treating halogenated hydrocarbon waste gas using the aforementioned halogenated hydrocarbon tail gas supergravity adsorption device and adsorption composition, such as... Figure 2 As shown, it mainly includes the following steps: (1) continuously adding the halogenated hydrocarbon tail gas hypergravity adsorption composition to a hypergravity rotating bed, forming a thin film and particles of molecular thickness on the surface of the packing in a hypergravity field; (2) introducing halogenated hydrocarbon tail gas into the hypergravity rotating bed, and the packing with a thin film and particles of molecular thickness on the surface contacting the tail gas to capture and adsorb the organic volatile halogenated hydrocarbons in the tail gas.

[0049] In this method for treating halogenated hydrocarbon tail gas using hypergravity adsorption, the gas-liquid ratio of the halogenated hydrocarbon tail gas to the hypergravity adsorption composition is 1:200-1:1500; preferably, the gas-liquid ratio is 1:500-1:1200; more preferably, the gas-liquid ratio is 1:750-1:950. The rotational speed of the hypergravity rotating bed is 300-1500 r / min; preferably, the rotational speed is 500-1300 r / min; more preferably, the rotational speed is 800-1000 r / min.
