Problems solved by technology

[0004] Applying immobilized carbonic anhydrase in the carbon dioxide absorption tower can speed up the absorption rate of carbon dioxide, but the immobilized enzyme is generally small in size, and the immobilized enzyme often flows away with the reaction solution during the reaction process, reducing its use efficiency
After the reaction is over, it is difficult to separate it from the packing of the absorption tower, which increases the cost of use

Embodiment 1

[0028] Inject 30.0L of 3M N-methyldiethanolamine solution into an 80.0L reactor storage tank, and spray it from the top into a 10.0L cylindrical stainless steel reactor at a rate of 10mL / min through a liquid circulation pump. The liquid flows back into the storage tank from the bottom of the kettle. The inner diameter of the stainless steel reactor is 10cm, and the height is 200cm. will contain 100% CO 2 The gas is passed into the bottom of the reaction kettle at a speed of 1.0mL / min, and reacts with N-methyldiethanolamine solution inside the reaction kettle for 1 hour, and 10mL of the reaction solution is taken from the bottom of the reaction kettle every 5min. The carbon dioxide absorption effect of the N-methyldiethanolamine solution was detected by measuring the pH value of the reaction solution. Two sets of experiments were carried out in parallel, and 5 layers of sieves filled with immobilized enzymes were evenly dispersed inside a group of reactors, and 10 g of immobi...

Embodiment 2

[0031] Inject 30.0L of 3M N-methyldiethanolamine solution into an 80.0L reactor storage tank, and spray it from the top into a 10.0L cylindrical stainless steel reactor at a rate of 10mL / min through a liquid circulation pump. The liquid flows back into the storage tank from the bottom of the kettle. The inner diameter of the stainless steel reaction kettle is 10cm, the height is 200cm, and the inner diameter of the kettle is filled with a porous inert filler with a diameter of 5mm. will contain 100% CO 2 The gas is passed into the bottom of the reaction kettle at a speed of 1.0mL / min, and reacts with N-methyldiethanolamine solution inside the reaction kettle for 1 hour, and 10mL of the reaction solution is taken from the bottom of the reaction kettle every 5min. The carbon dioxide absorption efficiency of the N-methyldiethanolamine solution is detected by the time required for the pH value of the reaction solution to change (from 9.3 to 8.0). After the reaction is over, the ...

Embodiment 3

[0034] Spray 1.0L of aqueous solution with 6.5g of zinc powder and 6.5g of titanium dioxide uniformly dispersed in it into a 2.0L cylindrical double-layer quartz reactor through a liquid circulation pump at a speed of 10mL / min. The inner diameter of the quartz reactor is 8cm , the height is 40cm. will contain 100% CO 2 The gas is passed into the bottom of the reaction kettle at a rate of 1.0mL / min. The temperature of the reactor was controlled at 0-5°C by jacket cooling water. Turn on a 1000W medium-pressure mercury lamp to illuminate it for photocatalytic reaction. After the reaction gas flow is stable, the gas is collected at the top of the reactor, and passed through 3M sodium hydroxide alkali solution and anhydrous calcium chloride drying tube in sequence to remove carbon dioxide and water vapor respectively, and the product is the synthesis gas product. Two sets of experiments were carried out in parallel. Three layers of immobilized enzyme screens were evenly placed i...

Abstract

The invention discloses an immobilized enzyme screen reactor and application thereof. The immobilized enzyme screen reactor at least comprises a screen structure unit, wherein the screen structure unit comprises a screen periphery fixed wall; the screen periphery fixed wall is internally provided with a screen; and the inner wall of the top end of the screen periphery fixed wall is provided with an inner screw thread, and the outer wall of the bottom end of the screen periphery fixed wall is provided with an outer screw thread. According to the immobilized enzyme screen reactor, a screen device positioned in an absorption tower and filled with immobilized enzymes is designed on the basis of the absorption tower, and the screen device is arranged between fillers inside the absorption tower; a dense mesh structure is favorable to the sufficient contact of the immobilized enzymes with reaction liquid and reaction gas and can realize the complete separation of the immobilized enzymes with the fillers and the reaction liquid, so that the effect of recycling is realized; and the double-layer screen is in a detachable structure and can be repeatedly filled with fresh immobilized enzymes, so that very good practicability is achieved.

Description

technical field [0001] The invention relates to the technical field of devices for immobilized enzymes, in particular to a screen reactor for immobilized enzymes and its application. Background technique [0002] In the process of human social and economic development, the burning of fossil fuels and biomass leads to the continuous accumulation of carbon dioxide in the atmosphere, resulting in a serious greenhouse effect. On the other hand, carbon dioxide is widely used in various fields such as food, industry, agriculture, medical treatment, national defense, and commerce, and has potential resources. Therefore, it is imminent to realize its resource utilization through carbon dioxide capture. At present, carbon dioxide capture is mainly recovered and reprocessed from industrial by-product gas, flue gas, kiln gas and waste gas. Carbon dioxide capture technology mainly includes solvent absorption method, pressure swing absorption method, membrane permeation separation metho...
