Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the field of waste energy recovery and carbon sequestration, and in particular to a low-temperature waste energy recovery and carbon sequestration device. BACKGROUND
[0002] The current global carbon dioxide emissions amount to 40 billion tons per year, most of which is emitted from chimneys, which poses a threat to human health, pollutes the air, and faces two major core problems of carbon dioxide greenhouse effect and a substantial reduction in the service life of condensate water in the chimney.
[0003] First, for the problem of carbon dioxide emissions, according to the statistics of the U.S. Environmental Protection Agency, the contribution of carbon dioxide to the power supply and heating industry is as high as nearly half. The emission of a large amount of carbon dioxide in the air causes the earth's surface to rise sharply, thereby causing serious extreme weather events, glacier melting, sea level rise, etc. These problems have brought great challenges to the global ecosystem and human society.
[0004] Nowadays, there are many methods to reduce or fix carbon dioxide, which aims to convert carbon dioxide in the atmosphere into solid or liquid, thereby reducing its emissions, such as chemical absorption method, biological absorption method, injection method and carbon capture and storage, etc. However, due to the environmental unfriendliness, low efficiency, high energy consumption and storage difficulty, etc., it is difficult to apply to the more difficult chimney, therefore, changing the inherent thinking, solving the problem of emitting a large amount of carbon dioxide gas with low cost and high added value is of great significance to energy saving and emission reduction.
[0005] Secondly, the widespread application of desulfurization and denitrification equipment (80% have been installed) causes a large amount of water vapor to condense into water droplets on the inner wall of the chimney, and the substantial reduction in the service life of condensate water is also a very important key problem. Since the water vapor condenses into condensate water in the chimney, it contains acidic substances and other corrosive components, which causes serious corrosion to the inner wall of the chimney, seriously damages the structural integrity of the chimney, substantially shortens its service life, and even may cause safety accidents.
[0006] The current means to solve the water vapor is to increase the temperature in the chimney to avoid the condensation of water vapor into water droplets. Moreover, the heating can cause serious waste of energy, therefore, there is an urgent need for a solution that can avoid the formation of condensate water on the inner wall of the chimney and avoid the waste of additional energy.
[0007] In summary, it is necessary and urgent to develop a complete system that can effectively recover and utilize low-quality energy, efficiently fix a large amount of carbon dioxide, and at the same time solve the corrosion of condensate water. SUMMARY
[0008] The embodiment of the present application provides a low-temperature waste energy recovery and carbon fixation device to solve the problem of low-quality waste energy recovery and low-cost carbon fixation in the prior art.
[0009] In order to solve the above technical problems, the application is implemented as follows:
[0010] The embodiment of the present application provides a low-temperature waste energy recovery and carbon fixation device for waste energy recovery and carbon fixation, which comprises at least an energy recovery module, a carbon fixation module and a control module; the energy recovery module is connected with the carbon fixation module.
[0011] The energy recovery module provides the carbon fixation module and the control module with the required electric energy for work.

[0019] The thermoelectric generation assembly realizes thermoelectric generation based on the thermoelectric effect, especially the Seebeck effect, and realizes the conversion of heat energy into electric energy through a thermocouple or a thermoelectric module. The thermoelectric generation assembly is based on low-temperature waste energy, generates a certain temperature difference through the low-temperature convection heat exchange between the low-quality waste heat contained in the chimney and the ambient air outside the chimney, and then continuously drives the thermoelectric generation assembly to generate power, which is not affected by day and night.
[0020] The temperature of the medium and low temperature residual energy is 120-150 ℃, the temperature of the ambient air is 25-30 ℃, and the temperature difference of the thermoelectric generator assembly is 100-120 ℃.
[0021] The wind power generation is realized by means of a fluidization assembly; the fluidization assembly realizes the conversion of high-speed flow in the chimney into electric energy based on electromagnetic induction and aerodynamic principles.
[0022] The working flow rate of the wind power generation is 2-10 m / s, the flue gas flow rate of the chimney is 8-15 m / s, and the chimney can work.
[0023] The fluidization assembly generates up-and-down reciprocating motion by fluidization effect, and condenses and captures water vapor into condensed water on the inner wall, providing a water source required for the operation of the carbon dioxide electrolytic cell assembly; a pressure relief port is arranged on the side wall of the fluidization assembly, and the fluidization assembly is driven by gas wind energy.
[0024] The fluidization effect and / or the fluidization energy is the energy contained by an object in a balanced state under the action of gravity and the buoyancy of gas, such as the kinetic energy of the object moving up and down during suspension.
[0025] The condensed water is formed by condensation of water vapor.
[0026] The fluidization assembly can also convert mechanical energy, convert the up-and-down reciprocating linear motion of the fluidization assembly into circular motion, provide the mechanical energy for the movement of the carrier, and the unit for converting the mechanical energy is a crank and connecting rod structure; at least two groups of the fluidization assemblies are used to alternately and reciprocally supplement the rotary motion, and then the stable output of the mechanical energy is realized through regulation and control, and the continuous mechanical energy is provided for the preparation of products.
[0027] The pressure power generation assembly cooperates with the fluidization assembly to generate periodic intermittent pressure, realizes the piezoelectric power generation process by positive pressure electric effect; the pressure power generation assembly generates electricity by extruding at least two pieces of piezoelectric ceramic through an impact block, and compared with a single piece, the amplification effect is several times, and the current is larger.
[0028] The periodic intermittent pressure is the force frequently extruded by the fluidization assembly.
[0029] The electric energy recovered by the thermoelectric generator assembly, the fluidization assembly and the pressure power generation assembly is stored in a storage battery, and then is used again.
[0030] The carbon dioxide collection and atomization dissolving device realizes the saturation of the carbon dioxide in the condensed water by gas-liquid separation mixing, and realizes high-ratio adsorption by atomization to increase the unit mass surface area of the droplets; in the carbon dioxide collection and atomization dissolving device, one way of the gas at least including the carbon dioxide in the chimney forms negative pressure through the Venturi tube, thereby driving the condensed water collected by the inner wall of the fluidization assembly to enter the closed container of the gas-liquid separation mixing together, and the gas pressure drives the condensed water to enter the liquid path of the atomization nozzle, and another way of the gas at least including the carbon dioxide enters the gas path of the atomization nozzle to mix with the liquid path of the atomization nozzle to realize the high-ratio dissolution and collection of the carbon dioxide.
[0031] The atomization nozzle is a two-phase flow atomization nozzle, and the gas path and the liquid path are used to perform the atomization process.
[0032] The negative pressure is formed due to the narrowing of the pipeline of the Venturi tube and the sudden increase of the gas flow rate, and the condensed condensed water on the inner wall of the fluidization assembly can be extracted from the side path of the Venturi tube without power consumption.
[0033] The carbon dioxide electrolysis cell device electrolyzes the captured carbon dioxide and water vapor into alcohol materials including methanol; the carbon dioxide electrolysis cell device adopts a low potential working technology, and in a solution containing a pyridine catalyst, the atomized two-phase flow of the dissolved carbon dioxide is continuously sent to the negative electrode of the carbon dioxide electrolysis cell device for electrolysis, the positive electrode generates oxygen discharge, the negative electrode generates alcohol, and the alcohol is collected.

[0035] The alcohol further includes ethylene glycol.
[0036] The pyridine catalyst does not have material loss and property change in the electrolysis process, and subsequent addition of the catalyst required for electrolysis is not required.
[0037] The carbon nanotube growth device uses the alcohol generated by the electrolysis as raw material, and grows into the solid carbon material on the carrier interface under the action of the electric energy. The solution of the carrier input into the carbon nanotube growth device is connected to the storage battery at both ends of the carrier, the Joule heat generated makes the alcohol decompose and continuously assemble into the solid carbon material on the surface of the carrier to obtain the product; the mechanical energy required by the movement and winding of the carrier is provided by the crank connecting rod.
[0038] The power of the electric energy is in the range of 20-40 W, which belongs to low power.
[0039] The Fe catalyst needs to be supplemented periodically, which belongs to consumables.

[0041] The device also comprises a reinforcement module for slowing down the corrosion of the chimney and facilitating the smooth emission of pollutants; the reinforcement module comprises a reinforced convection component and a turbulent flow consumption component.
[0042] The reinforced convection component generates high flow rate in the chimney based on the "chimney effect" to quickly discharge pollutants. At the same time, the reinforced convection component can generate a large temperature difference, so that the water vapor is quickly condensed and quickly discharged from the chimney, preventing corrosion, and the remaining water vapor in the flue gas is utilized by the carbon dioxide electrolytic cell component; in addition, through the high flow rate of the flue gas, high-frequency oscillation of the fluidization component and improvement of the power generation performance of the pressure power generation component can be realized.
[0043] The "chimney effect" is that the gas pressure is low at the middle and low positions of the chimney, and if the ambient air is connected in communication, the ambient air will be immediately sucked into the chimney due to the effect of density difference, and the mixed gas will quickly diffuse or be discharged from the chimney, so that it flows out of the outlet at a high flow rate.
[0044] The corrosion is due to the high water vapor content in the chimney and the electrochemical reaction formed by the dissolution of acidic gas in the condensed water in the flue gas.
[0045] The turbulent flow consumption component makes the gas experience a series of small-scale turbulent flow generation areas before the outlet of the chimney, so as to disperse and weaken the large turbulent flow, thereby reducing the overall turbulent flow intensity at the outlet and weakening the backflow inhibition of outflow, which helps to smoothly discharge the flue gas.
[0046] The large turbulent flow is formed by the high flow rate, and the large turbulent flow generates backflow at the outlet, thereby further inhibiting the normal flow rate at the outlet and inhibiting the normal emission of pollutants.
[0047] The control module is mainly used for coordinated control and optimization of the low-temperature waste energy recovery and carbon sequestration device. The circuit control component is used to generate, stabilize and collect current; the integrated control component uses a single-chip microcomputer to realize regulation and control of the carbon sequestration module and stable replenishment.
[0048] In the embodiment of the present application, the waste heat in the chimney, fluidization energy and wind energy are recovered by the thermoelectric generation assembly, the pressure generation assembly and the fluidization assembly, which can effectively convert the waste heat and energy into the electric energy independently, differentially and modularly; the wind energy in the chimney is converted into mechanical energy by the crank linkage; the carbon dioxide is collected by the carbon dioxide collection and atomization dissolving device, and the carbon dioxide is dissolved in the collected condensed water by the atomization technology; the alcohol and oxygen are prepared by the low potential electrolysis of the two-phase flow of the above-mentioned condensed water and carbon dioxide; the alcohol is further pyrolyzed at low power by the carbon nanotube growth device, and the solid carbon material is assembled on the carrier interface to finally prepare the product; the pyrolysis process utilizes differential energy to generate a larger temperature near the carrier; the recovered electric energy is more than the total energy of the electrolysis and the pyrolysis, and the entire device can work independently with self-production and self-sale; the entire device is modularly designed, which is convenient to install and replace the modules, and can assemble different modules according to the characteristics of the chimney and realize the functional customization of the product; the embodiment of the present application solves the problems of low-quality energy recovery and low-cost carbon sequestration in the prior art.
