[0063]In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the invention, the specific embodiments, structures, features and effects of the present invention are described in detail below in conjunction with the accompanying drawings and preferred embodiments.
[0064] The existing RTO regenerative combustion furnace is mainly composed of a furnace body, a ceramic regenerative body and a combustion system, and is a harmful gas treatment equipment.
[0065] like Figure 14 As shown, the interior of the furnace body is composed of three ceramic medium regenerators and a common combustion chamber, from right to left are the first, second and third regenerators.
[0066] When working, the combustion chamber and the three regenerators work cyclically and in coordination. In the first stage: the harmful gas is sent to the regenerative chamber 1 through the induced draft fan. The heat is released, and the harmful gas heats up and enters the combustion chamber. It is burned through the fire source ejected from port b. After combustion, it is discharged through the second combustion chamber. The induced draft fan is sent into the second regenerative chamber, the ceramic regenerator d releases heat, and the harmful gas heats up and enters the combustion chamber for combustion. After combustion, it is discharged through the third regenerative chamber. It is sent into the third chamber of regenerative by induced draft fan, the ceramic regenerator e releases heat, the harmful gas heats up and enters the combustion chamber for combustion, and after combustion, it is discharged through the first regenerative chamber, and the ceramic regenerator c in the first chamber heats up and stores heat; one, two, Three-stage cycle work.
[0067] During the working process of the above RTO regenerative combustion furnace, the flow direction of harmful gas is a, which enters the furnace body from bottom to top, is discharged from top to bottom, and burns at port b: 1. During the process of discharging harmful gas after burning, only Contact with the ceramic regenerator to make the ceramic regenerator heat up and store heat, and the heat storage efficiency of the ceramic regenerator is poor; 2. After the harmful gas is burned, according to the principle of thermal expansion, the carbon dioxide and water vapor produced by it have a high temperature and no external force. Therefore, in order to make it contact with the ceramic regenerator, measures such as fans must be installed to change its discharge direction, and increasing external force will increase energy consumption; 3. Harmful gases are burned in the combustion chamber, which The fire source is to enter the combustion chamber through the b port to burn the harmful gas. The flames are arranged in bundles. When burning, some harmful gases burn in direct contact with the flame, and some harmful gases burn in indirect contact with the flame, resulting in insufficient combustion of the harmful gas. In addition, the temperature of each part of the ignition source varies, which leads to insufficient combustion of harmful gases.
[0068] For this, as Figure 1-13 As shown, the present invention proposes to produce a volatile organic pollutant treatment device, which includes a frame body on which a combustion system 100, an air intake mechanism 200 and an exhaust mechanism 300 are installed, wherein the air intake mechanism 200 is used for pulling volatile organic pollutants. Organic pollutants, that is, harmful gases are fed into the combustion system 100 for combustion, and the feeding direction is from bottom to top. The products of the combustion of harmful gases, such as carbon dioxide, water vapor, etc., are discharged through the discharge mechanism 300, and the discharge direction is from the bottom. supremacy.
[0069] Compared with the prior art, in this solution: 1. The overall flow direction of the harmful gas is from bottom to top, the regenerator 630 in the combustion system 100 is located directly above the combustion chamber 620 where the harmful gas is burned, and the flame generated by the combustion Directly contact with the heat storage body 630, heat the heat storage body 630 to heat up, and the heat storage efficiency is higher; 2. The fire source unit 610 that burns the harmful gas, through various measures, the generated fire source is evenly distributed and the temperature is balanced , and then realize the full combustion of harmful gases, which will be explained one by one later; 3. During the emission of carbon dioxide and water vapor produced by the combustion of harmful gases, there is no need for any external force to interfere with their flow direction, and no additional energy consumption is required.
[0070] like Figure 3-4 As shown, the combustion system 100 includes a furnace body 500 mounted on a frame body. The furnace body 500 is provided with a combustion mechanism 600 , and a pipe network group 700 is provided between the upper and lower ends of the combustion mechanism 600 .
[0071] Among them, the combustion mechanism 600 is used to burn harmful gases, and the pipe network group 700 is used for the communication between the combustion mechanism 600 and the intake mechanism 200 and the combustion mechanism 600 and the exhaust mechanism 300 .
[0072] like Figure 9-13 As shown, the combustion mechanism 600 includes a fire source unit 610 and a heat storage unit, wherein the fire source unit 610 is used to provide a fire source for the combustion of harmful gases, and the heat storage unit is used to heat up and store heat. During the process of entering the ignition source unit 610, the harmful gas is heated up.
[0073] There are two groups of heat storage units located on the upper and lower sides of the fire source unit 610 respectively.
[0074] like Figure 10-13 As shown, the fire source unit 610 includes an installation chamber 611 whose upper and lower ends are open. The four sides of the installation chamber 611 are provided with fire source components, and the upper and lower ends of the installation chamber 611 are provided with combustion chambers 620 .
[0075] Specifically, as Figure 12 As shown, the fire source component includes a bracket 614 installed on the side of the installation chamber 611, a stove 615 is installed on the bracket 614, the output end of the stove head 615 extends into the installation chamber 611, and the stove head 615 in each group of fire source components is along the installation chamber The side length direction array of 611 is provided with multiple groups.
[0076] The stove heads 615 in the four groups of fire source components are communicated with each other through the gas supply pipe 616, and the gas supply pipe 616 is also communicated with the combustion source supply equipment. At this time, the ignition source is ignited by the igniter 613 arranged in the installation chamber 611.
[0077] Preferred embodiments such as Figure 13 As shown in the figure, among the four groups of fire source components, the two groups of fire source components whose sides of the installation chamber 611 are parallel to each other are located at the same height, and the two groups of fire source components where the sides of the installation chamber 611 are perpendicular to each other have a height difference, which means that , compared with the prior art, the flames are concentrated in a bundle shape, some harmful gases burn in direct contact with the flame, and some harmful gases burn in indirect contact with the flame, resulting in insufficient combustion. The four sets of fire source components cooperate with each other to form a A fire source network arranged in a crisscross pattern, when the harmful gas passes through the fire source network, the contact with the flame is more uniform and sufficient, so that all harmful gases can be in direct contact with the flame, thereby making the combustion of the harmful gas more sufficient.
[0078] Preferred embodiments such as Figure 11 As shown in the figure, a metal mesh plate 612 is arranged horizontally in the installation chamber 611, and the metal mesh plate 612 is provided with two groups and is located on the upper and lower sides of the fire source component. The surface temperature rises rapidly and the temperature of each part remains the same, which further keeps the temperature in the installation chamber 611 balanced. That is to say, when the harmful gas is in the installation chamber 611, the temperature of the fire source it is subjected to is the same, and the harmful gas is strengthened on the side. combustion sufficiency.
[0079] like Figure 9-10 As shown, the heat storage unit includes a heat storage body 630 disposed at the open end of the combustion chamber 620 and a communication chamber 640 disposed at the end of the heat storage body 630 .
[0080] Preferred embodiments such as Figure 10 As shown, a plurality of groups of heat storage holes 631 are evenly arranged in the heat storage body 630, the heat storage holes 631 are wavy in the vertical direction, and the heat storage holes 631 in the two groups of heat storage units are arranged in a staggered manner; the meanings are: 1. In the prior art, the heat storage holes are generally in the shape of straight holes arranged vertically. When the gas passes through the heat storage holes, part of the gas is in direct contact with the hole wall, and part is not in contact with the hole wall, resulting in the contact between the gas and the heat storage hole. Insufficient and low heat exchange efficiency, in this solution, when the gas passes through the wavy heat storage hole, it will collide with the hole wall of the heat storage hole and be scattered, so that the gas can fully contact the wall of the heat storage hole , the heat exchange efficiency is high; 2. The heat storage holes 631 in the upper and lower groups of heat storage units are arranged in a staggered manner. During the process of gas rising in the vertical direction, the gas is further divided and dispersed, and the gas and the heat storage holes are further improved. sufficient contact with the wall.
[0081] The working process of the combustion mechanism 600 is embodied as follows:
[0082] In the initial state, the lower heat storage unit is heat storage unit a, the upper heat storage unit is heat storage unit b, the lower combustion chamber is combustion chamber a, and the upper combustion chamber is combustion chamber b.
[0083] First, the air intake mechanism 200 pulls the harmful gas into the installation chamber 611 through the communication chamber 640, the heat storage body 630 and the combustion chamber a in the heat storage unit a. During this process, the heat storage body 630 releases heat to heat the harmful gas;
[0084] After the harmful gas is heated and ignited by the fire source network provided by the fire source component in the installation chamber 611, it is fully burned in the combustion chamber b, and the flame generated by the combustion directly heats the heat storage body 630 in the heat storage unit b for heat storage. Better thermal efficiency;
[0085] After the harmful gas is burned, it is discharged to the outside through the heat storage body 630, the communication chamber 640 and the discharge mechanism 300 in the heat storage unit b;
[0086] After a preset time, the driving source 800 drives the combustion mechanism 600 to rotate 180 degrees, so that the heat storage unit a and the heat storage unit b are exchanged, and the above-mentioned combustion process is continued.
[0087] like Figure 4-6 As shown, the pipe network group 700 includes a casing 703 horizontally installed on the frame body. One end of the casing 703 is closed and one end is open, and the two groups of heat storage units are symmetrically arranged with respect to the axis of the casing 703 .
[0088] The inner core body 706 is rotatably arranged in the casing 703, the end of the inner core body 706 is coaxially extended with a driving sleeve 707, the open end of the casing 703 is matched with a casing cover 705, and the casing cover 705 is provided with a drive sleeve for avoiding 707's avoidance hole.
[0089] The closed end of the casing 703 is provided with a connecting hole 704 , and the connecting holes 704 are arranged in two groups in an array along the circumferential direction of the casing 703 : a connecting hole a and a connecting hole b.
[0090] The end surface of the inner core body 706 is provided with air holes 708. The air holes 708 are arranged in two groups along the circumferential direction of the inner core body 706: air holes a and air holes b. b is connected.
[0091] The air hole a communicates with the communication chamber 640 in the thermal storage unit a through a connecting pipe a702, and the air hole b communicates with the communication chamber 640 in the thermal storage unit b through a connecting pipe b701.
[0092] like Figure 7 As shown, the driving source 800 is installed on the frame body, which is used to drive the inner core body 706 to rotate, and then drive the two groups of heat storage units to rotate 180 degrees and exchange positions.
[0093] Specifically, the drive source 800 includes a motor 801 installed on the frame body, and the motor 801 and the drive sleeve 707 are powered by a power transmission member, which is composed of a power transmission member a802, an intermittent member 803 and a power transmission member b804. The existing common power transmission route structure of the composition can be realized, and it will not be repeated. In addition, the reason why the intermittent component 803 is set is that when the motor 801 is continuously running, the driving sleeve 707 is driven to rotate periodically by the power transmission component, and the driving sleeve 707 is rotated every time. The second rotation of 180 degrees, the rotation of the drive sleeve 707 by 180 degrees means that the two sets of heat storage units rotate 180 degrees, and the positions are exchanged. Compared with the intermittent operation, the continuous operation of the motor 801 can start and stop when it is not needed, and the wear and tear is relatively small. Lighter, lower energy consumption and longer service life.
[0094] like Figure 1-2 As shown, the air intake mechanism 200 includes an induced draft fan 201 disposed on the frame body and an air intake pipe disposed between the induced draft fan 201 and the connecting hole a.
[0095] The discharge mechanism 300 includes a discharge pipe communicating with the connection hole b.
[0096] In a preferred embodiment, a turbocharger 400 is disposed between the intake mechanism 200 and the exhaust mechanism 300 .
[0097] There are two groups of intake pipes: intake pipe a202 and intake pipe b203, intake pipe a202 is provided between induced draft fan 201 and turbocharger 400, intake pipe b203 is provided between turbocharger 400 and connecting hole a.
[0098] There are two groups of discharge pipes: a discharge pipe a301 and a discharge pipe b302, the discharge pipe a301 is arranged between the turbocharger 400 and the connection hole b, and the discharge pipe b302 communicates with the turbocharger 400.
[0099] The significance of this is that in the process of the harmful gas being discharged through the exhaust pipe after being burned, the turbocharger 400 uses the kinetic energy generated by the gas discharge to assist the harmful gas into the intake pipe, and the turbocharger 400 is the current There are turbocharged technical means to achieve it, so I won't go into details.
[0100] In addition, the setting of the turbocharger 400 assists the intake of harmful gases, so after the induced draft fan 201 is started for a period of time, the operating power of the induced draft fan 201 can be reduced, and the induced draft fan 201 can be reduced without affecting the intake of harmful gases. energy consumption.
[0101] like Figure 3-5 As shown, the furnace body 500 is provided with an installation hole, the drive sleeve 707 is installed in the installation hole through a bearing, and the connecting pipe b701 and the connecting pipe a702 are both hard pipe structures, so as to realize the installation of the combustion mechanism 600 in the furnace body 500 , of course, other installation methods that can achieve the purpose of this solution are also possible, which will not be described in detail.
[0102] The working principle of the present invention:
[0103] Step 1: The induced draft fan 201 operates to draw the harmful gas into the installation chamber 611 through the air inlet pipe, the connecting hole a, the air hole a, the connecting pipe a702, the communication chamber 640 in the thermal storage unit a, the thermal storage body 630, and the combustion chamber a in sequence, During this process, the heat storage body 630 in the heat storage unit a releases heat to heat up the harmful gas;
[0104] Step 2: After the harmful gas is heated and ignited by the fire source network provided by the fire source component in the installation chamber 611, it is fully burned in the combustion chamber b, and the flame generated by the combustion directly heats the heat storage body 630 in the heat storage unit b. heat, better heat storage efficiency;
[0105] Step 3: Substances generated after the combustion of the harmful gas, such as carbon dioxide, water vapor, etc., are sequentially discharged to the outside through the regenerator 630 and the communication chamber 640, the connecting pipe b701, the air hole b, the connecting hole b, and the discharge pipe in the thermal storage unit b;
[0106] Step 4: After the preset time, the drive source 800 operates to drive the drive sleeve 707 to rotate 180 degrees, and the drive sleeve 707 rotates to drive the inner core body 706 to rotate synchronously, so that the air hole a is communicated with the connection hole b, and the air hole b is communicated with the connection hole a;
[0107] At the same time, the rotation of the drive sleeve 707 also pulls the connecting pipe b701, the connecting pipe a702 and the two sets of heat storage units to rotate 180 degrees, and the two sets of heat storage units exchange positions;
[0108] Step 5: The harmful gas enters the installation chamber 611 through the air inlet pipe, the connecting hole a, the air hole b, the connecting pipe b701, the communication chamber 640 in the thermal storage unit b, the thermal storage body 630, and the combustion chamber b in sequence. The heat storage body 630 in the heat unit b releases heat to heat up the harmful gas;
[0109] Step 6: After the harmful gas is heated and ignited by the fire source network provided by the fire source component in the installation chamber 611, it is fully burned in the combustion chamber a, and the flame generated by the combustion directly heats the heat storage body 630 in the heat storage unit a. heat, better heat storage efficiency;
[0110] Step 7: Substances generated after the combustion of the harmful gas, such as carbon dioxide, water vapor, etc., are sequentially discharged to the outside through the regenerator 630 and the communication chamber 640, the connecting pipe a702, the air hole a, the connecting hole b, and the discharge pipe in the thermal storage unit a;
[0111] Step 8: After the preset time, the driving source 800 drives the driving sleeve 707 to rotate 180 degrees again, so that the air hole a is communicated with the connecting hole a, the air hole b is communicated with the connecting hole b, the connecting pipe b701, the connecting pipe a702 and the two sets of heat storage The unit turns 180 degrees again.
[0112] This cycle repeats.
[0113] Preferred embodiments such as figure 2 and 5 As shown, in the above steps 4 and 8, the driving source 800 drives the driving sleeve 707 and the inner core 706 to rotate, and in the process of changing the communication relationship between the air holes a, b and the connecting holes a, b, the air holes and the connecting holes There is a period of time when they are not connected to each other. Although the time is very short, the ingress and egress of harmful gases continue during this time. Can not be realized, there are: 1. During this period of time, the substances produced by the combustion of harmful gases, especially carbon dioxide, cannot be discharged in time, resulting in an increase in the concentration of carbon dioxide in the combustion chamber 620, which will affect the combustion in the combustion chamber 620; 2. During this period of time, the gas pressure in the intake pipe and the connecting pipes a and b increases. After this period of time, the air hole and the connecting hole are restored, and the pressure in the intake pipe and the connecting pipes a and b is reduced and restored. Repeatedly, the anti-fatigue strength requirements of the intake pipe and the connecting pipes a and b are relatively high; in order to solve the above problems, the pressure-stabilizing valve 900 is provided on the intake pipe, the connecting pipe a702 and the connecting pipe b701.
[0114] Specifically, as Figure 8 As shown, the regulator valve 900 includes a valve housing 901, the open end of the valve housing 901 is provided with a valve cover 902, and the closed end is provided with a nozzle 903, which is connected to the intake pipe or the connecting pipe a702 or the connecting pipe b701.
[0115] A piston 904 is slidably arranged in the valve housing 901 , and a spring 905 between the piston 904 and the valve cover 902 is also arranged in the valve housing 901 .
[0116] In the above steps 4 and 7, during the time period when the air hole and the connecting hole are not connected to each other, the substances produced by the combustion of the harmful gas enter the valve housing 901 through the nozzle 903 for temporary storage, the piston 904 retreats, and the spring 905 is compressed. When the air hole and the connection hole are restored, the spring 905 releases the elastic force, so that the substance in the valve shell 901 returns to the connecting pipe a702 or the connecting pipe b701, and is discharged to the outside world. Similarly, in the above steps 4 and 7, the harmful gas It can be temporarily stored in the valve housing 901 , and then pushed back into the intake pipe, and finally sent to the combustion mechanism 600 .
