Description

Technical Field

[0002] In the field of industrial combustion, traditional combustion devices usually use a high-oxygen environment for combustion. Although they can achieve high combustion efficiency, they are prone to produce a large amount of harmful emissions such as nitrogen oxides, causing serious pollution to the environment. Although existing combustion devices can reduce harmful emissions, in actual applications, there is still insufficient mixing uniformity between fuel and gas, which easily leads to incomplete combustion. In addition, the flow control accuracy of gas and fuel during the combustion process is limited, making it difficult to achieve a stable ultra-low oxygen environment. In addition, after the equipment has been running for a long time, residues are easily attached to the inner wall of the combustion pipe, affecting the atomization effect, increasing maintenance costs and downtime.

[0030] The first transposition motor 135 is activated to rotate the first feed circular plate 107. Under the action of the long liquid storage tube 106, the long liquid storage tube 106, the first feed circular plate 107, and the second feed circular plate 121 all rotate synchronously, thus switching the positions of the two long liquid storage tubes 106.

Under the action of the long air storage tube 105, the long air storage tube 105, the first air intake circular plate 108, and the second air intake circular plate 120 all rotate synchronously, thus switching the positions of the two long air storage tubes 105.

[0031] The air intake assembly and the feed assembly are both connected to the auxiliary assembly. The support plate 2 103 is fixedly installed with a liquid replenishing tube 117, an air replenishing tube 119, and a feed tube 128. The sealing ring plate 1 115 is also rotatably installed with a sealing ring plate 2 116. The sealing ring plate 2 116 is fixedly connected to the square frame 101. The axes of the sealing ring plate 1 115, the sealing ring plate 2 116, and the auxiliary circular plate 2 129 are on the same straight line. When the auxiliary circular plate 2 129 rotates relative to the support plate 2 103, the sealing ring plate 115 rotates relative to the sealing ring plate 2 116.

[0032] A guide tube 114 is fixedly provided between the long mixing tube 110 and the sealing ring plate 115. The guide tube 114 is connected to the interior of the corresponding long mixing tube 110. The end of the feeding tube 128 farthest from the support plate 103 is fixedly connected to the sealing ring plate 116. Feed holes 118 are symmetrically provided on the feeding circular plate 107. The feed holes 118 are respectively connected to the corresponding long liquid storage tubes 106. When the feed hole 118, the feeding tube 128 and the guide tube 114 are connected, a liquid feeding pipeline is formed. When the feed hole 118 and the liquid replenishing tube 117 are connected, a liquid replenishing pipeline is formed.

[0033] Start the auxiliary motor 134 to drive the auxiliary circular plate 2 129 to rotate, and the two long mixing tubes 110 rotate synchronously, so that the guide tube 114 and the feeding tube 128 corresponding to the long mixing tube 110 can be connected respectively. Start the transposition motor 135 to drive the feeding circular plate 107 to rotate, and the two long liquid storage tubes 106 rotate synchronously, so that the feeding hole 118 can be connected with the liquid replenishing tube 117 and the feeding tube 128 respectively. When the liquid replenishing tube 117 and the feeding hole 118 are connected, the feed push rod 127 and the other feeding hole 118 are in a connected state.

[0034] Air intake holes 109 are symmetrically provided on the air intake circular plate 108, and connecting holes 113 are symmetrically provided on the connecting circular plate 111. The combustion cone 104 is connected to the connecting hole 113 closest to the axis of the air intake circular plate 108. The air intake holes 109 are respectively connected to the corresponding air storage long tubes 105. When the air intake holes 109 and the air supply pipe 119 are connected, an air supply pipe is formed. When the air intake holes 109, the mixing long tube 110, and the connecting holes 113 are connected, an air intake pipe is formed. At this time, a Venturi tube is formed between the air storage long tube 105, the mixing long tube 110, and the combustion cone 104, and an atomization pipe is formed between the air storage long tube 105, the liquid storage long tube 106, and the mixing long tube 110.

[0035] Start the auxiliary motor 134 to drive the auxiliary circular plate 2 129 to rotate, and the two long mixing tubes 110 rotate synchronously, so that the long mixing tube 110 and the connecting hole 113 can be connected respectively, thereby realizing the replacement of the long mixing tube 110, and start the transposition motor 2 136 to drive the air intake circular plate 1 108 to rotate, and the two long air storage tubes 105 rotate synchronously, so that the air intake hole 109 can be connected with the long mixing tube 110 and the air supply tube 119 respectively. When the air intake hole 109 and the long mixing tube 110 are connected, the air supply tube 119 and the other air intake hole 109 are in a connected state.

[0036] When the two ends of the long mixing tube 110 are respectively connected to the air inlet hole 109 and the connecting hole 113, the axis of the long gas storage tube 105 connected to the long mixing tube 110, the axis of the long mixing tube 110, and the axis of the combustion cone 104 are all on the same straight line. At this time, a Venturi tube is formed between the long gas storage tube 105, the long mixing tube 110, and the combustion cone 104.

[0037] The gas enters the mixing tube 110 along the air inlet hole 109 from the gas storage tube 105 connected to the mixing tube 110. Under the action of the gas entering the mixing tube 110, the fuel enters the mixing tube 110 from the liquid storage tube 106 corresponding to the mixing tube 110 along the feeding tube 128 and the guide tube 114. After entering the mixing tube 110, the gas and fuel are atomized through the connecting hole 113 and then burned in the cone 104.

[0038] Gas is injected into the other long gas storage tube 105 through the air supply pipe 119, and fuel is injected into the other long liquid storage tube 106 through the liquid supply pipe 117. After the gas in the long gas storage tube 105 is completely discharged, the transposition motor 2 136 is started to drive the air intake circular plate 108 to rotate, thereby realizing the switching of the long gas storage tube 105. After the fuel in the long liquid storage tube 106 is completely discharged, the transposition motor 135 is started to drive the feed circular plate 107 to rotate, thereby realizing the switching of the long liquid storage tube 106.

[0039] A cleaning slide 131 is slidably installed on the support plate 103, and a cleaning push rod 130 is fixedly provided on the cleaning slide 131. The inner diameter of the mixing long tube 110 is equal to the diameter of the cleaning push rod 130. The cleaning push rod 130 is used to clean the inside of the mixing long tube 110. A cleaning screw 132 is rotatably installed on the support plate 103. The cleaning screw 132 and the cleaning slide 131 form a spiral pair. A cleaning motor 133 is fixedly installed on the support plate 103, and the output shaft of the cleaning motor 133 is fixedly connected to the cleaning screw 132.

[0040] When it is necessary to clean the inside of the mixing tube 110, the cleaning motor 133 is started to drive the cleaning screw 132 to rotate, so that the cleaning slide 131 moves to the position farthest from the cleaning motor 133. At this time, the cleaning push rod 130 moves to the position farthest from the mixing tube 110, and then the auxiliary motor 134 is started to drive the auxiliary circular plate 2 129 to rotate, so that the positions of the two mixing tubes 110 are switched. At this time, the other mixing tube 110 is engaged with the guide tube 114 and the air storage tube 105 to continue working. The axes of the switching mixing tube 110 and the cleaning push rod 130 are on the same straight line. Online, then start the cleaning motor 133 to make the cleaning slide 131 move toward the direction close to the cleaning motor 133, so that the cleaning push rod 130 and the inner side of the mixing long tube 110 are engaged, and under the action of the cleaning push rod 130, the attachments on the inner wall of the mixing long tube 110 are cleaned, and finally the end of the cleaning push rod 130 is moved to the outside of the mixing long tube 110, that is, the cleaning of the mixing long tube 110 is completed. When there is no need to switch the mixing long tube 110, the cleaning push rod 130 is always in an engaged state with the mixing long tube 110, thereby preventing external impurities from entering the mixing long tube 110.

[0041] The square frame 101 is also symmetrically provided with a feed assembly, each of which includes two circular push blocks 123, which are respectively slidably matched with the corresponding gas storage long tube 105 and the liquid storage long tube 106, and the circular push blocks 123 are respectively used to push the gas in the gas storage long tube 105 and the liquid in the liquid storage long tube 106 to move. The feed assembly also includes a feed slide 126 slidably mounted on the square frame 101, and two feed screws 122 are rotatably mounted on the support plate 102. The feed screws 122 respectively form a spiral pair with the corresponding feed slides 126, and the support plate 102 is also fixed. Two feed motors 125 are fixedly installed, and the output shaft of the feed motor 125 is fixedly connected to the corresponding feed screw 122. A feed push rod 127 is fixedly provided on the feed slide 126. A circular electromagnet 124 is fixedly provided at the end of the feed push rod 127 farthest from the feed slide 126. The diameter of the circular electromagnet 124 is smaller than the diameter of the circular push block 123. The circular electromagnet 124 is used to push the corresponding circular push block 123 to move. Auxiliary motors 134 are also symmetrically provided on the support plate 102. The auxiliary motors 134 are respectively used to release pressure on the movement of the circular push block 123.

[0042] Start the feed motor 125 corresponding to the long gas tube 105 to drive the feed screw 122 to rotate, so that the corresponding feed slide 126 moves toward the direction close to the long gas tube 105, and the corresponding circular electromagnet 124 and feed push rod 127 move synchronously. The circular electromagnet 124 adsorbs and fixes the circular push block 123, and the circular push block 123 corresponding to the long gas tube 105 docked with the long mixing tube 110 moves toward the direction close to the combustion cone 104 under the action of the circular electromagnet 124. The gas in the long gas tube 105 moves into the long mixing tube 110 under the action of the circular push block 123. By controlling the speed at which the circular electromagnet 124 pushes the circular push block 123 to move, the gas is controlled. At the initial velocity of movement in the mixing tube 110, the fuel in the corresponding liquid storage tube 106 enters the mixing tube 110 under the action of the gas in the mixing tube 110, so that the support plate 2 103 in the liquid storage tube 106 moves toward the direction close to the combustion cone 104, and the feed motor 125 corresponding to the liquid storage tube 106 is started to make the corresponding circular electromagnet 124 move toward the direction close to the combustion cone 104. By controlling the moving speed of the circular electromagnet 124, the circular push block 123 always maintains the set speed to move, thereby preventing the amount of fuel entering the mixing tube 110 from being too much or too little, that is, ensuring that the ratio of fuel and gas entering the mixing tube 110 is always constant.

[0043] When the liquid replenishing pipe 117 replenishes fuel in the long liquid storage pipe 106 and the gas replenishing pipe 119 replenishes gas in the long gas storage pipe 105, the circular push block 123 in the long gas storage pipe 105 and the long liquid storage pipe 106 moves in the direction away from the combustion cone 104, and the circular push block 123 and the long gas storage pipe 105 and the gas in the circular push block 123 and the long liquid storage pipe 106 are discharged from the auxiliary motor 134. When the long gas storage pipe 105 and the long liquid storage pipe 106 are switched, the circular electromagnet 124 is turned off to release the adsorption of the circular push block 123, so that the long gas storage pipe 105 and the long liquid storage pipe 106 can be switched.

[0044] Flow sensors are provided in the long gas storage tube 105 , the long liquid storage tube 106 , and the long mixing tube 110 , and an igniter is also fixedly provided on the inside of the combustion cone 104 .

[0045] Working principle: Start the feed motor 125 corresponding to the long gas storage tube 105, so that the gas enters the long mixing tube 110 connected to the combustion cone 104, and start the feed slide 126 corresponding to the long liquid storage tube 106, so that the fuel enters the long mixing tube 110 connected to the combustion cone 104. The fuel and gas entering the long mixing tube 110 are atomized when entering the combustion cone 104, and are ignited by the igniter in the combustion cone 104, so that the atomized fuel is burned in the combustion cone 104, and the gas entering the long gas storage tube 105 is supplemented with a low oxygen content, thereby realizing low-oxygen combustion.

[0046] After the raw materials in the long gas storage tube 105 or the long liquid storage tube 106 are consumed, they are replaced by switching the long gas storage tube 105 or the long liquid storage tube 106, and the interior of the corresponding long mixing tube 110 is cleaned regularly by cleaning the push rod 130 to ensure the circulation effect of the long mixing tube 110.
