Description

Technical Field

[0002] Catalytic combustion is a purification method that uses a catalyst to oxidize and decompose combustible substances in exhaust gas at a relatively low temperature. Therefore, catalytic combustion is also called catalytic chemical conversion. Since the catalyst accelerates the process of oxidation and decomposition, most hydrocarbons can be completely oxidized by the catalyst at a temperature of 300-450°C.

[0003] However, when an existing high-efficiency catalytic combustion device is used, a blower is usually used for ventilation to achieve full combustion. When the catalytic gas is introduced, the temperature is too low, which affects the combustion temperature in the combustion chamber and thus affects the combustion process efficiency.

[0004] According to a Chinese patent application number 202022118485.8, a high-efficiency catalytic combustion device exchanges heat with the hot exhaust gas discharged from the chimney through a spirally rotating air intake pipe during use. However, the heat exchange area of ​​only one spirally rotating air intake pipe is limited and the heat exchange efficiency is low. Therefore, an improved high-efficiency combustion device is needed to address this problem. Utility Model Content

[0020] See also Figure 1-3The utility model provides a technical solution: a high-efficiency combustion equipment, including a combustion furnace 1, a smoke exhaust pipe 2 is fixedly arranged on the upper end of the combustion furnace 1, and a heat exchange mechanism for heat exchange is arranged inside the smoke exhaust pipe 2, and the heat exchange mechanism includes a first connecting pipe 3, a second connecting pipe 4, a fixing plate 5, and a diverter pipe 6. A first connecting pipe 4 is fixedly arranged on one side of the upper end of the smoke exhaust pipe 2, a second connecting pipe 4 is arranged on the outer surface of the lower end of the smoke exhaust pipe 2, a plurality of the second connecting pipes 4 are arranged, and are evenly spaced and distributed on the outer surface of the lower end of the smoke exhaust pipe 2, a fixing plate 5 is fixedly arranged inside the smoke exhaust pipe 2, and diverter pipes 6 are fixedly arranged between the fixing plates 5, and a plurality of the diverter pipes 6 are arranged, and are evenly spaced and distributed between the fixing plates 5.

[0021] The first connecting pipe 3 is connected to the second connecting pipe 4 and the inside of the smoke exhaust pipe 2. The exhaust gas that needs to be burned can be injected into the smoke exhaust pipe 2 through the first connecting pipe 3, and this part of the exhaust gas will be in the space between the two fixed plates 5 inside the smoke exhaust pipe 2, and the treated exhaust gas will enter the diverter pipe 6 in the smoke exhaust pipe 2, so that the treated hot exhaust gas and the first connecting pipe 3 can be injected into the exhaust gas that needs to be treated through the diverter pipe 6 for heat exchange. During the heat exchange, the diversion of the diverter pipe 6 can make the treated hot exhaust gas and the exhaust gas to be burned have a full and large area of ​​contact, and the heat exchange effect is better. The exhaust gas after heat exchange can be discharged from the second connecting pipe 4; then it enters the combustion chamber 8 formed by the partition 7 in the combustion furnace 1 from the second connecting pipe 4 for combustion treatment. At this time, this part of the exhaust gas has a very high temperature due to the heat exchange, so the subsequent exhaust gas combustion treatment efficiency can be improved.

[0022] A plurality of partitions 7 are evenly and fixedly arranged around the exhaust pipe 2 inside the combustion furnace 1, and a combustion chamber 8 is arranged between the partitions 7. The interiors of the plurality of second connecting pipes 4 are respectively communicated with the interiors of the combustion chambers 8, and the exhaust gas to be burned can be introduced into the combustion chamber 8 for combustion through the second connecting pipes 4; and the device is provided with partitions 7 to divide the plurality of combustion chambers 8, and the plurality of second connecting pipes 4 can divert the exhaust gas to be burned, so that part of the exhaust gas enters each combustion chamber 8, and then a catalyst is separately placed in each combustion chamber 8, so that part of the exhaust gas can be mixed with the catalyst; so as to improve the mixing effect of the exhaust gas to be burned and the catalyst, and further facilitate the subsequent exhaust gas combustion treatment;

[0023] A through groove 9 is provided between the lower end of the smoke exhaust pipe 2 and the combustion chamber 8, and each combustion chamber 8 can be mutually connected with the inside of the smoke exhaust pipe 2 through the through groove 9. After the exhaust gas to be burned enters the combustion chamber 8 from the second connecting pipe 4, it enters from the upper end of the combustion chamber 8, and then passes through the entire combustion chamber 8 from top to bottom for combustion and catalytic treatment. The treated exhaust gas can enter the smoke exhaust pipe 2 through the through groove 9, and then the treated exhaust gas enters the diversion pipe 6 from the smoke exhaust pipe 2 to perform heat exchange operation with the exhaust gas to be subsequently treated;

[0024] The exhaust pipe 2 is provided with a baffle plate 10 between the fixed plates 5. The baffle plate 10 can be used to baffle the exhaust gas to be burned that is introduced into the exhaust pipe 2 through the first connecting pipe 3, so that this part of the exhaust gas can flow in an S-shaped curve in the exhaust pipe 2, so that it can fully exchange heat with the hot exhaust gas in the multiple branch pipes 6; thereby further improving the heat exchange effect;

[0025] A fixing frame 11 is fixedly disposed at the lower end of the combustion furnace 1 , and the fixing frame 11 can improve the overall stability of the combustion furnace 1 .

Then, the exhaust gas to be burned that is passed into the exhaust pipe 2 by the first connecting pipe 3 can be deflected through the baffle plate 10, so that this part of the exhaust gas can flow in the exhaust pipe 2 in an S-shaped curve. At this time, the exhaust gas that has been burned in the combustion chamber 8 will be discharged upward from the exhaust pipe 2 and will enter the diversion pipe 6. At this time, the treated exhaust gas can be discharged through the diversion pipe 6. The hot exhaust gas is heat exchanged with the exhaust gas to be treated that has just been injected into the first connecting pipe 3. During the heat exchange, the treated hot exhaust gas can be fully contacted with the exhaust gas to be burned and treated over a large area due to the diversion of the diverter pipe 6, so the heat exchange effect is better. The exhaust gas after heat exchange can be discharged from the multiple second connecting pipes 4; then it enters the combustion chamber 8 formed by the partition 7 in the combustion furnace 1 from the second connecting pipes 4 for combustion treatment. At this time, the temperature of this part of the exhaust gas is very high due to the heat exchange, so the subsequent exhaust gas combustion treatment efficiency can be improved.

[0027] When the exhaust gas that has undergone heat exchange enters the combustion furnace 1 from the second connecting pipe 4, the exhaust gas to be burned can be diverted so that part of the exhaust gas enters each combustion chamber 8, and then a catalyst is added to each combustion chamber 8 separately, which makes it convenient to mix part of the exhaust gas with the catalyst; so as to improve the mixing effect of the exhaust gas to be burned and the catalyst, and further facilitate the subsequent exhaust gas combustion treatment.
