Description

Technical Field

[0001] This application relates to the field of direct-fired furnaces, and more particularly to a TO direct-fired furnace. Background Technology

[0002] TO direct-fired furnaces generate heat through the combustion of auxiliary fuel, raising the temperature of exhaust gas to the reaction temperature, causing VOCs to oxidize and decompose at high temperatures. Its core principle is direct combustion, requiring no catalyst and capable of converting VOCs into carbon dioxide and water at high temperatures of 750-1200℃, with a conversion rate exceeding 99%.

[0003] A search revealed a Chinese patent with authorization announcement number CN219328094U, which discloses a plate-type TO direct-fired furnace, comprising a shell, a high-temperature furnace chamber, a corrugated tube radiant heat exchange module, and a plate heat exchanger, wherein the high-temperature furnace chamber, the corrugated tube radiant heat exchange module, and the plate heat exchanger are sequentially arranged inside the shell.

[0004] The plate-type TO direct-fired furnace in the aforementioned patent has the following shortcomings: Although the device can make the waste gas and combustion oxygen mix more evenly in the high-temperature furnace through the annular baffle and flow equalization plate, resulting in more complete combustion and more thorough decomposition of the waste gas, organic waste gas often contains particulate impurities and other solid particles. However, the device does not have a centralized treatment and collection device for the solid particles in the organic waste gas, which will cause the solid particles to accumulate inside the direct-fired furnace, making the equipment prone to failure and leaking into the external gas. Particulate impurities not only pollute the environment but may also have adverse effects on human health, such as irritating the eyes, nose and throat, and causing symptoms such as headaches and dizziness.

A support frame 10 is fixedly installed on one side of the L-shaped tube 7. A collection box 8 for collecting solid particles is provided on the support frame 10. The collection box 8 is located at the bottom of the mesh 9, and the top of the collection box 8 is open. A second filter screen 22 for classifying wastewater and particles is provided inside the collection box 8.

[0034] In use, the first filter 12 can block and filter solid particles in organic waste gas, and the particles fall into the collection box 8 through the mesh 9 and are located on the second filter 22, thus completing the collection of solid particles.

[0035] Reference Figure 2-4The spraying mechanism includes a water pump 15 fixedly installed on an L-shaped pipe 7. A suction pipe 16 is fixedly installed at one end of the water pump 15's suction port, and an outlet pipe 17 is fixedly installed at one end of the water pump 15's outlet. A connecting pipe 18 is fixedly installed at one end of the outlet pipe 17. Both ends of the connecting pipe 18 pass through the top of the L-shaped pipe 7 and are fixedly installed with corresponding diversion pipes 19. Multiple corresponding nozzles 20 are symmetrically fixedly installed at the bottom of the diversion pipes 19. A water tank 13 is fixedly installed at the top of the L-shaped pipe 7. A tank cover 14 is provided on the top of the water tank 13. A scale 21 is sealed and embedded on one side of the water tank 13. The scale 21 is made of transparent glass. A handle 23 is fixedly installed on one side of the storage box 8. An anti-slip pad is provided on the handle 23.

[0036] In use, the water pump 15 is started by controlling the pump. The water pump 15's suction port absorbs water from the water tank 13 through the suction pipe 16 and delivers it to the connecting pipe 18 through the outlet pipe 17. The water is then delivered to the diversion pipe 19 through the connecting pipe 18, and sprayed by multiple nozzles 20 on the diversion pipe 19. This process also helps to settle dust and other impurities in the organic waste gas, reducing the amount of dust and other impurities entering the equipment and thus extending its service life. Furthermore, the second filter 22 can be used to classify and filter wastewater and particles.

[0037] Reference Figure 4-5 The installation mechanism includes two sliding grooves 24 symmetrically opened on the support frame 10, and a corresponding sliding block 25 is slidably installed in each of the two sliding grooves 24. Both sliding blocks 25 are fixedly installed with the storage box 8. A corresponding positioning plate 26 is fixedly installed on the inner walls of both sides of the storage box 8.

[0038] In use, by pulling the handle 23, the storage box 8 can be disassembled through the cooperation of the sliding groove 24 and the sliding block 25, and the solid particles remaining on the second filter screen 22 can be discharged. This reduces the amount of solid particles entering the equipment and improves the stability during use.

[0039] The implementation principle of a TO direct-fired furnace according to an embodiment of this application is as follows: During use, organic waste gas enters through the L-shaped pipe 7 and passes through the first filter screen 12, which can block and filter the solid particles in the organic waste gas. The solid particles fall into the collection box 8 through the mesh 9 and are located on the second filter screen 22, thus completing the collection of solid particles. By pulling the handle 23, the collection box 8 can be disassembled through the cooperation of the sliding groove 24 and the sliding block 25, and the solid particles remaining on the second filter screen 22 can be discharged. Therefore, it can reduce the number of solid particles entering the equipment and improve the stability during use.

[0040] When organic waste gas enters the L-shaped pipe 7, the water pump 15 is started by controlling the pump. The water pump 15's suction port absorbs water from the water tank 13 through the suction pipe 16 and delivers it to the connecting pipe 18 through the outlet pipe 17. The water is then delivered to the diversion pipe 19 through the connecting pipe 18, and sprayed by multiple nozzles 20 on the diversion pipe 19. This process also helps to settle dust and other impurities in the organic waste gas, reducing the amount of dust and other impurities entering the equipment and thus extending the equipment's service life. Furthermore, the second filter 22 can be used to classify and filter wastewater and particles.

[0041] The exhaust gas undergoes a first heating process via heat exchanger 2. After this initial heating, the exhaust gas exits through the internal exhaust gas outlet and enters the furnace body 1, flowing towards the high-temperature furnace chamber 5. As it passes through the outside of the metal bellows 4, which functions as a thermal radiation heat exchanger, the exhaust gas undergoes a second heating process. This allows the exhaust gas to be preheated to a higher temperature before being sent to the burner of the burner 6 through the internal exhaust gas passage. By heating the exhaust gas twice before it is purified in the high-temperature furnace chamber 5, considerable fuel can be saved, thereby reducing operating costs.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
