Description

Technical Field

[0001] The utility model relates to the technical field of waste gas treatment and discloses a waste gas catalytic combustion furnace. Background Art

[0002] Catalytic combustion of waste gas is a technology that uses a catalyst to oxidize and decompose combustible substances in waste gas at a relatively low temperature, thereby purifying waste gas. This method can make harmful gases react with oxygen at a relatively low temperature and convert them into water and carbon dioxide, thereby reducing pollution to the environment. Catalytic combustion technology is widely used in the treatment of harmful waste gas and industrial waste gas due to its high purification efficiency, low combustion temperature, safety and environmental protection.

[0003] The patent with the patent authorization publication number CN208170414U discloses a catalytic combustion furnace for exhaust gas, whose structure includes a first support disc, a support column, a combustion furnace, a filter cover, an exhaust gas inlet, a blower, an exhaust gas inlet pipe, an upper cover, a heat storage body, a combustion chamber, a burner, a chimney, a connecting pipe, a second support disc, an exhaust pipe, a back-blowing blower and an inlet pipe. Although the above patent provides a circulating airflow for the exhaust chamber by installing a back-blowing blower next to the combustion furnace to accelerate the discharge of exhaust gas in the exhaust chamber, after the exhaust gas is catalyzed, the exhaust gas is directly discharged through the exhaust pipe, and the residual heat carried in the exhaust gas cannot be recovered, which easily leads to heat waste.

[0004] Therefore, there is a need for an exhaust gas catalytic combustion furnace that can utilize waste heat. Utility Model Content

[0011] In addition, it is particularly preferred that a valve is further included, and the oil tank is rotatably provided with a valve.

[0012] Compared with the prior art, the utility model provides a waste gas catalytic combustion furnace, which has the following beneficial effects: 1.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1: A waste gas catalytic combustion furnace, see Figure 1-Figure 5 , including a shell 1, a blower 2, a first bracket 3, a motor 4, a ventilation pipe 5, an oil tank 6, a partition 9, a placement rack 901 and a catalytic plate 10, the shell 1 is provided with the blower 2 by means of bolt connection, the shell 1 is fixedly connected with the first bracket 3, the first bracket 3 is provided with the motor 4 by means of bolt connection, the output shaft of the motor 4 is connected with the blower 2, the shell 1 is connected and communicated with a plurality of ventilation pipes 5, the shell 1 is provided with an oil tank 6 at the rear side, the oil tank 6 is provided with three flame-spraying ports 8, the shell 1 is fixedly connected with the partition 9, the shell 1 is provided with two placement racks 901 in a sliding manner, the placement rack 901 is provided with three catalytic plates 10, the top of the shell 1 is provided with an air outlet 11, the partition 9 is provided with two air guide plates 12, the oil tank 6 is rotatably provided with a valve 7, and the rotating valve 7 can control the oil output of the oil tank 6, thereby controlling the fire size of the flame-spraying port 8.

[0025] When it is necessary to catalyze the exhaust gas, the motor 4 and the blower 2 are turned on. The motor 4 drives the blower 2 to operate, and the exhaust gas is drawn into the ventilation pipe 5, and then enters the bottom of the shell 1 through the ventilation pipe 5. The valve 7 is turned to open the oil tank 6, so that the flame nozzle 8 burns the exhaust gas. The burned exhaust gas flows forward through the lower catalytic plate 10, and then the first catalysis is carried out. Then the exhaust gas flows upward through the upper catalytic plate 10, and the secondary catalysis is carried out. The catalyzed exhaust gas flows backward, and the air guide plate 12 limits the exhaust gas, so that the catalyzed exhaust gas is concentrated to flow to the ventilation pipe 5, and then the residual heat carried by the catalyzed exhaust gas heats the exhaust gas in the ventilation pipe 5, thereby avoiding heat waste and improving resource utilization efficiency. The catalyzed exhaust gas continues to flow through the air outlet 11 for discharge.

[0026] Example 2: Based on Example 1, please refer to Figure 1 and Figure 3 Two detection devices 13 are provided on the front side of the housing 1 by bolt connection. A lower warning light 14 is provided on the lower detection device 13, and an upper warning light 15 is provided on the upper detection device 13. A control device 16 is provided on the motor 4. The detection device 13 is electrically connected to the control device 16. When the detection device 13 detects that the catalytic plate 10 is not operating, the control device 16 controls the motor 4 to stop running, thereby stopping the catalysis.

[0027] When the catalytic plate 10 catalyzes the exhaust gas, the detection device 13 detects the exhaust gas. When the exhaust gas after catalysis does not reach the emission standard, the upper warning light 15 will light up, thereby reminding the staff to take corresponding measures in time.

[0028] See also Figure 4 A filter sponge 18 is arranged inside the shell 1, an activated carbon plate 19 is arranged inside the shell 1, and a dustproof net 17 is arranged inside the shell 1. The dustproof net 17 filters particulate matter carried in the exhaust gas after catalysis.

[0029] The catalyzed exhaust gas reaches the upper part of the housing 1, the activated carbon plate 19 adsorbs the organic matter in the exhaust gas, and the filter sponge 18 adsorbs the harmful substances remaining in the exhaust gas, thereby improving the exhaust gas catalysis effect.

[0030] See also Figure 6 Two second brackets 20 are fixedly connected to the right side of the housing 1. A rotating block 21 is rotatably arranged on the second bracket 20. A torsion spring 22 is sleeved on the second bracket 20 to reset the rotating block 21. The two ends of the torsion spring 22 are respectively connected to the rotating block 21 and the second bracket 20.

[0031] When the catalytic plate 10 needs to be replaced, the rotating block 21 is rotated outward, and the torsion spring 22 is deformed accordingly. The placement rack 901 is pulled to the right to pull it out from the inside of the housing 1, and the rotating block 21 is released. The torsion spring 22 returns to its original shape and the rotating block 21 is rotated inward to push out the catalytic plate 10, thereby facilitating the rapid removal of the catalytic plate 10 and improving the replacement efficiency. Then, a new catalytic plate 10 is replaced and the placement rack 901 is pushed to the left to reset.
