Description

Technical Field

[0001] The invention relates to the technical field of ultra-high temperature catalytic cracking devices for gases, and in particular to an ultra-high temperature catalytic cracking device for gases. Background Art

[0002] Most halogen compounds are artificially synthesized products. Some organic halogen compounds are toxic in themselves and can cause cancer in the human body. Their biodegradation rate is very low, resulting in accumulation in the ecosystem. Some volatile organic halogen compounds have a great destructive effect on the ozone layer and have a serious impact on the environment and human health. These halogen compounds are listed as chemicals harmful to humans and the environment, and their use is prohibited or limited. They are pollutants that are key controlled by countries around the world.

[0003] Halogen compounds are generally divided into inorganic halogens and organic halogens. Traditional detection methods can only perform partial detection according to the difference in chemical structure, that is, oxygen is introduced into the reaction tube as an auxiliary gas for combustion and cracking catalysis. However, when the hydrogen content in the gas to be detected is too high, it is very easy to produce hydrogen-oxygen explosion at high temperature;

[0004] In order to concentrate temperature and prevent heat loss, the existing tubular furnace is generally sealed to a high degree. When a hydrogen-oxygen explosion occurs, the internal pressure is relatively high, and an implosion is easily formed, which has low safety. Therefore, a gas ultra-high temperature catalytic cracking device is proposed to solve the above-mentioned problems. Summary of the invention

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the present invention provides a gas ultra-high temperature catalytic cracking device, which has the advantages of high safety, etc., and solves the problem that the existing tubular furnace is generally highly sealed in order to concentrate temperature and prevent heat loss. When a hydrogen-oxygen explosion occurs, the internal pressure is relatively high, which easily causes implosion and has low safety.

[0056] High borosilicate glass has high structural strength and good heat resistance, which can avoid cracking during high-temperature catalysis.

[0057] Working principle:

[0058] Step 1: Before use, push the grip 302 to the left, the grip 302 drives the connecting rod 301 to move left, so that the connecting rod 301 is released from the bottom shell 201, and the top shell 202 can be flipped up through the hinge, the explosion-proof plate 502 is inserted through the block 501, and the catalytic cracking reactor 1 is placed for subsequent ventilation use;

[0059] Step 2: When in use, the gas to be detected is introduced into the high temperature reaction chamber 101 through the sample gas pipe 104, and water vapor is introduced into the high temperature reaction chamber 101 through the water vapor pipe 102 to mix with the gas to be detected, and then hydrogen or oxygen is introduced through the reaction gas pipe 103 to assist the catalytic reaction, and at the same time, the heating tube 7 is started to heat the high temperature reaction chamber 101, so that the gas in the high temperature reaction chamber 101 reaches a catalytic cracking reaction, so that it is cracked into halogen and then discharged from the small diameter end of the high temperature reaction chamber 101 for detection;

[0060] Step 3: If a hydrogen-oxygen explosion occurs in the high-temperature reaction chamber 101, the top shell 202 and the bottom shell 201 of the tubular furnace 2 are buckled together through the connecting rod 301 to prevent the pressure generated by the implosion from expanding and opening. At the same time, the pressure inside the tubular furnace 2 pushes the sealing cover 406 to separate from the bottom shell 201, opening the pressure relief port, so that the internal pressure of the tubular furnace 2 is discharged from the fitting port between the sealing cover 406 and the bottom shell 201. When the pressure is discharged, the fire extinguishing cotton 408 is first released to extinguish the possible open flame, and the generated pressure gas is guided upward and downward by the gas guide shell 407 to generate horizontal thrust, and the upward pressure gas is guided and consumed obliquely upward by the gas guide plate 8, further reducing the hazard caused by the implosion, and the fragments of the catalytic cracking reactor 1 that are broken are blocked by the explosion-proof plate 502 to prevent them from flying out to the side facing the staff, thereby protecting the personal safety of the staff.
