Description

Technical Field

[0001] This invention relates to the field of ammonia-hydrogen kiln technology, and in particular to an intelligent kiln based on ammonia-hydrogen zero-carbon combustion technology. Background Technology

[0002] In the high-temperature industrial sector of ceramic tile firing, kilns are the core thermal equipment. For a long time, they have relied on fossil fuels such as coal and natural gas as their main energy sources. Their combustion process emits a large amount of carbon dioxide, making them a major source of industrial carbon emissions. With the advancement of the global carbon neutrality goal, carbon-free fuels, represented by ammonia and hydrogen, have become an important direction for the clean energy transformation of kilns. The combustion products of ammonia are mainly nitrogen and water, while the combustion product of hydrogen is only water. Neither of them produces carbon dioxide, and they have the potential to achieve zero-carbon combustion.

[0003] However, ammonia is toxic and corrosive, and hydrogen has an extremely wide explosion limit and extremely low ignition energy. In fuel transportation systems, there are numerous connection points between the main gas pipeline and the branch gas inlet pipes. Affected by the periodic thermal expansion and contraction of the kiln, combustion vibration, and pipeline stress fluctuations, these points are prone to becoming high-risk points for leakage. Traditional flange gasket seals and single-layer seal structures are prone to creep relaxation and aging failure under high-temperature variable operating conditions, making it difficult to maintain long-term airtightness. Summary of the Invention

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The mechanical electrode contact detection of the leakage pressure alarm mechanism and the pneumatic valve drive of the inflation sealing mechanism do not rely on external control signals, fundamentally eliminating the risk of safety function failure caused by electrical faults. From the occurrence of leakage to alarm triggering and then to the active expansion and sealing of the airbag, the entire process is driven by the same leakage pressure source in series, realizing a rapid linkage safety closed loop of detection, alarm and sealing, which greatly improves the intrinsic safety level of the ammonia hydrogen fuel transportation system.

[0013] A rigid sealing cavity formed by bolts fastening the upper and lower sealing mechanisms, along with the precise snap-fit ​​positioning of right-angle snap-fit ​​strips, straight-edge snap-fit ​​strips and right-angle snap-fit ​​grooves, strictly confines leaking gas within the sealed cavity, preventing escape. The leakage pressure alarm mechanism uses purely mechanical pressure to drive the pressure against the sliding block, causing the second electrode contact to conduct with the first electrode contact, achieving direct, zero-delay sensing of leaking gas pressure and local audible and visual alarms. Simultaneously, the leakage pressure information is uploaded to the central control platform, realizing full-link intelligent monitoring.

[0014] The inflation sealing mechanism relies entirely on the pressure of the leaking gas itself as the driving force. It pushes the pressure of the gas supply pipe against the sliding ball and the pressure of the air inlet pipe against the sliding ball to open the one-way valve. It automatically inflates the upper gas supply pipe sealing airbag, the lower gas supply pipe sealing airbag, the upper air inlet pipe sealing airbag, and the lower air inlet pipe sealing airbag, and performs back pressure sealing and airtightness enhancement at the connection of the leaking section. It can complete the active emergency response without external power supply or control signal. Attached Figure Description

[0020] The sealing alarm device 4 includes an upper sealing mechanism 41, a lower sealing mechanism 42, a leakage pressure alarm mechanism 43, and an inflation sealing mechanism 44.

The lower air supply sealing plate 421 and the upper air inlet pipe sealing plate 416 are both provided with the lower air inlet pipe sealing plate 426 through them. The top of the outer wall of the lower air supply sealing plate 421 is provided with evenly distributed lower bolt fixing ears 422. The lower air supply sealing plate 421 is provided with lower air supply pipe sealing airbags 423 at both ends of the inner wall of the lower air supply sealing plate 421. The inner wall of the lower air inlet pipe sealing plate 426 is far away from the lower air supply pipe sealing plate 426. One end of the gas supply sealing plate 421 is provided with a lower air intake pipe sealing airbag 427. A straight edge snap-fit ​​groove 425 is opened on the straight edge of the top of the lower gas supply sealing plate 421 away from the lower air intake pipe sealing plate 426.

It is fastened to the upper sealing mechanism 41 by the lower bolt fixing ears 422 evenly distributed on the top and the bolts. It works with the lower air intake pipe sealing plate 426 extending vertically on the same side to complete the semi-enclosed coverage of the branch pipe.

A slidable pressure abutment sliding block 437 is installed between the two. The top of the block is fixed with a second electrode contact 438 aligned with the first electrode contact 434. The two electrodes are driven to contact and conduct by pure mechanical pressure, so as to realize the direct sensing and local alarm of the leakage gas pressure.

[0028] The inflation sealing mechanism 44 includes an inflation tube 441 for the gas supply pipe sealing airbag, a gas supply pipe top limiting ring 442, a gas supply pipe pressure contact sliding ball 443, an inflation tube 444 for the air inlet pipe sealing airbag, an air inlet pipe pressure contact sliding ball 445, an air inlet pipe top limiting ring 446, and a pipe bottom limiting ring 447.

[0029] The inflation sealing mechanism 44 consists of symmetrically distributed air supply pipe sealing airbag inflation pipes 441 and a separately provided air inlet pipe sealing airbag inflation pipe 444, forming a dual inflation channel. Both pipes extend from the leakage pressure main pipe 431 above the upper limit ring 435 inside the pipe. Inside both the air supply pipe sealing airbag inflation pipe 441 and the air inlet pipe sealing airbag inflation pipe 444, there are annular air supply pipe top limiting rings 442 and 446, which are in contact with spherical air supply pipe pressure contact sliding balls 443 and air inlet pipe pressure contact sliding balls 443. Ball 445 forms a pressure-driven one-way valve structure. The bottom is uniformly supported and limited by the bottom pipe limiting ring 447. Relying on the leakage pressure itself as the triggering power, it can automatically inflate the sealing airbags at all levels without external power supply and control signal. This realizes the optimization from passive sealing to active enhanced sealing. The inflation sealing mechanism 44 can directly convert the leakage pressure itself into the active expansion force of the airbag. At the same time as the leakage alarm is triggered, the airtightness of the sealing node is strengthened by pure mechanical pneumatic means.
