Description

Technical Field

[0001] The utility model relates to the technical field of combustible gas transportation, in particular to a novel tar condensation-proof combustible gas pipeline connection structure. Background Art

[0002] Combustible gas pipeline is a pipeline system used to transport combustible gas. It is mainly composed of pipeline body, connecting parts, valves, control devices and other parts. The pipeline body is usually made of metal materials or high-performance plastics. Metal pipelines have the characteristics of high strength and high pressure resistance, and are suitable for long-distance, high-pressure transportation. Plastic pipelines have the advantages of corrosion resistance and good flexibility, and are mostly used in low-pressure distribution networks of urban gas.

[0003] However, the existing devices have the following problems:

[0004] Existing rotary continuous carbonization furnaces encounter a common problem during operation: tar condenses and accumulates in the channel connecting the combustible gas outlet due to temperature fluctuations, eventually leading to blockage. This blockage not only affects the normal operation efficiency of the equipment but also triggers a series of chain reactions, rendering the entire system inoperable and forcing operators to shut down for maintenance. This unplanned downtime not only increases maintenance costs but also causes delays in production schedules, seriously affecting overall production efficiency and economic benefits. Therefore, effectively solving the tar condensation blockage problem has become the key to improving the reliability and production efficiency of rotary continuous carbonization furnaces.

[0005] Therefore, in order to solve the above problems, a new type of combustible gas pipeline connection structure that prevents tar condensation is proposed. Utility Model Content

[0006] The purpose of the utility model is to provide a novel tar condensation-resistant combustible gas pipeline connection structure to solve the problem of combustible gas transportation in the prior art mentioned in the above background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a new type of anti-tar condensation combustible gas pipeline connection structure, comprising a connecting pipe, the outer side of the connecting pipe is fixedly connected to a combustible gas outlet, the front of the connecting pipe is fixedly connected to a high-temperature flue gas inlet, the rear of the connecting pipe is fixedly connected to a flue gas outlet, and the top of the connecting pipe is fixedly connected to an inspection port.

[0008] Preferably, an air intake pipe is fixedly connected to the lower part of the connecting pipe, and a gas and combustible gas inlet is fixedly connected to the lower part of the air intake pipe.

[0009] Preferably, a bolt hole is provided on the outer side of the gas and combustible gas inlet, and the air inlet pipe and the gas and combustible gas inlet are hollow structures.

[0010] Preferably, an air outlet pipe is fixedly connected to the outside of the combustible gas outlet, a fixing rod is fixedly connected to the outside of the air outlet pipe, a fixing ring is fixedly connected to the outside of the air outlet pipe, and a bolt hole is provided on the outside of the fixing ring.

[0011] Preferably, the high-temperature flue gas is fixedly connected to a sealing ring in front of the flue gas inlet, and the high-temperature flue gas is fixedly connected to a flue gas connecting ring in front of the flue gas inlet.

[0012] Preferably, an outlet connecting pipe is fixedly connected to the front of the smoke outlet, and an outlet fixing ring is fixedly connected to the rear of the smoke outlet.

[0013] Preferably, a fixing nut is fixedly connected to the outer side of the inspection port, and a fixing bolt is fixedly connected to the inner side of the fixing nut.

[0014] Compared with the existing technology, the beneficial effects of the present invention are: the present invention optimizes the design of the existing channel structure, adds a shell on the outside of the channel, and uses the hot flue gas generated by the carbonization furnace itself to effectively heat the channel. Experimental verification shows that this method not only successfully prevents the condensation and precipitation of tar in the channel and solves the problem of channel blockage, but also improves the thermal utilization rate of the furnace body. In this way, it not only reduces the frequency of equipment being forced to shut down due to channel blockage, reduces maintenance costs, but also improves overall production efficiency. More importantly, this optimized design achieves the effect of energy saving and consumption reduction by maximizing the use of existing thermal energy, bringing higher economic benefits and better environmental benefits to the enterprise. Overall, this improvement measure not only improves equipment reliability and production efficiency, but also embodies the concept of efficient resource management and sustainable development.

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

[0024] See also Figure 1-Figure 5 , an embodiment provided by the utility model:

[0025] A novel tar-condensation-resistant combustible gas pipeline connection structure comprises a connecting pipe 1, the outer side of the connecting pipe 1 is fixedly connected to a combustible gas outlet 2, the front of the connecting pipe 1 is fixedly connected to a high-temperature flue gas inlet 3, the rear of the connecting pipe 1 is fixedly connected to a flue gas outlet 4, and the top of the connecting pipe 1 is fixedly connected to an inspection port 5.

[0026] Furthermore, an outlet pipe 201 is fixedly connected to the outside of the combustible gas outlet 2, a fixing rod 202 is fixedly connected to the outside of the outlet pipe 201, a fixing ring 203 is fixedly connected to the outside of the outlet pipe 201, and bolt holes are provided on the outside of the fixing ring 203, which can transport natural gas to the flue gas inlet 3.

[0027] Furthermore, the high-temperature flue gas is fixedly connected to a sealing ring 301 in front of the flue gas inlet 3, and the high-temperature flue gas is fixedly connected to a flue gas connecting ring 302 in front of the flue gas inlet 3, so that the flue gas in the device can complete a cycle.

[0028] Furthermore, an outlet connecting pipe 401 is fixedly connected to the front of the smoke outlet 4, and an outlet fixing ring 402 is fixedly connected to the rear of the smoke outlet 4, so that the smoke in the device can complete a cycle.

[0029] Furthermore, a fixing nut 501 is fixedly connected to the outside of the inspection port 5, and a fixing bolt 502 is fixedly connected to the inside of the fixing nut 501, so that the pipeline can be inspected.

[0030] Working principle: When the device is in use, the combustible gas first enters the device from the combustible gas inlet 101 and enters the subsequent equipment from the combustible gas outlet 2. The high-temperature flue gas enters the channel from the flue gas inlet 3 and the flue gas outlet 4. The flue gas will complete a cycle in the component, fully heating the inner layer of combustible gas, and then enter the subsequent pipeline from the flue gas outlet 4 and the high-temperature flue gas from the flue gas inlet 3. When the equipment is shut down, the combustible gas pipeline can be fully maintained to increase the life of the equipment. In the above process, the combustible gas at the inspection port 5 is heated by the external hot smoke through the internal channel. The inlet and outlet positions of the hot smoke can be modified according to the on-site conditions, and the width of the interlayer needs to be adjusted according to the inlet temperature of the hot smoke to achieve the ideal combustible gas temperature, which can meet the requirements of heating the combustible gas to above a specific temperature to ensure that tar cannot be precipitated.
