The utility model belongs to the field of natural gas chemical industry in general, and particularly relates to an acetylene furnace reaction chamber with adjustable reaction time.
Background
The partial oxidative cleavage of natural gas to acetylene is typically a reaction sequence and the intermediate product is the target product acetylene. The oxidation reaction process takes a very short time, and is a millisecond-scale transient reaction. Therefore, the control requirement on the reaction process is very strict, and problems are brought to too short or too long reaction time, such as insufficient reaction caused by too short reaction time, and further cracking of the intermediate product acetylene into hydrogen and carbon black caused by too long reaction time.
Because of the volume, height and other parameters of the reaction chamber, the residence time of the reaction gas in the reaction chamber is directly related. Therefore, when designing the reaction chamber of the acetylene furnace, the size of the reaction chamber needs to be combined with the air inflow, air speed, proportion and the like of the raw material gas to carry out strict experimental measurement and simulation accounting of dynamics and thermodynamic parameters.
Therefore, in order to ensure the optimization of the oxidation-cracking reaction time, for the acetylene reaction device with a solidified structure, on one hand, the optimized oxidation reaction time can be ensured only by keeping stable and unchanged process parameters including the raw material gas grade composition, the oxygen ratio, the speed, the temperature and the like, and on the other hand, the productivity is fixed and cannot be changed at will.
For the reaction chamber with a variable structural size, the reaction time can be controlled through structural change, so that the production load of the device can be flexibly adjusted and the device can adapt to the change of other process conditions.

Therefore, the utility model aims to provide an acetylene furnace reaction chamber with adjustable reaction time, which is characterized in that the acetylene furnace reaction chamber is designed into an upper reaction chamber and a lower reaction chamber, the lower reaction chamber can move relative to the upper reaction chamber, the overall height of the reaction chamber is changed, the total height of the reaction chamber is regulated to a reasonable value according to the size, the proportion, the speed, the productivity and the like of the air inflow in actual production, the residence time of gas in the reaction chamber is regulated to be within the optimal reaction time interval, the yield of the reaction product is ensured, and the device can flexibly regulate the production load and the productivity of the device, adapt to the change of the process parameters of raw gas and the like and simultaneously ensure the maximization of the yield by changing the height of the reaction chamber.
The technical scheme of the utility model is that the reaction chamber of the acetylene furnace with adjustable reaction time comprises the upper part of the reaction chamber and the lower part of the reaction chamber; the top end of the upper part of the reaction chamber is connected with an acetylene furnace burner plate, and the lower part of the reaction chamber is connected with a quenching system; the upper part of the reaction chamber is separated from the lower part of the reaction chamber; the upper part or the lower part of the reaction chamber is provided with a height adjusting component; the height adjusting component is used for enabling the upper part of the reaction chamber or the lower part of the reaction chamber to move in parallel in the vertical direction, so that the distance between the lower part of the reaction chamber and the upper part of the reaction chamber is controlled and adjusted, and the regulation and control of the gas reaction time are realized through the height adjustment of the reaction chamber of the acetylene furnace; the reaction chamber of the acetylene furnace with adjustable reaction time is arranged in a closed cavity structure.

the utility model provides an acetylene furnace reaction chamber, which belongs to a part of components in an acetylene furnace reactor for preparing acetylene from natural gas. Therefore, the design of the airtight connection between the upper part of the reaction chamber and the lower part of the reaction chamber may not be considered, because even if the lower part of the reaction chamber needs a certain distance from the upper part of the reaction chamber because of the height adjustment, part of the reaction gas escaping from the connection part of the two is still in the cavity structure.
Further, the upper part and the lower part of the reaction chamber comprise an inner wall and an outer wall; the separation arrangement of the upper part of the reaction chamber and the lower part of the reaction chamber comprises an inner wall separation arrangement and an outer wall separation arrangement; the inner wall and the outer wall are made of carbon steel, and a cavity structure is arranged between the inner wall and the outer wall and is used for introducing cooling circulating water.
The cavity structure on the reaction chamber wall is used for loading cooling circulating water, so that the cooling wall structure of the reaction chamber is realized, the wall temperature of the reaction furnace is controlled in a lower temperature range, and hidden danger caused by overhigh temperature of the furnace wall is avoided. Only the inner wall and the outer wall of the upper part of the reaction chamber and the inner wall and the outer wall of the lower part of the reaction chamber are separated and arranged at the same time, so that the lower part of the reaction chamber can vertically and vertically move relative to the upper part in a regulating manner.

The reaction pressure of the reaction chamber is 0-0.1 MPa, and the reaction temperature is 1300-1500 ℃.
It can be seen that the acetylene furnace reaction chamber provided by the utility model belongs to a part of components in the acetylene furnace reactor for preparing acetylene from natural gas. Therefore, the design of airtight connection between the upper part of the reaction chamber and the lower part of the reaction chamber can be omitted, because even if the lower part of the reaction chamber needs a certain distance from the upper part of the reaction chamber because of height adjustment, part of the reaction gas escaping from the connection part of the reaction chamber and the reaction chamber is still in the cavity structure, and the gas is discharged from a cracking gas outlet after the reaction.

Detailed Description
The present utility model will be described in further detail below with reference to the drawings and detailed description for the purpose of enabling those skilled in the art to understand the utility model better.
Example 1
The structure of the reaction chamber of the acetylene furnace with adjustable reaction time is shown in figure 1, the reaction chamber is divided into an upper part and a lower part, the lower part is provided with a height adjusting part, preferably an adjustable fixing part such as a bolt, and the reaction chamber specifically comprises: a reaction chamber upper portion 101 and a reaction chamber lower portion 102. The cross section of the reaction chamber is regular hexagon, the inner wall is of a downward closing structure in the vertical direction, the inclination angle is 7 degrees, namely the included angle between the inner wall and the vertical line is 7 degrees.
The upper part of the reaction chamber upper part 101 is adjacent to an acetylene reaction furnace mixing zone which is used for realizing uniform mixing of hydrocarbon and oxygen, and then enters the reaction chamber (comprising the reaction chamber upper part 101 and the reaction chamber lower part 102) through a burner plate with n regular triangle burners uniformly distributed, and oxidation reaction occurs in the reaction chamber, so that acetylene and other byproducts are generated. The pyrolysis gas rapidly passes through the reaction chamber along the common central axis direction of the upper part 101 and the lower part 102 of the reaction chamber, and is cooled down by the extraction cooling medium in the extraction cooling zone, so as to terminate the reaction. The outer walls of the extraction cooling areas adjacent to the lower part 102 of the reaction chamber are provided with nozzles, extraction cooling medium is axially sprayed into the center of the furnace from the nozzles, and pyrolysis gas is uniformly contacted with the extraction cooling medium to be cooled.
The reaction chamber comprising the upper part 101 and the lower part 102 adopts a cold wall structure, circulating water enters the circulating jacket from the water inlet 1 at the lower part of the reaction chamber, then leaves the circulating jacket from the water outlet 2 at the lower part of the reaction chamber, and part of heat in the acetylene furnace is taken away, so that the furnace wall is maintained in a low-temperature state. The circulating water enters the upper water inlet 3 of the reaction chamber through a hose connected with the lower water outlet 2 of the reaction chamber, and leaves the circulating jacket from the upper water outlet 4 of the reaction chamber after part of heat at the upper part of the reaction chamber is circularly taken away.
When the capacity of the apparatus was designed to be 1 ten thousand tons/year and the production load was 100%, the height of the reaction chamber was 400mm, and the inscribed circle in the upper portion 101 of the reaction chamber had a size of Φ600mm. In this case, the optimum oxidation time is 20ms, and the highest acetylene yield can be obtained.
Further, the reaction chamber lower part 102 may be adjusted in the up-down position by a height adjusting member 5 such as a bolt. Specifically, when the production load of the apparatus is increased to 120%, the amount of the corresponding reaction furnace gas (including natural gas and oxygen) is increased, the gas velocity is increased, and the residence time of the gas, i.e., the oxidation reaction time, is too short, which may cause insufficient reaction progress and decrease in acetylene yield. At this time, the lower part 102 of the reaction chamber is moved downward away from the upper part of the reaction chamber by adjusting the height adjusting part 5, such as a bolt, so that the overall height of the reaction chamber is increased by 10%, and the extraction cooling zone immediately adjacent to the bottom of the lower part 102 of the reaction chamber is correspondingly translated downward, thereby increasing the time of passing the pyrolysis gas through the reaction chamber and maintaining the optimal reaction time of 20ms and product yield.
Further, when the production load of the device is reduced to 80%, the air inflow (comprising natural gas and oxygen) of the corresponding reaction furnace is reduced, the air speed is reduced, the residence time of the gas, namely the oxidation reaction time, is too long, so that the reaction is not terminated timely, the acetylene product is further cracked into hydrogen and carbon black, and the acetylene yield is reduced. At this time, the lower part 102 of the reaction chamber is closed to the upper part of the reaction chamber by adjusting the height adjusting part 5 such as a bolt, the overall height of the reaction chamber is reduced by 10%, and the extraction cooling zone immediately adjacent to the bottom of the lower part 102 of the reaction chamber is correspondingly translated upwards, so that the time for the pyrolysis gas to pass through the reaction chamber is shortened, and the optimal reaction time of 20ms and the product yield are maintained.
In another embodiment of the utility model, the cross section of the reaction chamber is circular, the inclination angle of the inner wall is 0 degrees, i.e. the inner wall is vertical.
Example 2
The structure of the reaction chamber of the acetylene furnace with adjustable reaction time is shown in figure 1, and the reaction chamber is divided into an upper part and a lower part, and specifically comprises: the bottom ends of the reaction chamber lower part 102 and the reaction chamber upper part 101 are provided with bolts for fixing the reaction chamber lower part 102 away from or near the reaction chamber upper part 101. The cross section of the reaction chamber is regular hexagon, the inner wall is of a downward closing structure in the vertical direction, the inclination angle is 7 degrees, namely the included angle between the inner wall and the vertical line is 7 degrees.
The upper part of the reaction chamber upper part 101 is adjacent to an acetylene reaction furnace mixing zone which is used for realizing uniform mixing of hydrocarbon and oxygen, and then the mixture enters the reaction chamber (comprising the reaction chamber upper part 101 and the reaction chamber lower part 102) through a burner plate with n regular triangle burners uniformly distributed, and oxidation reaction occurs in the reaction chamber to generate acetylene and other byproducts. The pyrolysis gas rapidly passes through the reaction chamber along the common central axis direction of the upper part 101 and the lower part 102 of the reaction chamber, and is cooled down by the extraction cooling medium in the extraction cooling zone, so as to terminate the reaction. The outer wall of the extraction cooling zone adjacent to the lower part of the reaction chamber is provided with a nozzle, the extraction cooling medium is axially sprayed into the center of the furnace from the nozzle, and the pyrolysis gas is uniformly contacted with the extraction cooling medium to cool.
The reaction chamber comprising the upper part 101 and the lower part 102 adopts a cold wall structure, circulating water enters the circulating jacket from the water inlet 1 at the lower part of the reaction chamber, then leaves the circulating jacket from the water outlet 2 at the lower part of the reaction chamber, and part of heat in the acetylene furnace is taken away, so that the furnace wall is maintained in a low-temperature state. The circulating water enters the upper water inlet 3 of the reaction chamber through a hose connected with the lower water outlet 2 of the reaction chamber, and leaves the circulating jacket from the upper water outlet 4 of the reaction chamber after part of heat at the upper part of the reaction chamber is circularly taken away.
When the production load of the device is 1 ten thousand tons/year, the height of the reaction chamber is 400mm, and the inscribed circle in the upper part 101 of the reaction chamber has a dimension phi 600mm. At this time, the content of C2-type gas (e.g., ethane) in the raw natural gas was 0.5%. In this case, the oxidation reaction time was set to an optimum value of 20ms, and the highest acetylene yield was obtained.
When the content of C2 gas (such as ethane) in the raw natural gas is increased to 2.8%, the retention time of the gas required, namely the oxidation reaction time, is shortened because the cracking difficulty is reduced. At this time, the lower part 102 of the reaction chamber is close to the upper part 101 of the reaction chamber by adjusting the height adjusting part, the overall height of the reaction chamber is reduced by about 2%, and the extraction cooling zone adjacent to the bottom of the lower part 102 of the reaction chamber is correspondingly translated upwards, so that the time for the pyrolysis gas to pass through the reaction chamber is shortened, and the optimal reaction time and product yield are maintained.
The foregoing description of embodiments of the utility model has been presented for purposes of illustration and description, and is not intended to be exhaustive or limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the various embodiments described. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claims.
