In a first embodiment according to the present invention, there is provided a ground torch system 100 comprising a plurality of ground burners 110 and a radiation protection fence 120. Wherein, a plurality of ground combustor 110 are arranged into at least two, and the quantity of the ground combustor 110 in every row is at least two, and radiation protection rail 120 is around setting up in the outside of this a plurality of ground combustor 110, and radiation protection rail 120 has certain height moreover, can block the heat radiation to the external world when the flame burns. It can be understood that the ground burner 110 is an atmospheric diffusion burner, the combustible gas is ejected from the small holes of the ground burner 110, and then the combustible gas sucks the surrounding air by the pressure of the gas to burn, and sufficient air needs to be provided for the burner in order to ensure that the combustible gas can be sufficiently burnt.
Specifically, as shown in FIG. 1, in the first embodiment, the ground flare system 100 has 6 rows of ground burners 110, the number of the ground burners 110 in each row is 25, and the radiation-proof enclosure 120 surrounds the 6 rows of ground burners 110 and encloses a combustion area capable of burning gas.
The radiation protection fence 120 has a certain gap with the ground, through which the external air can enter the combustion area, and the arrows in fig. 1 indicate the direction and quantity of the external air entering the combustion area, so that it can be seen that the ground burners 110 in the first and sixth rows located at the outer side can conveniently receive sufficient air, and the ground burners 110 in the second to fifth rows located at the middle area can not receive sufficient air, so that the ground burners 110 at the middle area may be incompletely combusted, and the combustible gas may be directly discharged into the air, thereby polluting the environment.
Specifically, taking the floor burners 110 in the second to fifth rows as an example, the floor burners 110 in each row need to take effective air from the row gaps on the left and right sides thereof when burning gas. The effective amount of air Q1 depends on the distance L between adjacent rows of floor burners 110 and the height of the gap between the radiation fence 120 and the floor.
In order to allow the middle ground burner 110 to acquire enough air, the distance L between two adjacent rows of ground burners 110 is at least 6 meters, for example 8 meters, 12 meters in the present embodiment. Further, in each row, the adjacent ground burners 110 need to be fired during the combustion of the gas, and therefore, the distance between the adjacent ground burners 110 in each row is not excessively large, and in the present embodiment, the distance d between the adjacent ground burners 110 in each row is at most 2 meters, for example, 1.8 meters, 1.6 meters. It will be appreciated that, in order to ensure that the floor burners 110 can ignite the combustible gas in a timely manner when discharging the combustible gas, a beacon light may be provided on each row of floor burners 110.
According to the utility model discloses a ground torch system 100, including a plurality of ground combustors 110 and radiation protection rail 120, this a plurality of ground combustors 110 set up among radiation protection rail 120 with the mode of arranging into a row, and through injecing the distance between the adjacent two ground combustors 110 of two between the ground combustor 110 that two adjacent lists and every row between the distance can make ground combustor 110's position arrange more rationally, when ground torch system 100 handles big discharge capacity combustible gas, ground combustor 110 can receive sufficient air, can avoid ground combustor 110 to appear burning phenomenon such as insufficient and smoking when combustion gas, reduce the pollution to the environment.
Further, the distance between the ground burners 110 of two adjacent rows may be 8 to 10 meters, for example 9 meters.
Still further, the distance between adjacent ground burners 110 in each column may be 1.6 to 1.65 meters, such as 1.63 meters.
The height of the radiation protection fence 120 needs to be higher than the flame height generated by the ground burner 110, so that the leakage of heat radiation can be avoided and the light pollution can be reduced. In this embodiment, the height of the radiation protective enclosure 120 is 15 to 18 meters, such as 15 meters, 17 meters. In addition, the radiation protective enclosure 120 can be constructed of a metallic material that is not easily deformed at high temperatures.
Further, the distance between adjacent ground burners 110 in each row is the same and the number of burners is the same, whereby the length of each row of ground burners 110 in the ground flare system 100 is the same.
In one embodiment, when it is required to arrange 150 ground burners, in the first embodiment, as shown in fig. 1, 6 rows of ground burners 110 are provided in the radiation protection fence 120, the number of the ground burners 110 in each row is 25, the distance between the ground burners 110 in adjacent two rows is 7 m, the distance between the adjacent ground burners 110 in each row is 1.6 m, and the radiation protection fence 120 is configured as a square and surrounds the outer sides of the 6 rows of ground burners 110, thereby forming a size of 50m × 50m — 2500m2A square combustion zone.
However, the air passage of the ground-based combustor 110 of the middle region in the first embodiment is relatively long, and further improvements in the arrangement of the ground-based flare system 100 are required in order to enable the ground-based combustor 110 of the middle region to acquire sufficient air.
Thus, in the second embodiment, as shown in FIG. 2, the ground flare system 200 has 10 rows of ground burners 210, the number of ground burners 210 in each row being 15, and the radiation protection enclosures 220 are configured as rectangles and disposed around the outside of the 10 rows of ground burners 110, forming a substantially rectangular combustion area.
Arrows in fig. 2 indicate the direction and amount of outside air entering the combustion area, and it can be seen that the ground burners 210 in the first and third columns on the outer side can conveniently receive sufficient air, while the ground burners 210 in the second to ninth columns in the middle area can not receive sufficient air, but the air channel in the middle is shorter than that of the square combustion area in the first embodiment, which is more favorable for the flow and propagation of air.
In a specific example, when it is required to arrange 150 ground burners, in the second embodiment, as shown in fig. 2, 10 rows of ground burners 210 are provided in the radiation protection fence 220, the number of the ground burners 210 in each row is 15, and two adjacent rows are providedThe distance between the ground burners 210 is 7 m, the distance between the adjacent ground burners 210 in each row is 1.6 m, and the radiation protection fence 220 is constructed in a rectangular shape and surrounds the outside of the plurality of ground burners 210, thereby forming a size of 73.5m × 134 m-2499 m2A rectangular combustion zone.
As can be seen from the above two specific embodiments, when the number of burners is determined, the ground burners 210 located in the middle can more conveniently receive sufficient air in the rectangular combustion area, and thus, the arrangement of the ground flare system 200 of the rectangular area is superior to that of the ground flare system 200 of the square.
Illustratively, the ratio of the number of ground based burners in each row to the number of rows of ground based burners may be at least 3:2, within which range the ground based burners located in the middle zone are able to receive sufficient ambient air.
As shown in fig. 3 and 4, the ground burners 210 in the same row are connected to the same exhaust pipe 230, and each exhaust pipe 230 is provided with a control valve 240. Combustible gas can be delivered to the ground burner 210 through the exhaust pipe 230, and the control valve 240 can control the on-off of the exhaust pipe 230, so that workers can control the delivery of the combustible gas according to the working condition requirements.
Preferably, the ground burners 210 in each row in the ground flare system 200 are configured in the same stage, the ground burners 210 in at least two rows are divided into at least two stages, and the ground burners 210 in the same stage start burning simultaneously, and the ground burners 210 in different stages start burning sequentially. For example, the exhaust pipes 230 of the ground burners 210 configured as the same stage may simultaneously turn on or off the delivery of the combustible gas. As one implementation, low-stage number ground burners 210 may initiate combustion preferentially.
Further, as shown in fig. 5, in the third embodiment according to the present invention, there are 10 rows of ground flare system 300, the 10 rows of ground flare system are divided into 2-stage combustion system, the ground flare system located at the leftmost side is the first stage, the rest 9 rows of ground flare system are the second stage, and the ground flare system 300 has only the maximum and minimum discharge conditions. For example, in the case of the minimum emission condition, only the leftmost ground burners of the first stage may be turned on, and in the case of the maximum emission condition, all the rows of ground burners including the first and second stages may be turned on.
Furthermore, the plurality of ground burners are arranged in at least three rows, and the number of the stages of the ground burners is reduced from the outside to the inside in the arrangement direction of the rows. Specifically, as shown in fig. 6, in the fourth embodiment according to the present invention, there are 10 rows of ground burners arranged in the horizontal direction in the ground flare system 400, and the 10 rows of ground burners are divided into 5-stage combustion systems, and the number of stages of the ground burners located at the outer side is higher than that of the ground burners located at the middle in the horizontal direction (i.e., in the arrangement direction of the rows). Illustratively, the ground burners located on the left and right sides of the outermost side have the fourth and fifth stages, respectively, and the ground burners located in the middle have the second, fourth, and third stages in this order. As one implementation, as shown in fig. 4, the 5 th column from left to right is the (r) th stage, the 4 th column from left to right is the (r) th stage, the 6 th column from left to right is the (r) th stage, and then, the leftmost 3 column is the (r) th stage, and the rightmost 4 columns are the (r) th stage. In the working process, the combustion system of the first level is started preferentially, and then the combustion system of the subsequent level is opened gradually according to the discharge amount of combustible gas.
In actual working conditions, the maximum discharge amount (also called design condition) of the ground flare system is generally started when accidents such as fire or power failure happen to petrochemical plants, the accidents occur rarely, and the discharge duration is short. In most cases, the ground flare is used for processing combustible gas generated by the petrochemical device under normal working conditions, the discharge amount is relatively small, and only part of the ground burner needs to be opened. Therefore, in the embodiment, under the condition of normal operation, only the middle ground burner needs to be started, and the ground burner is far away from the radiation-proof fence, so that the heat radiation to the radiation-proof fence can be reduced, and sufficient air can be obtained. It will be appreciated that the ground burners near the sides of the radiant barrier will only be turned on at maximum discharge.
The present invention has been described in terms of the above embodiments, but it is to be understood that the above embodiments are for purposes of illustration and description only and are not intended to limit the invention to the described embodiments. Furthermore, it will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and that many more modifications and variations are possible in light of the teaching of the present invention and are within the scope of the invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
