Description
TECHNICAL FIELD
[0001] The utility model belongs to pyrolysis gasification reaction technical field, especially relates to a pyrolysis gasification reaction device and reactor. BACKGROUND
[0002] The related art usually utilizes a tubular furnace to perform pyrolysis gasification reaction. Specifically, referring to Figure 1 , the specific procedure of pyrolysis gasification reaction is as follows: placing a thermal decomposition solid upstream of the tubular furnace and placing a sample to be reacted downstream of the tubular furnace; controlling the tubular furnace to be heated and introducing a carrier gas into the tubular furnace (the arrow in Figure 1 indicates the flow direction of the carrier gas), and the decomposition product obtained by thermal decomposition of the thermal decomposition solid will flow to the sample to be reacted under the action of the carrier gas and react with the sample to be reacted. Since the gas flow in the tubular furnace is composed of the carrier gas and the decomposition product obtained by thermal decomposition of the thermal decomposition solid, and the distribution of the decomposition product in the carrier gas is not uniform, i.e., the content of the decomposition product contacted by different regions of the sample to be reacted is different, the related art has the problem that the reaction degree of different regions of the sample to be reacted is different due to the different content of the decomposition product contacted by different regions of the sample to be reacted, and the obtained product is not uniform, and since the distribution of the decomposition product in the carrier gas may be different when performing pyrolysis gasification reactions of different batches, the related art also has the problem that the uniformity of the product obtained by pyrolysis gasification reactions of different batches is different, and the consistency of the product is poor.
[0003] Therefore, the prior art needs to be improved and developed. It should be noted that the above information disclosed in this part is only used to understand the background of the inventive concept, and therefore can contain information that does not constitute the prior art. INVENTION CONTENTS
[0004] The purpose of the present application is to provide a pyrolysis gasification reaction device and reactor, which can effectively solve the problem of different reaction degrees of different regions of the sample to be reacted due to different content of the decomposition product contacted by different regions of the sample to be reacted, and the problem of different uniformity of the product obtained by pyrolysis gasification reactions of different batches, and the problem of poor consistency of the product.

Therefore, the technical solution can effectively avoid the situation that the by-products in some regions are difficult or impossible to be cleaned due to the hindering effect of the baffle when the by-products can only be cleaned from one end of the reaction tank, thereby effectively improving the cleaning effect and convenience of the by-products.
[0011] Further, the first cover body and the second cover body are both in threaded connection with the reaction tank.
[0012] The first cover body and the second cover body of the technical solution are both in threaded connection with the reaction tank. Since threaded connection has the advantages of high reliability and convenient installation and removal, the technical solution can effectively improve the connection reliability of the first cover body and the second cover body with the reaction tank and the convenience of installing or removing the first cover body and the second cover body on the reaction tank.
[0013] Further, handles are arranged on the first cover body and the second cover body.
[0014] Since the handles are arranged on the first cover body and the second cover body of the technical solution, the handles on the first cover body and the second cover body can be used to put the reaction tank into the tube furnace or move the reaction tank out of the tube furnace, thereby effectively improving the convenience of putting the reaction tank into the tube furnace or moving the reaction tank out of the tube furnace.
[0015] Further, the distance between the baffle and the first cover is greater than the distance between the horizontal placement table and the first cover.
[0016] Further, the baffle is connected to the end of the horizontal placement table away from the first cover.
[0017] Further, the reaction tank is a cylindrical tank, and the horizontal placement table passes through the axis of the reaction tank.
[0018] Further, there is a gap between the first cover and the horizontal placement table, and the height of the air hole is less than the height of the horizontal placement table.
[0019] Further, the first cover is a cylindrical cover, and the air hole is a cylindrical hole, and the ratio of the diameter of the first cover to the diameter of the air hole is 8:1-10:1.

[0021] The pyrolysis gasification reactor provided by the application can effectively solve the problems of different reaction degrees of different regions of the sample to be reacted due to different contents of the decomposed substances contacted by different regions of the sample to be reacted, uneven final product, and poor consistency of the product due to different uniformities of the products obtained by different batches of pyrolysis gasification reactions.
[0022] As can be seen from the above, the pyrolysis gasification reaction device and the reactor provided by the application can make the decomposed substances fully contact the sample to be reacted through the cooperation of the baffle, the horizontal placement table and the air hole, so that different regions of the sample to be reacted are fully reacted, that is, the reaction degrees of different regions of the sample to be reacted are the same, and the sample to be reacted in different batches of pyrolysis gasification reactions can be fully reacted, that is, the uniformity of the product obtained by different batches of pyrolysis gasification reactions is the same, so the application can effectively solve the problems of different reaction degrees of different regions of the sample to be reacted due to different contents of the decomposed substances contacted by different regions of the sample to be reacted, uneven final product, and poor consistency of the product due to different uniformities of the products obtained by different batches of pyrolysis gasification reactions.

Of course, they are only examples and the purpose is not to limit the present application. In addition, the present application can refer to the same reference numerals and / or reference letters in different examples, and such repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed.
[0029] In a first aspect, as shown in the drawings, the present application provides a pyrolysis gasification reaction device applied in a tube furnace 10, which comprises: Figure 2
[0030] The reaction tank 1 is horizontally placed in the tube furnace 10, and a first cover 2 is detachably installed at one end thereof, and a baffle 3 and a horizontal placement table 4 are arranged in the reaction tank 1, and the baffle 3 is fixedly connected with the inner bottom wall of the reaction tank 1 and the horizontal placement table 4 at both ends thereof.
[0031] The first cover 2 has an air hole 5, the horizontal placement table 4 is used for placing a sample to be reacted 7, and the inner bottom wall of the reaction tank 1 located on the side away from the first cover 2 of the baffle 3 is used for placing a thermal decomposition solid 6.
[0032] The embodiment provides a pyrolysis gasification reaction device which is applied to a tubular furnace 10, can be an existing tubular furnace 10, can perform pyrolysis gasification reaction, and can heat objects in the tubular furnace 10. The reaction tank 1 of the embodiment is a tank body which can withstand high temperature, is horizontally placed in the tubular furnace 10, that is, the size of the reaction tank 1 is smaller than the size of the tubular furnace 10, and is detachably installed with the first cover body 2 at one end through buckle connection or bolt locking fixation. The reaction tank 1 is provided with the baffle 3 and the horizontal placement table 4. The baffle 3 is fixedly connected with the inner bottom wall of the reaction tank 1 and the horizontal placement table 4 at two ends, that is, the height of the baffle 3 is smaller than the height of the horizontal placement table 4. The baffle 3 and the horizontal placement table 4 of the embodiment can be an integral molding structure. The first cover body 2 of the embodiment is provided with the air hole 5. The hot decomposition solid 6 is placed on the inner bottom wall of the reaction tank 1 which is away from the first cover body 2 at one side of the baffle 3. The pyrolysis gasification reaction is equivalent to converting the corresponding material of the decomposition product from solid state to gaseous state. The sample to be reacted 7 of the embodiment can be a sample which needs to react with the decomposition product. The sample to be reacted 7 is placed on the horizontal placement table 4. That is, the hot decomposition solid 6 and the air hole 5 of the embodiment are respectively arranged at two sides of the sample to be reacted 7. It should be understood that, before starting the pyrolysis gasification reaction, the first cover body 2 of the embodiment can be first detached, then the hot decomposition solid 6 and the sample to be reacted 7 are placed in the reaction tank 1, and finally the first cover body 2 is installed on the reaction tank 1. After completing the pyrolysis gasification reaction, the first cover body 2 of the embodiment can be first detached, and then the reacted sample (the sample to be reacted 7 which completes the pyrolysis gasification reaction) is taken out.
[0033] The pyrolysis gasification reaction process of the pyrolysis gasification reaction device provided in the embodiment can be as follows: the first cover 2 is removed, and the thermal decomposition solid 6 and the sample to be reacted 7 are placed in the reaction tank 1; the first cover 2 is installed on the reaction tank 1, and the reaction tank 1 in which the thermal decomposition solid 6 and the sample to be reacted 7 are placed is horizontally placed in the tube furnace 10; the tube furnace 10 is vacuumized by using the vacuum pump, and the tube furnace 10 is sealed after the vacuumization is completed; the tube furnace 10 is controlled to be heated to start the pyrolysis gasification reaction; after the pyrolysis gasification reaction is completed (for example, when the temperature in the tube furnace 10 reaches the target temperature for a duration that reaches a preset duration, it is considered that the pyrolysis gasification reaction is completed), the tube furnace 10 is controlled to stop heating and is cooled; the gas pressure in the tube furnace 10 is restored to the normal pressure; the tube furnace 10 is opened, and the reaction tank 1 containing the reacted sample is taken out; the first cover 2 is removed, and the reacted sample is taken out. It should be understood that, since the first cover 2 of the embodiment has the air hole 5, that is, the reaction tank 1 is in communication with the tube furnace 10 through the air hole 5, after the vacuumization is completed, the reaction tank 1 is in a vacuum state, and the pyrolysis gasification reaction is equivalent to converting the decomposition product corresponding to the material into a gaseous state, so in the process of the pyrolysis gasification reaction, a gas flow including only the gaseous decomposition product is formed in the reaction tank 1, and since the thermal decomposition solid 6 and the air hole 5 are respectively arranged on the two sides of the sample to be reacted 7, that is, the gas flow including only the gaseous decomposition product needs to pass through the sample to be reacted 7 to flow out of the air hole 5, so the embodiment can make the decomposition product fully contact with the sample to be reacted 7, so that different regions of the sample to be reacted 7 are fully reacted. It should also be understood that the reaction tank 1 of the embodiment is placed in the tube furnace 10, that is, the reaction tank 1 is in contact with the tube furnace 10, so the tube furnace 10 can transmit heat to the reaction tank 1 by contact conduction, and the thermal decomposition solid 6 of the embodiment is placed in the reaction tank 1, that is, the thermal decomposition solid 6 is in contact with the reaction tank 1, so the reaction tank 1 can transmit heat to the thermal decomposition solid 6 by contact conduction, so as to heat the thermal decomposition solid 6.
[0034] The pyrolysis gasification reaction device provided in the present application makes the decomposition product fully contact with the sample to be reacted 7 through the cooperation of the baffle 3, the horizontal placement table 4 and the air hole 5, so that different regions of the sample to be reacted 7 are fully reacted, that is, the reaction degree of different regions of the sample to be reacted 7 is the same, and the sample to be reacted 7 in different batches of pyrolysis gasification reactions can be fully reacted, that is, the uniformity of the product obtained in different batches of pyrolysis gasification reactions is the same, so the present application can effectively solve the problems that the reaction degree of different regions of the sample to be reacted 7 is different due to the different contents of the decomposition product contacted by different regions of the sample to be reacted 7, and the product obtained is not uniform, and the uniformity of the product obtained in different batches of pyrolysis gasification reactions is different, and the consistency of the product is poor.
[0035] In some preferred embodiments, the other end of the reaction tank 1 is detachably provided with a second cover 8. In this embodiment, the other end of the reaction tank 1 is detachably provided with the second cover 8 by means of buckle connection, bolt locking or the like. Since the inner wall of the reaction tank 1, the baffle 3 and the horizontal placement platform 4 are all in contact with the decomposed substance during the pyrolysis and gasification reaction, the inner wall of the reaction tank 1, the baffle 3 and the horizontal placement platform 4 can all form by-products. After the pyrolysis and gasification reaction is completed, the by-products need to be cleaned. Since the two ends of the reaction tank 1 in this embodiment are detachably provided with the first cover 2 and the second cover 8 respectively, the first cover 2 and the second cover 8 can be removed before the by-products are cleaned. In this embodiment, the by-products can be cleaned from both ends of the reaction tank 1. Therefore, this embodiment can effectively avoid the situation that the baffle 3 hinders the cleaning of the by-products in some areas when the by-products can only be cleaned from one end of the reaction tank 1, thereby effectively improving the cleaning effect and convenience of the by-products.
[0036] In some preferred embodiments, the first cover 2 and the second cover 8 are both threadedly connected with the reaction tank 1. In this embodiment, the first cover 2 and the second cover 8 are both threadedly connected with the reaction tank 1. Since the threaded connection has the advantages of high reliability and convenient installation and removal, this embodiment can effectively improve the connection reliability of the first cover 2 and the second cover 8 with the reaction tank 1 and the convenience of installing or removing the first cover 2 and the second cover 8 on the reaction tank 1.
[0037] In some preferred embodiments, handles 9 are provided on the first cover 2 and the second cover 8. Since the first cover 2 and the second cover 8 in this embodiment are both provided with handles 9, the reaction tank 1 can be put into or taken out of the tube furnace 10 by using the handles 9 on the first cover 2 and the second cover 8, thereby effectively improving the convenience of putting the reaction tank 1 into or taking it out of the tube furnace 10.
[0038] In some preferred embodiments, the distance between the baffle 3 and the first cover 2 is greater than the distance between the horizontal placement platform 4 and the first cover. Specifically, the baffle 3 in this embodiment can be connected with the middle part of the horizontal placement platform 4.
[0039] In some preferred embodiments, the baffle 3 is connected with the end of the horizontal placement platform 4 away from the first cover 2.
[0040] In some preferred embodiments, the reaction tank 1 is a cylindrical tank, and the horizontal placement platform 4 passes through the axis of the reaction tank 1. In this embodiment, the height of the horizontal placement platform 4 is equal to half the diameter of the reaction tank 1.
[0041] In some preferred embodiments, the first cover 2 is a cylindrical cover, the vent hole 5 is a cylindrical hole, and the ratio of the diameter of the first cover 2 to the diameter of the vent hole 5 is 8:1-10:1. The ratio of the diameter of the cover to the diameter of the vent hole 5 in this embodiment is preferably 9:1.
[0042] In some preferred embodiments, the baffle 3 is integrally formed with the horizontal placement platform 4, and the baffle 3 is detachably installed in the reaction tank 1. The baffle 3 in this embodiment can be detachably installed in the reaction tank 1 by means of buckle connection or bolt locking. Since the baffle 3 in this embodiment is integrally formed with the horizontal placement platform 4 and the baffle 3 is detachably installed in the reaction tank 1, when cleaning the by-products, the baffle 3 and the horizontal placement platform 4 can be removed from the reaction tank 1 by detaching the baffle 3, so as to avoid the baffle 3 and the horizontal placement platform 4 from hindering the cleaning of the by-products on the inner wall of the reaction tank 1, thereby effectively improving the cleaning effect of the reaction tank 1. Since the baffle 3 and the horizontal placement platform 4 can be removed from the reaction tank 1 in this embodiment, the cleaning space of the baffle 3 and the horizontal placement platform 4 is increased, and thus the cleaning convenience of the baffle 3 and the horizontal placement platform 4 is effectively improved.
[0043] In some preferred embodiments, there is a gap between the first cover 2 and the horizontal placement platform 4, and the height of the vent hole 5 is less than the height of the horizontal placement platform 4. This embodiment is equivalent to lengthening the gas path of the decomposition product in the reaction tank 1, so as to reduce the flow rate of the decomposition product, thereby making the decomposition product more fully contact with the sample 7 to be reacted.
[0044] As can be seen from the above, the pyrolysis gasification reaction device provided by the present application makes the decomposition product fully contact with the sample 7 to be reacted through the cooperation of the baffle 3, the horizontal placement platform 4 and the vent hole 5, so that different regions of the sample 7 to be reacted are fully reacted, i.e., the reaction degree of different regions of the sample 7 to be reacted is the same, and different batches of the sample 7 to be reacted in the pyrolysis gasification reaction can be fully reacted, i.e., the uniformity of the products obtained by different batches of the pyrolysis gasification reaction is the same. Therefore, the present application can effectively solve the problems that the reaction degree of different regions of the sample 7 to be reacted is different due to the different contents of the decomposition product contacted by different regions of the sample 7 to be reacted, and the uniformity of the products obtained by different batches of the pyrolysis gasification reaction is different, and the consistency of the products is poor.

[0047] As can be seen from the above, the pyrolysis gasification reactor provided by the present application enables the decomposed substance to fully contact the sample 7 to be reacted through the cooperation of the baffle 3, the horizontal placement table 4 and the air hole 5, so that different regions of the sample 7 to be reacted are fully reacted, that is, the reaction degrees of different regions of the sample 7 to be reacted are the same, and the sample 7 to be reacted in different batches of pyrolysis gasification reactions can be fully reacted, that is, the uniformity of the product obtained by different batches of pyrolysis gasification reactions is the same, so that the present application can effectively solve the problems that the reaction degrees of different regions of the sample 7 to be reacted are different due to different contents of the decomposed substance contacted by different regions of the sample 7 to be reacted, the final obtained product is not uniform, and the consistency of the product is poor due to different uniformities of the product obtained by different batches of pyrolysis gasification reactions.
