Description

Technical Field

[0001] The utility model relates to the technical field of tubular reactors, in particular to precise synthesis control equipment for tubular reactors. Background Art

[0002] A tubular reactor is a continuously operated reactor that is tubular in shape and has a large aspect ratio. It is a plug flow reactor. This type of reactor can be very long. For example, the reactor tube for propylene dimerization is measured in kilometers. Tubular reactors have little backmixing and thus high volumetric efficiency. They are particularly suitable for situations where a high conversion rate is required or there are series side reactions.

[0003] During the use of a tubular reactor, liquid raw materials need to be added to the tubular reactor regularly and in a quantitative manner to achieve the purpose of accurately synthesizing multiple raw materials. The existing method of adding materials is mostly that the staff prepares the liquid raw materials to be added in advance, and then pours the liquid raw materials into the tubular reactor at a specific time. Since some tubular reactors are very long, this method of adding materials requires a lot of labor costs. Therefore, a more complete tubular reactor precision synthesis control equipment is needed to solve the above-mentioned problems. Utility Model Content

[0004] The utility model aims to provide a precise synthesis control device for a tubular reactor.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a tubular reactor precision synthesis control device, comprising a tubular reactor body, a plurality of equally spaced feed pipes are fixedly plugged into the top surface of the tubular reactor body, a first control valve is arranged at the bottom of the inner wall of the feed pipe, a second control valve is arranged at the middle of the inner wall of the feed pipe, a sealing plate is fixedly connected to the top of the feed pipe, a cylinder is fixedly connected to the bottom of the sealing plate, a water blocking plate is fixedly connected to the bottom end of the cylinder, and the outer peripheral side of the water blocking plate is closely attached to the feed pipe. The inner wall of the tubular reactor body is fixedly connected to a raw material box on the top surface on the left side of each feed pipe, and liquid raw materials are injected into the raw material box. A feed pipe is fixedly inserted on the top of the raw material box, and a pump body is fixedly connected to the bottom of the inner wall of the raw material box. The bottom end of the feed pipe is fixedly sleeved on the liquid outlet end of the pump body, and the top end of the feed pipe is fixedly inserted on the side wall of the feed pipe. The pump body can input the liquid raw material in the raw material box into the feed pipe through the feed pipe, and the end of the feed pipe away from the raw material box is located above the second control valve.

[0006] As a further solution of the utility model: a transparent glass plate is embedded in the front side of the feed pipe located above the second control valve, and a scale bar is arranged on the transparent glass plate.

[0007] As a further solution of the utility model: one end of the material delivery pipe located in the material feeding pipe is flush with the inner wall of the material feeding pipe, and a third control valve is provided on one end of the material delivery pipe located in the material feeding pipe.

[0008] As a further solution of the utility model: the volume of the feed pipe between the first control valve and the second control valve is smaller than the volume of the feed pipe between the second control valve and the sealing plate.

[0009] As a further solution of the utility model: a sealing ring is fixedly sleeved on the outer peripheral side of the water blocking plate.

[0010] By adopting the above technical solution, compared with the prior art, the beneficial effects of the utility model are:

[0011] The utility model can automatically add various liquid raw materials into the tubular reactor, and in the process of adding, a portion of raw materials can be prepared in advance to avoid the situation of untimely addition. The specific operation is to inject a variety of liquid raw materials into each raw material box in advance, and then open the cylinder in the corresponding feed pipe according to the amount of raw materials to be added, the cylinder will push the water blocking plate to move, and the position of the water blocking plate will be displayed on the scale bar. When the position of the water blocking plate on the scale bar reaches the position where the amount of raw materials needs to be added, the volume between the water blocking plate and the second control valve is the total amount of raw materials that need to be added. At this time, the pump body is opened again, and the pump body will move the liquid in the raw material box. The liquid raw material is transported to the cavity between the second control valve and the water blocking plate. When the liquid raw material fills the cavity, the third control valve and the pump body are closed, and then the second control valve is opened. The raw material above the second control valve will flow to the top of the first control valve. When the tubular reactor body needs to add raw materials, the staff only needs to remotely open the first control valve to add the raw materials to the tubular reactor body in a quantitative manner. When it is not necessary to add raw materials, the staff can prepare the raw materials to be added in advance in a quantitative manner in the above manner, let them stay above the second control valve, and when they need to be added, they only need to open the second control valve.

[0025] During the operation of the tubular reactor body 1, the staff can respectively inject a variety of liquid raw materials into each raw material box 3 in advance, and then open the cylinder 10 in the corresponding feed pipe 2 according to the amount of raw materials to be added, and the cylinder 10 will push the water blocking plate 12 to move, and the position of the water blocking plate 12 will be displayed on the scale bar 6. When the position of the water blocking plate 12 on the scale bar 6 reaches the position where the amount of raw materials needs to be added, the volume between the water blocking plate 12 and the second control valve 9 is the total amount of raw materials that need to be added. At this time, the pump body 7 is opened again, and the pump body 7 will transport the liquid raw materials in the raw material box 3 to the cavity between the second control valve 9 and the water blocking plate 12.

The raw materials above the second control valve 9 will flow to the top of the first control valve 8. When the tubular reactor body 1 needs to add raw materials, the staff only needs to remotely open the first control valve 8 to add the raw materials into the tubular reactor body 1 in a quantitative manner. When there is no need to add raw materials, the staff can prepare the raw materials to be added in advance in the above-mentioned manner and let them stay above the second control valve 9. When they need to be added, they only need to open the second control valve 9 to avoid untimely addition of materials. At this point, the entire workflow ends.
