Description

Technical field:

[0001] The utility model relates to the field of negative pressure distributors, in particular to a negative pressure balanced distributor. Background technology:

[0002] A distributor is a device that allows fluids such as gas, solid or liquid to enter from a single inlet and then be evenly distributed to multiple outlets.

[0003] There is no gas phase distributor in the traditional process, and the economic cost is very high during long-term use.

[0004] And through observation and experiment, it was found that the gas volume at the top of the distillation tower was too large, there was a bias flow phenomenon, the heat exchange area was not fully utilized, the equipment cost was too high, and the circulating water consumption was large, which affected the cooling effect of the cooler, caused a large waste of energy and was very unfavorable to the continuous stability of BDO production. Utility model content:

[0005] The utility model aims to provide a negative pressure balanced distributor.

[0006] The utility model is implemented by the following technical solutions:

[0007] A negative pressure balanced distributor comprises a distillation tower, an exhaust main pipe, a negative pressure balanced distributor, distributor internals, a total air inlet and a connecting piece, wherein the output end of the distillation tower is fixedly connected to one end of the exhaust main pipe, the other end of the exhaust main pipe is fixedly connected to and communicates with the total air inlet, the total air inlet is fixedly installed on the top of the negative pressure balanced distributor, the distributor internals are fixedly installed in the negative pressure balanced distributor, a plurality of shunt pipes are fixedly connected to the bottom end of the negative pressure balanced distributor, a connecting piece is fixedly installed at the connection between the exhaust main pipe and the total air inlet, the cross-section of the connecting piece is T-shaped, the connecting piece is fixedly connected to the total air inlet by bolts, and a sealing rubber pad is filled between the connecting piece and the total air inlet.

[0008] Preferably, the bottom end of the connector is fixedly sleeved with a sealing member, the sealing member is ring-shaped, and the outer wall of the sealing member is tightly fitted with the inner wall of the main air inlet.

[0009] Preferably, one end of the exhaust main pipe extends into the main air inlet, and a plurality of T-shaped rods are fixedly connected to the end of the exhaust main pipe extending into the main air inlet, a slidingly connected moving plate is commonly sleeved on the plurality of T-shaped rods, a spring is sleeved on each T-shaped rod, a contactor is fixedly connected between the bottom ends of the plurality of T-shaped rods, and a blocking block is fixedly installed on the top of the moving plate.

[0010] The advantages of the utility model: a newly added negative pressure balanced distributor allows the airflow to pass through the distributor before entering the cooling system, which can prevent the airflow from being biased, thereby avoiding affecting the cooling effect and reducing economic costs. At the same time, in order to ensure the normal operation of the distributor, a seal is used to further increase the sealing effect. At the same time, a new contactor is added. If a seal leakage problem occurs, the contactor will not contact the moving plate due to the reduced pressure, thereby triggering an alarm, making it convenient for subsequent maintenance personnel to repair it in time. Description of the drawings:

[0011] Figure 1 It is a schematic diagram of the structure of the utility model.

[0012] In the figure: distillation tower 1, exhaust main pipe 2, negative pressure balanced distributor 3, distributor internals 4, main air inlet 5, connecting piece 6, sealing piece 7, T-bar 8, moving plate 9, spring 10, contactor 11, blocking block 12. Specific implementation method:

[0013] like Figure 1 As shown, a negative pressure balanced distributor comprises a distillation tower 1, an exhaust main pipe 2, a negative pressure balanced distributor 3, a distributor internal 4, a total air inlet 5 and a connector 6, wherein the output end of the distillation tower 1 is fixedly connected to one end of the exhaust main pipe 2, the other end of the exhaust main pipe 2 is fixedly connected to and communicated with the total air inlet 5, the total air inlet 5 is fixedly installed on the top of the negative pressure balanced distributor 3, the distributor internal 4 is fixedly installed in the negative pressure balanced distributor 3, and the bottom end of the negative pressure balanced distributor 3 is fixedly connected to There are multiple branch pipes, and a connector 6 is fixedly installed at the connection between the exhaust main pipe 2 and the main air inlet 5. The cross-section of the connector 6 is T-shaped. The connector 6 is fixedly connected to the main air inlet 5 by bolts. A sealing rubber pad is filled between the connector 6 and the main air inlet 5. When working, the gas enters the negative pressure balanced distributor 3 along the distillation tower 1 and the exhaust main pipe 2, and after being diverted by the distributor internals 4 installed inside the negative pressure balanced distributor 3, it is discharged along multiple branch pipes, thereby realizing balanced diversion.

[0014] The bottom end of the connector 6 is fixedly connected to the seal 7. The seal 7 is ring-shaped. The outer wall of the seal 7 is tightly fitted with the inner wall of the main air inlet 5. The connector 6 is set to a T-shape, and the protruding part extends into the main air inlet 5. The newly added seal 7 is tightly fitted with the inner wall of the main air inlet 5 to further ensure the sealing.

A contactor 11 is fixedly connected between the bottom ends of the plurality of T-shaped rods 8, and a blocking block 12 is fixedly installed on the top of the moving plate 9. When the negative pressure suction does not leak and remains sufficient, the moving plate 9 maintains a downward pressing posture due to the suction, and maintains contact with the contactor 11, and the spring 10 is in a stressed and compressed state. When the suction is insufficient, that is, when a leak occurs at the connection, part of the pressure will be lost to the outside, so that the elastic force of the spring 10 is slightly released, so that the moving plate 9 cannot contact with the contactor 11, thereby triggering an alarm.
