[0017] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0018] In the description of the present utility model, it should be noted that, unless otherwise specified, "multiple" means two or more; the orientations or positional relationships indicated by the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail", etc. are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present utility model. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0019] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0020] like Figure 1 As shown, the anti-cross-pressure system of the butyl acrylate production device provided by the utility model includes a condenser 1 and a reflux tank 2. The height of the condenser 1 is higher than the height of the reflux tank 2, and the height difference from the outlet of the condenser 1 to the inlet of the reflux tank 2 is 12.5 meters.

[0021] The condenser 1 is connected to the reflux tank 2 through the pipe 3. The lowest point of the pipe 3 is lower than the inlet of the reflux tank 2. The height difference from the lowest point of the pipe 3 to the inlet of the reflux tank 2 is 12 meters. The pipe 3 below the inlet of the reflux tank 2 is a U-shaped structure. By designing a downward U-shaped bend on the pipeline between the condenser 1 and the reflux tank 2, the height difference from the condenser 1 to the reflux tank 2 is increased, so that the height difference becomes 12.5+12=24.5 meters, and the pressure difference between the two devices is 24-5=19kpa, which cannot overcome the pressure difference caused by the 24.5-meter height difference. Therefore, the two devices, the condenser 1 and the reflux tank 2, will not be pressurized in series, which can avoid the problem of vacuum mismatch and is beneficial to the temperature operation of the device.

[0022] In order to better realize the utility model, the above structure is further optimized, and further includes an on-off valve 4 and a discharge valve 5. The on-off valve 4 is arranged on the pipeline 3, and the discharge valve 5 is arranged on the pipeline 3 between the on-off valve 4 and the reflux tank 2. It is used to control the on-off and emptying of the pipeline 3.

[0023] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
