Description

Technical Field

[0001] The utility model relates to a chemical distillation tower provided with a steam buffer mechanism, belonging to the technical field of chemical distillation. Background Art

[0002] Distillation towers are chemical equipment made of rare metal materials such as titanium and its alloys. They have the characteristics of high strength, high toughness, high temperature resistance, corrosion resistance, and light specific gravity. Therefore, they are widely used in chemical industry, petrochemical industry, metallurgy, light industry, textile, alkali production, pharmaceuticals, pesticides, electroplating, electronics and other fields.

[0003] The existing publication number CN110694294B is a distillation tower with a steam buffer function. In this device, a buffer mechanism is installed on the outside of the distillation tower body. The buffer mechanism reduces the impact of steam, preventing the steam from directly entering the condenser due to excessive impact and impacting the parts in the condenser and reducing the service life of the condenser, which is beneficial to protecting the condenser; a cooling mechanism is installed in the buffer mechanism. Through the coordinated use of the cooling mechanism and the buffer mechanism, the buffer mechanism is used to reduce the impact of steam and the cooling mechanism is used to reduce the temperature of steam, thereby facilitating the subsequent condensation of steam; an anti-sticking mechanism is slidably connected to the distillation tower body and is located below the gathering mechanism. The anti-sticking mechanism is used to The structure is pushed open back and forth, thereby preventing the gathering mechanism from being blocked, which is conducive to the gathering of steam. However, the buffer structure adopted in this device mainly uses the method of steam pushing the fan blades to rotate to reduce the impulse of steam. However, the gap is small when the steam is discharged through the first connecting pipe, which will increase the impulse of the steam, and no limiting device is set on the outside of the fan blades, so that the steam drives the fan blades to rotate rapidly, and it is not possible to buffer the steam well, so that the impulse of the steam is still too large when entering the condenser; and the gathering mechanism set in this device will cause the steam to be continuously squeezed, so that the pressure in the distillation tower is increased, and the steam is ejected at high pressure, which will further increase the discharge impulse of the steam, which is not conducive to the use of steam buffer discharge and has the risk of overpressure.
