Embodiment Construction

[0022] Such as Figure 1 ~ Figure 3 As shown, a three-channel lye distributor: a cylinder body (5), a top plate (2) and a bottom plate (7) are welded to form a closed tank. Such as image 3 As shown, in order to reduce the stress at the welding seam, the top plate (2) and the bottom plate (7) are connected to the cylinder (5) with a flanging butt joint structure; the top plate (2) is provided with a lye inlet pipe (1) to ensure the The molten lye level inside is stable, and the lye inlet pipe adopts an enlarged diameter structure to reduce the lye flow rate, namely: the lye inlet pipe (1) adopts a stepped tubular structure with a lower end diameter larger than an upper end diameter. Three lye outlet pipes (16) are arranged on the bottom plate (7), and the lye outlet pipe (16) has a certain inclination so that the materials can be completely drained.

[0023] The molten salt coil (13) and steam coil (14) are installed outside the tank for heating. The molten salt coil (13) and st...

Abstract

The invention relates to a three-channel alkali liquor distributor. The three-channel alkali liquor distributor adopts a technical scheme that: a cylinder body, a top plate and a bottom plate are welded together to form a closed tank; the top plate is provided with an alkali liquor inlet pipe, and the bottom plate is provided with three alkali liquor outlet pipes; a molten salt pipe coil and a steam pipe coil are arranged outside the tank, and the steam pipe coil is clung to the molten salt pipe coil; the wall of the tank is provided with a manhole, a thermometer interface, a nitrogen inlet and three steam sweeping pipes; the lower part of the tank is divided into three cavities by using a division plate, each cavity corresponds to one alkali liquor outlet pipe, the three steam sweeping pipes correspond to the three alkali liquor outlet pipes respectively, and each steam sweeping pipe is concentric with the corresponding alkali liquor outlet pipe; and an alkali liquor overflow cylinder is arranged in the tank, the lower end of the alkali liquor inlet pipe extends into the alkali liquor overflow cylinder, the alkali liquor overflow cylinder is provided with an outlet, and a rotating device passes through the bottom plate and is connected with the alkali liquor overflow cylinder. The three-channel alkali liquor distributor is easy to maintain, is safe and stable to operate, and has a long service life, and the molten alkali liquor can be switched at any time according to production requirements.

Description

Technical field [0001] The invention relates to a distribution device for changing the flow direction of molten alkali through the adjustment of a rotating device at high temperature. The device can be used together with a prilling tower, a flake alkali machine, and a dissolving tank. For the production requirements of the device, it can either go to the dissolution tank to prepare 50% liquid caustic, or to remove the flake caustic soda, or go to the granulation tower to granulate the caustic soda. Background technique [0002] With the increase in domestic consumption of flake caustic and granular caustic soda, the demand for molten caustic is increasing; however, existing equipment cannot guarantee that the flow of molten caustic can be adjusted at any time during the continuous production process to produce different products. Therefore, an optimized device is needed, which can be used together with the prilling tower, flake caustic soda machine, and dissolving tank at the sam...
