Embodiment Construction

[0014] 1. Installation location and connection relationship

[0015] The filling tank 1 of the present invention is cylindrical at the top and conical at the bottom; the diffuser pipe 2 is installed on the top of the filling tank 1 and communicates with the filling tank; the upper manhole 3 is located at the top edge of the filling tank; The lower part of the manhole 3 is welded with the inner wall of the full tank; the upper distribution plate 7 is located in the middle of the cylinder; the juice outlet 8 is located outside the full tank, the lower part communicates with the conical bottom of the full tank, and the upper part communicates with the full tank. The juice filling outlet pipe is connected; the cloth ring groove 5 is located between the upper distribution plate 7 and the inner wall of the full filling tank, and is welded on the inner wall of the full filling tank; the full juice outlet 6 is located at the same horizontal position of the cloth ring groove 5, connecte...

Abstract

The invention discloses a quick high-efficiency reverse carbonation tank for sugar manufacturing industry, which is characterized in that the carbonation tank is divided into three parts by an upper distribution plate and a lower distribution plate; a CO2 gas inlet tube is led into a distribution loop tube from top to bottom; a prelimed juice is subjected to principal liming and then fed into the middle of the carbonation tank in the tangential direction; a slag removal port is arranged at the bottom of the tank; CO2 gas bubbles upwards through the distribution loop tube; the limed juice moves into the middle of the carbonation tank in the tangential direction and then flows downwards, so that the CO2 bubbling upwards and the limed juice flowing downwards realize reverse operation. According to the quick high-efficiency reverse carbonation tank, the opposite flow directions of the CO2 and the limed juice realize quick high-efficiency carbonation based on favorable circulating mixed convection flows in reverse directions, ensure the sufficient and uniform reaction and achieve high CO2 absorptivity; the quick high-efficiency reverse carbonation tank has the advantages of low carbonation liquid level required, small volume, short retention time and high control stability, and can generate more calcium carbonate particles; and the overflowing phenomenon of the tank is less prone to occur. Thus, the quick high-efficiency reverse carbonation tank can achieve better carbonation effect.

Description

technical field [0001] The invention relates to a device for cleaning sugar juice in sugar production, in particular to a fast and efficient reverse filling tank. Background technique [0002] The sugar juice CO of the current sugar factory 2 Saturated equipment is generally used in carbonic acid sugar production process, but it is relatively seldom used in sulfurous acid process. Compared with the carbonation sugar production process, the sulfite sugar production process has more colloidal impurities, polyphenols, iron ions and other non-sugar impurities in the sugar juice, which are difficult to completely remove and the cleaning efficiency is low. The sulfite mixed juice contains a large amount of impurities other than sugar, which has a great impact on the subsequent cleaning and directly affects the product quality, while the CO of the sulfite mixed juice 2 The filling is relatively small, and the CO of the mixed juice 2 Filling is a new method of sulfite sugar produ...
