RU3936U1 - AUTOMATIC LINE FOR PREPARING THE PUMP WATER TO RETURN IT TO DIFFUSION - Google Patents

Abstract

Automatic line for preparing pulp-pressed water for its return to diffusion, including the following devices connected in series: diffusion heater, settling tank, characterized in that the line is equipped with series-connected defecosaturators, a filter for cleaning from defecosaturation sediment, and a fine membrane filter placed after the heater. The line according to claim 1, characterized in that the fine membrane filter is made in the form of a closed circulation circuit.

Description

Automatic line for the preparation of pulp press water for its return to diffusion

The proposed technical solution relates to the field of food processing of industry and can be used to purify process liquids in the production of sugar from sugar beets; for example, to purify pulp press water when preparing it for return to diffusion j There is an automatic line for preparing pulp press water for its return to diffusion 11 gM; Uilin , Sugar technology Mg Food industry LUL GGS 47cS), including series-connected devices -. Diffusion filter Sampler.

The disadvantage of this technical solution is the low quality of cleaning from microorganisms and high fuel consumption due to the need to raise the temperature to the temperature of sterilization, large losses of sucrose, due to the vital activity of microorganisms

the most advanced solution to the proposed technical solution is an automatic line for preparing pulp press water for its return to diffusion (IgM iilin Food industry, Mu1Ub7 glsls5a: riskhkch including the following series-connected devices: diffusion.tank filter.heater

the disadvantage of this technical solution is the low quality of cleaning from

microorganisms and high fuel consumption t e

The aim of the proposed technical solution is to increase the degree of purification of pulp press water from microorganisms to reduce fuel consumption by eliminating from the process of the sterilizing operation - processing sulfitation;. water with sulfur dioxide) and the exclusion from the process of sterilizing substances in the form of formalin, chlorine and TgPg

This goal is achieved by the fact that the line is equipped with a series-connected. NNMI defecosaturator, filter for purifying water from defecaturation sediment, and a membrane filter for fine purification of high molecular weight compounds, substances of colloidal dispersion, microorganisms and suspended solids whose particles do not settle in the gravity field and are not cleaned by any other means, while the fine filter is placed after the heater.

A block diagram of the proposed technical solution is shown in the drawing; It includes sequentially connected devices: diffusion-1, sedimentation tank-: | Defecosurator -4 filter for cleaning of defecosaturation sediment - oh, heater - b, fine filter -7 j including a circular pump - 6i section of membrane devices -3, pressure regulator - th capacity of the circulation circuit f.

It has been found that i aooTa lines are carried out by the following oorasis: from pulp obtained from a diffusion apparatus i by pressing, pulp press water is obtained; it is sent to sump 1, E where it is cleaned of pulp; Purified. the water is sent to the heater 5, in which it is heated to the temperature of defccation; the heated water is sent to the defecator 4, in which the water is treated with lime and carbon dioxide, in order to precipitate the dissolved non-sugars. In the filter 5, the defecation cake is removed from the water, after which the water is fed into the heater which stabilizes the temperature within the range of 50-70 ° С; from the heater, the water is sent to a fine filter / consisting of series-connected devices: circulation 8 |; water is supplied to the section of the membrane apparatus of UaIri In this case, the bCin- enters the section,; . / current of purified water, a. two streams emerge from the section — the filtrate and the concentrate. — The filtrate purified on iuu from microorganisms, the pulp jelly water is cleaned by high purity from high molecular and colloidal compounds from Ht 3KOMO molecular compounds precipitated with lime and carbon dioxide, suspended solids which do not settle in the field of gravity by other means and are not removed i on Shi; oncentrate - this retains the filter membrane. When the concentration of substances retained by the membrane reaches its limit value, the concentrate is discharged. - from the circulating membrane circuit b during operation, the pressure in the circulating circuit is regulated by the regulator 10 g. The amount of water to be cleaned in one cycle depends on the volume of the circulating circuit. The filtrate from the membrane filter is directed to the consumer, in this case the diffusivity apparatus of the proposed technical solution is characterized by the degree of purification the degree of purification from microorganisms makes 1007o, from suspended solids - IOU7a, from high molecular weight and colloidal substances - bb-7b from the initial value -.- Purification from microorganisms made it possible to reduce fuel consumption for heating to the sterilization temperature, to remove the saponin-foaming agent from water, and to eliminate the use of environmentally harmful disishiculating substances in the form of chlorine formaldehyde and Т; пО - I -.

Claims (2)
