Description

Sistema de minimización de residuos.Waste minimization system.

La presente memoria descriptiva se refiere, a un sistema de minimización de residuos, del tipo de los utilizados durante el proceso de limpieza de prendas o artículos usados en cabinas de pintura o similar, caracterizado, porque las prendas o artículos impregnados con masillas y pastas de PVC se limpian en seco con percloroetileno, teniendo que extraer los residuos después del lavado y almacenarlos en bidones, realizándose un posterior proceso de destilación en el mismo bidón, obteniéndose percloroetileno para recircular en el proceso y residuos de masillas para gestionar, también puede depurarse el agua tras una triple decantación, a través de un filtro de carbón activado.The present specification refers to a waste minimization system, of the type used during the process of cleaning garments or items used in paint booths or similar, characterized, because the garments or Items impregnated with putties and PVC pastes are cleaned in dry with perchlorethylene, having to extract the waste after wash and store them in drums, performing a subsequent distillation process in the same drum, obtaining perchlorethylene to recirculate in the process and putty residues to manage, you can also purify the water after a triple decanting, through an activated carbon filter.

Actualmente en los departamentos o cabinas de pintura, es común la utilización de prendas de diversos tipos, monos, guantes, bayetas, etc. las cuales quedan impregnadas de masillas y pastas de PVC, siendo necesaria su limpieza, para evitar en lo posible la contaminación de los artículos fabricados.Currently in the departments or cabins of painting, the use of garments of various types is common, monkeys, gloves, cloths, etc. which are impregnated with PVC putties and pastes, cleaning being necessary, to avoid if possible the contamination of manufactured items.

La limpieza de las mencionadas prendas genera unos residuos que es necesario tratar, ya existen diferentes formas de minimizar los residuos generados por la limpieza de prendas o artículos con masillas y pastas de PVC, utilizándose durante el proceso un tipo de destilación convencional, la cual funciona mediante calor en la parte inferior del destilador, quedando la masilla pegada en la base del destilador que actúa como superficie del calor e impide la transmisión del calor al volumen total de másticos que deseamos destilar.The cleaning of the mentioned garments generates some waste that needs to be treated, there are already different ways to minimize waste generated by the cleaning of garments or articles with putties and PVC pastes, used during the process a type of conventional distillation, which works by heat at the bottom of the distiller, leaving the putty stuck on the base of the distiller that acts as a surface of heat and prevents the transmission of heat to the total volume of mastic we want to distill.

La utilización de este tipo de destilación tiene el inconveniente de que la masilla queda pegada en las paredes del destilador impidiendo su correcta destilación.The use of this type of distillation has the disadvantage that the putty is stuck on the walls of the Distiller preventing its correct distillation.

Para solventar la problemática existente en la actualidad se ha ideado un sistema de minimización de residuos, caracterizado porque después del lavado en seco de las prendas con percloroetileno, se extraen los residuos de las máquinas, consistentes en masillas mezcladas con percloroetileno, que son almacenados en bidones con una capacidad de 300 kilos.To solve the problem in the Currently, a waste minimization system has been devised, characterized in that after dry cleaning of garments with perchlorethylene, the waste from the machines is extracted, consisting of putties mixed with perchlorethylene, which are stored in drums with a capacity of 300 kilos.

Una vez almacenados se inicia el proceso de destilación, el cual se realiza en el mismo bidón, introduciendo en su interior un tubo, que llega hasta la base inferior del propio bidón, seguidamente se le inyecta vapor, proveniente de una caldera, de esta manera el calor se homogeniza en todo el volumen necesitando menor temperatura para la destilación.Once stored, the process of distillation, which is done in the same drum, introducing in inside a tube, which reaches the bottom of the base itself drum, then steam is injected from a boiler, in this way heat is homogenized throughout the volume needing a lower temperature for distillation.

Tras la destilación se extraen del bidón, las aguas de contacto, consistentes en agua con trazas de percloroetileno, y los residuos de masilla para gestionar aproximadamente 60 kilos.After distillation, they are removed from the drum, contact waters, consisting of water with traces of perchlorethylene, and putty residues to manage approximately 60 kilos

Una triple decantación y un posterior paso a través de un filtro de carbón activado nos permite separar el agua del percloroetileno, pudiéndose reutilizar éste en el proceso de limpieza.A triple settling and a subsequent step to through an activated carbon filter allows us to separate the water of perchlorethylene, which can be reused in the process of cleaning.

Este sistema de minimización de residuos que se presenta aporta múltiples ventajas sobre los sistemas empleados en la actualidad, destacando principalmente el tipo de destilación, el cual se realiza en el mismo bidón de almacenamiento de residuos.This waste minimization system that is presents brings multiple advantages over the systems used in today, mainly highlighting the type of distillation, the which is done in the same storage drum of waste.

Otra de las más importantes ventajas consiste en que se inyecta vapor en un tubo introducido en el interior del bidón, para que todo el volumen de residuos homogenice la temperatura evitando que la masilla quede pegada en las paredes del bidón.Another of the most important advantages consists in that steam is injected into a tube inserted inside the drum, so that the entire volume of waste homogenizes the temperature preventing the putty from sticking to the walls of the drum.

Otra ventaja añadida es que una vez realizada la destilación de cada bidón pueden gestionarse 60 kilos de residuo directo, y reutilizarse tanto el agua como el percloroetileno.Another added advantage is that once the Distillation of each canister can handle 60 kilos of waste direct, and reuse both water and perchlorethylene.

Para comprender mejor el objeto de la presente invención, en el plano anexo se ha representado una realización práctica preferencial de la misma. En dicho plano:To better understand the purpose of this invention, an embodiment has been shown in the attached drawing preferential practice of it. In that plane:

La figura -1- muestra un diagrama de bloques desarrollando el proceso del sistema que se presenta.Figure -1- shows a block diagram developing the system process presented.
