Abstract
The invention relates to a continuous gas sample extraction system for industrial applications with gas sample temperatures of up to 1500° Kelvin as is typical in rotary kilns in the cement industry and similar applications. The purpose of the invention is to reduce possible condensation and interaction between the gaseous parts, by providing a system that maintains a homogeneous temperature, which is greater than critical dew-point temperatures, from the tip of the sampling tube (6) to the connection point of the heated hose (13). This objective is achieved by integrating all of the necessary critical mechanical elements inside the container used for the recirculation of the heat-transfer liquid and exposing said elements (e.g. valves, filter elements, a recirculation pump, among others) to the same temperature as the heat-transfer liquid. The compressed gas safety device (1) forms part of the basic support structure, thereby ensuring the permanent availability of compressed gas, which is required by design for the extraction of the sensor by means of a pneumatic motor, and the flushing of the sampling tube (6) and the filter element (5).

DESCRIPCIÓN DETALLADA DE LA INVENCIÓNDETAILED DESCRIPTION OF THE INVENTION
En aplicaciones en la industria metalúrgica, cementera, vidrio y similares se requiere la extracción de muestras de gas representativas del proceso en forma continua con la finalidad de poder obtener información de la concentración de sus componentes gaseosos, para poder
controlar y optimizar el proceso y/o para fines de control ambiental. Para proteger el tubo de extracción de muestras de gas de la alta temperatura de los gases de proceso - que puedan alcanzar hasta 1500 grados Kelvin - y reducir la posible condensación y reacción química de algunos de los componentes gaseosos extraídos - como vapor de agua, bióxido de azufre, monóxido de carbono y bióxido de nitrógeno entre otros - se requiere la termostatización de todos los componentes mecánicos involucrados a temperaturas superiores al punto critico de rocío - pero siempre mas alta que la temperatura de ebullición del agua a nivel del mar - en especial del TUBO DE MUESTREO (6), de las VÁLVULAS DE CONTROL (9), de la BOMBA DE RECIRCULACIÓN SUMERGIDA (10), del ELEMENTO FILTRANTE (5) y de los TUBOS PARA PRECALENTAR EL GAS COMPRIMIDO DE PURGA (11).In applications in the metallurgical, cement, glass and similar industries, the extraction of gas samples representative of the process is required continuously in order to obtain information on the concentration of its gaseous components, in order to control and optimize the process and / or for environmental control purposes. To protect the gas sampling tube from the high temperature of the process gases - which can reach up to 1500 degrees Kelvin - and reduce the possible condensation and chemical reaction of some of the gaseous components extracted - such as water vapor, dioxide of sulfur, carbon monoxide and nitrogen dioxide among others - thermostatization of all the mechanical components involved is required at temperatures above the critical dew point - but always higher than the boiling temperature of water at sea level - especially of the SAMPLING TUBE (6), of the CONTROL VALVES (9), of the SUBMERGED RECYCLING PUMP (10), of the FILTERING ELEMENT (5) and of the PIPES TO PREVENT THE COMPRESSED GAS OF PURGE (11).
Se logra este objetivo al integrar todos los componentes mecánicos antes mencionados en un CARRO MÓVIL montado en la estructura básica: El CARRO MÓVIL (2) contiene el DEPOSITO DE LIQUIDO DE TRANSFERENCIA (4), la BOMBA DE RECIRCULACIÓN SUMERGIDA (10), el INTERCAMBIADOR DE CALOR (3) con enfriamiento posible por aire ó líquido, las VÁLVULAS DE CONTROL (9) de succión y purga, el ELEMENTO FILTRANTE (5) para la separación del polvo y los TUBOS PARA PRECALENTAR EL GAS COMPRIMIDO DE PURGA (11) para alimentar la purga de la sonda y limpieza del elemento filtrante y la CONEXIÓN DE MANGUERA CALENTADA (13), que transportará la muestra extraída hacia el sistema de medición de los componentes (Analizador de Gas). Todos los elementos antes mencionados son calentados por el mismo líquido de transferencia de calor una vez introducido el TUBO DE MUESTREO (6) al compartimiento previsto para este fin o por medio de algún otro dispositivo de calentamiento con energía proveniente de Energía eléctrica o vapor. Esta construcción evita la posibilidad
de un "PUENTE FRIÓ" que pudiera provocar la condensación y reacción de los componentes gaseosos extraídos.This objective is achieved by integrating all the aforementioned mechanical components into a MOBILE CART mounted on the basic structure: The MOBILE CAR (2) contains the TRANSFER LIQUID TANK (4), the SUBMERGED RECYCLING PUMP (10), the EXCHANGER OF HEAT (3) with possible cooling by air or liquid, the CONTROL VALVES (9) of suction and purge, the FILTERING ELEMENT (5) for the separation of the dust and the PIPES TO PREVENT THE COMPRESSED GAS OF PURGE (11) for feed the probe purge and clean the filter element and the HEATED HOSE CONNECTION (13), which will transport the extracted sample to the component measurement system (Gas Analyzer). All the aforementioned elements are heated by the same heat transfer liquid once the SAMPLING TUBE (6) has been introduced into the compartment provided for this purpose or by means of some other heating device with energy coming from Electricity or steam. This construction avoids the possibility of a "COLD BRIDGE" that could cause condensation and reaction of the extracted gaseous components.
El dispositivo de extracción de gas de muestra es controlado por un SISTEMA ELECTRÓNICO DE CONTROL INTELIGENTE (14) que detecta el nivel de temperatura del líquido de transferencia de calor y permite la succión y transporte del gas de muestra no antes de haber alcanzado la temperatura predeterminada, que será mas alta que la temperatura de ebullición del agua a nivel del mar. Al mismo tiempo se vigilan diferentes parámetros físicos críticos, como - por ejemplo - posición física del CARRO MÓVIL (2), presión del gas comprimido en el DEPOSITO DE SEGURIDAD DE GAS COMPRIMIDO (1), temperatura del Kquido de transferencia de calor entre otros, que en caso de ser alcanzados valores limites preestablecidos provocarán el movimiento del CARRO MÓVIL (2) para extraer el TUBO DE MUESTREO (6) del compartimiento de toma de muestra, por medio de MOTOR ELÉCTRICO, NEUMÁTICO ó HIDRÁULICO (7), según diseño específico aplicable. En caso de falla de energía eléctrica el CARRO MÓVIL (2) se extrae por medio de MOTOR NEUMÁTICO ó HIDRÁULICO (7). El DEPOSITO DE SEGURIDAD DE GAS COMPRIMIDO (1) esta formado por un tubo redondo ó de cualquier otra geometría, que forma parte integral de la estructura básica. La integración del DEPOSITO DE SEGURIDAD DE GAS COMPRIMIDO (1) a la estructura básica asegura la disponibilidad de gas comprimido requerido para la posibilidad de alimentar el dispositivo extractor con el gas comprimido, en forma permanente y con el caudal adecuado.
The sample gas extraction device is controlled by an INTELLIGENT ELECTRONIC CONTROL SYSTEM (14) that detects the temperature level of the heat transfer liquid and allows the suction and transport of the sample gas not before having reached the predetermined temperature , which will be higher than the boiling temperature of water at sea level. At the same time, different critical physical parameters are monitored, such as - for example - physical position of the MOBILE CAR (2), compressed gas pressure in the COMPRESSED GAS SECURITY DEPOSIT (1), heat transfer fluid temperature among others, that if preset limit values are reached, they will cause the movement of the MOBILE CAR (2) to extract the SAMPLING TUBE (6) from the sampling compartment, by means of ELECTRIC, PNEUMATIC or HYDRAULIC MOTOR (7), according to specific design applicable. In the event of a power failure, the MOBILE CAR (2) is removed by means of a PNEUMATIC or HYDRAULIC MOTOR (7). The COMPRESSED GAS SECURITY DEPOSIT (1) is formed by a round tube or any other geometry, which is an integral part of the basic structure. The integration of the COMPRESSED GAS SECURITY DEPOSIT (1) into the basic structure ensures the availability of compressed gas required for the possibility of feeding the extractor device with the compressed gas, permanently and with the adequate flow.
