Description

Изобретение относится к охлажда^· •ющим устройствам, предназначенным на эффекте Пельтье, и может быть использовано в различных технологических процессах любой промышленности,и в чат стнбсти, для осушки воздуха в газоана-5 литических системах.The invention relates to cooling devices designed for the Peltier effect, and can be used in various technological processes of any industry, and in the chat room, for air drying in gas analysis systems.

Известны термоэлектрйческие осушители газов, содержащие теплойзолйрованную камеру, -снабженную подводящим и отводящим патрубками и заполненную ¹⁰пористым теплопроводным материалом, имеющим тепловой контакт со стенками камеры, одна из которых примыкает к холодным спаям термоэлектрической батареи II) .Known thermoelectric gas dehumidifiers containing a heat-insulated chamber, equipped with inlet and outlet pipes and filled with ¹⁰ porous heat-conducting material having thermal contact with the walls of the chamber, one of which is adjacent to the cold junctions of the thermoelectric battery II).

Недостаток известного осушителя заключается в том, что в нем в теплоизолированной камере находятся как поток газа, подвергаемый осушению, так и поток ух:е осушенного газа, что не позволяет устанавливать его вертикально и. размещать подводящий и отводящий патрубки в одной плоскости, поскольку ухудшается отвод осушенного газа и снижается степень осушки последнего.A disadvantage of the known dehumidifier is that in it in the heat-insulated chamber there are both a gas stream to be dried and a gas stream: dried gas, which does not allow it to be installed vertically and. place the inlet and outlet pipes in the same plane, since the drainage of the dried gas deteriorates and the degree of drying of the latter decreases.

Цель изобретения - повышение эффективности осушителя при его вертикальном размещении путем улучшения отвода газа и повышения степени его осушки.The purpose of the invention is to increase the efficiency of the desiccant in its vertical placement by improving the removal of gas and increasing the degree of drying.

Цель достигается тем, что в известном термоэлектрическом осушителе газов, содержащем теплоизолированную камеру, снабженную подводящим и отводящим патрубками и заполненную пористым теплопроводным материалом, имеющим тепловой контакт со стенками камеры, одна из которых примыкает к холодным спаям термоэлектрической батарей, она снабжена вертикальной газоотводящей трубкой, установленной внутри камеры с зазором относительно ее стенки, пришкаккцей к холодным спаям, и с образованием теплового контакта с пористым материалом.The goal is achieved by the fact that in the known thermoelectric gas dryer containing a thermally insulated chamber, equipped with inlet and outlet pipes and filled with porous heat-conducting material having thermal contact with the walls of the chamber, one of which is adjacent to cold junctions of thermoelectric batteries, it is equipped with a vertical gas outlet pipe installed inside the chamber with a gap relative to its wall, attached to cold junctions, and with the formation of thermal contact with the porous material.

Осушитель содержит теплоизолированную камеру 1, подводящий патрубок 2, отводящий патрубок 3, пористый теплопроводный материал 4, термоэлектрическую батарею 5 с холодными спаями $ и горячими спаями 7, вертикальную газоотводящую трубку 8, радиаторы 9 и 10, конденсатосборник 11, снабженный сливным патрубком I2 и соединенный с камерой 1 с помощью отверстия 13, и 10 теплоизоляцию 14.The dryer contains a thermally insulated chamber 1, a supply pipe 2, a discharge pipe 3, a porous heat-conducting material 4, a thermoelectric battery 5 with cold junctions $ and hot junctions 7, a vertical gas outlet tube 8, radiators 9 and 10, a condensate collector 11, equipped with a drain pipe I2 and connected with the camera 1 using the holes 13, and 10 thermal insulation 14.

Осушитель работает следующим образом.Dehumidifier works as follows.

Горячий газ поступает в охлаждае- 1S мую камеру 1 через патрубок 2, в которой циркулирует сверху вниз. В процессе циркуляции температура газа снижается ниже точки росы, и из газа выпадает конденсат, поступающий через эд отверстие 13 в конденсатосборник 11, откуда удаляется через патрубок 12. Осушенный и охлажденный газ поступает в трубку 8 и удаляется через патрубокHot gas enters the cooled 1S chamber 1 through the pipe 2, in which it circulates from top to bottom. In the process of circulation, the gas temperature drops below the dew point, and condensate drops out of the gas through the ed hole 13 into the condensate collector 11, from where it is removed through the pipe 12. The dried and cooled gas enters the pipe 8 and is removed through the pipe

3. Установка в теплопроводном матери- эд але, которым заполнена камера вертикальной трубки, позволяет разделить потоки газов (горячего и холодного), а также повысить холодопроизводитель ность осушителя и снизить расход электроэнергии на питание термобатареи.3. Installation in a heat-conducting material, with which the vertical tube chamber is filled, allows to separate the gas flows (hot and cold), as well as increase the cooling capacity of the dryer and reduce the energy consumption for powering the thermopile.

Claims

The invention relates to cooling devices designed for the Peltier effect, and can be used in various technological processes of any industrial scale, and are designed for drying air in gas ventilation systems. Thermoelectric gas dryers are known that contain a heat-insulated chamber, equipped with inlet and outlet pipes and filled with a porous heat-conducting material, having thermal contact with the walls of the chamber, one of which is adjacent to the cold slots of the thermoelectric battery. A disadvantage of the known dehumidifier is that both the gas stream undergoing drying and the flow of yy: e of the dried gas are present in the heat insulating chamber, which does not allow its vertical positioning. place the inlet and outlet nozzles in one area, since the discharge of dried gas is deteriorated and the degree of drying of the latter is reduced. The purpose of the invention is to increase the efficiency of the dehumidifier when it is placed vertically by improving the gas outlet and increasing the degree of its drying. The goal is achieved by the fact that in a known thermoelectric gas dryer containing a thermally insulated chamber equipped with inlet and outlet pipes and filled with a porous thermally conductive material having thermal contact with the chamber walls, one of which is adjacent to the cold spans of the thermoelectric battery, it is equipped with a vertical gas outlet a tube installed inside the chamber with a gap relative to its wall, approaching cold spas, and with the formation of thermal contact with the porous material. On 4ig. I depicts the proposed dryer, incision; in fig. 2 shows section A-A in FIG. 1. 388 The dryer contains a heat-insulated chamber 1, a supply nozzle 2, a discharge nozzle 3, a porous heat-conducting material 4, a thermoelectric battery 5 with cold joints 6 and hot joints 7, a vertical vapor tube 8, radiators 9 and 10 , a condensate trap 11, provided with a drain pipe 12 and connected to the chamber 1 by means of an aperture 13, and heat insulation 14. The desiccant works as follows. The hot gas enters the cooled chamber 1 through the nozzle 2, in which it circulates from top to bottom. During the circulation, the gas temperature decreases below the dew point and condensate escapes from the gas, entering through the gas condensate collector I through the port 13, from where it is removed through the nozzle 12. The dried and cooled gas enters the tube 8 and is removed through the nozzle 3. the thermally conductive material with which the vertical tube chamber is filled allows to separate the gas flows (hot and cold), as well as to increase the refrigerating capacity of the dehumidifier and to reduce the electric power consumption for the thermopile power supply. A thermoelectric gas dryer containing a thermally insulated chamber, equipped with inlet and outlet pipes and filled with a porous heat-conducting material, has thermal contact with the walls of the chamber, one of which is adjacent to cold spans of a thermoelectric battery, characterized in that, in order to increase efficiency by improving the gas outlet and increasing the degree of its drying when the dryer is placed vertically, it is equipped with a vertical gas outlet tube installed inside the chambers monitors with a gap relative to its wall adjacent to the cold junctions, and with the formation of thermal contact with the porous material.
