Fire hose drying device based on solution dehumidification and exhaust gas heat recycling

Abstract

The invention discloses a fire hose drying device based on solution dehumidification and exhaust gas heat recycling. The fire hose drying device comprises a return air inlet, an air pipe, an absorbingmachine, a draught fan, an air inlet, a drying chamber, a lithium bromide dilute solution collecting machine, a solution pipe, a solution pump, a generator, a lithium bromide concentrated solution spraying nozzle, a gas fired boiler, a hot water pump, a heat recycling device, a thermometer, an electronic bypass air valve, a water pump, an exhaust gas pipe, and an exhaust gas bypass pipe. The drying chamber comprises an air inlet, a return air inlet, a fire hose inlet, a fire hose outlet, a personnel entering exiting door, and a working table.When moisture content of circulating air in the drying chamber increases, and under action of the draught fan, the circulating air enters the absorbing machine, heat-moisture exchange occurs between the circulating air and the lithium bromide concentrated solution, the circulating air is dried and heated and is secondarily heated by the heat recycling device, and enters the drying chamber through the air inlet to dry the fire hose. The problem that the fire hose cannot be dried for a short time after use is solved, maintenance of fire hoses of fire fighting companies after use is facilitated, and the service life of the fire hoses is prolonged.

Description

technical field [0001] The invention relates to a fire hose drying device based on solution dehumidification and flue gas heat recovery, which is used in the drying field of fire hose. Background technique [0002] As an important firefighting equipment tool, the fire hose is used to transport high-pressure water or foam and other flame-retardant liquids. The inside of the fire hose is rubber and the outside is nylon cloth. Due to the working environment of the fire hose, there is a lot of water on the surface of the fire hose after use. If the fire hose is not dried in time, it will easily lead to mold and rot of the hose, shorten the service life of the fire hose, and not Conducive to the normal use of fire hose. At the same time, the temperature of the hot air generated by the drying device at this stage is too high, and the rubber inside the fire hose is easily damaged due to high temperature. However, the present invention proposes a fire-fighting hose drying device ...
