[summary of the invention]
The object of this invention is to provide a kind of safe and reliable, energy-conservation economical, simple and convenient, saving of work and time is effective, particularly can be for the coal safety and energy-saving air-heater of inflammable and explosive industry.
Coal safety and energy-saving air-heater of the present invention, by heat-collecting box, coal furnace, heat conduction filter, heatproof blower fan, coal-fired air blast, overtemperature protection air door and temperature protection controller form, and coal furnace is positioned at heat-collecting box lower lumen, heat conduction filter is located at the inner chamber of heat-collecting box middle and upper part, heatproof fan induced draught mouth is communicated with inner chamber more than heat conduction filter in heat-collecting box, coal-fired blower outlet communicates with coal furnace, the work of coal-fired air blast can promote burning of coal, overtemperature protection exhaust door is communicated with heat-collecting box top inner chamber, temperature protection controller is responded to the temperature of heat-collecting box inner chamber and is controlled the work of coal-fired air blast, thereby the burning that realizes control coal furnace reaches the object of temperature control and protection.Coal furnace comprises burner hearth, supplying air bin and door, connection and locking device, air intake vent and running gear, and burner hearth is positioned at the top of supplying air bin, door connects with supplying air bin with coupling arrangement, locking device cuts out and fastening, air intake vent is located on supplying air bin, communicate with coal-fired blower outlet outward, running gear is located at the bottom of coal furnace, and pig iron monoblock cast be made or be used to burner hearth can with refractory brick and metal material, heat-collecting box comprises casing, visit, Xiamen, connect and locking device, air inlet, air outlet, heat conduction filter bracing or strutting arrangement, coal-fired air blast air intake vent, overtemperature protection exhaust door connector and heat-barrier material, and visit and connect with casing with coupling arrangement with Xiamen, locking device cuts out and fastening, air inlet is communicated with cabinets cavity, air outlet is communicated with inner chamber more than heat conduction filter in casing, connect with centrifugal blower inlet scoop outward, heat conduction filter bracing or strutting arrangement is located at the middle and upper part of casing, in overtemperature protection exhaust door connector, be communicated with casing top inner chamber, connect with overtemperature protection exhaust door outward, heat-barrier material is installed on casing and door, heat-collecting box comprises monoblock type and split type, heat conduction filter comprises filtering material and fixed frame, and can put down easily on the bracing or strutting arrangement that is placed on heat conduction filter, overtemperature protection exhaust door comprises exhaust outlet and air door, and air door is fixed on exhaust outlet with hinge, and during the work of heatproof blower fan, air door is closed automatically, after shutdown, automatically opens, if the running gear of coal furnace is rail wheel, in the bottom of heat-collecting box, need to add walking track.
It should be noted that, when this device is used for material drying, in drying room, have the cooperation of the servicing units such as temperature control, hydrofuge, warning; If for inflammable and explosive industry, also need the guarantee of multinomial safe practice.
The operation principle of coal safety and energy-saving air-heater of the present invention: the coal combustion in coal stove produces heat, coal-fired air blast provides needed oxygen for burning of coal, the hot gas that coal stove produces rises and after heat conduction filter filters, enters into the inner chamber on heat-collecting box top, and clean safety becomes after the spark in hot gas and dust are isolated.The work of heatproof blower fan simultaneously, first air is drawn into heat-collecting box inner chamber and mixes intensification with the coal-fired hot gas producing, then through heatproof blower fan, accelerate pressurization, the hot-air accelerating after pressurization is sent barn to through air supply duct, the repetition of above process, rises the temperature in barn.When the temperature in barn rises to the operating temperature setting, the temperature control equipment in barn sends signal, and coal-fired air blast quits work, coal furnace stops the supply of oxygen, and burning of coal weakens, and the heat of generation reduces, air heating effect weakens, temperature in barn declines, and when the temperature in barn drops to lower than the operating temperature setting, temperature controller makes again coal-fired air blast work, coal stove burning becomes prosperous, heat increases, the air grow of heating, and the temperature in barn rises again.So move in circles, make the temperature in barn keep certain.In addition; set temperature protection controller in heat-collecting box; can guarantee that heat-collecting box can superelevation in the temperature in when work; its principle is that the temperature in heat-collecting box is while reaching the protection temperature setting; temperature protection controller quits work coal-fired air blast, and coal furnace oxygen-supplying amount reduces, and burning dies down; temperature in heat-collecting box reduces, thereby can not allow temperature superelevation in heat-collecting box and be damaged.In order to ensure heat-collecting box, heat up after can the shutdown of Yin Naiwen blower fan besides too high and damaged, on heat-collecting box, be provided with overtemperature protection exhaust door.Operation principle is that overtemperature protection exhaust door is closed automatically when air-heater is normally worked, and after heatproof fan parking, air door is opened automatically, and the hot gas in heat-collecting box is discharged from overtemperature protection exhaust door, and the heat in heat-collecting box can not be assembled and cause excess Temperature.
It is very simple that this device is realized energy-conservation reason, and the one, the coal-fired heat producing is directly sent to barn, and heat energy does not need multiple conversions, and the thermal efficiency improves; The 2nd, when dry for non-inflammable and explosive material, can adopt the mode of circular heating, cold air can not enter, and hot gas can not run off.Add the utilization of scientific and reasonable working method and hydrofuge measure, can allow dry effect, energy consumption accomplish the best.
This device is accomplished safe measure, mainly the hot gas that burning produces, filtration through heat conduction filter, in hot gas, do not contain spark, there is not the hidden danger of lighting and igniting inflammable and explosive material, add that in addition the accurate control of operating temperature, remote hot gas are carried and remote work is controlled, thereby can guarantee that safety is perfectly safe.
Need to supplement a bit, produce too much flue gas when reducing fire coal, this air-heater is only suitable for burning smokeless honeycomb briquette or smokeless loose coal, forbids to burn bituminous coal or faggot.
