Abstract
The utility model discloses a device for drying materials by using the waste heat from the flue gas and tail gas of a boiler, which belongs to the field of energy-saving devices. A discharge flue of the boiler is connected at the heat supply end of a flue gas heat exchanger, and a smoke outlet of the flue gas heat exchanger is connected with a smoke exhaust fan; an air inlet of the flue gas heat exchanger is opened towards the atmosphere, a hot air outlet pipeline is divided into two ways, one pipeline is communicated with a hot air heater through a fan, an air outlet pipeline for the hot air heater is communicated with a material drying device through a fan, and the other pipeline with a gate valve is communicated with an air inlet of an air blower for a boiler combustion chamber; and a tail gas pipeline introduced out from a material steaming and frying device is connected at the heat supply end of the hot air heater and connected with a return water tank. The device for drying materials by using the waste heat from the flue gas and tail gas of the boiler is used for drying the materials by using two kinds of waste heat, further utilizes the waste heat, saves the 80 percent of drying energy resources, reduces the production cost and improves the economic benefit.
Description
1, technical field: the utility model relates to a kind of energy-saving equipment, especially a kind of residual heat using device.
2, background technology: the flue gas of boiler is generally just arranged to atmosphere after passing through to economize coal gas, heat exchanger in boiler.The steam of boiler steam to be fried tail vapour later in the workshop to material and also is put into recovery tank to become cooling water recycling.In fact flue gas that is discharged and tail vapour also have very high temperature, and its heat has wasted.Plant material is wanted heating, drying moisture earlier in process, consume the new energy, if can rationally utilize waste heat, just may save the energy, brings tangible economic benefit to enterprise.
3, summary of the invention: the purpose of this utility model is a kind of device that utilizes boiler smoke and tail vapour waste heat oven dry material of design.It can make full use of the waste heat of flue gas and tail vapour, saves the energy, reduces cost.Its technical scheme is: the smokejack of boiler connects the heat supply end of flue gas heat exchanger, and the outlet flue of flue gas heat exchanger connects smoke exhaust fan.The air inlet of flue gas heat exchanger is opened to atmosphere, the hot-blast outlet pipeline is divided into two-way, one the tunnel is communicated with storage heater through blower fan, and storage heater air-out pipeline is communicated with drying materials equipment by blower fan, and another road has the blower inlet of the pipeline connection boiler furnace of gate valve.Connect the heat supply end of storage heater from the tail gas pipe road that material steaming stir-fry equipment is drawn, tail vapour is drawn pipeline and is connected recovery tank.
Utilize the device of boiler smoke and tail vapour waste heat oven dry material to utilize two kinds of waste heat oven dry materials, made full use of used heat, thereby saved the 80% oven dry energy, reduced production cost, improved economic benefit.
4, description of drawings: Fig. 1 is the structural representation that utilizes the device of boiler smoke and tail vapour waste heat oven dry material.
5, the specific embodiment: be further described below in conjunction with accompanying drawing.As shown in Figure 1, the smokejack 5 of boiler 1 connects the heat supply end of flue gas heat exchanger 2, and the outlet flue of flue gas heat exchanger connects smoke exhaust fan 7, the flue gas row heavenwards of finishing heat exchange.The air inlet of flue gas heat exchanger is opened to atmosphere, makes inhaled air enter heat exchanger and is heated.The hot-blast outlet pipeline is divided into two-way, and one the tunnel through blower fan 6 connection storage heaters 10, and hot blast is further heated, and storage heater air-out pipeline is communicated with drying materials equipment 8 by blower fan 9, and perhaps other use hot facility, for example the warm-air drier in workshop.In the time need not drying material, allow hot blast try a different way directly.Another road has the blower inlet of the pipeline connection boiler furnace of gate valve 12.Open gate valve, hot blast enters boiler by boiler blower, helps improving temperature in the stove.The steam of boiler is mainly used to heating and steam fries material, and the material that steam pipework 3 leads to workshop 4 is heated and steamed stir-fry equipment, finishes the steam that steams the stir-fry task of heating and is called as tail vapour, and tail vapour still has the above high temperature of 100 degree, can utilize it that hot blast is heated again.The tail gas pipe road connects the heat supply end of storage heater 10, is passed through steam outlet pipe road guiding recovery tank 11 by the tail vapour after utilizing once more.The condensed water reusable edible.
Claims (1)
1. utilize the device of boiler smoke and tail vapour waste heat oven dry material, be made up of pipeline, blower fan, heat exchanger, it is characterized in that: the smokejack (5) of boiler (1) connects flue gas heat exchanger (2), and the outlet flue of flue gas heat exchanger connects smoke exhaust fan (7); The air inlet of flue gas heat exchanger is opened to atmosphere, goes out hot air duct and is divided into two-way, and one the tunnel through blower fan (6) connection storage heater 10, and the hot-blast pipe line that goes out of storage heater is communicated with drying materials equipment (8) by blower fan (9); Another road has the blower inlet of the pipeline connection boiler furnace of gate valve (12); Connect the heat supply end of storage heater (10) from the tail gas pipe road that material steaming stir-fry equipment is drawn, tail vapour steam outlet pipe road connects recovery tank (11).
