The industrial furnace air flue waste heat recovery system is characterized in that the heat-exchange coil (3) is fixed in the air flue, the water pump (7) is fixed between a water outlet of the water tank (6) and a water inlet of the heat-exchange coil (3), and the electromagnetic valve (5) is fixed between a water outlet of the heat-exchange coil (3) and a water inlet of the water tank (6). The industrial furnace air flue waste heat recovery system has the advantages that the system structure is simplified, space is saved, utilization costs of waste heat per unit in an industrial furnace are saved, meanwhile, hot water obtained after heat exchange can be directly used, and moreover, heat energy can be transmitted by other heat exchange modes.
Description
Technical field
The utility model relates to a kind of heat energy utilization, particularly a kind of residual neat recovering system for industrial furnace air channel.
Background technology
Industrial furnace is in industrial production, utilizes the heat of fuel combustion or electric energy conversion, by the Thermal Equipment of material or workpiece heating.Can be divided into gas furnace, coal furnace, resistance furnace etc., industrial furnace in use produces a large amount of tail gas, and general exhaust temperature is higher, if directly exhaust emissions in atmosphere, do not meet the requirement of country for energy-conserving and environment-protective, therefore how for the waste heat producing in industrial processes, to the deep utilization of carrying out of heat resource, there is important meaning for country and enterprise.The mode of UTILIZATION OF VESIDUAL HEAT IN is varied both at home and abroad at present, but due to waste heat utilization equipment more complicated, plant maintenance and running expense are higher, the problems such as organic efficiency is low, particularly for the UTILIZATION OF VESIDUAL HEAT IN of general mediumand smallscale industrial boilers, how to develop UTILIZATION OF VESIDUAL HEAT IN efficiency waste heat utilization equipment high, simple in structure and seem particularly important again.
Summary of the invention
For above problem, the purpose of this utility model is to provide a kind of industrial furnace air channel residual neat recovering system, and by being arranged in the annular heat exchange tube road on air channel, in solenoid control heat exchange pipeline, water velocity and size, shift heat energy, and its heat exchange efficiency is high.
The technical solution of the utility model is achieved in the following ways: a kind of industrial furnace air channel residual neat recovering system, by air channel, high temperature insulating material, heat exchange coil, thermoinduction probe, magnetic valve, water tank, water pump and electrical system composition, air channel inwall is provided with annular high temperature insulating material, thermoinduction probe is fixed in air channel, described heat exchange coil, magnetic valve, water tank, water pump forms a set of circulatory system, it is characterized in that: described heat exchange coil is fixed in air channel, water pump is fixed between water outlet of water tank and heat exchange coil water inlet, magnetic valve is fixed between heat exchange coil delivery port and water tank inlet.
Described heat exchange coil curl, the flue gas opposite direction in water (flow) direction and air channel in heat exchange coil.
Described thermoinduction probe is connected with electrical system, and magnetic valve is connected with electrical system, the input signal that electrical system is popped one's head in by thermoinduction, the switch size of control magnetic valve.
Described residual neat recovering system is middle and small burn coal boiler, gas fired-boiler, oil burning boiler.
The utility model, has simplified system architecture, has saved space, has saved the cost of industrial furnace applying unit UTILIZATION OF VESIDUAL HEAT IN, and the hot water obtaining after heat exchange simultaneously not only can directly use, and also can pass through other heat exchange modes, and heat energy is shifted.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1 air channel, 2 high temperature insulating materials, 3 heat exchange coils, 4 thermoinduction probes, 5 magnetic valves, 6 water tanks, 7 water pumps.
Detailed description of the invention
Known by Fig. 1, a kind of industrial furnace air channel residual neat recovering system, by air channel 1, high temperature insulating material 2, heat exchange coil 3, thermoinduction probe 4, magnetic valve 5, water tank 6, water pump 7 forms, the inwall in air channel 1 is provided with annular high temperature insulating material 2, thermoinduction probe 4 is fixed in air channel 1, water tank 6 is arranged on outside pipeline, heat exchange coil 3 is fixed in air channel 1, water pump 7 is fixed between water tank 6 delivery ports and heat exchange coil 3 water inlets, magnetic valve 5 is fixed between heat exchange coil delivery port and water tank 6 water inlets, heat exchange coil 3, magnetic valve 5, water tank 6, water pump 7 forms a set of water circulation system, heat exchange coil 3 curls, flue gas opposite direction in water (flow) direction in heat exchange coil 3 and air channel 1, high-temperature flue gas flows toward the left side from the right in air channel 1, water flows from left to right in heat exchange coil 3, 4 pairs of thermoinduction probes are surveyed by the flue-gas temperature after heat exchange coil 3 heat exchange, and the data feedback of surveying is arrived to electric control system, electric control system is controlled magnetic valve 5 according to the data of thermoinduction probe 4 feedbacks, when exhaust gas temperature higher than set value time, magnetic valve 5 increases flow, in the time that temperature is reduced to setting value, magnetic valve 5 reduces flow, ensure exhaust gas temperature dynamic equilibrium.
