Description
Technical field
The utility model relates to the heat recovery technology field, particularly a kind of remote flue gas waste heat recovery apparatus.
Background technology
In large size industrial enterprise, a lot of equipment all can produce a large amount of waste heats, if these waste heats are not recycled, have then wasted.Such as steel mill, chemical plant, the high-temperature flue gas flue that the high-altitude is laid is rich in waste heat, present enterprise more than 90% discharges with the cooling of cold water spray again, not only effectively do not utilize the waste heat in the high-temperature flue gas flue, but also wasted a large amount of cooling waters, this has just caused dual energy waste.
Also have some enterprises to adopt separate unit heat pipe energy-saving equipment to carry out heat recovery at present, but this equipment can not be carried at a distance.When UTILIZATION OF VESIDUAL HEAT IN equipment and heat resource equipment distance is far away, the occasion of gas-gas heat exchange especially, separate unit heat pipe energy-saving equipment is just powerless.
Summary of the invention
The technical problems to be solved in the utility model is, high-temperature flue gas waste heat in a kind of can conveniently the recovery is provided, and the remote flue gas waste heat recovery apparatus of high-temperature flue gas waste heat in utilizing at a distance.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: remote flue gas waste heat recovery apparatus, comprise the high-temperature flue gas pipeline, it is characterized in that: also comprise thermal source heat exchange of heat pipe, low-temperature receiver heat exchange of heat pipe and kinetic pump, the thermal source heat exchange of heat pipe is installed on the high-temperature flue gas pipeline, the thermal source heat exchange of heat pipe is connected by circulating line with the low-temperature receiver heat exchange of heat pipe, fill heat transferring medium in the circulating line, kinetic pump is arranged on the circulating line, and the low-temperature receiver heat exchange of heat pipe connects UTILIZATION OF VESIDUAL HEAT IN equipment.
Also be provided with temperature-detecting device on the described circulating line, this temperature-detecting device connects kinetic pump by controller.
Described heat transferring medium is a hydrogenated terphenyl.Lower, the non-corrosiveness of heat transferring medium saturated pressure, stable not perishable, dynamic viscosity is low, specific heat capacity and thermal conductivity coefficient height, the adaptive temperature scope is wider.
The thermal source heat exchange of heat pipe is installed in the waste heat that reclaims on the high-temperature flue gas pipeline in the high-temperature flue gas, and waste heat is stored in the heat transferring medium, improves the temperature of heat transferring medium in the thermal source heat exchange of heat pipe.Thermal source heat exchange of heat pipe output high temperature heat transferring medium, the high temperature heat transferring medium enters the low-temperature receiver heat exchange of heat pipe by circulating line under the effect of kinetic pump, the low-temperature receiver heat exchange of heat pipe is used the heat transferred UTILIZATION OF VESIDUAL HEAT IN equipment in the high temperature heat transferring medium, thereby realizes the recovery and remote utilization of high-temperature flue gas waste heat.
Be arranged on the temperature that temperature-detecting device on the circulating line detects heat transferring medium in the circulating line, and this temperature signal is passed to controller, controller analysis temperature signal is also controlled the operation of kinetic pump.When detected temperatures reached design temperature, controller started kinetic pump; When detected temperatures was lower than design temperature, controller cut out kinetic pump.
Heat transferring medium in circulating line, low-temperature receiver heat exchange of heat pipe and the thermal source heat exchange of heat pipe makes remote flue gas waste heat recovery apparatus stable, efficient.
In sum, the beneficial effects of the utility model are: reclaim fume afterheat efficient height, can utilize the waste heat of recovery at a distance, and can realize control automatically by the cooperation of temperature-detecting device and controller.
