At the significant wastage of the energy, while it also polluted the environment of surrounding.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of tube furnace waste heat utilization device, simple and practical, section
Energy effect is good, reduces environmental pollution, convenient for monitoring and managing exhaust emissions, gas using quantity is greatly lowered, has saved production
Cost.
In order to solve the above technical problems, the technical solution of the utility model is:
A kind of tube furnace waste heat utilization device, including heat exchanger, heat exchanger be provided with hot exhaust gas import, cold offgas outlet,
Inlet of cold air and hot air outlet, hot exhaust gas import are respectively communicated with air-distillation furnace, crude naphthalene rectifying furnace, work by pipeline
Just furnace and the tail gas outlet for being evaporated under reduced pressure furnace roof portion, hot air outlet are respectively communicated with air-distillation by pipeline to industry naphthalene
The first furnace of furnace, crude naphthalene rectifying furnace, crude naphthalene and the hot-air inlets for being evaporated under reduced pressure furnace bottom, air-distillation furnace, crude naphthalene essence
Just furnace and vacuum distillation furnace bottom have also been respectively communicated with gas piping for furnace, crude naphthalene；Cold offgas outlet is connected to by pipeline
To air-distillation furnace top vent；Inlet of cold air is communicated with air blower by pipeline.
Preferably, air inducing is provided among the pipeline between the cold offgas outlet and air-distillation furnace top vent
Machine.
Preferably, the heat exchanger is tubular heat exchanger.
Preferably, just furnace and vacuum distillation furnace bottom are distinguished for the air-distillation furnace, crude naphthalene rectifying furnace, crude naphthalene
It is provided with combustion heater.
Preferably, air filter is provided in the air-distillation furnace top vent.
Preferably, exhaust emissions on-line monitoring system is provided in the air-distillation furnace top vent.
Working principle:
It will be produced in original 4 tube furnaces (the first furnace of air-distillation furnace, crude naphthalene rectifying furnace, crude naphthalene and vacuum distillation furnace)
Raw high-temperature tail gas merges, and tail gas temperature after heat exchanger exchanges heat reduces, and the exhaust of air-distillation furnace roof is evacuated to by air-introduced machine
Mouth concentrates discharge.After the preheated device of air exchanges heat with high-temperature tail gas, becomes high temperature air, then have respectively entered 4 tube furnaces
Combustion-supporting gas-fired.
By adopting the above-described technical solution, the beneficial effects of the utility model are:
1. the utility model discharges after high-temperature tail gas is exchanged heat by heat exchanger, exhaust temperature is reduced, is reduced to pipeline
The extent of damage.
2. the utility model is concentrated by atmospheric pipe still top after merging tail gas and discharged, convenient for Centralizing inspection and management tail
Gas emission behaviour.
3. the high temperature air that the utility model will generate after heat exchange, have respectively entered air-distillation furnace, crude naphthalene rectifying furnace,
Crude naphthalene just furnace and combustion-supporting gas-fired in vacuum distillation furnace, is greatly lowered gas using quantity, saves production cost.In short,
The utility model is simple and practical, energy-saving effect is good, reduces environmental pollution, convenient for monitoring and managing exhaust emissions, significantly drops
Low gas using quantity, has saved production cost.
