Description

Variable diameter tube side heat exchanger for hot-blast stove
Technical field
The invention belongs to the technical fields of heat exchanger for hot-blast stove, more particularly to a kind of variable diameter tube side heat exchanger for hot-blast stove.
Background technique
The heating furnace of Lubricating oil refining device generally uses hot-blast stove.Hot-blast stove is that one kind loses open fire, process stream with The equipment that high-temperature flue gas improves temperature by heat exchanger heat exchange, main function are to be added the oil product for lubricating oils using high-temperature flue gas Temperature is heated to reaching certain vaporization rate.The operating condition of hot-blast stove is more special, is reached by high-temperature flue gas plus hot medium The purpose of high-temperature evaporation, but excessively high temperature easily makes medium generate Coking blocking pipeline, reduces heat exchange efficiency, increase stops Vehicle cleaning frequency.
Industrial enterprise is the pursuit always of work to continuous production, reduction repair rate, because of common hot-blast stove use etc. Diameter heat exchanger tube, thus oil product can not vaporize in heat exchanger tube, cause pressure of the lubricating oil in heat exchanger tube high, outlet temperature is high, Vaporization rate is low, and coking is serious.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of variable diameter tube side heat exchanger for hot-blast stove, reduce heat exchanger media Outlet temperature improves medium Coking, improves medium vaporization rate.
The technical solution adopted by the present invention to solve the technical problems is to provide a kind of variable diameter tube side heat exchanger for hot-blast stove, packet Bobbin carriage, several grades of heat exchanger tubes, several variable diameter connecting bends and finned tube are included, the internal diameter of heat exchanger tubes at different levels is different and is all larger than fin The internal diameter of pipe, the row that several grades of heat exchanger tubes and finned tube increase with the flow direction of internal heat medium according to internal diameter step by step Column mode is set in the chamber journey of bobbin carriage, is connected between adjacent heat exchange tubes and finned tube by the variable diameter connecting bend to match.
The heat exchanger tube at different levels and finned tube are coil arrangement, and each tube side is horizontally extending, folds along the vertical direction.
Thermometer and pressure gauge are separately installed on the heat exchanger tube at different levels and finned tube, the thermometer and pressure gauge are stretched Out outside bobbin carriage.
The heat transferring medium arrival end of the finned tube is connected with heat transferring medium inlet flange, the heat transferring medium inlet flange It is stretched out from the inside of bobbin carriage.
The heat transferring medium outlet end of the maximum heat exchanger tube of internal diameter is connected with heat transferring medium outlet(discharge) flange, and the heat transferring medium goes out Mouth flange is stretched out from the inside of bobbin carriage.
The tube side number of diameter changing of the heat exchanger for hot-blast stove is 2~4 times.
The inside of the bobbin carriage is equipped with several tube sides.
The inner wall of the bobbin carriage is equipped with the frame of refractory material filling.
Beneficial effect
First, variable diameter tube side can achieve the effect that flow directional pressure along heat transferring medium reduces step by step, so as to reality Existing heat transferring medium vapourizing temperature reduces step by step, advantageously reduces heat transferring medium in the vapourizing temperature of heat exchanger exit section, reduces and be situated between Matter output temperature, so as to reduce the load of subsequent medium treating column.
Second, heat transferring medium vapourizing temperature reduces step by step, and can be effectively improved causes to be situated between since medium vapourizing temperature is excessively high The situation of matter coking and slagging improves line clogging problem, is conducive to extend the heating furnace time between overhauls(TBO), reduces production cost.
Third, medium inlet section carry out high efficient heat exchanging using finned tube, and reduce the medium vaporization temperature of middle upper section tube side Degree is conducive to improve medium vaporization rate, improves vaporization yield.
