Description
Technical field
The utility model relates to the NAPTHALENE FLAKES. (INDUSTRIAL GRADE） production unit, relates in particular to a kind of NAPTHALENE FLAKES. (INDUSTRIAL GRADE） single-furnace double-tower device.
Background technology
At present domestic industry naphthalene device is the twin furnace double tower process, and the cooling of partial material is by interchanger recirculated water heat exchange, its complex structure, makes and requires highly, and fuel consumption greatly in use, quantity of circulating water and a water magnitude of recruitment be large; Therefore, day by day emphasizing energy-saving and emission-reduction, water-saving today, the shortcoming of its high energy consumption, high water consumption does not meet the requirement of Sustainable development, such production technique has also increased production cost, reduces the production quality of naphthalene, has therefore also hindered the development of enterprise, along with the innovation of technology, in the urgent need to a kind of NAPTHALENE FLAKES. (INDUSTRIAL GRADE） production equipment that can reduce the novel environment friendly of energy consumption and water.
Summary of the invention
The purpose of this utility model is to provide a kind of NAPTHALENE FLAKES. (INDUSTRIAL GRADE） single-furnace double-tower device, and it has advantages of simple in structure, energy-conserving and environment-protective.
The utility model is achieved like this, it comprises primary tower, interchanger, tube furnace, rectifying tower, the stock oil oil inlet pipe, the stock oil oil outlet pipe, the naphthalene vapour-discharge tube, the washing oil oil outlet pipe, naphthalene steam inlet duct and washing oil oil inlet pipe, it is characterized in that being connected with between primary tower and the interchanger stock oil oil outlet pipe, stock oil oil inlet pipe one end links to each other with interchanger, interchanger links to each other by the washing oil oil outlet pipe with rectifying tower, one end of naphthalene vapour-discharge tube is connected to the top of rectifying tower, the other end links to each other with interchanger, interchanger also is connected with the naphthalene vapour-discharge tube, is connected with washing oil oil outlet pipe and washing oil oil inlet pipe between tube furnace and the rectifying tower.
Technique effect of the present utility model is: the required heat energy of primary tower of the present utility model is provided by rectifying tower, primary tower then provides heat-eliminating medium for rectifying tower, NAPTHALENE FLAKES. (INDUSTRIAL GRADE） single-furnace double-tower technique, only need a tube furnace, by interchanger heat is utilized mutually, also saved recirculated water and a water when greatly reducing heat energy consumption, reduced production cost, save the energy and water, had good economic benefit and environmental benefit.
