Description
Technical field
The utility model relate to a kind of purify chemical products time the heat exchanger that uses, the hot water circulation bucket specifically used in a kind of refined naphthalene production process.
Background technology
Refined naphthalene to be purified further the obtained naphthalene product being not less than 79.3 DEG C containing naphthalene more than 98.45%, ctystallizing point by NAPTHALENE FLAKES. (INDUSTRIAL GRADE）.Refined naphthalene is for the manufacture of pigment dyestuff intermediate, mothball, leather and Wood protecting agent etc.Naphthane, benzo-thiophene, xylenol etc. that impurity in NAPTHALENE FLAKES. (INDUSTRIAL GRADE） is mainly more close with naphthalene boiling point, as the boiling point (218 DEG C) of naphthalene differs less than 2 DEG C with the boiling point (219.9 DEG C) of benzo-thiophene.Therefore, in order to manufacture the higher refined naphthalene of purity, utilizing the naphthalene physical properties different from these impurity fusing points to be separated with regard to needing, or utilizing chemical process to change their chemical constitution.
The production method of current refined naphthalene mainly contains crystallization process, hydrofining method, pickling distillation method, subliming method etc.Crystallization process naphthalene process for refining is with technical process and equip simple, and processing method is ripe, the advantages such as energy consumption is less, good product quality, is known as advanced naphthalene purification techniques both at home and abroad.Described crystallization process prepares refined naphthalene, and namely NAPTHALENE FLAKES. (INDUSTRIAL GRADE） is purified through " crystallization-thawing " process, and because the impurity ctystallizing point in material is lower, impurity stays in the liquid phase and is removed in the process.
And originally to prepare the heat exchanger that refined naphthalene uses be hot water tank, be the heating coil indirect heating of being installed by hot water tank inwall to hot water tank heating, indirect heating shortcoming is that heat-transfer effect is poor, and steam condensate is arranged outward and caused thermo-efficiency low; Cooling is then undertaken by external cooler, indirectly cools and also there is the problem of heat-transfer effect difference, energy dissipation.
Summary of the invention
The purpose of this utility model is to provide the hot water circulation bucket of a kind of direct intensification and cooling, and the cooling that heats up has been come by a device, improves warming and cooling rate, save energy.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of hot water circulation bucket produced for refined naphthalene, comprise staving, base and cover plate, at staving sidewall, the position of base is provided with circulating water outlet, on the cover board be provided with circulating water intake, enter steam port, enter cooling nozzle and refluxing opening, described enter steam port place be provided with access tube, access tube end is inserted in staving.
Described hot water circulation bucket is linked into naphthalene crystal room, forms heat exchange system, by regulating the temperature carrying out controlled circulation medium into steam port, the valve that enters cooling nozzle and refluxing opening.
The beneficial effects of the utility model are: the utility model adopts a device to complete and directly heats up and directly cooling, and structure is simple, effectively can improve thermo-efficiency, reduces energy loss.
