Abstract
The utility model relates to a falling film evaporator, including the heating chamber, be equipped with a plurality of heating pipes in the heating chamber, a plurality of heating pipes are installed on the heating pipe mounting panel, the up end of heating pipe with the up end parallel and level of heating pipe mounting panel, be equipped with liquid distributor film forming ware in the heating pipe, liquid distributor film forming ware includes a cylinder, stretch out the upper end of cylinder one section distance in upper end of heating pipe, the detachable connection of a lower extreme cone of cylinder, the bottom face of cone has the concave arc face. The utility model discloses falling film evaporator can make can be on the pipe wall of the heating pipe even cloth membrane of solution effectively, and can prevent that flash steam from directly being scurried out by the heating pipe top, has solved the inhomogeneous problem of present falling film evaporator cloth membrane.
Description
Technical field
The utility model belongs to concentration of liquid medicine processing technology field, is specifically related to a kind of falling film evaporator.
Background technology
Producing of existing powdery medicine or medicine material, general employing concentrate drying method, namely medicine stoste is first prepared, and then medicine stoste is transported to chemical liquid enrichment facility concentrates, carry out drying after concentrated again and form powdery product, and the evaporimeter under prior art has a variety of, one is wherein had to be falling film evaporator, falling film evaporation is added from falling film evaporator heating clamber upper tube box at feed liquid, through liquid distribution and film formation device, be evenly distributed in each heat exchanger tube, under gravity and vacuum induced and airflow function, uniformly membranaceously to flow from top to bottom.In flow process, heat vaporized by shell side heat medium, the steam produced and liquid phase enter the separation chamber of evaporimeter jointly, vapour-liquid is through being fully separated, steam enters condenser condenses (single-action operation) or enters lower 1st effective evaporator as heat medium, thus realizing multiple-effect operation, liquid phase is then discharged by separation chamber.
But current falling film evaporator in use there will be the uniform not problem of film forming, have impact on the effect of evaporation, is therefore necessary to be improved.
Utility model content
The purpose of this utility model is solve the problems of the technologies described above and provide a kind of falling film evaporator for concentrated medicament.
For achieving the above object, the utility model is by the following technical solutions:
A kind of falling film evaporator, comprise heating clamber, multiple heating tube is provided with in described heating clamber, described multiple heating tube is arranged on heating tube installing plate, the upper surface of described heating tube is concordant with the upper surface of described heating tube installing plate, liquid distribution film forming device is provided with in described heating tube, described liquid distribution film forming device comprises a cylinder, upper end one segment distance of described heating tube is stretched out in described cylindrical upper end, the detachable connection one in described cylindrical lower end cone, the bottom face of described cone has cancave cambered surface.
Described cylinder and described cone are threaded connection.
Described heating tube welds with described heating tube installing plate.
The utility model falling film evaporator, comprise heating clamber, multiple heating tube is provided with in described heating clamber, described multiple heating tube is arranged on heating tube installing plate, the upper surface of described heating tube is concordant with the upper surface of described heating tube installing plate, liquid distribution film forming device is provided with in described heating tube, described liquid distribution film forming device comprises a cylinder, upper end one segment distance of described heating tube is stretched out in described cylindrical upper end, the detachable connection one in described cylindrical lower end cone, the bottom face of described cone has cancave cambered surface, can effectively make solution can on the tube wall of heating tube even cloth film, and can prevent indirect steam from directly being scurried out by heating tube top, solve the problem that current falling film evaporator cloth film is uneven.
