Abstract
The utility model relates to a jacketed type grading heating device, which comprises an upper jacket, a lower jacket, a traverse baffle, a valve and a pipeline connecting device, wherein through controlling the opening and closing state of the valve, the heating modes of the lower jacket and the upper jacket, which comprise single heating, series heating and parallel heating can be controlled, thereby being capable of effectively controlling the wave range of the materiel temperature in a reactor, leading the distribution of the molecular weight of products to be more uniform, and meeting the requirements of production technology of special products.
Description
Technical field
The utility model relates to a kind of still heater, particularly a kind of jacket type classification heater.
Background technology
Reactor is an equipment commonly used in the Chemical Manufacture, be widely used in oil, chemical industry, rubber, agricultural chemicals, fuel, medicine, food, be used for finishing the pressure vessel of technical process such as sulfuration, nitrated, hydrogenation, polymerization, condensation, common heater is to be provided with clamping device outside still, on chuck, be provided with inlet tube and outlet, chuck is led to into thermal medium, to material heating in the still.This mode of heating is not suitable for applying to the variation of material in the still and temperature fluctuation range is big and the big occasion of reactor draw ratio.When reaction mass is less, also can cause the waste of heat energy, can't satisfy the manufacturing technique requirent of specialities.
Summary of the invention
The purpose of this utility model provides a kind of jacket type graded supply device, can be according to the size of what and temperature fluctuation range of material, selection graded supply mode.
The technical solution adopted in the utility model is with the conventional jacket of still exogenesis up/down perforation, to be divided into chuck and last chuck two parts down, and to be provided with deflection plate to increase heat-transfer effect in chuck; Deflection plate has alternating expression and spiral two kinds of kenels; Be equipped with valve and assembling pipe joint again, the device of the mode of heating in parallel of chuck and last chuck, series connection mode of heating and independent mode of heating under constituting.
The advantage of the utility model jacket type grading plant is: the fluctuation range of having controlled the interior temperature of charge of still has effectively increased heat-transfer effect again and has saved the energy, the more important thing is that to make product molecular weight distribution more even, satisfied the manufacturing technique requirent of specialities, guaranteed the quality of product, it is minimum to allow heat energy loss drop to as far as possible when material is few, this kind energy saver suitable for large-scale promotion.
Description of drawings
Fig. 1 is a front view sketch of the present utility model
Fig. 2 is a piping diagram sketch of the present utility model
The accompanying drawing member comprises: go up chuck 1, following chuck 2, deflection plate 3, inlet tube 4, outlet 5, heating agent house steward 6, heating agent delivery pipe 7, valve 8.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Jacket type heater of the present utility model is comprised by the heating agent house steward: go up chuck 1, following chuck 2, deflection plate 3, inlet tube 4, outlet 5, heating agent house steward 6, heating agent delivery pipe 7, valve 8.The annexation of valve 8, pipeline, equipment is, valve 8-1 connects the inlet tube 4-1 of heating agent house steward 6 and last chuck 1, valve 8-2 connects the inlet tube 4-2 of heating agent house steward 6 and following chuck 2, the outlet 5-2 of chuck 2 and the inlet tube 4-1 of last chuck 1 under valve 8-3 connects, valve 8-4 connects the outlet 5-2 and the heating agent delivery pipe 7 of chuck 2 down, the outlet 5-1 of chuck 1 and heating agent delivery pipe 7 in the valve 8-5 connection.Connected mode can directly connect, and also available pipe connects, and the above connection all is fixed seal connection.
According to above requirement, heater has following chuck 2, goes up chuck 1, is welded with alternating expression deflection plate 3 in the chuck, and alternating expression deflection plate 3 makes heat conduction thing even distribution heating in pipe, increases heat-transfer effect, reduces the error that temperature difference is brought to reaction as far as possible; Pipeline adopts the seamless steel pipe of wall thickness 3.5, latus rectum 50, and this kind steel pipe sealing is firm, has strengthened the security of this reaction unit; Valve adopts the valve of Pg16, Dg50, and this valve employing hand can make the process of reaction upgrade flexibly, be convenient to regulate, and jacket type classification heater of the present utility model, similarly other reaction vessels are also suitable to production technology.
The opening and closing that work implementation of the present utility model is a by-pass valve control can realize multiple mode of heating:
Independent mode of heating: valve 8-2 unlatching, valve 8-4 unlatching, other valve closings, chuck 2 heating down, valve 8-1 unlatching, valve 8-5 unlatching, other valve closings, upward chuck 1 heating.
The series connection mode of heating: valve 8-2 opens, valve 8-3 opens, valve 8-5 opens, other valve closings, following chuck 2 and the 1 series connection heating of last chuck.
Mode of heating in parallel: valve 8-3 closes, other valves are all opened, descend chuck 2 and 1 parallel connection of last chuck to heat simultaneously.
Because the magnitude difference of reaction mass, less at reaction starting stage material, material position in device is lower, to chuck 2 heating down; Increase at reaction later stage material, the position of material in device rises to certain altitude, to last chuck 1 heating; At long-time holding stage, then to down chuck 2 and the 1 series connection heating of last chuck, can control the fluctuation range of temperature of charge in the still effectively, make product molecular weight distribution more evenly, energy-conserving and environment-protective, satisfied the manufacturing technique requirent of extraordinary product.
