Abstract
The invention provides an electric heating device for a high-corrosion medium, wherein the electric heating device can be used for enabling the high corrosion medium to corrode an electric heating pipe uniformly, and effectively preventing the situation that damages to the electric heating pipe are mostly generated at a high-temperature end of the electric heating pipe adjacent to a medium outlet so as to prolong the service life of the electric heating pipe. The electric heating device for the high-corrosion medium comprises a pipe body, a medium inlet, the medium outlet and the electric heating pipe, wherein the electric heating pipe is arranged in the pipe body; and the electric heating device is characterized in that at least two longitudinally interlaced baffles are arranged in the pipe body, each baffle is provided with a baffle notch, the baffle notches are staggered up and down, and the baffle notches are gradually narrowed along the flow direction of the medium.
Description
Technical field
The present invention relates to the technical field of fluid media (medium) treatment facility, be specially a kind of electric heater unit of highly corrosive medium.
Background technology
In petroleum chemical industry, need handle uniform temperature to fluid media (medium) sometimes, need fluid medium to heat; Existing electric feeder apparatus is when the medium of heating highly corrosive, and import is in the flow process of outlet, and temperature raises gradually; Flow velocity is even; Corrosivity is along with the rising of temperature, and corrosivity is strengthened gradually, mostly occurs in the temperature end near media outlet thereby the electrothermal tube damage takes place.
Summary of the invention
To the problems referred to above; The invention provides a kind of electric heater unit of highly corrosive medium; Make the highly corrosive medium realize homogeneous corrosion, prevented that effectively the electrothermal tube damage from mostly occurring in the temperature end near media outlet electrothermal tube, thus the service life of having improved electrothermal tube.
Its technical scheme is such: a kind of electric heater unit of highly corrosive medium, and it comprises body, the medium import; Media outlet and electrothermal tube; Said electrothermal tube is arranged in the said body, it is characterized in that: be provided with the deflection plate of at least two vertical interlaced arrangement in the said body, said deflection plate is provided with baffle gap; Said baffle gap is staggered up and down, and said baffle gap diminishes along the media flow direction gradually.
It is further characterized in that: said electrothermal tube passes said arrangement of baffles; Said body is two bodys, and said medium import is arranged on one of them body, and said media outlet is arranged on another body, connects through flange between said two bodys, realizes the two-stage heating; Said deflection plate is 12 deflection plates, is evenly arranged in said two bodys.
In the said structure of the present invention, owing in the electric heater unit body deflection plate that diminishes gradually along media flow direction breach is set, along the media flow direction; It is big that flow velocity becomes gradually; Medium temperature raises, and the electrothermal tube surface temperature does not raise, and realizes electrothermal tube homogeneous corrosion along its length; Prevented that effectively the electrothermal tube damage from mostly occurring in the temperature end near media outlet, thus the service life of having improved electrothermal tube.

Fig. 3 is deflection plate schematic cross-section in the electric heater unit of highly corrosive medium of the present invention.
The specific embodiment
See Fig. 1, Fig. 3; The electric heater unit of a kind of highly corrosive medium of the present invention; It comprises body 2-1 and 2-2, medium import 5, media outlet 6 and the electrothermal tube 1-1 and the 1-2 that are separately positioned in body 2-1 and the 2-2; Be connected through flange 3 between body 2-1 and 2-2; Realized the two-stage heating of flow media, body 2-1 and 2-2 are interior evenly to be provided with deflection plate 4-1,4-2,4-3,4-4,4-5,4-6,4-7,4-8,4-9,4-10,4-11 and the 4-12 of 12 vertical interlaced arrangement along the media flow direction, and electrothermal tube 1 passes deflection plate; Be respectively arranged with baffle gap 7-1,7-2,7-3,7-4,7-5,7-6,7-7,7-8,7-9,7-10,7-11 and 7-12 on deflection plate 4-1,4-2,4-3,4-4,4-5,4-6,4-7,4-8,4-9,4-10,4-11 and the 4-12; Baffle gap is staggered up and down, and is maximum near the baffle gap 7-1 of MEDIA FLOW porch, minimum near the baffle gap 7-12 of MEDIA FLOW outlet.(small circular is an electrothermal tube among Fig. 3)
Diminish gradually owing to be provided with along media flow direction baffle gap in the electric heater unit body; Along the media flow direction, flow velocity becomes greatly gradually, and medium temperature raises; The electrothermal tube table does not raise; Realize electrothermal tube homogeneous corrosion along its length, prevented that effectively the electrothermal tube damage from mostly occurring in the temperature end near media outlet, thus the service life of having improved electrothermal tube.
Adopt two bodys and two cover electrothermal tubes in the present embodiment; Realized the two-stage heating of flow media; Two bodys evenly are provided with 12 notched deflection plates, and the present invention can adopt a body and a cover electrothermal tube certainly, realizes the one-level heating; Also can adopt a plurality of bodys and many cover electrothermal tubes to realize multistage heating; The notched deflection plate of other quantity also can be set in the body, as long as vertically be furnished with the deflection plate that breach diminishes gradually along the media flow direction in the body, all is the scope that the present invention protects.
