Description
Technical field
Chemical industry technical field of heat exchange equipment is the utility model is related to, more particularly to a kind of heat exchanger fluid erosion prevention device.
Background technology
At present, the chemical production device gas condenser of hydraulic art is prohibited, mostly vertical double tubesheet stuffing box type tubulation changes
The structure design of hot device, using water as cooling medium, contain HCL component gas phase media for condensing.The heat exchanger tube of heat exchanger is general
Using nickel-base alloy, involve great expense.Limited by medium physical property, contain a small amount of liquid from the gas for flashing groove tank or rectifying column etc.
Droplet, this process gas containing drop are directly entered condenser, and its gas medium flow velocity is entrained up to tens of rice per second
Fog-like liquid directly act on condenser medium inlet side pipe plate top and heat exchanger tube, drop flow velocity is considerably beyond nickel-base alloy
The flow rate of liquid that can bear, exchanges heat pipe and tube sheet causes serious erosion damage, substantially reduces the service life of condenser.
Utility model content
The technical problems to be solved in the utility model is to be directed to above-mentioned the deficiencies in the prior art, there is provided a kind of heat exchanger erosion control
Device is lost, for this device as a kind of buffer unit, the process gas for reducing entrained drip exchanges the erosion damage of thermal tubulation,
Extend the heat exchanger life-span.
In order to solve the above technical problems, technical solution adopted in the utility model is：A kind of heat exchanger fluid erosion prevention device,
Including the first tube sheet, the second tube sheet and tubulation, the first tube sheet and the second tube plate structure are identical, are equipped with mounting hole, tubulation both ends
Fixed by mounting hole and the first tube sheet and the second Tube-sheet Welding.
Further, the second tube sheet is along the circumferential direction uniformly provided with bolt hole.
Further, tubulation the first tube sheet protrusion relative with one end that the first tube sheet connects.
Further, tubulation the second tube sheet retraction relative with one end that the second tube sheet connects.
Further, the length of tubulation is 300mm-320mm.
Further, the first tube sheet, the second tube sheet and tubulation use stainless steel.
It is using beneficial effect caused by above-mentioned technical proposal：The present apparatus is arranged on vertical double tubesheet pipe bundle condenser
At upper perforated plate, as bolster, play uniform and cushioning effect, reduce the process gas of entrained drip to condenser upper perforated plate and
The erosion of tubulation, extend the heat exchanger life-span.

Embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
As depicted in figs. 1 and 2, it is a kind of one embodiment of heat exchanger fluid erosion prevention device of the utility model, including first
Tube sheet 1, the second tube sheet 2 and tubulation 3, the first tube sheet 1 is identical with the structure of the second tube sheet 2, is equipped with mounting hole, and the both ends of tubulation 3 lead to
Mounting hole is crossed to be welded and fixed with the first tube sheet 1 and the second tube sheet 2.
Condenser technique side air inlet medium source is flash process from decoking tower, the tower, and the gas phase media that it is flashed off is by about
Direction shown in the pipeline along Fig. 3 arrows of 10m length is directly entered condenser, is limited by processing medium physical property, and centre is without any gas-liquid
Separator.Therefore it is in fine droplet state to actually enter in the gas phase media of condenser containing a certain amount of liquid phase component, separately
Outside, the heat waste of gas phase pipeline causes part high temperature saturated vapor to condense back liquid phase, is blown under airflow function from duct bottom
Condenser.The upper perforated plate of the direct heat exchanging device inlet side of this two parts liquid phase medium causes serious in the presence of high velocity air
Erosion.The upper perforated plate of the second tube sheet of the utility model device 2 and vertical double tubesheet pipe bundle condenser 6 is bolted, condensation
The upper perforated plate of device 6 is bolted on public attention 5 and exported, and the pipeline of public attention 5 is formed as the utility model shell and sealed.
Second tube sheet 2 is along the circumferential direction uniformly provided with bolt hole 4.The utility model device is bolted to connection vertical
At the upper perforated plate of formula double tubesheet pipe bundle condenser 6, the piping mode of the first tube sheet 1 and the second tube sheet 2, mounting hole size with condensation
The tube sheet of device 6 is identical, and piping mode and the quantity of condenser 6 are not limited to quantity and mode provided by the utility model.This practicality
, should be with the tube sheet parallel misalignment of condenser 6≤0.4mm, tubulation 3 and condenser 6 after new device assembles with the upper perforated plate of condenser 6
Heat exchanger tube perpendicularity deviation≤0.4mm, Concentricity tolerance≤0.2mm.
As shown in figure 1, the first tube sheet 1 relative with one end that the first tube sheet 1 connects of tubulation 3 protrudes.
As shown in Figures 2 and 3, the second tube sheet 2 relative with one end that the second tube sheet 2 connects of tubulation 3 is retracted.Tubulation 3 and
The connection of one tube sheet 1 uses typical heat exchanger tube welding manner, and tubulation protrusion tube sheet can form angle welding, make foot welding height higher,
Reach 4MM, it is ensured that weld strength.And tubulation 3 is connected the retraction mode that uses with the second tube sheet 2, it can mainly make condenser 6
Heat exchanger tube head depth enters the second tube sheet, plays a part of positioning and eliminating gap, reduces the possibility for producing crevice corrosion, general retraction
Depth is 3MM.
The length of tubulation 3 is 300mm-320mm.The height of the utility model device is according to the reality of the heat exchanger tube of condenser 6
Lesion depths determine, and increase certain surplus.
First tube sheet 1, the second tube sheet 2 and tubulation 3 use stainless steel.Using 304 stainless steels, have excellent
Corrosion-resistant and high-temperature resistant performance, and the expensive nickel-base alloy tubulation of relative price has price advantage, is easily changed.
Beneficial effect：The present apparatus is arranged at vertical double tubesheet pipe bundle condenser upper perforated plate, as bolster, is played uniform
And cushioning effect, erosion of the process gas of entrained drip to condenser upper perforated plate and tubulation is reduced, extends the heat exchanger longevity
Life.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
