At chemical enterprise, often use the tubular heat exchanger of a kind of from top to bottom charging and erect-type installation.Because the feeding manner of said tubular heat exchanger is special, when design, can install a distribution plate additional in import department, guarantee the even distribution of charging and slow down through distribution plate because the heat exchanger tube sheet that lumped scour causes and the damage at heat exchanger tube place.In addition, said distribution plate is provided with the drain hole that is used for the overflow material, and said drain hole is used at the common overflow material of said distribution plate.Yet; In use; Under all high situation of material flow and granule content; Said drain hole can't corresponding said distribution plate the overflow material, also be difficult to guarantee the even distribution of charging and slow down because the heat exchanger tube sheet that lumped scour causes and the damage at heat exchanger tube place through distribution plate.
In addition, when the difference of material, also can cause the difference damage of distribution plate because of flow velocity and particle.Under all high situation of material flow and granule content; The service life of general normal allocation dish is not long; In case damage, material can directly be punched on the tube sheet and heat exchanger tube of heat exchanger, causes heat exchanger tube and the tube sheet body of heat exchanger and seals to leak because of damage thus.
The utility model content
For overcoming the problems referred to above, the utility model purpose is, a kind of heat exchanger distribution plate of erosion is provided, the heat exchanger distribution plate of said erosion be used for vertical installation, tube side liquid phase import tubular heat exchanger up.The utility model is weld nipple on the hole on the distribution plate, and material is flowed down through this short tube overflow, and on distribution plate, forms the liquid level of certain altitude.Utilize this liquid level, under all high situation of material flow and granule content, can avoid the material of high flow rate directly to be punched on the distribution plate, play cushioning effect, thereby solve the erosion problem of distribution plate distribution plate.
The technical scheme of the heat exchanger distribution plate of the erosion of the utility model is following:
A kind of heat exchanger distribution plate of erosion, be used for vertical installation, tube side liquid phase import tubular heat exchanger up, comprise distribution plate; Said distribution plate is provided with the drain hole that is used for the overflow material, it is characterized in that, said distribution plate is arranged at said tubular heat exchanger top; Distribution plate fixedly installs on the shelf; Said shelf is welded on the end socket, and the short tube that said distribution plate setting is corresponding with the heat exchanger tube pore of tubular heat exchanger makes material under all high situation of material flow and granule content; Can descend through this short tube overflow, and on distribution plate, form the liquid level of certain altitude.
Heat exchanger distribution plate according to the erosion of the utility model is characterized in that said short tube is welded on the distribution plate, and the pore aperture of said short tube is corresponding with the heat exchanger tube of tubular heat exchanger.
Heat exchanger distribution plate according to the erosion of the utility model is characterized in that said short tube length is 20-30mm.
Thus, when material is flowed down through this short tube overflow, can on distribution plate, form the liquid level of 20-30mm height.
Heat exchanger distribution plate according to the erosion of the utility model is characterized in that the wall thickness of said short tube is corresponding with the heat exchanger tube wall thickness of tubular heat exchanger.
Heat exchanger distribution plate according to the erosion of the utility model is characterized in that the pore quantity of said short tube is corresponding with the heat exchanger tube of tubular heat exchanger.
Heat exchanger distribution plate according to the erosion of the utility model is characterized in that the arrangement mode of said short tube is corresponding with the heat exchanger tube of tubular heat exchanger.
Heat exchanger distribution plate according to the erosion of the utility model is characterized in that, said distribution plate is fixing on the shelf by set bolt.
According to the heat exchanger distribution plate of the erosion of the utility model, the heat exchanger distribution plate of said erosion be used for vertical installation, tube side liquid phase import tubular heat exchanger up.The utility model welds one section short tube on the hole on the distribution plate, material is flowed down through this short tube overflow, and on distribution plate, forms the liquid level of certain altitude.Utilize this liquid level, can avoid the material of high flow rate directly to be punched on the distribution plate, play cushioning effect, thereby solve the erosion problem of distribution plate distribution plate.
