Abstract
The utility model relates to a novel shell-and-tube heat exchanger comprising a tube shell, a heat radiating pipe and baffle plates. The heat radiating pipe is disposed in the tube shell; a plurality of corresponding baffle plates are arranged in the tube shell; each baffle plate is arch-shaped with the diameter slightly smaller than the internal diameter of the tube shell; the thickness of each baffle plate is 2 to 3mm; corresponding through holes for serial connection of the heat radiating pipe are arranged on each baffle plate; and the heat radiating pipe passes through the corresponding through holes on each baffle plate and is arranged in the tube shell. The baffle plates are made of PE material, thereby possessing excellent low temperature resistance, great chemical stability and corrosion resistance of most acid-bases; the baffle plate is insoluble in common solvents at a normal temperature; the baffle plate is characterized by small water-absorbing property and excellent electrical insulation performance; and not only the baffle plate cannot be corroded but material cost can be reduced, so an application range of the shell-and-tube heat exchanger is enlarged, service life is prolonged and cost is reduced.
Description
Technical field
The utility model relates to pipe shell type heat exchange equipment, is specifically related to a kind of novel shell-and-tube heat exchanger.
Background technology
Shell-and-tube heat exchanger uses extensively in oil refining, petrochemical industry, medicine, chemical industry and other industry, and it is applicable to the various aspects such as cooling, condensation, heating, evaporation and Waste Heat Recovery.Although shell-and-tube heat exchanger is not so good as other novel heat transmission equipment at aspects such as the volume of heat exchange efficiency, equipment and the consumptions of metal material, but it has the advantages such as firm in structure, operating flexibility is large, the degree of reliability is high, the scope of application is wide, so still generally used in each engineering.In the shell of shell-and-tube heat exchanger, be provided with deflection plate, it had both improved heat-transfer effect, also played the effect of supporting radiating tube simultaneously.The deflection plate that its shell inside of existing shell-and-tube heat exchanger is provided with is to be generally prepared from by metal material, shell-and-tube heat exchanger is applied in compressed air purifying industry, because compressed air contains a large amount of steam and trace acidic medium, through long-term use, metal baffles corrosion be can cause, and heat-transfer effect and the effect of supporting tube bank lost.Therefore for the solution of above-mentioned prior art problem, be, research purpose of the present utility model.
Summary of the invention
For above-mentioned the deficiencies in the prior art part, the utility model is to provide a kind of novel shell-and-tube heat exchanger, can effectively solve the problem that above-mentioned prior art exists.
The technical solution of the utility model is:
A kind of novel shell-and-tube heat exchanger, comprise shell, radiating tube and deflection plate, described radiating tube is installed in described shell, in described shell, be provided with multiple corresponding deflection plates, described deflection plate is the segmental baffle that a diameter is slightly less than shell internal diameter, described deflection plate is to be prepared from by PE material, and described deflection plate thickness is 2-3mm; Described deflection plate is provided with the respective through hole for being connected in series radiating tube, and described radiating tube passes the respective through hole device of each deflection plate in described shell; Described shell-and-tube heat exchanger is during as evaporimeter, and the weight of described radiating tube is 0.8 ± 0.5～42 ± 0.5Kg, and the spacing of described deflection plate becomes along with the increase of the weight of radiating tube greatly, and the spacing between adjacent baffle is 16 ± 5～174 ± 5mm; Described shell-and-tube heat exchanger is during as heat exchanger, and the weight of described radiating tube is 2.5 ± 0.5～52 ± 0.5Kg, and the spacing of described deflection plate becomes along with the increase of the weight of radiating tube greatly, and the spacing between adjacent baffle is 58 ± 5～165 ± 5mm.
Described deflection plate is equidistantly installed in described shell, and the transverse incision opposite direction between every adjacent two deflection plates and device are on described shell.
Described radiating tube is through the respective through hole of each deflection plate, and the mode of employing expand tube frock is the respective through hole at described deflection plate by radiating tube positioner.
Advantage of the present utility model: deflection plate of the present utility model adopts and is prepared from by PE material, its odorless, nontoxic, feel ceraceous, have that good resistance to low temperature (minimum serviceability temperature can reach-70～100 ℃), chemical stability are good, the erosion of the most of soda acids of ability, and be insoluble to common solvent under normal temperature; This deflection plate also has the features such as water imbibition is little, electrical insulation capability is good, density is low, good toughness, can replace the deflection plate that original metal material is prepared from, and can not be corroded and can reduce material cost; So, just make the scope of application of shell-and-tube heat exchanger expand, the life-span improves, cost.
