Abstract
The utility model discloses a kind of high efficiency low pressure drop helical baffles corrugated tube heat exchanger, including being arranged on heat exchanger shell internal coiling deflection plate, tube sheet and corrugated tube, helical baffles is provided with some diameters through hole more than corrugated tube, tube sheet is fixed on housing both sides, corrugated tube level runs through the through hole on helical baffles makes helical baffles can horizontally slip on corrugated tube, and the two ends of corrugated tube are separately fixed in tube sheet, the two ends of helical baffles level connection joint respectively has spring, and the end of spring is fixing with tube sheet to be connected.Compared with prior art, high efficiency low pressure drop helical baffles corrugated tube heat exchanger of the present utility model, after fluid enters heat exchanger shell, owing to the effect helical baffles of spring can horizontally slip on corrugated tube repeatedly, so can eliminate triangle dead band, corrugated tube contacts more abundant with the fluid in housing, reduces dirt deposits in corrugated tube, thus reduces the flow resistance of medium thus the pressure medium loss that decreases in diabatic process.
Description
Technical field
This utility model relates to a kind of heat exchanger, particularly a kind of high efficiency low pressure drop helical baffles corrugated tube heat exchanger.
Background technology
Helical baffles corrugated tube heat exchanger be one be widely used in electric power, oil, chemical industry, metallurgy, petrochemical industry, weaving,
Novel among the various fire coals of industry, fuel-oil or fuel-gas boiler, kiln, gas injection stove, heating furnace and various heat transmission equipment such as medicine
Energy-efficient patented technology and device.But can shape during the distribution of the helical baffles of existing helical baffles corrugated tube heat exchanger
Becoming a triangle " dead band ", the corrugated tube in triangle " dead band " amasss little with the fluid contact level in housing, the impact of suffered fluid
Power is the least, is therefore easy to dirt deposits in the corrugated tube in triangle " dead band ", thus considerably increases the flow resistance of medium
Thus add the pressure medium loss in diabatic process.
Summary of the invention
The purpose of this utility model is intended to solve the deficiency of prior art problem, it is provided that a kind of high efficiency low pressure drop spiral baffling
Plate corrugated tube heat exchanger.
For reaching above-mentioned purpose, this utility model is implemented according to techniques below scheme:
A kind of high efficiency low pressure drop helical baffles corrugated tube heat exchanger, including being arranged on heat exchanger shell internal coiling baffling
Plate, tube sheet and corrugated tube, described helical baffles offers some diameters through hole more than corrugated tube, and tube sheet is fixed on housing
Both sides, described corrugated tube level runs through the through hole on helical baffles makes helical baffles can horizontally slip on corrugated tube, and
The two ends of corrugated tube are separately fixed in tube sheet, and the two ends of described helical baffles level connection joint respectively has spring, the end of spring
Portion is fixing with tube sheet to be connected.
Further, being provided with some transverse slats with the outer ring surface edge the tangent level of helical baffles, transverse slat passes through little spring
It is connected to inner walls.
Compared with prior art, high efficiency low pressure drop helical baffles corrugated tube heat exchanger of the present utility model, when fluid enters
After entering heat exchanger shell, owing to the effect helical baffles of spring can horizontally slip on corrugated tube repeatedly, so can eliminate
Triangle dead band, corrugated tube contacts with the fluid in housing more abundant, reduces dirt deposits in corrugated tube, thus greatly reduce
The flow resistance of medium thus decrease the pressure medium loss in diabatic process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is further described by specific embodiment, in the signal of this utility model
Property embodiment and explanation be used for explaining this utility model, but be not intended as restriction of the present utility model.
A kind of high efficiency low pressure drop helical baffles corrugated tube heat exchanger as shown in Figure 1, including being arranged on heat exchanger shell 1
Internal coiling deflection plate 4, tube sheet 2 and corrugated tube 3, described helical baffles 4 offers some diameters through hole more than corrugated tube 3
5, tube sheet 2 is fixed on housing 1 both sides, and described corrugated tube 3 level runs through the through hole 5 on helical baffles 4 makes helical baffles 4 energy
Horizontally slipping on corrugated tube 3, and the two ends of corrugated tube 3 are separately fixed in tube sheet 2, the two ends of described helical baffles 4 are divided
Other level connection joint has spring 8, and the end of spring 8 is fixing with tube sheet 2 to be connected.After fluid enters heat exchanger shell 1, due to fluid
Transverse pressure to helical baffles 4, the spring 8 at the two ends of helical baffles 4 one of them would be at extended state another
Individual, compressive state can be gone out, helical baffles 4 horizontally slips repeatedly on corrugated tube 3 like this, eliminates the need for helical baffles 4
Triangle dead band.
In order to increase the radial impact force to corrugated tube 3 of the fluid in housing 1, prevent dirt deposits in corrugated tube 3, with spiral shell
The outer ring surface edge the tangent level of rotation deflection plate 4 is provided with some transverse slats 6, and transverse slat 6 is connected to housing 1 inwall by little spring 7.
The technical solution of the utility model is not limited to the restriction of above-mentioned specific embodiment, every according to skill of the present utility model
The technology deformation that art scheme is made, within each falling within protection domain of the present utility model.
