Abstract
The utility model relates to a heat exchanger tube-pass anti-scour device, wherein an air inlet is sealed and fixed on the left end of a heat exchanger tube box, a heat exchange tube is sealed and fixed on the right end, a baffle is fixed inside the heat exchanger tube box and closely to the heat exchange tube, and a gap is disposed on the baffle so that high-pressure and high-acidity natural gas is stopped by the baffle and then enters the heat exchange tube by the gap. According to the utility model, direct scour of the high-pressure and high-acidity natural gas on a tube plate and ends of the heat exchange tube is avoided, the gas can enter the heat exchange tube slowly and uniformly, erosion to the tube plate and the heat exchange tube is reduced and sulfur deposition at end holes of the heat exchange tube is reduced.
Description
Technical field
The utility model belongs to technical field of heat exchangers, and a kind of heat exchanger tube pass checking motion is particularly provided.
Background technology
My company is the peracidity gas field trial chamber that Sinopec is established, designed a collection of skid shell-and-tube heat exchanger, through this heat exchanger heat temperature raising or refrigeration cool-down, carry out again throttling pressure regulation, the multiple actual production conditions such as simulated high-pressure peracidity natural gas pit shaft, surface gathering and transferring, test the dynamic data of various burn into sulphur deposition and hydrate.This heat exchanger tube pass peracidity gas feed axially arranges, and high velocity gas stream flings tube sheet, and meeting directly etching tube sheet and heat exchanger tube, not only reduce service life, and in heat exchanger tube end, forms sulphur deposition.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of heat exchanger tube pass checking motion, solve the high pressure direct flush pipe plate of peracidity natural gas and heat exchanger tube end, make it evenly enter slowly heat exchanger tube, the erosion of minimizing to tube sheet and heat exchanger tube, and reduce the sulphur deposition of heat exchanger tube port.
The technical scheme in the invention for solving the technical problem is: the left end sealing of heat exchanger bobbin carriage fixedly air inlet right-hand member seals fixedly heat exchanger tube, close heat exchanger tube fixed dam in heat exchanger bobbin carriage, jagged on baffle plate, make high pressure peracidity natural gas be subject to by breach, entering heat exchanger tube after stopping of baffle plate.
The utlity model has following advantages: 1), both prevented the direct erosion tube sheet of natural gas and heat exchanger tube, can prevent that again sulfide is in the accumulation of heat exchange tube inlet place, the service life of having improved heat exchanger; 2) the bouble-bow v notch v of arranging, up and down, had both reduced the impulsive force of gas to baffle plate, had guaranteed again the unobstructed eliminating of dirt, rational in infrastructure; 3), gas is by impingement baffle baffle plate, and the high flow rate of import department moment is slowed down, and reduced the impulsive force of bobbin carriage and heat exchanger tube, makes heat exchanger tube obtain good protection; 4), rational in infrastructure, safe, meet the life expectancy requirement of heat exchanger, reduced the erosion to bobbin carriage tube sheet and heat exchanger tube, reduced the sulphur deposition of heat exchanger tube port.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the utility model cutaway view;
Fig. 2 is that A in the utility model Fig. 1 is to view.
The specific embodiment
As shown in Figure 1, the left end sealing of heat exchanger bobbin carriage 2 fixedly air inlet 1 right-hand member seals fixedly heat exchanger tube 5, heat exchanger bobbin carriage 2 is interior near heat exchanger tube 5 fixed dams 3, jagged 4 on baffle plate 3, makes high pressure peracidity natural gas be subject to by breach 4, entering heat exchanger tube 5 after stopping of baffle plate 3.
Described baffle plate 3 has upper and lower two breach 4.
On described baffle plate 3 except the central area that air inlet 1 liquidates uniform aperture 6.
The aperture area sum of described baffle plate 3 and two breach area summations are greater than the circulation area of air inlet 1, are less than total circulation area of heat exchanger tube.
High pressure peracidity natural gas enters from air inlet 1, the high-velocity fluid of import department moment, and after stopping by baffle plate 3, speed slows down, and then, evenly by aperture around 6 and two breach 4, flows to heat exchanger tube 5, reduces the erosion to tube sheet and heat exchanger tube.
