Abstract
The utility model provides a shell and tube type heat exchanger admission distributor's technical scheme, the admission union coupling of this scheme admission sleeve pipe to the heat exchanger shell, the sleeve pipe is in the outside of tube, both ends adopt the baffle to seal between sleeve pipe and tube about the sleeve pipe, and vacuole formation between the casing, it has the admission opening to open on the tube in the cavity, the admission opening is outside to be connected with the cavity, inside and tube internal connection, this kind of structure makes the steam that gets into the admission pipe get into earlier the cavity, steam because the increase velocity of flow of admission area is showing reduces, the steam that gets into in the cavity is followed again the admission opening in get into the tube in, carry out the heat transfer with the heat exchange tube. The reduction of the steam velocity of flow to the impact of heat exchange tube, and then lengthened the life of heat exchange tube.
Description
Technical field
The utility model relates to a kind of heat exchanger admission distributor, especially a kind of shell-and-tube heat exchanger admission distributor.
Background technology
Shell-and-tube heat exchanger generally designs and walks steam from shell side, tube side is leaked water carries out heat exchange, directly steam is entered when steam inlet steam flow velocity is lower at the steam inlet pipe of shell side welding, baffle plate is installed additional at steam inlet when steam inlet steam flow velocity is higher, formed to prevent steam heat exchanging pipe and impact and produce destruction, what also have is designed to various structure achieve the above object by steam inlet pipe.Existing shell-and-tube heat exchanger admission distributor such as Patent Office of State Intellectual Property Office authorizes disclosed application number to be No. 2013106402653 art solutions, disclose a kind of distributor being applicable to shell and tube exchanger, be air intake is designed to body and be located at successively along media flow direction described body medium channel, throttling speed-raising plate, break up body and distribute passage; Describedly break up body and throttling and raise speed and between plate, form the structure of hybrid chamber, it can will enter the steam distribution of heat exchanger to breaing up body, heat exchanger heat exchange is entered after entering throttling speed-raising plate, the mixed vapour front of ejection hits heat exchanger tube, direct heat exchanging pipe is formed and impacts, not only do not solve shock problem, but directly increase impact, directly reduce the service life of heat exchanger tube.Existing additive method can only install baffle plate additional in heat exchanger import, occupies the inside useful space of heat exchanger, and the impact of exchange heat pipe is still very large, and effectively do not solve steam impringement problem, this is the weak point existing for prior art.
Summary of the invention
Technical problem to be solved in the utility model, be exactly for the deficiency existing for prior art, and a kind of technical scheme of shell-and-tube heat exchanger admission distributor is provided, the program installs steam inlet device additional on the surface of shell-and-tube heat exchanger admission position shell, this device is by admission space larger for steam guiding, inlet steam flow velocity is reduced, these steam enter shell inside from shell air admission hole again and carry out heat exchange with heat exchanger tube, reduction due to inlet steam flow velocity just reduces the impact of exchange heat pipe, extends the service life of heat exchanger tube.
This programme is achieved by the following technical measures: steam inlet pipe is connected to the admission sleeve pipe on outer cover of heat exchanger, sleeve pipe is in the outside of shell, the upper and lower two ends of sleeve pipe adopt baffle plate to close between sleeve pipe and shell, and form cavity between housing, in cavity, shell has admission opening, admission opening outside is connected with cavity, inside is connected with shell inside, this structure makes the steam entering steam inlet pipe be introduced into cavity, steam is because the increase flow velocity of admission area significantly reduces, the steam entered in cavity enters in shell again in above-mentioned admission opening, heat exchange is carried out with heat exchanger tube.The impact reducing exchange heat pipe of described steam flow rate, and then extend the service life of heat exchanger tube.The other technical characterstic of this programme is exactly because admission sleeve pipe is outside at shell, does not take inner space, can arrange more heat exchanger tube in shell, increases the heat exchange amount of heat exchanger.
The beneficial effect of this programme can be learnt according to describing of such scheme, after fluid flows to cavity, vapour volume undergoes rapid expansion, flow velocity reduces rapidly, to gather to the admission opening on shell also by original enlarged areas compared with steam inlet pipe several times, also reduce the flow velocity by shell, and then reduce the impact of exchange heat pipe.Because sleeve pipe does not take inner space, so more heat exchanger tube can be installed additional in shell, increase the heat exchange amount of heat exchanger.As can be seen here, compared with prior art, have outstanding substantive distinguishing features and significant progress, its beneficial effect implemented also is apparent to the utility model.
accompanying drawing illustrates:
Fig. 1 is the structural representation of the utility model detailed description of the invention, and Fig. 2 is admission position profile figure.
In figure, 1 baffle plate, 2 sleeve pipes, 3 steam inlet pipes, 4 admission openings, 5 tubular heat exchanger tube sheets, 6 heat exchanger tubes, 7 pipe for shell-and-tube exchanger shells.
detailed description of the invention:
For the technical characterstic of this programme can be clearly demonstrated, below by a detailed description of the invention, and in conjunction with its accompanying drawing, this programme is set forth.
Can be found out by accompanying drawing, the shell-and-tube heat exchanger admission distributor of this programme, by steam inlet pipe, sleeve pipe, baffle plate, admission opening, shell forms, steam inlet pipe is connected to the admission sleeve pipe on outer cover of heat exchanger, sleeve pipe is in the outside of shell, the upper and lower two ends of sleeve pipe adopt baffle plate to close between sleeve pipe and shell, and form cavity between housing, in cavity, shell has admission opening, admission opening outside is connected with cavity, inside is connected with shell inside, this structure makes the steam entering steam inlet pipe be introduced into cavity, steam is because the increase flow velocity of admission area significantly reduces, the steam entered in cavity enters in shell again in above-mentioned admission opening, heat exchange is carried out with heat exchanger tube.Described steam flow rate reduces the impact decreasing exchange heat pipe, and then extends the service life of heat exchanger tube.
Claims (2)
1. a shell-and-tube heat exchanger admission distributor, comprise by steam inlet pipe, sleeve pipe, baffle plate, admission opening, shell forms, steam inlet pipe is connected to the admission sleeve pipe on outer cover of heat exchanger, sleeve pipe is in the outside of shell, the upper and lower two ends of sleeve pipe adopt baffle plate to close between sleeve pipe and shell, and form cavity between housing, in cavity, shell has admission opening, admission opening outside is connected with cavity, inside is connected with shell inside, this structure makes the steam entering steam inlet pipe be introduced into cavity, the steam entered in cavity enters in shell again in above-mentioned admission opening, heat exchange is carried out with heat exchanger tube.
2. shell-and-tube heat exchanger admission distributor according to claim 1, is characterized in that: when entering the steam of described steam inlet pipe, be introduced into cavity, then enters shell-and-tube heat exchanger inside by admission opening.
