The pipe joint of existing vertical high-pressure feed-water heater ubiquity heat exchanger tube is advanced water and is impacted and the easy problem of damaging, and generally takes to serve as a contrast stainless joint as the erosion control parts at the mouth of pipe place of every heat exchanger tube, because heat exchanger tube quantity is many, realizes very difficult.The problems such as the easy leakage of blast pipe weld seam of self sealss parts dismounting difficulty, high pressure tube side when in addition, also existing heater to install and overhaul.
Summary of the invention
The purpose of this utility model is the problem that exists at prior art, and a kind of vertical high-pressure heater is provided, and it is rational in infrastructure, and is easy for installation, can avoid the pipe joint of heat exchanger tube to be advanced water and impact and damage; In addition, self sealss parts dismounting, maintenance are conveniently; Can avoid the blast pipe weld leakage of high pressure tube side.
The purpose of this utility model is achieved through the following technical solutions:
A kind of vertical high-pressure heater, form by housing, heat-exchanging tube bundle and hydroecium, hydroecium comprises cylindrical shell, feed-water inlet, self-seal device, top cover, drainpipe, pass partition and blast pipe, it is characterized in that the heat exchanger tube top near the feed-water inlet place is provided with a cowling panel that is provided with in the described hydroecium, offer on the cowling panel that diameter is identical with the heat exchanger tube internal diameter, quantity and heat exchanger tube aperture one to one, and the center of each aperture and corresponding heat exchanger tube mouth of pipe center are on same vertical line.
To improvement of the technical scheme: described cowling panel is the whole piece stainless steel flat plate, is horizontally set on the heat exchanger tube top.
To further improvement in the technical proposal: have a through hole on the described top cover, the self-seal device of through hole below is provided with the lifting suspension ring.
To further improvement in the technical proposal: the spigot-and-socket welding is adopted in the welding of described blast pipe and hydroecium.
The utility model compared with prior art has many advantages and good effect:
1, the feed-water inlet place of the utility model in hydroecium is provided with the stainless steel cowling panel, and the erosion of not fed water of protection tube joint is simple and reasonable for structure.
2, the utility model perforate and lifting is set on self-seal device use suspension ring on the top cover of hydroecium, when being convenient to install and overhaul to the lifting of the self-seal device of heaviness.
3, socket weld is adopted in the welding of blast pipe of the present utility model and hydroecium cylindrical shell, has improved the intensity of weld seam, has solved the problem of weld leakage.
Its structural design is reliable, the operational percentage height, and service life of equipment is long, and maintenance is convenient.
Description of drawings
Fig. 1 is the outline drawing of the vertical high-pressure heater of the utility model;
Fig. 2 is the cutaway view of the vertical high-pressure heater hydroecium of the utility model along axis;
Fig. 3 is that the A-A of Fig. 2 is to cutaway view.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Referring to Fig. 1-Fig. 3, a kind of embodiment of vertical high-pressure heater, mainly by housing 1, heat-exchanging tube bundle 2 and hydroecium 3 are formed, hydroecium 3 comprises cylindrical shell 4, feed-water inlet 5, self-seal device 6, turnbuckle 7, top cover 9, drainpipe 10, pass partition 11 and blast pipe 13, difference with the prior art is: the heat exchanger tube upper horizontal near the feed-water inlet place in the hydroecium 3 is provided with a stainless steel cowling panel 12, it is identical with the heat exchanger tube internal diameter to offer diameter on the stainless steel cowling panel 12, quantity and heat exchanger tube be aperture one to one, and the center of each aperture and corresponding heat exchanger tube mouth of pipe center are on same vertical line.Have a through hole on the described top cover 9, the self-seal device 6 of through hole below is provided with lifting suspension ring 8.
In actual use, feedwater enters hydroecium 3 by feed-water inlet 5, is assigned to then and carries out heat exchange in the heat exchanger tube in the heat-exchanging tube bundle 2.Feedwater enters hydroecium 3 after the aperture on the stainless steel cowling panel 12 directly enters heat exchanger tube, and the pipe joint place is blocked by stainless steel cowling panel 12, can avoid the direct impact of being fed water.The utility model is simple in structure, realizes easily, has reduced the impact of pipe joint effectively, has reduced the plugging rate of heat exchanger tube, has improved the security and the reliability of high-pressure heater operation.
The weight ratio of hydroecium self-seal device 6 is bigger, when installing and overhaul, all has bigger difficulty.The utility model is being installed and during maintenance, can be earlier hangs suspension ring 8 from the tapping of top cover 9, and self-seal device 6 is mentioned together with top cover 9, and then mount and dismount, operation is very easy, and this has improved the efficient of installing and overhauling effectively, saved the cost of installing and overhauling.
Because the pressure of hydroecium 3 is very high, the weld seam of blast pipe 13 welds of hydroecium 3 is required quite high, if welding is improper, just can cause leakage.And the emplacement type of prior art is taken over and the welding of hydroecium cylindrical shell 4, and welding operation difficulty, weld strength are difficult to guarantee.The utility model adopts the spigot-and-socket welding, blast pipe 13 is inserted cylindrical shell 4 weld, and this weakens the stressed of weld seam greatly.Stop the leakage hidden danger of weld seam herein, improved the efficient of high-pressure heater.
Certainly, above-mentioned explanation is not to be to restriction of the present utility model, and the utility model also is not limited to above-mentioned giving an example.Those skilled in the art are in essential scope of the present utility model, and the variation of making, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
