Description
Technical field
The present invention relates to a kind of exhaust recovery device, be specifically related to a kind of exhaust recovery device of rotating film type thermal deaerator.
Background technology
In rotating film type thermal deaerator oxygen removal process, first condensate water and supplementing water enter a deoxygenation inward turning film device group hydroecium of oxygen-eliminating device, under certain differential pressure of water level from the oblique churning of aperture of film pipe to endoporus, form jet, because endoporus has been full of the heating steam of rising, water is just inhaled a large amount of heating steam to involve in jet motion, at the utmost point, in the short time, produce violent Hybrid Heating effect, water temperature increases substantially, and the water of rotation continues backspin along film pipe orifice wall, form the water membrane skirt of one deck rolling, now the heat transfer water mass transfer effect of turbulent condition is the most desirable, the water temperature temperature that reaches capacity, oxygen be separated, because oxygen cannot arbitrarily spread in endoporus, oxygen with the steam rising from blast pipe discharged to atmosphere.Current rotating film type thermal deaerator, after heating deoxygenation, because incondensable gas directly drains into atmosphere by blast pipe, in getting rid of incondensable gas process, exhaust noise is large, a part of steam is also together discharged simultaneously, causes the waste of a part of energy.
Summary of the invention
The technical problem to be solved in the present invention is: the exhaust recovery device that the rotating film type thermal deaerator of a kind of noise reduction, the remaining vapour of recovery is provided.
In order to solve the problems of the technologies described above, the invention provides a kind of exhaust recovery device of rotating film type thermal deaerator, comprise blast pipe and the horizontal water tank being connected with blast pipe, horizontal water tank top is provided with water inlet, and bottom is provided with discharge outlet, and the interior lower end of described horizontal water tank is provided with muffler, muffler one side is fixedly connected with blast pipe, opposite side is fixedly connected with exhaust outlet, is provided with curved cover plate on water inlet, and curved cover plate is provided with negative pressure hole.
Adopt the exhaust recovery device tool of the rotating film type thermal deaerator of technique scheme to have the following advantages: 1, the interior lower end at horizontal water tank is provided with muffler, muffler one side is fixedly connected with blast pipe, opposite side is connected with exhaust outlet, by horizontal water tank and muffler, be assembled into one, the heat of the gas that utilization is discharged from rotating film type thermal deaerator heats the water of water tank the inside through muffler transmission, has effectively utilized the energy of remaining vapour; Sound deadening when 2, muffler plays Exhaust Gas is arranged on the interior lower end of horizontal water tank simultaneously due to muffler, horizontal water tank is that the outside that is wrapped in muffler is formed with certain space, has also played the effect of auxiliary reduction noise; 3, on water inlet, be provided with curved cover plate, when remaining vapour energy is utilized, arc forms larger space, can further prevent that energy runs off from the top of horizontal water tank, the negative pressure hole simultaneously arranging on curved cover plate, can effectively control gas that oxygen-eliminating device the discharges pressure in horizontal water tank, also guarantee the security that remaining vapour energy is reclaimed.
As preferred version, consider and eliminate or reduce by physical impact and shattering zone to the destruction of horizontal water tank, between the lower end of described muffler and horizontal water tank inwall, be provided with 3 ~ 5 cushion pads.
As preferred version, in order to strengthen the fastening effect of cushion pad, described cushion pad and horizontal water tank inwall are welded and fixed.
As preferred version, in order effectively to prevent the loss of energy, described horizontal water tank inwall is provided with one deck alumina silicate or porcelain tendre insulation material.
accompanying drawing explanation
Fig. 1 is the structural representation of the exhaust recovery device of rotating film type thermal deaerator of the present invention;
In figure: 1-blast pipe, 2-horizontal water tank, 3-water inlet, 4-discharge outlet, 5-muffler, 6-exhaust outlet, 7-curved cover plate, 8-negative pressure hole, 9-cushion pad, 10-insulation material, 11-shower tray.
the specific embodiment
Below in conjunction with drawings and Examples, technical solution of the present invention is further illustrated:
As shown in Figure 1, the invention provides a kind of exhaust recovery device of rotating film type thermal deaerator, the horizontal water tank 2 that comprises blast pipe 1 and employing stainless steel, blast pipe 1 is connected with horizontal water tank 2 sidewalls, horizontal water tank 2 tops are provided with water inlet 3, water inlet 3 belows arrange shower tray, bottom is provided with discharge outlet 4, the interior lower end of horizontal water tank 2 is provided with the muffler 5 of the micropunch template of good erasure effect, muffler 5 one sides are fixedly connected with blast pipe 1, opposite side is connected with exhaust outlet 6, on water inlet 3, be provided with curved cover plate 7, curved cover plate 7 is provided with negative pressure hole 8, between the lower end of muffler 5 and horizontal water tank 2 inwalls, be provided with the cushion pad 9 of 3 crashproof glue materials, cushion pad 9 is welded and fixed with horizontal water tank 2 inwalls, horizontal water tank 2 inwalls are provided with one deck alumina silicate or porcelain tendre insulation material 10, when operation, water is injected into horizontal water tank 2 through shower tray 11 from water inlet 3, shower tray can cause larger impulsive force to muffler 5 and horizontal water tank 2 during anti-sealing injection casing, fastening curved cover plate 7 after filling with, when noise reduction is carried out in 5 pairs of exhausts of muffler, the heat of the exhaust of blast pipe 1 that also takes full advantage of oxygen-eliminating device in muffler 5, cyclically to the water heating in horizontal water tank 2, the water heating is recycled by the discharge outlet 6 of horizontal water tank 2 bottoms, the hot water of discharging also can be sent in oxygen-eliminating device and recycle again by pump, saved the energy.In concrete enforcement, for eliminating or reducing the degree by the destruction of physical impact and shattering zone feed-tank, the number of cushion pad 9 also can be chosen as arbitrary value in 3 ~ 5 according to actual conditions.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the premise without departing from the principles of the invention; can also make some distortion and improvement; these also should be considered as protection scope of the present invention, and these can not affect effect of the invention process and practical applicability.
