Abstract
The utility model belongs to heating equipment, and particularly discloses an energy-saving anti-blockage steam air heater. The energy-saving anti-blockage steam air heater comprises a heat transmission tube bundle, a steam collecting tank and a water collecting tank, wherein the steam collecting tank and the water collecting tank are communicated with the heat transmission tube bundle and respectively mounted at two ends of the heat transmission tube, the steam collecting tank is connected with a steam inlet tube, and the water collecting tank is connected with a water drain tube. The energy-saving anti-blockage steam air heater is characterized in that a self-stabilizing structure is rotatably connected between the steam collecting tank and the water collecting tank, the heat transmission tube bundle adopts the steam inlet tube and the water drain tube as rotating shafts, the steam inlet tube and the water drain tube are provided with rotary joints connected with the steam inlet tube and the water drain tube, each rotary joint comprises an outer casing and an inner casing which are connected with each other through a graphite ring, and draw bars are arranged on the periphery of the outer casing. The energy-saving anti-blockage steam air heater can effectively stop dust blockage, weld joint cracking and tube leakage, and when the steam air heater is not used, resistance in a duct is minimized, thereby reducing consumption of electric power.
Description
(1) technical field
The utility model belongs to heat power equipment, particularly a kind of energy-conservation block-proof type steam air heater.
(2) background technology
Steam air heater be northern thermal power plant the auxiliary equipment that must use.Steam air heater had only about 90 days in its running time in 1 year, but between lay-off period, steam air heater still places the air channel, the boiler air-supply still will be passed through steam air heater, pressure fan expends a large amount of electric energy and makes idle work, because the fin tube structure densification of steam air heater, tube pitch is too little, flowing resistance is big, thereby mostly there is more serious clogging phenomenon in domestic steam air heater, can't carry out on-line cleaning behind the stifled ash of steam air heater, can only wait long unit outage chance, not only use the blower fan power consumption skyrocketing, and cause the burner hearth air-supply not enough when serious, even be forced to the load down operation, also exist because phenomenons such as weld cracking that the thermal expansion inequality causes and tube leaks in addition.
Chinese patent 9822036705 has provided a kind of rotatable steam air heater, and it is intended to make steam air heater to revolve to turn 90 degrees, and eliminates the resistance that steam air heater produces when not working.Its structure includes rotating actuator and heat transfer tube group.The two ends of heat transfer tube group have the collection case in addition in parallel and be fixed on the rotation transmission axis respectively, and rotating actuator is finished 90 degree rotations by a connecting rod axis.But this steam air heater that revolves is not suitable for safe and reliable rotation under the spinning obstacle that brings thus at the heat-transfer pipe gravity deformation, is not suitable under the boiler room environment yet, safe and reliable rotation under the hot and cold conditions of steam air heater.
(3) summary of the invention
The utility model provides a kind of energy-conservation block-proof type steam air heater simple in structure, easy to use in order to remedy the deficiencies in the prior art.
The utility model is achieved by the following technical solution:
A kind of energy-conservation block-proof type steam air heater, comprise heating surface bank and be communicated with steam manifold and the header tank that heating surface bank also is installed in its two ends respectively, steam manifold is connected with steam inlet pipe, header tank is connected with drain pipe, it is characterized in that: the rotatable self-stabilization structure that is connected with in the middle of described steam manifold and the header tank, heating surface bank is a rotating shaft with steam inlet pipe and drain pipe, and steam inlet pipe and drain pipe are provided with connected swivel joint, swivel joint comprises shell body and the inner housing that connects by graphite annulus, and the shell body outside is arranged with pull bar.
Heating surface bank is to have the parallel layering of several isodiametric pipes uniform, heat-transfer pipe is by self-stabilization structure firm support in addition, heating surface bank is the rotating shaft rotation with steam inlet pipe and drain pipe, reduce the resistance that produces when steam air heater is not worked, swivel joint reaches the purpose of sealing by being tightly connected of inner housing and shell body, can guarantee that band presses steam not leak in the heat-transfer pipe.
More excellent scheme of the present utility model is:
All being venetian blind type between described heating surface bank and steam inlet pipe and the drain pipe is rotatably connected.Heating surface bank becomes sparse arrangement, and spacing of fin, horizontal spacing, longitudinal pitch increase, and from the problem that has solved the stifled ash of tube bank basically and blocked foreign material, thereby eliminates the phenomenon that steam air heater run duration resistance increases, consumes the motor electric energy rapidly.
Described steam air heater is equipped with the proprietary structure of dual thermal expansion self-absorption, can prevent the steam air heater tube leak and snap.
Described swivel joint is connected with electronic rocker-arm drive mechanism, with it as rotary power.
The utility model can effectively prevent the stifled ash of steam air heater, weld cracking and tube leak, in steam air heater time spent not, the resistance that places the air channel to produce is dropped to minimum, reduces expending of electric energy.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model swivel joint.
Among the figure, 1 swivel joint, 2 self-stabilization structures, 3 heating surface banks, 4 steam manifolds, 5 steam inlet pipes, 6 header tanks, 7 drain pipes, 8 shell bodies, 9 graphite annulus, 10 pull bars, 11 inner housings.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises heating surface bank 3 and is communicated with steam manifold 4 and the header tank 6 that heating surface bank 3 also is installed in its two ends respectively, steam manifold 4 is connected with steam inlet pipe 5, header tank 6 is connected with drain pipe 7, the rotatable self-stabilization structure 2 that is connected with in the middle of described steam manifold 4 and the header tank 6, heating surface bank 3 is a rotating shaft with steam inlet pipe 5 and drain pipe 7, and steam inlet pipe 5 and drain pipe 7 are provided with connected swivel joint 1, swivel joint 1 comprises shell body 8 and the inner housing 11 that connects by graphite annulus 9, and shell body 8 outsides are arranged with pull bar 10; All being venetian blind type between described heating surface bank 3 and steam inlet pipe 5 and the drain pipe 7 is rotatably connected; Described steam air heater is equipped with the proprietary structure of dual thermal expansion self-absorption; Described swivel joint 1 is connected with electronic rocker-arm drive mechanism.
During the utility model work, heating surface bank 3 sealing air channels, swivel joint 1 carries out the strictness sealing to it, has improved the temperature that enters air preheater gas; When not working, by self-stabilization structure 2 in addition the heating surface bank 3 of firm support be that rotating shaft revolves and turn 90 degrees with steam inlet pipe 5 and drain pipe 7, the air channel is opened, thereby reduces the resistance that produces when not working; In season in spring and autumn, heating surface bank 3 is carried out partial rotation, make its incomplete folding, reach the purpose of air passage portion admission.
