Due to the special construction of dry reactor, its body (being coil) mainly relies on self cooling mode to dispel the heat, dissipation of heat dry reactor body being produced by cross-ventilation is gone out, if body heat radiation is bad, to directly affect the life-span of dry reactor body insulation, and then the safe operation that jeopardizes dry reactor.
After dry reactor puts into operation, can run on outdoor environment always, therefore the natural conditions such as rainwater, dust storm and birds will inevitably exert an influence to reactor, in order to prevent acid rain, to enter dry reactor coil inside with conductivity contaminated liquid such as the rainwater of dust; In order to reduce the noise of dry reactor, generally all install rain cover additional in coil outside, rain cover is generally made up of top cover, main body, top noise absorption cover, middle part coaming plate and bottom noise absorption cover five parts, as shown in Figure 1 simultaneously.
Above-mentioned rain cover structure, can effectively prevent acid rain, enter after dry reactor coil inside with rainwater of dust etc., and portion brings out the danger of partial discharge in coil; Also can reduce the noise that dry reactor produces.But install additional after the rain cover of this structure, the radiating effect of dry reactor body must be subject to certain impact, as can see from Figure 1, the heat that dry reactor body produces is not too desirable from the radiating effect of rain cover body rim.
Utility model content
The purpose of this utility model is to overcome the shortcoming existing in above-mentioned prior art, and a kind of good heat dissipation effect is provided, the rain cover of the dry reactor of security of operation.
For achieving the above object, the utility model is by the following technical solutions:
A kind of rain cover of dry reactor, be followed successively by rain cover top cover, rain cover main body, top noise absorption cover, middle coaming plate from top to bottom, and bottom noise absorption cover, described top noise absorption cover, middle coaming plate, and the space of bottom noise absorption cover formation hollow holds for dry reactor, place, the bottom plane of described rain cover main body is at least positioned at same plane with noise absorption cover place, top plane, in described rain cover main body, offers heat dissipating grid.
Described rain cover main body comprises body and overlays on the shell of body top, described body and shell all at least comprise the horizontal part of level and the arm to downward-extension respectively from two ends of horizontal part, the upper end of the bottom of described body arm and top noise absorption cover is without alternating share and have certain distance, the arm length of described shell is greater than the arm length of body, and described heat dissipating grid is opened in the arm of shell.
There is staggered part in described shell and top noise absorption cover.
The main body of described rain cover is provided with denoising device.
Described heat dissipating grid is arranged on the part that there is no denoising device.
Between described rain cover top cover and rain cover main body, leave certain space, heat space between rain cover top cover and rain cover main body after the through hole of rain cover main center sheds that reactor produces sheds to both sides.
Compared with prior art, the utlity model has following beneficial effect: place, the bottom plane of the utility model rain cover main body and noise absorption cover place, top plane are positioned at same plane, guarantee acid rain, entered the risk of dry reactor coil inside with rainwater of dust etc., simultaneously, in rain cover main body, offer heat dissipating grid, like this, the heat that reactor produces sheds from heat dissipating grid, convenient heat radiation.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
The technical scheme that the utility model device adopts is: improve the structure of the main body extension of existing rain cover, shorten the height of the denoising device of main body extension, the height of elongated body shell increases heat dissipating grid simultaneously in main body extension.Concrete enforcement is:
One, by calculating and engineering experience, suitably shorten the height of denoising device 8 in rain cover main body 2 extensions.See Fig. 2.
Two, shorten after the height of denoising device 8 in rain cover main body 2 extensions, reduce one barrier of reactor body heat emission path, now, in order better to prevent the impacts of natural conditions on dry reactor coil such as rainwater, dust storm and birds, the shell of main body extension 7 is suitably increased to height.See Fig. 3.
Three, on the shell 7 of main body extension, (part of denoising device not being installed) increases heat dissipating grid, has eliminated last one barrier of dry reactor body heat emission path.See Fig. 4 and Fig. 5.
Specifically, the utility model rain cover, be followed successively by rain cover top cover, rain cover main body, top noise absorption cover, middle coaming plate from top to bottom, and bottom noise absorption cover, described top noise absorption cover, middle coaming plate, and bottom noise absorption cover forms the space of hollow and hold for dry reactor, place, the bottom plane of described rain cover main body is at least positioned at same plane with noise absorption cover place, top plane, in described rain cover main body, offers heat dissipating grid 71.
Described rain cover main body comprises body and overlays on the shell 7 of body top, described body and shell all at least comprise the horizontal part of level and the arm to downward-extension respectively from two ends of horizontal part, the upper end of the bottom of described body arm and top noise absorption cover is without alternating share and have certain distance, the arm length of described shell is greater than the arm length of body, and described heat dissipating grid is opened in the arm of shell.In order to realize the utility model object, can there is staggered part in described shell and top noise absorption cover.
Between described rain cover top cover and rain cover main body, leave certain space, heat space between rain cover top cover and rain cover main body after the through hole of rain cover main center sheds that reactor produces sheds to both sides.
