Description
Technical field
The present invention relates to normally used environmental protection denitration non-metal compensator in the pipelines such as ventilation, dedusting, smoke evacuation and equipment, belong to the environment-friendly engineering technical field.
Background technique
In industrial production, for example in manufacture of cement, along with the requirement of country for energy-saving and emission-reduction, the discharge that reduces oxynitrides is imperative, thereby relates to the denitration problem of raw material.
Non-metal compensator is widely used in Iron And Steel Plant, smelter, petrochemical plant, the exhaust gas desulfurizations such as thermal power plant, cement plant and atomic power power plant, dusting apparatus, air heating, help the place, gateway of equipment such as stream air blast etc., its performance is better than stainless steel telescopic joint greatly, has good combination property.The elastic element of its operative body is non-metallic material, and fabric normally, so claim again fabric compensator (expansion joint, slip joint).In the situation that environment protection desulphurization, flue-gas temperature reaches 200 ℃ usually, but in the situation that environmental protection denitration, ambient temperature can reach 400-500 ℃, cause the device structure amount of deformation to increase, radial displacement is larger, and the displacement and the stress that therefore cause can not be absorbed and be digested by the structure of original non-metal compensator, thereby cause stabilization of equipment performance to descend, reduce working life.Therefore, need a kind of novel non-metal compensator to meet the application in environmental protection denitration situation.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art part, a kind of environmental protection denitration non-metal compensator is provided.

Embodiment
Below in conjunction with accompanying drawing, describe the present invention in detail.Should be appreciated that, accompanying drawing be only mode with example the present invention will be described, and should not be considered as protection scope of the present invention is construed as limiting, protection scope of the present invention should be limited by claims only.
As Fig. 1, shown in 2 and 3, environmental protection denitration non-metal compensator of the present invention, comprise frame, take over (1), honeycomb duct (3), covering and flue (8), described frame comprises forebay and rear bay, described baffle plate comprises front screen and backboard, described flue (8) comprises front flue and rear pass, before described, backboard is respectively with front, rear bay is connected, and backboard is located at the front screen periphery, and both are spaced apart, before, between backboard, connect by multilayer Stainless Steel Cloth (10), fastening and the sealing with press strip (9) between described Stainless Steel Cloth (10) and baffle plate, before described, rear bay is respectively with front, rear pass (8) connects, described baffle plate and frame be inboard to be connected and to enclose formation honeycomb duct (3), described covering is fixed on frame by screw (6) and press strip (2), described frame and flue (8) load partially connect, there is radial offset in the frame namely be connected with front end smoke canal with the frame be connected with the rear end flue, described covering is composite silicone rubber coated glass fiber cloth (5).Because the environment of environmental protection denitration non-metal compensator application of the present invention is comparatively harsh, the product displacement amount is large, so can not only adopt the non-metal compensator of prior art.The non-metal compensator of prior art is being in after installation on same straight line, and environmental protection denitration non-metal compensator of the present invention has certain inclined to one side dress effect after installation, can absorb better stress, digest better displacement, thereby increased the installation stability of equipment, the working life of extension device.
In described environmental protection denitration non-metal compensator, described composite silicone rubber coated glass fiber cloth (5) is 8 layers of composite structure, is followed successively by from outside to inside 304 Stainless Steel Cloth string diameter nets (5-1), 304 Stainless Steel Cloth string diameter nets (5-2), fluorine rubber cloth (5-3), silicone rubber glass fibre cloth (5-4), teflon cloth (5-5), glass fibre cloth (5-6), alumina silicate blanket (5-7) and alkali-free glass fiber cloth (5-8).
Described composite silicone rubber coated glass fiber cloth (5), the thickness of each layer is respectively: 304 Stainless Steel Cloth string diameter nets (5-1) are that 0.2 millimeter, 304 Stainless Steel Cloth string diameter nets (5-2) are that 0.2 millimeter, fluorine rubber cloth (5-3) are that 1.2 millimeters, silicone rubber glass fibre cloth (5-4) are that 1.2 millimeters, teflon cloth (5-5) are that 0.25 millimeter, glass fibre cloth (5-6) are that 0.8 millimeter, alumina silicate blanket (5-7) are that 20 millimeters, alkali-free glass fiber cloth (5-8) are 1.2 millimeters.
Between described frame and flue (8), is connected by taking over (1), frame is to be to take over configuration and be connected with flue, thereby easily solves sealing problem, the Environmental Conditions of applicable large-scale equipment.
Between the two ends of described adapter (1), be connected with gusset (7), strengthen and protective action to provide.
Between described covering and honeycomb duct (3), also be provided with aluminum silicate fiber Covered with Angles silk screen (4), play the reinforcement structure, protect covering and heat insulation effect, thereby increased the working life of covering and whole equipment.
Covering is the main telescopic body of non-metal compensator, and it is that do as one likes can good composite silicone rubber coated glass fiber cloth (5) be made, and is a kind of high-intensity sealing material, and its effect is to absorb swell increment, prevents from leaking gas and the seepage of rainwater.The present invention has adopted the composite silicone rubber coated glass fiber cloth of 8 layers of composite structure especially, and between covering and honeycomb duct 3, also is provided with aluminum silicate fiber Covered with Angles silk screen 4 and plays reinforing function.Covering 5 and the mode that adopts screw 6 to add press strip 2 that is connected of taking over 1.Press strip 2 rounds and plays seal action.
Frame is the profile support of non-metal compensator, ensures enough strength and stiffness, and frame has two kinds with the Placement of flue 8: flange is connected with taking over and is connected.In the present invention, consider for steadiness and sealing, adopted 1 the form of taking over.Two ends taking over, increased a gusset 7, strengthens and protect for the structure to frame.Frame of the present invention connects the form of the inclined to one side dress adopted, and there is radial offset in the frame namely be connected with front end smoke canal with the frame be connected with the rear end flue, as shown in Figure 3, thereby can absorb better distortion and the stress that radial displacement brings.
Baffle plate has been the effect of water conservancy diversion and protection thermal-protective coating.In the present invention, baffle plate rounds and forms honeycomb duct 3, promotes smoke evacuation to be undertaken by predetermined direction.
Environmental protection denitration non-metal compensator of the present invention mainly is applicable to the gas exhaust duct that radial displacement is larger.Because some requirements for pipes is higher, environment is more special, adopts compensator of the present invention can effectively compensate the distortion that radial displacement brings.
The above is described in detail embodiments of the present invention by reference to the accompanying drawings, but the invention is not restricted to above-mentioned mode of execution, in the ken that affiliated technical field those of ordinary skill possesses, can also under the prerequisite that does not break away from aim of the present invention, make a variety of changes.
