Abstract
The utility model discloses a corrosion resistance compensator for a chemical exhaust gas discharge system. The corrosion resistance compensator comprises end connecting pipes, a corrugated pipe, a honeycomb duct and a middle connecting pipe, wherein the middle connecting pipe is connected with the end connecting pipes at two ends through the corrugated pipe, so as to form a combined corrugated pipe compensation structure; the honeycomb duct for axially covering the corrugated pipe is arranged inside the corrugated pipe; the corrugated pipe is formed by a stainless steel plate; composite corrosion resistant layers are arranged at the inner surfaces of the end connecting pipes, the corrugated pipe, the honeycomb duct and the middle connecting pipe. The further improvement is that each composite corrosion resistant layer is a polytetrafluoroethylene composite coating; the corrugated pipe is pressed and molded by a plurality of layers of thin sheets; the end connecting pipes, the honeycomb duct and the middle connecting pipe are made of stainless steel. The corrosion resistance compensator has higher decay resistance, and is long in service life and low in use cost.
Description
Technical field
The utility model relates to a kind of pipe safety device, and specifically, the utility model relates to a kind of chemical industry tail gas releasing system compensator.
Background technique
The displacement producing in the alignment error of general use metal compensator bucking-out system and running in chemical industry tail gas releasing system.The adapter of the metal compensator of the prior art of using in chemical industry tail gas releasing system, honeycomb duct generally adopt low carbon steel or low alloy steel to make, because chemical industry tail gas generally all has stronger corrosivity, therefore, adapter, the honeycomb duct of the metal compensator using in chemical industry tail gas releasing system generally lost efficacy because of corrosion than being easier to, therefore, metal compensator is shorter working life, and user cost is higher.
Summary of the invention
The utility model is for the deficiencies in the prior art, proposes a kind ofly can solve adapter, the perishable Problem of Failure of honeycomb duct, thus significant prolongation metal compensator working life, the corrosion-resistant compensator of chemical industry tail gas releasing system of reduction user cost.
The utility model is achieved through the following technical solutions technical goal.
The corrosion-resistant compensator of chemical industry tail gas releasing system, comprises pipe nipple, bellows, honeycomb duct, middle adapter, between described middle adapter and two ends pipe nipple, by bellows, is connected, and forms Combined corrugated pipe collocation structure; In described bellows, be provided with the honeycomb duct of axial covering bellows; Described bellows is made by corrosion resistant plate; Its improvements are: described pipe nipple, bellows, honeycomb duct, middle adapter internal surface are provided with composite anticorrosive layer.
In said structure, described composite anticorrosive layer is Teflon Composite Coating.
In said structure, described bellows is that multi-layered sheet is compressing.
In said structure, the material of described bellows is 1Cr18Ni9Ti.
In said structure, described pipe nipple, honeycomb duct, middle adapter are made by stainless steel.
In said structure, the material of described pipe nipple, middle adapter is 0Cr18Ni9.
The utility model compared with prior art, has following good effect:
1. pipe nipple, bellows, honeycomb duct, middle adapter internal surface are provided with composite anticorrosive layer, make pipe nipple, bellows, honeycomb duct, middle adapter all there is higher decay resistance, thereby significant prolongation metal compensator working life, reduce user cost.
2. bellows is that multi-layered sheet is compressing, has effectively improved the intensity of bellows.
3. pipe nipple, honeycomb duct, middle adapter are made by stainless steel, have further improved the decay resistance of pipe nipple, honeycomb duct, middle adapter, thereby further extend metal compensator working life, reduce user cost.
4.0Cr18Ni9 has good corrosion resistance, heat resistance, has further improved the corrosion resistance of compensator, has improved the working life of metal compensator.
