Description

A kind of tubing for toxic gas transport
Technical field
The present invention relates to field of environment protection equipment, and in particular to a kind of tubing for toxic gas transport.
Background technique
Currently, either life exhaust gas or indusrial toxic gas requires after purified treatment, it can just be thrown into atmosphere In.The transport of toxic gas generallys use transport pipeline and is conveyed or discharged, since there are a large amount of corrosivity in toxic gas Substance, therefore pipeline, after long-time conveys toxic gas, inner wall is easy to be corroded, and influences the service life of pipeline.
Summary of the invention
In order to solve the above-mentioned technical problem, the present invention discloses a kind of tubing for toxic gas transport, the pipeline corrosion resistant Corrosion is strong, effectively avoids the corrosive substance corrosion pipeline in toxic gas, can be obviously improved the service life of itself.
The present invention is achieved through the following technical solutions:
A kind of tubing for toxic gas transport, including tube body, inboard wall of tube body is coated with one layer of anti-corrosion layer, in tube body Inner wall is equipped with several wear-resisting protrusions, and the wear-resisting protrusion top surface passes through anti-corrosion layer and is placed in tube cavity, is equipped in tube wall Protective layer, the tube body are specially pipe of cement, and the protective layer is specially polymer cement-base waterproof coating layer.
In the present invention, tube body uses pipe of cement, has enough intensity and corrosion resistant erosion degree, protective layer is for protecting pipe of cement Outer wall is avoided by rain erosion after pipe of cement long-time use, and anti-corrosion layer avoids in pipe of cement for protecting cement inside pipe wall Wall is directly contacted with toxic gas and is corroded, and anti-corrosion layer itself has high corrosion resistance, can be obviously improved tubing Service life, the wear-resisting protrusion of inboard wall of tube body setting, can reduce abrasion of the particulate matter to anti-corrosion layer in toxic gas, into The service life of one step raising tubing.
The wear-resisting protrusion is hemispheric ceramic protrusion, and the diameter of ceramic protrusion is 3-6mm, two neighboring wear-resisting protrusion Between distance be wear-resisting protrusion diameter half.
The tube wall with a thickness of 10-30mm, the anti-corrosion layer is with a thickness of 1-3mm.
The anti-corrosion layer is made up of the component of following mass fraction: 20-28 parts of deionized water, epoxy resin 20-32 Part, gluey 0.8-2.4 parts of molybdenum disulfide, 10-18 parts of silica flour, 12-16 parts of sodium citrate, 6-12 parts of mica powder, talcum powder 6- 14 parts, 0.5-1.0 parts of thickener, 1.0-2.0 parts of isothiazolinone derivatives, 0.1-0.2 parts of dispersing agent, 4-6 parts of diatomite.
The thickener is polyethylene glycol oxide or methylcellulose, and the dispersing agent is poly.
In the present invention, anti-corrosion layer is made of nontoxic and pollution-free component, therefore its own will not make toxic gas At secondary pollution, epoxy resin, silica flour, the mica powder added in component can effectively promote wearability, and pipeline is avoided to use It is worn in the process by the impurity particle in toxic gas, isothiazolinone derivatives can greatly promote corrosion resistance, avoid Poisonous gas discharge tube is damaged by the corrosive substance in toxic gas, is obviously improved the service life of pipeline.
Compared with prior art, the present invention having the following advantages and benefits:
A kind of tubing for toxic gas transport of the present invention, tube body use pipe of cement, have enough intensity and corrosion resistant Erosion degree, protective layer avoid after pipe of cement long-time use by rain erosion, anti-corrosion layer is for protecting for protecting cement pipe outer wall Cement inside pipe wall is protected, cement inside pipe wall is avoided directly to contact and be corroded with toxic gas, anti-corrosion layer itself has high resistance to Corrosivity, can be obviously improved the service life of tubing, the wear-resisting protrusion of inboard wall of tube body setting, can reduce in toxic gas Abrasion of the grain substance to anti-corrosion layer, further increases the service life of tubing.
