Technical field:
The present invention relates to a kind of devices of adsorption vehicle tail gas molecular sieve, belong to technical field of new material preparation.
Background technique:
Molecular sieve is a kind of alumino-silicate compound with cubic lattice, mainly forms sky by oxygen bridge connection by sial
Spacious skeleton structure has the uniform duct in many apertures and the very big hole of marshalling, internal surface area in the structure.Molecular sieve
Adsorbent is widely used in petroleum because of excellent properties such as its unique crystal structure, high surface area, adsorptivity and catalytics
The numerous areas such as chemical industry, environmental protection, new material, biological medicine, also therefore the application of adsorbent of molecular sieve has huge warp
Benefit of helping and important application value.
Due to containing a large amount of pernicious gas, CO, HC, NOx, leaded object and sulphur in waste gas sent off from automobiles in vehicle exhaust
The ingredients such as compound are done great harm to human body.If be directly discharged into air, it will cause atmosphere pollution and seriously affect people's
Health, it is existing general using automobile exhaust purification equipment, atmosphere, common molecule are discharged into again later to purifying vehicle exhaust
Sieve still, contains some hydrones, affects the normal of molecular sieve as the preferable absorbent of vehicle exhaust in vehicle exhaust
Absorption function, so that the absorption burned gas ratio of molecular sieve declines.
Summary of the invention
The purpose of the present invention is providing a kind of device of adsorption vehicle tail gas molecular sieve in view of the above problems, use
When molecular sieve carries out absorption cleaning to vehicle exhaust, influence of the hydrone to molecular sieve absorption function, absorption efficiency are avoided
Height, purification are thorough.
Above-mentioned purpose is achieved through the following technical solutions:
The device of adsorption vehicle tail gas molecular sieve, including the shell being connect with vehicle exhaust exhaust tube, the shell
One end is provided with jointing, and the other end is provided with purification gas discharge drum, and the shell the inside is from close to the one of connector
End is disposed with catalytic converter, Water Molecular Adsorption device, molecular sieve adsorbent equipment.
The device of the adsorption vehicle tail gas molecular sieve, the catalytic converter include metal-back cabinet, ceramic honey comb
With damping heat insulating mattress, it is provided with air inlet and air outlet on the metal-back cabinet, passes through damping inside the metal-back cabinet
