Technical Field
The utility model relates to a suction dryer field, in particular to an air inlet flow guide device for suction dryer adsorption tower.
Background
The adsorption dryer (suction dryer for short) utilizes the difference of moisture and air molecular volume of saturated compressed air, adopts a special molecular sieve for gas purification to filter saturated water vapor in the compressed air, adsorbs water molecules in molecular sieve particles, and then utilizes a regeneration method to reduce the molecular sieve so as to reduce the pressure dew point of the compressed air and produce high-quality compressed air for a rear-end production site. The absorption dryer adopts a double-tower structure, one tower is used for adsorption, the other tower is used for regeneration (the other tower is used for drying by using a drying air source after adsorption), and the two towers work circularly.
The intermediate molecular sieve is a kind of artificially synthesized hydrated aluminosilicate (zeolite) or natural zeolite with the function of screening molecules, and has high adsorption capacity, high selectivity and high temperature resistance. It is widely used in organic chemical industry and petrochemical industry. As an industrial body of a dryer, the adsorbent is subjected to frequent impacts of pressure, moisture and heat for most of the time, and is easily broken mechanically and contaminated by a medium, deteriorating the performance of the adsorbent.
As shown in fig. 1, the design structure of the existing adsorption (regeneration) tower of the suction dryer is that compressed air directly enters the adsorption tower 1 through an air inlet pipe 3, the compressed air with certain flow rate and pressure directly contacts with the molecular sieve 2 along the air inlet, the contact range is not comprehensive enough, not all the molecular sieves 2 can participate in the adsorption of moisture, and meanwhile, the molecular sieves which are directly and frequently impacted by the flow rate and the pressure are easy to crack and pulverize, and the service life of the molecular sieves is shortened.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the air inlet guide device for the adsorption tower of the suction dryer is used for improving the adsorption effect of the adsorption tower.
In order to solve the above problem, the utility model adopts the following technical scheme: the air inlet guide device for the adsorption tower of the suction dryer comprises a first flange, a second flange, a first guide cone, a second guide cone and an air flow diffusion device, wherein the first flange is used for being connected with an air inlet pipeline of the adsorption tower, and the second flange is used for being connected with an air inlet of the adsorption tower; the first flange is communicated with the second flange through the first diversion cone, and the second flange is communicated with the airflow diffusion device through the second diversion cone.
