Description
Technical field
The utility model belongs to refining equipment or device technique field, is specifically related to the equipment filtered the air entered.
Background technology
4 charge doors are arranged at the top of establishing of KDN-800/60Y air separation unit purification system adsorption tanks, and a discharge port is arranged at bottom, and these adsorption tanks exist inner part maintenance difficulty, the molecular sieve filling shortcoming such as not easily.
This adsorption tanks inner part mainly air into and out of separation net, the effect of separation net be do not hinder air into and out of prerequisite under, effectively stop adsorbent of molecular sieve to run and damage.If separation net is damaged, adsorbent enters air separation column with raw material, and gently then device is stopped work, and heavy then air separation plant is damaged.Reference line is operating experience in the industry, and the service life of separation net is about 3-5.
Because these adsorption tanks do not arrange manhole, when overhaul of the equipments, check that separation net is difficult to the breakage finding that separation net is trickle by means of only discharge port, and it is just more difficult to change separation net.
These adsorption tanks filling raw material adds agent mouth by 4 of top and joins in absorption tank body, and the speed of filling raw material is slow.Because filling raw material process is not visible, probably cause adsorbent loading density skewness, after putting equipment in service, raw material drives adsorbent redistribution, forms larger space, very easily causes adsorbent broken, even efflorescence.
Summary of the invention
Technical problem to be solved in the utility model is to overcome above-mentioned KDN-800/60Y air separation unit purification system adsorption tanks internal overhaul difficulty, molecular sieve dress shortcoming not easily, provides that a kind of adsorbent successively loads, even density, adds the purified air adsorption tanks of the air separation unit of agent time short, easy access.
The adopted technical scheme that solves the problem is: be provided with admission line in tank base, import separation net is provided with bottom tank interior, tank body right flank is provided with discharge port, tank body top flange dish is processed with manhole and is provided with feeding cover, the exit of tank body is provided with end and passes the outlet that feeding cover and discharge duct be connected and isolate bucket, and the tank body space between outlet isolation bucket and import separation net is filled with adsorbent of molecular sieve.
The model of adsorbent of molecular sieve of the present utility model is 13X type.
Because the utility model adopts, outlet isolation bucket is set in the exit of tank body, tank body space between outlet isolation bucket and import separation net is filled with 13X type molecular sieve, the water in raw air sloughed by 13X type molecular sieve, the impurity such as carbon dioxide and a small amount of hydro carbons, outlet isolation bucket is for avoiding the blocking of pipeline, outlet isolation bucket and discharge duct are connected, air up to standard through adsorption filtration in tank body enters downstream process system by discharge duct, open feeding cover and add adsorbent by the manhole at top to the tank body space between the outlet isolation bucket and import separation net of tank interior.The utility model shortens single tank and adds the agent time, handled easily personnel enter maintenance and the replacing that tank interior carries out import separation net simultaneously, when occurring that adsorbent of molecular sieve is uneven, adjust in time, successfully solve parts maintenance difficulty in tank body, molecular sieve loads not easily, the damaged technical problem needing to change in time of adsorbent.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment 1.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described, but the utility model is not limited to these embodiments.
Embodiment 1
In FIG, the purified air adsorption tanks of the air separation unit of the present embodiment are made up of tank body 1, outlet isolation bucket 2, feeding cover 3, discharge duct 4, discharge port 5, import separation net 6, admission line 7, adsorbent of molecular sieve 8 connection.
Admission line 7 is connected with at tank body 1 bottom welding, air enters from admission line 7, be evenly distributed on bottom space, be fixedly connected at tank body 1 interior bottom portion screw threads for fastening connector and import separation net 6 is installed, tank body 1 top flange is processed with manhole, manhole top is installed with feeding cover 3 by flange threaded fastener, the upper end of outlet isolation bucket 2 is connected by flange screw threads for fastening connector and discharge duct 4 through feeding cover 3, adsorbent of molecular sieve 8 is loaded in import separation net 6 and the outlet tank body space isolated between bucket 2, the model of adsorbent of molecular sieve 8 is 13X type, gas is from bottom to top by adsorbent of molecular sieve 8, water in deaerated, carbon dioxide and a small amount of hydrocarbon impurities, the effect of outlet isolation bucket 2 prevents adsorbent of molecular sieve 8 from entering discharge duct 4, the air separation plant of clog downstream, open feeding cover 3 and add adsorbent of molecular sieve 8 by manhole to the tank body space between the outlet isolation bucket 2 and import separation net 6 of tank body 1 inside, single tank can be shortened and add the agent time, handled easily personnel enter maintenance and the replacing that tank interior carries out import separation net 6 simultaneously, Timeliness coverage when occurring that adsorbent of molecular sieve 8 is uneven also adjusts.Air up to standard through adsorption filtration in tank body 1 enters next stage operating system by discharge duct 4, discharge port 5 is had at tank body 1 right side wall weld connection, the residue raffinate be used in evacuation tank body, also can carry out inspection by discharge port 5 pairs of import separation nets 6 and change.
Operation principle of the present utility model is as follows:
The air of tank body 1 inside is entered by admission line 7, the adsorbent of molecular sieve 8 loaded in tank body space between bucket 2 is isolated through import separation net 6 and outlet, utilize its adsorption function to the moisture in air, carbon dioxide and a small amount of hydrocarbon impurities purify, purify up to standard after air by outlet isolation bucket 2, enter discharge duct 4 and enter downstream process system, air is separated out without solid in the ice chest of-170 DEG C, the ice of pipeline is avoided to block up, open feeding cover 3 and add adsorbent of molecular sieve 8 by the manhole at top to the outlet isolation bucket 2 in tank body 1 and the tank body space between import separation net 6, single tank can be shortened and add the agent time, handled easily personnel enter in tank body 1 and overhaul import separation net 6 and change simultaneously, Timeliness coverage when occurring that adsorbent of molecular sieve 8 is uneven also adjusts.
