The skirt is arranged at the bottom of the buffer tank body, the heat tracing coil is arranged in the skirt, the heat preservation function is added to the skirt of the buffer tank, and the problem of recycling deposited liquid at the bottom of the compressor inlet buffer tank can be effectively solved. In winter, when the compressor inlet buffer tank runs, temperature monitoring is conducted at the bottom of the buffer tank for multiple times, and temperature is above 30 DEG C every time, recycling compressor interlocking caused by the deposited liquid of the buffer tank cannot be generated in the whole running process in winter, and practice shows that the implementation effect of the scheme is good. The compressor inlet buffer tank is simple in structure, safe, and easy to operate.
Description
Technical field
The utility model relates to chemical field, is specifically related to a kind of suction port of compressor knock out drum.
Background technique
The 2PE of Plastic Plant of Yang Zi petrochemical industry Co., Ltd device system introduces patented technology--the low-pressure vapor phase method full density polythene technique (Univation technique) of U.S. union carbide corporation (UCC), the ethene of take is comonomer as raw material, butene-1 or hexene-1, hydrogen is chain-transferring agent, adopt patent catalyzer (UCAT-J) or the domestic catalyst (SLC-S, BCS02) of U.S. union carbide corporation (UCC), reactive polymeric in gas-phase fluidized-bed reactor, produces the polyethylene resin of high, medium and low density.Product category has three kinds of injection mouldings, extrusion molding, blowing, is mainly used in the aspects such as film, hollow container, tubing.
The 2PE of Plastic Plant of Yang Zi petrochemical industry Co., Ltd device adopts induction condensation technology, to meet the high load steady production of device, induced condensing agent and a small amount of comonomer enter reclaiming system with gas phase form, by a series of cooling, after compression, with liquid phase form, be recycled again, the nucleus equipment of reclaiming system is a vertical labyrinth compressor of double-action, compressor one-level, secondary is imported and exported and is equipped with knock out drum, winter operation is subject to cold service, in gas phase, part induced condensing agent can produce hydrops in suction port of compressor pipeline and one-level inlet buffer, for equipment protection and stable operation, consider, the following several method of former process using is processed compressor first-level buffer tank hydrops problem:
1, at knock out drum, increase on-the-spot two flange magnetic flap level gauge, convenient outer behaviour patrols and examines timely discovery and hydrops in knock out drum is discharged in time;
2, increase the magnetic float liquidlevel meter that can show for DCS, and high level chain is set, facilitate behaviour's monitoring in control room, and in time to the discharge of knock out drum hydrops, high level chain plays the effect of protection equipment;
3, at knock out drum tank body, increase electrical tracing, make hydrops gasification in knock out drum;
There are the following problems for above 3 kinds of methods:
1, in actual production process, also have a small amount of mineral oil (from catalyzer), polyethylene fine powder, micro-aluminum alkyl to accumulate in knock out drum, easily cause magnetic flap level gauge to stop up, cause liquid level indication distortion, judgement is patrolled and examined at the scene of impact, even if find there is hydrops in knock out drum, also needs to be led and drenched outer row by knock out drum bottom, be mixed with liquid exposure very easily spontaneous combustion in air of hexane and a small amount of aluminum alkyl, have great potential safety hazard;
2, magnetic float liquidlevel meter DCS liquid level deixis is damaged at present, and knock out drum liquid level trend cannot be monitored in control room, even if more renew level meter, still will regularly discharge knock out drum hydrops, and the potential safety hazard of discharge process cannot be eliminated;
While 3, being provided with skirt support due to knock out drum bottom, electrical tracing line can only be entangled in buffering tank body middle part, cannot effectively heat tank base hydrops, and during winter operation, knock out drum bottom still has hydrops to produce;
Above 3 kinds of methods reclaim suction port of compressor knock out drum hydrops problem in the time of still can not effectively solving winter operation, when also causing reclaiming compressor and moving in the winter time, because inlet buffer hydrops causes compressor interlocking situation, happen occasionally.
Model utility content
The purpose of this utility model is to provide a kind of suction port of compressor knock out drum, and this knock out drum can thoroughly solve the problem of knock out drum bottom, suction port of compressor hydrops, guarantees to reclaim compressor stable operation in winter.
Concrete technological scheme of the present utility model is as follows:
A suction port of compressor knock out drum, comprises knock out drum tank body, also comprises skirt, described skirt is connected with knock out drum tank base, skirt is provided with at least two hand holes, is provided with companion's hot coil in skirt, and the entry end of companion's hot coil is connected with two hand holes wherein respectively by link with outlet end.
Described companion's hot coil is metallic hose, and metallic hose is concentric circle and is distributed in skirt; Make the steam liberated heat distribution in metallic hose more even, be more conducive to prevent the hydrops of knock out drum bottom.
The outlet end of above-mentioned metallic hose is connected with STEAM TRAP; Described STEAM TRAP is used for the water of condensation in metallic hose to discharge.
The entry end of described metallic hose is provided with valve, for controlling the amount of the steam that enters metallic hose and metallic hose, is convenient for changing when damaged.
Described link is flange.
The utility model arranges skirt in the bottom of knock out drum tank body, is provided with companion's hot coil in skirt, and knock out drum skirt is increased to insulation, can effectively solve the problem that reclaims knock out drum bottom, suction port of compressor hydrops.During winter operation, repeatedly temperature monitoring is carried out in knock out drum bottom, all, more than 30 degree, the recovery compressor interlocking that knock out drum hydrops causes does not occur in whole winter operation, facts have proved that scheme implementation described in the utility model is respond well.The utility model is simple in structure, safe, easy to operate.
