Abstract
An apparatus for the mechanical separation of oil and tar from gas condensate, which comprises a tank which is equipped with a container to be traversed by gas condensate, which contains metallurgical coke, and with parallel plate separators, wherein partitions divide the container volume into compartments in which the oil and the tar settle from the gas condensate under the influence of gravity.
Description
Technical field
The present invention relates to a kind of for the equipment from gas condensate mechanical type separating oil and pitch, this equipment comprises tank, this tank is equipped with the container will crossed by gas condensate, this container comprises coalescent auxiliary equipment, and this tank is equipped with parallel plate separators, wherein, vessel volume is separated into multiple room by separator, and in the plurality of room, oil (oil) and pitch (tar) precipitate from gas condensate under the influence of gravity.
Background technology
By means of fixed bed pressure gasification reactor, at high temperature and in majority of case under superpressure, using steam and oxygen as gasifying medium, by solid fuel such as coal, coke or other carbonaceous fuel gasifyings, to obtain forming gas, this forming gas comprises carbon monoxide and hydrogen, wherein, obtain solid-state ash, this solid-state ash is discharged by from reactor via ash discharge stove, and this ash discharge stove is formed rotary furnace in many cases.The reactor of the type is often also referred to as FBDB (=fixed bed dry bottom) pressure gasifier.In the cooling period of output gas, form gas condensate.Here it is the condensed steam content coming from the water content of raw material (when coal) of this gas, undecomposed steam and form water, this formation water is obtained by the partial oxidation of hydrogen between pneumatolytic stage, this hydrogen comprises in the feed, with reference to the 4th edition Ullmanns
der technischen Chemie, the 14th volume, the 449th page.
Can using gas condensate as before wastewater treatment in biological purification plant, for the reason of the recovery of environmental protection and enabled production, gas condensate must by reprocessing.First, oil, pitch and dust and phenol subsequently and ammonia are separated by from gas condensate.Therefore, in the incipient stage of these treatment steps, oil and pitch are mechanically separated by from gas condensate.
For being settling tank with pitch from the equipment that gas condensate mechanical type is separated by oil, in this settling tank, only due to the impact of its density variation and gravity, impurity is separated from gas condensate.The equipment of the type itself is known, with reference to the 4th edition Ullmanns
dertechnischen Chemie, the 14th volume, the 450th page, Figure 59.Therefore more coarse pitch particle and oil droplet can be separated from gas condensate by with rational measure.But; above-mentioned settling tank is not be very suitable for being separated less pitch particle and oil droplet, and this is due to separation process and then carries out slowly and need gas condensate to be detained for a long time in these settling tanks and thus need the very large volume of these equipment and a large amount of spaces and cost.
Therefore, the object of this invention is to provide a kind of equipment, use this equipment mechanically and also meticulousr pitch and elaioleucite can be separated from gas condensate with the space of fair amount and cost.
Summary of the invention
This object is solved by equipment according to claim 1.
In order to be separated, the present invention also utilizes the density variation between impurity, oil (oil) and pitch (tar) and water condensate.
In order to accelerate to be emulsified in, that oil droplet in gas condensate and pitch drips is coalescent, makes gas condensate first through smelter coke filler, and subsequently through parallel plate separators.The plate of these separators also can be formed corrugated plating, and these separators are called as corrugated plating separator in this case.
Equipment according to the present invention is made up of the outer tank with rectangular cross section.Tank can be opened towards air or close.When carrying out composition that degasification obtains to gas condensate and discharged in the mode of environmental compatible, under the slight excess of 30 to 60mbar, design tank with closing form, the slight excess of this 30 to 60mbar is formed by stacking by the air-flow be such as made up of nitrogen.Air-flow is discharged from tank is entered into cleaning device or for such as burning by means of blowpipe.
Outer tank is divided into multiple room by separator, and gas condensate crosses the plurality of room one by one.Inlet is arranged in the middle part of tank with being centered, and comprises the filler with smelter coke.Filler is accommodated in rectangular vessel, and the upper side and lower side of this rectangular vessel is perforation, and filler can be crossed by gas condensate.Below filler, via supplying duct, gas condensate to be cleaned is supplied in equipment.The bottom of room has conical design and has opening at deepest point place, and this opening is used for the pitch sunk in bottom to discharge.Second Room and so-called oil separation chamber are positioned at the top of inlet, and gas condensate enters into this oil separation chamber after crossing smelter coke.
In this oil separation chamber, gas condensate logistics is shunted, make each the equal overflow of part stream be entered into corresponding further last tank room by parallel plate separators or corrugated plating separator, this parallel plate separators or corrugated plating separator are arranged to left and the right of inlet.The oil droplet formed in coke packing and in parallel plate separators or corrugated plating separator rises at this and is formed in the oil reservoir on surface in gas condensate.Via downflow weir, the oil from this oil reservoir is taken out from tank.
The pitch be included in gas condensate drips similarly coalescent in parallel plate separators or corrugated plating separator, and sinks in the conical lower section of the room of the next-door neighbour of so-called condensate downstream chamber, and separator leads to the conical lower section of the room of this next-door neighbour.Then, pitch can be taken out by from this conical lower section.
Separator between oil separation chamber and condensate downstream chamber is equipped with passage, this condensate downstream chamber immediately arrives right and left, and this passage for flowing out from parallel plate separators or corrugated plating separator and the part oil risen at separator on the flow direction of gas condensate.
Of the present invention favourable in, conduit is connected to passage, this conduit in oil separation chamber below liquid level preferred 0.2m place slightly open.By means of these conduits, avoid oil droplet and again partly taken away by gas condensate logistics and can not surface be risen to.
Clean gas condensate is extracted from condensate downstream chamber respectively via a downflow weir.The height of the height of the downflow weir of oil separation chamber and the downflow weir of condensate downstream chamber must regulate each other, makes the downflow weir via oil separation chamber extract most anhydrous oil phase.
The invention further relates to the purposes according to equipment of the present invention, for being mechanically separated from gas condensate with pitch by oil, this gas condensate obtains during the fixed bed pressure gasification of carbon-containing fuel, obtains particularly advantageous stalling characteristic thus.
