Description
Technical field
The present invention relates to a kind of filler and purification coal gas method thereof that purifies coal gas, specifically, is that a kind of fibrous nodules filler is used for the purifying method to coal gas, is applicable to the gas purification that gasification of coal, coking, low-temperature pyrolysis produce.
Background technology
Publication number is a kind of " the Raschig ring filler " of CN 201710985 U, comprise ring body and circular hole, the wall of ring body is provided with 2～5 circular holes, its characteristics have been to improve porosity that this filler has and the circulating capacity of fluid, but this Raschig ring exists specific surface area less, the deficiency of degradation aspect under the mechanical property, and this filler is not suitable for washing the filler absorption of coal tar in the coal gas.
Publication number is a kind of " screen waviness packings " for CN 1751782A discloses, and comprises the silk netting that is laminated into crack structure by two-layer or two-layer above silk screen, and silk netting is pressed into the ripple sheet, is stacked by the multi-layer silk screen sheet to constitute screen waviness packings.Its advantage has been to improve the wettability of screen waviness packings, has increased effective mass transfer area, but owing to there is not versatility, needs customization, and installation exists inconvenient, and does not overcome the susceptible to plugging shortcoming of heap material of loosing fully.
Publication number is that CN 102492490A discloses " a kind of gas purification process "; its method is after the raw gas that contains tar is sent into high temperature cyclone separator and removed the macrobead dust; raw gas is again through the further dedusting of high-temperature filter; coal gas after the dedusting advances the coal tar fluid counter current contact washing of quenching column and 40-80 ℃ through waste heat boiler heat exchange to 350-300 ℃ coal gas; the coal tar that contains in the coal gas enters in the coal tar fluid, and cat head washing is cooled to 40～100 ℃ of clean gas cabinet of supplying gas.This technology is by washing with coal tar fluid counter current contact, being unsuitable for the purification to the high raw gas of coal tar content to the coal tar pick up the oil.
Also having publication number is that CN 102010760 A disclose " a kind of gas washing udst separation technology ", this processing step is as follows: dust-laden coal gas is fed the dedusting washing tower wash with the water coolant counter current contact on its top, again with the counter current contact scrubbing dust collection of purifying waste water of cat head; Waste water after the dedusting imports the water of settling tank post precipitation and squeezes into the water cooling tower cooling by hot water pump at the bottom of the washing Tata, the moisture that enters water cooling pond again becomes two-way to use; Coal gas after washing enters the recirculated water counter current contact on purification and washing tower and its top and washs, again with the further washing, purifying of de-mineralized water counter current contact of cat head; Water after the purification and washing is divided into two tunnel, one tunnel water after separating after importing circulation groove at the bottom of the tower squeezes into purification and washing tower top through recycle pump again and recycles, and another road has the less water of turbidity to discharge circulation groove to handle outward.This technology good dedusting effect, but be unsuitable for washing, purifying to coal tar in the raw gas.
Above-mentioned packing tower adsorption stuffing and raw gas washing, purifying technology, the problem of its existence is that throughput is limited, and turndown ratio is poor, and the coal tar separation efficiency is not high, and equipment is huge and do not meet the energy-conserving and environment-protective requirement.Absorb incomplete tar in the coal gas and also influence the work-ing life of follow-up equipment and follow-up quality product.
Absorbent cotton be by raw cotton through removing inclusion, degreasing, bleaching, washing, drying, arrangement are processed into.Absorbent cotton has good water-absorbent, and fiber softening is elongated, and pure white high resilience does not contain detrimental impurity such as acid, alkali, than the easier absorption liquid of common cotton; Man-made fiber is that to use natural polymer or synthetic polymer through chemistry or physical method modification be the fiber that raw material is made, and its kind is very many, for example trevira, glass fibre cotton etc.The present invention relates to fibrous nodules in a kind of fibrous nodules filler and be applicable to the man-made fiber processing and fabricating that absorbs coal tar by absorbent cotton, glass fibre cotton or other, can effectively solve the deficiency that above-mentioned filler exists in gas purification is used, significantly improve throughput.
Summary of the invention
Based on the method for above-mentioned existing filler and purification coal gas thereof, the objective of the invention is to further improve purify coal gas efficient, reduce cost, the method for a kind of fibrous nodules filler and purification coal gas thereof is provided.
To achieve these goals, the measure that the present invention takes is a kind of fibrous nodules filler and the method that purifies coal gas thereof, and wherein a kind of fibrous nodules filler comprises spherical shell and fiber pelletizing; It is characterized in that: described spherical shell is to be constituted by fastener I and fastener II by two Stainless Steel Cloth hemispherical Shell I and Stainless Steel Cloth hemispherical Shell II; Described fiber pelletizing is and the corresponding absorbent cotton of spherical shell or glass fibre cotton that its density is 15～30 mg/cm
3, diameter is 20～80 mm.
A kind of aforesaid fibrous nodules filler is used for purifying the method for coal gas, its described method be with coal gas by the waste heat boiler heat exchange after temperature drop to 250～300 ℃, again after water cooler is cooled to 30～80 ℃, bottom air inlet by the absorption tower enters, successively through carrying out absorption cleaning in bottom, absorption tower tower body, middle part tower body and the top tower body that the fibrous nodules filler is housed, purify the back and send into gas storage holder by air outlet, top, absorption tower, after the fibrous nodules packing layer reaches capacity, the fibrous nodules filler is carried out dissection process; Wherein, the fibrous nodules filler diameter in the tower body of described bottom is 55～65 mm, and density is 15～20 mg/cm
3Fibrous nodules filler diameter in the tower body of described middle part is 40～50 mm, and density is 20～25 mg/cm
3Fibrous nodules filler diameter in the tower body of described top is 25～35 mm, and density is 25～30 mg/cm
3The volume ratio of the bottom tower body on described absorption tower, middle part tower body and top tower body is 1:1.5:1.5; The fibrous nodules filler loadings on described absorption tower accounts for 70%～80% of the interior space of tower.
