Description
본 발명은 정수슬러지를 이용한 층간소음방지판재 제조방법에 관한 것으로서, 보다 상세하게는 정수장의 정수과정에서 배출되는 정수슬러지에, 제지공장에서 배출되는 제지(펄프)슬러지와 바인더(접착제)로 시멘트 및 액상으로 현탁된 무기질 세라믹과 첨가제로 생석회 또는 폐석고미분말 탈취제 등을 혼합기에서 반응시켜서 혼합한 후, 상기의 혼합물을 성형기에서 압착성형한 다음, 상온에서 건조시켜 판재 형상으로 가공하여 제조한 제품으로서 판재의 균열현상을 방지함은 물론, 경량성, 흡음성, 단열성, 내화성이 우수한 정수슬러지를 이용한 층간소음방지판재 제조방법에 관한 것이다.The present invention relates to a method for manufacturing an interlayer noise preventing plate material using purified sludge, and more specifically, to purified water sludge discharged from a water purification process of a water purification plant, cement and a paper (pulp) sludge and binder (adhesive) discharged from a paper mill. After reacting and mixing the mineral ceramic suspended in liquid phase with additives such as quicklime or waste-rock fine powder deodorant in a mixer, the mixture is press-molded in a molding machine, dried at room temperature and processed into a plate shape. The present invention relates to a method of manufacturing an interlayer noise preventing plate using water purification sludge having excellent light weight, sound absorption, heat insulation, and fire resistance as well as preventing cracking.
일반적으로 정수장의 정수과정에서 배출되는 정수슬러지는 원수중에 현탁되어 있거나 부유하는 이물질들이 모여서된 유동성의 반고체성 물질로서 그 입자가 많은 수분을 함유하면서 미세하고 가벼우며 점성이 부족한 특성으로 인하여 기계적으로 탈수시켜서 고형화 하기에는 추가적인 공정과 많은 에너지가 필요하는 등 정수슬러지의 처리비가 상승하여 재활용에 제한이 되고 있다. Generally, the purified sludge discharged from the water purification process of water purification plant is a fluid semi-solid substance that is suspended or suspended in the raw water and mechanically dehydrated due to its fine, light and poor viscosity. In order to solidify the wastewater, additional treatment and a large amount of energy are required, and the treatment cost of the purified water sludge is increased, thereby limiting recycling.
따라서, 정수슬러지의 단순처리단계를 넘어서 적극적으로 활용하는 방법을 모색하는 것이 바람직함에 따라 환경적으로나 경제적으로 최대한의 효과를 거둘 수 있는 정수슬러지를 재활용할 수 있는 한 방법으로서, 본 발명인 정수슬러지를 이용한 층간소음방지판재 제조방법을 안출하기에 이르렀다. Therefore, as it is desirable to seek a method of actively utilizing the water treatment sludge beyond the simple treatment step, as a method for recycling the purified water sludge which can achieve the maximum effect environmentally and economically, The method of manufacturing the interlayer noise preventing plate used has been devised.
예를 들면, 대한민국등록특허공보 등록번호 제10-1301128호에는 함수율이 높은 정수슬러지를 소성로에서 발생되는 폐열을 회수시켜 건조로에 유입시켜 활용함으로써, 에너지 절약을 도모하면서 환경오염의 배출을 최소화 하고자 정수슬러지의 활성화 방법이 기술 되어 있으며, For example, Korean Patent Publication No. 10-1301128 discloses water purification sludge with high moisture content to recover waste heat generated from a kiln and flow it into a drying furnace, thereby minimizing the emission of environmental pollution while conserving energy. The method of activation of the sludge is described,

동 공보 등록번호 제10-0860017호에는 슬러지와 조분의 포졸란 물질(Reject Ash, 잔사회),플라이애쉬, 폴리에스테르, 인조대리석 및 기타 화학제품 제조공정에서 부산물로 발생되는 공정오니, 황산제일 및 산화칼슘, 고로슬래그 미분말, 포틀랜드 시멘트 및 이들의 혼합물로 이루어진 군에서 선택된 1종의 무기 바인더를 포함하는 공정오니 및 슬러지를 이용한 건축자재용 흙골재 조성물 및 이의 제조방법에 대한 기술이 공개되어 있다. Publication No. 10-0860017 discloses sludge and crude process sludges, crude ash and oxidation, which are produced as by-products from the production of pozzolanic materials (reject ash), fly ash, polyesters, artificial marble and other chemicals. Disclosed is a technique for a soil aggregate composition for building materials using a process sludge and sludge including one inorganic binder selected from the group consisting of calcium, blast furnace slag fine powder, portland cement, and mixtures thereof.
그런데, 종전의 기술들은 정수슬러지에 포함되어 있는 수분을 제거하기 위하여 가열하여 소성하거나 화학물질을 사용함에따라 에너지의 사용과 대기오염물질들이 발생하여 제2의 환경오염이 발생할 우려가 있을 뿐만 아니라 제조된 제품들도 기존 건축자재와의 차별성이 부족한 것이다.By the way, the conventional techniques are not only a second environmental pollution due to the use of energy and air pollutants generated by heating or baking to remove the water contained in the purified sludge or by using chemicals, Even those products that are not enough to differentiate from existing building materials.

본 발명은 여러가지 다양한 형태로 구현하는 것이 가능하며, 이하에서 설명하는 실시예들에 한정되지 않는다.The present invention can be embodied in various forms and is not limited to the embodiments described below.
이하에서는 본 발명을 명확하게 설명하기 위해서 본 발명과 밀접한 관계가 없는 부분은 상세한 설명을 생략하였으며, 명세서 전체를 통하여 동일 또는 유사한 구성요소에 대해서는 동일한 참조 부호를 붙이고, 반복적인 설명을 생략한다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the accompanying drawings, wherein like numerals refer to like elements throughout.
먼저, 본 발명의 일실시예에 따른 정수슬러지를 이용한 층간소음방지판재 제조방법은, 도 1에 나타낸 바와 같이, 케이크 상태의 정수슬러지를 분쇄기에서 분쇄하는 단계가 진행된다. 이는 수분이 존재하는 정수슬러지를 1 ~ 3mm로 분쇄하는 공정이다.First, in the method for manufacturing an interlayer noise preventing plate material using purified sludge according to an embodiment of the present invention, as shown in FIG. 1, the step of grinding the purified sludge in a cake state is performed in a grinder. This is a process of grinding the purified water sludge to 1 ~ 3mm.
종래의 기술들은 정수슬러지의 수분을 제거하기위하여 가열 또는 소성시키는 탈수공정을 거친 후 바인더와 혼합하여 고화시켜 성형하고 있으나, 본 발명은 정수장에서 배출된 정수슬러지를 그대로 분쇄기에 투입하고서 수분이 존재하는 정수슬러지를 1 ~ 3mm의 미세입자로 분쇄하는 공정(S10)으로 이루어지고, 정수슬러지의 사용량은 35∼45중량%가 바람직하며, 사용량이 35중량% 미만일 경우에는 제조되는 판재의 내화성이 저하되는 단점이 있고, 반면에 45중량%를 초과하는 경우에는 제조되는 판재의 강도가 저하되고 흡음성이 저하되는 문제점이 발생한다.Conventional techniques are formed by mixing with a binder and then solidifying by heating or baking to remove water from purified water sludge, but the present invention is to put the purified water sludge discharged from the water purification plant as it is in the grinder as it is present It is made of a step (S10) of grinding the purified sludge into fine particles of 1 to 3mm, the use amount of the purified sludge is preferably 35 to 45% by weight, if the amount is less than 35% by weight, the fire resistance of the produced plate material is lowered On the other hand, if it exceeds 45% by weight, the strength of the plate produced is lowered and the sound absorbing problem occurs.
또한, 제지(펄프)슬러지를 분쇄기에서 3 ~ 5mm의 입자로 분쇄하는 공정(S20)단계가 진행된다. 이때 제지(펄프)슬러지를 분쇄하는 공정(S20)에서는 수분이 함유된 상태로 사용할 수 있으며, 향후의 성형과 건조 공정의 용이성 측면에서 제지(펄프)슬러지의 사용량은 30∼40중량%가 바람직하며, 사용량이 30중량% 미만일 경우에는 제조되는 판재의 경량화가 미약한 단점이 있고, 반면에 40중량%를 초과하는 경우에는 제조되는 판재의 강도가 저하되고 내열성 및 내화성이 저하되는 문제점이 있다.In addition, the process (S20) step of grinding the paper (pulp) sludge into particles of 3 ~ 5mm in the mill. At this time, in the process of crushing the paper (pulp) sludge (S20) can be used in the state containing water, the use of paper (pulp) sludge in terms of ease of the future molding and drying process is preferably 30 to 40% by weight. If the amount is less than 30% by weight, the weight of the plate produced is weak. On the other hand, if it exceeds 40% by weight, the strength of the plate produced is lowered, and heat resistance and fire resistance are deteriorated.
그리고, 제지(펄프)슬러지는 자체적으로 접착제로서의 능력을 가지고 있으므로 접착제의 사용량을 줄일 수 있어서, 판재의 주재료뿐 아니라, 부재료로써의 작용도 함께하게 된다.In addition, since the paper (pulp) sludge has its own capacity as an adhesive, the amount of adhesive used can be reduced, so that not only the main material of the sheet material but also a function as a subsidiary material are combined.
또한, 본 발명의 정수슬러지를 이용한 층간소음방지판재를 제조하기 위하여 주원료인 정수슬러지와 제지(펄프)슬러지를 혼합하는 공정(S30)을 거쳐 상기의 양 슬러지를 견고하게 접착시키고, 슬러지를 가열하여 탈수시키지 않고도 용이하게 판재형상으로 성형하고 가공할 수 있게하기 위하여, 바인더(접착제)로 시멘트 20 ~ 25 중량%와 액상으로 현탁된 무기질 세라믹 4 ~ 5 중량%를 사용하는 공정(S40)을 실시함으로써 제조되는 판재의 균열현상을 방지함은 물론, 강도와 경량성 및 흡음성과 단열성을 동시에 유지할 수 있다.In addition, in order to manufacture the interlayer noise preventing plate material using the purified water sludge of the present invention, through the step (S30) of mixing the purified water sludge and the paper (pulp) sludge which is the main raw material, both the sludges are firmly adhered, and the sludge is heated. In order to be easily formed and processed into a plate shape without dehydration, by performing a step (S40) using 20 to 25% by weight of cement and 4 to 5% by weight of inorganic ceramic suspended in a liquid phase as a binder (adhesive) In addition to preventing cracking of the manufactured plate material, it is possible to maintain strength, light weight, sound absorption and heat insulation at the same time.
그리고, 첨가제로 생석회 또는 폐석고미분말 1 ~ 2 중량%을 상기의 정수슬러지와 제지(펄프)슬러지 혼합물에 투입하여 실시하는 작업공정(S40)중 발생하는 악취 및 슬러지에 포함되어 있는 중금속 등을 흡취 및 흡착하게 할 뿐만 아니라, 상기의 바인더(접착제)인 시멘트와 액상으로 현탁된 무기질 세라믹과 함께 슬러지에 함유되어 있는 물과 결합하는 수화반응을 통해 수화열을 발생하게 되는데, 이는 함수율이 높은 정수슬러지와 제지(펄프)슬러지에 함유된 수분과 결합하면서 발열반응인 수화반응을 일으키게 되므로 슬러지에 포함된 수분을 증발시켜 슬러지가 용이하게 고형화될 수 있는 것이다. In addition, by adsorbing 1 to 2% by weight of quicklime or waste-rock fine powder as an additive to the above-mentioned purified water sludge and paper (pulp) sludge mixture, the odor generated during the work process (S40) and heavy metals contained in the sludge are absorbed and In addition to adsorbing, the heat of hydration is generated through a hydration reaction in which the binder (adhesive) cement and the inorganic ceramic suspended in the liquid phase are combined with water contained in the sludge. When combined with the water contained in the (pulp) sludge causes a hydration reaction, which is an exothermic reaction, the sludge can be easily solidified by evaporating the water contained in the sludge.
또한, 수화반응을 통해 고형화가 진행되는 상기의 슬러지를 성형기에 투입하여 판재형상으로 성형시키는 작업공정(S50)을 진행하게 되는데, 이때에는 고형화가 진행되는 슬러지가 투입된 성형기를 압착시켜서 판재형상으로 압출시키고 완전히 건조시킨 후, 상기의 건조된 압출물을 절단하여 임의의 규격으로 제작하여 출품하면, 본 발명인 정수슬러지를 이용한 층간소음방지판재가 완성되는 것이다. In addition, through the hydration reaction, the sludge into which the solidification proceeds to the molding machine is carried out to perform a work step (S50) for molding into a sheet shape, in which case the press is pressed into the sheet shape by pressing the molding machine into which the sludge is solidified. After drying, and completely dried, the dried extrudate is cut and manufactured in any standard, and the interlayer noise prevention plate material using the purified water sludge of the present invention is completed.
그리고, 상기의 고형화가 진행되는 슬러지를 성형기에 압착시켜서 판재형상으로 압출시키는 작업공정(S50)을 거친 후, 완전히 건조된 압출물인 판재의 표면에 필요에 따라서 열경화성수지를 도포하고 재건조시키는 작업공정(S60)을 거쳐서 정수슬러지를 이용한 층간소음방지판재를 생산할 수도 있으며, 이때에는 작업공정의 추가로 인하여 다소 생산비용의 상승은 있으나, 상기의 열경화성수지를 도포하고 재건조시키는 작업공정(S60)을 거친 정수슬러지를 이용한 층간소음방지판재는 판재의 강도와 내화성 및 단열성이 보다 우수한 판재로 생산되는 것이다. Then, after the working process (S50) of compressing the sludge in which the solidification proceeds to the molding machine to extrude into a plate shape, the work process of applying and redrying the thermosetting resin on the surface of the plate material, which is a completely dried extrudates as necessary It is also possible to produce the interlayer noise preventing plate using the purified water sludge through (S60), in which case there is a rise in the production cost due to the addition of the work process, the work process (S60) to apply and re-dry the thermosetting resin The interlayer noise preventing plate using coarse purified water sludge is produced with a plate having better strength, fire resistance and insulation.
상기에서는 본 발명에 따른 정수슬러지를 이용한 층간소음방지판재 제조방법의 바람직한 실시예에 대하여 설명하였지만, 본 발명은 이에 한정되는 것이 아니고, 특허청구범위와 명세서 및 첨부한 도면의 범위 안에서 여러가지로 변형하여 실시하는 것이 가능하고, 이 또한 본 발명의 범위에 속한다.
In the above, a preferred embodiment of the method for manufacturing an interlayer noise preventing plate material using purified sludge according to the present invention has been described. However, the present invention is not limited thereto, and various modifications are made within the scope of the claims and the specification and the accompanying drawings. It is possible to do this and this also belongs to the scope of the present invention.
[실시예][Example]
다음의 실시예는 본 발명을 좀 더 상세히 설명하는 것이지만, 본 발명의 범주를 한정하는 것은 아니다.
The following examples illustrate the invention in more detail but do not limit the scope of the invention.
[실시예 1]Example 1
정수장에서 배출된 정수슬러지를 분쇄기에 투입하여 1 ~ 3mm의 입자로 분쇄한 정수슬러지 37중량%와, 분쇄기에서 분쇄되어 3 ~ 5mm의 입자로 해리되어 있는 제지슬러지 33중량%를 혼합기에 투입하고서, 여기에 바인더로 시멘트 23중량% 및 액상으로 현탁된 무기질 세라믹 5중량%와 첨가제로 생석회 2중량%을 상기의 양 슬러지 혼합물에 투입하고서, 2시간동안 혼합기를 가동하여 완전혼합시켜, 수화반응이 완결된 후에 반고형화된 상기의 슬러지를 성형기에 투입하고서 상온에서 70Kg/cm2 의 압력으로 3Cm 두께의 판재을 압착성형한 후, 이를 건조기로 이송하여 상온에서 자연 건조시켜 경량판재를 제조하였다.The purified sludge discharged from the water purification plant was put into the grinder, and 37 wt% of the purified sludge ground into particles of 1 to 3 mm, and 33 wt% of the paper sludge ground from the mill to dissociated into 3 to 5 mm particles were added to the mixer. 23% by weight of cement as a binder and 5% by weight of inorganic ceramic suspended in liquid form and 2% by weight of quicklime as additives were added to the above sludge mixture, and the mixer was operated for 2 hours to complete mixing, thereby completing the hydration reaction. After the semi-solidified sludge was added to the molding machine, the plate was press-molded to a thickness of 3 cm with a pressure of 70 kg / cm 2 at room temperature, and then transferred to a dryer to naturally dry at room temperature to prepare a lightweight plate.
그리고, 제조된 경량판재의 강도를 측정한 결과, 공지의 경량판재와 비교시 동등 이상의 강도를 가지고 있음을 알 수 있었으며, 수분이 함유된 슬러지를 그대로 사용하므로서 공정이 보다더 용이할 뿐만 아니라 비용면에서도 경제적이었다. In addition, as a result of measuring the strength of the manufactured lightweight plate material, it can be seen that it has a strength equal to or higher than that of a known lightweight plate material, and the process is easier and more costly by using the sludge containing water as it is. It was economical too.
또한, 제지슬러지를 사용함에따라 판재의 균열현상을 방지함은 물론, 경량성, 흡음성, 단열성이 보다 우수한 층간소음방지판재를 제조할 수 있었다.
In addition, the use of paper sludge prevented the occurrence of cracks in the sheet material, as well as producing an interlayer noise preventing plate material having better light weight, sound absorption, and heat insulation.
