Description
Prezenta invenție se referă la brichete din negru de fum, obținute în scopul valorificării energetice a acestor două produse secundare, negru de fum și celolignină, combustibile, re- 5 zultate din procesele industriale ale Combinatului Chimic Craiova.BACKGROUND OF THE INVENTION The present invention relates to briquettes made of carbon black, obtained for the purpose of energy recovery of these two by-products, carbon black and cellolignin, fuels, resulting from the industrial processes of the Craiova Chemical Combined.
Sînt cunoscute brichete combustibile de diferite tipuri, pe bază de praf de cărbune cu adaosuri de materiale corn- 10 bustibile celulozice, var pulverulent și lianți uzuali, care prezintă unele dezavantaje legate de necesitatea folosirii materialelor cărbunoase cu preț de cost ridicat, iar produsele care se obțin în 15 cazul folosirii unui matrerial cărbunos inferior au putere calorică redusă. De asemenea, se cunosc brichete pe bază de negru de fum, celolignină, var stins și poliacetat de vinii, care prezintă 20 unele dezavantaje legate de rezistența la sfărîmare.Fuel briquettes of different types are known, based on coal dust with additions of corn material- 10 cellulose bushes, powdered lime and common binders, which have some disadvantages related to the need to use high-cost carbon materials, and the products that are obtain in the case of the use of a lower carbonaceous material have reduced calorific power. Also, briquettes based on black smoke, cellolignin, extinguished lime and vinyl polyacetate are known, which has 20 disadvantages related to crushing resistance.
Scopul invenției de față este de obținere a unor produse cu putere calorică și rezistență la sfărîmare supe- 25 rioare, fără necesitatea introducerii în compoziție a materialului cărbunos superior.The object of the present invention is to obtain products with higher calorific value and breaking resistance, without the need to introduce the upper carbon material into the composition.
Problema pe care o rezolvă invenția de față este de stabilire a unei compo- 30 ziții optimizate a amestecului din care se realizează brichetele avînd la bază negru de fum ca material carbonic.The problem solved by the present invention is to establish an optimized composition of the mixture from which the briquettes having a black smoke base as a carbon material are made.
Brichetele conform invenției înlătură dezavantajele menționate mai 35 sus, prin aceea că, la o tonă de produs întărit conțin, 50 kg negru de fum, 880 kg celolignină, 50 kg var stins praf, 5 kg amidon, cît și 15 kg poliacetat de vinii, sub formă de peliculă exterioară 40 protectoare.The briquettes according to the invention remove the disadvantages mentioned above, in that, in one tonne of cured product, they contain 50 kg of black smoke, 880 kg of cellolignin, 50 kg of powdered lime, 5 kg of starch and 15 kg of polyacetate of vinyl, in the form of outer film 40 protectors.
Se dă mai jos un exemplu de realizare a invenției.The following is an example of an embodiment of the invention.
Pentru obținerea brichetelor conform invenției se folosesc următoarele 45 materii prime:The following 45 raw materials are used to obtain the briquettes according to the invention:
- pastă de negru de fum, produs secundar de la obținerea industrială a acetilenei din gaz metan. Pasta conține 10% negru de fum Și 90% apă; 50- black smoke paste, a by-product from the industrial production of acetylene from methane gas. The paste contains 10% black smoke and 90% water; 50
- celolignină, produs secundar, de la obținerea industrială a furfurolului din cocenii de porumb, tratați cu H2SO4. Cantitatea reziduală de H2SO4 din celolignină a fost neutralizată cu var stins în praf, Ca(OH)2.- cellolignin, a by-product, from the industrial production of furfurol from corn cobs, treated with H2SO4. The residual amount of H2SO4 in cellolignin was neutralized with powdered lime, Ca (OH) 2.
Determinările experimentale au demonstrat că neutralizarea necesită 5% var;Experimental determinations have shown that neutralization requires 5% lime;
- amidonul comercial reprezintă liantul;- commercial starch represents the binder;
- var stins în praf, comercial; poliacetat de vinii comercial (aracet) folosit pentru a mări rezistența la sfărîmare prin pelicula de polimer formată.- powder-dried lime, commercial; commercial vinyl polyacetate (strap) used to increase the breaking resistance through the formed polymer film.
Se omogenizează într-un amestecător 500 kg pastă de negru de fum cu 5 kg amidon. După omogenizare, amestecul se încălzește la 80°C pentru dizolvarea amidonului, după care se întrerupe încălzirea. Se adaugă celolignina și 50 kg var stins praf. După omogenizare, pasta obținută este utilizată pentru brichetare prin presare, în tipare cu 70 daN/cm.Stir in 500 kg of black smoke paste with 5 kg of starch in a blender. After mixing, the mixture is heated to 80 ° C to dissolve the starch, after which the heating is stopped. Add celolignin and 50 kg lime powder. After homogenization, the obtained paste is used for briquetting by pressing, in patterns with 70 daN / cm.
Se recomandă forma cilindrică.The cylindrical shape is recommended.
După decofrare , brichetele se imersează într-o soluție de poliacetat de vinii comercial (aracet): apă în proporție de 1,3, în volume.After clearing, the briquettes are immersed in a solution of commercial polyacetate vinegar (aracet): water in the amount of 1.3, in volumes.
Apoi, brichetele se introduc într-un uscător, unde se va realiza ridicarea treptată a temperaturii și menținerea ei constantă la 135 °C, timp de o oră.Then, the lighters are placed in a dryer, where the temperature will be raised gradually and kept constant at 135 ° C for one hour.
Brichetele întărite au următoarele caracteristici: indicele de sfărîmare 100%, rezistență la compresiune 28 daN/cm, puterea calorică de 4450kcal/, densitatea aparentă700 kg/m, temperatura de început de ardere 730°C, sfîrșit de ardere 730°C, reziduuri 9%.The hardened briquettes have the following characteristics: 100% crushing index, compressive strength 28 daN / cm, calorific value of 4450kcal /, apparent density700 kg / m, starting temperature of combustion 730 ° C, end of burning 730 ° C, residues 9 %.
Invenția de față prezintă următoarele avantaje:The present invention has the following advantages:
- se valorifică energetic două produse secundare, combustibile, nevalorificate pînă în prezent;- two by-products, fuels, not used up to date are used energetically;
- puterea calorică a brichetelor este de 4450 kcal/kg;- the calorific power of the lighters is 4450 kcal / kg;
- energia electrică și termică necesară este scăzută, și anume, pentru o tonă de brichete sînt necesare 16 kwh energie electrică și 0,25 Gcal energie termică.- the necessary electrical and thermal energy is low, ie, for one ton of lighters, 16 kwh of electricity and 0.25 Gcal of thermal energy are needed.
