Abstract

The invention discloses a method for synthetizing solid fuel by mixing house refuse with fire coal, which comprises the following steps of: separating metal from recycled house refuse and then crushing; then stirring the crushed house refuse together with crushed fire coal and yellow clay powder; profiling in a rolling type molding press after evenly stirring; when 5 to 6cm of ball-shaped material is profiled, entering a dryer for drying; when the drying effect is completely reached, placing the dried ball-shaped material in a crocodile breaker and then breaking into 1 to 2cm of grain bulk material, thereby producing the solid fuel. The method has the advantage that the house refuse treatment is more perfect, and the prepared solid fuel has easy storage, no secondary pollution and simple preparation process, and the house refuse can be effectively utilized, thereby saving energy resources.

Description

Utilize the method for mixing house refuse with fire coal synthetizing solid fuel

Technical field:

The present invention relates to a kind of method of garbage treatment, specifically a kind of method and this solid-fuelled second stage employ of utilizing the mixing house refuse with fire coal synthetizing solid fuel.

Background technology:

The generating of the direct burning of tradition gained heat is more common mode in the known technology of refuse treatment, but waste plastic directly burns in the domestic refuse, consequently will inevitably produce a large amount of obnoxious flavoures such as Dioxins, seriously causes topsoil.Therefore traditional type really connects the waste disposal method of burning, and the obnoxious flavoures such as Dioxins that produced are the great technical barriers that is difficult to administer.The filling type method is arranged again, and this method floor space is very big, and expense is higher, has not only wasted a large amount of land resources, does not also solve problem of environmental pollution fully; Composting process is handled, organic utilization is incomplete, fertilizer composition complexity, some unwanted bacterias can not get dealing carefully with and can produce secondary pollution, for example also have a lot of sorting process domestic refuses be made into solid-fuelled known technology show have sub-elect the brick tile fragment, sandstone, glass fragment, leaf of vegetable etc., the organic waste composition of low heat energy all sorting gone out, what have has been utilized, the quilt that has has been thrown away, and this does not meet the needs of handling domestic refuse fully, elsewhere, no matter be mechanical sorting or other method sorting, generally speaking, the article that sub-elect are many more, and cost is just big more.When external temperature reached more than 0 ℃, all domestic refuses all contained perishable foodstuff even more noteworthy, disposed as untimely, anywhere or anytime all can be mouldy, rotten, smelly, and it is long to be difficult for the storage period, and the link that is difficult for many technology is handled domestic refuse.

Summary of the invention:

Deficiency in view of above-mentioned prior art existence, the purpose of this invention is to provide a kind of method of utilizing the mixing house refuse with fire coal synthetizing solid fuel, make domestic rubbish disposal more perfect, the solid fuel that makes is easy to store, non-secondary pollution and manufacture craft simple, domestic refuse can be utilized effectively, and saves the energy.

The object of the present invention is achieved like this: contained metal in the domestic refuse is sorted out, carry out simple dehydrating according to the refuse moisture size; B, then all remaining rubbish are inserted garbage grinder and carry out pulverization process, disposable finishing, the rubbish powder of pulverizing out generally reaches 50～60 order fineness; C, add general coal-fired powder 20%～35% with above-mentioned rubbish powder is per ton, and then add the yellow clay powder of 10-20%, these three kinds of powder are directly entered in the mixer stir, after stirring, directly enter die mould in the roller forming press again, extrude 5～6 centimeters spherical shape material; D, round spherical directly the inserting that will extrude are carried out drying in the drying machine, temperature is at 150-250 ℃, and when reaching drying effect fully, the spherical shape material with oven dry is presented in the broken machine of crocodile again, the grain that breaks into 1～2 centimeter is block, and the grain piece that crocodile is broken 1～2 centimeter is promptly made solid fuel.

This solid fuel can be supplied with existing fuel-burning power plant generating usefulness, can also supply with heating boiler and use.

After making this solid fuel ignition, be able to utilize fully again, the useless boiler ash sediment that has burnt is got back, the boiler ash sediment that will give up again enter be ground in the pulverizer Powdered, again with 1 ton boiler ash sediment powder, add 30% No. 500 cement, add 20% lime powder again, after mixer stirs, with 80～100 tons hydropress the boiler ash sediment raw material that these mix directly is pressed into material of construction, as square brick etc.

The technology of the present invention effect is that domestic rubbish disposal is more perfect, and the metal sorting in domestic refuse was gone out, all the other domestic refuses all can obtain utilizing; It can be not less than the heat energy that general fire coal sends with general coal-fired than beautiful; Be convenient to store, transport the non-secondary pollution problem; In addition, invest little, equipment is simple, not limited by the place, and is easy and simple to handle; Help the development and utilization of the energy, save energy.

Detail of the present invention is provided by following examples:

Embodiment 1

After domestic waste enters treatment plant, at first the rubbish parcel bag is broken with machinery, cooperate artificial separation, mainly the contained metal of rubbish is selected, can then all remaining rubbish be inserted pulverizer and carry out pulverization process, disposable finishing according to the dehydration of rubbish humidity size, be ground into Powderedly, reach 50～60 order fineness.The rubbish powder of Fen Suiing in this way, can contain high heating value to all domestic refuses and low-calorie solid combustible can mix uniformly, make those non-flammable article brick tile fragments, sandstone, glass fragment etc. also can be played a role, it can play the support effect when burning, ventilative making good use of makes those combustiblematerialss can reach hundred-percent burning; Calculate in 1 ton of ratio with the rubbish powder of pulverizing out, rubbish powder per ton adds 250 kilograms general fire coal (calorific value 3000 kilocalories-4000 kilocalories fire coal) powder, play combustion-supporting effect, the yellow clay powder that adds 150 kilograms again, these three kinds of powder mixes after stirring, stirrer are inserted the spherical shape that the roller forming press extrudes 5～6 centimeters together, through the roller dryer oven dry, last grain bulk of breaking into 1～2 centimeter again through the broken machine of crocodile is preserved in the woven bag of packing into then.

Embodiment 2

Basic identical with embodiment 1 method, 300 kilograms general coal-fired powder is just added in difference at rubbish powder per ton, adds 140 kilograms yellow clay powder again.

After making this solid fuel ignition, be able to utilize fully again, can formulate with applying unit and reclaim agreement, the useless boiler ash sediment that has burnt is got back, the boiler ash sediment that will give up again enter be ground in the pulverizer Powdered, again with 1 ton boiler ash sediment powder, add 30% No. 500 cement, add 20% lime powder again, after mixer stirs, with 80～100 tons hydropress the boiler ash sediment raw material that these mix directly is pressed into material of construction---square brick etc., can suppress according to demand, the purpose of making is mainly the solid nuisance that contains in the waste slag that has burnt like this, all be fixed in the square brick, this has solved fully, and harmful solids can reach emission request in the rubbish slag after the burning.The brick of making can be sold the increase sales revenue, and it also brings economic benefit and social benefit simultaneously.
