Abstract

The invention discloses a method for preparing solid fuel with animal excrement as a main raw material. The solid fuel is prepared from 30-85 parts of animal excrement, 2-30 parts of rutile, 2-20 parts of ilmenite, 2-50 parts of aluminosilicate ore powder, 2-30 parts of potassium nitrate, 2-40 parts of calcium carbonate and auxiliary materials which comprise organic silicon quaternary ammonium salt, borneol, lygodium japonicum, a dispersing agent, alcohol group, an alcohol group fuel heating agent, strontium and industrial paraffin. The method comprises the following steps of: firstly, placing the animal excrement into a sterilizing pot and sterilizing at the temperature of 100 DEG C; after atomizing for deodorizing and drying by utilizing ultrasonic waves, grinding into powder for later use; sequentially adding all raw materials into a mixing machine and uniformly stirring according to the proportion; charging into a squeezing granulator and granulating; and charging particle materials into a hydraulic machine and pressing into a solid fuel finished product with honeycomb holes. The invention has the advantages of low cost, no pollution and longer combustion time compared with the common coal and can be used for various occasions instead of common coal.

Description

With animal excrement is that main raw material prepares solid-fuelled method

Technical field

The present invention relates to solid fuel, relate to especially that a kind of can to substitute coal-fired be that main raw material prepares solid-fuelled method with animal excrement.

Background technology

Pollution makes people more and more pay attention to environment protection, and have existed since ancient times and dryout excrement heating, and after liquid was separated from ight soil, argol just and the ight soil of free from extraneous odour, particularly herbivore; Dejecta fuel does not contain sulphur, does not contain during burning to discharge the gas that makes Global warming, helps protecting atmospheric environment.Utilization to animal excrement fuel at present only rests on initial stage, does not carry out commercial scale production.

Summary of the invention

The object of the present invention is to provide a kind of is that main raw material prepares solid-fuelled method with animal excrement, and this method can be carried out commercial scale production, and finished product calorific value height can substitute coal fuel.

For achieving the above object, the present invention can take following technical proposals:

Of the present invention is that main raw material prepares solid-fuelled method with animal excrement, and it is to be prepared from according to the following weight parts proportioning by major ingredient animal excrement, rutile, ilmenite, silico-aluminate ore powder, saltpetre, lime carbonate and auxiliary material organosilicon quaternary ammonium salt, borneol, Spora Lygodii, dispersion agent, alcohol radical, alcohol-group fuel gain of heat agent, strontium, industrial paraffin:

Proportioning: animal excrement 30-85 part; Rutile 2-30 part; Ilmenite 2-20 part; Silico-aluminate ore powder 2-50 part; Saltpetre 2-30 part; Lime carbonate 2-40 part; Organosilicon quaternary ammonium salt 1-12 part; Borneol 1-6 part; Spora Lygodii 1-10 part; Dispersion agent 1-8 part; Alcohol radical 1-8 part; Alcohol-group fuel gain of heat agent 0.1-0.8 part; Strontium 0.08-0.6 part; Industrial paraffin 0.1-0.7 part;

Preparation:

The first step places in the cannery retort sterilization under 100 ℃ of temperature with animal excrement, utilize ultrasonic atomization deodorizing, oven dry after, be ground to Powdered standby;

Second step according to said ratio, joined each raw material in the mixing machine successively and to stir, and sent into granulation in the Squeezinggranulator, obtained the work in-process granule materials after the dry cooling of particulate material; The work in-process granule materials is sent in the hydropress,, be pressed into the solid fuel finished product that has honeycomb hole and get final product according to specification requirement.

The invention has the advantages that when the solid fuel that adopts animal excrement (animal excrement such as ox, sheep, horse, chicken all can) and add the several mineral materials preparation uses longer than coventional type coal-burning time, can replace common moulded coal to be used in various occasions, raw material and cheap for manufacturing cost, pollution-free during burning, belong to emerging fuel with development prospect.The solid fuel of the present invention's preparation is divided into four-stage relay-type continuous burning, and its calorific value can reach about the 3000-6000 kilocalorie; This solid fuel is from entering burner hearth to all burnt, experience the moisture evaporation stage, volatile matter catches fire the stage, mineral substance combustion phases and burning the stage, promptly after solid fuel enters burner hearth, moisture is evaporated gradually, compounding substances constantly absorbs heat, volatile matter is separated out thereupon, after reaching burning-point, volatile matter takes fire, and (combustionvelocity of volatile matter is very fast, general only account for this solid fuel whole combustion time about 1/10), at this moment the high-melting-point combustible mineral in the fuel reaches burning-point, and violent burning discharges a large amount of heats (solid-fuelled combustionvelocity and the degree of burning depend primarily on this stage); Burn the stage, this stage will make combustiblesubstance burn down as far as possible, finishes a relay-type stage continuous burning, reaches the temperature of high combustion point, with the reduction heat loss due to incomplete combustion, raises the efficiency.

The present invention with animal excrement as main raw material, added cheap commercially available raw mineral materials rutile, ilmenite, silico-aluminate ore powder, saltpetre, lime carbonate and auxiliary material organosilicon quaternary ammonium salt, borneol, Spora Lygodii, dispersion agent, alcohol-group fuel, alcohol-group fuel gain of heat agent, strontium, industrial paraffin simultaneously, wherein the dispersion agent in the auxiliary material can well scatter raw material uniformly, both can make to have good consistency between the different material, prevent caking again; Alcohol-group fuel wide material sources, and burning the most completely are future cleaning, environmental protection and the most potential fuel; Strontium is the trace element that occurring in nature extensively distributes, and it can make solid fuel well finish continuous burning, thereby makes it reach the highest burning-point; Alcohol-group fuel gain of heat agent can change the fuel value of melt, because this solid fuel does not have the fixed burning-point, the scope that an ignition temperature is only arranged, the burning-point of incendiary volatile matter will be well below the burning-point of mineral substance at first, the mineral substance of these heterogeneities can form a kind of eutectic at a certain temperature, this eutectic is when the burning-point state, the performance that other high-melting-point materials of fusion are arranged, thereby changed the fuel value of melt, finish a relay-type stage continuous burning, make it reach the temperature of high burning-point.
