Embodiment 1

[0022] Embodiment one: the method for making brick with household garbage

[0023] Squeeze the domestic waste through a double-roller pulverizer, and sieve it with a coarse sieve with an aperture of 1cm. After screening, the waste is divided into combustible waste and non-combustible waste;

[0024] Weigh 40 parts of non-combustible garbage, 12 parts of coal gangue, and 20 parts of clay according to the proportion, crush them into particles below 1.5 cm, mix them, add 25% of the water in the mixture, mix them evenly, and dry them under a pressure of 9 to 10 MPa. After being pressed, it is made into bricks, and then enters the tunnel kiln for preheating, and gradually raises the temperature to 800°C; the combustible garbage is incinerated and gasified in the gasification furnace, and the gas generated by gasification is passed into the tunnel kiln roasting area as fuel, and is heated at 1050 The adobe is fired at ℃ for 7-8 hours, and then cooled naturally out of the kiln.

[0026] Embodiment two: the method for making brick with household refuse

[0027] Squeeze the domestic garbage through a double roller crusher, and then sieve it with a coarse sieve with an aperture of 1 cm. After screening, the garbage is divided into combustible garbage and non-combustible garbage; 70 parts of non-combustible garbage, 20 parts of coal gangue, and 40 parts of clay Parts, weighed according to the proportion, crushed into particles below 1.5cm, mixed, then added 30% water of the mixture, mixed evenly, dry pressed under 10-12MPa pressure to make bricks, and then entered the tunnel kiln for preheating, and gradually raised the temperature to 900°C; incinerate and gasify the combustible waste in a gasification furnace, and the gas produced by gasification is passed into the tunnel kiln roasting area as fuel, and the bricks are fired at 1100°C for 8 hours, and then cooled naturally to leave the kiln.

Embodiment 3

[0028] Embodiment three: the method for making brick with household garbage

[0029] Squeeze the household garbage through a double-roller pulverizer, sieve it with a coarse sieve with an aperture of 1cm, and divide it into combustible garbage and incombustible garbage after sieving; divide 42 parts of non-combustible garbage, 18 parts of coal gangue, and 22 parts of clay , weighed according to the proportion, crushed into particles below 1.5cm, mixed, then added 22% water of the mixture, mixed evenly, and dry pressed under 11MPa pressure to make bricks; combustible garbage was incinerated and gasified in a gasifier, and the The gas produced by gasification is passed into the tunnel kiln as gas fuel, and the adobe is fired at 1070°C for 6 hours, and then cooled naturally to leave the kiln.

Abstract

The invention relates to a method for manufacturing bricks by using household garbage. The method comprises the following steps of: crushing and mixing 40 portions to 70 portions of non-combustible garbage, 10 portions to 20 portions of coal gangue and 20 portions to 40 portions of clay, adding 20 percent to 30 percent of water into the mixed material, mixing evenly and preparing adobes by dry pressing under the pressure; placing the adobes into a tunnel kiln; introducing the gas generated by the gasified burnable garbage in a gasifying furnace into the tunnel kiln to be as fuel; and obtaining the adobes by roasting at the temperature of 1050 to 1100 DEG C. The method can adopt the gas generated by the burnable garbage after gasification as fuel for high-temperature burning, fully realizes the effective utilization of the household garbage and reduces the production cost of the brick; the material contains the coal gangue which can sinter by self-combustion under high temperature and provide heat; and the method has short production time, simple technique and easy operation, saves energy and is beneficial to environmental protection. By inspection, the pressure resistance of the brick can be up to 8MPa.

Description

1. Technical field: [0001] The invention belongs to the technical field of sintered bricks for construction, and in particular relates to a method for making bricks from domestic garbage. 2. Background technology: [0002] At present, in the preparation process of sintered bricks, it is a relatively common method to add an appropriate amount of coal to clay, mix and stir with water to make bricks, and then roast them. Although this method has reduced the roasting time and saved a certain amount of coal, it still has the disadvantage of a large amount of coal due to the need to add about 150 to 180 grams of coal in each brick. [0003] With the development of economy, the progress of society, the increase of urban population and the continuous improvement of people's living standards, the amount of domestic waste produced every day will inevitably increase. According to reports, the annual output of urban domestic waste per capita in my country reaches 400kg / (person-year) at...
