Problems solved by technology

Due to the extremely complex composition of semi-dry desulfurization ash, which is composed of desulfurization agent, desulfurization product and fly ash and other components, and the calcium sulfite in desulfurization ash is very unstable in the process of being used, so most of them are stacked and Disposal is mainly used for disposal, which not only causes waste of resources, but also causes damage to the surrounding environment

Embodiment 1

[0012] The product is a standard brick

[0013] Raw material weight ratio: 50% desulfurization ash, 10% iron tailings, 26% stone chips, 14% cement.

[0014] Send the above raw materials into the mixer according to the ratio for mixing, and then send them to the hopper of the main machine through the wet mixing belt, and form them through the vibration and compression of the material of the main machine to produce desulfurized ash blocks, put them into the curing kiln for steam curing, and finally bundle the gas Package.

Embodiment 2

[0016] The product is colored floor tiles

[0017] Raw material weight ratio: 30% desulfurization ash, 22% iron tailings, 32% stone chips, 16% cement.

[0018] Send the above raw materials into the mixer according to the ratio for mixing, and then send them to the hopper of the main machine through the wet mixing belt, and form them through the vibration and compression of the material of the main machine to produce desulfurized ash blocks, put them into the curing kiln for steam curing, and finally bundle the gas Package.

[0019] The product made from the above ingredients and methods can be used as the base material for colored floor tiles, and the product made in Example 1 can be used as a fabric for colored floor tiles to make more beautiful and durable colored floor tiles.

Embodiment 3

[0021] The product is colored floor tiles

[0022] Raw material weight ratio: 40% desulfurization ash, 12% iron tailings, 30% stone chips, 18% cement.

[0023] Send the above raw materials into the mixer according to the ratio for mixing, and then send them to the hopper of the main machine through the wet mixing belt, and form them through the vibration and compression of the material of the main machine to produce desulfurized ash blocks, put them into the curing kiln for steam curing, and finally bundle the gas Package.

Abstract

The invention discloses a desulfurization ash building block, which is mixed and prepared by the following materials in percentage by weight: 30-65% of desulfurization ash, 0-22% of iron tailings sand, 12-32% of aggregate chips, 12-18% of cement. The desulfurization ash building block can be made to be a standard building block or a colorful floor tile. 70-80% of desulfurization ash and 20-30% of cement are made to be desulfurization ash ceramsite and then are made to be a desulfurization ash hollow building block. The desulfurization ash building block can be made to be a series of wall building materials of different specifications through extrusion and vibration compaction, thus changing the waste material into things of value, being remarkable in environment-friendly and energy-saving effects, heat preservation effects, fireproof effects and soundproof effects, anti-abrasive and corrosion resistant, free of later maintenance, and low in producing and using cost.

Description

technical field [0001] The invention relates to a building block, in particular to a block using desulfurized ash as a raw material. Background technique [0002] As my country controls and reduces SO 2 With the continuous increase of emissions, flue gas desulfurization has entered a stage of rapid development. With the successive installation of desulfurization devices, more and more desulfurization products are produced, and the comprehensive utilization of desulfurization ash has become an urgent problem to be solved. Due to the extremely complex composition of semi-dry desulfurization ash, which is composed of desulfurization agent, desulfurization product and fly ash and other components, and the calcium sulfite in desulfurization ash is very unstable in the process of being used, so most of them are stacked and Disposal is mainly used for disposal, which not only causes waste of resources, but also causes damage to the surrounding environment.
