Abstract

An internal-combustion material containing chromium dregs in the brick production and its application. It features that it uses chromium dregs 5-90%, material containing combustible component 10-95% and other material 0-80% to become a material containing a certain heat giving quantity through processing and compounding, and this internal-combustion material may be applied to the production of building material such as brick and tile. This invention is simple and convenient in implementation, can dispose toxic chromium dregs in great quantity, and may produce definite environmental benefit and economic benefit after implementation.

Description

The internal combustion material and the application of containing chromium slag composition during brick and tile are produced

The present invention relates to the internal combustion material and the application thereof of containing chromium slag composition in the brick and tile production.

Chromium residue discharged during the chromium slag is produced is a kind of harmful industrial waste, and its quantity discharged is bigger, and the old slag that stack various places has reached more than 1,000,000 tons, domestic existing tens of kinds of resolutions, and wherein chromium slag brick and tile is a kind of effective resolution.This promptly achieved success before one, 20 year, see that " metallurgical industry waste residue treatment process with utilize scientific and technological achievement compilation " 1985 P.249, because chromium slag discharging factory adheres to different industries separately with brickmaking factory, still a large amount of work need be done for the cooperation of coordinating both sides, the method that original brick making industry is utilized the chromium slag need be improved for this reason.

The purpose of this invention is to provide a kind of very simple and direct, the internal combustion material of the containing chromium slag composition of method preparation easily, its main application is a brick and tile, can reduce Bricks and Tiles Plant's fuel consumption and production cost, processing and utilizing chromium slag in a large number, can retrain the behavior of the parties concerned with economical means, the safety of accomplishing the chromium slag, low-cost processes.

The present invention is specifically described as follows:

The internal combustion material of containing chromium slag composition, its component proportioning is the chromium slag: combustible material: other material=5-90%:10-95%:0-80%.

The chromium slag is preferably selected for many years the chromium slag displayed of weathering for use in the component; Combustible material comprises: mud coal, coal, cinder, flue dust, coal gangue, coke tar refuse, smelting slag, sulfide, the material that contains flammable composition, have the combustion heating amount such as bits, waste oil not; Other material means and can make 6 valency chromium be reduced to the material of chromium at a low price under certain reaction conditions.

Difference according to the various places production environment, the preparation of mixing combustible material in this, can with the chromium slag through or without with component in after other material detoxifcation reaction, become product with the combustible material mixing match again, supply with the Bricks and Tiles Plant and mix in the clay, make full internal combustion or part internal burned brick unbaked tile in different ratios.

Since in mix combustible matl and can reduce production costs, fuel economy so it is out of trade to remove brick and tile, also can adopt in other building material industry such as cast stone, rock wool, cement, light ceramic and the Ceramic Production.

The method system of existing chromium slag brick and tile uses chromium slag and clay preparation brick and tile base separately, its disadvantage is: brick and tile enthusiasm is not high, incorporation is not easy to control, because the chromium slag does not spend money on, the transporter can arbitrarily topple over and causes environmental pollution (existing example can look into), and a large amount of slags that produce in chromium slag discharging factory or near the plant produced, flue dust is owing to contain the easy-to-sell goods that certain flammable composition becomes brick field again, spend money on by brick field, allocate adobe into and make interior combustible material to reduce fuel consumption and production cost, needs according to the various places brick field, adopt the present invention to make the interior combustible material of containing chromium slag composition, can reach certain thermal value, oversize material is through broken in the material, and brick field is easy to use, and product price is low, can retrain chromium slag discharging factory and the relation of utilizing factory with economical means, solve the drawback of existing method, the phenomenon that particularly can control incorporation effectively and stop to topple on the way reaches safety, utilize the purpose of chromium slag reliably.

Embodiment one:

Weight ratio: flue dust 50%, chromium slag 25%, reducing slag 25%, reducing slag and chromium slag are added the water reaction through amalgamator, to mix the flue dust mixing again and be made into, thermal value is the material of 6.5MJ/kg.

Embodiment two:

Weight ratio; Zinc is smelted perpendicular jar slag 70%, chromium slag 30%, and zinc can slag and broken the mixing and stirring of chromium ground-slag are mixed with the material that thermal value is 5.1MJ/kg.

Claims
