Description
Technical Field
The invention relates to the technical field of calcium hydroxide production, in particular to a production process of a novel calcium hydroxide blender.
Background
Calcium hydroxide, commonly known as hydrated lime or slaked lime, is a slightly water-soluble white solid, the aqueous solution of which is often referred to as limewater.
The slaked lime can be widely applied to the industries of water treatment, leather industry, papermaking, industrial boilers, desulfurization, deacidification, chemical building materials and the like, has a very wide application range and is very large in use amount.
The traditional era of the original lime slaking process is changed into an era of continuous production by production equipment and goes through a plurality of development cycles due to the change of the lime deep processing process, but the quality of the slaked lime produced by the prior art is still poor and the production efficiency is low.
Disclosure of Invention
The invention aims to solve the technical problem of overcoming the difficulties and provides a production process of a novel calcium hydroxide blender with good calcium hydroxide quality and high production efficiency.
1. In order to solve the technical problems, the technical scheme provided by the invention is as follows: the production process of the novel calcium hydroxide blender comprises the following steps:
(1) putting the stone into a crusher to be crushed to obtain smaller stone fragments;
(2) calcining the stone fragments in a lime rotary kiln to obtain quicklime, wherein the calcining temperature is kept at 1100 DEG C
Above, the duration of combustion is four hours;
(3) putting quicklime into a hydration reactor for full reaction to obtain calcium hydroxide;
(4) putting the calcium hydroxide into a 20-mesh vibrating screen for vibration filtration to remove impurities in the calcium hydroxide;
(5) drying the calcium hydroxide with impurities removed in a dryer;
(6) and (3) putting the dried calcium hydroxide into a grinder to grind.
As an improvement, the stone is limestone.
The invention has the following advantages: the calcining temperature in the step (2) is kept above 1100 ℃, the burning duration is four hours, and calcium carbonate in the stone can be fully reacted to generate quicklime; the calcium hydroxide in the step (4) is put into a 20-mesh vibrating screen for vibration filtration, so that impurities in the calcium hydroxide can be removed, and the purity of the calcium hydroxide is higher; and (6) putting the calcium hydroxide into a grinder for grinding, so that the calcium hydroxide is more convenient for people to use.
Detailed Description
The present invention is described in further detail below.
In the concrete implementation of the invention, the production process of the novel calcium hydroxide blender is characterized in that: the method comprises the following steps:
(1) putting limestone into a crusher to be crushed to obtain smaller limestone fragments;
(2) calcining limestone fragments in a lime rotary kiln to obtain quick lime, wherein the calcining temperature is kept at 1100 DEG C
The combustion duration is four hours, so that the limestone can react more fully;
(3) putting quicklime into a hydration reactor for full reaction to obtain calcium hydroxide;
(4) putting the calcium hydroxide into a 20-mesh vibrating screen for vibration filtration to remove impurities in the calcium hydroxide and ensure that the purity of the calcium hydroxide is higher;
(5) the calcium hydroxide with impurities removed is put into a dryer for drying, and the moisture in the calcium hydroxide is removed, so that the calcium hydroxide is more convenient to store and transport;
(6) and (4) putting the dried calcium hydroxide into a grinder, grinding the calcium hydroxide, weighing and bagging.
The chemical reaction formula of the invention is as follows:
(limestone) CaCO3 → (quicklime) CaO + CO 2;
(quicklime) CaO + (water) H2O → (calcium hydroxide ca (oh) 2.
The present invention and its embodiments have been described above, but the description is not limitative, and the actual structure is not limited thereto. It should be understood that those skilled in the art should understand that they can easily make various changes, substitutions and alterations herein without departing from the spirit and scope of the invention as defined by the appended claims.
Claims (2)
