Abstract
The present invention discloses granular carbon dioxide gas fertilizer and a preparation method thereof, which belongs to fertilizer for producing carbon dioxide and a preparation method thereof. The gas fertilizer is prepared from the following raw materials according to the parts by weight: 2 to 2.2 parts of aluminum sulfate, and a part of light calcium carbonate. The granular carbon dioxide gas fertilizer has the advantages of stable performance, safe and convenient preservation, transportation and operation, etc., and has no toxic effect on human bodies, animals and soil plants. The preparation method provided by the present invention has the characteristics of simple operation, high raw material utilization rate, etc.
Description
Affiliated technical field
The invention belongs to the preparation method of the fertilizer that produces carbonic acid gas.
Background technology
Carbon-dioxide gasfertilizer is the indispensable a kind of fertilizer of modern protection ground cultivation; the general deficiency that adopts the method for producing carbonic acid gas to replenish carbonic acid gas in the booth; the raw material that uses has varied; CN01139982 discloses a kind of preparation method of CO 2 gas fertilizer used in agricultural greenhouse; with ammonium hydrogencarbonate and sal enixum uniform mixing in proportion, the nature chemical reaction generates vitriolate of tartar, sulfate of ammoniac, carbonic acid gas and water under the room temperature.More than Pei Fang shortcoming is; 1. sal enixum acidity is forced to use and is not very safe, and 2. bicarbonate of ammonia character is emitted ammonia unstable easily the decomposition.Have many peasant households to use dilute sulphuric acid and bicarbonate of ammonia to react and produce carbonic acid gas, though method is simple, the vitriol oil is very dangerous in dilution and use, and gas is with acid easily in reaction process, and crop is caused in various degree injury.
Summary of the invention
The preparation method who the purpose of this invention is to provide a kind of stable performance, carbon-dioxide gasfertilizer safe and convenient to use.
Technical scheme of the present invention is that a kind of preparation method of granular CO 2 gas fertilizer is characterized in that: comprise the steps
A. Tai-Ace S 150 2-2.2 weight part is got in raw materials pretreatment, and light calcium carbonate 1 weight part is crushed to 100 orders-120 order with Tai-Ace S 150, and described Tai-Ace S 150 is Al
2(SO

318H
2O,
B. light calcium carbonate is heated to 250-400 ℃ and adds the Tai-Ace S 150 that 2-2.2 doubly measures then, the even Tai-Ace S 150 heat absorption of short mix is attached on the surface with light calcium carbonate and forms particulate state, realize granulation, material is transferred in the fluidized-bed lowers the temperature then, discharging packing when temperature is reduced to 20-60 ℃.
Using method: can put it into during use and add little water in the keg and can react, if very wetly on the ground also can directly be sprinkled upon on the ground, this product suction can be emitted pure CO
2, resultant of reaction is starchiness or granular.
This reaction for two hydrolysis reaction net reactions that Tai-Ace S 150 and lime carbonate and water carry out is; Al

3+ 3CaCO
3+ 3H
2O=3CaSO
4+ 2Al (OH)
3+ 3CO

Because Tai-Ace S 150 is heated to more than 90 ℃ and is viscosity, should not operate, and two kinds of materials at high temperature can react by the crystal water that carries, loss of effective components is fallen, to add the Tai-Ace S 150 short mix then even so earlier light calcium carbonate is heated to 250-400 ℃ in preparation method of the present invention, thereby the Tai-Ace S 150 heat absorption is attached on the surface with light calcium carbonate and realizes granulation in mixing.Granulous gas fertilizer is convenient to preserve and use, and can put it into the interior little water that adds of a keg during use can react, and emits pure CO
2Resultant of reaction is starchiness or granular, and people and animals and soil are had no side effect.
The preparation method of granular CO 2 gas fertilizer disclosed by the invention has simple to operate, characteristics such as raw material availability height.The granular CO 2 gas fertilizer that this method is made have stable performance, safe and convenient to use, to advantages such as people and animals and the toxic actions of soil thing.
