Embodiment Construction

[0012] The specific implementation manner of the present invention will be described below with reference to the accompanying drawings.

[0013] The specific embodiment of the present invention is to carry out as follows:

[0014] a. Take seawater as raw material, add ammonia gas and carbon dioxide gas into seawater, make the salt compound in seawater fully mix with ammonia and carbon dioxide gas, generate ammonia-carbon composite water, the addition amount of described ammonia gas is the salt compound in seawater 0.45 to 0.55 of the mass; the added amount of the carbon dioxide gas is 0.7 to 0.75 of the mass of the salt compound in seawater;

[0015] b. Add ammonium nitrate to the ammonia-carbon composite water and fully mix the two. The amount of ammonium nitrate added is 0.56 to 0.65 of the quality of the salt compound in seawater to generate a nitrogen fertilizer nutrient solution.

[0016] Specifically, it can be realized by equipment as shown in 1. It is provided with a ...

Abstract

The invention discloses a method and equipment for producing plant nitrogen fertilizer nutrient solution by taking seawater as a raw material, which achieves zero emission and is favorable for the environment. The method is characterized by comprising the following steps: a, taking seawater as the raw material, adding ammonia gas and carbon dioxide gas in the seawater, and enabling slat compounds in the seawater to be fully mixed with the ammonia gas and the carbon dioxide gas to generate ammonia-carbon compound water, wherein the adding amount of the ammonia gas is 45 to 55 percent of the mass of the salt compound in the seawater, and the adding amount of the carbon dioxide gas is 70 to 75 percent of the mass of the salt compound in the seawater; and b, adding ammonium nitrate in the ammonia-carbon compound water and enabling ammonium nitrate and the ammonia-carbon compound water to be fully mixed, wherein the adding amount of ammonium nitrate is 56 to 65 percent of the mass of the salt compound in the seawater, so as to generate the nitrogen fertilizer nutrient solution.

Description

technical field [0001] The invention relates to a method for processing and utilizing seawater, in particular to a method and equipment for producing plant nitrogen fertilizer nutrient solution with seawater as a raw material, which is zero-emission and beneficial to the environment. Background technique [0002] 71% of the earth's surface area is ocean, and seawater is the largest material resource on earth, so humans have long begun to use seawater. Most of the various elements in seawater exist in the form of salt compounds. The salt content of seawater in different regions of the world's oceans is also different (each region has accurate detection data), such as the seawater near the equator. The salt content can reach up to about 4%, and the salt content of seawater near the estuary of large rivers on land is only about 3%. In 1872, the world-recognized famous chemist Dittmar Dittmar published the detection report of "substances contained in seawater". Since then, all ...
