Abstract

The utility model relates to a carbon dioxide generator. The utility model is characterized in that a reaction barrel 4 is arranged in a water bath barrel 5 which is connected with a thermometer 3 and a fluviograph 12. When water in the water bath barrel is heated up above 30DEG C, ammonium bicarbonate in the reaction barrel is heated and broken up, so carbon dioxide gas and ammonia gas are generated; the ammonia gas is dissolved in water in an ammonia barrel 15 and turned into ammonia.

Description

Carbon dioxide generator

The utility model relates to a device for generating carbon dioxide in a sunlight greenhouse.

The cultivation of crops in sunlight greenhouses and plastic greenhouses has become a popular technology in modern agricultural production. However, in a closed greenhouse, the concentration of carbon dioxide in the air is very low, which cannot meet the requirement of photosynthesis of crops, and directly influences the yield and quality of the crops. Meanwhile, the content of nitrogen compounds (nitrogen fixation) required by the growth of crops in the greenhouse is far from meeting the growth requirement of the crops, and the yield increase of the crops is influenced. At present, many methods and devices for artificially increasing carbon dioxide in greenhouse are available, but it is more common to utilize ammonium bicarbonate (ammonium bicarbonate) and sulfuric acid to generate carbon dioxide gas through chemical reaction, thereby meeting the photosynthesis requirement of crops. The method and the equipment have to store a certain amount of sulfuric acid and ammonium bicarbonate in advance, which brings great inconvenience to users in remote rural areas in raw material purchase, transportation, storage and operation. Moreover, the equipment is complex, the operation requirement is high, and the production cost is high.

The utility model aims to provide a carbon dioxide generator with simple structure, convenience and practicability for overcoming the defects in the prior art.

The technical solution for realizing the above purpose is as follows: a reaction barrel is arranged in the water bath barrel, and the water bath barrel and the reaction barrel are both provided with covers. The outer side of the water bath barrel is also provided with a thermometer and a water level gauge. The water bath barrel is provided with a water inlet and a drain valve, and the reaction barrel is communicated with a dissolved air ring in the ammonia water barrel through a gas pipe. A heater is also arranged below the reaction barrel.

The attached drawing is the structure schematic diagram of the utility model.

The present invention will be described with reference to the accompanying drawings and examples.

Example 1:

as shown in the attached drawing, the utility model discloses mainly constitute by water bath bucket 5, reaction barrel 4 and aqueous ammonia bucket 15, wherein, 5 upper portions of water bath bucket are equipped with water inlet 6, relief port 11 and lid 7, and its lower part is equipped with drain valve 1, and thermometer3 and fluviograph 12 are connected with water bath bucket 5 respectively. The reaction barrel 4 with a cover 18 is arranged in the water bath barrel 5, the cover 18 is connected with a gas pipe 10, a valve 8 is arranged on the gas pipe 10, and the gas pipe 10 is connected with a gas dissolving ring 16 with a small hole at the bottom in the ammonia water barrel 15. The upper part of the ammonia water barrel 16 is provided with a cover body 14, the lower part thereof is provided with a drain valve 17, and a gas guide pipe 13 connected with the cover body 14 is communicated with the gas exhaust pipe 9 at the upper part.

When in use, the required ammonium bicarbonate (NH) is put into the reaction barrel 4₄HCO₃) And 5% water is added, and then hot water is poured into the water bath barrel 5. When the temperature is over 30 deg.c, the ammonium bicarbonate is heated to decompose into carbon dioxide, ammonia and water, and the chemical reaction equation is shown.

The generated carbon dioxide gas and ammonia gas enter an ammonia water barrel 15 through a gas transmission pipe 10 and a gas dissolving ring 16, and the ammonia gas (NH)₃) Dissolving in water to generate carbonized ammonia water (NH)₃·H₂O); the carbon dioxide gas is emitted out of the water surface and is dissipated into the greenhouse through the small holes of the air duct 13 and the exhaust pipe 9 so as to meet the requirement of cropsCarbon dioxide required for photosynthesis.

Example 2: a heater 2 is arranged below the reaction barrel 4, and the heater 2 can be heated by electric heating or solar cells as long as the water in the water bath barrel 5 can be heated to be above 30 ℃.

Example 3: the solar water heater is directly utilized, water heated to more than 30 ℃ is input into the water bath barrel 5 from the water inlet 6 through a pipeline, and then the ammonium bicarbonate can be directly heated and decomposed.

The utility model overcomes use sulphuric acid not enough among the prior art, utilize ammonium bicarbonate to be heated the characteristic of decomposition and heat it, produce the indoor required carbon dioxide gas of canopy, have characteristics such as energy saving, non-staining environment, convenient to use, novel structure, be fit for the indoor installation of canopy and use.
