Description

Technical Field

[0001] The utility model relates to the technical field of spray carbonization equipment, and more specifically to the technical field of small-sized spray carbonization devices for experiments. Background Art

[0002] The carbonization device is the main equipment for preparing industrial raw materials such as light calcium carbonate and soda ash. Under the existing technical conditions, the common experimental carbonization devices mainly include stirring type, bubbling type and super gravity type. Among them, stirring type and bubbling type carbonization devices are widely used due to their small size and convenient control of reaction conditions. However, this type of carbonization device has the disadvantages of poor gas-liquid contact effect, insufficient carbonization, large CO2 consumption, long reaction time, and low efficiency. The super gravity carbonization device has a large gas-liquid contact area and sufficient reaction, but it has a complex structure, a large amount of raw materials, difficult cleaning, and low CO2 utilization. Existing patents disclose the following technologies:

[0003] The patent with the publication number CN100450932C and the patent name "A Carbonization Process of Nano Calcium Carbonate" discloses the following content: A carbonization process of nano calcium carbonate belongs to the technical field of nano powder preparation. It is characterized in that a calcium hydroxide solution with a concentration of 8-12% (m) and a density of

[0004] 1.04-1.07g / cm 3 , the starting temperature is 15-20°C, poured into an intermittent stirred reactor, and after sufficient stirring, the slurry is started to circulate, and the carbon dioxide mixed gas is introduced into the circulation pipeline and the strong shear mixer to mix strongly with the circulating suspension, and enters the buffer tank or reactor through the circulation pipeline. When the pH of the suspension drops to 7-7.5, the reaction is stopped. The reaction time of the entire carbonization process lasts 30-70 minutes, and the terminal temperature is in the range of 30-40°C. The process flow provided by the present invention can achieve a higher reaction rate. In the strong shear mixer, the bubbles are fully crushed, and the gas-liquid-solid three-phase is highly mixed, which solves the defects of slow gas-liquid-solid three-phase mass transfer rate and low contact efficiency in the traditional carbonization process of producing nano calcium carbonate, and shortens the reaction time. This patent is a stirring carbonization device, which has the above-mentioned defects of a stirring carbonization device.

[0005] Therefore, it is necessary to provide an experimental spray carbonization device with simple equipment, easy operation, small amount of raw material usage and large gas-liquid contact area. Utility Model Content

[0006] The purpose of the utility model is to solve the above technical problems and provide a small-scale spray carbonization device for experiments.

[0007] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0008] The utility model provides a small-scale spray carbonization device for experiments, comprising a carbonization tower, a pressure barrel, a gas mixer, a carbon dioxide storage tank and an air compressor.

[0009] Specifically, the gas mixer can evenly mix carbon dioxide and air in different proportions to provide a stable gas source for carbonization. The atomizing nozzle can quickly turn the reaction liquid into a mist and react with carbon dioxide, which is highly practical.

[0010] In one embodiment, the carbonization tower includes a cylindrical structure at an upper end and a conical structure at a lower end.

[0013] In one embodiment, a gas distributor is installed near the bottom of the carbonization tower, the carbonization gas inlet is located on the side of the cone structure at the bottom of the carbonization tower, and the gas distributor is located above the carbonization gas inlet.

[0014] Specifically, a gas distributor is installed near the bottom of the carbonization tower to evenly disperse the carbon dioxide mixed gas entering the tower.

[0015] In one embodiment, the atomizing nozzle is a single-fluid pressure type structure, and is fixedly installed in a mounting hole at the center of the top of the carbonization tower.

[0016] Specifically, the atomizing nozzle is a single-fluid pressure type structure, rather than a centrifugal or two-fluid type nozzle.

[0017] This solution combines the characteristics of traditional spray carbonization, adopts a single-fluid pressure-type atomizing nozzle for atomization, and uses a pneumatic pressure barrel to provide spray pressure, avoiding the need for a large-diameter carbonization tower for centrifugal nozzles, and realizing equipment miniaturization. At the same time, it avoids the problem of two-fluid nozzles seriously affecting carbonization efficiency due to mixing a large amount of gas.

[0018] In one embodiment, the air compressor includes an air compressor housing, a first air compressor air outlet and a second air compressor air outlet disposed on the air compressor housing.

[0019] Specifically, an air compressor is a small gas compressor used to provide pressure to a pressure tank and air to a gas mixer.

[0020] In one embodiment, the pressure barrel is a pneumatic pressure barrel, which includes a barrel body and a barrel cover, on which a pressure barrel air inlet, a pressure barrel discharge port, an air regulator, a safety valve and a gas release valve are provided, and liquid to be carbonized is placed in the barrel body;

[0021] The air inlet of the pressure barrel is connected to the air outlet of the second air compressor through a pipeline, and the pipeline is provided with a second compressed air flow meter and a second compressed air valve;

[0022] The discharge port of the pressure barrel is connected with the atomizing nozzle through a feed pipeline, and a discharge valve is arranged on the feed pipeline.

[0023] Specifically, the pressure barrel mainly provides spray pressure for the raw materials, and the air inlet of the pressure barrel is connected to the air compressor. The second air compressor outlet of the air compressor is connected to the air inlet of the pressure barrel to provide air pressure for the pressure barrel, thereby driving the reaction liquid inside the pressure barrel to enter the atomizing nozzle through the feed pipeline for atomization.

[0024] In one embodiment, the gas mixer includes a tank body, an air inlet A and an air inlet B disposed on one side of the tank body, and an air outlet C disposed on the other side of the tank body;

[0025] The air inlet A is connected to the air outlet of the carbon dioxide storage tank through a pipeline equipped with a carbon dioxide flowmeter;

[0026] The air inlet B is connected to the air outlet of the first air compressor through a pipeline equipped with a first compressed air flow meter and a first compressed air valve;

[0027] The gas outlet C is connected to the carbonization gas inlet through a pipeline equipped with a mixed gas flow meter and a mixed gas valve.

[0028] Specifically, the gas mixer is used to produce a carbon dioxide mixed gas, and contains two air inlets (air inlet A and air inlet B) and one air outlet (air outlet C). One of the air inlets is connected to the carbon dioxide storage tank, and the other air inlet is connected to the air outlet of the first air compressor. The air outlet is connected to the carbonization air inlet at the bottom of the carbonization tower.

[0029] In one embodiment, the carbon dioxide storage tank is a carbon dioxide cylinder.

[0030] Working principle: When using the experimental small spray carbonization device provided by the utility model, first, turn on the air compressor and the carbon dioxide cylinder, and the carbon dioxide gas and compressed air enter the gas mixer at the same time to be evenly mixed in a certain proportion, and then injected into the carbonization tower through the outlet gas flow meter. At the same time, open the second compressed air valve of the pressure barrel, and use the second compressed air flow meter to adjust the compressed air flow. The compressed air enters the pressure barrel through the air inlet, drives the reaction liquid in the pressure barrel to be injected into the atomizing nozzle at the top of the carbonization tower. Due to the effect of the liquid pressure, the atomizing nozzle is prompted to atomize and spray the reaction liquid. At this time, the carbon dioxide fully contacts the mist reaction liquid to cause a carbonization reaction, and finally the carbonization product is discharged through the discharge port. It is very practical. This is the working process of this small spray carbonization device.

[0031] The beneficial effects of the utility model are as follows:

[0032] 1. The utility model combines the characteristics of traditional spray carbonization, adopts a single-fluid pressure nozzle for atomization, and uses a pneumatic pressure barrel to provide spray pressure, avoiding the need for a large-diameter carbonization tower for centrifugal nozzles, and realizing equipment miniaturization. At the same time, it avoids the problem that the two-fluid nozzle seriously affects the carbonization efficiency due to the mixing of a large amount of gas.

[0033] 2. The utility model adopts a single-fluid pressure nozzle for atomization and a pneumatic pressure barrel to provide spray pressure. The operation is simple and the outflow of raw materials can be controlled by adjusting the spray pressure and replacing the nozzle, so that the amount of raw materials used is small.
