Description

Technical Field

[0001] This utility model relates to a carbon monoxide production apparatus, specifically, to an apparatus for producing calcium formate from carbon monoxide. Background Technology

[0002] In the industrial production of calcium formate from carbon monoxide, the reactor, as a core piece of equipment, plays a crucial role in the gas-liquid reaction. Traditional reactor designs suffer from numerous technical problems in actual production, severely impacting production efficiency and product quality. The liquid flow within traditional reactors is suboptimal, lacking an effective swirling mechanism, leading to uneven distribution of reactants. This static or inefficient mixing state limits the contact area between carbon monoxide and the reaction liquid, resulting in low gas-liquid mass transfer efficiency, directly affecting reaction rate and conversion rate. During prolonged reactions, crystallized products and impurities easily settle to the bottom of the reactor under gravity, forming deposits and blockages near the discharge port, affecting continuous product output. Furthermore, existing equipment results in insufficient mixing, further reducing overall reaction efficiency.

[0003] Therefore, there is an urgent need for a device for producing calcium formate from carbon monoxide, which can ensure product quality and production efficiency by allowing materials to react more uniformly. It should have a simple and reliable structure, be easy to operate, have low maintenance costs, and be widely applicable. Utility Model Content

[0017] To make the technical solution of this utility model easier to understand, the technical solution of this utility model will now be clearly and completely described in conjunction with the accompanying drawings and specific embodiments.

[0018] Example 1: like Figure 1-6 As shown, an apparatus for producing calcium formate from carbon monoxide according to this embodiment includes several reaction vessels 1 and a gas inlet distributor 2 disposed within the reaction vessels 1, wherein: A power mechanism 3 is provided at the center of the top of several of the reactors 1. The power output end of the bottom of the power mechanism 3 is connected to the stirring rod 4. One end of the stirring rod 4 passes through the reactor 1 and is connected to the power mechanism 3, and the other end of the stirring rod 4 is movably connected to the bottom of the reactor 1. The top side of the reactor 1 is provided with a carbon monoxide inlet 5. The carbon monoxide inlet 5 is located inside the reactor 1. The carbon monoxide inlet 5 is connected to the gas flow communication pipe 6. The other end of the gas flow communication pipe 6 is connected to the gas inlet distributor 201 on the gas inlet distributor 2. The gas inlet distributor 2 includes an air inlet pipe 201, one end of which is connected to a connecting pipe 202. The connecting pipe 202 has a protrusion 206 inside. One end of the connecting pipe 202 with the protrusion 206 is movably fitted with one end of a rotating ring 203. The rotating ring 203 has a groove 207 corresponding to the protrusion 206. The outer ring of the rotating ring 203 is alternately provided with a plurality of first-type airflow driven pipes 204 and second-type airflow driven pipes 205. The plurality of first-type airflow driven pipes 204 and second-type airflow driven pipes 205 are alternately arranged. The ports of a plurality of first-type airflow driven pipes 204 and second-type airflow driven pipes 205 away from the rotating ring 203 are sealed. One side of the plurality of first-type airflow driven pipes 204 is a first side region 204-1 and the other side is a second side region 204-2. One side of the plurality of second-type airflow driven pipes 205 is a third side region 205-1 and the other side is a fourth side region 205-2. A plurality of airflow holes 208 are provided in the first side region 204-1 and the third side region 205-1. The second side region 204-2 and the fourth side region 205-2 are non-perforated regions. The reactor 1 is provided with several feed inlets 7 at the top and a discharge outlet 8 at the bottom.

[0019] The connecting pipe 202 has a ring structure, and the rotating ring 203 connected to it also has a ring structure. Both the connecting pipe 202 and the rotating ring 203 have hollow interiors, forming an airflow channel. The connecting pipe 202 and the rotating ring 203 are interconnected. The interior of the rotating ring 203 is interconnected with the interiors of several first-type airflow driven pipes 204 and second-type airflow driven pipes 205, forming an airflow channel. The stirring rod 4 passes through the center of the rotating ring 203 in sequence and is movably connected to the bottom of the reactor 1.

[0020] Example 2: Unlike Example 1, such as Figure 1-6As shown in the figure, in this embodiment, an apparatus for producing calcium formate from carbon monoxide is provided with a plurality of stirring blades 14 on the stirring rod 4.

[0021] The reactors 1 are connected by production pipelines, and a discharge pipe is provided at the discharge port 8 at the bottom of the reactors 1, and a power pump is provided on the discharge pipe.

[0022] The angle between a number of first-type airflow driven pipes 204 and second-type airflow driven pipes 205 is 45° and they are alternately arranged.

[0023] The top of the reactor 1 is equipped with a set of external tracing pipe inlets and outlets 9.

[0024] A set of sight glasses 10 is provided on the top of the reactor 1.

[0025] A pressure measuring port 11 is provided on one side of the top of the reactor 1.

[0026] The thermometer port 12 and the level gauge port 13 are located on one side of the top of the reactor 1.

[0027] When the device is in use, the gas enters the gas flow communication pipe 6 from the carbon monoxide inlet, then enters the inlet pipe 201, then the connecting pipe 202, and through the rotating ring 203, the gas flow enters the first type of gas flow drive pipe 204 and the second type of gas flow drive pipe 205. The gas flow holes 208 on the first type of gas flow drive pipe 204 and the second type of gas flow drive pipe 205 exhaust gas, driving the rotating ring 203 to rotate and form a vortex.

[0028] In one embodiment, gas, liquid, and solid coexist in the reactor 1, with solid matter occupying the lowest proportion. The solid matter settles at the bottom of the reactor 1, below the position set by the gas inlet distributor 2. The gas inlet distributor 2 allows carbon monoxide gas to enter the liquid-filled reactor 1 uniformly in the form of small bubbles. At the same time, the airflow holes 208 on the first type of airflow drive pipe 204 and the second type of airflow drive pipe 205 have the same opening direction. When the device starts running, the airflow holes 208 will continuously spray gas. After the 3 MPa gas enters the reactor 1, it is simultaneously sprayed in one direction, stirring the liquid in the reactor 1 in the same direction. At the same time, the stirring rod 4 is equipped with several stirring blades 14, which stir in the same direction, increasing the contact area between the carbon monoxide gas and the calcium hydroxide liquid, making the gas-liquid reaction more complete.

[0029] In actual production, such as Figure 6The three reactors shown are connected in series. After being pressurized to 3 MPa by a carbon monoxide compressor, carbon monoxide gas enters the first reactor 1. After the liquid inside the first reactor has fully reacted, it enters the second reactor 1 through a pipe from the top of the first reactor 1. After the liquid inside the second reactor 1 has fully reacted, it enters the third reactor 1 through a pipe from the top of the second reactor 1 and reacts with the liquid inside the third reactor 1.

[0030] Liquid calcium hydroxide enters the third reactor from the top, reacting fully with carbon monoxide to produce a low-concentration calcium formate liquid mixture. From the bottom of the third reactor, it enters the top of the second reactor, reacting fully with carbon monoxide to produce a medium-concentration calcium formate mixture. From the bottom of the second reactor, it enters the top of the first reactor, reacting fully with carbon monoxide to produce a high-concentration calcium formate product liquid. The high-concentration calcium formate product liquid is then forced out from the bottom of the reactor and enters a second- or third-stage heat exchanger to exchange heat with the calcium hydroxide solution entering the third reactor. This lowers the product solution temperature while raising the temperature of the calcium hydroxide solution entering the reactor. The calcium formate reaction temperature is 200 to 220 degrees Celsius, requiring external heat energy (electric heating or steam heating). Increasing the heat exchanger's effective heat recovery helps save energy and reduce consumption.

[0031] After heat exchange between the calcium formate product solution and the calcium hydroxide solution, the solution then enters a heat exchanger to exchange heat with the water entering the system. The water is heated and then digests with calcium carbonate or calcium oxide. The cooled calcium formate product solution enters a centrifuge for separation. This further recovers heat, saving energy and reducing consumption.

[0032] In a continuous series production process, by controlling the inflow rate of the third reactor (Reactor 1) to ensure that the inflow rate of the third reactor (Reactor 1) matches the inflow rate of the second reactor (Reactor 1), the liquid level in the third reactor (Reactor 1) can be maintained. Similarly, the same applies to the second and first reactors (Reactor 1). This allows for continuous feeding, continuous product output, and series production.

[0033] 3 to 20 reactors can be connected in series in production. The above example uses three reactors, but in actual production, two or four reactors can also be connected in series. The number of reactors in series can be adjusted according to the actual operating conditions. The advantage of series production is that it avoids the frequent switching operations of single-reactor reactions. Switching reactor 1 requires purging residual carbon monoxide gas, and adding new material to reactor 1 also requires purging the air inside with nitrogen, which is labor-intensive and time-consuming. There are also safety hazards. Series production solves this production problem, allowing calcium formate production to run continuously, avoiding the safety risks during the switching process of single reactor 1, and increasing production efficiency.

These embodiments are merely illustrative and are intended only to provide a more intuitive and clear way of understanding the content of this utility model, not to limit the technical solutions described herein.
