Description
Technical field:
the present invention relates to CO 2 Gas generator, in particular CO for aquatic weed aquarium 2 A gas generator.
The background technology is as follows:
at present, CO in aquatic weed fish tank on the market 2 Manually supplemented CO 2 The gas generating devices are mainly two types. Or the reaction is full reaction type, that is, reactants react completely after being fed to generate all CO 2 The pressure of the gas in the reaction vessel is up to more than 1.6Mpa, and the household use is unsafe. Or the output pressure is unstable in the gas production process because of the lack of effective control of the gas production in the effective CO2 gas preparation process.
The invention comprises the following steps:
the invention aims to overcome the defects of the prior art and provide the CO for the household aquatic weed fish tank 2 The supplementing device.
The technical scheme of the invention is as follows:
CO for aquatic weed fish tank 2 The gas generator comprises at least two closed spaces, a pressure sensor, at least two one-way valves, a control module and an electromagnetic valve;
the sealed spaces are respectively filled with carbon dioxide reactant, wherein the carbon dioxide reactant in at least one sealed space is stored in the form of aqueous solution, which is called one sealed space, and the other sealed space is filled with the rest CO 2 Reactants, called a class II closed space;
the first type of closed space is communicated with the second type of closed space through a first pipeline and a first one-way valve; the second type of closed space is communicated with the first type of closed space through a second pipeline and a second one-way valve; the first one-way valve and the second one-way valve are opposite in direction;
the first type of closed space is connected with the second type of closed space through a third pipeline through an electromagnetic valve, one end of the third pipeline is deep in the bottom of the first type of closed space, and the electromagnetic valve is connected with the control module;
the detection end of the pressure sensor is connected with one type of closed space or two types of closed spaces, and the signal end of the pressure sensor is connected with the control module.
Further, the at least two closed spaces may be placed in different containers or in closed and isolated spaces of the same container.
The two kinds of closed spaces are communicated with each other through pipelines. The sealed spaces are communicated with each other through pipelines.
Further, the first check valve opening pressure is higher than the second check valve opening pressure. The first one-way valve has higher opening pressure so as to ensure that the gas in the first high-pressure closed space flows in one direction in the second low-pressure closed space on the premise of ensuring that the first closed space has higher forward pressure difference relative to the second closed space. The second one-way valve has lower opening pressure, so that the gas in the second-class high-pressure airtight space flows in one direction into the first-class low-pressure airtight space.
Preferably, the second type of closed space is connected with a pressure sensor; the control module opens or closes an electromagnetic valve where a communication pipeline is positioned between the first type of closed space and the second type of closed space according to the numerical value of the pressure sensor. The control module can control the opening or closing of the electromagnetic valve so as to realize the communication or closing of the channel.
The pressure difference between the two kinds of reactants can promote the reactants in the form of aqueous solution in one kind of closed space to enter the second kind of closed space where the other kind of reactants are located through the opened electromagnetic valve, thereby achieving the purpose of preparing CO2 gas in the second kind of closed space.
The gas-using switch is connected with the outside of the second-class closed space reaction container and can be a manual switch or an electromagnetic valve switch.
The control module can control the opening of the electromagnetic valve at the gas end in a time timer mode so as to achieve the purpose of automatically using gas.
The safety valve is arranged outside the reaction vessel and used as a pressure relief device for ensuring the safety when the pressure of the reaction vessel exceeds a warning line under special conditions.
One type of enclosure houses a reactant in the form of a solution.
Wherein the second type of closed space is used as a place for chemical reaction, and all reactants except the reactants in the first type of closed space are stored. The outer part of the second type closed space is connected with the gas using end. Along with the use of the gas using end, the gas pressure in the second-class closed space reaction container is reduced, and the pressure in the first-class closed space is larger than the gas pressure in the second-class closed space reaction container. When the pressure difference reaches the working opening pressure of the first one-way valve, gas flows from the first closed space to the second closed space through the first one-way valve.
With the further use of the end-of-use gas, when the pressure in the second closed space reaction vessel reaches a set pressure, the control module opens the solenoid valve liquid path channel connecting the first closed space and the second closed space. Because of the relation of the opening pressure of the first one-way valve, the pressure in the first closed space for containing the solution reactant is larger than the pressure in the second closed space, the solution reactant enters the second closed space through the electromagnetic valve liquid path channel under the pressure, and the two reactants can generate CO after being mixed in the second closed space 2 And (3) gas. As more and more gas is generated, the pressure in the second closed container is gradually increased, and when the pressure in the second closed space is increased to a set pressure, the control module closes the solenoid valve liquid path channel connecting the first closed space and the second closed space.
The external gas end of the second airtight space is provided with a pressure reducing valve so as to meet the stable gas requirement of the gas end.
The control module is integrated with the wireless communication module or connected with the wireless communication module, and can realize the access of the mobile terminal and the setting of the time timer of the intelligent module through the access of the mobile terminal equipment.
The time timer of the control module can control the opening and closing of the air end electromagnetic valve and the relay connected with the control module, so that the purpose that the intelligent module time timer manages electric equipment connected with the relay outside can be achieved. When the external electric equipment is a lighting system, CO2 and illumination can be synchronously supplemented so as to facilitate photosynthesis of aquatic plants in the aquarium.
Compared with the prior art, the invention has the beneficial effects that:
(1) The invention can be applied to CO of aquatic plants in a household aquarium 2 Is provided. Illumination and CO required by synchronous management of aquatic plants in fish tank 2 Meets the daily photosynthesis requirement of aquatic weeds.
(2) The invention controls the amount of solution state reactant participating in chemical reaction by pressure during use, precisely controls the upper limit of the pressure in the reaction vessel at a lower level, and is safer for household life.
(3) In the invention, the two kinds of reaction containers are communicated with the one kind of solution state reactant containers by adopting the one-way valve, so that the one kind of solution state reactant containers can also be used as storage containers for generating gas.
(4) In the invention, the one-way valve is also adopted to communicate the one-class solution-state reactant container with the two-class reaction container, and after the electromagnetic valve between the one-class solution-state reactant container and the two-class reaction container is communicated, the one-class solution-state reactant can automatically enter the two-class reaction container under the action of pressure, thereby avoiding the need of pumping the liquid-state reactant into the reaction container by using a liquid pump.

Detailed Description
The present invention will be described in further detail with reference to examples and drawings, but the scope of the present invention should not be limited thereto.
Example 1: the reactants in this example are citric acid solution 4 and baking soda powder 3. Which chemically reacts to form CO 2 The chemical reaction equation of the gas is:
3NaHCO 3 +C 6 H 8 O 7 ＝C 6 H 5 O 7 Na 3 +3H 2 O+3CO 2 ↑
CO as shown in FIG. 1 2 The gas generator consists of a first container 1 and a second container 2, wherein the container 1 contains 200g of citric acid solution of citric acid and 250ml of water, and the container 2 contains 200g of baking soda powder.
Step 1, manually adding a certain amount of materials into a container 1Baking soda as CO 2 The starting conditions of the generator. In the initial state, the a solenoid valve 8 is in the closed state.
When sodium bicarbonate put into the container 1 reacts with citric acid, the pressure in the container 1 is gradually increased, and CO in the container 1 2 Gas will enter the second type container 2 through the non-return valve 6, and at the same time the pressure in the first type container 1 will also maintain a larger positive pressure against the second type container 2 due to the presence of the non-return valve 6. When the pressure is insufficient to open the non-return valve 6, the pressure in the second type of container 2 will also maintain a positive pressure against the first type of container 1 due to the presence of the non-return valve 6.
Step 2 will enter CO 2 And (5) automatically generating. The control module 10 reads the data of the pressure sensor 5, detects that the pressure in the two kinds of containers 2 is lower than a certain value, the control module 10 opens the electromagnetic valve 8, and the citric acid solution 4 in the container 1 enters the container 2 through the electromagnetic valve 8 due to the fact that the container 1 has a positive pressure difference relative to the container 2, and the citric acid solution 4 entering the container 2 generates a severe chemical reaction with the baking soda reactant 3 in the container 2 to generate a large amount of CO 2 Gas, pressure in container 2 with large amount of CO 2 When the pressure is higher than the pressure in the container 1, the citric acid reactant 4 will not enter the container 2 any more, and the gas in the container 2 will flow into the container 1 through the electromagnetic valve 8 and the one-way valve 7 for the purpose of gas storage, and at the same time the pressure in the container 1 and the container 2 are gradually raised synchronously.
When the pressure sensor 5 detects that the pressure in the container 2 is greater than a certain set value, the control module closes the solenoid valve 8.
As the citric acid reactant 4 in the vessel 2 is depleted, the pressure in the vessel 2 will be maximized.
Step 3 will enter the gas use phase: the electromagnetic valve 9 can be opened at regular time according to a timer in the control module so as to achieve the purpose of automatic gas utilization. With the electromagnetic valve 9 at the gas using end B being opened, the pressure in the container 2 gradually decreases, when the pressure in the container 1 is larger than the pressure of the container 2 and the working opening pressure of the one-way valve 6, the one-way valve 6 is opened, and CO in the container 1 2 The gas will enter the container 2 to replenish the CO2 gas in the container 2.
At this time, the pressure in the container 1 will always maintain a large positive pressure difference relative to the container 2 due to the presence of the one-way valve 6.
With the gas consumer B solenoid valve 9 open, the embodiment of fig. 1 will repeat the process of step 2 for CO2 gas production.
This is repeated until the citric acid solution 4 in the container 1 is exhausted, and the process of generating and using CO2 gas is completed.
Example 2: the reactants in this example are citric acid solution 4 and baking soda powder 3. Which chemically reacts to form CO 2 The chemical reaction equation of the gas is:
3NaHCO 3 +C 6 H 8 O 7 ＝C 6 H 5 O 7 Na 3 +3H 2 O+3CO 2 ↑
CO as shown in FIG. 2 2 The gas generator is composed of a container 1, a container 2 and a container 22, wherein the container 1 contains 400g of citric acid solution of citric acid and 500ml of water, and the container 2 and the container 22 respectively contain 200g of baking soda powder.
Step 1, artificially adding a certain amount of baking soda as CO into a container 1 2 The starting conditions of the generator. In the initial state, the a solenoid valve 8 is in the closed state.
When sodium bicarbonate put into the container 1 reacts with the citric acid 4, the pressure in the container 1 is gradually increased, and CO in the container 1 2 The gas will enter the second type container 2 through the one-way valve 6; because the second-type container 2 is in gas-path communication with the second-type container 22, the second-type container 2 and the second-type container 22 are pressure-converged. At the same time, the pressure in the container 1 of one type will also maintain a greater positive pressure relative to the container 2 of the second type and the container 22 of the second type due to the presence of the non-return valve 6. When the pressure is insufficient to open the non-return valve 6, the pressure in the first type of container 1 relative to the second type of container 2 and the second type of container 22 will also maintain a positive pressure due to the presence of the non-return valve 6.
Step 2 will enter CO 2 Automatic generation: control ofThe module 10 reads the pressure data of the pressure sensor 5, detects that the pressure in the second container 2 is lower than a certain value, the control module 10 opens the electromagnetic valve 8, and as the first container 1 has a positive pressure difference relative to the second container 2 and the second container 22, the citric acid solution 4 in the first container 1 enters the second container 2 and the second container 22 through the electromagnetic valve 8, and the citric acid solution 4 entering the second container 2 and the second container 22 generates a severe chemical reaction with the baking soda reactant 3 in the second container 2 and the second container 22 to generate a large amount of CO 2 A gas; the pressures in the two kinds of containers 2 and 22 gradually rise along with the generation of a large amount of CO2 gas, when the pressure is higher than the pressure in the container 1, the citric acid reactant 4 in the one kind of containers does not enter the two kinds of containers 2 and 22 any more, and meanwhile, the gas in the two kinds of containers 2 and 22 flows into the container 1 through the electromagnetic valve 8 and the one-way valve 7 to achieve the purpose of gas storage, and meanwhile, the pressures in the one kind of containers 1, the two kinds of containers 2 and 22 gradually rise synchronously.
When the pressure in the container 2 detected by the pressure sensor 5 is greater than a certain set value, the control module closes the solenoid valve 8.
As the citric acid reactant 4 in the two-type containers 2, 22 is depleted, the pressure in the two-type containers 2, 22 will be maximized.
Step 3 will enter the gas use phase: the electromagnetic valve 9 can be opened at regular time according to a timer in the control module so as to achieve the purpose of automatic gas utilization. Along with the opening of the electromagnetic valve 9 at the gas using end B, the pressure in the second-class container 2 is gradually reduced, when the pressure in the first-class container 1 is larger than the pressure of the second-class container 2 and the working opening pressure of the one-way valve 6, the one-way valve 6 is opened, and CO2 gas in the first-class container 1 enters the second-class container 2 to supplement the CO2 gas in the second-class container 2. The pressures in the two-type container 2 and the two-type container 22 converge due to the gas path communication between the two-type container 2 and the upper part of the two-type container 22.
At this time, due to the existence of the check valve 6, the pressure in the first-class container 1 always maintains a larger positive pressure difference relative to the second-class containers 2 and 22.
With the gas consumer B solenoid valve 9 open, the embodiment of fig. 2 will repeat the process of step 2 for CO2 gas production.
This is repeated until the citric acid solution 4 in the container 1 is exhausted, and the process of generating and using CO2 gas is completed.
The gas generator of the invention adopts an effective pressure detection device to control the amount of reactants participating in chemical reaction each time in the reaction vessel so as to achieve the purpose of preparing CO2 gas at any time. The working pressure of the gas generator can be set in a lower and safer area, so that the gas generator can be applied to daily living residence.
