Description

Technical Field

[0001] This utility model relates to a quantitative test chamber, and more particularly to a quantitative test chamber for carbonization reaction. Background Technology

[0002] Carbon capture and storage (CCS) technology refers to the process of separating carbon dioxide produced by industry and related energy sectors through carbon capture technology, and then storing it in locations isolated from the atmosphere, such as the seabed or underground, using carbon storage methods. It is divided into chemical sequestration, mineral sequestration, and geological sequestration. Mineral sequestration mainly refers to using minerals that can react with CO2 to form stable carbonate materials, thereby sequestering the carbon dioxide. Natural carbonization at room temperature and pressure takes a long time; therefore, research primarily employs accelerated carbonization methods, increasing the carbon dioxide concentration to speed up the carbonization reaction process.

[0003] Currently, commonly used ordinary carbonization boxes or carbonization reactors only provide the conditions for carbonization reaction and cannot quantify the amount of carbon dioxide reacted during the reaction process. Therefore, current research usually measures the amount of carbonization by calcining samples at the beginning and end of the carbonization reaction, but cannot quantify the carbonization reaction by controlling and measuring the reaction process. Summary of the Invention

[0004] Purpose of the invention: The purpose of this utility model is to provide a quantitative test chamber for carbonization reaction that quantitatively measures the carbon dioxide consumed in the reaction by weighing and gas methods.

[0005] Technical solution: This utility model discloses a quantitative test chamber for carbonization reaction. The quantitative test chamber for carbonization reaction includes a reaction chamber, a flow meter installed on the air inlet of the reaction chamber, a temperature and humidity controller installed on the outer wall of the reaction chamber, a humidifier, a heating device, a cooling device and a weighing sensor installed inside the reaction chamber, and a dehumidifier and a carbon dioxide gas controller connected to the reaction chamber.

[0006] The reaction chamber is made of acrylic or steel. Acrylic chambers allow direct observation of the reaction inside from the outside, while steel chambers are suitable for high-pressure carbonization reactions. The cover plate on top of the chamber is connected to the chamber with bolts or quick-release clips. Several gas and circuit interfaces are provided around the reaction chamber for connecting various sensors and controllers to the chamber.

[0007] The inlet flow meter is a dedicated carbon dioxide flow meter installed at the only inlet of the housing, used to measure the amount of carbon dioxide gas entering the housing.

[0008] The temperature and humidity controller is connected to a monitoring probe inside the reaction chamber and is used to control the operation of other temperature and humidity devices according to settings.

[0009] The humidifier is an ultrasonic humidifier with a fan.

[0010] The dehumidifier includes a gas circulation pump and a gas dryer connected to the reaction chamber.

[0011] The heating device includes an electric heater and a fan.

[0012] The refrigeration device is a semiconductor refrigeration device or a compressor refrigeration device.

[0013] The weighing sensor is located at the bottom of the reaction chamber.

[0014] The carbon dioxide concentration inside the reaction chamber is monitored and controlled by a carbon dioxide gas controller, which includes a carbon dioxide concentration sensor, an integrated gas pipeline switch, a vacuum pump 12, a pressure protection device, and a radiator.

[0015] The integrated gas pipeline switch consists of a carbon dioxide inlet control valve and a gas replacement pipeline control valve. A carbon dioxide concentration sensor is connected to the reaction chamber and the integrated gas pipeline switch to control carbon dioxide inlet and gas replacement. A vacuum pump for accelerating gas replacement and a pressure protection device to prevent overpressure are connected to the reaction chamber and the atmosphere. The aforementioned carbon dioxide gas controller can automatically control the entry of carbon dioxide gas according to the set concentration. For experiments conducted with low-concentration carbon dioxide, the set concentration can be achieved by replacing the gas with external gas. For experiments conducted with high-concentration carbon dioxide, the set concentration can be quickly achieved by pre-evacuating the chamber and then introducing carbon dioxide. The pressure protection device can monitor the pressure inside the chamber in real time and release pressure promptly when it becomes too high.

[0016] The inlet flow meter, temperature and humidity controller, and weighing sensor carbon dioxide gas controller are equipped with communication interfaces for operation monitoring, data acquisition, and function control. The communication interfaces are connected to the local area network to realize equipment operation monitoring, test data acquisition, and equipment function control.

[0017] This utility model's quantitative carbonization reaction test chamber achieves precise quantitative analysis of the carbonization reaction by integrating weighing and gas monitoring methods. A weighing sensor monitors real-time changes in sample mass, and combined with concentration monitoring data from a carbon dioxide gas controller and gas flow data from a flow meter, carbon dioxide consumption is calculated simultaneously, forming a dual composite verification mechanism. A temperature and humidity controller links a humidifier, heating / cooling device, and dehumidifier to create a constant carbonization reaction environment; an integrated switch and vacuum pump in the gas pipeline enable dynamic gas replacement within the chamber, ensuring a controllable concentration gradient. A communication interface centrally collects weighing, temperature, humidity, air intake, and gas concentration data, which can be fused using algorithms to output quantitative results.

[0018] Beneficial effects: Compared with the prior art, the present invention has the following significant advantages: The carbonization reaction quantitative test chamber of the present invention adopts a modular design, and the structure of each system is simple and easy to maintain. By setting temperature, humidity and carbon dioxide concentration monitoring and control devices, the carbon dioxide consumption during the carbonization reaction process can be quantitatively monitored by weighing method and gas method. It can meet the requirements of different experiments on reaction conditions. Furthermore, the operation of the test process can be monitored through the communication interface of each device in the test chamber, which can ensure the stability of the test conditions.

Detailed Implementation

[0023] The technical solution of this utility model will be further described below with reference to the embodiments. The test materials used in the embodiments can all be purchased through conventional means.

[0024] Example 1

[0025] like Figure 1 and Figure 2 As shown, the carbonization reaction quantitative test chamber of this utility model includes a reaction chamber 1, a flow meter 2, a temperature and humidity controller 3, a humidifier 4, a dehumidifier 5, a heating device 6, a cooling device 7, a weighing sensor 8, and a carbon dioxide gas controller 9.

[0026] The reaction chamber 1 is made of transparent acrylic sheet, and the top cover is connected to the chamber with quick-release buckles. The entire chamber can withstand a pressure of up to 2MPa.

[0027] The flow meter 2 is located at the air inlet of the reaction chamber 1 and is installed between the carbon dioxide cylinder and the reaction chamber 1. It uses thermal mass flow measurement and does not require temperature and pressure compensation. The output includes a built-in display screen and an RS485 communication interface.

[0028] On the outside of the reaction chamber 1, a temperature and humidity controller 3 is installed. It has a built-in temperature and humidity probe to monitor the ambient temperature and humidity inside the chamber. It can control the temperature control equipment and humidity control equipment according to the settings. The operation methods include the built-in screen and RS485 communication.

[0029] Humidifier 4 is an ultrasonic humidifier installed inside the reaction chamber 1, with a small fan on top to improve humidification efficiency. Dehumidifier 5 consists of a gas circulation pump and a silica gel drying tube, connected to the chamber via an inlet and outlet pipe. Heating device 6 consists of an electric heating element and a fan, and cooling device 7 consists of a semiconductor cooling chip, an external heat sink, and an internal fan.

[0030] Weighing sensor 8 is installed inside reaction chamber 1 to monitor changes in sample mass during the reaction process. The sensor reads the value via an RS485 communication interface.

[0031] like Figure 3 As shown, the carbon dioxide concentration inside the reaction chamber 1 is monitored and controlled by a carbon dioxide gas controller 9. The carbon dioxide gas controller 9 includes a carbon dioxide concentration sensor 10, a gas pipeline integrated switch 11, a vacuum pump 12, a pressure protection device 13, and a radiator 14. The gas pipeline integrated switch 11 consists of a carbon dioxide inlet control valve and a gas replacement pipeline control valve, and is connected to the reaction chamber 1 via a flow meter 2. The carbon dioxide concentration sensor 10 is connected to the reaction chamber 1 to detect the gas concentration inside the reaction chamber 1 and is connected to the gas pipeline integrated switch 11 to control the carbon dioxide inlet and gas replacement. The vacuum pump 12, used to accelerate gas replacement, and the pressure protection device 13, used to prevent overpressure, both have independent switches and gas lines connected to the reaction chamber 1 and the atmosphere, and can be automatically or manually activated according to settings. The radiator 14 is a fan.

[0032] The carbon dioxide gas controller 9 samples a small amount of gas from the test chamber and detects the carbon dioxide concentration using an infrared carbon dioxide concentration sensor. When the concentration does not reach the set concentration, the controller will simultaneously open the carbon dioxide inlet valve and the gas replacement valve.

[0033] The operating steps for the carbonization reaction quantitative test chamber are as follows:

[0034] (1) Turn on the temperature and humidity controller, set the required temperature and humidity inside the chamber, and after the temperature and humidity inside the chamber reach the set value, open the top cover of the chamber and place the sample to be tested on the weighing sensor inside the chamber.

[0035] (2) Turn on the carbon dioxide gas controller and set the required carbon dioxide concentration in the chamber. For low concentrations below 50%, gas replacement can be used to achieve the desired concentration. For high concentrations, a vacuum pump is required to remove the air from the chamber before introducing carbon dioxide.

[0036] (3) After the carbon dioxide concentration in the chamber reaches the set value, manually close the gas replacement valve and start collecting data during the test on the host computer. After the test is completed, take out the sample and close the test chamber in time. The carbon dioxide content reacted during the test is the flow rate displayed by the inlet flow meter. For solid samples that directly absorb carbon dioxide, the reaction amount can also be determined by the increase in sample mass.

[0037] Therefore, the carbonization reaction quantitative test chamber of the present invention solves the problem of the inability to quantitatively determine the carbon dioxide consumption in the carbonization reaction in the prior art. This test chamber is used to measure the gas-solid reaction between a solid and carbon dioxide gas. Through weighing and gas methods, the consumption of carbon dioxide can be quantitatively monitored, meeting the needs of different test conditions. The test chamber is modularly designed, has a simple structure, is easy to maintain, and has a communication interface for equipment monitoring and data acquisition, ensuring the stability of test conditions.
