[0002] When conducting a calorimetric experiment of a chemical reaction with exhaust gas generation (i.e., an experiment to measure the heat of reaction of a chemical reaction), since the exhaust gas will take away some heat, resulting in a certain deviation in the measured heat of reaction of the chemical reaction, it is necessary to collect and record the content of the exhaust gas, calculate the heat taken away by the exhaust gas based on the content of the exhaust gas, and thus correct the measured heat of reaction of the chemical reaction, and then accurately measure the heat of reaction of the chemical reaction. However, the prior art simply absorbs the exhaust gas through traditional chemical experimental devices, and does not measure the content of the exhaust gas. Therefore, it is necessary to provide a device that can collect and record the content of the exhaust gas. Utility Model Content

The top of the air inlet tank and the air outlet tank are both equipped with a monitoring balance capable of measuring mass. A plurality of absorption components are provided. The absorption components are connected end to end with each other and then connected with the air inlet tank and the air outlet tank.

[0006] The experimental exhaust gas is introduced into the air inlet tank through the exhaust inlet, and then discharged through the three-way discharge piece. The absorption component includes a data processing seat, an absorption tank, an anti-backflow piece and a branch discharge pipe.

[0020] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Reference Figure 1 and 2 A device for collecting and recording exhaust gas changes includes an air inlet tank 1, an absorption component 2 and an air outlet tank 3. The bottom ends of the air inlet tank 1 and the air outlet tank 3 are both equipped with a monitoring balance 4 capable of measuring mass. There are multiple absorption components 2, and each absorption component 2 is connected to each other end to end and then connected to the air inlet tank 1 and the air outlet tank 3.

[0022] The experimental exhaust gas is introduced into the air intake tank 1 through the exhaust inlet 11, and then the exhaust gas is discharged through the three-way exhaust component 12. The three-way exhaust component 12 includes a light component discharge pipe 121, a heavy component discharge pipe 122, a three-way valve 123 and a discharge pipe 124. The light component discharge pipe 121 is connected to the upper part of the air intake tank 1, and the heavy component discharge pipe 122 is connected to the lower part of the air intake tank 1. The three-way valve 123 brings the light component discharge pipe 121, the heavy component discharge pipe 122 and the discharge pipe 124 together. At the same time, the three-way valve 123 only allows one of the light component discharge pipe 121 and the heavy component discharge pipe 122 to be connected to the discharge pipe 124.

[0023] The exhaust gas with a density less than that of air will dissipate and float on the upper part of the air intake tank 1 after entering the air intake tank 1 and flow from the light component discharge pipe 121 to the three-way valve 123. At this time, the light component exhaust gas will squeeze the baffle in the three-way valve 123 downward to block the connecting port between the heavy component discharge pipe 122 and the discharge pipe 124, so that all the light component exhaust gas will pass through the light component discharge pipe 121 and be discharged via the discharge pipe 124. Similarly, the exhaust gas with a density greater than that of air will fall and settle at the bottom of the air intake tank 1 after entering the air intake tank 1 and flow from the heavy component discharge pipe 122 to the three-way valve 123. At this time, the heavy component exhaust gas will squeeze the baffle in the three-way valve 123 upward to block the connecting port between the light component discharge pipe 121 and the discharge pipe 124, so that all the heavy component exhaust gas will pass through the heavy component discharge pipe 122 and be discharged via the discharge pipe 124.

[0024] If the air intake tank 1 is only provided with one exhaust gas emission channel, the experimental exhaust gas needs to fill the air intake tank 1 for a period of time before reaching the position of this emission channel. The exhaust gas cannot immediately enter the absorption component 2 after entering the air intake tank 1, causing a delay in the exhaust gas content data measured by the absorption component 2. The three-way emission component 12 enables the exhaust gas to be discharged quickly and smoothly according to its own density after entering the air intake tank 1 and enter the absorption component 2, thereby avoiding a delay in the measurement data of the absorption component 2.

[0025] The absorption assembly 2 includes a data processing seat 21, an absorption tank 22, an anti-backflow component 23 and a directional drainage pipe 24. The absorption tank 22 is fixedly installed above the data processing seat 21. The data processing seat 21 has a built-in mass sensor and a pH sensor for detecting the quality and pH of the absorption liquid in the absorption tank 22. The anti-backflow component 23 and the directional drainage pipe 24 are installed at the upper end of the absorption tank 22.

[0026] The anti-backflow component 23 includes a buffer ball 231, a fixed connecting pipe 232 and a docking connecting pipe 233. The fixed connecting pipe 232 fixes the buffer ball 231 above the absorption tank 22 and connects the buffer ball 231 with the absorption tank 22. The docking connecting pipe 233 connects the buffer ball 231 to the outside. When assembling the device, the user can connect the docking connecting pipe 233 of an absorption component 2 to the exhaust pipe 124 to guide the exhaust gas to the absorption tank 22 for absorption.

[0027] The branching pipe 24 includes a main riser 241, a three-way branch pipe 242 and a connecting control valve 243. The main riser 241 is installed at the center of the upper axis of the absorption tank 22. The main riser 241 is connected to the absorption tank 22. The absorption liquid can be injected into the absorption tank 22 through the injection port 244 at the upper end of the main riser 241. A one-way valve is installed at the injection port 244 to allow the absorption liquid to enter the absorption tank 22 through the injection port 244. The exhaust gas that is not completely absorbed by the absorption tank 22 cannot be discharged through the injection port 244, but can only be discharged through the three three-way branch pipes 242 arranged on the periphery of the main riser 241.

[0028] The data processing seat 21 is configured as a cubic column, and the three three-way branch pipes 242 and the docking connecting pipe 233 are arranged orthogonally on the four sides of the data processing seat 21 in the same plane, so that when multiple data processing seats 21 are spliced ​​with each other, the docking connecting pipe 233 can correspond to one three-way branch pipe 242 and insert the connecting control valve 243 installed at the end of the three-way branch pipe 242.

[0029] Preferably, magnetic sheets 25 are provided on the four sides of the data processing seat 21 so as to make the data processing seats 21 fit each other stably by means of magnetic force.

[0030] A first docking component 26 is installed below the docking connecting pipe 233, and a second docking component 245 electrically connected to the connecting control valve 243 is installed below the three-way branch pipe 242. Only when the first docking component 26 is connected to the second docking component 245, the connecting control valve 243 will be controlled to open, so that the exhaust gas can only be discharged through the three-way branch pipe 242 connected to the docking connecting pipe 233, and then enter the next absorption component 2.

[0031] The upper surface of the data processing seat 21 is provided with a power connector 27, and an external data line can be connected to the power connector 27 to power the data processing seat 21. The data monitored by the data processing seat 21 can also be transmitted to the outside for summary processing.

[0032] The gas outlet tank 3 is communicated with the three-way branch pipe 242 of the absorption component 2 that finally processes the tail gas, and the tail gas received by the gas outlet tank 3 is finally discharged through the tail gas discharge port 5.
