Description

Technical Field

[0001] This utility model belongs to the field of waste gas treatment technology, and in particular relates to an activated carbon adsorption system. Background Technology

[0002] Currently, chemical analysis is needed to analyze each reaction process in the production of polyester resin products in order to better implement the production of polyester resin products. During the chemical analysis in the laboratory, some volatile organic gases will be released. According to national regulations, the released organic gases need to be collected in an organized manner by a fan and adsorbed by activated carbon filtration. Only after meeting the established emission standards can they be released into the atmosphere.

[0003] However, activated carbon itself is a flammable material and can easily combust under certain conditions. Furthermore, during the adsorption process, activated carbon accumulates large amounts of organic solvents and flammable substances. This accumulation, especially when the temperature rises or it encounters a source of ignition, increases the risk of fire and explosion. Traditional activated carbon adsorption systems do not include fire protection units, and the occurrence of a fire or explosion could lead to severe consequences. Utility Model Content

[0004] In view of the problems existing in the prior art, the main purpose of this utility model is to provide an activated carbon adsorption system. The provided activated carbon adsorption system has a simple structure, reliable operation, and can effectively reduce system maintenance costs and downtime.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] This utility model provides an activated carbon adsorption system, the activated carbon adsorption system comprising:

[0007] A gas collection pipeline, wherein the gas collection pipeline is provided with a gas inlet and a gas outlet;

[0008] An activated carbon box is connected to the gas collecting pipeline and is located between the gas inlet and the gas outlet; a temperature sensor is also installed inside the activated carbon box.

[0009] The spray pipeline has an inlet and an outlet, and the outlet is connected to multiple spray heads located in the activated carbon box; the spray pipeline is also equipped with a solenoid valve, which is electrically connected to the temperature sensor.

[0010] As a further description of the above technical solution, the spray head is a thermal glass ball spray head.

[0011] As a further description of the above technical solution, a fan is provided on the gas collection pipeline, and the fan is located between the gas outlet and the activated carbon box in the gas flow direction.

[0012] As a further description of the above technical solution, it also includes an intelligent control unit, wherein the fan, solenoid valve and temperature sensor are all connected to the intelligent control unit; thereby the intelligent control unit can control the opening and closing of the fan and the solenoid valve according to the temperature signal returned by the temperature sensor.

[0013] As a further description of the above technical solution, a main valve is also provided between the water inlet of the spray pipeline and the solenoid valve, and the main valve is kept in a normally open state.

[0014] As a further description of the above technical solution, the solenoid valve is also connected in parallel with a shut-off valve, which is kept in a normally closed state.

[0015] Based on the above technical solutions, the outstanding effects of this utility model are as follows:

[0016] 1. In the activated carbon adsorption system provided by this utility model, the activated carbon box is still connected to the gas collection pipeline and is located between the gas inlet and outlet of the gas collection pipeline. This allows the organic waste gas from the laboratory to enter the gas collection pipeline through the inlet and first pass through the activated carbon in the activated carbon box for filtration and adsorption of harmful substances, ensuring that the waste gas meets purification standards before being discharged into the atmosphere through the outlet. The difference is that a temperature sensor is added to the activated carbon box, along with a spray pipeline. The spray pipeline has an inlet and an outlet, and the outlet is connected to multiple spray heads located inside the activated carbon box. An electromagnetic valve is also installed on the spray pipeline, electrically connected to the temperature sensor. Therefore, if the activated carbon box catches fire, and the temperature sensor detects that the temperature inside the activated carbon box is too high, it will interlock and open the electromagnetic valve, connecting the inlet and outlet, allowing the spray heads to perform fire extinguishing spraying on the activated carbon box. This reliably ensures that the activated carbon box will not catch fire or explode, effectively reducing system maintenance costs and downtime caused by fire or explosion.

[0017] 2. The spray head used in the activated carbon adsorption system provided by this utility model is a thermal glass ball spray head, which can effectively prevent the activated carbon box from being accidentally sprayed when the solenoid valve has internal leakage or malfunction, thus affecting the adsorption effect of the activated carbon inside, thereby improving the safety and reliability of the system.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

They are used only for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The implementation methods of this utility model will now be described based on its overall structure.

[0023] Please see Figure 1 This utility model discloses an activated carbon adsorption system, which includes:

[0024] Gas collection pipe 1, wherein the gas collection pipe 1 is provided with an air inlet and an air outlet;

[0025] Activated carbon box 2 is connected to the gas collection pipe 1 and is located between the gas inlet and the gas outlet; a temperature sensor 3 is also provided inside the activated carbon box 2.

[0026] The spray pipe 4 is provided with an inlet and an outlet. The outlet is connected to multiple spray heads 5 located in the activated carbon box 2. The spray pipe 4 is also provided with a solenoid valve 6, which is electrically connected to the temperature sensor 3.

[0027] In the above configuration, the activated carbon box 2 is still connected to the gas collection pipeline 1 and is located between the inlet and outlet of the gas collection pipeline 1. This allows the organic waste gas from the laboratory to enter the gas collection pipeline 1 through the inlet and be filtered and adsorbed by the activated carbon in the activated carbon box 2 before being discharged into the atmosphere through the outlet after the waste gas meets the purification standards. The difference lies in the installation of a temperature sensor 3 within the activated carbon box 2, along with a spray pipe 4. The spray pipe 4 has an inlet and an outlet, with the outlet connected to multiple spray heads 5 located within the activated carbon box 2. A solenoid valve 6 is also installed on the spray pipe 4, electrically connected to the temperature sensor 3. Therefore, if the activated carbon box 2 catches fire, and the temperature sensor 3 detects excessively high temperatures within the activated carbon box 2, it will interlock and open the solenoid valve 6, connecting the inlet and outlet, allowing the spray heads 5 to perform fire extinguishing spraying on the activated carbon box 2. This reliably ensures that the activated carbon box 2 will not catch fire or explode, effectively reducing system maintenance costs and downtime caused by fire or explosion.

[0028] Please see Figure 1 Specifically, in this embodiment, the water inlet of the spray pipe 4 can be connected to an external water source.

[0029] Specifically, in this embodiment, the spray head 5 is a thermosensitive glass bulb spray head 5. When the temperature inside the activated carbon box 2 reaches a preset upper limit, the organic solution inside the thermosensitive glass bulb of the spray head 5 will expand and break due to heat. At the same time, the solenoid valve 6 will open, connecting the spray pipe 4 with the inlet and outlet, thereby enabling the spray head 5 to start spraying. However, if the solenoid valve 6 has internal leakage or malfunctions, the temperature inside the activated carbon box 2 is insufficient to cause the organic solution inside the thermosensitive glass bulb of the spray head 5 to expand and break due to heat. Therefore, the spraying operation will not be carried out, effectively avoiding the situation where the activated carbon box 2 is accidentally sprayed, affecting the adsorption effect of the activated carbon inside, thus improving the safety and reliability of the system.

[0030] Specifically, in this embodiment, a fan 7 is installed on the gas collection pipeline 1. In the gas flow direction, the fan 7 is located between the gas outlet and the activated carbon box 2, so that the organic waste gas in the laboratory can be quickly purified by the activated carbon before being discharged from the gas outlet. It should be understood that adjusting the speed of the fan 7 can effectively control the rate at which the organic waste gas passes through the activated carbon box 2, so as to ensure that the purification of the organic waste gas meets the standards.

[0031] Specifically, in this embodiment, the activated carbon adsorption system further includes an intelligent control unit 8. The fan 7, solenoid valve 6, and temperature sensor 3 are all connected to the intelligent control unit 8. Thus, the intelligent control unit 8 can control the opening and closing of the fan 7 and the solenoid valve 6 based on the temperature signal returned by the temperature sensor 3. In other words, when the activated carbon adsorption system is working normally, the fan 7 is in the on state, the solenoid valve 6 is in the off state, and the temperature sensor 3 transmits the temperature inside the activated carbon box 2 back to the intelligent control unit 8 in real time. Once the temperature signal returned by the temperature sensor 3 to the intelligent control unit 8 reaches the upper limit value, the intelligent control unit 8 will issue a shutdown command to the fan 7 to stop its operation, thereby preventing exhaust gas from re-entering the activated carbon box 2. Simultaneously, it will issue an opening command to the solenoid valve 6, connecting the inlet and outlet of the spray pipe 4, allowing multiple spray heads 5 connected to the outlet to spray the activated carbon box 2 for fire extinguishing / cooling.

[0032] Specifically, in this embodiment, a main valve 9 is provided between the water inlet of the spray pipe 4 and the solenoid valve 6. The main valve 9 is kept in a normally open state. When it is necessary to replace or repair the solenoid valve 6 and other components of the spray pipe 4, the main valve 9 can be closed first. Therefore, the setting of the main valve 9 facilitates the replacement and repair of the solenoid valve 6 and other components of the spray pipe 4.

[0033] Specifically, in this embodiment, the solenoid valve 6 is also connected in parallel with a shut-off valve 10, which is kept in a normally closed state. When the solenoid valve 6 malfunctions and the temperature in the activated carbon box 2 reaches the upper limit, the shut-off valve 10 can be manually opened to connect the inlet and outlet of the spray pipe 4, so that the spray head 5 can still spray in real time.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any changes, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
