Industrial waste gas discharged into the atmosphere will pollute the air and seriously endanger human health if it enters the human body.

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] The invention discloses a safe diluter for explosive waste gas of large air volume in polymer production, which is mainly used in scenarios where it is impossible to safely treat waste gas of different concentrations at low operating costs.

[0029] Reference Figure 1-8 A safe diluter for explosive waste gas of large air volume waste gas in polymer production, comprising a low-concentration tube 1 and a high-concentration tube 2, wherein a part of the tube body of the high-concentration tube 2 is located inside the low-concentration tube 1, the high-concentration tube 2 is connected to the low-concentration tube 1 by bolts, and the low-concentration tube 1 comprises a mixing tube 3 and an auxiliary tube 4, a mixing promotion component 5 is arranged inside the mixing tube 3, the mixing promotion component 5 comprises a low-concentration flow increaser 501, a mixing frame 504 and a high-concentration diffuser 506, the low-concentration flow increaser 501 is located outside the high-concentration tube 2, a plurality of variable flow holes 502 are opened on the low-concentration flow increaser 501, the apertures of the plurality of variable flow holes 502 are all funnel-shaped, the plurality of variable flow holes 502 are located outside the high-concentration tube 2 and are equidistantly distributed around the circumference, and a spherical contact 503 is arranged on the low-concentration flow increaser 501, and the spherical contact 503 is located at one end of the large aperture of the variable flow hole 502.

[0030] Specifically, the low-concentration aerobic waste gas is transported into the low-concentration tube 1, and the high-concentration oxygen-free waste gas is transported into the high-concentration tube 2. The low-concentration aerobic waste gas is pressurized by the mixing promotion component 5 to change the airflow transport state to form a spiral airflow. The high-concentration oxygen-free waste gas is dispersed by the mixing promotion component 5 and enters the low-concentration tube 1 in a divergent state. The spiral low-concentration aerobic waste gas and the divergent high-concentration oxygen-free waste gas are mixed and diluted in front of the auxiliary tube 4. The device uses the mixing promotion component 5 to pressurize the low-concentration aerobic waste gas to form a spiral airflow, and transports the high-concentration oxygen-free waste gas into the low-concentration tube 1 in a divergent state, so that the airflows of the low-concentration aerobic waste gas and the high-concentration oxygen-free waste gas are in right-angle contact in the low-concentration tube 1, thereby increasing the contact and mixing effect between the two, thereby improving the degree of mixing and dilution between the two.

An auxiliary flow head 508 is arranged inside the high-concentration diffusion tube 506, and the auxiliary flow head 508 is opposite to the inner cavity of the high-concentration tube 2.

[0032] Specifically, when the low-concentration oxygen-containing waste gas flows through the low-concentration flow-increasing platform 501, the low-concentration oxygen-containing waste gas increases its overall flow rate due to the change in the aperture of the variable flow hole 502, and then enters the mixing frame 504, and uses the momentum of the airflow to drive the mixing frame 504 to rotate. The airflow forms a spiral airflow under the limiting effect of the spiral mixing blade 505; the high-concentration oxygen-free waste gas flows through the high-concentration tube 2 and enters the high-concentration diffuser 506. Under the guidance of the auxiliary flow head 508, the high-concentration oxygen-free waste gas changes its horizontal airflow state, and enters the inner cavity of the low-concentration tube 1 from the diffuser blade 507 and impacts the inner wall of the low-concentration tube 1 and is rebounded to form a divergent airflow;

[0033] In a specific application scenario, the mixing promotion component 5 is suitable for the mixing link of low-concentration aerobic exhaust gas and high-concentration oxygen-free exhaust gas in the low-concentration tube 1, that is, the mixing promotion component 5 can change the flow rate and airflow state of the low-concentration aerobic exhaust gas, increase its speed and form a swirling airflow, and change the high-concentration oxygen-free exhaust gas to form a divergent airflow when it enters the inner cavity of the low-concentration tube 1, thereby improving the contact state between the low-concentration aerobic exhaust gas and the high-concentration oxygen-free exhaust gas and increasing the mixing effect between the two; the spherical contact 503 and the auxiliary flow head 508 can both improve the smoothness of the airflow when it changes its state at its position.

[0034] Reference Figure 1 , Figure 2 and Figure 5 A low-concentration air inlet 6 and a primary mixing exhaust port 7 are respectively provided at both ends of the low-concentration tube 1. The low-concentration air inlet 6 is located at one end of the low-concentration tube 1 close to the mixing tube 3, and the primary mixing exhaust port 7 is located at one end of the low-concentration tube 1 close to the auxiliary tube 4, and a safety auxiliary module 8 is provided on the auxiliary tube 4; the safety auxiliary module 8 includes a temperature control box 801, which is located outside the auxiliary tube 4 and connected by bolts, and a temperature control display screen 802 is provided on the temperature control box 801, and a plurality of circumferentially equidistant mounting holes are provided on the auxiliary tube 4, and heat sinks 803 are connected inside the mounting holes by bolts, and a plurality of heat sinks 803 are provided with a plurality of equidistant contact-enhancing grooves 804, and the contact-enhancing grooves 804 are all located inside the auxiliary tube 4, and the same condenser 805 is provided outside the plurality of heat sinks 803, and the condenser 805 is located inside the temperature control box 801.

[0035] Specifically, the two exhaust gases after preliminary mixing enter the auxiliary pipe 4, and the preliminary mixed airflow contacts the heat sink 803, and the condenser 805 is always in operation to cool the heat sink 803, thereby changing the overall temperature of the mixed gas;

[0036] In a specific application scenario, the safety auxiliary module 8 is suitable for the temperature control link of the gas after preliminary mixing, that is, the safety auxiliary module 8 uses multiple heat sinks 803 to cool the exhaust gas after preliminary mixing inside the auxiliary pipe 4, so as to avoid the temperature increase of the gas in the pipe due to the collision between the gases during the mixing of the two exhaust gases, thereby increasing the risk of explosion; the contact increasing grooves 804 on the heat sink 803 can increase the contact effect with the gas, and at the same time, the multiple heat sinks 803 are equidistantly distributed in a circle inside the auxiliary pipe 4, which can further divide the airflow passing through, thereby improving the mixing degree of the airflow.

[0038] Specifically, when the high-concentration oxygen-free waste gas is transported in, its air pressure can be adjusted by the air pressure pump 11 at the pressure regulating pipe 9, thereby changing the flow rate of the high-concentration oxygen-free waste gas (the flow rate of the low-concentration oxygen-containing waste gas in the low-concentration pipe 1 is limited. When the degree of mixing between the two deteriorates, it can be adjusted by changing the flow rate of the high-concentration oxygen-free waste gas).

[0039] Reference Figure 1 , Figure 6 and Figure 7 A ball bin 12 is provided on one side of the low concentration tube 1, a support frame 13 is connected to the outside of the ball bin 12 by bolts, a secondary air inlet 14 is provided on the ball bin 12, and the secondary air inlet 14 is connected to the primary mixing exhaust port 7 by a flange; an external discharge port 15 is provided on the upper side of the ball bin 12, and a secondary dilution assembly 16 is provided on the ball bin 12; the secondary dilution assembly 16 includes a shaft 1601, and a plurality of multi-rotation dilution blades with equidistant circumferences are connected to the outside of the shaft 1601 by bolts 1602, the multiple multi-rotation dilution blades 1602 are all located inside the ball bin 12, and the multiple multi-rotation dilution blades 1602 are all provided with multiple equidistant overflow grooves 1603, and the outside of the ball bin 12 is connected to a motor frame 1604 by bolts, the motor frame 1604 is located on the side of the ball bin 12 opposite to the secondary air inlet 14, and a dilution motor 1605 is connected to the motor frame 1604 by bolts, and the dilution motor 1605 is connected to the shaft 1601 by a coupling.

[0040] Specifically, the initially mixed exhaust gas after cooling enters the interior of the ball bin 12 from the secondary air inlet 14, the dilution motor 1605 drives the shaft 1601 to rotate, and the multi-rotation dilution blades 1602 rotate inside the ball bin 12 to stir the exhaust gas in the ball bin 12, thereby increasing the mixing degree of the exhaust gas, and then the exhaust gas that has completed mixing and dilution is discharged from the external discharge port 15;

[0041] In a specific application scenario, the secondary dilution component 16 is suitable for the secondary mixing and dilution of the exhaust gas after the initial mixing, that is, the secondary dilution component 16 utilizes the rotating multi-rotation dilution blades 1602 to stir and mix the initially mixed exhaust gas again inside the ball bin 12, so as to further improve the mixing and dilution effect of the two exhaust gases; the rotation direction of the multi-rotation dilution blades 1602 is opposite to the rotation direction of the spiral mixing blades 505 in the mixing promotion component 5, so as to achieve the purpose of changing the airflow state multiple times in the ball bin 12 (the circulating exhaust gas impacts the inner wall of the ball bin 12 and is rebounded to form a divergent airflow; the spiral circulating airflow contacts the spiral circulating airflow in the ball bin 12, and the two circulation directions are opposite).

[0042] Reference Figure 1 and Figure 6 The lower side of the ball bin 12 is connected to a bottom seat 17 by bolts, and two mounting holes are provided on the bottom seat 17, and both mounting holes are connected to the inner cavity of the ball bin 12; the support frame 13 is connected to an equipment frame 18 by bolts, and the equipment frame 18 is connected to a gas analyzer 19 by bolts, and the gas analyzer 19 is provided with an inlet and an outlet, and the inlet and the outlet are respectively connected to a gas supply pipe 20 and a return pipe 21 by bolts, and the other ends of the gas supply pipe 20 and the return pipe 21 are respectively connected to the two mounting holes on the bottom seat 17 by bolts.

[0043] Specifically, during the mixing and dilution process, the gas analyzer 19 is always in working condition, and performs real-time monitoring of the exhaust gas in the spherical bin 12 to ensure that the exhaust gas after mixing and dilution meets the treatment standards.

[0044] Working principle: When the device is installed in the exhaust gas treatment workshop, the low-concentration tube, high-concentration tube and ball bin need to be well grounded to avoid any safety hazards caused by static electricity;

[0045] When in use, the low-concentration oxygen waste gas is transported into the low-concentration tube 1, and the high-concentration oxygen-free waste gas is transported into the high-concentration tube 2. The low-concentration oxygen waste gas is pressurized by the mixing component 5 to change the airflow transport state, so that it forms a spiral airflow (when the low-concentration oxygen waste gas flows through the low-concentration flow increaser 501, due to the change in the aperture of the variable hole 502, the low-concentration oxygen waste gas increases the overall flow rate, and then enters the mixing frame 504. The flow frame 504 is driven to rotate by the impulse of the airflow, and the airflow forms a spiral under the limiting effect of the spiral mixing blade 505. airflow), the high-concentration oxygen-free waste gas is dispersed by the mixing promotion component 5 and enters the low-concentration tube 1 in a divergent state (the high-concentration oxygen-free waste gas flows in the high-concentration tube 2 and enters the high-concentration diffuser 506. Under the guidance of the auxiliary flow head 508, the high-concentration oxygen-free waste gas changes the horizontal airflow state, and the high-concentration oxygen-free waste gas enters the inner cavity of the low-concentration tube 1 from the diffuser blade 507 and impacts the inner wall of the low-concentration tube 1 and is rebounded to form a divergent airflow), the swirling low-concentration oxygen-containing waste gas and the divergent high-concentration oxygen-free waste gas are mixed and diluted in front of the auxiliary tube 4;

[0046] After the initial mixing, the two exhaust gases enter the auxiliary pipe 4. The initial mixed airflow will contact the heat sink 803. The condenser 805 is always in operation to cool the heat sink 803, thereby changing the overall temperature of the mixed gas. The initially mixed exhaust gas after cooling enters the interior of the ball bin 12 from the secondary air inlet 14. The dilution motor 1605 drives the shaft 1601 to rotate, and the multi-rotation dilution blades 1602 rotate inside the ball bin 12 to stir the exhaust gas in the ball bin 12, thereby increasing the mixing degree of the exhaust gas. Then, the exhaust gas that has completed the mixing and dilution is discharged from the external discharge port 15.

[0047] During the mixing and dilution process, the gas analyzer 19 is always in working condition, and the exhaust gas in the ball bin 12 is monitored in real time to ensure that the exhaust gas after mixing and dilution meets the treatment standards.
