Description

Zeolite Concentrator Rotor Pollution Prevention Device

Technical Field

The utility model relates to the field of zeolite rotors, in particular to a zeolite concentration rotor pollution prevention device.

Background Art

The zeolite rotor concentrates large-volume, low-concentration exhaust gas into high-concentration, small-volume exhaust gas, thereby reducing the investment and operating costs of the equipment and improving the efficient treatment of VOC exhaust gas. When treating large-volume, low-concentration exhaust gas combustion and recovery, if there is no zeolite rotor and combustion is carried out directly, the exhaust gas treatment equipment is not only bulky, but a cleanliness sensor is usually installed at the front end of the rotor to monitor the passage of particulate matter through the paint mist filter to protect the cleanliness of the zeolite rotor and prevent paint mist particles from damaging the zeolite rotor.

However, when the sensor detects that the paint mist filter has stopped taking in paint mist particles, there are still particles remaining in the filter, which may easily lead to the entry of particles during the continued operation of the zeolite wheel.

DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

As shown in Figures 1-5, this embodiment provides a zeolite concentration wheel pollution prevention device, including a concentration chamber 1, an exhaust gas inlet 3 is installed at one end of the concentration chamber 1, a zeolite wheel 8 is arranged inside the concentration chamber 1, and a protective mechanism 6 is arranged inside the concentration chamber 1 between the zeolite wheel 8 and the exhaust gas inlet 3. The protective mechanism 6 includes: an installation frame 601, a fan blade 603, a closed filter cloth 604, and a storage chamber 606. A rotating shaft is connected between the closed filter cloth 604 and the installation frame 601, the fan blade 603 is movably connected to the installation frame 601, and a winding roller 608 is installed inside the storage chamber 606. The winding roller A motor is installed at one end of 608, and a control circuit is arranged between the motor and the cleanliness detector 607. A binding rope 605 is connected between the winding roller 608 and the closed filter cloth 604. The closed filter cloth 604 and the winding roller 608 are fixedly connected by the binding rope 605. The fan blade 603 is located on the side close to the zeolite rotor 8 and is provided with a cleanliness detector 607. A handle 602 is installed at the outer end of the installation frame 601. The side surface of the concentration chamber 1 is located on the outside of the protective mechanism 6 and is provided with a mounting slot 101. A magnetic pad 609 is installed on the inner side of the installation frame 601 at a position corresponding to the mounting slot 101.

As shown in Figures 2-5, in this embodiment, a joint flange 7 is connected between the exhaust gas inlet 3 and the concentration bin 1, bolts are connected between the exhaust gas inlet 3 and the joint flange 7, a dust filter 301 is installed inside the exhaust gas inlet 3, a desorption outlet 2 is installed on the upper surface of the concentration bin 1 above the zeolite wheel 8, the mounting frame 601 is engaged with the mounting slot 101, the lower end of the zeolite wheel 8 is located outside the concentration bin 1 and a driving mechanism 5 is installed, the exhaust gas outlet 4 is installed at the end of the concentration bin 1 away from the exhaust gas inlet 3, and the desorption outlet 2 and the exhaust gas outlet 4 are both connected to the concentration bin 1.

The working principle of the utility model is as follows: when in use, the exhaust gas is connected to the position of the exhaust gas inlet 3. After the exhaust gas is poured into the interior of the exhaust gas inlet 3, the paint mist will be intercepted under the action of the dust filter 301. The exhaust gas will be poured into the interior of the concentration bin 1 after passing through the exhaust gas inlet 3. When the paint mist remains in the exhaust gas or the dust filter 301 is saturated with adsorption and causes paint mist leakage, it will be blown to the fan blade 603 with the exhaust gas. The cleanliness detector 607 at the rear of the fan blade 603 will generate an electrical signal and transmit it to the motor at the end of the winding roller 608 to control the winding roller 608 to rotate, and the binding rope 605 is wound around the outer end of the winding roller 608 as a whole, so that the closed filter cloth 604 is completely closed inside the mounting frame 601, thereby disconnecting the passage between the exhaust gas inlet 3 and the concentration bin 1. Then, by disconnecting the operation of the driving mechanism 5, the zeolite rotor 8 stops working. After the installation frame 601 is pulled out from the inside of the installation slot 101 as a whole, the use of the dust filter 301 is judged by checking the particle residue above the fan blade 603. When the dust filter 301 as a whole can intercept the paint mist particles normally, the exhaust gas enters the inside of the zeolite rotor 8 and is adsorbed. The gas passing through the zeolite rotor 8 can be directly discharged using the exhaust gas outlet 4. When the zeolite rotor 8 adsorbed with a large amount of VOCs enters high-temperature desorption, the hot air gas with a small air volume desorbs the VOCs molecules on the zeolite rotor and converts them into high-concentration exhaust gas. After the adsorption is completed, it is discharged through the desorption outlet 2 and then burned. The high-temperature gas generated by oxidation is used as regeneration air after heat exchange, thereby achieving energy-saving effect.
