Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, in particular to a self-regulating zeolite wheel purification device based on waste gas concentration. Background Art

[0002] The zeolite wheel device is a rotary adsorption device used for waste gas treatment. Its core is a honeycomb structure composed of zeolite molecular sieves. The zeolite wheel is usually divided into three areas, namely the adsorption zone, the regeneration zone (desorption zone) and the cooling zone. The adsorption zone is responsible for adsorbing organic matter in the waste gas, the cooling zone is used to reduce the temperature of the zeolite, and the regeneration zone releases the adsorbed organic matter by heating the zeolite, thereby realizing efficient treatment of the waste gas through a cycle.

[0003] Although the zeolite wheel can be reused, its service life is limited. As the number of uses increases, the adsorption capacity of the zeolite will gradually decrease. The air inlets of the existing zeolite wheel devices are all fixed, which makes the zeolite molecular sieves that first contact with the exhaust gas fail first, while the other places that have relatively less contact with the exhaust gas do not fail. When replacing, the entire zeolite molecular sieve needs to be replaced, which makes the utilization rate of the zeolite molecular sieve low. In addition, the rotation speed of the zeolite wheel is generally fixed, which makes the zeolite wheel prone to incomplete adsorption when treating high-concentration exhaust gas, and it will generate excess energy consumption when treating low-concentration exhaust gas, which leads to unstable adsorption rate.

A T-shaped annular groove is provided on the side of the deflection seat 32 close to the rotating seat 331. A T-shaped slip ring 336 is fixedly provided on the side of the rotating seat 331 close to the deflection seat 32. The slip ring 336 is inserted into the annular groove and rotates along the annular groove.

[0034] The zeolite wheel assembly 2 comprises a shell 21 and a wheel mechanism 22, wherein the shell 21 is fixedly arranged on the base 1, and the wheel mechanism 22 is rotatably arranged in the shell 21, and three partitions 211 are fixedly arranged on the shell 21, and the three partitions 211 separate the shell 21 into an adsorption chamber 23, a desorption chamber 24 and a cooling chamber 25, and the adsorption chamber 23 is provided with an air inlet 1 and an air outlet 1, and the desorption chamber 24 is provided with an air inlet 2 and an air outlet 2, and the cooling chamber 25 is provided with an air inlet 3 and an air outlet 3, and the air inlet 1, the air inlet 2 and the air inlet 3 are of the same size and are all fixedly installed with a buffer assembly 3;

[0042] During implementation, the exhaust gas is passed into the conical cylinder 31. At this time, the exhaust gas will contact the air guide plate 333, and the air guide ribs 334 on the air guide plate 333 drive the rotating seat 331 to rotate, so that the multiple air guide plates 333 and the air guide curtains form a conical air guide barrier, that is, to guide the exhaust gas to the inner wall of the conical cylinder 31, and then the exhaust gas flows along the conical cylinder 31 to the air inlet 1.

At the same time, the concentration sensor is used to monitor the concentration of the exhaust gas in the conical cylinder, and then the concentration information is transmitted To the control system, the control system adjusts the rotation speed of the wheel mechanism 22 according to this concentration information, thereby avoiding the problem of incomplete exhaust gas adsorption and excessive energy, that is, it not only maintains the constant adsorption efficiency of the zeolite wheel, but also achieves energy saving and consumption reduction. In addition, the flow meter is used to monitor the exhaust gas flow rate of the conical cylinder 31, and the flow data is transmitted to the control system. The control system drives the hydraulic rod 322 to slide along the hydraulic cavity through the hydraulic drive mechanism, thereby causing the deflection rod 332 to deflect, that is, the deflection angle of the air guide plate 333 is changed, and then different wind guide intensities are adjusted to ensure that the exhaust gas concentration and air volume delivered to the output port of the conical cylinder 31, that is, the air inlet, are always uniform, and the buffer component 3 is also set at the air inlet two and the air inlet three, so that the desorption of the zeolite molecular sieve 222 is complete, further improving the utilization rate of the zeolite molecular sieve 222 and extending its service life.

In addition, the concentration of the exhaust gas is detected by a concentration sensor, and the rotation speed of the wheel mechanism 22 in the zeolite wheel assembly 2 is intelligently adjusted by the control system, so that the zeolite wheel assembly 2 maintains a constant adsorption efficiency and achieves energy saving and consumption reduction.
