Description

Technical Field

[0001] The present invention relates to the technical field of gas purification, and in particular to a gas processing device and a method for purifying polluted gas. Background Art

[0002] With the economic development of society, air quality has become an issue that we cannot avoid. The continuous increase of various industrial waste gases, the increasing automobile exhaust, and the volatile organic pollutant gases emitted by various building materials seriously threaten our health. In order to improve the quality of life, people will choose gas purification devices to improve the surrounding gas environment.

[0003] There are many types of tail gas treatment devices in the current chemical industry, most of which are based on chemical reaction treatment and porous material adsorption reprocessing. The common operation of the current porous material adsorption equipment is to replace the adsorption material from time to time. This is bound to lead to the problem that the adsorption material may be discarded before it reaches saturation, resulting in material waste and increased costs; there may also be problems with the adsorption material being oversaturated but still in use, resulting in incomplete and unstable exhaust gas treatment. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide a gas treatment device which can save materials, has low cost, is easy to operate, and can treat waste gas stably and thoroughly.

[0005] The technical solution of the present invention is:

[0006] A gas treatment device comprises a tower body, wherein the tower body is provided with an air inlet, an air outlet, a feeding hole and a discharge port, the inner cavity of the tower body is divided into at least two stacked filling chambers by a partition, the filling chambers are filled with gas treatment fillings, and the partition is provided with a plurality of through holes; the positions of the air inlet and the air outlet are arranged so that the gas passes through the stacked filling chambers from bottom to top and is discharged in sequence, and the partition is configured as a movable partition that can make the fillings in the upper filling chamber fall into the filling chamber in the lower layer. The gas in the tower body flows from bottom to top, and as the gas is purified by the fillings in the tower body, the gas pollutant concentration decreases as it goes up, and the gas pollutant concentration at the lower part of the tower body is higher, so the filling at the lower part of the tower body is consumed faster and reaches saturation earlier than the filling at the lower part of the tower body. At this time, if the filling in the entire tower body is replaced, the filling at the upper part of the tower body that has not reached saturation is not fully utilized, resulting in waste; if the filling is not replaced, the saturated filling in the filling chamber at the lower part of the tower body cannot play a role in treating the gas, and the treatment effect of the gas treatment device is not ideal. The gas processing device of the present invention uses a partition with a through hole to divide the tower body into a plurality of packing chambers, and the partition is movable. When the packing in the bottom packing chamber reaches saturation, the packing in the bottom packing chamber is discharged from the discharge port by moving the partition of the bottom packing chamber. The partitions of each packing chamber are moved separately, and the packing in the upper packing chamber falls into the lower packing chamber due to gravity and continues to be used, thereby making full use of the packing in the tower body; new packing is timely added to the top packing chamber in the tower body, and sufficient unsaturated packing is maintained in the tower body, so that the gas processing is more stable and thorough.

[0007] Preferably, in the above-mentioned gas processing device, the air inlet is arranged at the bottom of the tower body, the air outlet is arranged at the top of the tower body, the air outlet is connected to an air outlet pipe, and the air outlet pipe is provided with an induced draft fan. Under the guidance of the induced draft fan, the gas enters the tower body from the air inlet at the bottom of the tower body, and a through hole is provided on the partition plate in the inner cavity of the tower body, and the gas passes through each of the stacked packing chambers from bottom to top in sequence and is discharged from the outlet.

[0008] Preferably, in the above-mentioned gas treatment device, at least three packing chambers are provided, and at least one packing chamber is provided with a detection device. When there are multiple packing chambers, a detection device is installed, and the detection device prompts the material change time, the waste material in the tower body is discharged in time, and new packing is added to the tower body, so that the gas treatment stability of the gas treatment device is better.

[0009] More preferably, in the above-mentioned gas treatment device, a detection device for detecting the concentration of pollutants in the second packing chamber from the bottom to the top is provided in the second packing chamber of the tower body, and the detection device is specifically arranged in the cavity between the second packing chamber and the third packing chamber above it. By optimizing the specific position of the detection device, the residual concentration of gas pollutants can be better detected. Since there is sufficient gas in the cavity, the detection result is more accurate, and the material change reminder time of the detection device is more accurate.

[0010] Preferably, in the above-mentioned gas processing device, a discharge baffle is further provided at the discharge port, and the discharge baffle divides the discharge port into a waste accumulation area and an external discharge area. The discharge baffle can maintain the airtightness of the tower body, and the waste is accumulated in the waste accumulation area, so that the waste at the discharge port does not need to be processed every time the material is changed, saving working time.

[0011] Preferably, in the above-mentioned gas processing device, the movable partition is a removable movable partition, which can be pulled out of the tower body to make the filler in the upper packing chamber fall into the packing chamber or the discharge port of the lower layer, and can be re-inserted to separate the packing chambers of the upper and lower adjacent layers. The removable movable partition has a simple structure, good stability, easy operation, and more convenient material replacement.

[0012] Preferably, in the above-mentioned gas treatment device, the movable partition can also be a rotatable multi-blade combination plate, which rotates some of the blades in the tower to make part of the filler in the upper packing chamber fall into the packing chamber or the discharge port of the lower layer, and then rotates the remaining blades to make the remaining filler in the upper packing chamber fall into the packing chamber or the discharge port of the lower layer, and finally restores the packing chambers of the upper and lower adjacent layers to separate again. The gas in the packing chamber is mostly harmful gas, which may cause harm to personnel. The rotatable multi-blade combination plate is used as a partition, and the material change work is completed in the tower body to avoid the harmful gas in the tower body flowing to the outside of the tower body to cause harm and pollute the environment. The temperature of the filler in the packing chamber is relatively high. If it is brought outside the tower body, it is easy to cause burns to personnel. The rotatable multi-blade combination plate is used as a partition, and the material change work is completed in the tower body to avoid burns to personnel, and the material change work is safer.

[0013] As a general inventive concept, the present invention also provides a method for purifying polluted gas using the above-mentioned gas processing device, comprising the following steps:

[0014] S1: Filling all the packing chambers of the gas treatment device with packing for purifying gas through the feeding holes;

[0015] S2: Turn on the induced draft fan to allow the gas to pass through all the packing chambers of each layer from bottom to top, and finally be discharged from the air outlet;

[0016] S3: operating the gas treatment device continuously and detecting the concentration of gas pollutants in the packing chamber by the detection device;

[0017] S4: When the data fed back by the detection device reaches the set threshold, it will remind you to start replacing the packing;

[0018] S5: When replacing the packing, first pull out the lowermost partition from the tower body, so that the packing in the lowermost packing chamber falls into the discharge port, and then reinsert the partition to keep the lowermost packing chamber empty;

[0019] S6: Pulling out the partition of the upper layer from the tower body, so that the filler in the packing chamber of the upper layer falls into the packing chamber of the lowest layer, and then reinserting the partition of the layer so that the packing chamber of the layer remains empty;

[0020] S7: Repeat this process until the uppermost packing chamber remains empty, and then new material is added to the uppermost packing chamber through the feeding hole, and then the feeding hole is sealed and the operation is restarted.

[0021] The above method is used to purify the gas. The movable partition adopts a pluggable partition, which has a simple structure, good stability, easy operation, and more convenient material replacement. The pluggable partition divides the tower body into multiple packing chambers. When the packing in the bottom packing chamber reaches saturation, it is only necessary to discharge the packing in the bottom packing chamber first, and then fill the packing in the upper packing chamber to the adjacent next packing chamber in turn for continued use, thereby improving the utilization rate of the packing; new packing is added to the top packing chamber in the tower body in time, and sufficient unsaturated packing is maintained in the tower body, so that the gas treatment is more stable and thorough.

[0022] As a general inventive concept, the present invention also provides another method for purifying polluted gas using the above-mentioned gas treatment device, comprising the following steps:

[0023] S1: Filling all the packing chambers of the gas treatment device with packing for purifying gas through the feeding holes;

[0024] S2: Turn on the induced draft fan to allow the gas to pass through all the packing chambers of each layer from bottom to top, and finally be discharged from the air outlet;

[0025] S3: operating the gas treatment device continuously and detecting the concentration of gas pollutants in the packing chamber by the detection device;

[0026] S4: When the data fed back by the detection device reaches the set threshold, it will remind you to start replacing the packing;

[0027] S5: When replacing the filler, first rotate part of the blades in the lowermost partition to open one side of the partition first, and allow part of the filler in the lowermost filling chamber to fall into the discharge port through the opening, then rotate the aforementioned part of the blades and simultaneously rotate the remaining part of the blades to open the other side, and allow the remaining part of the filler in the lowermost filling chamber to fall into the discharge port through the opening on the other side, and then rotate to keep the lowermost filling chamber empty;

[0028] S6: Rotate some of the blades in the partition of the upper layer to open one side of the partition first, and make some of the stuffing in the stuffing chamber of the upper layer fall into the stuffing chamber of the lowest layer through the opening, then rotate the aforementioned part of the blades and rotate the remaining part of the blades at the same time to open the other side, and make the remaining part of the stuffing in the stuffing chamber of the upper layer fall into the stuffing chamber of the lowest layer through the opening of the other side, and then rotate to keep the stuffing chamber of the upper layer empty;

[0029] S7: Repeat this process until the uppermost packing chamber remains empty, and then new material is added to the uppermost packing chamber through the feeding hole, and then the feeding hole is sealed and the operation is restarted.

[0030] The gas is purified by the above method, and a rotatable multi-blade combination plate is used as a partition. The material change work is completed in the tower body to prevent harmful gases in the tower body from flowing out of the tower body to cause harm and pollute the environment. The temperature of the filler in the packing room may be high. If it is taken out of the tower body, it is easy to cause burns to personnel. A rotatable multi-blade combination plate is used as a partition, and the material change work is completed in the tower body, which is safer. The rotatable partition divides the tower body into multiple packing chambers. When the filler in the bottom packing chamber reaches saturation, it is only necessary to discharge the filler in the bottom packing chamber first, and then fill the filler in the upper packing chamber to the adjacent next packing chamber in turn for continued use, thereby improving the utilization rate of the filler; new filler is added to the top packing chamber in the tower body in time, and sufficient unsaturated filler is maintained in the tower body, so that the gas treatment is more stable and thorough.

[0031] Compared with the prior art, the advantages of the present invention are:

[0032] The gas processing device of the present invention uses movable partitions to divide the tower body into multiple packing chambers. When the packing in the lowest packing chamber reaches saturation, it is only necessary to discharge the packing in the lowest packing chamber first, and then fill the packing in the upper packing chamber into the adjacent next packing chamber in turn for continued use, thereby improving the utilization rate of the packing; new packing is added to the uppermost packing chamber in the tower body in time, and sufficient unsaturated packing is maintained in the tower body, so that the gas processing is more stable and thorough.
