Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of waste gas treatment, and particularly relates to a water reducing agent waste gas treatment device and a treatment method thereof. BACKGROUND

[0002] The water reducing agent is a kind of concrete additive that can reduce the amount of mixing water while maintaining the slump of concrete basically, and mostly belongs to anionic surfactants, such as lignosulfonate, naphthalene sulfonate formaldehyde polymer, etc. The water reducing agent produces high-temperature waste gas in the production process. If the high-temperature waste gas is directly discharged without treatment, it may affect the environment and human health. In the prior art, the high-temperature waste gas is pretreated to reduce the content of dust and other impurities and to reduce the temperature, and then the treated waste gas is transported to a spray tower for water washing, and then biological treatment is performed to purify the waste gas. The water washing of the spray tower is very important for waste gas treatment.

[0003] A kind of spray tower for chemical waste gas treatment is disclosed in a kind of authorized announcement No. CN118105814B Chinese patent, including spray tower, window, gas-liquid separation structure, baffle one and baffle two, the upper part of baffle one and baffle two is provided with spray structure, the spray structure includes main pipeline, and one side of main pipeline is provided with a group of spray pipes.

[0004] Although the technical scheme in the above patent document realizes convenient maintenance of the spray structure while ensuring spray treatment of the waste gas, it still has the following defects: although the waste gas entering the spray tower has been subjected to the pretreatment step, the content of dust and other impurities and the temperature have been reduced, but the waste gas still inevitably contains dust and other impurities, and the cooling effect of the pretreatment stage is limited, so that the waste gas entering the spray tower still has a certain temperature. The continuous delivery of the waste gas to the spray tower for a long time can accelerate the damage of the internal structure of the spray tower; after the treatment liquid sprayed by the spray tower contacts the waste gas, the waste liquid containing dust and other impurities will be collected at the bottom under the action of gravity, which can easily lead to an increase in the content of impurities in the treatment liquid, and then when the treatment liquid is circulated and sprayed, the impurities can flow with the circulation of the treatment liquid, which not only makes it difficult to ensure the spray treatment effect of the subsequent waste gas, but also easily affects the overall waste gas treatment efficiency.

[0021] The technical scheme of the second aspect is a processing method of a water reducing agent waste gas treatment device, which comprises the following steps:

[0022] Step 1: Equipment pre-run. The liquid circulation component and drive component are started by the external controller to circulate the treatment liquid in the spray tower to the spray mechanism. The treatment liquid is sprayed out from the spray mechanism to spray each packing layer. The operation of the drive component drives the filter component to rotate, so that each striking component is struck and vibrated. The filter component drives the spray mechanism to rotate synchronously through the transmission component, thereby improving the uniformity of the treatment liquid spraying.

[0023] Step 2: Waste gas washing. The pre-treated waste gas is transported from the inlet pipe to the inside of the spray tower through the external fan. The waste gas first comes into contact with the water curtain formed by the treatment liquid to achieve rapid cooling. Then the waste gas flows from bottom to top towards the outlet pipe. After being treated by the double-layer packing layer, the gas comes into contact with the demister body. The demister body removes the mist from the gas, and then the gas is discharged from the outlet pipe.

[0024] Step 3: Waste liquid purification. The treated liquid that has come into contact with the waste gas falls under the action of gravity and then flows into the filter assembly under the collection of the hopper. The waste liquid entering the filter assembly falls onto the umbrella-shaped guide in the filter assembly. Since the filter assembly is rotating at this time, the waste liquid on the umbrella-shaped guide in the filter assembly is thrown onto the peripheral wall of the filter barrel in the filter assembly by centrifugal force. At this time, the synchronous rotation of the filter barrel in the filter assembly realizes the centrifugal separation of the waste liquid. The liquid is thrown out and falls to the bottom of the spray tower for subsequent recycling, while impurities are blocked.

[0025] Step 4: Self-cleaning of impurities. During the rotation of the spray mechanism, each vibrating component in the spray mechanism also moves up and down synchronously. When the vibrating components in the spray mechanism move up and down, they not only vibrate the corresponding carrying mesh, but also drive the scraping parts in the filter assembly to move up and down synchronously through the transmission component. When the scraping parts in the filter assembly move up and down, they scrape and clean the periphery of the filter barrel in the filter assembly. Then, the cleaned impurities fall to the bottom of the filter barrel in the treatment liquid purification mechanism and collect under the action of gravity and some liquid.

[0026] Step 5: Impurity collection. The control valve on the discharge pipe is opened by the external controller, so that the collected impurities are discharged into the storage box by rotating the connector and the discharge pipe.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. By adding a spray element below the bottom packing layer, the sprayed treatment liquid forms a water curtain effect, which can effectively cool the waste gas entering the spray tower and extend the service life of the internal structure of the product.

[0029] 2. The lower part of each filler layer is provided with a vibration assembly, and then the vibration assembly is synchronous with the circular motion of the spraying mechanism during the rotating motion to knock and vibrate the carrier net disc in each filler layer, which on one hand speeds up the falling speed of the liquid drops, and on the other hand, the vibration of the carrier net disc makes the filler carried on it shake, avoids the blockage of the holes of the filler due to long-term contact with the waste gas, and guarantees the effect of the device on the waste gas treatment;

[0030] 3. The inside of the spraying tower is provided with a treatment liquid purification mechanism, which intercepts the liquid contacted with the waste gas, and realizes the filtration treatment of the liquid in this state by using the centrifugal force, guarantees the effectiveness of the treatment liquid in the recycling, and the high efficiency of the waste gas treatment;

[0031] 4. The driving assembly in the treatment liquid purification mechanism drives the rotation of the filtering assembly, and the filtering assembly drives the rotating activity of the spraying mechanism through the transmission assembly during the rotation, improves the spraying range of the treatment liquid, and the transmission assembly also transmits the lifting force of the bottom vibration assembly under the transmission of the rotating force, so that the scraping member in the filtering assembly lifts and moves, realizes the scraping and cleaning of the inner wall of the filtering barrel;

[0032] 5. The filtering assembly in the treatment liquid purification mechanism adjusts the synchronous driving knocking assembly during the rotation, and then knocks and vibrates the filtering barrel and the hopper, which on one hand speeds up the speed of the liquid containing impurities into the filtering barrel, and on the other hand, facilitates the quick collection of the impurities attached to the inner wall of the filtering barrel, and reduces the risk of clogging of the mesh.

[0082] The application provides a treatment method of a water reducing agent waste gas treatment device.

[0083] Step one: equipment pre-operation, the liquid circulating assembly 7 and the driving assembly 64 in the treatment liquid purification mechanism 6 are started by the external controller main body, at this time, the circulating water pump in the liquid circulating assembly 7 circulates and delivers the treatment liquid in the spraying tower 1 into the spraying mechanism 5, the treatment liquid is sprayed out of each spraying piece 53 in the spraying mechanism 5, the spraying of each filler layer is realized, and the treatment liquid sprayed out of the bottommost spraying piece 53 forms a water curtain, which is used for contact cooling of the waste gas entering into the spraying tower 1.

[0084] The operation of the driving assembly 64 drives the filter assembly 63 to rotate, so that each knocking assembly 65 knocks and vibrates, and the movement of the filter assembly 63 synchronously drives the spraying mechanism 5 to rotate synchronously through the transmission assembly 66, so as to improve the uniformity of the spraying of the treatment liquid.
