Description

Technical Field

[0001] The present invention relates to the field of waste gas treatment, and particularly relates to a high-concentration high-temperature waste gas treatment device for a chemical reaction kettle and a using method thereof. Background Technique

[0002] The general understanding of a reaction kettle is a container with physical or chemical reactions. Through the structural design and parameter configuration of the container, functions such as heating, evaporation, cooling, and mixing at low and high speeds required by the process are realized. Reaction kettles are widely used in fields such as petroleum, chemical industry, rubber, pesticides, dyes, medicine, food, etc. The materials are generally carbon manganese steel, stainless steel, and other composite materials. Since chemical reactions are usually carried out inside the reaction kettle more often, correspondingly, while the reaction is taking place, waste gas generated by the chemical reaction will be discharged. Therefore, a waste gas treatment device for a chemical reaction kettle is used to carry out corresponding treatment on the waste gas.

[0003] After retrieval, the publication (announcement) number: CN217961967U discloses a reaction kettle waste gas treatment device, including a bottom plate. One side above the bottom plate is provided with a water tank, and one side above the water tank is provided with a fan. The output end of the fan extends to the inner bottom of the water tank through a pipeline. One side of the water tank is provided with a drying box. The gas collection tray is connected to the drying box through a pipeline. One side of the drying box away from the water tank is provided with a filtering tank. One side of the drying box close to the filtering tank is provided with a second gas collection tray. The second gas collection tray is connected to the filtering tank through a pipeline. A support ring is provided at the lower end inside the filtering tank, and an activated carbon filtering layer is provided above the support ring. A discharge pipe is provided in the middle above the filtering tank. This kind of waste gas treatment device has a simple structure, is easy to operate, has a good filtering effect, avoids the filtering effect of the activated carbon filtering layer from being affected, and effectively guarantees the purification effect of the waste gas treatment device.

[0004] Although the above solution can effectively guarantee the purification effect of the waste gas treatment device, the synthesis reaction in the reaction kettle usually needs to be heated, or the exothermic reaction generates heat, which increases the temperature of the materials in the reaction kettle, thus significantly increasing the organic matter concentration and heat in the gas phase at the top of the reaction kettle. After that, it is directly discharged to the treatment device for purification without a waste heat recovery device, resulting in the waste of heat in the gas and causing waste of resources.

[0019] A method for using a high-concentration high-temperature waste gas treatment device for a chemical reaction kettle, characterized by comprising the following steps:

[0020] S1. Waste gas transportation: Extract the waste gas in the reaction kettle through a delivery pump and transport it to the installation chamber.

[0021] S2. Heat recovery: Store the water in the water storage tank through the coiled pipe and thereby adsorb the heat in the installation chamber.

[0022] S3. Waste gas treatment: Transport the waste gas inside the installation chamber to the purification tank through the connecting pipe and the telescopic pipe, and then dissolve the substances soluble in water in the waste gas through the aqueous solution inside the purification tank. After that, the waste gas will sequentially pass through the drying layer and the activated carbon adsorption layer, and finally be discharged through the discharge pipe.

[0023] S4. Water source replacement: Close the electric control valve. At this time, the purified gas will push the water inside the coiled pipe to flow.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. In the present invention, the waste gas in the reaction kettle is extracted through a delivery pump and transported to the installation chamber. When the waste gas enters the installation chamber, by arranging the mutually staggered first inclined plate and the second inclined plate, the flow time of the waste gas inside the installation chamber is prolonged, so that the heat can be better transported to the installation chamber. After that, the water in the water storage tank is stored through the coiled pipe, and thereby the heat in the installation chamber is adsorbed.

[0026] 2. In the present invention, the waste gas inside the installation chamber is transported to the purification tank through the connecting pipe and the telescopic pipe, and then the substances soluble in water in the waste gas are dissolved through the aqueous solution inside the purification tank. After that, the waste gas will pass through the drying layer, thereby drying the waste gas and preventing the water vapor in the waste gas from affecting the filtering performance of the activated carbon adsorption layer. Then the waste gas continues to rise and passes through the activated carbon adsorption layer. At this time, the activated carbon adsorption layer will filter the waste gas, so as to achieve the purpose of purifying the waste gas.

[0027] 3. In the present invention, by closing the electric control valve, at this time, the purified gas will, under the action of the delivery pump and the delivery pipe, push the water inside the coiled pipe to flow, so as to transport the heated water to the upper chamber. At this time, the electric control valve is reopened, and then the water in the lower chamber re-enters the coiled pipe to continue absorbing the waste heat. Description of the Drawings
