Description

Technical Field

[0001] This utility model relates to the field of n-butyl acetate production technology, specifically to a VOCs treatment device for n-butyl acetate production. Background Technology

[0002] During the production of n-butyl acetate, due to its volatility and potential equipment leaks, butyl acetate waste gas is generated. Existing treatment methods for this waste gas mainly use activated carbon adsorption. However, the use of activated carbon adsorption alone requires a high frequency of activated carbon replacement, and the subsequent desorption treatment also requires many steps, resulting in poor treatment efficiency and insufficient resource utilization. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of the aforementioned background technology by providing a VOCs treatment device for the production of n-butyl acetate that ensures treatment effect and efficiency while saving resources.

[0004] To achieve the above objectives, this utility model provides a VOCs treatment device for the production of n-butyl acetate, which adopts the following technical solution:

[0005] A VOCs treatment device for the production of n-butyl acetate includes a collection structure connected to a condensing device via a connecting pipe. The condensing device is connected to a treatment tower structure. The treatment tower structure is equipped with a spray structure, and an adsorption structure is located above the spray structure. A heat exchange chamber is provided on the connecting pipe, and the heat exchange chamber is connected to an inlet pipe and an outlet pipe. The outlet pipe is connected to a steam generator, which is connected to a desorption structure. The desorption structure is connected to a burner structure.

[0006] A further improvement of this utility model of a VOCs treatment device for the production of n-butyl acetate is that a thermometer is provided on the connecting pipe, and the thermometer is located on the side of the heat exchange chamber away from the condensing equipment.

[0007] A further improvement of this utility model of a VOCs treatment device for the production of n-butyl acetate is that the water inlet pipe is connected to an external water source, the steam generator is also connected to an external water source, and the condensing equipment is connected to a drain pipe.

[0008] A further improvement of this utility model of a VOCs treatment device for the production of n-butyl acetate is that the outlet pipe is also connected to a storage tank, and the storage tank is connected to a spray liquid production pool.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] This invention recovers and utilizes butyl acetate by condensing high-concentration n-butyl acetate waste gas. The condensed waste gas then enters a treatment tower structure for alkaline spraying and activated carbon adsorption, further absorbing and treating the butyl acetate in the waste gas, thus ensuring treatment effect and efficiency.

[0011] This invention utilizes cold water heat exchange combined with stable monitoring to prevent excessively high-temperature exhaust gas from entering the condensing equipment and affecting its operation. At the same time, the water after heat exchange can also be used to generate steam for the desorption of activated carbon. The desorbed exhaust gas then enters the combustion structure for combustion, thereby improving energy utilization and saving resources. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0019] like Figure 1 As shown, a VOCs treatment device for the production of n-butyl acetate includes a collection structure 1 for collecting butyl acetate waste gas generated during the production process. The collection structure is connected to a condensation device 3 via a connecting pipe 2. The condensation device is existing equipment used to liquefy the butyl acetate in the waste gas. The condensation device is connected to a treatment tower structure 9, which contains a spray structure 11 for spraying alkaline solution. Above the spray structure is an adsorption structure 12, which may be an activated carbon adsorption structure. A heat exchange chamber 4 is provided on the connecting pipe, connected to an inlet water pipe 5 and an outlet water pipe 6. The outlet water pipe is connected to a steam generator 7, which is connected to a desorption structure 8, which is connected to a burner structure.

[0020] Furthermore, a thermometer is installed on the connecting pipe, positioned on the side of the heat exchange chamber away from the condensing equipment. Control valves are installed on both the outlet and inlet water pipes.

[0021] Furthermore, the inlet pipe is connected to an external water source, the steam generator is also connected to an external water source, and the condensation equipment is connected to a drain pipe 10. The outlet pipe is also connected to a storage tank, which is connected to the spray liquid production pool.

[0022] The working principle of this invention is as follows: the collected butyl acetate waste gas enters the condensation equipment, where the butyl acetate gas condenses into a liquid and is discharged through the drain pipe for recycling. The condensed waste gas then enters the treatment tower, where it is first sprayed and then adsorbed to ensure the treatment effect. The activated carbon used for adsorption is placed in the desorption structure and heated for desorption. The desorbed gas then enters the burner structure for combustion. At the same time, to ensure the normal and continuous operation of the condensation equipment, cold water can be used for heat exchange and cooling based on the monitored temperature. The water after heat exchange can be used for steam production or for spray liquid manufacturing, thus improving the efficient use of energy.

In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
