Description

Technical Field

[0001] This application relates to the field of waste gas treatment technology, and specifically discloses a waste gas treatment device for chemical safety management. Background Technology

[0002] Waste gas treatment equipment is used to treat waste gases generated during industrial production processes. Its purpose is to reduce pollutant emissions and protect the environment and human health. Waste gases contain a wide variety of pollutants, including volatile organic compounds (VOCs), particulate matter, sulfur dioxide, and nitrogen oxides. Different waste gas treatment equipment has its own treatment principles and effects for different types and concentrations of pollutants. After a series of treatments, the waste gases meet emission standards, which helps reduce damage to nature and the atmospheric environment.

[0003] However, existing waste gas treatment equipment mainly consists of a treatment tower, which includes a shell, a spray structure inside the shell, an air duct connecting to the bottom of the shell, and an outlet pipe installed at the top of the shell. The existing spray structure consists of a disc-shaped spray pipe and a spray head integrally formed at the bottom of the spray pipe. Because the spray pipe and spray head are integrally formed, during maintenance, if maintenance personnel find any damage to the spray pipe or spray head, both need to be completely replaced, increasing maintenance costs.

[0004] Therefore, the inventors have provided a waste gas treatment device for chemical safety management to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing spray pipes and spray heads are integrally molded, and if maintenance personnel find any damage to the spray pipe or spray head during the maintenance process, the spray pipe and spray head need to be completely replaced, which increases maintenance costs.

[0006] To achieve the above objectives, the basic solution of this utility model provides a waste gas treatment device for chemical safety management, including a shell, a filter structure for filtering waste gas and a spray structure for spraying purification liquid arranged sequentially from top to bottom inside the shell, a ventilation pipe for introducing waste gas into the shell on one side, a discharge pipe for discharging purification liquid at the bottom of the shell, and a maintenance door for inspecting the device on one side of the shell. The spray structure includes several water guide rings with progressively decreasing diameters, water guide chambers respectively opened in the water guide rings, several spray pipes detachably connected to the bottom of the water guide rings and arranged vertically, several spray heads detachably connected to the spray pipes, and a liquid inlet pipe located on one side of the shell and communicating with the water guide chambers. All spray pipes are communicating with the water guide chambers, all water guide rings are located in the same plane, the outermost water guide ring is detachably connected to the inner wall of the shell, and there are detachable connection structures between adjacent water guide rings. A connecting water pipe for communicating with the water guide chambers can also be detachably connected between adjacent water guide rings.

[0007] The principle and effect of this basic scheme are as follows:

[0008] 1. Compared with the prior art, the spray pipe of this utility model is set vertically, and several spray heads are installed on the spray pipe. The purification liquid is continuously sprayed within the height range to maintain a certain concentration. The purification effect will not decrease as the height decreases, so that the waste gas and purification liquid in the shell can fully react.

[0009] 2. Compared with the prior art, this utility model is equipped with multiple sets of water guide rings, spray pipes and spray heads. The adjacent water guide rings, the water guide rings and the spray pipes, and the spray pipes and spray heads are all connected by a detachable connection. If a single water guide ring, a single spray pipe or spray head is blocked or damaged, it will not affect the overall use of the spray structure. When the waste gas treatment equipment is inspected regularly, the maintenance personnel can open the maintenance door to enter the equipment and replace the blocked or damaged water guide rings, spray pipes or spray heads independently. This is convenient and quick. It solves the problem that the spray pipes and spray heads are integrally formed. During the maintenance process, if the maintenance personnel find that there is damage to a certain part of the spray pipe or the spray head, the spray pipe or spray head needs to be completely replaced, which increases the maintenance cost.

[0010] Furthermore, the connection structure includes connecting blocks respectively fixed to adjacent water guide rings and connecting rods whose two ends are respectively bolted to adjacent connecting blocks.

[0011] Furthermore, the filtration structure includes a fixed plate and several filter tubes. The fixed plate is detachably connected to the housing and divides the housing into two chambers: a spray chamber and a filtration chamber. Several filter tubes are detachably connected to the fixed plate, connecting the spray chamber and the filtration chamber. Each filter tube has several filter grooves filled with activated carbon adsorption plates. The detachable connection of the filter tubes to the fixed plate facilitates cleaning and replacement of individual filter tubes. The activated carbon adsorption plates in the filter grooves adsorb harmful substances in the exhaust gas, ensuring that the exhaust gas meets emission standards before being discharged from the housing.

[0012] Furthermore, the filter tubes are arranged circumferentially on the fixed plate. The circumferentially arranged filter tubes can distribute the filtration area more evenly, so that the exhaust gas that has reacted with the purification liquid can come into more uniform contact with the filter medium when passing through the filter tubes, thereby improving filtration efficiency and filtration effect.

[0013] Furthermore, the spray pipe is detachably connected to a plurality of spray heads in a circumferential array, with the spray heads on adjacent spray pipes arranged vertically at equal intervals. The equal-interval arrangement of the spray heads on adjacent spray pipes ensures a consistent concentration of the purified liquid within the length of the spray pipe, allowing for a more complete reaction between the waste gas and the purified liquid. Furthermore, the spray heads and spray pipes are connected by a threaded connection. This detachable threaded connection facilitates the replacement of individual spray heads.

[0018] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0019] The reference numerals in the accompanying drawings include: housing 1, vent pipe 2, liquid inlet pipe 3, water guide ring 4, spray pipe 5, spray head 6, filter pipe 7, water guide chamber 8, and discharge pipe 9.

[0020] A waste gas treatment device for chemical safety management, implementing, for example Figure 1 , Figure 2 and Figure 3 As shown: It includes a housing 1, a filter structure for filtering exhaust gas and a spray structure for spraying purification liquid installed inside the housing 1 from top to bottom, a ventilation pipe 2 for introducing exhaust gas into the housing 1 installed on the right side of the housing 1, a discharge pipe 9 for discharging purification liquid installed at the bottom of the housing 1, and a maintenance door for inspecting and repairing the equipment installed on the right side of the housing 1.

[0021] The spray structure includes several water guide rings 4 with successively decreasing diameters, water guide chambers 8 opened in the water guide rings 4, several spray pipes 5 vertically arranged at the bottom of the water guide rings 4, several spray heads 6 installed on the spray pipes 5, and a liquid inlet pipe 3 installed on the left side of the housing 1 and connected to the water guide chambers 8. Specifically, all spray pipes 5 are connected to the water guiding chamber 8, and all water guiding rings 4 are located in the same plane. The outermost water guiding ring 4 is fastened to the inner wall of the shell 1. Several fastening bases with concave tops are fixedly installed on the inner wall of the shell 1. A fastening platform is fixedly installed on the outer side of the water guiding ring 4. The water guiding ring 4 and the shell 1 are connected by pressing the fastening platform into the concave position of the fastening base. A connecting structure is installed between adjacent water guiding rings 4. The connecting structure includes a connecting block fixedly installed on the adjacent water guiding ring 4 and a connecting rod whose two ends are bolted to the adjacent connecting block. A connecting water pipe for communication is also installed between adjacent water guiding rings 4. The connecting water pipe has threaded interfaces at both ends and is threadedly connected to the adjacent water guiding ring 4 through the threaded interfaces.

[0022] Several water guide rings 4 have through holes 1 at the corresponding positions of the spray pipes 5. The inner side of the through hole 1 has an internal thread. The outer wall of the spray pipe 5 port has an external thread that meshes with the internal thread. The spray pipe 5 is installed on the water guide rings 4 by means of threaded connection. The spray pipe 5 has through holes 2 at the corresponding positions of the spray heads 6. The inner side of the through hole 2 has an internal thread. The outer wall of the spray head 6 port has an external thread that meshes with the internal thread. The spray head 6 is installed on the spray pipe 5 by means of threaded connection. The spray heads 6 arranged vertically on adjacent spray pipes 5 are equidistant and aligned. The concentration of the purified liquid is consistent within the length of the spray pipe 5, so that the waste gas and the purified liquid react more fully.

[0023] The filter structure is installed above the spray structure and includes a fixing plate and a filter tube 7 installed inside the housing 1. Specifically, the fixing plate is installed inside the housing 1 by snap-fit ​​and is divided into two chambers inside the housing 1, namely the spray chamber and the filter chamber. The fixing plate has corresponding filter ports at positions relative to the filter tube 7. The fixing plate also has several positioning ring grooves that are coaxial with the filter ports. The bottom of the filter tube 7 is integrally formed with positioning ring plates that can be inserted into the corresponding positioning ring grooves. The positioning ring plates have several first main threaded holes. The fixing plate also has several secondary threaded holes that are circumferentially opened relative to the filter ports and can be aligned with the main threaded holes. The filter tube 7 can be fixed by screwing in bolts. Four filter channels are also opened on the filter tube 7 located above the fixed plate. The top of the filter tube 7 is closed and the bottom is connected to the filter port. The filter channels are filled with activated carbon adsorption plates. The activated carbon adsorption plates remove moisture and harmful substances from the exhaust gas, making the exhaust gas more compliant with emission standards. The filter tube 7 is arranged circumferentially on the fixed plate, so that the filter tube 7 is evenly distributed in the filtration area. This allows the exhaust gas that has reacted with the purification liquid to come into more even contact with the filter medium when passing through the filter tube 7, thereby improving filtration efficiency and filtration effect.

[0024] When this utility model is in use, firstly, the purification liquid is introduced into several water guiding chambers 8 through the liquid inlet pipe 3. The purification liquid is sprayed out from the spray head 6 on the spray pipe 5. Then, the waste gas is introduced into the shell 1 through the ventilation pipe 2. The waste gas reacts fully with the purification liquid in the shell 1 and floats upward. The waste gas is dehydrated and the harmful substances in the waste gas are adsorbed by the dehydration plate and activated carbon adsorption plate in the filter structure. Finally, it is discharged from the top of the shell 1. After all the purified gas is discharged from the top of the shell 1, the purification liquid that has reacted with the waste gas is discharged from the discharge pipe 9 at the bottom of the shell 1.

[0025] In this invention, the spray pipe 5 is vertically downward, and several spray heads 6 are installed on the spray pipe 5. The concentration of the purified liquid sprayed from the spray heads 6 is the same within the length of the spray pipe 5, allowing the waste gas in the housing 1 to react fully with the purified liquid. The water guide ring 4 is detachably connected to the housing 1, which can increase the number of spray pipes 5 and spray heads 6 in the housing 1, thereby increasing the concentration of the purified liquid in the housing 1 and facilitating the full reaction between the waste gas and the purified liquid. Of course, in other embodiments, multiple water guide rings 4 with different diameters can also be added. In this invention, both the spray pipe 5 and the spray head 6 are detachably connected. If a single spray pipe 5 or spray head 6 is blocked, it will not affect the use of the spray structure. When the waste gas treatment equipment is inspected periodically, maintenance personnel can access the equipment through the maintenance door and only need to replace a single spray pipe 5, without replacing the entire spray structure, thus saving maintenance costs.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
