Description

Technical Field

[0001] The utility model relates to the technical field of ethylene glycol coolant recovery, and specifically relates to an ethylene glycol coolant recovery device. Background Technique

[0002] An ethylene glycol coolant recovery device is a device used to recover ethylene glycol in wastewater. This device is mainly used in fields such as chemical industry, medicine, and electronics because it has a wide range of applications in these fields. As an important organic chemical, a large amount of ethylene glycol-containing wastewater will be generated during the production process. If not treated, these wastewaters will not only cause environmental pollution but also waste resources. Therefore, the application of ethylene glycol recovery devices is particularly important;

[0003] The working principle of an ethylene glycol recovery device is to treat the ethylene glycol-containing wastewater through a series of physical and chemical processes to meet the requirements for recovering ethylene glycol. This process usually includes three parts: rough separation, fine separation, and recovery. In the rough separation part, mainly solid particles and other impurities in the wastewater are removed; in the fine separation part, ethylene glycol is further separated and purified; finally, in the recovery part, the purified ethylene glycol is recovered and utilized through physical methods such as condensation and evaporation.

[0004] In addition, there is also a device for recovering ethylene glycol from waste automotive antifreeze. This device includes components such as an antifreeze storage tank, an alkali reactor, an acid reactor, a pressurization and heating assembly, a flash tank, and a reboiler. Through a series of chemical reactions and physical processes, automatic control is achieved, saving manpower and improving production efficiency.

[0005] There is also a method for purifying, recovering, and treating the refrigerant ethylene glycol. By connecting a precision filter, a cation exchange resin column, and an anion exchange resin column to the original refrigerant pipeline of the condensation system, the impurities in ethylene glycol are treated to achieve the unity of waste liquid treatment and resource utilization.

[0006] For conventional equipment used to recover ethylene glycol in wastewater, the filtration equipment is generally installed using an external connection and a relatively simple fixing frame. Although this usage method can relatively limit the cost, it makes the filtration structure vulnerable to damage or even leakage caused by external factors.

[0007] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an ethylene glycol coolant recovery device is proposed. Content of the Utility Model

[0008] The purpose of the utility model is to provide an ethylene glycol coolant recovery device to solve the problems raised in the above background technique.

[0009] To achieve the above object, the present utility model provides the following technical solutions: An ethylene glycol coolant recovery device, comprising a stable ring frame and a first protective chamber. A storage tank group is vertically installed in the middle of the stable ring frame, and a diversion pipe is horizontally connected to one end of the bottom of the storage tank group. The first protective chamber is connected to one end of the diversion pipe away from the storage tank group, and the other side of the end of the diversion pipe away from the storage tank group is connected to a second protective chamber. Moreover, filtering components are installed inside both the first protective chamber and the second protective chamber. The first protective chamber includes a main chamber body, a connection valve, an external connection valve, and a liquid discharge pump. The connection valve is installed at the lower end of one side of the main chamber body close to the diversion pipe, the external connection valve is installed at the upper end of the other side of the main chamber body away from the connection valve, and the liquid discharge pump is installed at the lower end of the other side of the main chamber body away from the connection valve.

[0010] Further, the storage tank group includes a main tank body, an upper cover, and a charging valve. The upper cover is installed on the top of the main tank body, and the charging valve is installed in the middle of the top of the upper cover.

[0011] Further, the storage tank group further includes a lower cover and a centrifugal pump. The lower cover is installed at the bottom of the main tank body, and the centrifugal pump is installed at the center of the bottom of the lower cover.

[0012] Further, both the upper cover and the lower cover are connected to the main tank body by flange structures, and one end of the centrifugal pump away from the lower cover is connected to the diversion pipe.

[0013] Further, one end of the connection valve away from the main chamber body is connected to the diversion pipe, and the diversion pipe is connected to the storage tank group, the first protective chamber, and the second protective chamber through a quick-connection joint structure.

[0014] Further, the second protective chamber and the first protective chamber have the same structure, and the first protective chamber and the second protective chamber are arranged in parallel.

[0015] Further, the filtering component includes a device frame, fixing piles, precision filters, and connecting pipes. The fixing piles are arranged at equal intervals on the side of the device frame, the precision filters are arranged at equal intervals in the middle of the device frame, and connecting pipes are installed at both the upper and lower ends of the precision filters.

[0016] Further, the connecting pipes are connected end to end in sequence at the upper and lower ends through the connecting pipes. The device frames are symmetrically installed at the upper and lower ends of the precision filters, and the fixing piles are vertically installed on the left and right sides of the device frame. The connection valve and the external connection valve are respectively communicated with the precision filters at the starting end and the ending section through the connecting pipes.

[0017] The present utility model provides an ethylene glycol coolant recovery device, which has the following beneficial effects:

[0018] 1. The utility model is provided with a first protective compartment and a second protective compartment having the same structure. The structural setting of the main compartment can, on the one hand, provide effective structural protection for the internal filter assembly to ensure that the filter assembly can operate stably and safely and avoid structural damage to the filter assembly caused by external factors. On the other hand, when the filter assembly has a structural leakage, the main compartment can play an effective receiving role by utilizing its structure, which can prevent the leaked refrigerant from scattering and causing environmental pollution and facilitate centralized recovery. The structural setting of the drainage pump can be used to quickly discharge the refrigerant in the main compartment, or use a pipeline to connect with the storage tank group, so as to directly reflux, so as to facilitate subsequent treatment after maintenance.

[0019] 2. The utility model connects the upper cover and the lower cover to the main cabin body by adopting flange structure, which can ensure the firmness and sealing of the structural connection on the one hand, and on the other hand, when the entire storage tank group stores refrigerant for a long time, the internal impurities are deposited on the inner wall, affecting the normal use, and the structure can be used for rapid disassembly so that the operating personnel can perform maintenance on the inside thereof. The two groups of filter components are connected by the structure of the shunt pipe, which can effectively improve the efficiency of refrigerant treatment inside the storage tank group. At the same time, a plurality of precision filters are arranged and installed by the device frame. Under the structural connection of the connecting pipe, the refrigerant can be filtered and impurities removed to the greatest extent, so as to facilitate the subsequent device to process the refrigerant, so as to ensure that the ethylene glycol refrigerant can be quickly recovered and processed and reused.

The second protective cabin 5 has the same structure as the first protective cabin 4, and the first protective cabin 4 and the second protective cabin 5 are arranged parallel to each other. The structural setting of the main cabin body 401 can, on the one hand, provide effective structural protection for the internal filter assembly 6 to ensure that the filter assembly 6 can operate stably and safely and avoid structural damage to the filter assembly 6 caused by external factors. On the other hand, when the filter assembly 6 has structural leakage, the main cabin body 401 can play an effective receiving role by utilizing its structure.

[0026] like Figures 1 to 3As shown in the figure, the storage tank group 2 includes a main tank body 201, an upper cover 202 and a filling valve 203. The upper cover 202 is installed at the top of the main tank body 201, and the filling valve 203 is installed in the middle of the top of the upper cover 202. The storage tank group 2 also includes a lower cover 204 and a centrifugal pump 205.
