DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The following will specifically describe the preferred embodiments of the present utility model with reference to the drawings. The drawings form a part of this application and are used together with the embodiments of the present utility model to explain the principle of the present utility model, and are not used to limit the scope of the present utility model.

[0031] A box-type waste liquid treatment device in this embodiment relates to the technical field of environmental protection treatment of industrial waste liquid. A compressed air drying unit 320 and a heating unit 330 are arranged in a drying box body 100, which can remove moisture in the air while raising the temperature, inhibit heat dissipation, and improve the utilization efficiency of air thermal energy. The heating unit 330 is provided with high-temperature filler 332. When air flows through the filler 332, the filler 332 can heat the air, thereby improving the conduction efficiency of heating.

[0032] Please refer to Figures 1 to 4 , a box-type waste liquid treatment device in this embodiment includes a drying box body 100, an evaporation assembly 200, and a dehumidification assembly 300. Among them, a relatively isolated evaporation chamber 110 and a dehumidification chamber 120 are formed in the drying box body 100, which can separate the evaporation process of the waste liquid and the water vapor separation process to avoid mutual interference between the two. At the same time, the drying box body 100 provides a closed environment, limiting the waste liquid treatment process in the drying box body 100, thereby avoiding the overflow of waste gas.

[0033] The evaporation assembly 200 includes an air flow channel 210 and an evaporation drawer 220 for storing waste liquid. The air flow channel 210 is arranged in the evaporation chamber 110. A plurality of evaporation drawers 220 are movably inserted into the drying box body 100. The air flow channel 210 intersects with the evaporation drawer 220. The air flow channel 210 is relatively tortuous, which can extend the path of the air flow, increase the contact time between the air flow and the waste liquid, and promote the evaporation of the waste liquid.

[0034] The dehumidification assembly 300 is arranged in the dehumidification chamber 120. The dehumidification assembly 300 includes a dehumidification pipeline 310 and a compressed air drying unit 320 and a heating unit 330 arranged on the dehumidification pipeline 310. The dehumidification pipeline 310 can sequentially input the humid and hot air into the compressed air drying unit 320 and the heating unit 330 to complete the heating and dehumidification of the air. Both ends of the dehumidification pipeline 310 are communicated with both ends of the air flow channel 210. The dehumidification pipeline 310 can draw the humid and hot air from the evaporation chamber 110 to flow through the compressed air drying unit 320 and the heating unit 330 and then return to the evaporation chamber 110 to form an evaporation cycle, continuously evaporating the moisture in the waste liquid and promoting the crystallization of substances in the waste liquid.

[0035] The heating unit 330 includes a heating housing 331 and high-temperature filler 332. The filler 332 is filled in the heating housing 331. The heating housing 331 can keep the filler 332 warm and inhibit heat dissipation. The high-temperature filler 332 can heat the passing air, raise the temperature of the air, and further promote the evaporation process of the waste liquid.

[0036] It should be noted that an air compressor 321 is provided in the compressed air drying unit 320, which can pressurize the air, increase the temperature and pressure of the air, promote the high-speed flow of the air, and provide power for the air to flow in the air flow channel 210.

[0037] In some embodiments, referring to Figures 1 to 3 , the dehumidification component 300 further includes a heating unit 340. The heating unit 340 includes a plurality of heating rods 341. The heating rods 341 are electric heating rods 341, and the electric heating rods 341 are directly inserted into the heating housing 331 to heat the packing 332 and keep the packing 332 in a high-temperature state. When the air passes through the gaps between the packings 332, the packings 332 can heat the air, increase the temperature of the air entering the evaporation chamber 110, and promote the evaporation of the waste liquid.

[0038] In the specific implementation process, the packing 332 is a metal oxide or nitride packing 332. Specifically, the packing 332 is alumina, magnesia, zinc oxide, aluminum nitride, boron nitride, silicon carbide, etc. The packings 332 are spaced apart from each other to form a flow gap, and the air can pass through the flow gap.

[0039] In some embodiments, referring to Figure 2 and Figure 3 , the heating housing 331 includes an air inlet 331a and an air outlet 331b communicating with the dehumidification pipeline 310 and an openable and closable pressure relief port 331c. The air dehumidified by the compressed air drying unit 320 enters the heating housing 331 from the air inlet 331a, is heated by the packing 332 in the heating housing 331, and then is discharged from the air outlet 331b into the evaporation chamber 110. The pressure relief port 331c is communicated with the outside through a pipeline. When the gas pressure in the heating housing 331 is too high due to temperature rise, the excess gas can be discharged from the pressure relief port 331c to achieve the purpose of pressure relief.

[0040] In some embodiments, referring to Figure 1 , the compressed air drying unit 320 includes a compressor 321 and an adsorption dryer 322. Both the compressor 321 and the adsorption dryer 322 are communicated with the dehumidification pipeline 310. The compressor 321 can heat and pressurize the air, increase the air temperature and pressure, and make the moisture in the air easier to evaporate and separate. The adsorption dryer 322 absorbs the moisture in the air through the adsorption material, further reduces the air humidity, and realizes efficient air drying. The combined action of the compressor 321 and the adsorption dryer 322 ensures that the air humidity is stably maintained at a low level and improves the overall effect of the dehumidification component 300.

[0041] In the specific implementation process, the adsorption dryer 322 is internally provided with a solid moisture absorbent that can desorb moisture. The main adsorbents used are silica gel, alumina gel, and molecular sieve. These adsorbents have a large number of pores, so they have a large specific surface area. When the vapor partial pressure on the surface of the adsorption material is less than the vapor surface partial pressure in the air, the moisture in the compressed air is adsorbed. However, when the adsorbent adsorbs enough moisture and becomes saturated, desorption regeneration must be carried out in order to adsorb again so that the dryer can work continuously. The adsorption dryer 322 has two towers. One tower is under working pressure to adsorb and dry the air, and the other tower is under normal pressure for desorption regeneration. Thus, the two towers carry out drying and regeneration under the control of the electric controller and work alternately to continuously provide dry compressed air.

[0042] In some embodiments, referring to Figure 1 and Figure 4 , at least one partition 221 is provided inside the evaporation drawer 220. The partition 221 is fixedly connected to the evaporation drawer 220, and the partition 221 can separate the inner cavity of the evaporation drawer 220. The fixed connection between the partition 221 and the evaporation drawer 220 can enhance the overall structural stability of the evaporation drawer 220 and prevent structural deformation or damage caused by air flow impact. The partition 221 can divide the inner cavity of the evaporation drawer 220 into several independent regions, preventing the waste liquid from fluctuating violently as the air flows and overflowing from the evaporation drawer 220.

[0043] In a further embodiment, the partition 221 is arranged perpendicular to the flow direction of the air flow channel 210. The vertically arranged partition 221 will force the air flow to generate disturbances during the flow process, increasing the contact opportunity between the air flow and the adsorption material and improving the adsorption efficiency. When the air flow encounters the partition 221 perpendicular to the flow direction, it will be forced to disperse and redirect, generating disturbances. The disturbances can accelerate the air flow on the surface of the waste liquid and promote the evaporation of the waste liquid.

[0044] The partition 221 is provided with communication holes 222. The communication holes 222 can communicate the chambers separated by the partition 221 to realize the liquid flow between the chambers, so that the liquid levels in the chambers are kept at the same height, avoiding inconsistent evaporation amounts in the chambers.

[0045] In some embodiments, referring to Figure 1 , an infusion tube 130 is provided in the evaporation chamber 110 opposite to the evaporation drawer 220. The infusion tube 130 can input the waste water from the outside into the evaporation drawer 220. The waste water is introduced into the evaporation drawer 220 through the infusion tube 130. During the evaporation process, the moisture in the waste water is removed, and the remaining solid substances can be further processed or utilized. The infusion tube 130 can intermittently transport the waste liquid into the evaporation drawer 220 to promote the crystallization of the waste liquid.

[0046] As described above, it is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the present utility model.
