Long-term consumption of water containing saline solution can cause various damages to the lymphatic system.

[0003] Currently, most saline wastewater is treated by membrane filtration, but the commonly used methods for treating the large amounts of concentrated liquid produced after treatment have many problems:

[0005] Secondly, traditional heating, evaporation and concentration methods are extremely energy-intensive, resulting in high processing costs, as well as expensive equipment and maintenance costs.

[0006] Third, using catalytic reducing agents for chemical reactions is problematic because the structure of concentrated salt solution is stable, the catalytic reduction reaction is extremely slow, making it difficult to apply on a large scale in practice. The treatment effect is poor, and the concentrated salt solution cannot be completely decomposed during the catalytic reduction process, which may also produce other concentrated solutions.

[0007] Therefore, there is an urgent need for a high-efficiency, energy-saving, and low-cost brine concentrate treatment system. Utility Model Content

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present utility model. Obviously, the embodiments described in this utility model are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0036] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0037] Example 1: The specific structure of this utility model is as follows:

[0038] Please refer to the appendix. Figure 1-6 The present invention discloses a zero-emission natural evaporation system for concentrated liquid, comprising a liquid storage tank 1, a water pump 7, and a modular evaporation module 100.

[0039] The storage tank 1 has an inlet port 6 and a storage chamber; the storage tank 1 has an opening at the top, and its inlet port 6 is connected to a replenishment pipeline. When the storage tank 1 is below the warning water level, it is automatically replenished through an external concentrated liquid replenishment system. Specifically, the inlet port 6 is connected to the salt concentrate generation equipment of the fireworks and firecrackers company via a pipeline to receive the concentrated liquid. The storage tank 1 is made of corrosion-resistant stainless steel, which can effectively prevent the concentrated liquid from corroding the storage tank.

[0040] A water pump 7 is fixed to the storage tank 1. The inlet of the water pump 7 is connected to an inlet pipe, the inlet end of which extends to a region near the bottom of the storage chamber. After the water pump 7 starts, it transports the concentrated liquid in the storage tank 1 to the spray pipe 4 of the modular evaporation module 100. Specifically, the water pump 7 is fixed to the outside of the storage tank 1 with bolts. The inlet end of the inlet pipe extends to a position 1-5 cm from the bottom of the storage chamber to ensure sufficient extraction of the concentrated liquid. The power of the water pump 7 is selected appropriately based on the system scale and the concentrated liquid processing capacity.

[0041] The modular evaporation module 100 includes at least one set, comprising a frame 3 that can be mounted on the liquid storage tank 1, an evaporation filter cloth assembly 2 disposed within the frame 3, and a spray pipe 4 mounted on the frame 3 and positioned directly above the evaporation filter cloth assembly 2. The spray nozzle 8 of the spray pipe 4 faces the evaporation filter cloth assembly 2, and the spray pipe 4 is connected to the outlet of the water pump 7 via a pipe. The evaporation filter cloth assembly 2 consists of 10-50 pieces of polypropylene fiber filter cloth vertically fixed at intervals of 5-10 cm.

[0042] The evaporation filter cloth group 2 consists of multiple filter cloths arranged vertically at certain intervals and fixed to the frame 3. Each group of filter cloths has multiple pieces, and the filter cloths are capable of absorbing concentrated liquid. The nozzles 8 of the spray pipe 4 spray the concentrated liquid downwards, and the concentrated liquid falls onto the filter cloth. The concentrated liquid is absorbed by the filter cloth and seeps downwards. Because the filter cloth can absorb the concentrated liquid very well, and with the combined influence of sunlight and wind, the concentrated liquid seeps onto the surface of the filter cloth. The water in the concentrated liquid evaporates naturally during the seepage process. Evaporation is affected by temperature, humidity, wind speed, as well as the material and surface area of ​​the filter cloth.

[0043] The lower end of the filter cloth is provided with a gravity strip 9 for naturally straightening the filter cloth. The gravity strip 9 can be fixed to the frame with screws or not.

[0044] When there are multiple modular evaporation modules 100, they are assembled into a linear array structure by the frame 3. Multiple modular evaporation modules 100 can accelerate the evaporation efficiency of the concentrated liquid. These modules are placed in the storage tank 1 and connected to water pumps 7 via pipelines. When the number of water pumps 7 is insufficient, the number of pumps 7 is increased to meet the requirements of the concentrated liquid circulation pipeline layout.

[0045] An auxiliary fan 5 is also installed on the top of the frame 3. The auxiliary fan increases the effect of natural evaporation on cloudy days or when the temperature is low, and the concentrated liquid is finally concentrated through several cycles of evaporation.

[0046] The frame 3 is a steel structure frame, and the steel structure frame is stable.

[0047] The top of the frame 3 is provided with a removable cover plate 10, which is inclined. Since the zero-emission natural evaporation system for concentrated liquid concentration of this utility model is mostly placed in open areas, the cover plate 10 is added to the frame 3 to prevent rain when it rains.

[0048] Specifically, when the system is running, the concentrated salt solution enters the storage chamber of the storage tank 1 through the inlet port 6. The water pump 7 is then activated, pumping the concentrated solution to the spray pipe 4, where it is sprayed onto the evaporation filter cloth assembly 2 via nozzles 8. Evaporation begins under the influence of sunlight and natural wind. In cloudy or windy conditions, the auxiliary fan 5 automatically starts to accelerate airflow and promote evaporation. Any incompletely evaporated concentrated solution drips back into the storage tank 1 and is pumped back into the tank by the water pump 7 for further processing. After multiple cycles, the concentrated solution is finally concentrated and crystallized, achieving zero discharge.

[0049] In summary, the zero-emission natural evaporation system for concentrated liquid concentration of this invention is significantly energy-efficient: this invention uses the natural forces of sunlight and airflow to evaporate concentrated liquid, saving more than 95% of energy compared to conventional evaporation, thus reducing energy costs.

[0050] The zero-emission natural evaporation system for concentrated liquid concentration of this utility model reduces costs: the modular design makes the production and installation of the evaporation system more convenient, reducing production costs; at the same time, due to the significant reduction in energy consumption and the optimization of the structure, the maintenance costs of the equipment are also significantly reduced.

[0051] The zero-emission natural evaporation system for concentrated liquid concentration of this utility model is easy to clean: after the concentrated liquid evaporates and crystallizes, the residue is concentrated in the evaporation filter cloth and the storage tank, which is easy to clean and reduces the difficulty and workload of manual cleaning.

[0052] The zero-emission natural evaporation system for concentrated liquid concentration of this utility model is simple to operate: the system operation mainly relies on natural conditions and simple equipment control, without the need for complicated operation procedures, and is easy to master and manage; moreover, the equipment has a compact structure, high stability, and convenient maintenance.

[0053] This invention provides a zero-emission natural evaporation system for concentrated liquid treatment, ensuring thorough liquid treatment: through multiple cyclic evaporation cycles, the system can fully concentrate the salt and other salts in the concentrated liquid, achieving true zero emissions and effectively solving the environmental pollution problem caused by concentrated salt liquid.

[0054] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural or procedural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
