Continuous crystallizer
working principleCrystallization is the process of precipitating solids from a solution, and the supersaturation of the solution is the main driving force for industrial crystallization.The continuous crystallizer achieves a continuous and stable crystallization process through a forced circulat
Low-temperature evaporator
Product OverviewLow temperature evaporator is a fully automatic vacuum evaporator that utilizes advanced heat pump technology, designed specifically for industrial wastewater reduction and resource utilization. The equipment operates under high vacuum (approximately -96KPa), with a stable evapor
falling film evaporator
The evaporated liquid is transported to the top of the heater through a circulation pump and evenly distributed to each heat exchange tube through a dedicated film distributor. The material flows downwards in a film like manner along the inner wall of the pipe under the action of gravity, evaporating while flowing. The generated secondary steam enters the separation chamber together with the concentrated liquid, and is filtered by the high-efficiency demister at the top to remove entrained bubbles, droplets, and impurities, providing a high-quality and clean secondary heat source for subsequent heat recovery.
multiple-effect evaporator
Multi effect evaporator is an energy-saving evaporation device that realizes the cascade utilization of thermal energy. The core principle is to introduce the secondary steam generated by the evaporation of the previous effect material into the subsequent effect as a heating source. Through this series operation, the system can recover and utilize the latent heat of secondary steam multiple times, thereby significantly reducing the consumption of steam. In theory, the more efficiency there is, the higher the reuse rate of steam, and the more significant the energy-saving effect.
MVR Evaporator
Evaporator is an efficient and energy-saving evaporation and concentration equipment. The core principle is to adiabatically compress the secondary steam generated by the evaporation system through a steam mechanical compressor, increasing its pressure and saturation temperature. The heated steam is reintroduced into the evaporator heating chamber as a heat source to heat the material, causing it to continuously boil and evaporate.

PROFESSION
pharmaceutical wastewater

The organic wastewater generated during the pharmaceutical process is the main source of pollution, accounting for 2% of the national wastewater discharge.

industrial wastewater

Industrial production water, rinse water, deep washing, and other industrial production processes all generate a large amount of wastewater containing various high concentration pollutants. These wastewater need to undergo internal system treatment before being discharged into public sewage systems or rivers. In lakes and oceans.

petrochemical wastewater

The treatment of petrochemical wastewater has always been a global challenge due to its high concentration, difficulty in dissolution, and significant environmental pollution.

high-salt wastewater

High salt wastewater is mainly divided into high salt organic wastewater and high salt inorganic wastewater. High salt wastewater is generated through a wide range of pathways, and the amount of water is increasing year by year. The discharge of high salt wastewater has a huge impact on the environment, so the pollutants in the wastewater must be removed first before discharge

landfill leachate

Garbage leachate causes oxygen deficiency in surface water bodies, deteriorates water quality, and seriously affects drinking water sources. With the increase of storage years, fresh garbage gradually turns into stale garbage, with complex components and reduced biodegradability, making the treatment very difficult.

fermentation industry

Evaporation equipment is widely used in industrial industries such as chemical, pharmaceutical, and food fermentation. There are various types of evaporators, and their classification methods are also diverse. According to the purpose of use, there are evaporative concentration type and evaporative crystallization type; According to the material flow method, it can be divided into rising film type, falling film type, lifting film type, etc. Although the classification methods are different, their common feature is the transfer of heat to the material to evaporate the solution.

Emulsified wastewater

The domestic mechanical processing industry extensively uses emulsions, and their waste liquid has always been a serious environmental pollution problem that has not been effectively solved. In the past, domestic research on the treatment of waste liquids mainly focused on oil-based emulsions, with a focus on addressing COD and oil discharge pollution issues.

high ammonia nitrogen wastewater

In the fertilizer industry, rare earth and many other chemical production processes, a certain amount of ammonium chloride wastewater is generated. Due to the high content of ammonia nitrogen and the presence of chloride ions in ammonium chloride wastewater, direct discharge will cause certain pollution to the water body. As the discharge volume continues to increase, the degree of pollution also increases, and the treatment of ammonium chloride wastewater is a major challenge. The use of evaporation concentration process results in high steam consumption and severe corrosion of the material by ammonium chloride solution.

new energy

New energy wastewater (lithium battery/photovoltaic) has the characteristics of high salt content, high toxicity, heavy metal/fluoride content, difficult biochemistry, strong corrosion, and easy scaling. Conventional processes cannot stably meet standards and achieve zero emissions. Jiaqiang Machinery's titanium MVR+forced circulation crystallization complete set of equipment fully matches the needs of new energy wastewater treatment in terms of corrosion resistance, scale prevention, energy conservation, and resource utilization, and is a mainstream mature solution in the industry.

new material

Wastewater from the new materials industry generally has characteristics such as high salt content, high COD, heavy metal and fluoride content, complex water composition, strong corrosiveness, and extremely poor biodegradability. Conventional biochemical processes are difficult to degrade and meet standards.

food industry

The overall organic content of wastewater in the food industry is high, rich in biodegradable substances such as starch, sugars, proteins, and oils. The COD and BOD concentrations are high, and the water is prone to decay and odor. At the same time, the water contains a high amount of suspended impurities, fruit pulp residue, and production debris, which can easily deposit and block pipeline facilities;
