On August 12, 2016, Aier and Ship and Shore Environmental team (hereinafter referred to as Aier & SSE) held a three-party talks with Jiangsu Environmental Protection Industry and Technology Research Institute (hereinafter referred to as Suhuanyuan). President Wu personally organized the Suhuan Academy. Experts participated in the meeting to jointly deploy a new strategy for the VOC market.During the meeting, the three parties elaborated on their advantages and experience in the VOC market and quickly found an opportunity for cooperation.As a environmental engineering company with many years of experience, Aier has rich application technology, strong production capacity and advanced design management system. SSE has more than 30 years of VOC governance experience and advanced intelligent control technology. The emergency device has a unique understanding and design, and has the advantage that the current peers can't match in terms of energy consumption. Suhuanyuan has a thorough understanding of the environmental protection regulations and related policies of Jiangsu Province and the market layout of the government's environmental protection governance. * A PhD team with a dynamic VOC governance study.The three parties have joined forces to provide practical solutions for VOC governance of enterprises, to implement the government's environmental protection policies, and to improve the quality of the living environment for the society.**, the three parties will conduct a detailed discussion on the VOC Technology Forum to be held next month, and improve related preparations. Looking forward to the spark of the tripartite cooperation in the magical bloom of the technical forum!
Aier Environmental and S&SE have joined forces to showcase the technologies, products and success stories of VOC governance and dust removal systems, attracting many visitors and the attention of exhibitors. Many customers came to inquire about the RTO/RCO system in detail, and many of them came to discuss the prospects of the VOC governance industry with us. The exhibition was very fruitful. Aier Environmental has the design capabilities of a total solution, specializing in pipeline layout, air volume balancing and system coordination; Aier Environmental and S & SE's technical advantages are high capture efficiency and high processing efficiency with small air volume. The domestic gap is more in line with the needs of the domestic market, and it stands out in the field of VOC governance.During the exhibition, the product of youthful vitality:Professional and unique case explanation:Enthusiastic professional answers:Handsome, confident and professional exhibitors:
At the signing ceremony, Ms. Liu Liyan, General Manager of Aier Environmental Protection, said that the company is actively focusing on VOC processing technology and related application industries, and is committed to making the company a leading domestic industry company with technical characteristics. In this regard, the Dean of the Institute expressed his firm confidence in the school-enterprise cooperation and hoped to promote more far-reaching development and achieve a win-win situation.
Calcium carbonate, starch can be used in the paper industry, can effectively improve the whiteness of the paper, improve the smoothness and softness of the paper, and improve the adsorption performance of the ink, so as to improve the retention rate. With the development of the paper industry, people's demand for paper is growing. In order to make calcium carbonate in the paper industry effectively reduce the pollution of the feeding operators and the on-site environment, our company has designed a pleated type for this kind of working condition research. Bag filter to improve the working environment.The case design is selected as follows:According to the on-site investigation, the inlet concentration of this working condition is relatively large (about 30g/m3), the dust is dust with humidity, and there are 2 dust removal points (the removal of dust from the calcium carbonate feed port, the starch dust removal port, plus 6 captures). The mouth is mainly used for indoor ventilation. When feeding, calcium carbonate and starch are separately fed. According to our design philosophy, the model of the pleated dust collector selected by the company is AR-XBH60 (for starch), the filtration area is 60 square meters, and the air volume is treated. 2500m3/h, filtration wind speed 1.4m/min; the other is AR-XBH80 (for calcium carbonate), the filtration area is 80 square meters, the treatment air volume is 5000m3/h, and the filtration wind speed is 1.45m/min. The working principle of the dust collector is that after the dust-containing gas generated during the feeding enters the dust collector under the guidance of the fan, a part of the coarse particles in the air flow settles to the ash bucket under the action of gravity and inertia force, and the granularity is fine. The small volume of dust enters the filter chamber, and the dust is retained on the surface of the filter bag. The purified gas enters the clean room and is discharged by the fan through the air outlet.
According to the different structural forms of the dust collector, Aier Environmental Design Pulse Spray Bag Dust Collector has two kinds of cleaning methods: online cleaning and offline cleaning.Online cleaningThe high-pressure pulsed air is ejected from the electromagnetic pulse valve through the gas pipe from the blowing hole above the center of the filter bag, passes through the neck of the venturi above the dust bag, including the induced secondary air, and rushes toward the inside of the filter bag. A short pulse pressure wave is generated in the longitudinal direction of the filter bag, and the dust deposited on the surface of the filter bag is peeled off, the dust falls into the ash hopper, and the clean gas is discharged outside the machine through the clean air chamber. When the solenoid valve is de-energized, the pulse valve diaphragm closes and stops the high-pressure pulse airflow, and the cleaning is completed once.The problem of on-line cleaning is that high-pressure pulsed air generates a high-pressure airflow reversed from the main airflow to filter the filter bag to shake the filter bag, remove the dust collected on the surface of the filter bag, and the dust falls into the ash hopper located in the lower part of the dust collector, and then The discharge device is discharged outside the machine. During this process, the high-pressure pulsed air has to overcome the resistance of the main airflow, and its strength is bound to be weakened. The effective filtration area of the precipitator is also reduced instantaneously (in milliseconds). From an industrial perspective, the impact of this area reduction on the process system is negligible. In recent years, bag cleaners for online cleaning methods have been widely used.
In the process of powder preparation and processing (such as pulverization, transportation, classification, mixing, roasting and drying), a large number of heterogeneous systems such as soot are produced, and the solid particles or liquid beads in the heterogeneous system are separated. The process that comes out is called separation. The two-phase separation of the gas-solid heterogeneous system is also referred to as dust removal/filtration.As a discharge separation equipment, Aier Environmental Dust Collector is the main equipment for intercepting materials in the transportation industry, because it is suitable only for high concentration inlet concentration and high filtration efficiency. The AR-RD series dust collectors developed by our company select the corresponding filter materials according to different materials and working conditions, and are equipped with fluidized devices such as rotary valves, gravity sensors, level gauges, vibrators and explosion-proof components and facilities. Automated control under different conditions.For example, our company designed an AR-RD30 dust collector for a German company (see Figure 1-1). The filter area is 30 square meters, all stainless steel material, it is suitable for separating NMC powder (NMC chemical name: lithium cobalt manganese manganate, is a raw material for battery, general flow, high temperature resistance, can not be mixed with any metal or other impurities) .
