​Recently, some customers have inquired about the centralized oil mist treatment plan of CNC workshop. In this article, we will briefly introduce it.

Yesterday, a knowledgeable middleman (a person in the industry) called for consultation. He asked a question: Is it possible for a meltblown cloth manufacturer to use a pure high-voltage electrostatic fume purifier to deal with the oily waste gas of more than 200 degrees produced by the setting machine? I thought this question was very strange, so I asked him if he had taken our goods, but now there is a problem. He said no. After careful inquiries, it turns out that he learned our solution from the information we published online the year before last, and then bought a few thousand yuan from somewhere in Shandong that looked similar to our home and installed it. It's been a little over a year since it burned down.

​In the field of lampblack treatment, pure high voltage electrostatic lampblack purifier and high and low voltage electrostatic lampblack purifier are the two most widely used products. In the current product line of our company, ESM and ESM-S are high and low voltage electrostatic type, while PSH and PSM-S are pure high voltage electrostatic type. The applicable objects of the two products overlap somewhat, but they do not seem to be exactly the same. Many people are confused. This article simply answers this question.

​According to the description in "Technical Requirements for Environmental Protection of Heat Treatment GB/T 30822-2014", the main exhaust gas pollutants produced in the quenching process are oil fume due to the use of quenching oil and tempering oil. According to the instructions in "Limits of Hazardous Substances in the Air of Workplaces in Heat Treatment GB/T 27946-2011", the waste gas pollutants generated in the process of low-temperature salt baths such as graded quenching and tempering, and aluminum alloy solid solution aging salt baths are carbon dioxide. , hydrogen chloride and hydrochloric acid, hydrogen, potassium hydroxide, sodium hydroxide, carbon dioxide, sulfur dioxide, hydrogen cyanide and cyanide. The atmosphere of carburizing and hydrocarburizing and tempering and quenching oil will produce oil mist, nitrogen dioxide, carbon monoxide, carbon dioxide, and carbon black dust.

​1. Basic information of the project
Pollution source: soot from 2 welding workshops;
Riveting workshop 1: length 120m, width 18m
Riveting workshop 2: length 80m, width 18m
Pollution source collection method: blowing suction type welding fume collection system
Dust purification equipment: our company's filter cartridge type smoke and dust purification integrated machine

​The temperature of forging is generally higher than 400 ℃. In order to prolong the life of the mold, a mold release agent must be used to protect the mold from corrosion. The hot forging release agent usually consists of 3 parts: the matrix that mainly plays a lubricating role, the carrier solvent and the additives that improve the comprehensive performance of the lubricant, such as extreme pressure agents, tackifiers and antioxidants. Graphite, molybdenum disulfide and compound stearate are typical solid lubricant bases. Because graphite emulsion has good lubricity, high temperature stability and adhesion characteristics at high temperature, it is widely used in the field of hot forming. Now hot die forging is released. The agent generally uses water-based graphite milk.

​There are many types of industrial processing fluids, and they are also commonly used in the production process. It is a matter of great significance to minimize the concentration of oil mist in the air, which is not only beneficial to the health of employees, but also to the long-term health of enterprises. development.

Industrial oil fume purifier and industrial oil mist purifier are two product terms that we commonly use. Many peers default that these two products are the same. Even some search engines and third-party platforms don't make a distinction, so that users often see both types of products mixed together when searching for these two terms. So, this article will briefly discuss this issue.

Due to the popularity of environmental protection inspections and environmental protection knowledge, many users have learned that the adsorption capacity of activated carbon reaches saturation after a certain period of use when purchasing activated carbon boxes. Risk of Departmental Penalties. Therefore, we are often asked by some rational users how do you calculate the replacement cycle of activated carbon? How often does our activated carbon need to be replaced?

Since I answered the consultation call as a customer service agent, I have encountered an unknown number of customers asking: How to deal with the oil fume produced by the heating and melting of polyethylene (or other thermoplastic resins)? At present, a two-stage activated carbon adsorption device is used, which cannot filter the oil in the exhaust gas, and the oil is sucked into the fan.
