Integrated large PP reactor

Dongying PP Reactor*

The Standard specifies the start and end dates for calculating heating and cooling demand in major cities in Hebei Province, and provides detailed calculation methods for building energy consumption, air conditioning load, and primary energy demand in the calculation of heating, cooling, and total primary energy demand for buildings. This also provides technical support for the "Standard" to limit the building energy consumption, air conditioning load, and primary energy demand of passive houses. The insulation and excellent airtightness of passive rooms determine that fresh air must be supplied to ensure an excellent indoor environment. To minimize the energy consumption of fresh air, passive rooms require that the fresh air system must have a heat recovery function with a heat recovery efficiency of 75%.

Relying solely on a single method for remediation of POPs pollution has many problems, such as failure to meet remediation requirements, high costs, reduced or lost soil use value after remediation, etc. Therefore, it is necessary to integrate multiple methods to achieve effective, low consumption, and safe remediation. Under this requirement, the connotations of bioremediation and joint restoration appear too simplistic, thus raising the issue of ecological restoration. The concept of ecological restoration mainly focuses on two areas: environmental protection and nature conservation. The concept of ecological restoration proposed in the field of nature conservation mainly focuses on the restoration of disturbed or damaged ecosystems, such as soil and water conservation and ecological restoration of mines. The concept of ecological restoration proposed in the field of environmental protection is represented by Sun Tieheng's viewpoint: pollution ecological restoration is different from biological restoration. Biological restoration uses organisms and microorganisms with purification functions to reduce and purify pollutants, which is a simple biological restoration. Ecological restoration emphasizes the regulation of environmental factors such as soil moisture, soil nutrients, soil pH value, soil redox status, temperature, humidity, etc. to achieve the biological purification function of pollutants in the environment medium water, gas, soil, life, etc.

The polypropylene (PP) (vacuum) measuring tank produced by our company is a tasteless high crystalline polymer plastic material that can store various acids and alkalis. It has anti-corrosion properties and can store the vast majority of organic and inorganic acids, alkali salts, and some organic solvents. It is a commonly used material in the field of anti-corrosion. Mainly suitable for industries such as chemical, pharmaceutical, and petroleum, it has the advantages of light weight, easy installation and maintenance, and simple operation.

The body of Summa tank mainly has two types: polishing treatment and silanization. The Summa stainless steel tank sampling technique, which is a classic polishing treatment, is the standard method adopted by EP in the United States (TO-1TO-15). During sampling, a pump is used to collect positive pressure from the air in the tank, which is often used for the analysis of non-polar substances. Its advantage is that it can avoid penetration decomposition and analysis during adsorbent sampling, but the sampling equipment is expensive, the preparation of standard samples and the cleaning of tanks are time-consuming and laborious, and it cannot pre concentrate the samples. Stainless steel sampling tank technology is widely used in the determination of volatile organic compounds. Batterman et al. found that the half-life of aldehydes and terpenes in humid air filled tanks was 18 days, 24 days in humid nitrogen gas, and as short as 6 days in dry air when analyzing and storing volatile organic compounds using polished Summa tanks. Research has shown that Summa tanks require a certain level of humidity when storing organic compounds.

Application areas: Vacuum measuring tank, high-level tank, mainly suitable for industries such as chemical and petroleum, and boring vacuum machine quantities in production processes. It has the advantages of light weight, easy installation and maintenance, and simple operation. Its operating pressure: ≤ -0.1MPa, stable operation -10 ° C~120 ° C
Installation guide: The diameter of simplified Chinese characters, flange size, and the use of hanging or supporting feet for equipment are determined by the customer. The hanging foot position is generally welded at the upper third of the cylinder. There are two forms of liquid level gauges: (1) PTFE tube (2) glass level gauge

Some regions have recognized the seriousness of the sludge problem and there are no difficulties in construction investment, but they cannot determine the treatment and disposal technology solutions, and each solution is opposed by some people. Some regions blindly determine treatment and disposal plans without conducting systematic investigations and research on local sludge quality, soil conditions, etc. Some regions tend to adopt seemingly simple and quick treatment and disposal methods such as landfill or incineration, without studying treatment and disposal technology routes from the perspective of ecological circulation and sustainable development. Some people believe that the technical route for sludge treatment and disposal should be selected according to local characteristics and should not be a one size fits all approach. This viewpoint is certainly correct. The question is what principles should be followed to adapt to local conditions, and which local characteristics should be the main consideration factors. There is no unified understanding in these aspects, and technical solutions still cannot be chosen.

Product features: PP vacuum tank, consisting of one tank body and one tank cover, with a suction device and an air chamber inside the tank cover. The suction device contains a plunger, and the air chamber is equipped with several check valves; The air chamber is located inside the tank cover, with a recessed space above the tank cover for accommodating a rod body. The end of the rod body is pivot connected to the end of the plunger, and the predetermined position of the rod body is pivot connected to the accommodating space of the tank cover. The air chamber has several inlet holes and valve holes, each of which is equipped with a check valve. An elastic element is placed inside the air chamber, and the elastic element is used to push the plunger; Based on this, by rotating the rod body, the plunger is driven to move back and forth in the chamber, allowing the gas in the tank to enter the chamber through the inlet hole and be discharged through the valve hole. The plunger is then restored to its original state through an elastic element, achieving effortless operation with a lever and efficient extraction of air.

The inner and middle tubes of the MPT torch tube are connected by a terminal short-circuit piston, making it a coaxial microwave resonant cavity. There are three coupling methods for coaxial resonant cavities: direct coupling, capacitive coupling, and inductive coupling. Direct coupling, also known as conductive coupling, involves opening holes in the outer conductor of the coaxial cavity and directly connecting the inner conductor of the coaxial transmission line (antenna) to the inner conductor of the coaxial cavity. MPT torch tubes use this method. When the distance from the top of the torch tube to the end face of the tuning piston is an odd multiple of 4 (usually 3/4), the electric field at the top is strong, and plasma can be formed and maintained at the top. It is a microwave plasma torch system from the High Energy Institute of the University of Electronic Science and Technology of China. The working frequency of the microwave is 2.45 GHz. The microwave generated by the magnetron is coupled to the coaxial transmission line (antenna) through a waveguide system, three terminal matching, and short-circuit piston, and forms a specific electromagnetic field distribution a few centimeters away from the inner tube port, thereby ionizing working gases such as air to form a plasma torch. The flame length of the plasma torch in the figure is only a few centimeters, and its main applications are diamond films, surface modification of materials, chemical analysis, preparation of nanomaterials, waste treatment, etc.
