Dongshi PSC series special injector for desulfurization regeneration tank of Changchun desulfurizati

  Since the early 1970s, Professor Gao Hua, the late desulfurization expert, has popularized and applied the desulfurization ejector regeneration technology researched and developed in most of his life in nitrogen fertilizer plants all over the country
By the beginning of the 21st century, this technology has been introduced into coking industry and other industries, and its application range is becoming wider and wider
In recent years, through long-term exploration and experiment, our company has deeply discussed the structure and working principle of the ejector, and finally developed PSC special jet oxidation regeneration ejector for desulfurization liquid
The ejector makes full use of the advantages of the parallel flow principle, and the desulfurization liquid forms a jet through the nozzle of the ejector at high speed
This jet generates local negative pressure to attract air
At this time, because the two-phase fluid is immediately dispersed at a high speed and in a high-speed turbulent state, the gas-liquid contact surface is greatly increased and constantly updated, so the mass transfer process progresses very rapidly Product structure The ejector is composed of a liquid inlet, a suction inlet, a liquid inlet pipe, a nozzle, an air chamber, a throat pipe, a diffusion pipe, a tail pipe, etc
Generally, when the inlet pressure is 0
4 ~ 0
5MPa, the flow rate at the nozzle is 18 ~ 25m / s, and the liquid injection volume of the ejector is determined by the size of the nozzle

The type selection of injectors shall be determined according to the production conditions of each factory
Our company can also manufacture special specifications and models of injectors according to the needs of users to meet the production needs of users
the transportation, installation and use of injectors require the matching of the main body of injectors The lower part of the throat shall be disassembled during placement and transportation, and the ejector itself shall be prevented from collision to avoid equipment deformation and concentricity
◆ the injector shall be installed vertically and concentrically
The tail pipe can be fixed on the channel steel support with clips
The orientation of the suction port can be determined according to the actual situation, but it shall ensure sufficient intake of fresh air
The main body of the ejector can be installed according to the scheme provided by the engineers and technicians of our company
◆ the working interface of each injector in the slot is about 2M2
The area of cross mixing area is generally not more than 0
5m2, and the number of injectors is determined in combination with the circulation amount of regeneration solution, desulfurization load, gas purification degree, types of removed gas and working conditions
The ejector shall be reasonably arranged in the groove
The size of the mixing pipe, diffuser and tail pipe of the ejector should be determined according to the height of the foam overflow weir, the height of the effective liquid surface and the height of the perforated plate, and the working conditions of each plant, so as to better meet the production needs
nbsp; Precautions ◆ when the ejector is working, the liquid inlet valve shall be fully opened, not half opened, otherwise it will affect the regeneration efficiency of rich liquid
◆ when the air suction volume decreases or a small amount of liquid splashes from the suction port, the ejector shall stop working and clean the sulfur scale and sundries in the nozzle, mixing pipe and cone bottom of negative pressure chamber
◆ our factory has the ability of precision casting and processing of ejector
All specifications of products have passed the inspection under simulated production conditions before leaving the factory
It is required to prevent damage or deformation during installation, maintenance and cleaning, so as not to affect the use effect Application performance after the product is put into the market, the effect is very remarkable and has been highly praised by the majority of customers
