The branch cylinder is the main supporting equipment of the boiler, which is used to distribute the steam generated during the operation of the boiler to each pipeline. The branch cylinder is a pressure bearing equipment, which is a pressure vessel. Its pressure bearing capacity and capacity should correspond to the supporting boiler. The main pressure components of the branch cylinder are: head, shell materials, etc. The main pressure components of the branch cylinder equipment are: the head, shell and flange materials are Q

The heat transfer oil cooler is composed of shell, heat transfer tube bundle, tube plate, baffle plate (baffle), tube box and other components. The shell is mostly cylindrical, with tube bundles installed inside, and both ends of the tube bundle are fixed on the tube plate. There are two kinds of cold and hot fluids for heat exchange, one is flowing in the tube, which is called tube side fluid; The other flow outside the tube is called shell side fluid. In order to improve the heat transfer coefficient of the fluid outside the pipe

U-tube heat exchanger is a kind of shell and tube heat exchanger, which belongs to petrochemical equipment. It is composed of main parts such as tube box, shell and tube bundle. It is named because its heat exchange tube is U-shaped. The U-tube heat exchanger has only one tube sheet, and both ends of the tube are fixed on the same tube sheet. Structure performance: this type of heat exchanger is characterized by free expansion of the tube bundle, which will not generate heat due to the temperature difference between the tubes and shells

Pneumatic conveying device Pneumatic conveying refers to conveying granular materials by fluidizing the materials with the flowing air (or gas) in the pipeline. It is a common method for conveying dust in dust removal engineering. In the process of transportation, the pipeline presents a two-phase flow state of gas and solid. In the two streams, the ratio of the amount of material transported per unit time to the amount of air consumed is called the "material gas ratio", also known as the "solid gas ratio"

Bin pump There are two unloading methods for bin pump, of which the bottom discharge is a common method. The materials in the tank are fluidized through the conical inflatable trough, nozzle jet or other methods; Fluidized aeration plate (layer) is arranged at the bottom to discharge materials from the upper part of the tank. The distribution of transported gas on different input planes in the tank depends on the properties of transported materials. warehouse
