Pipe water dividing/catching device for high temperature cooler

Abstract

The invention relates to the technical field of a cooler, in particular to a pipe water dividing / catching device pipe water dividing / catching device for a high temperature cooler. The a pipe water dividing / catching device comprises a rounded water cavity, a seat flange, a sealing flange and a connecting pipe, wherein the rounded water cavity is provided with a hollow cavity body, a water inlet hole is formed in the front end face of the rounded water cavity, a plurality of pipe connecting openings connected with a heat exchanging pipe are formed in both the circumference and the bottom end surface of the rounded water cavity, one end of the seat flange is inserted in the opening hole of the shell of the high temperature cooler, the sealing flange, the seat flange and the open hole are allarranged in a coaxial mode, one end of the connecting pipe, connected with the rounded water cavity, communicates with the hollow cavity body through the water inlet holes, and the other end of the connecting pipe penetrates through the inner holes of the seat flange and the sealing flange and extends out of the outer side of the shell of the high temperature cooler to be connected with the watersupply pipe outside the shell. According to the pipe water dividing / catching device, the convey of cooling water is achieved under the condition that the highly efficient heat exchange of the high temperature cooler is not influenced, the structure is further simple, the space occupied is small, and the structural design of the high temperature cooler is not influenced.

Description

technical field [0001] The invention relates to the technical field of coolers, in particular to a tube-side water diversion / collection device of a high-temperature cooler. Background technique [0002] The high temperature cooler is the most important heat exchange system in the arc wind tunnel. Conventional industry standard shell-and-tube heat exchangers usually adopt the method of adding heads and partitions at both ends of the cooler shell to design the inlet and outlet of cold fluid (such as water, etc.), and the cooling fluid and hot fluid are separated by tube sheets, but for For large-scale high-temperature gas coolers, this design type is not suitable. The main reasons are as follows: First, the inlet of the arc wind tunnel high-temperature cooler is connected to the outlet of the wind tunnel diffuser, and the outlet is connected to the vacuum system. In addition to the heat exchange function, it also has the function of a fluid channel. Therefore, both ends The ...

Conventional industry standard shell-and-tube heat exchangers usually adopt the method of adding heads and partitions at both ends of the cooler shell to design the inlet and outlet of cold fluid (such as water, etc.), and the cooling fluid and hot fluid are separated by tube sheets, but for For large-scale high-temperature gas coolers, this design type is not suitable

The main reasons are as follows: First, the inlet of the arc wind tunnel high-temperature cooler is connected to the outlet of the wind tunnel diffuser, and the outlet is connected to the vacuum system. In addition to the heat exchange function, it also has the function of a fluid channel. Therefore, both ends The design of the head and partition can not meet the actual needs

The second is that the gas-sweeping tube bundle is usually used, and the heat exchange tubes inside the shell are not of the same specification, so it is difficult to use the head and partition type to realize the transportation of cooling fluid; the third is that the maximum enthalpy of the high-temperature gas in the arc wind tunnel can reach 30MJ / kg (the temperature can exceed 6000K), when the tube bundles of different specifications at all levels are connected in U-shape, in order to prevent the overheating of the tube bundle caused by the excessive pressure drop of the cooling fluid, the cooling water flow required by the heat exchange tube is different; the fourth is the arc wind The operating conditions of the hole are changeable, and the sealing structure design of the cooling water flow in and out of the shell is unreasonable, which may easily cause cooling water leakage
