T-shaped steam-water separator

Abstract

The invention relates to a T-shaped steam-water separator which is characterized by comprising a flow direction elbow, an output pipe, a shell, an upper seal head, a water accumulation tank and a bottom seal head, wherein the flow direction elbow passes through the side wall of the shell; the output pipe communicated with the shell is fixedly connected with the side wall of the shell opposite to the flow direction elbow; the upper part of the shell is fixedly connected with the upper seal head, and the lower part of the shell is fixedly connected with the water accumulation tank; the lower part of the water accumulation tank is fixedly connected with the bottom seal head; the center of the bottom of the bottom seal head is connected with a drain pipe connecting head communicated with the bottom seal head; the upper part of the output pipe of the shell is provided with a guide plate; a water retaining board is arranged at the part at which the upper part of the water accumulation tank is combined with the flow direction elbow. The T-shaped steam-water separator has the beneficial effects that the problem that water exits in the steam at the tail end of a steam supply pipe network can be solved, and the steam supply quality is improved. An atmospheric emission device system unit is assembled at a drain end, so that the problems of high sensible heat waste in water and system pressure relieve caused by installment of a steam trap valve for discharging high-temperature condensed water can be solved.

Description

technical field [0001] The invention belongs to a steam-water separator, in particular to a T-shaped steam-water separator used at the end of a steam branch pipeline. Background technique [0002] At present, there are three kinds of steam-water separators used at the end of steam branch pipelines: baffle type, cyclone type and adsorption type. The structures are different, and the purpose is to separate the condensed water produced in the process of steam transportation and the water molecules in the steam to improve the quality of steam supply. According to relevant information, the separation efficiency of the baffle type separator can be close to 100% when the flow rate is between 10m / s and 30m / s. The separation efficiency of cyclone and adsorption separators can only reach 98% when the steam velocity is below 13m / s, otherwise the efficiency will be very low. When the steam velocity is 25m / s, the separation efficiency is about 50%. Due to the structure of the above thr...

AI Technical Summary

Problems solved by technology

Due to the structure of the above three separators, there is a certain amount of heat energy internal consumption during the steam separation process.

Different types of water delivery valves are installed at the outlets, which not only cause waste of high sensible heat in condensed water, but also cause pressure relief in the system when the water delivery valve is discharged.
