Draining and moisture exhaust device for direct-buried steam pipe

Abstract

The invention discloses a draining and moisture exhaust device for a direct-buried steam pipe. The draining and moisture exhaust device comprises a water collector connected with a working pipe. The draining and moisture exhaust device is characterized by further comprising a cooling water tank, a division plate is arranged in the middle of the cooling water tank, and the cooling water tank is divided into an upper water tank and a lower water tank by the division plate; a baffle plate is arranged under the middle of the division plate, and the lower end of the baffle plate is not connected with the bottom of the cooling water tank; a water drain pipe is arranged on the side face of the cooling water tank; the water collector is communicated with a drain pipe, the drain pipe is provided with a casing pipe, and a gap exists between the drain pipe and the casing pipe; the drain pipe is provided with a drain valve group, and the outlet of the drain pipe is communicated with the lower part of the cooling water tank; the casing pipe is communicated with a moisture exhaust pipe, and the outlet of the moisture exhaust pipe is arranged on the outer surface of the upper part of the cooling water tank; the moisture exhaust pipe is provided with a gate valve and a float ball valve, the float ball valve is connected with a float ball device, and the float ball of the float ball device is positioned under the division plate. The draining and moisture exhaust device solves the problems that the condensate water of the direct-buried pipe is drained and steamed, moisture cannot be exhausted and accumulated water flows backward.

Description

technical field [0001] The field of the invention belongs to the field of directly buried steam pipes, specifically the field of water drainage and moisture drainage of directly buried steam pipes. Background technique [0002] At present, during the operation of the directly buried steam pipe, the working pipe will produce condensed water. For the drainage and drainage of directly buried prefabricated thermal insulation steam pipelines in engineering, the general practice is to install drainage pipe fittings at the drainage points, connect the condensate outlet pipe of the drainage pipe fittings to the steam trap group, and the condensate discharge pipe of the steam trap group into the drainage well chamber sump unit. Because the water temperature of the steam pipe is very high, the temperature of the condensed water flowing out is also high, and hot gas will emerge from the water collecting well. With the gradual improvement of municipal engineering requirements, hot air...

AI Technical Summary

Problems solved by technology

If the moisture is not removed in time, the material life of the insulation layer will be greatly reduced, and the heat loss of the entire pipeline will gradually increase, affecting the thermal efficiency and service life of the pipeline
