Abstract
Description
Technical Field
[0001] The utility model relates to a sewage discharge device, in particular to a sewage discharge device for a high-pressure heater liquid level measuring pipe row, and the utility model is applied to the field of heat exchangers. Background Art
[0002] A horizontal heat exchanger refers to a heat exchanger installed horizontally rather than vertically. The cold and hot fluids inside it mainly flow horizontally as a whole rather than vertically. Since the equipment shell side will experience steam flushing during the initial startup of the heat exchanger, the initially entering steam scours the outer surface of the tubes and the inner surface of the shell, and dirt, rust, etc. are all discharged out of the shell together with the condensate water and dirt as the steam condenses. Since the shell is filled with heat exchange tubes and support plates, some slightly larger impurities will sink to the bottom of the equipment after being blocked and discharged. The liquid level measuring device of the high-pressure heater generally adopts an independent setting or a connecting pipe form, and a sewage discharge hole is opened on the lower connecting pipe for sewage discharge. However, the original structure is limited to discharging sewage on the lower connecting pipe, and impurities accumulate at the connection between the liquid level measuring connecting pipe and the connecting pipe, flowing into the liquid level measuring connecting pipe or the connecting pipe at the bottom and causing blockage, resulting in problems such as inaccurate liquid level measurement of false water levels, affecting the equipment performance indicators and even threatening the safe operation of the equipment. Content of the Utility Model
[0003] The purpose of the utility model is to solve the problem that the lower connecting pipe of the horizontal heat exchanger is limited to discharging sewage, and impurities accumulate at the connection between the liquid level measuring connecting pipe and the connecting pipe, flowing into the liquid level measuring connecting pipe or the connecting pipe at the bottom and causing blockage.
[0004] The technical solution adopted by the utility model to solve the above problems is as follows:
[0005] A sewage discharge device for a high-pressure heater liquid level measuring pipe row, which comprises a heater sewage discharge pipe, a heater shunt connection fitting, a measuring instrument connecting pipe, a dredging pipe and a dredging pipe sealing cover;
[0006] The top end of the heater sewage discharge pipe is hermetically connected to the liquid level measuring connecting pipe at the bottom of the heater, the bottom end of the heater sewage discharge pipe is hermetically communicated with the inlet end of the heater shunt connection fitting, the heater shunt connection fitting is provided with two shunt nozzles, one end of the measuring instrument connecting pipe is hermetically arranged with one shunt nozzle, the measuring instrument is installed at the other end of the measuring instrument connecting pipe, and one end of the other shunt nozzle is hermetically communicated with one end of the dredging pipe, and the dredging pipe sealing cover is hermetically and fixedly installed at the other end of the dredging pipe.
[0007] Further, the heater shunt connection fitting is a three-way pipe joint.
[0008] Further, the inlet of the heater shunt connection fitting is vertically arranged in the same plane as the two shunt nozzles.
[0009] Furthermore, the length of the measuring instrument connecting pipe is greater than the length of the dredging pipe.
[0010] Furthermore, the length of the dredging pipe is 150 mm, and the sealing pipe cover of the dredging pipe is seal-welded at the end of the dredging pipe.
[0011] Beneficial effects of the utility model:
[0012] The purpose of this utility model is to provide a boiler combustion system with an ammonia burner. The effects of this utility model are as follows:

It can reduce the on-site maintenance cost, improve the quality of the product, and greatly enhance the market competitiveness of the product in the same industry and improve the brand image.
[0014] 2. One of the shunt pipe openings of the heater shunt connection pipe fitting 2 of the present application is connected to the measuring instrument connection pipe 3, and the other shunt pipe opening of the heater shunt connection pipe fitting 2 is connected to the dredging pipe 4. The dredging pipe sealing pipe cover 5 is welded to the end of the dredging pipe 4. When it is necessary to dredge impurities, the dredging pipe sealing pipe cover 5 is cut off. Since only 150mm is dredged, the pipe cover is welded. The dredging pipe 4 here can be cut repeatedly. This device can provide a feasible sewage discharge structure for the heat exchanger, solve the sewage discharge problem at the bottom of the heat exchanger, and is easy to install.
