Description

Technical Field

[0001] The utility model belongs to the technical field of ship boiler water supply, in particular to a ship boiler water supply device. Background Art

[0002] Solid particles are often inevitably generated during the actual construction, operation and maintenance of boiler water supply systems. Over time, they begin to accumulate at sharp bends, valves and other nodes in the system, causing system blockage. Once a key node is blocked and the system stops, not only is it very tedious to find the blockage point, it is also a serious threat to the operational safety of the ship in extreme sea conditions. If it cannot be repaired in time, there may even be a risk of capsizing.

[0003] Ordinary hot well arrangements mainly rely on oil detectors and observation mirrors in condensate observation cabinets to detect dirty oil. However, in actual operation, due to system pressure fluctuations, the oil-water separation layer is extremely unstable, resulting in a large number of small oil droplets that cannot float to the water surface smoothly due to fluid disturbances. When the pressure continues to increase, the liquid level can even be pressed down to below the designed liquid level, resulting in abnormal system alarms and inability to remove dirty oil, affecting boiler water quality.

[0004] Previous designs could not solve these problems, so new devices were needed to address them. Utility Model Content

[0005] In view of the above problems, the utility model provides a marine boiler water supply device, which can quickly and effectively remove solid particles in the boiler water supply system and improve the hot well degreasing efficiency.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A marine boiler water supply device comprises a cabinet body, wherein the interior of the cabinet body is divided into a hot well and a condensate observation cabinet by a partition, the condensate observation cabinet is located in the middle and upper part of one side of the cabinet body, a buffer cabinet is arranged by a partition in the middle and upper part of the hot well close to the condensate observation cabinet, the width of the buffer cabinet is smaller than the width of the hot well, the condensate observation cabinet and the buffer cabinet are connected by an internal connecting pipe located inside the condensate observation cabinet, the inlet of the internal connecting pipe is located at the bottom of the condensate observation cabinet, and the outlet of the internal connecting pipe is fixed to the partition between the condensate observation cabinet and the buffer cabinet; a through hole is opened on the lower end surface of the buffer cabinet, a partition bulkhead is vertically arranged on the lower end surface of the hot well, the partition bulkhead is located directly below the side wall of the buffer cabinet away from the condensate observation cabinet, the top of the partition bulkhead is spaced apart from the lower end surface of the condensate observation cabinet, and the hot well is connected to the boiler through a pipeline.

[0008] Furthermore, the top of the hot well and the top of the condensate observation cabinet are connected through a ventilation pipe, the ventilation pipe is located outside the hot well and the condensate observation cabinet, and the ventilation pipe is connected to the oil mist box through a ventilation branch pipe.

[0009] Furthermore, an oil drain funnel is provided inside the condensate observation cabinet, the oil drain funnel is connected to an oil drain pipe, the inlet of the oil drain pipe is located inside the condensate observation cabinet, and the outlet of the oil drain pipe passes through the bottom wall of the cabinet and is connected to the bilge water tank.

[0010] Furthermore, a bottom drain valve connected to the hot well is provided directly below the condensate observation cabinet, and the bottom drain valve is connected to the oil drain pipeline.

[0011] Furthermore, a manhole is opened on the side wall of the hot well, and a manhole cover is provided at the manhole.

[0012] Furthermore, inspection holes and inspection hole covers are provided on the cabinet top covers located directly above the buffer cabinet and the condensate observation cabinet.

[0013] Furthermore, an oil detector is provided on the side wall of the condensate observation cabinet opposite to the oil drain funnel.

[0014] In the marine boiler water supply device of the utility model, the partition wall added in the hot well can prevent solid particles from moving to the boiler water supply side. The solid particles sink to the bottom of the hot well under the action of gravity and are discharged to the bilge water tank through the sewage valve at the bottom; the clean water at the upper part passes over the partition wall and enters the boiler water supply side, and enters the system circulation through the boiler feed water pump, so as to achieve the purpose of purifying the water quality of the water supply.

[0015] The condensate observation cabinet and the hot well are interconnected through a breathable pipe. Through the isobaric principle, the condensate observation cabinet and the internal pressure of the hot well can always be kept equal to the atmospheric pressure. First, the pressure disturbance of the system on the condensate observation cabinet will be reduced, and the stability of the oil-water separation membrane will be improved, which can promote the efficiency of oil-water separation and enhance the oil removal efficiency of the hot well; secondly, it can completely eliminate the system false alarm caused by the drop in the liquid level of the condensate cabinet due to the sudden change of pressure, and the problem that the oil removal funnel cannot remove oil.

DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] like Figure 1 As shown, a marine boiler water supply device comprises a cabinet body, wherein the cabinet body is divided into a hot well 1 and a condensate observation cabinet 2 by a partition inside the cabinet body, the condensate observation cabinet 2 is located in the middle and upper part of one side of the cabinet body, and a buffer cabinet 11 is separated by a partition in the middle and upper part of the hot well 1 near the condensate observation cabinet 2, the width of the buffer cabinet 11 is smaller than the width of the hot well 1, the condensate observation cabinet 2 and the buffer cabinet 11 are connected through an internal connecting pipe 13 located inside the condensate observation cabinet 2, the inlet of the internal connecting pipe 13 is located at the bottom of the condensate observation cabinet 2, and the outlet of the internal connecting pipe 13 is fixed to the partition between the condensate observation cabinet 2 and the buffer cabinet 11; a through hole 111 is opened on the lower end surface of the buffer cabinet 11, and a partition wall 3 is vertically provided on the lower end surface inside the hot well 1, the partition wall 3 is located directly below the side wall of the buffer cabinet 11 away from the condensate observation cabinet 2, the top of the partition wall 3 is spaced from the lower end surface of the condensate observation cabinet 2, and the hot well 1 is connected to the boiler through a pipeline.

[0020] The top of the hot well 1 and the top of the condensate observation cabinet 2 are connected through an air vent 6, and the air vent 6 is located outside the hot well 1 and the condensate observation cabinet 2, and the air vent 6 is connected to the oil mist box through a air branch pipe 12; an oil drain funnel 7 is provided inside the condensate observation cabinet 2, and the oil drain funnel 7 is connected to the oil drain pipe 5, the inlet of the oil drain pipe 5 is located inside the condensate observation cabinet 2, and the outlet of the oil drain pipe 5 passes through the bottom wall of the cabinet and is connected to the bilge water tank; a bottom drain valve 4 connected to the hot well 1 is provided directly below the condensate observation cabinet 2, and the bottom drain valve 4 is connected to the oil drain pipe 5; an oil detector 8 is provided on the side wall of the condensate observation cabinet 2 opposite to the oil drain funnel 7.

[0022] By adopting the marine boiler water supply device of this embodiment, firstly, the solid particles brought by the condensate backflow will stop moving under the action of the partition wall 3. Due to the blocking effect of the partition wall 3, the liquid speed decreases and moves upward along the bulkhead. At this time, the solid particles will settle under the action of gravity, and the condensate that has completed the sedimentation at the top will pass over the partition wall 3 and enter another cavity, and enter the boiler water supply system circulation again; secondly, when the internal pressure of the system is abnormal, the condensate observation cabinet 2 can be connected to the hot well 1 body and the atmosphere through the air permeable pipe 6 to quickly absorb the abnormal pressure, so that the stability of the oil-water separation layer will not be destroyed, and the system false alarm and oil removal failure caused by the drop in liquid level due to sudden pressure change can be avoided.
