Description

Technical Field

[0001] The utility model relates to a drainage device for a flue gas reheater, and more specifically to a condensate collecting tank for a flue gas reheater of an incinerator. Background Art

[0002] The existing incinerator flue gas reheater drainage device consists of a drainage pipe and a drainage manual valve. If the drainage is not timely, it is easy to cause internal corrosion and blockage of the equipment. Negative pressure drainage will cause the atmosphere to be sucked back into the system, affecting the flue gas environmental protection indicators. At present, drainage operations are carried out by manually timing the opening and closing of valves. If personnel are negligent and fail to drain the water inside the reheater in time, it is easy to cause blockage and corrosion of the equipment. In addition, the pipe is directly connected to the valve. When the reheater is drained under negative pressure, some atmosphere will be sucked back into the system, affecting the exhaust gas environmental protection indicators.

[0003] In summary, the existing manual drainage will lead to an increase in labor costs, and there are problems such as untimely drainage, easy corrosion, equipment clogging, and negative pressure drainage causing atmospheric backdraft into the system, affecting the environmental protection indicators of flue gas. Utility Model Content

[0004] In view of the defects existing in the prior art, the purpose of the utility model is to provide a condensate collection tank for the flue gas reheater of the incinerator, which realizes automatic drainage and solves the problems of cumbersome manual drainage and untimely drainage, atmospheric back suction during negative pressure drainage of the reheater affecting the environmental protection indicators of the exhaust gas, and the problem of easy corrosion and blockage inside the equipment.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A condensate collecting tank for an incinerator flue gas reheater, comprising a condensate collecting tank body;

[0007] A high liquid level gauge and a water inlet pipe are provided on the upper part of the condensate collection tank body;

[0008] A low liquid level gauge and a drain pipe are provided at the lower part of the condensate collection tank body;

[0009] The water inlet pipe is provided with a water inlet valve, and the drain pipe is provided with a drain valve;

[0010] The high liquid level meter is connected to the drain valve by signal;

[0011] The low liquid level meter is signal-connected to the water inlet valve.

[0012] Preferably, the high liquid level gauge and the low liquid level gauge are both float type liquid level gauges.

[0013] Preferably, a liquid level observation port is provided on the condensate collection tank body.

[0014] The utility model provides a condensate collection tank for an incinerator flue gas reheater, specifically the following points

[0015] Beneficial effects:

[0016] 1. The condensate tank can collect the condensate inside the equipment in real time to form a water seal, avoiding problems such as equipment corrosion and pipeline blockage caused by the condensate remaining inside the equipment;

[0017] 2. Since the reheater is drained under negative pressure, this product prevents atmospheric back-inhalation through the water seal principle, thus preventing the atmosphere from entering the system and affecting the flue gas index, thus ensuring operational stability;

[0018] 3. It can simplify the drainage process, eliminating the need for frequent manual valve opening and closing, thus freeing up labor;

[0019] 4. The condensate tank is equipped with a liquid level observation port, which can monitor the liquid level of the condensate tank in real time. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 1 It is a structural schematic diagram of the condensate collecting tank of the utility model. DETAILED DESCRIPTION

[0021] In order to better understand the above technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0022] Combination Figure 1 As shown, the utility model provides a condensate collecting tank for an incinerator flue gas reheater, comprising a condensate collecting tank body 100 .

[0023] A high liquid level gauge 1 and a water inlet pipe 2 are installed on the upper part of the condensate collecting tank body 100 .

[0024] A low liquid level gauge 3 and a drain pipe 4 are installed at the lower part of the condensate collecting tank body 100 .

[0025] The water inlet pipe 2 is provided with a water inlet valve 5 , and the water discharge pipe 4 is provided with a water discharge valve 6 .

[0026] The high liquid level meter 1 is signal connected to the drain valve 6 .

[0027] The low liquid level meter 3 is signal-connected to the water inlet valve 5 .

[0028] The high liquid level gauge 1 and the low liquid level gauge 3 are both float type liquid level gauges.

[0029] The condensate collecting tank body 100 is also provided with a liquid level observation port 7 .

[0030] When the condensate collecting tank of the utility model is working, when the condensate has not reached the high liquid level, the low liquid level gauge 3 detects and triggers the water inlet valve 5 to open, and the condensate inside the reheater will be discharged into the condensate collecting tank in real time to form a water seal to prevent atmospheric back suction. When the liquid level reaches the high liquid level of the condensate tank, the high liquid level gauge 1 detects and triggers the drain valve 6 to open, and the automatic drainage operation begins. At this time, the top water inlet valve 5 is automatically closed and the bottom drain valve 6 is automatically opened. When the liquid level drops to the low liquid level, the drainage operation automatically stops, and the bottom drain valve 6 is automatically closed and the top water inlet valve 5 is automatically opened, and so on.

[0031] The utility model condensate collecting tank realizes automatic operation of reheater drainage through combined control of water inlet valve 5 and drainage valve 6, reduces manual labor, collects condensate in the reheater in real time through the condensate collecting tank with float level gauge (high level gauge 1 and low level gauge 3), and can form a water seal while effectively preventing the condensate from corroding and clogging the inside of the equipment. The water seal generated by the condensate successfully solves the difficulty that the atmosphere will be sucked back into the system during negative pressure drainage of the reheater to affect the environmental protection indicators of the exhaust gas.

[0032] The condensate collection tank of the utility model can collect the condensate in the flue gas reheater in real time to form a water seal, prevent corrosion, prevent clogging, and prevent atmospheric backflow during negative pressure drainage. It can be used for drainage of negative pressure equipment such as flue gas reheaters. This drainage device can automatically drain water, reduce manual labor, and effectively prevent atmospheric backflow from affecting the environmental protection indicators of flue gas.

[0033] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present invention, and are not intended to limit the present invention. As long as they are within the spirit of the present invention, any changes or modifications to the above embodiments will fall within the scope of the claims of the present invention.
