Description of the invention (丨) [Technical field of industrial utilization] The present invention relates to a dust removal device for a funnel for flushing water drainage of a rotary regenerative heat exchanger, especially A dust removing device for a funnel for flushing water drainage that removes dust and the like accumulated on the surface of the heat transfer element of a rotary regenerative heat exchanger used in power plants and the like without stopping the plant. [Conventional Technology] The heat transfer element of the rotary regenerative heat exchanger used in general power plants and the like can cause clogging of the fluid flow path due to the adhesion of dust and the like during operation, leading to an increase in pressure loss. In this case, in order to remove dust and the like attached to the surface of the heat transfer element, steam or air is sprayed from the soot blower. When soot blowers cannot be removed sufficiently, the factory must be stopped for washing. [Problems to be solved by the invention] However, in recent years, due to some circumstances, many cases cannot be stopped by the factory. It was later developed (Japanese Unexamined Patent Publication No. 6 1 2 8 9 2 9 6) and it was possible to flush the device even during the operation of the plant and put it into practical use. After being blocked, the drain fills the entire funnel and overflows from the funnel to the downstream of the heat exchanger, which has a bad influence on various machines on the downstream side, and if the mechanical strength of the funnel is exceeded Funnel duct or expansion failure. Therefore, it is true that there is no specific technique for countermeasures and it is necessary to give up the washing operation in operation. The present invention is to solve the above-mentioned problems, and its purpose is to: This paper scale is applicable to the Chinese National Standard (CNS) Λ4 specification (210X297 mm) I --------- {------- 1T- ----- ^ I (Please read the precautions on the back before filling in this page) -4-311983 A7 B7 V. Description of invention (2) Provided near the drain of the funnel for flushing water drainage to spray during backwashing, By removing the dust blocking the drain, etc., the flushing water in operation can be smoothly discharged. The dust removal device for the flushing water drain funnel of the rotary regenerative heat exchanger "[Means to solve the problem] 1 The present invention The dust removal device of the funnel for flushing water drainage of the rotary regenerative heat exchanger has the following characteristics: The tapered duct for the fluid inlet and outlet is connected to the upper and lower shells of the rotor containing the heat transfer element, on the high temperature fluid side A flushing device is arranged in the tapered duct, and a funnel for flushing water drainage is connected below the tapered duct at the bottom, and a rotary regenerative heat exchanger of the funnel drain port and the drain valve is arranged at the bottom of the funnel, and a pipe for backwash water is connected In the above Between the hopper drain and the drain valve, the overflow drain and the drain valve are arranged on the upper part of the funnel, and a pipe for backwash water is connected between the overflow drain and the drain valve, and at the same time, the backwash water is used The pipeline is equipped with a backwash valve. [Embodiment of the present invention] The following is a detailed description of one embodiment of the present invention with reference to the drawings. In FIG. 1, 1 is a casing of a rotary regenerative heat exchanger that houses a rotor 2. The rotor 2 is filled with a heat transfer element 3. A tapered conduit 4 for low-temperature fluid inlet, a tapered conduit 5 for low-temperature fluid outlet, a tapered conduit 6 (imaginary line) for high-temperature fluid inlet, and a tapered conduit 7 for high-temperature fluid outlet are connected to the housing. The above-mentioned low-temperature fluid, for example: If the standard of boiler paper is applicable to China National Standard (CNS) A4 specification (210X 297mm) I --------- ~ ------ 1T ----- -(Please read the precautions on the back before filling out this page) Printed by the Ministry of Economy Central Standards Bureau Employee Consumer Cooperatives Printed by the Ministry of Economic Affairs Central Standards Bureau Employee Consumer Cooperatives A7 ___B7 5. Description of the invention (3) The factory is outside air, if In the desulfurization plant, it is treated gas; the above-mentioned high-temperature fluid, for example: exhaust gas in the boiler plant, and untreated gas in the desulfurization plant. As shown in FIG. 2, the high-pressure fluid inlet tapered duct 6 is provided with a high-pressure washing device 8, a soot blower 9 and a fixed flushing device 10. The high-temperature fluid outlet constriction pipe 7 is also provided with a high pressure Flushing device 1 1. Soot blower 1 2 and fixed flushing device 1 3. During the operation of the plant, the dust blowers 9, 12 are used to remove the dust adhering to the surface of the heat transfer element 3 regularly, and when the plant is stopped, the fixed high-pressure washing device 8. 11 1 can also be rinsed during operation. The above-mentioned high-temperature fluid outlet tapered conduit 7 is connected to the conduit 14 below, and further below it is connected to the rinse water drain funnel 15. A funnel drain port 1 6 and a drain valve 1 7 are arranged at the bottom of this intermediate washing water drain funnel 15. A backwash pipe 18 is connected between these funnel drain port 16 and the drain valve 17. 1 9 It is a backwash valve. An overflow drain port 20 and a drain valve 21 are arranged above the rinsing hopper 15 for flushing water. Between the overflow drain port 20 and the drain valve 2 1, a pipe for backwash water 2 2 »2 3 is a backwash valve. Next, the function of the device of the above embodiment will be described. First, before the flushing starts, with the drain valves 17 and 21 and the backwash valve 19 closed, open the backwash valve 2 3 to backwash and remove dust and the like clogged inside the overflow drain 2 0 . Then open the above drain valve 21, and the paper size closed at drain valve 17 is applicable to the Chinese National Standard (CNS) A4 regulation 2 丨 x_297 Gongqing) 1 6 (Please read the precautions on the back before filling in this purchase ) Order 311983 A7 B7 Printed by the Staff Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economy V. Description of the invention (4) Open the backwash valve 1 9 to block the dust inside the drain port 16 of the hopper 15 for flushing water drainage, etc. Backwash to remove. Further inject water into the above-mentioned flushing water drain funnel 15 and confirm that the over-drain will overflow from the overflow drain through the side flow gauge 25. After the above-mentioned drainage pit 24 flows in, close the backwash valve 1 9 to drain Valve 1 7 opens in one go for drainage. , Repeat the above operation 2 ~ 3 times, after confirming that the drainage is carried out smoothly, move to the high pressure washing device 10, 13. Even in the flushing using these high-pressure flushing devices 10 and 13, since the initial stage of flushing, the drain port 16 may be blocked due to the adhesion of dust or the like on the wall surface of the duct 14 on the heat transfer element, so the above should be performed regularly Operation》 In addition, in Figure 2, 27 series is high-pressure flushing water piping connected to a high-pressure jet pump (not shown), 28 series is steam piping, 29 is flushing water piping, and 30 is cleaning.
