Description

Technical Field

[0001] The utility model relates to the technical field of economizers, in particular to a novel refined small R economizer. Background Art

[0002] Heat pipe economizer is an essential component of modern boilers. Its function is to use the heat of the flue gas at the tail end of the boiler to heat the boiler feed water and reduce the heat loss of the flue gas. The heat pipe economizer can recover the heat of flue gas. The recovered heat can be used to heat water for boiler replenishment water and domestic water as needed, or to heat air for boiler combustion air or drying materials, or the generated hot water can be used for production, saving fuel costs, reducing production costs, and reducing exhaust gas emissions. It has the functions of energy saving and environmental protection. A Chinese patent discloses an economizer (authorization announcement number CN219775710U), but the connecting end of the serpentine tube extends to the outside of the economizer body through the extension through hole, and then the bolt is inserted into the corresponding locking slot through the installation card hole to complete the locking of the disassembly plate. After the connecting ends of the two ends of the serpentine tube are connected to the connecting pipes on both sides of the economizer body, the external cooling water passes through the serpentine tube and enters the economizer body to circulate inside, absorbing the heat of the flue gas passing through the serpentine tube. The installation frame that is convenient for disassembly and assembly can make it easier to replace and repair the serpentine tube when it is damaged after long-term use. However, the above-mentioned economizer is not equipped with an alarm device when working, and cannot give a real-time alarm according to the pressure environment inside the economizer, which will cause safety hazards. Therefore, a new type of refined small R economizer is provided to solve the problems raised in the above-mentioned background technology. Utility Model Content

[0003] The purpose of the utility model is to provide a novel refined small R economizer to solve the problems raised in the above background technology.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] A novel refined small R economizer comprises an economizer shell, wherein a plurality of interpenetrating spiral finned tubes are arranged inside the economizer shell, a water inlet pipe and a water outlet pipe are fixed and interpenetratingly connected on the spiral finned tubes, an air inlet pipe and an air outlet pipe are respectively arranged on both sides of the economizer shell, a pressure exhaust pipe is penetrated through the upper side of the economizer shell, one end of the pressure exhaust pipe located inside the economizer shell is fixed and interpenetratingly connected with an air collecting hood, a sliding pipe is slidably connected inside the pressure exhaust pipe, a plurality of exhaust holes are opened on the side of the sliding pipe, the exhaust holes are interpenetrating with the air collecting hood, a negative electrode block is installed on the upper side of the sliding pipe, a mounting plate is arranged on one side of the pressure exhaust pipe, the mounting plate is fixedly connected to the economizer shell, a positive electrode block is installed on the lower side of the mounting plate, and an alarm is installed on the mounting plate.

[0006] As a further solution of the utility model: wherein, a spiral fin tube is fixedly connected to the inside of the economizer shell, and the spiral fin tube is installed inside a mounting frame, and a plurality of ventilation grooves are opened on the mounting frame.

[0007] As a further solution of the utility model: wherein, the water inlet pipe and the water outlet pipe penetrate the economizer shell and extend to the outside, and valves are installed on the water inlet pipe and the water outlet pipe.

[0008] As a further solution of the utility model: wherein, the air outlet pipe is fixed and connected to the economizer housing, one side of the air inlet pipe is fixed and connected to a dust removal box, a filter is installed inside the dust removal box, and multiple exhaust pipes are arranged on the upper side of the filter, and both ends of the exhaust pipes are respectively fixed and connected to the economizer housing and the dust removal box.

[0009] As a further solution of the utility model: wherein, a stretching rod is arranged through the interior of the dust removal box, a round plate is fixedly connected to the tail end of the stretching rod, a spring is sleeved on the stretching rod, and a box cover is bolted to the bottom side of the dust removal box.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] Through the provided air inlet pipe and exhaust pipe, flue gas can be injected into the economizer shell and then discharged through the outlet pipe. When there is too much smoke inside the economizer shell and the exhaust efficiency of the outlet pipe is slow, the smoke accumulates inside the economizer shell and the internal pressure of the economizer shell will increase. The internal pressure pushes the sliding pipe to move inside the pressure relief pipe, so that the exhaust hole leaks from the inside of the pressure relief pipe, and some high-pressure flue gas can be discharged. When the sliding block moves up, it will drive the negative electrode block to move up. When the negative electrode block and the positive electrode block are connected, the alarm will be energized and turned on to alarm, thereby reminding the staff that the pressure inside the economizer shell is too high.

[0020] The medium to be heated is injected into the spiral fin tube 201 through the water inlet pipe 202 , and the heated medium is discharged through the water outlet pipe 203 .

[0021] An air inlet pipe 302 and an air outlet pipe 308 are respectively provided on both sides of the economizer shell 1. A pressure exhaust pipe 4 is penetrated through the upper side of the economizer shell 1. The pressure exhaust pipe 4 is located at one end inside the economizer shell 1 and is fixed and connected with an air collecting hood 401. A sliding pipe 402 is slidably connected inside the pressure exhaust pipe 4. A plurality of exhaust holes 407 are opened on the side of the sliding pipe 402, and the exhaust holes 407 are connected with the air collecting hood 401.

[0022] The accumulation of flue gas inside the economizer shell 1 will increase the internal pressure of the economizer shell 1. The internal pressure pushes the sliding tube 402 to move inside the pressure relief pipe 4, so that the exhaust hole 407 leaks from the inside of the pressure relief pipe 4, and some high-pressure flue gas can be discharged.

[0023] A negative electrode block 403 is installed on the upper side of the sliding tube 402, a mounting plate 404 is provided on one side of the pressure relief pipe 4, the mounting plate 404 is fixedly connected to the economizer casing 1, a positive electrode block 405 is installed on the lower side of the mounting plate 404, an alarm 406 is installed on the mounting plate 404, the positive electrode block 405 and the negative electrode block 403 are coaxially arranged, and the positive electrode block 405 and the negative electrode block 403 are both electrically connected to the alarm 406.

[0024] Preferably, the economizer shell 1 is fixedly connected with a spiral fin tube 201 , and the spiral fin tube 201 is installed inside the mounting frame 2 , and a plurality of ventilation grooves 204 are provided on the mounting frame 2 .

[0025] The ventilation grooves 204 can make the flue gas float inside the economizer shell 1, and can heat the spiral fin tubes 201 at multiple angles.

[0026] Preferably, the air outlet pipe 308 is fixed and connected to the economizer housing 1, and a dust removal box 3 is fixed and connected to one side of the air inlet pipe 302. A filter screen 305 is installed inside the dust removal box 3, and multiple exhaust pipes 303 are arranged on the upper side of the filter screen 305. Both ends of the exhaust pipes 303 are respectively fixed and connected to the economizer housing 1 and the dust removal box 3.

[0027] The filter 305 can filter the flue gas entering the economizer housing 1 to prevent a large amount of soot in the flue gas from accumulating inside the economizer housing 1 .

[0028] Preferably, a stretching rod 304 is provided through the interior of the dust removal box 3, a round plate 306 is fixedly connected to the tail end of the stretching rod 304, a spring 307 is sleeved on the stretching rod 304, and a box cover 301 is bolted to the bottom side of the dust removal box 3.

[0030] Working principle: Flue gas can be injected into the economizer shell 1 through the set air inlet pipe 302 and exhaust pipe 303, and then discharged through the air outlet pipe 308. When there is too much flue gas in the economizer shell 1 and the exhaust efficiency of the air outlet pipe 308 is slow, the flue gas accumulates inside the economizer shell 1 and the internal pressure of the economizer shell 1 increases. The internal pressure pushes the sliding pipe 402 to move inside the pressure exhaust pipe 4, so that the exhaust hole 407 leaks from the pressure exhaust pipe 4, and some high-pressure flue gas can be discharged. When the sliding pipe 402 moves up, it will drive the negative electrode block 403 to move up. When the negative electrode block 403 and the positive electrode block 405 are connected, the alarm 406 will be energized and turned on to alarm, thereby reminding the staff that the internal pressure of the economizer shell 1 is too high.
