Description

Technical Field

[0001] The utility model relates to the technical field of soot blower protection, in particular to a protection device for a steam soot blower. Background Technique

[0002] A soot blower is a device used to remove ash deposited on the heating surface of a boiler. It is usually composed of components such as a soot blowing pipe and an operation valve. Generally, it is respectively arranged on the furnace walls of the boiler furnace, horizontal flue, and tail flue, etc. According to the structural type, there are several types such as gun type, rotary type, and telescopic type. According to the different media used, there are three types: air soot blower, steam soot blower, and hydraulic soot blower. The air soot blower uses the high-pressure air flow impact force of compressed air to blow off the ash on the heating surface and is commonly used in industrial boilers. The steam soot blower uses the high-speed jet impact force of superheated steam to remove the ash on the heating surface and is mostly applied to various power plant boilers.

[0003] According to a kind of intelligent protection device for a steam soot blower in a coal-fired boiler disclosed in the Chinese Patent Publication No. CN 219797232 U, the top of the shell of this device is fixedly communicated with an air inlet pipe, one side of the shell is fixedly communicated with an exhaust pipe, and a temperature sensor is arranged on the outer surface of the exhaust pipe. A nozzle assembly is arranged at one end of the exhaust pipe, and an annular cooling cavity is opened inside the exhaust pipe. Through the two groups of heat dissipation fins installed on the exhaust pipe in the utility model, the heat inside the exhaust pipe can be discharged, improving the self-cooling effect of the exhaust pipe, avoiding the high temperature of the exhaust pipe being inconvenient to dissipate, and thus easily causing the phenomenon of scalding to the staff. It has the function of automatic cooling, and through the setting of the cooling component, low-temperature gas can be injected into the cooling cavity, and through the low-temperature gas, the exhaust pipe can be quickly cooled, having a multiple cooling treatment function.

[0004] However, when the above device is in use, the heat dissipation fins enter the boiler along with the pipeline. When soot blowing is carried out, it is easy for ash to accumulate on the heat dissipation fins outside the pipeline. Then, after the soot blowing is completed, the heat dissipation effect is not good, making the device have certain limitations. Content of the Utility Model

[0005] The purpose of the utility model is to provide a protection device for a steam soot blower to solve the problem that when the above device is in use, the heat dissipation fins enter the boiler along with the pipeline. When soot blowing is carried out, it is easy for ash to accumulate on the heat dissipation fins outside the pipeline. Then, after the soot blowing is completed, the heat dissipation effect is not good, making the device have certain limitations as mentioned in the above background technique.

[0006] To solve the above technical problems, the utility model provides the following technical solution: A protection device for a steam soot blower, including a soot blowing pipe, a protection mechanism is arranged outside the soot blowing pipe, and a replacement mechanism is arranged outside the protection mechanism;

[0007] The exhaust pipe of the protection mechanism, a cooling chamber is provided inside the exhaust pipe, a connecting sleeve is fixedly connected to the outside of the exhaust pipe, an electric push rod is fixedly connected to the inside of the connecting sleeve, a protective sleeve is fixedly connected to the top of the electric push rod, heat dissipation fins are installed on the outer wall of the cooling chamber, and a cooling component is provided at one end of the cooling chamber.

[0008] Preferably, the cooling component includes a cooling pipe and a ventilation pipe, and a blower is installed at one end of the cooling pipe.

[0009] Preferably, one end of the cooling pipe is fixedly communicated with the cooling chamber, the ventilation pipe is fixedly communicated with the top of the cooling chamber, and valves are installed on the outsides of both the cooling pipe and the ventilation pipe.

[0010] Preferably, one end of the exhaust pipe is fixedly communicated with one end of the soot blowing pipe, and the connecting sleeve is arranged in a concave shape.

[0011] Preferably, the replacement mechanism includes a mounting seat, a connecting block is clamped on the top of the mounting seat, and a sealing gasket is installed at the bottom of the connecting block.

[0012] Preferably, the mounting seat is fixedly connected to the top of the exhaust pipe, and the inner side of the connecting block is fixedly connected to the outer wall of the heat dissipation fins.

[0013] Preferably, there are multiple mounting seats, and the multiple mounting seats are arranged in a linear array distribution.

[0014] Compared with the prior art, the beneficial effects achieved by the present utility model are as follows:

[0015] First, the present utility model makes the steam enter the exhaust pipe through the connection between the soot blowing pipe and the exhaust pipe, and then the steam can be ejected through the nozzle at one end of the exhaust pipe for soot blowing. At this time, the protective sleeve is sleeved outside the heat dissipation fins. When the exhaust pipe enters the boiler, ash will not accumulate on the heat dissipation fins, protecting the heat dissipation fins and avoiding affecting the heat dissipation effect. After soot blowing, by starting the electric push rod in the connecting sleeve, the protective sleeve is pushed by the electric push rod, and then one end of the heat dissipation fins located outside the exhaust pipe is exposed. Then the other end of the heat dissipation fins contacts the surface of the cooling chamber, so that the temperature in the exhaust pipe is discharged through the heat dissipation fins. Then, by opening the valves outside the cooling pipe and the ventilation pipe, blowing air through the blower, and inputting the cooled air into the interior of the cooling chamber through the cooling pipe, and then dissipating the heat through the ventilation pipe, the heat dissipation operation is completed, achieving the effect of protecting the staff from scalding.

[0016] Second, the utility model is fixedly connected to the outer wall of the heat dissipation fins through the connecting block. By clamping the connecting block into the interior of the mounting seat and using a gasket to seal the connection, heat loss is avoided when the exhaust pipe conveys steam. After the connecting block is clamped into the mounting seat, one end of the heat dissipation fins contacts the surface of the cooling chamber, and heat dissipation can then begin. When the protective sleeve descends, it can be clamped to the mounting seat, thereby forming a sealed space to better protect the internal heat dissipation fins. Through the clamping method, it is convenient to replace the heat dissipation fins after damage, achieving the effect of being easy to disassemble and replace. Description of the Drawings

[0027] The cooling component 27 includes a cooling pipe 28 and a ventilation pipe 29. A blower 201 is installed at one end of the cooling pipe 28.

[0028] One end of the cooling pipe 28 is fixedly communicated with the cooling chamber 22. The ventilation pipe 29 is fixedly communicated at the top of the cooling chamber 22. Valves are installed on the outside of both the cooling pipe 28 and the ventilation pipe 29.

[0029] One end of the exhaust pipe 21 is fixedly communicated with one end of the soot blowing pipe 1. The connecting sleeve 23 is arranged in a concave shape.

[0030] Through the above technical solution, at this time, the soot blowing pipe 1 is communicated with the exhaust pipe 21, so that steam can enter the exhaust pipe 21. Then, the steam can be ejected through the nozzle at one end of the exhaust pipe 21 for soot blowing. At this time, the protective sleeve 25 is sleeved outside the heat dissipation fins 26. When the exhaust pipe 21 enters the boiler, ash will not accumulate on the heat dissipation fins 26, protecting the heat dissipation fins 26 and avoiding affecting the heat dissipation effect. After the soot blowing is completed, by starting the electric push rod 24 in the connecting sleeve 23, the protective sleeve 25 is pushed by the electric push rod 24, so that one end of the heat dissipation fins 26 located outside the exhaust pipe 21 is exposed.
