Description

Technical Field

[0001] The utility model relates to the technical field of chemical production, and particularly relates to a special equipment for coke remover. Background Art

[0002] At present, in the process of burning, coal-fired boilers, especially large industrial coal-fired boilers, inevitably cause coking on the furnace wall surface. Especially when using inferior coal or high-sulfur coal, coking is more serious. If the coking on the inner wall of the boiler is not removed, it will endanger the safe operation of the boiler. Although various anti-coking agents are added to the coal, it is still impossible to completely avoid the coking phenomenon. The coking on the furnace wall surface has a strong adhesion between the coke block and the furnace wall surface, and usually cannot fall off by its own gravity. External force must be used to remove it, and a relatively large external force is required to flush it out to make it fall off. During manual coke removal, due to the large volume of the coke removal equipment and the difficulty in moving it, the labor intensity of workers is increased. Content of the Utility Model

[0003] The utility model provides a special equipment for coke remover, which can meet the mobile operation between multiple devices, maintain the cleanliness of the on-site operation, and at the same time, the equipment is simple to operate, can accurately control the flow rate of air and liquid, and uses the on-site gas source to connect the equipment, simplifying the driving problem of the equipment.

[0004] In order to achieve the above object, the utility model provides the following technical solution: a special equipment for coke remover, which includes: a pressure tank, the bottom of the pressure tank is provided with casters, and the top is provided with a liquid inlet pipe, a liquid outlet pipe, and an air inlet pipe that communicate with the inside of the pressure tank; the bottom end of the liquid outlet pipe extends towards the bottom of the pressure tank; the liquid inlet pipe, the liquid outlet pipe, and the air inlet pipe are respectively provided with a liquid inlet valve, a liquid outlet valve, and an air inlet valve; a spray pipe, one end of the spray pipe is connected to the liquid outlet valve through a high-pressure hose, and the other end is provided with a nozzle.

[0005] Preferably, a liquid storage tank is arranged above the pressure tank, the liquid inlet valve is connected to the bottom of the liquid storage tank through a vertical rigid pipe, and the top of the liquid storage tank is provided with an upper cover.

[0006] Preferably, the top of the pressure tank is provided with a pressure gauge, a safety valve, and a gas discharge pipe that communicate with the inside, and the gas discharge pipe is provided with a gas discharge valve.

[0007] Preferably, the spray pipe is connected to the high-pressure hose through a tee, and the axis of the nozzle forms a 45-degree angle with the axis of the spray pipe.

[0008] Preferably, a liquid level gauge is arranged on one side of the pressure tank and communicates with the inside.

[0009] Preferably, handles are respectively arranged on both sides of the top of the pressure tank.

[0010] The beneficial effects of the present utility model are as follows: The miniaturization of the coke removal equipment is realized. During the working process, the pressure tank is used to hold the coke removal agent. By closing the liquid inlet valve and the liquid outlet valve and connecting the air inlet valve to a high-pressure gas source, the pressure tank is inflated, thereby increasing the internal pressure of the pressure tank. When the liquid outlet valve is opened, the internal coke removal agent is sprayed out through the high-pressure hose and the nozzle of the spray pipe, so that it is convenient for workers to hold and perform coke removal operations inside the coal-fired boiler. At the same time, since casters are provided at the bottom of the pressure tank, it is convenient for workers to easily move the pressure tank through the handle, meeting the movement operations between multiple devices and maintaining the cleanliness of the on-site operation. At the same time, the equipment is simple to operate, can accurately control the flow of air and liquid, and uses the on-site gas source to connect the equipment, simplifying the driving problem of the equipment. In order to carry more coke removal agent, the coke removal agent can be poured into the liquid storage tank. When the coke removal agent in the pressure tank is exhausted, the staff opens the air release valve to release the pressure in the pressure tank, and then opens the liquid inlet valve to make the coke removal agent in the liquid storage tank leak into the pressure tank. During the liquid addition process, the staff can check the liquid level height of the coke removal agent in the pressure tank through the liquid level gauge. After the liquid addition is completed, the staff closes the liquid inlet valve and the air release valve again and represses the pressure tank to continue the coke removal operation. At the same time, during the operation process, the staff can understand the working condition air pressure of the equipment in real time through the pressure gauge. It can also be used for coke removal spraying operations together with additional raw materials or compressed air through the three-way joint, thereby increasing the coke removal force, and achieving a larger coke removal range through the inclined nozzle.

[0017] Through this setting, the miniaturization of the de-coking equipment is realized. During the working process, the pressure tank 1 is used to hold the de-coking agent. By closing the liquid inlet valve 6 and the liquid outlet valve 7 and connecting the air inlet valve 8 to a high-pressure gas source, the pressure tank 1 is inflated, thereby increasing the internal pressure of the pressure tank 1. When the liquid outlet valve is opened, the internal de-coking agent is sprayed out through the high-pressure hose 10 and the nozzle 11 of the spray pipe 9, so that it is convenient for workers to hold and perform de-coking operations inside the coal-fired boiler. At the same time, since casters 2 are provided at the bottom of the pressure tank 1, it is convenient for workers to easily move the pressure tank 1 through the handle 21, meet the moving operations between multiple devices, and maintain the cleanliness of the on-site operation. At the same time, the operation of this equipment is simple, the air flow and liquid flow can be accurately controlled, and the equipment is connected to the on-site gas source, simplifying the driving problem of the equipment.
