Description

Technical Field

[0001] The utility model relates to a dry steel belt machine device with auxiliary water spraying. Background Art

[0002] At present, dry slag conveyors are becoming more and more common in power plants. Compared with the wet slag discharge used in power plants before, the main advantages of dry slag discharge are that the dry slag conveyor is safe and environmentally friendly. It cools the slag through natural wind and does not require a large amount of water, saving water resources. Secondly, it has high safety and relatively high safety for disturbing the furnace combustion and local coke knocking. However, it also has disadvantages. It is more suitable for boilers that are not prone to coking. When the slag volume is large, it is more difficult to squeeze the slag and it is not easy to crush. Since boiler coking is inevitable and the coal types vary, the shapes of the coke slag produced by combustion are also inconsistent. When large red soft coke drops from the bottom of the furnace for dry slag discharge, the cooling time is not sufficient, the soft coke cannot be crushed back and forth, and after being squeezed into a ball and cooled, it becomes a reef and is very difficult to break. Moreover, after the large broken pieces enter the slag crusher, they are not easy to break and easily accumulate in the upper space of the slag crusher, resulting in poor slag discharge of the steel belt machine and jamming and tripping back to the cleaning chain. And as the automation level of power plants is getting higher and higher, the on-duty production personnel are getting more and more streamlined, and the production pressure of front-line production personnel is also getting greater and greater. At the same time, it increases the labor intensity and reduces the production efficiency. Summary of the Invention

[0003] The purpose of the utility model is to provide a dry steel belt machine device with auxiliary water spraying.

[0004] The above purpose is achieved by the following technical solutions:

[0005] A dry steel belt machine device with auxiliary water spraying, which comprises: a water pump, a front inlet pipeline and a rear inlet pipeline. The front inlet pipeline and the rear inlet pipeline are connected to the water pump, and an inlet manual valve A is installed on the front inlet pipeline, and an inlet manual valve B is installed on the rear inlet pipeline. The water pump is connected with a water pump outlet header pipe, and two small pipes are led out from the water pump outlet header pipe;

[0006] The small pipes pass through the small holes at the slopes on both sides of the furnace bottom slag well, and the outlet ends of the small pipes are connected with nozzles. An electromagnetic valve and a small pipe manual valve are respectively installed on each small pipe.

[0007] For the dry steel belt machine device with auxiliary water spraying, the nozzles are installed in a ring structure above the slag well extrusion head, and openings are correspondingly arranged above each slag well extrusion head, and one nozzle is installed in each opening.

[0008] For the dry steel belt machine device with auxiliary water spraying, smooth steel plates are installed on the two slope sections on both sides in the slag well, and the angle between the smooth steel plates and the horizontal plane is greater than 60 degrees.

[0009] The described dry steel belt machine device with auxiliary water spraying, where the nozzle is installed in the opening arranged above the slag well extrusion head. Beneficial effects

[0010] 1. The utility model optimizes the dry slag discharging device system, improves the slag extrusion efficiency, and at the same time reduces the work pressure of production personnel, releasing more physical and mental energy to complete other tasks.

[0011] 2. In order to make up for the deficiencies of the prior art, the utility model provides a dry steel belt machine device with auxiliary water spraying for cooling to quickly break slag blocks. This method mainly combines the advantages of wet slag discharging and dry slag discharging, learning from each other's strengths and making up for each other's weaknesses, and systematically optimizing the dry slag discharging machine device.

[0012] 3. When the unit of the utility model operates normally, according to the situation of coke dropping at the furnace bottom, the operator manually inputs. When it is found that there are large red coke blocks dropping at the furnace bottom, adjust the position of the nozzle, open the water spraying solenoid valve, spray water for cooling, and rapidly cool the furnace slag. After crushing, the small slag blocks are then extruded.

[0013] 4. The utility model covers a smooth steel plate on the surface of the castable on the slope of the slag well. The slope angle with the horizontal angle > 60° is preferred. When slag drops, the slag blocks automatically slide down to the slag well, facilitating slag extrusion. No coke slag will accumulate and form a bridge on the slope section. When coke drops, it freely slides down to the steel belt machine. It solves the problem that it is easy to hang coke and accumulate on the slope section of the slag well - that is, due to the arrangement of castable here, after long-term operation, the surface is uneven with many burrs, and there is a certain horizontal angle, which is prone to generate hanging coke points, and the hanging coke accumulation cannot be fed into the steel belt machine.

The described dry steel belt machine device with auxiliary water spraying, wherein the nozzles are installed in the openings arranged above the slag well extrusion head. Embodiment

[0019] A dry steel belt machine device with auxiliary water spraying includes a water spraying pipeline and corresponding auxiliary equipment. An inlet manual valve is installed on the inlet pipeline. There is a pipeline connected to the desulfurized waste water before the inlet manual valve, and an inlet pipeline after the inlet manual valve. The pipeline is connected to a water pump. Two small pipes are led out from the outlet header pipe of the water pump. Manual valves and solenoid valve devices are installed on these small pipes. After being connected to the small pipes, they are led to the slopes of the two side walls of the furnace bottom slag well. Small holes (matched with the pipe diameter) are opened at the high points of the slope sections. The outlet ends of the small pipes are equipped with nozzle devices and installed at the openings. At the same time, a camera is installed at the nozzle of the small pipe, and the picture is led to the centralized control room. The specific adjustable range of the nozzle angle is used to aim at the slag blocks at the furnace bottom.

[0020] A supplementary cooling device is added to the dry slag discharging device. The self-air cooling device is not sufficient for cooling and cannot crush. For the red and soft coking blocks, a cooling water system device is arranged in a circle above the slag well extrusion head, that is, openings are correspondingly arranged above each extrusion head, and one nozzle is arranged. The nozzle is fixed downward at a certain angle and aims at the coking blocks at the corresponding position of the furnace bottom. An electromagnetic valve and a manual valve are installed in front of each nozzle branch pipe and connected to the water inlet header pipe. The water source can be taken from the desulfurized waste water. When the operators on the control panel find that large red and soft coking blocks fall at the furnace bottom, the electromagnetic valve at the corresponding position is opened to spray water for cooling the coking slag. The coking slag cracks sharply into small slag blocks under the cold, which is convenient for extrusion and crushing. At the same time, it also solves the problem that the desulfurized waste water cannot be utilized to a certain extent.
