Description

Technical Field

[0001] The utility model belongs to the technical field related to furfural slag treatment, and particularly relates to a slag shed demisting device. Background Art

[0002] Furfural slag shed is the key temporary storage place for the biomass "formaldehyde electricity and heat" integrated project. It is the heart of maintaining the long-term stable operation of the biomass cogeneration project. A good environment in the furfural slag shed is the basis for the stable operation of the biomass boiler. In order to create a good slag shed environment to ensure the uniformity of biomass boiler fuel mixing and provide high-quality food for the boiler, the moisture in the furfural slag evaporates in the slag shed to form water mist in the winter due to the decrease in air humidity, causing condensation on the top of the slag shed, affecting work, but it still has the following disadvantages in actual use:

[0003] When the slag shed demisting device is working, the air in the slag shed is directly extracted by the exhaust device, which will cause great pollution. Therefore, it needs to be extracted to the external treatment equipment. However, due to site reasons, the external air treatment equipment is installed in different locations. When it is working, the installation flexibility is poor and it is inconvenient to use.

[0004] When the slag shed demisting device is working, the water content in the mist is relatively high. When passing through the fan, the mist condenses on the fan, which will cause the fan to wear out faster, and the fan is easily damaged, and its durability during operation is poor. Utility Model Content

[0005] The utility model aims to provide a slag shed demisting device, which solves the problems that the installation flexibility of the slag shed demisting device is not high enough when it is working, and the humidity of the air is high when it is extracted, which makes the fan easily damaged when it passes through the fan by arranging an air suction shell, an air transmission pipeline, a transfer box and an output shell.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model discloses a demisting device for a slag shed, comprising an air intake shell, an air delivery pipeline, a transfer box and an output shell, wherein a transfer box is arranged on one side of the air intake shell, and a plurality of air delivery pipelines parallel to each other are arranged between the transfer box and the air intake shell, wherein the air delivery pipeline comprises a transfer pipe and a bellows, both ends of the transfer pipe are fixedly connected with the bellows, an output shell is arranged on the outer side of one end of the transfer box, and a liquid outlet pipe is fixedly connected with the bottom of the transfer box. When working, when negative pressure is generated in the air intake shell, the mist in the slag shed is sucked in together with the air, and transported to the air delivery pipeline, and then transported to the transfer box through the air delivery pipeline, and when the mist passes through the air delivery pipeline, it is condensed on the inner wall of the transfer pipe, transported to the transfer box, and then outputted through the liquid outlet pipe at the bottom of the transfer box, and finally transported to the output shell through the fixed shell.

[0008] Furthermore, a protective net is embedded and fixed on the side of the air intake shell away from the gas pipeline, and a plurality of connecting holes are opened on the side of the air intake shell close to the gas pipeline. The gas pipelines correspond to the connecting holes one by one, and the air intake shell prevents debris from being discharged through the protective net.

[0009] Furthermore, the gas supply pipeline also includes a fixed pipe, and the ends of the two corrugated pipes that are away from each other are fixedly connected with a fixed pipe. The fixed pipe close to the intake shell is fixed on the intake shell outside the connecting hole, and the gas supply pipeline is connected with the intake shell and the transfer box through the fixed pipe.

[0010] Furthermore, a second connecting hole is provided on one side of the transfer box close to the air intake shell corresponding to the position of the first connecting hole. A fixed pipe close to the transfer box is fixed on the transfer box outside the second connecting hole. The transfer box is connected to the fixed pipe through the second connecting hole.

[0011] Furthermore, the end of the transfer box close to the output shell is fixedly connected to a side tube, the end of the side tube away from the transfer box is fixedly connected to a fixed shell, the fixed shell is fixedly connected to the output shell, the transfer box is connected to the fixed shell through the side tube, and is connected to the output shell through the fixed shell.

[0012] Furthermore, a fixing frame is fixed to one end of the inner wall of the output shell close to the fixed shell, an output fan is fixed in the fixing frame, and an air outlet pipe is fixedly connected to one end of the output shell away from the fixed shell. When the output shell is working, the output fan is connected through the fixing frame, and the air is discharged to the air processing equipment through the air outlet pipe.

[0013] The utility model has the following beneficial effects:

[0014] The utility model solves the problem that the installation flexibility of the slag shed demisting device is not high enough when it is working by arranging an air suction shell, an air transmission pipeline and a transfer box. The air suction shell is arranged in the slag shed, and the air transmission pipeline extends out of the slag shed. By bending the transfer pipe, the bellows and the fixed pipe, the transfer box is located at a suitable installation position with the cooperation of the bellows, so that the installation flexibility of the slag shed demisting device when working is higher.

[0015] The utility model solves the problem that the humidity of air extracted by the demisting device of the slag shed is relatively high and the fan is easily damaged by passing through the fan by arranging an air suction shell, an air transmission pipeline, a transfer box and an output shell. The output fan generates negative pressure in the fixed shell when the output fan is working. After the negative pressure is generated in the fixed shell, the negative pressure is generated in the air washing shell, and a mixture of mist and air in the slag shed is sucked in, and after being transported to the transfer box through the air transmission pipeline, condensed water and air are transported to the side pipe, transported to the fixed shell through the side pipe, and transported to the air outlet pipe through the fixed shell for output, so that the humidity of air extracted by the demisting device of the slag shed is lower when it is working, thereby preventing damage to the fan.
