Description

Technical Field

[0001] The utility model relates to the technical field of boilers, in particular to a boiler heating and ventilation cyclone cleaner. Background Art

[0002] A boiler is a device that uses the heat energy released by fuel combustion or other heat energy to heat water or other fluids to certain parameters. As an important thermal energy equipment, boilers are widely used in many fields such as electricity, chemical industry, steel, papermaking, etc. During the combustion and heat transfer process of the boiler, wastewater containing impurities and particulate matter will be generated. In order to effectively remove impurities and particulate matter in the water, a boiler HVAC decontamination device is required to decontaminate the boiler HVAC system to ensure the normal operation of the boiler HVAC system.

[0003] However, the existing boiler HVAC cyclone cleaner lacks the structure of using spiral guide grooves to force the wastewater to form a rotating water flow, and does not have the function of secondary filtration of the wastewater. It cannot prevent impurities and particulate matter from being deposited inside the boiler, resulting in poor heat transfer efficiency and operating efficiency of the boiler. For this reason, we propose a boiler HVAC cyclone cleaner. Utility Model Content

[0004] In response to the problems in the existing technology, the utility model provides a boiler HVAC cyclone cleaner. The new boiler HVAC cyclone cleaner has a structure that uses a spiral guide groove to cause the wastewater to form a rotating water flow, and can perform secondary filtration on the wastewater, thereby preventing impurities and particulate matter from being deposited inside the boiler, thereby effectively improving the heat transfer efficiency and operating efficiency of the boiler.

[0005] The technical solution adopted by the utility model to solve its technical problems is a boiler HVAC cyclone decontaminator, comprising a water inlet channel, an impurity collection channel, a No. 1 filter screen, a spiral guide groove, a No. 1 sealing gasket, a No. 2 sealing gasket and a No. 2 filter screen, wherein the bottom of the water inlet channel is connected to the impurity collection channel, the inner side of the impurity collection channel is provided with a spiral guide groove, the lower end of the impurity collection channel is provided with a No. 1 discharge channel, a mounting shell is provided between the top of the No. 1 discharge channel and the bottom of the impurity collection channel, and the No. 1 filter screen is installed inside the mounting shell;

[0006] The bottom of the No. 1 discharge channel is connected to a No. 1 flange, the lower end of the No. 1 discharge channel is provided with a No. 2 discharge channel, the top of the No. 2 discharge channel is connected to a No. 2 flange, and a No. 2 filter is provided between the No. 2 flange and the No. 1 flange.

[0007] By adopting the above technical solution, wastewater flows through the spiral guide groove to form a rotating water flow. Impurities and particulate matter in the wastewater are thrown toward the inner wall of the impurity collection channel due to the centrifugal force, and settle along the inner wall of the impurity collection channel to the bottom of the impurity collection channel. The No. 1 filter can filter the impurities and particulate matter in the wastewater, thereby achieving the purpose of preliminary filtration of impurities and particulate matter in the wastewater.

[0008] When the wastewater flows through the No. 2 filter, the No. 2 filter can filter the impurities and particulate matter remaining in the wastewater to achieve the purpose of further filtration, which can effectively reduce the impurity content in the wastewater.

[0009] Specifically, a No. 1 sealing gasket and a No. 2 sealing gasket are respectively provided on the top and bottom of the No. 2 filter screen, a No. 2 bolt is provided on the outside of the No. 1 flange, and a nut is provided on the outside of the No. 2 flange.

[0010] By adopting the above technical solution, personnel can put the nut on the outer periphery of the end of the No. 2 bolt to firmly set the No. 2 filter between the No. 1 flange and the No. 2 flange.

[0011] Specifically, the outer sides of the No. 1 flange, the No. 2 flange, the No. 1 sealing gasket, the No. 2 sealing gasket and the No. 2 filter are all provided with No. 3 bolt holes.

[0012] By adopting the above technical solution, the No. 3 bolt hole facilitates the No. 2 bolt to pass through the No. 1 flange, the No. 2 flange, the No. 1 sealing gasket, the No. 2 sealing gasket and the No. 2 filter screen.

[0013] Specifically, the No. 1 sealing gasket and the No. 2 sealing gasket are both made of silicone material.

[0014] Specifically, No. 1 bolts are provided on all four sides of the mounting shell by opening No. 1 bolt holes, and No. 2 bolt holes are opened on all four sides of the No. 1 filter.

[0015] Beneficial effects of the utility model:

[0016] (1) The utility model describes a boiler HVAC cyclone decontamination device, in which wastewater flows through a spiral guide groove to form a rotating water flow. Impurities and particulate matter in the wastewater are thrown toward the inner wall of the impurity collection channel due to the action of centrifugal force, and settle along the inner wall of the impurity collection channel to the bottom of the impurity collection channel. The No. 1 filter can filter the impurities and particulate matter in the wastewater, thereby achieving the purpose of preliminary filtration of impurities and particulate matter in the wastewater.

[0027] In use, the wastewater flows through the spiral guide groove 7, and a rotating water flow can be formed. The impurities and particles in the wastewater are thrown to the inner wall of the impurity collection channel 2 due to the centrifugal force, and then settle to the bottom of the impurity collection channel 2 along the inner wall of the impurity collection channel 2. The first filter screen 8 can filter the impurities and particles in the wastewater, thereby achieving the purpose of preliminarily filtering the impurities and particles in the wastewater.

[0028] When the wastewater flows through the second filter screen 13, the second filter screen 13 can filter the residual impurities and particles in the wastewater, thereby achieving the purpose of further filtering and effectively reducing the impurity content in the wastewater.

[0029] As shown in Figure 4 , the top and bottom of the second filter screen 13 are respectively provided with a first sealing gasket 11 and a second sealing gasket 12, the outer side of the first flange plate 9 is provided with a second bolt 14, and the outer side of the second flange plate 10 is provided with a nut 15.

[0030] In use, the personnel can set the nut 15 on the periphery of the end of the second bolt 14, so as to stably set the second filter screen 13 between the first flange plate 9 and the second flange plate 10.

[0031] As shown in Figure 4 , the outer sides of the first flange plate 9, the second flange plate 10, the first sealing gasket 11, the second sealing gasket 12, and the second filter screen 13 are all provided with third bolt holes 16.

[0032] In use, the third bolt holes 16 facilitate the second bolt 14 to pass through the first flange plate 9, the second flange plate 10, the first sealing gasket 11, the second sealing gasket 12, and the second filter screen 13.

[0033] As shown in Figure 4 , the first sealing gasket 11 and the second sealing gasket 12 are both made of silica gel material.

[0037] When the utility model is in use, personnel introduce wastewater generated after boiler combustion into the impurity collection channel 2 through the water inlet channel 1. The wastewater flows through the spiral guide groove 7 to form a rotating water flow. During the rotation process, impurities and particulate matter in the wastewater are thrown toward the inner wall of the impurity collection channel 2 due to the action of centrifugal force, and settle along the inner wall of the impurity collection channel 2 to the bottom of the impurity collection channel 2. At this time, the first filter screen 8 can perform preliminary filtration of impurities and particulate matter in the wastewater;
