Description

Technical Field

[0001] The utility model relates to the technical field of waste gas flow detection, in particular to a waste gas emission detection device. Background Art

[0002] Waste gas is toxic and harmful gas discharged by humans in the process of production and life, including industrial waste gas, domestic waste gas, traffic waste gas and agricultural waste gas. In order to avoid direct waste gas discharge and pollution to the environment, the waste gas usually needs to be purified before it is discharged. Before purifying the waste gas, the emission flow rate of the waste gas needs to be detected to facilitate the adjustment of the waste gas purification plan.

[0003] In the prior art, the device for detecting the exhaust gas emission generally includes a connecting pipe and a flow meter. The connecting pipe is located at the end of the pipeline and is connected to the pipeline. The flow meter is connected to the connecting pipe, and the detection probe of the flow meter is located in the connecting pipe. During detection, the exhaust gas in the pipeline enters the connecting pipe, and the detection probe can detect the exhaust gas emission in the connecting pipe, and the flow meter can display the detection value. However, in the above scheme, since some exhaust gas may contain dust, the dust may adhere to the surface of the detection probe when passing through the connecting pipe. When the detection probe surface is adhered to dust, its sensitivity may be affected, thereby causing inaccurate detection results. Utility Model Content

[0004] The utility model aims to provide an exhaust gas emission detection device, which can reduce dust in the exhaust gas and avoid the dust from affecting the detection result.

[0005] To achieve the above-mentioned purpose, an exhaust gas emission detection device is provided, which includes: a filter component, the filter component includes a filter shell, and an air inlet pipe is arranged at one end of the filter shell; a purification component, the purification component includes a purification shell, a connecting pipe, a pipe head and a diversion pipe, the pipe head and the diversion pipe are both located in the purification shell, one end of the connecting pipe is passed through the top of the purification shell and is connected with the pipe head, the other end of the connecting pipe is connected with the other end of the filter shell, a plurality of diversion pipes are arranged at the bottom of the pipe head, and air holes are opened on the plurality of diversion pipes, an air outlet pipe is arranged at the top of the purification shell, and one end of the air outlet pipe is connected with the purification shell; a flow meter, the flow meter is connected with the air outlet pipe; a silencer component, the silencer component is connected with the other end of the air outlet pipe.

[0006] The working principle and effect of the above scheme: the device is suitable for exhaust gas in which toxic and harmful substances are insoluble in water; when using the detection device to detect the emission of exhaust gas, water is placed in the purification shell, the diverter pipe is located in the water, and the exhaust gas enters the filter shell from the air inlet pipe. The filter shell can filter floating objects in the exhaust gas, and the exhaust gas filtered by the filter shell enters the pipe head along the connecting pipe, and the exhaust gas in the pipe head enters the diverter pipe and overflows from the air hole. The exhaust gas overflowing from the air hole enters the water and floats upward in the water. During the process of the exhaust gas floating on the water, the dust in the exhaust gas is dissolved in the water. After the exhaust gas floats up, it reaches the top of the inner cavity of the purification shell. Further, the exhaust gas is discharged after passing through the exhaust pipe and the silencer assembly; the detection probe of the flow meter is located in the exhaust pipe. When the exhaust gas flows through the exhaust pipe, the flow meter can measure the emission of the exhaust gas.

[0007] By setting a purification shell and setting water in the purification shell, when the exhaust gas passes through the purification shell, the dust in the exhaust gas can be dissolved in water, thereby reducing the dust in the exhaust gas. The exhaust gas treated by the purification shell enters the exhaust pipe for detection. When the flow meter measures the emission of the exhaust gas, the dust content in the exhaust gas is less, thereby avoiding dust adhering to the detection probe and affecting the detection result.

[0008] In some embodiments, a demisting plate is disposed at the top of the inner cavity of the purification shell at the inlet of the air outlet pipe to reduce the water vapor content of the exhaust gas flowing into the air outlet pipe.

The motor is located on the outer bottom surface of the purification shell, and the rotating shaft and the stirring blade are both located inside the purification shell. One end of the rotating shaft is transmission-connected to the motor, and the other end of the rotating shaft is fixedly connected to the stirring blade.

[0010] When the stirring assembly is working, the motor is started, and the motor drives the rotating shaft and the stirring blade to rotate. When the stirring blade rotates, the stirring blade can drive the water to rotate. The rotation of the water can prevent the dust in the water from settling at the bottom of the purification shell, further reducing the subsequent cleaning work of the purification shell.

[0011] According to the exhaust gas emission detection device, a first pipeline is arranged at the top of the purification shell, a strip-shaped through groove is opened at the bottom of the purification shell, and a second pipeline is arranged at the bottom of the strip-shaped through groove.

[0012] By arranging a first pipe on the top of the purification shell, water can enter the purification shell through the first pipe; by opening a strip groove at the bottom of the purification shell, water in the purification shell can enter the second pipe through the strip groove and be discharged from the second pipe.

[0014] A plurality of silencer holes are provided on the silencer plate. When the exhaust gas enters the silencer shell, the exhaust gas passes through the silencer holes. During this process, the silencer plate can slow down the flow rate of the exhaust gas, thereby reducing the noise generated when the exhaust gas is discharged.

[0015] According to the exhaust gas emission detection device, a hoop is provided at the connection between the filter shell and the connecting pipe, the inner side of the hoop has a slot, and the outer wall of the filter shell and the adjacent end of the connecting pipe has a limiting portion located in the slot.

[0016] The hoop is divided into two parts, an upper part and an lower part, which are connected by bolts. By setting the hoop, when the filter shell and the connecting pipe are connected, the upper and lower parts of the hoop are sleeved on corresponding positions, so that the limiting parts of the filter shell and the connecting pipe are located in the slots, and the bolts are tightened, so that the filter shell and the connecting pipe can be fixed by the hoop. When the filter shell and the connecting pipe are disconnected, the bolts can be loosened, so that the upper and lower parts of the hoop can be separated, and the connection between the filter shell and the connecting pipe can be further disconnected.

[0017] According to the exhaust gas emission detection device, the filter assembly also includes a connecting rod, a fixed plate and a filter screen, and fixed plates are provided at both ends of the connecting rod. The filter screen is sleeved on the connecting rod and located between the two fixed plates, wherein one fixed plate and the filter screen are both located in the filter shell, and the other fixed plate is located in the connecting pipe.

[0018] When installing the connecting rod, the fixing plate and the filter screen, the fixing plate and the filter screen are fixedly mounted on the connecting rod. By setting the fixing plate and the connecting rod, the filter screen can be fixed in the filter shell; when cleaning the filter screen, the connection between the filter shell and the connecting pipe is disconnected, and the filter screen and other components can be taken out of the filter shell.

[0019] According to the exhaust gas emission detection device, a retaining ring is arranged in the connecting pipe, and another fixing plate is located on one side of the retaining ring.

[0020] When the filter housing is connected to the connecting pipe, the two fixing plates are clamped at the connection between the retaining ring and the filter housing and the air outlet pipe; by providing the retaining ring, the fixing plates can be prevented from moving with the air flow.
