Description

Flue gas sampler with filter element capable of being replaced quickly

Technical Field

The utility model belongs to the technical field of the flue gas sampling, concretely relates to can quick replacement filter core flue gas sampling ware.

Background

The flue gas sampler is suitable for sampling flue gas of a continuous collection CEMS/VOCS analysis system of waste gas sample gas after a combustion process, and is widely applied to analysis systems with high water content, dust content and tar content in the power industry, the metallurgy industry and the cement kiln industry. In order to ensure the accuracy of the detected substances, the temperature of a sampling cavity in the smoke sampler is ensured to be not lower than 120 ℃ or even reach 180 ℃. The flue gas sample thief operating mode is mostly under high temperature, high wet, high dust, the high corrosive environment, because operating environment is more abominable, leads to the more frequent needs of flue gas sample thief inner filter core to wash, change, but the flue gas sample thief is often installed on high altitude flue, and the maintenance space is little and inconvenient carrying tool, and it is inconvenient to wash and change.

At present, flue gas samplers on the market mainly have two modes, one mode is that a bolt form is adopted to fix a filter element, the whole size of the flue gas sampler in the form is smaller, the whole installation of equipment is convenient, but the bolt is required to be disassembled by using tools when the filter element of the flue gas sampler is replaced, and because a chimney platform is smaller, the operation space is limited, time and labor are wasted, and screws at the installation part are easily damaged, so that the equipment cannot normally work. The other type adopts a rotary lock form to fix the filter element, the filter element is relatively convenient to replace, but the whole size of the flue gas sampler is large, and the equipment is extremely inconvenient to install. A smoke sampler with reduced overall size and quick filter element replacement is urgently needed.

Further, when the smoke sampler normally operates, the polytetrafluoroethylene gasket, the hoop flange 5 and the hoop flange cover 8 are tightly fixed together by the hoop 7 to realize the sealing of the device and the normal operation.

Further, the hoop 7 is provided with a hand bolt, so that the hoop 7 can be locked and unlocked.

Furthermore, one end of the joint piece 9 is communicated with the filter element 6, and the other end of the joint piece is used for being connected with a flue gas analysis system.

Compared with the prior art, the utility model beneficial effect does:

1. the mode of adopting the hoop replaces the bolt fastening or the rotatory lock fastening among the prior art, has reduced the operation requirement of changing the filter core and has dwindled the whole size of equipment.

2. Compared with the prior art, the mode of adopting the hoop has better stability of parts and greatly reduces the reject ratio of equipment installation.

3. The mode of fixing the filter element on the hoop flange cover is adopted, compared with the prior art, the mode of installing the filter element on the cavity is safer, and accidents can be effectively prevented.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

As shown in fig. 1-3, the flue gas sampler structure capable of rapidly replacing the filter element comprises a sampling pipe 1, a cavity flange 2, a heating ring 3, a cavity 4, a hoop flange 5, a filter element 6, a hoop 7, a hoop flange cover 8, a connector 9, a sampler shell 10 and a hasp lock 11. The sampling pipe 1 is positioned outside the sampler shell 10 and used for collecting gas, and the cavity flange 2, the heating ring 3, the cavity 4, the hoop flange 5, the filter element 6, the hoop 7, the hoop flange cover 8 and the joint piece 9 are positioned inside the shell, wherein the cavity flange 2, the cavity 4 and the hoop flange 5 are sequentially welded together, the cavity flange 2 is fixed on one surface of the sampler shell 10, the surface is provided with a through hole, and the sampling pipe 1 penetrates through the through hole and is fixed on the cavity flange 2 in a threaded manner and communicated with the cavity 4; the heating ring 3 is fixed on the cavity 4, the filter element 6 is arranged on the hoop flange cover 8 through threads, and the filter element 6 is inserted into the cavity 4 during sampling; a joint piece 9 is welded on the hoop flange cover 8, and the central hole of the joint piece 9 is communicated with the interior of the filter element 6; the other end is used for being connected with a flue gas analysis system, and the hoop 7 is used for fixing the hoop flange 5 and the hoop flange cover 8.
