Description

Technical Field

[0001] This utility model relates to the field of waste gas collection technology, and in particular to a waste gas collection and storage device for waste gas detection. Background Technology

[0002] Waste gas refers to toxic and harmful gases emitted during human production and daily life. Chemical plants, steel mills, pharmaceutical factories, coking plants, and oil refineries, in particular, emit waste gases with strong odors that severely pollute the environment and affect human health. Industrial production often generates waste gases, and to prevent these gases from harming human health, they are generally collected and tested for subsequent treatment.

[0003] Existing exhaust gas detection, collection, and storage devices collect exhaust gas through a gas pipe into a gas storage cylinder. Over time, the filter plate inside the gas pipe accumulates a lot of impurities. The filter plate is usually difficult to disassemble and assemble, and it is not convenient to replace it after the exhaust gas is collected, which can easily lead to leakage. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a waste gas collection and storage device for waste gas detection, thereby solving the problems mentioned in the background section.

[0005] An exhaust gas collection and storage device for exhaust gas detection includes an exhaust component. The input end of the exhaust component is connected to a first pipe, and the output end is connected to a second pipe. It also includes a collection mechanism connected to the second pipe via a first flexible hose. The collection mechanism includes a mounting plate, an exhaust chamber, a protrusion, a filter assembly, a connector, a connecting end, a second flexible hose, and an exhaust negative pressure bottle. The mounting plate is detachably installed at the upper end of the exhaust chamber. The protrusion is integrally installed at the bottom end of the exhaust chamber. The filter assembly is movably installed inside the protrusion. The connector is installed at the bottom of the protrusion. The connecting end is detachably installed on the connector. The exhaust negative pressure bottle is connected to the connecting end via the second flexible hose.

[0006] By adopting the above technical solution, it is convenient to collect exhaust gas and replace filter components and negative pressure gas collection bottles.

[0007] The filter assembly consists of a ring plate and filter cotton. The filter cotton is installed in the middle of the ring plate, and the ring plate also has a slot.

[0008] The above technical solution facilitates the placement and replacement of filter components.

[0009] The inner diameter of the protrusion is adapted to the outer diameter of the filter assembly.

[0010] By adopting the above technical solution, the exhaust gas passes through the filter from the middle of the filter component during the collection process.

[0011] Both hose one and hose two are silicone tubes.

[0012] By adopting the above technical solution, it is easier to control the opening of the gas collecting negative pressure bottle.

[0013] The center point of the protrusion, the center point of the filter assembly, and the center point of the connection end are all located on the same vertical line.

[0014] By adopting the above technical solution

[0015] The beneficial effects of this utility model's waste gas collection and storage device for waste gas detection are:

[0016] Place the gas collection negative pressure bottle directly below the gas collection chamber. Clamp the second hose using external clamps or similar items. Then, use an external air pump to draw gas from the gas collection negative pressure bottle, creating a negative pressure inside. Rotate the connecting end to connect the connector. After placing the gas collection negative pressure bottle, drive the exhaust component to collect exhaust gas through pipe one. The exhaust gas enters the gas collection chamber through pipe two and hose one. Open the clamps or similar items at hose two. The gas collection negative pressure bottle can then draw in the exhaust gas from the gas collection chamber. When the exhaust gas passes through the filter assembly, the filter assembly can filter out larger impurities in the exhaust gas. After the gas collection negative pressure bottle has finished collecting the gas, clamp the second hose again using external clamps or similar items. Rotate the connecting end to remove the gas collection negative pressure bottle, ready for subsequent testing. This facilitates exhaust gas collection, replacement of filter assemblies and gas collection negative pressure bottles, and prevents exhaust gas leaks. Attached Figure Description

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of the present invention.

[0022] Reference Figure 1-3 A waste gas collection and storage device for waste gas detection includes an exhaust component 1, with an input end connected to a pipe 2 and an output end connected to a pipe 3. It also includes a collection mechanism connected to the pipe 3 via a hose 4. The collection mechanism includes a mounting plate 5, a gas collection chamber 6, a protrusion 7, a filter assembly 8, a connector 9, a connecting end 10, a hose 11, and a negative pressure gas collection bottle 12. The mounting plate 5 is detachably installed at the upper end of the gas collection chamber 6. The protrusion 7 is integrally installed at the bottom end of the gas collection chamber 6. The filter assembly 8 is movably installed inside the protrusion 7. The connector 9 is installed at the bottom of the protrusion 7. The connecting end 10 is detachably installed on the connector 9. The negative pressure gas collection bottle 12 is connected to the connecting end 10 via the hose 11.

[0023] The filter assembly 8 consists of a ring plate and filter cotton. The filter cotton is installed in the middle of the ring plate, and the ring plate is also provided with a slot 801, which makes it convenient for the staff to place the filter assembly 8 into the protrusion 7. After a period of use, the filter assembly 8 can be removed from the protrusion 7 by holding the slot 801 for cleaning and replacement.

[0024] The inner diameter of the protrusion 7 is adapted to the outer diameter of the filter assembly 8 to ensure that the protrusion 7 is stably placed in the protrusion 7.

[0025] The center point of the protrusion 7, the center point of the filter assembly 8, and the center point of the connection end 10 are set on the same vertical line to ensure that when the exhaust gas is collected, it can pass smoothly through the gas collection chamber 6, the protrusion 7, and the connection end 10, and enter the gas collection negative pressure bottle 12 for collection.

[0026] Both hose 4 and hose 11 are silicone tubes. The gas collecting negative pressure bottle 12 is placed directly below the gas collecting chamber 6. Hose 11 is clamped using external clamps or similar items. An external air pump then draws gas from the gas collecting negative pressure bottle 12, creating a negative pressure inside.

[0027] After connecting the connecting end 10 to the connecting head 9 and placing the gas collection negative pressure bottle 12, the exhaust component 1 can be driven to collect exhaust gas through pipe 2. The exhaust gas enters the gas collection chamber 6 through pipe 3 and hose 4. Open the clamps or other items at hose 11, and the gas collection negative pressure bottle 12 can then draw in the exhaust gas from the gas collection chamber 6. When the exhaust gas passes through the filter component 8, the filter component 8 can filter out larger impurities in the exhaust gas. After the gas collection negative pressure bottle 12 has completed gas collection, the hose 11 can be clamped again with external clamps or other items. Then, rotate the connecting end 10 to remove the gas collection negative pressure bottle 12 and wait for subsequent testing.

[0028] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
