Description

Technical Field

[0001] The present application relates to the technical field of waste gas treatment equipment, and more specifically, to a chemical waste gas purification and recovery equipment. Background Art

[0002] The organic gas in paint waste gas comes from the volatilization of solvents and diluents. Organic solvents will not adhere to the surface of the paint with the paint, and will be completely released to form organic waste gas during the painting and curing process. The amount of xylene waste gas volatilized in the painting process accounts for about 30% of the diluent usage, and another 70% volatilizes during the drying process. The existing waste gas purification equipment cannot replace the filter plate, has poor treatment effect, low efficiency, and substandard emissions, and cannot meet the use requirements of different working conditions.

[0003] The document with prior art publication number CN 214287335 U provides an integrated paint chemical waste gas recovery and purification treatment device, which separates particulate matter in the waste gas through a cyclone separator. After separation, the particulate matter falls from the inner wall of the cyclone separator into a dust collection box for treatment, thereby improving the filtration efficiency and making the emission meet the standards.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: when the device processes the particulate matter in the dust box, since the device lacks a closing valve, the equipment needs to be shut down when the dust box is taken out to prevent the particulate matter from falling. The traditional method is to install a valve through the lower end of the cyclone separator, and the opening and closing of the dust exhaust pipe can be controlled by the valve. However, there is also the problem that the workers do not operate in a standardized manner and forget to close the valve, which will cause a large amount of particulate matter to overflow when the equipment is operating normally. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] The purpose of the present application is to provide a chemical waste gas purification and recovery equipment, which solves the technical problems in the above-mentioned background technology and realizes the removal of the dust collecting tube during the normal operation of the equipment. When the dust collecting tube is taken out, the lower end of the dust exhaust pipe is closed at the same time, ensuring that the equipment does not stop to clean the particulate matter in the dust collecting tube, and at the same time avoids the technical effect of forgetting to close the valve and causing the particulate matter to overflow.

[0007] 2. Technical solution

[0008] The technical solution of the present application provides a chemical waste gas purification and recovery device, including a cyclone separator, the cyclone separator includes a dust exhaust pipe, the bottom of the dust exhaust pipe is connected to a drawer box with a through hole, a drawer with a closed upper end and a handle is slidably arranged in the drawer box, an installation opening corresponding to the through hole is opened on the upper surface of the drawer, a dust collecting barrel is installed in the installation opening, the distance between the side of the dust collecting barrel away from the handle and the installation opening is greater than the diameter of the through hole, and the drawer and the drawer box are detachable.

[0009] By adopting the above technical scheme, during the process of separating particulate matter and gas by the cyclone separator, the particulate matter passes through the dust exhaust pipe and then falls into the dust collecting bin through the through hole. When the particulate matter in the dust collecting bin needs to be recovered and cleaned, the drawer and the drawer box are disassembled, and the handle is pulled outward so that the dust collecting bin is placed outside the drawer box. At the same time, the through hole is blocked by the upper surface of the drawer. At this time, the dust collecting bin is taken out from the installation port and the particles are poured out. The dust collecting bin is then installed into the installation port and pushed into the drawer box, so that the dust collecting bin is placed directly under the through hole so that the particulate matter can be collected again.

[0010] As an optional solution of the technical solution of the present application document, the side wall of the drawer is rotatably connected with a strip board, a T-shaped shaft is fixedly installed on one side of the drawer box close to the strip board, and a bayonet is opened at one end of the strip board close to the T-shaped shaft.

[0011] By adopting the above technical solution, the strip plate axis is rotatably connected to the side wall of the drawer, and the strip plate is rotated so that the bayonet is clamped on the T-axis, thereby fixing the drawer and the drawer box. When the strip plate is rotated counterclockwise, the strip plate is disengaged from the T-axis, and the drawer and the drawer box can be separated.

[0012] As an optional solution of the technical solution of the present application document, the drawer box is symmetrically provided with strip holes, and the drawer is symmetrically fixed with sliders that slide along the strip holes.

[0013] By adopting the above technical solution, when the slider abuts against the right side of the strip hole, the upper surface of the drawer can completely block the through hole to facilitate rapid positioning and prevent the drawer from being pulled out of the drawer box.

[0014] As an optional solution of the technical solution of the present application document, the upper end opening of the dust collecting cylinder is symmetrically provided with notches.

[0015] By adopting the technical solution, the dust collecting cylinder can be taken out from the installation opening through the notch.

[0016] As an optional solution of the technical solution of the present application document, the drawer is placed below the installation opening and an electronic scale is fixedly installed thereon, and the electronic scale includes a display screen fixed to the outer wall of the drawer.

[0017] By adopting the above technical solution, when the dust bin is placed in the installation port and placed on the electronic scale, the weight of the dust bin is displayed and recorded on the display screen. The weight is displayed digitally on the display screen. When the digital display reaches the set value, the worker can clean the particles in the dust bin in time without frequently pulling out the drawer for observation.

[0018] 3. Beneficial effects

[0019] One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0020] 1. In the process of separating particles and gas by the cyclone separator, the particles fall into the dust collecting bin through the dust exhaust pipe and the through hole. When the particles in the dust collecting bin need to be recovered and cleaned, the drawer and the drawer box are disassembled, and the handle is pulled outward so that the dust collecting bin is placed outside the drawer box. At the same time, the through hole is blocked by the upper surface of the drawer. At this time, the dust collecting bin is taken out from the installation opening and the particles are poured out. Then, the dust collecting bin is installed into the installation opening and pushed into the drawer box, so that the dust collecting bin is placed just below the through hole and can collect particles again.
