Description

Technical Field

[0001] The utility model relates to the technical field of biomass purification, and particularly relates to a purification system for biomass combustion. Background Art

[0002] During the combustion process of a combustion furnace, a large amount of harmful gases will be generated, which will affect the surrounding staff and environment during exhaust. Therefore, it is necessary to purify them.

[0003] The existing purification method mainly filters these harmful gases through an activated carbon filter screen, so as to absorb the harmful gases, and then discharge the purified gas after purification. However, after long-term filtration, the activated carbon filter screen will be gradually polluted and blocked by harmful gases, and finally it will be unable to purify the harmful gases. In order to address the above problems and defects, a purification system for biomass combustion is urgently needed. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a purification system for biomass combustion to solve the problem that the existing purification method mainly filters these harmful gases through an activated carbon filter screen, so as to absorb the harmful gases, and then discharge the purified gas after purification. However, after long-term filtration, the activated carbon filter screen will be gradually polluted and blocked by harmful gases, and finally it will be unable to purify the harmful gases.

[0005] To solve the above technical problem, the utility model provides the following technical solutions:

[0006] A purification system for biomass combustion, comprising: a combustion furnace, a connecting pipe fixedly communicated with the top of the combustion furnace, a fan fixedly assembled on the inner wall of the connecting pipe, a square groove opened on the inner wall of the connecting pipe, a circular groove opened on the inner wall of the square groove, a spring fixedly assembled on the inner wall of the circular groove, a connecting block fixedly assembled at the bottom of the spring, a clamping block fixedly assembled at the bottom of the connecting block, a fixing pin clamped on the outer wall of the clamping block, a filter screen fixedly assembled on the side of the fixing pin away from the square groove, a through groove opened on the outer wall of the connecting pipe, and a pull ring fixedly assembled on the outer wall of the connecting block and passing through the through groove.

[0007] A groove is opened on the top of the combustion furnace, and a hanging ring is rotatably connected to the inner wall of the groove.

[0008] A sealing gasket is fixedly assembled on the outer wall of the filter screen, and the side of the sealing gasket away from the filter screen abuts against the connecting pipe.

[0009] A positioning groove is opened on the side of the connecting pipe close to the combustion furnace, and a one-way valve is fixedly assembled on the inner wall of the positioning groove.

[0010] On the side of the filter net away from the connecting pipe, a fixing groove is provided, and a handle is fixedly assembled on the inner wall of the fixing groove.

[0011] The cross-sectional shape of the clamping block is a right trapezoid, and the hypotenuse of the clamping block is on the side close to the fixing pin.

[0012] Compared with the prior art, the present utility model has at least the following beneficial effects:

[0013] 1. In the above solution, when biomass burns in the combustion furnace, the blower provides suction to suck the harmful gases generated in the combustion furnace upward. When the harmful gases pass through the filter net, the filter net purifies these harmful gases, and the purified gas is discharged from the combustion furnace. After the operation is completed, by pulling the pull ring, the pull ring and the clamping block are moved upward, so that the clamping block is separated from the filter net, and the filter net can be removed and a new filter net can be replaced. Then, the new filter net is inserted into the connecting pipe. When the fixing pin on the filter net is inserted into the square groove, the clamping block is squeezed and moves deeper into the circular groove. When the fixing pin is completely inserted into the square groove, the clamping block loses the extrusion, and the connecting block and the clamping block are inserted toward the fixing pin by the spring until they are clamped with the fixing pin, thus completing the replacement of the filter net, which is beneficial to ensuring the filtering effect on harmful gases and is also convenient for maintaining the filter net.

[0014] 2. In the above solution, by providing the groove and the hanging ring, it is beneficial to move the device in position through the hanging ring, which is beneficial to improving the convenience of the device. BRIEF DESCRIPTION OF THE DRAWINGS
