Technical Field

[0001] The utility model belongs to the technical field of sludge drying equipment, and in particular relates to a waste gas collection and treatment device for sludge drying equipment. Background Art

[0002] Sludge drying equipment is a device used to reduce the moisture content of sludge. It reduces the volume of sludge through physical methods to facilitate transportation, stacking, utilization or further processing. The advanced technology applied in sludge drying equipment, namely the combination of solar energy and heat pump technology, sludge is dried at low temperature. Sludge drying equipment is widely used in municipal sludge, printing and dyeing sludge, papermaking sludge, electroplating sludge and other fields. The existing sludge drying equipment is mostly sludge dryers, and when the sludge drying equipment is in operation, a lot of waste gas will be generated. Users will need to use waste gas collection and treatment devices to collect and treat the generated waste gas.

[0003] When the waste gas passes through the sludge drying equipment and the pipeline into the waste gas collection and treatment device, the transmission speed of the waste gas in the pipeline is certain, and there is no effective traction force outside the pipeline, so the transmission speed of the waste gas cannot be accelerated as needed, and the treatment speed of the waste gas cannot be accelerated. Even if there is traction on the device, it is installed after the purification end, and the traction effect on the waste gas is poor. Utility Model Content

[0004] In response to the problems existing in the existing technology, the utility model provides a waste gas collection and treatment device for sludge drying equipment, which solves the problem that there is no effective traction force outside the pipeline, thereby failing to accelerate the transmission speed of the waste gas as needed, resulting in the inability to speed up the treatment of the waste gas.

[0005] The exhaust gas fan of the gas purification device is connected with the exhaust gas fan of the gas pump, and the exhaust gas fan of the gas injector is connected with the exhaust gas injector of the gas injector.

[0006] As a preferred embodiment of the present invention, the length and width of the blocking plate are both greater than the diameter of the exhaust duct, and a positioning frame is fixed to the bottom of the right side of the blocking plate.

[0007] As a preferred embodiment of the present invention, a plurality of groups of Venturi tubes are sequentially connected along the front-to-back direction of the impact tube, and the plurality of groups of Venturi tubes are all located above the exhaust pipe.

[0008] As a preferred embodiment of the present invention, one end of the exhaust pipe close to the impact pipe is in a downwardly inclined structure, and a section where the impact pipe and the exhaust pipe are connected to each other is in a vertical structure.

[0009] As a preferred embodiment of the present invention, a support frame is fixed on the mounting ring, and the top of the support frame is attached to the bottom of the rotary cover.

[0010] As a preferred embodiment of the present invention, a bracket is fixed on the right side of the top of the round sleeve, an insertion rod is inserted on the left side of the top of the bracket, and the bottom end of the insertion rod is inserted on the installation tube.

[0011] As a preferred embodiment of the present invention, the number of the Venturi tubes is at least two groups.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0013] The utility model sets an air pump to quickly transport external air into the impact tube, and the air entering the impact tube at this time has a certain speed, and the speed here is greater than the transmission speed of the exhaust gas in the exhaust pipe. In conjunction with the limiting structure composed of a sealing plate and a positioning frame, the air in the impact tube can be quickly and directionally moved, and under the action of the flow rate, a certain negative pressure is formed at the joint between the impact tube and the exhaust pipe, so that the negative pressure can be used to form a certain traction force on the exhaust gas in the exhaust pipe, thereby facilitating the rapid pulling out of the exhaust gas in the exhaust pipe, accelerating the transmission speed of the exhaust gas, and enabling the exhaust gas to quickly enter the treatment tube for purification, thereby directly accelerating the treatment speed of the exhaust gas.

[0020] In order to further understand the content, features and effects of the present invention, the following embodiments are listed and described in detail with reference to the accompanying drawings.

[0021] The structure of the present utility model is described in detail below with reference to the accompanying drawings.

[0022] like Figures 1 to 4 As shown, an embodiment of the present invention provides a waste gas collection and treatment device for sludge drying equipment, comprising an exhaust pipe 1 capable of docking with a waste discharge pipe of a sludge dryer, and further comprising: a treatment cylinder 2 located on one side of the exhaust pipe 1, a controller being provided at the bottom of one side of the treatment cylinder 2, a screw cap 3 being engaged with the treatment cylinder 2 through an internal thread, an air pump 5 being fixed to the bottom of one side of the treatment cylinder 2 through a mounting sleeve, an air outlet end of the air pump 5 being connected to an impact pipe 6 and one end of the exhaust pipe 1 being connected to the impact pipe 6, an end of the impact pipe 6 away from the air pump 5 being connected to the treatment cylinder 2, an end of the exhaust pipe 1 close to the impact pipe 6 being connected to a square box 4, and a sealing plate 16 for sealing the impact pipe 6 being rotatably mounted on the top of one side of the inner cavity of the square box 4. A filter cartridge 10 is placed at the bottom of the inner cavity of the treatment cartridge 2, and a mounting ring 11 is fixed to the top of the surface of the filter cartridge 10. The outer surface of the mounting ring 11 is fitted to the inner wall of the treatment cartridge 2 through a rubber ring. The bottom of the other side of the treatment cartridge 2 is connected to a mounting cartridge 8, and a circular sleeve 12 is clamped in the mounting cartridge 8. An activated carbon filter screen 13 is fixed in the circular sleeve 12. By setting an air pump 5 and cooperating with a limiting structure composed of a sealing plate 16 and a positioning frame 17, the air in the impact pipe 6 can be directed at a certain speed, and under the action of a faster flow rate, a negative pressure state is formed at the junction of the impact pipe 6 and the exhaust pipe 1, so that the exhaust gas in the exhaust pipe 1 can be quickly pulled out by using the negative pressure, thereby accelerating the transmission speed of the exhaust gas.

[0023] Preferably, the length and width of the blocking plate 16 are both greater than the diameter of the exhaust pipe 1. A positioning frame 17 is fixed to the bottom of the right side of the blocking plate 16. The different diameters are designed so that the blocking plate 16 can completely block the exhaust pipe 1. The design of the positioning frame 17 can limit the blocking plate 16 to prevent the blocking plate 16 from completely flipping to the top of the inner cavity of the square box 4, affecting its reset and blocking effect under reverse gas impact.

[0024] Preferably, multiple groups of Venturi tubes 7 are connected in sequence along the front-to-back direction on the impact tube 6, and the multiple groups of Venturi tubes 7 are all located above the exhaust pipe 1. The design of the Venturi tubes 7 can accelerate the gas in the impact tube 6 so as to stably form a negative pressure state at the interface.

[0025] As a preferred embodiment of the present invention, one end of the exhaust pipe 1 close to the impact pipe 6 is in a downward inclined structure, and the section where the impact pipe 6 and the exhaust pipe 1 are connected to each other is in a vertical structure, so that the gas in the impact pipe 6 can move in a direction, avoiding reverse impact into the exhaust pipe 1, which affects the normal flow of exhaust gas.

[0026] Preferably, a support frame 9 is fixed on the mounting ring 11, and the top of the support frame 9 is attached to the bottom of the rotary cover 3. The design of the support frame 9, in conjunction with the rotary cover 3, can stably position the filter cartridge 10 and facilitate the subsequent removal of the filter cartridge 10 from the treatment cartridge 2 for cleaning or replacement.

[0027] Preferably, a bracket 14 is fixed to the right side of the top of the circular sleeve 12, and an insertion rod 15 is inserted on the left side of the top of the bracket 14, and the bottom end of the insertion rod 15 is inserted on the mounting tube 8. The design of the bracket 14 and the insertion rod 15 can quickly assemble the activated carbon filter 13, and is also convenient for subsequent disassembly, so as to facilitate the cleaning, maintenance or replacement of the activated carbon filter 13.

[0028] Preferably, the number of the venturi tubes 7 is at least two groups. By increasing or decreasing the number of the venturi tubes 7 , the gas flow rate in the impact tube 6 can be freely adjusted.

[0029] The working principle of this utility model:

[0030] refer to Figures 1 to 4 The exhaust gas in the sludge dryer has a certain speed when it is discharged through the exhaust pipe 1. If the exhaust gas needs to be accelerated, the user turns on the air pump 5 through the controller. The air pump 5 can transport the external gas to the impact pipe 6, and the gas has a certain speed. Then, under the alternating acceleration of multiple sets of venturi tubes 7, the gas can move in the impact pipe 6 at a faster speed. Moreover, since one end of the exhaust pipe 1 is inclined and cooperates with the restriction structure similar to a one-way valve composed of the sealing plate 16 and the positioning frame 17, the air in the impact pipe 6 can be quickly discharged. The exhaust pipe 1 is provided with a plurality of filter elements, and the filter element 1 has ...
