Description

Technical Field

[0001] This utility model belongs to the field of glyphosate mother liquor directional conversion tail gas treatment technology, specifically relating to a tail gas pre-dust removal treatment device for glyphosate mother liquor directional conversion. Background Technology

[0002] Glyphosate mother liquor is characterized by high salt, high phosphorus, and high COD, and its complex composition makes it difficult to degrade. It is a typical high-concentration organophosphorus wastewater. Targeted thermal conversion treatment of glyphosate mother liquor is an effective way to reduce its volume, render it harmless, and recycle it. During targeted thermal conversion treatment, after the mother liquor and fuel gas are burned in the targeted conversion furnace, the flue gas produced by the furnace contains a large amount of dust, particles, and impurities. In order to meet environmental protection requirements, dust removal treatment of the flue gas produced by the targeted conversion furnace is an essential treatment step.

[0003] In existing technologies, dust collectors used for exhaust gas from directional converters mainly consist of bag filters and electrostatic precipitators. The dust removal performance of electrostatic precipitators is significantly affected by the physical and chemical properties of the dust, and their effectiveness is not ideal for high resistivity dust, fine dust, and highly viscous dust. While bag filters are used directly for dust removal when there is a large amount of dust, this can easily affect the normal operation of the equipment, shorten its service life, and cause inconvenience in maintenance, thus affecting processing efficiency. Furthermore, directly using these two dust removal methods requires significant investment in subsequent maintenance, resulting in high costs and inconvenience in the subsequent absorption and treatment of exhaust gas, leading to delays in the testing of exhaust gas dust removal effectiveness.

[0004] Therefore, in order to solve the above problems, it is necessary to develop a tail gas pre-dust removal treatment device for the directional conversion of glyphosate mother liquor. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a pre-dust removal device for the tail gas of glyphosate mother liquor directional conversion. It is used to pre-treat the directional tail gas before the main dust collector, improve the efficiency of the dust collector, reduce impurities in the directional tail gas, facilitate subsequent dust removal and tail gas purification and absorption, and save dust removal costs and time.

[0006] The purpose of this utility model is achieved as follows: a pre-dust removal device for tail gas of glyphosate mother liquor directional conversion, including an inertial collision dust removal device and a tail gas detection device.

[0007] The inertial collision dust removal device includes a dust removal body, an air inlet pipe connected to one side of the bottom of the dust removal body, a filter screen installed in the air inlet pipe near the dust removal body, an impurity discharge pipe connected to the bottom of the air inlet pipe, the air inlet pipe and the impurity discharge pipe being arranged in a T-shape, and an exhaust pipe connected to the top of the dust removal body.

[0008] The dust removal body has multiple dust baffles fixedly installed inside. The dust baffles are arranged in an inverted L-shaped structure and are installed in a staggered, stepped manner.

[0009] The bottom of the dust removal body is arranged in a funnel shape and a dust discharge port is provided at the bottom end. Vibrators are provided on the outer walls on both sides of the dust discharge port at the bottom of the dust removal body.

[0010] The exhaust gas detection device includes an intake gas detection device and an exhaust gas detection device respectively installed on the intake pipe and the exhaust pipe.

[0011] Furthermore, control valves are respectively installed on the impurity discharge pipe and at the dust discharge outlet.

[0012] Furthermore, the filter screen is made of stainless steel and the pore size is 2-5mm.

[0013] Furthermore, the dust baffle is provided in three pieces, which are welded to the inner wall of the dust removal body by fixing brackets and are installed in a stepped staggered manner with a certain distance between them.

[0014] Furthermore, the oscillator is a variable frequency oscillator, and two oscillators are configured, which are respectively located on both sides of the dust discharge outlet.

[0015] Furthermore, both the intake gas detection device and the exhaust gas detection device include an online particulate matter analyzer, an online temperature and humidity analyzer, and a gas composition detection device, which respectively measure the directional gas in the intake pipe before dust removal and the exhaust pipe after dust removal, and transmit the measurement data remotely.

[0016] The beneficial effects of this utility model are as follows: By incorporating a dust baffle plate inside the dust collector body for inertial collision, this utility model achieves dust removal through physical inertial collision. The dust removal process is less affected by charged ion dust, resulting in good gas pretreatment and dust removal effects. Furthermore, by arranging the bottom of the dust collector body in a funnel shape with a dust discharge outlet and installing variable frequency oscillators on both sides, the vibration frequency can be adjusted on-site and remotely. The operating time and vibration frequency of the variable frequency oscillators can be preset for timed operation, preventing excessive dust accumulation inside the inertial collision dust collector. Cleaning is difficult, and dust accumulation outlets are easily blocked. The system boasts a high degree of automation and effective dust removal. By incorporating an exhaust gas detection device, the system measures the directional gas in the inlet pipe before dust removal and the exhaust pipe after dust removal, transmitting the data remotely. This allows for the detection and comparison of the pre-treated exhaust gas, providing data for further thorough dust removal and exhaust gas treatment. The data collection is comprehensive, and the gas information is complete, facilitating subsequent processing. In summary, this invention offers advantages such as easier subsequent processing, improved dust collector efficiency, and savings in dust removal costs and time. Attached Figure Description

[0023] like Figure 1 As shown, a pre-dust removal device for glyphosate mother liquor directional conversion includes an inertial collision dust removal device 1 and a tail gas detection device 2.

[0024] The inertial collision dust removal device 1 is used to process large particles, dust, and impurities, reducing the particle size and dust content of the directional exhaust gas. The inertial collision dust removal device 1 includes a dust removal body 11, which is generally cylindrical. An air inlet pipe 12 is connected to one side of the bottom of the dust removal body 11. A filter screen 13 is installed inside the air inlet pipe 12 near the dust removal body 11. An impurity discharge pipe 14 is connected to the bottom end of the air inlet pipe 12, and a control valve is installed on the impurity discharge pipe 14. The air inlet pipe 12 and the impurity discharge pipe 14 are arranged in a T-shape. An exhaust pipe 15 is connected to the top of the dust removal body 11. Preferably, the filter screen 13 is made of stainless steel and has a pore size of 2-5 mm. The exhaust gas enters the air inlet pipe 12, is filtered by the filter screen 13, and then enters the dust removal body 11. Larger impurities are filtered out by the filter screen 13, and the impurities enter the impurity discharge pipe 14 for collection and treatment.

[0025] The dust removal body 11 is internally equipped with multiple dust baffles 16, which are arranged in an inverted L-shape and are installed in a stepped staggered manner. Preferably, there are three dust baffles 16, which are welded to the inner wall of the dust removal body 11 by fixing brackets and are installed in a stepped staggered manner with a certain distance between them. Both the dust baffles 16 and the fixing brackets are made of stainless steel.

[0026] The dust removal body 11 has a funnel-shaped bottom with a dust discharge outlet 17 at the bottom. A control valve is installed at the dust discharge outlet 17. Vibrators 18 are installed on the outer walls of the bottom of the dust removal body 11 on both sides of the dust discharge outlet 17. Preferably, a sight glass is also provided at the bottom of the dust removal body 11 to facilitate observation of internal dust accumulation and dust removal. Preferably, the vibrators 18 are variable frequency vibrators, and two vibrators 18 are set and respectively installed on both sides of the dust discharge outlet 17. The vibration frequency can be adjusted on-site and remotely controlled. The working time and vibration frequency of the variable frequency vibrators can be preset for timed operation to prevent inertial collisions. The dust removal device has a lot of internal dust accumulation, which is difficult to clean and can clog the dust discharge outlet.

[0027] The exhaust gas detection device 2 includes an intake gas detection device 21 and an exhaust gas detection device 22 respectively installed on the intake pipe 12 and the exhaust pipe 15. Preferably, the intake gas detection device 21 and the exhaust gas detection device 22 each include an online particulate matter analyzer a, an online temperature and humidity analyzer b, and a gas composition analyzer c, which respectively measure the directional gas in the intake pipe 12 before dust removal and the exhaust pipe 15 after dust removal, and transmit the measurement data remotely to facilitate the staff to understand the gas composition, detect and compare the qualitative exhaust gas after pretreatment, and provide detection data for the next step of thorough dust removal and exhaust gas treatment.
