Description

A safety emission device for waste gas from chemical production equipment Technical Field

[0001] This utility model belongs to the field of waste gas treatment technology, and more specifically, it relates to a safe emission device for waste gas from chemical production equipment. Background Technology

[0002] Chemical waste gas refers to toxic and harmful gases discharged from chemical plants during chemical production, which seriously pollute the environment and affect human health. The composition of chemical waste gas varies greatly among different chemical production industries. In modern chemical production, these waste gases are treated accordingly to reduce pollution and damage to the external environment.

[0003] When applying for this utility model, the applicant, after searching, discovered a Chinese patent disclosing "A Waste Gas Emission Device for a Chemical Production Workshop," application number "CN201921922589.5." This patent mainly utilizes a treatment chamber, water storage base, water tank, first exhaust fan, first exhaust pipe, ventilation branch pipe, water inlet pipe, spray head, demister, connecting pipe, suction hood, second exhaust fan, ventilation pipe, second exhaust pipe, activated adsorption plate, water pipe, and integrated pipe in conjunction. In use, the first and second exhaust fans are activated. The waste gas enters the water tank, where some harmful elements dissolve in the water or form precipitates. Simultaneously, bubbles rise to the water level, burst, and pass through the demister, trapping acidic and alkaline impurities. The remaining gas enters the second outlet pipe for final adsorption, resulting in more thorough waste gas treatment. This invention is easy to use; the designed water tank, demister, and activated adsorption plate maximize waste gas adsorption and impurity removal, leading to more effective gas treatment and significantly enhanced performance. Furthermore, the device is inexpensive and suitable for widespread adoption.

[0004] However, this device uses the method of directly introducing gas into the water tank, allowing the gas to react naturally with the water in the tank. The reaction speed is slow, and there will be situations where the gas is sucked out of the treatment chamber before it has fully reacted with the water, resulting in low waste gas treatment efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a safe emission device for waste gas from chemical production equipment, which features high waste gas treatment efficiency and complete reaction.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A safety emission device for waste gas from chemical production equipment is provided, comprising a reaction tank. A top cover is bolted to the top of the reaction tank. Two protective shells are bolted to the top of the top cover. Motors are mounted on the outer walls of both protective shells. A drive shaft is bolted to the output end of each motor. Multiple blades are bolted to the outer wall of the drive shaft. A drive wheel is bolted to one end of the drive shaft on the left side through the protective shell. A support plate is bolted to the top of the top cover. The outer wall of the support plate... The unit is equipped with a driven wheel, and a driving bevel gear is fixedly connected to the outer wall of the driven wheel. The driving wheel is connected to the driven wheel through a synchronous toothed belt. A driven bevel gear is provided on the top of the top cover, and a driven shaft is fixedly connected to the bottom of the driven bevel gear. A helical reciprocating groove is formed on the outer wall of the driven shaft. A reciprocating ring is fitted on the outer wall of the driven shaft. A protrusion is fixedly connected to the inner wall of the reciprocating ring. The protrusion is located inside the helical reciprocating groove. A limiting block is fixedly connected to the outer wall of the reciprocating ring. A limiting groove is formed on the inner wall of the reaction vessel, and there are multiple limiting grooves. The limiting block is located inside the limiting groove.

[0007] Optionally, the driven wheel and the driving bevel gear are located on both sides of the support plate, and the outer wall of the driving bevel gear meshes with the outer wall of the driven bevel gear.

[0008] Optionally, an air inlet duct is fixedly connected to the bottom of the left protective shell, and an air inlet is fixedly connected to the top of the left protective shell. The air inlet duct extends through the top cover into the interior of the reaction vessel. An exhaust duct is fixedly connected to the bottom of the right protective shell, and an exhaust port is fixedly connected to the top of the right protective shell.

[0009] Optionally, a filter tube is threadedly connected to the inner wall of the air inlet, and a filter screen is fixedly connected inside the filter tube.

[0010] Optionally, a fixing plate is fixedly connected to the top of the reaction vessel, and the drive shaft on the left side passes through the interior of the fixing plate.

[0011] Optionally, the top of the reaction vessel is fixedly connected with two lifting lugs, and a sealing gasket is provided between the top of the reaction vessel and the top cover.

[0012] Optionally, an inlet pipe is fixedly connected to the outer wall of the reaction vessel, and an inlet valve is fixedly connected to the top of the inlet pipe.

[0013] Optionally, the bottom of the reaction vessel is fixedly connected to a support leg, and there are multiple support legs, with a base plate fixedly connected to the bottom of the multiple support legs.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention introduces water into the reaction vessel through an inlet pipe. Two motors then operate, driving multiple blades on the left and right sides respectively. The left motor draws gas into the reaction vessel through the inlet and inlet duct, where it reacts with the water. The right motor draws the reacted gas out of the reaction vessel. The left motor drives the drive shaft and drive wheel to rotate. The drive wheel is connected to the driven wheel via a synchronous toothed belt, causing the driven wheel and drive bevel gear to rotate synchronously. Simultaneously, the drive bevel gear meshes with the driven bevel gear, causing the driven bevel gear and driven shaft to rotate. A spiral reciprocating groove is formed on the outer wall of the driven shaft, and the protrusions on the inner wall of the reciprocating ring are located inside the spiral reciprocating groove. At the same time, multiple limiting blocks are set on the outer wall of the reciprocating ring. Under the action of the limiting groove on the inner wall of the reaction tank, the reciprocating ring moves up and down along the driven shaft when the driven shaft rotates. In addition, multiple inclined connecting plates are set inside the reciprocating ring. When the reciprocating ring moves up and down, water can pass through the gaps between the connecting plates, which accelerates the flow rate of the water and agitates the water. Agitation can break the stagnant layer at the gas-liquid interface, increase the contact area between the waste gas and the liquid, promote the dissolution of gas or the diffusion of reactants into the liquid, thereby accelerating the reaction and improving the waste gas treatment efficiency.
