Chlorine dioxide generator

Abstract

The invention discloses a chlorine dioxide generator. The chlorine dioxide generator comprises a casing, a communicating pipe, a reaction kettle and an explosion-proof device, wherein the reaction kettle and the explosion-proof device are arranged in the casing; the explosion-proof device comprises an explosion-proof buffer tank located in the casing; the communicating pipe is communicated with the explosion-proof buffer tank and atmosphere, is used for exhausting gas in the explosion-proof buffer tank and is further used for inputting gas into the reaction kettle through the explosion-proof buffer tank for aeration; the reaction kettle is communicated with the explosion-proof buffer tank through a gas inlet pipe and an exhaust pipe, the gas inlet pipe is used for extending below the liquid level in the reaction kettle, and the exhaust pipe is communicated with the upper part of the reaction kettle; an explosion-proof plug is arranged in the position, corresponding to the exhaust pipe, of the explosion-proof buffer tank. According to the chlorine dioxide generator, the reaction kettle is communicated with the explosion-proof buffer tank through the gas inlet pipe and the exhaust pipe, gas intake and exhaust are realized by the aid of the communicating pipe communicated with the atmosphere and arranged on the explosion-proof buffer tank, chlorine dioxide gas can be prevented from being accumulated in the communicating pipe, and safe operation of equipment is guaranteed.

Description

technical field [0001] The invention relates to the technical field of machinery industry, and more specifically, relates to a chlorine dioxide generator. Background technique [0002] The chlorine dioxide generator is used to produce chlorine dioxide. During application, two reagents, agent A and agent B, need to be added into the chlorine dioxide generator and react to generate chlorine dioxide. [0003] The chlorine dioxide generator includes a reactor, a water injector and an explosion-proof structure, wherein the reactor communicates with the outside atmosphere through an air inlet pipe. During application, the water ejector continuously pumps out the gas produced by the chemical reaction of agent A and agent B in the reaction kettle out of the reflection pot, and when the water ejector stops working due to water failure, etc., the gas in the reflection pot needs to pass through the pipeline It is transported to the explosion-proof structure for discharge. When the wat...

Problems solved by technology

[0004] Obviously, in the above-mentioned chlorine dioxide generator, when the pressure in the pipeline connecting the explosion-proof device and the atmosphere is the same as the atmospheric pressure after the water injector is deactivated, the gas cannot continue to be discharged, causing a large amount of chlorine dioxide gas to accumulate in the pipeline. Bad for device security
