Problems solved by technology

In the production of sodium chlorate solution, it is inevitable that some organic substances such as epoxy resin in pipe materials and inorganic substances such as sulfate radicals will be brought into the generator. The existence of these impurities changes the surface tension of the solution in the generator. A large amount of foam is produced, and a large amount of chlorine dioxide gas is wrapped in the foam. If the chlorine dioxide gas cannot be released and absorbed quickly, it will decompose. However, the chemical properties of chlorine dioxide gas are extremely unstable, and it is very easy to decompose and generate chlorine gas. It will release a large amount of energy with oxygen, and its volume will expand to 1.5 times its original size during the decomposition process, which will cause great harm to production equipment and facilities.
In addition, frequent decomposition will greatly reduce production efficiency and increase manufacturing costs

Embodiment 2

[0024] see figure 2 , the difference between this embodiment and embodiment 1 is that the control device 5 includes a controller 7 and a liquid level gauge 9, the controller 7 is connected with the liquid level gauge 9 and the automatic regulating valve 6 respectively, and the liquid level gauge 9 is installed On the side wall of the reactor 3 at a certain height, when a certain amount of foam is generated in the reactor 3, the liquid level of the solution rises and touches the liquid level gauge 9, the liquid level gauge 9 transmits the signal to the controller 7, and the controller 7 and Control the opening of the automatic regulating valve 6, so that the tributyl phosphate solution immediately enters the inside of the generator 3 for defoaming. This setting makes the defoaming more automatic, which can effectively avoid excessive decomposition of chlorine dioxide inside the generator 3 in time, and avoid damage to equipment caused by excessive energy in time.

Embodiment 3

[0026] see image 3 , The difference between the embodiment and the embodiment 1 is that the control device 5 includes a controller 7, a liquid level gauge 9 and a timer 8, and the controller 7 is connected with the liquid level gauge 9, the timer 8 and the automatic regulating valve 6 respectively. connect. On the one hand, it is possible to set the interval target time for defoaming, and at the same time, defoaming can be carried out according to the liquid level inside the reactor 3. The combination of the two makes the defoaming more thorough. System reliability.

[0027] According to statistics, using the chlorine dioxide generation system of the present invention, the decomposition inside the generator 3 is reduced from 10 times per month to once per month, which can save 45,000 yuan in manufacturing costs per month, effectively protects the equipment, and prolongs the life of the generator. the service life of the equipment.

Abstract

The invention provides a chlorine dioxide generation system which comprises a reactant input end, a product output end, a generator and a defoaming agent tank, wherein the reactant input end, the generator and the product output end are sequentially communicated, and the defoaming agent tank is communicated with the generator. According to the chlorine dioxide generation system disclosed by the invention, foams wrapping a lot of chlorine dioxide in the reactor can be quickly defoamed, so that chlorine dioxide gas can be quickly released, a chlorine dioxide decomposition rate in the generator is effectively reduced, too much energy is prevented from being generated, and equipment is prevented from being damaged; furthermore, a production efficiency is improved, service life of the whole system is prolonged, production cost is reduced, and more environmental friendliness to the environment is achieved.

Description

technical field [0001] The invention relates to the technical field of chlorine dioxide equipment, in particular to a chlorine dioxide generating system. Background technique [0002] The chlorine dioxide generator is a vertical barrel structure container. The high-concentration sodium chlorate solution and hydrochloric acid undergo a violent chemical reaction inside the generator and at a specific temperature to generate chlorine dioxide gas: NaClO 3 +2.32HCl=0.92ClO 2 +1.16H 2 O+0.7Cl 2 +NaCl. In the production of sodium chlorate solution, it is inevitable that some organic substances such as epoxy resin in pipe materials and inorganic substances such as sulfate radicals will be brought into the generator. The existence of these impurities changes the surface tension of the solution in the generator. A large amount of foam is produced, and a large amount of chlorine dioxide gas is wrapped in the foam. If the chlorine dioxide gas cannot be released and absorbed quickly,...
