Preparation equipment of triazinone herbicide

Abstract

The invention provides preparation equipment of triazinone herbicide. The equipment comprises a bottom plate, an air compressor, a cooler, a crystal crushing frame structure, a condensation curing tank, a filtering and screening frame structure, a liquid outlet pipe, an atomizing nozzle, an anti-blocking air outlet pipe structure, a waste gas filtering frame structure, a water pump, a liquid conveying pipe, a distillation tank, a heating jacket, a rotating motor, a stirring frame, a feeding pipe and a steam outlet pipe. The air compressor is connected to the right side of the upper portion ofthe bottom plate through bolts. The device has the beneficial effects that through the arrangement of the calcium hypochlorite aqueous solution, the waste gas outlet pipe and the activated carbon filter screen, waste gas enters the inner side of the calcium hypochlorite aqueous solution through the waste gas outlet pipe, is filtered by the calcium hypochlorite aqueous solution, then enters the inner side of the transverse pipe and moves from the left side to the right side in the transverse pipe; the waste gas passes through the activated carbon filter screen, and harmful substances in the airare adsorbed by the activated carbon filter screen, so that the waste gas is filtered and purified, and is prevented from polluting the air environment.

Description

technical field [0001] The invention belongs to the technical field of herbicide preparation, and in particular relates to a preparation device of triazine herbicides. Background technique [0002] There are already mature net herbicide production processes in China. The main synthesis methods are: methyl mercaptan method, sodium methyl mercaptide method, sodium disulfide method and dimethyl sulfonate method, most of which are herbicides with hydrazine. The herbicide is the initial raw material, which is reacted in organic solvents such as isopropanol, n-propanol, toluene, xylene, etc. to obtain the organic solution of the net herbicide and brine layered, after liquid separation, the organic solvent is recovered by distillation and precipitating, and the organic solvent is added After washing with a certain amount of water and cooling down, the finished product is obtained by centrifuging and drying. [0003] However, the existing triazine-type herbicide preparation equipme...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a kind of preparation equipment of triazine herbicides, to solve the problem that the existing triazine herbicides preparation equipment will pollute the air environment by the gas discharged when the solution is cooled and solidified. When solidified, the crystals are easy to enter the inside of the vent pipe, which will block the vent pipe and prevent the automatic collection and crushing of the particle crystals.
