Description

Technical Field

[0001] This utility model relates to a treatment device for the precipitation of lithium chloride crystals in waste liquid. Background Technology

[0002] Among the methods for preparing lithium chloride crystals, distillation is the most environmentally friendly method, generating the least amount of wastewater. For example, Chinese invention patent application CN105001101A discloses a method for synthesizing 4-chloro-2-trifluoroacetylaniline hydrate hydrochloride. A solution of n-butyllithium is added dropwise to a solution of 4-chloro-N-pentanoylaniline at low temperature to obtain a bislithium salt solution of 4-chloro-N-pentanoylaniline. Then, trifluoroacetyl chloride gas is introduced into the solution at low temperature to react and obtain... The synthesis proceeds to 4-chloro-2-trifluoroacetyl-N-pentanoylaniline, which is then hydrolyzed under acidic conditions to yield 4-chloro-2-trifluoroacetylaniline hydrate hydrochloride. This invention uses n-butyllithium as a base, and after neutralization with hydrochloric acid, it is essentially converted into a lithium chloride solution with relatively high economic value. However, this synthesis method requires drying the lithium chloride solution in the waste liquid to obtain lithium chloride crystals. Nevertheless, this method has the following drawbacks:

[0003] 1. The water vapor generated during the distillation process is directly emitted, and the resulting waste gas will cause a certain degree of air pollution;

[0004] 2. Distillation produces a large amount of water vapor, which increases the humidity in the room and affects people's health. Although there is an exhaust fan, the more water vapor there is, the greater the exhaust force required, which increases the exhaust burden and energy consumption. Utility Model Content

[0005] In view of the above, this utility model provides a treatment device for the precipitation of lithium chloride crystals in waste liquid, so as to solve the problems existing in the prior art.

[0006] According to one aspect of the present invention, a treatment device for the precipitation of lithium chloride crystals in waste liquid is provided, including a shell, a collection component for collecting water vapor during the crystallization process and condensing the water vapor into water, and an adsorption component for adsorbing waste gas. The collection component is connected to the top of the shell, and the adsorption component is connected to the exhaust end of the collection component.

[0007] The shell contains a stirring rod, the bottom of the shell contains a motor, the bottom of the shell contains a heating element and a support frame for heating the shell, the lower end of the stirring rod passes through the bottom of the shell and is connected to the rotating end of the motor, and the stirring rod is rotatably and sealingly connected to the bottom of the shell.

[0008] The collection assembly includes a collection hood, a collection bucket that allows water vapor to condense into water, and a transport pipe that transports water vapor from inside the shell to the collection bucket. The collection hood is located on top of the shell, the collection bucket is located on one side outside the shell, and one end of the transport pipe is connected to the middle of the collection hood, while the other end is connected to the upper side of the collection bucket.

[0009] The bottom of the collection tank is also equipped with a return component that can return the collected water to the shell for cleaning the shell.

[0010] Preferably, the adsorption assembly includes an activated carbon adsorption layer, and an exhaust pipe is provided on the upper side of the collection tank, with the activated carbon adsorption layer disposed inside the exhaust pipe.

[0011] Preferably, the reflux assembly includes a water pump and a reflux water pipe.

[0012] Preferably, the collection bucket is made of stainless steel.

[0013] Preferably, the collection cover is detachably placed at the top outlet of the housing.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. By collecting water vapor, the water vapor is prevented from escaping. After the water vapor enters the collection tank, it will condense on the outer wall of the collection tank and fall to the bottom of the tank. The condensed water can be used to clean the shell, which is more environmentally friendly.

[0016] 2. After the water vapor passes through the collection tank, the gaseous water condenses into liquid water, and the remaining waste gas components are discharged after being adsorbed by the exhaust pipe, greatly reducing the harmful components of the waste gas. Attached Figure Description
