Abstract
Description
Technical Field
[0001] The utility model discloses a DMDO production protection device, which belongs to the technical field of DMDO production, and specifically relates to the technical field of DMDO production protection. Background Art
[0002] DMDO, commonly known as dimethyl peroxide, is a ketone peroxide compound derived from acetone, and its molecule contains a three-membered ring system composed of peroxide chains. It is the only commonly used ketone peroxide compound, and is mainly used as an oxidant in organic synthesis. A certain amount of acetone will be produced during its production process. Acetone is flammable, volatile, and has a relatively active chemical property. At the same time, acetone is a toxic substance with moderate toxicity. Therefore, when producing dimethyl peroxide, production personnel need to perform certain protective operations. Most of the common ones are wearing protective clothing and goggles, etc. These are to prevent acetone from being poisoned. Although protection can be performed, some people will always suffer from mild acetone poisoning due to a series of reasons such as improper wearing of protective clothing and improper operation. In order to reduce the damage to personnel and ensure that the treatment of acetone is relatively economical, we proposed a DMDO production protection device. Utility Model Content
[0003] The technical problem to be solved by the utility model is to overcome the existing defects and provide a DMDO production protection device, thereby solving the problem that some people always suffer from mild acetone poisoning to a greater or lesser extent due to a series of reasons such as improper wearing of protective clothing and improper operation.
[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0005] A DMDO production protection device comprises a processing tank, wherein a mounting groove is arranged inside the processing tank, an air guide pipe is installed inside the mounting groove to guide acetone generated in the DMDO production process into the processing tank, an exhaust pipe is installed on the processing tank, and a drainage component for discharging water is installed at the bottom end of the exhaust pipe.
[0006] As a preferred technical solution of the utility model, a combustion chamber is arranged inside the processing tank, a smoke exhaust channel is arranged outside the combustion chamber, the top ends of the combustion chamber and the smoke exhaust channel are connected, the mounting groove and the combustion chamber, and the mounting groove and the smoke exhaust channel are not connected, and a gas inlet pipe and an air inlet pipe are also installed on the side of the processing tank, and the gas outlet ends of the gas inlet pipe and the air inlet pipe are both arranged inside the combustion chamber.
[0007] As a preferred technical solution of the utility model, the air duct is wound and installed in the installation groove, and an air intake connecting pipe is provided at the air intake end of the air duct, and an opening is provided on the combustion chamber at a position corresponding to the air outlet end of the air duct.
[0008] As a preferred technical solution of the utility model, the exhaust pipe is arranged at the bottom end of the smoke exhaust channel, and a solenoid valve 1 is installed on the exhaust pipe. The side of the exhaust pipe between the solenoid valve 1 and the smoke exhaust channel is connected to the interior of the combustion chamber through a return pipe, and a solenoid valve 2 is installed on the return pipe. A combustible gas monitoring sensor is installed inside the exhaust pipe between the return pipe and the smoke exhaust channel.
[0009] As a preferred technical solution of the utility model, the drainage assembly includes a drain pipe, which is connected to the bottom end of the exhaust pipe through a connecting pipe 1, and a valve 1 is installed on the connecting pipe 1. The bottom end of the combustion chamber is connected to the drain pipe through a connecting pipe 2, and a valve 2 is installed on the drain pipe.
[0010] Compared with the prior art, the utility model has the beneficial effect that the gas generated in the production process of DMDO is directly introduced into the treatment tank for combustion treatment.
