Embodiment Construction

[0010] The working principle and structure of the present invention will be further described below in conjunction with the accompanying drawings.

[0011] The constant temperature reactor provided by the present invention comprises a constant temperature aluminum tank 5 with an insulating layer 6 on the outer wall, a preheating tank 11 and a reaction tank 7 arranged in the constant temperature aluminum tank, and a first air pump 16 and a second air pump arranged outside the constant temperature aluminum tank. The air pump 18, the reaction tank is placed directly above the preheating tank, and the two tanks are supported by a bracket 10 in the middle. An electric heating tube 15 and a temperature switch 14 are installed at the bottom of the constant-temperature aluminum tank, and a constant-temperature aluminum tank temperature sensor 17 is installed on its upper part to control the temperature of the constant-temperature aluminum tank; preheating tank temperature sensors 12 ar...

Abstract

This invention refers to a constant temperature reactor that is used to fast mensurate the requirement of oxygen. In this invention, warim-up tin and retort are put in the constant temperature aluminous trough, and retort is up to warm-up tin between which there is the kickstand. There are liquid-in / out meatus and gas-in / out meatus in both warm-up tin and retort, electrical pipe and temperature transducer in warm-up tin. There are electrical pipe and temperature switch in the bottom of constant temperature aluminous trough, temperature transducer in the top, two U model unrubiginous steel tube inside one end connected to pump, the other connected to the gas-in meatus of warm-up tin and retort. The water in warm-up tin is heat and kept the constant temperature 30 degree C, then sent to retort. This constant temperature reactor completely appeases the specifically need of the temperature of water and air.

Description

technical field [0001] The invention relates to a constant temperature reaction device, which is particularly suitable for a constant temperature reactor of a reactor-type rapid biochemical oxygen demand tester. Background technique [0002] Biochemical oxygen demand (also known as BOD) refers to the amount of dissolved oxygen consumed by microorganisms to oxidize organic matter in water to inorganic matter. Through the determination of biochemical oxygen demand, the amount of biodegradable organic matter in water can be known. [0003] The standard biochemical oxygen demand measurement process includes: water sample collection, water sample oxygenation, water sample sealing in the test bottle, after a certain standard time of cultivation in the dark at 20±1°C, the measurement is after the end of the cultivation period Oxygen consumption of water samples. In countries such as the United Kingdom, the United States, and my country, this standard cultivation time is 5 days, a...
