Embodiment 1

[0041] A COD digester such as figure 1 As shown, it includes a base 1 , a bracket 2 fixed on the base 1 , and a mounting base 3 fixed above the bracket 2 . A heating electric furnace plate 4 is arranged on the base 1, and a digestion bottle 5 is placed on the electric furnace plate. The heating electric furnace plate 4 is used to heat the digestion bottle 5 after being energized. The bracket 2 is four uprights distributed in four squares, and the uprights are fixedly connected to the front and rear surfaces of the mounting seat 3 . The mounting base 3 is provided with a plurality of mounting holes 6 along the vertical direction. The mounting holes 6 are provided with a reflux condenser pipe 7 , and the lower end of the reflux condenser pipe 7 is connected to the digestion bottle 5 .

[0042] like figure 2 , image 3 As shown, the reflux condenser tube 7 is arranged in a circular tube shape, and the lower end of the reflux condenser tube 7 is arranged in a tapered manner, w...

Embodiment 2

[0049] A method of using a COD digester, comprising the following steps:

[0050] S1, plug the lower end of the reflux condenser tube 7 with a plug, insert the lower end of the reflux condenser tube 7 into the cooling liquid, so that the cooling liquid is filled into the groove 11, then take out the reflux condenser tube 7, and insert the lower end of the reflux condenser tube 7 into the cooling liquid. Remove the plug after cleaning the outer wall;

[0051] S2, the liquid to be detected is added into the digestion bottle 5, and then placed on the top of the heating electric furnace plate 4, and then the reflux condenser tube 7 is passed through the installation hole 6, so that the lower end of the reflux condenser tube 7 is inserted into the digestion bottle 5 and the digestion bottle 5. Sealing connection, adjust the height of the lower shell 32 through the adjustment assembly 12, so that the lower end surface of the lower shell 32 is higher than the mouth of the digestion b...

Abstract

The invention discloses a COD digester, which relates to the field of water sample detection equipment. The technical solution includes a base, a bracket arranged on the base and a mounting seat arranged above the bracket. The base is provided with a heating electric furnace plate, an electric furnace plate. A digestion bottle is placed on top, a number of mounting holes are opened on the mounting seat along the vertical direction, and a reflux condenser tube is arranged on the mounting hole, and the lower end of the reflux condenser tube is connected with the digestion bottle. There is a cooling fan, and the cooling fan is used to blow air toward the reflux condenser pipe for heat dissipation, and both ends of the mounting seat along the air blowing direction of the cooling fan are provided with ventilation holes. The cooling fan blows air to cool the reflux condenser in time, so that the condensation effect of the reflux condenser is more stable.

Description

technical field [0001] The invention relates to the field of water sample detection equipment, and more particularly, to a COD digester and a method for using the same. Background technique [0002] In the field of environmental protection, chemical oxygen demand (COD) is one of the main control indicators of surface water and wastewater, and an important comprehensive indicator of organic pollution of water. [0003] The instruments used by environmental protection monitoring agencies to detect sewage usually include COD digesters. COD digesters are mainly used to degrade difficult-to-measure substances and convert them into easy-to-measure compounds or ions. The COD digester is generally composed of a main engine, a bracket and a base. A heating electric furnace plate is installed on the base, and a digestion bottle is placed on the electric furnace plate. The digestion bottle is connected to the reflux condenser. [0004] During the use of the above COD digester, the con...
