Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] Such as Figure 1 to Figure 6 As shown, a hospital sewer residual mercury monitoring and early warning device includes a housing 2 installed at the outlet of the bottom of the sewer elbow 1, and a filter screen 3 is also provided between the top of the housing 2 and the bottom of the sewer elbow 1. The bottom of the housing 2 is provided with a coaxial cable 4, the bottom of the side wall of the housing 2 is provided with a sewage pipeline 5, and the sewage pipeline 5 is provided with a valve 6; in this embodiment, the filter screen 3 is made of wire The material is metal chromium, which has good anti-corrosion performance. The filter mesh size of the above-mentioned filter is 10 mesh, ("mesh" is a measurement unit of the filter mesh size, which refers to 1 inch (25.4 mm) In terms of length, how many holes are there. The large...

Abstract

The invention provides a hospital sewer residual mercury monitoring and pre-warning device. The device comprises a shell installed at an outlet in the bottom of a sewer bent pipe, a filter screen is arranged between the top of the shell and the bottom of the sewer bent pope, coaxial cables are arranged at the bottom of the shell, and a pollutant discharge pipeline is arranged at the bottom of the side wall of the shell and provided with a valve. Conductive layers and insulating layers on the upper portions of the coaxial cables are distributed in a step shape, and the output ends on the lower portions of the coaxial cables are connected with an LED light source system through an electromagnetic control mechanism. By means of the device, residual liquid mercury of a hospital sewer can be effectively monitored and discharged out of the sewer in time, and environment pollution is avoided.

Description

technical field [0001] The invention relates to the technical field of mercury monitoring, in particular to a monitoring and early warning device for residual mercury in hospital sewers. Background technique [0002] Mercury is the only metal in the world that is in a liquid state at normal temperature and pressure. It has a silver appearance and can flow like water. It is one of the metals widely used in scientific research, industry, and agricultural production. Mercury thermometers are widely used in hospitals. The advantages of mercury thermometers are low cost, accurate and stable measurement results, and the disadvantages are that it is difficult to read and is fragile. Once broken, mercury is toxic to the human body. Mercury vapor is highly toxic. If it is inhaled through the respiratory tract for a long time, it will Can cause different degrees of acute and chronic poisoning, and mercury is a heavy metal, which is difficult to remove after entering the water environm...
