Environmental protection monitoring system

Abstract

The invention discloses an environmental protection monitoring system. The environmental protection monitoring system comprises a housing part, a box part, and an electric part; the box part is arranged in the housing part; the top of the housing part is provided with a heat radiation layer; two side rails are arranged at the bottom of the internal part of the housing part; the two sides of the bottom of the housing part are provided with slide wheels; the front part of the box part is provided with a connecting transverse plate; the connecting transverse plate and the box part are provided with a lock; the electric part is provided with an external power supply, a breaker, a transformer, a first time relay, a first alternating current contactor, a second time alternating current contactor, a second time relay, an instrument contact, a third alternating current contactor, and a water pump. According to the environmental protection monitoring system, cooperation of the time relays and the alternating current contactors is achieved, so that start and stop of the water pump are controlled, and operation time is controlled; water supply of a sampling system is carried out at preset time, and instrument equipment normal operation is ensured; and in addition, the heat radiation layer and the slide wheels are adopted, so that device convenience is ensured.

Description

technical field [0001] The invention relates to a control box, in particular to an environmental protection monitoring system. Background technique [0002] With the country's increasing emphasis on environmental protection, under the background of accelerating the establishment of a unified national real-time online monitoring system, key pollutant discharge units in key industries with nitrogen and phosphorus emissions are required to install automatic monitoring equipment for total nitrogen and total phosphorus emissions before the end of June 2018. Network with environmental protection department. However, many manufacturers of effluent total phosphorus and total nitrogen monitoring equipment in my country use the NPW-160 automatic determination equipment of Hach Company. The NPW-160 equipment of Hach Company does not have a water supply pump system. Manufacturers who install COD and ammonia nitrogen on-line equipment generally use one water pump to supply water. Sampl...
