Abstract

The invention discloses a chemical gas desulfurization device based on PLC control. The chemical gas desulfurization device based on PLC control comprises a water inlet pipe, an air inlet valve, an air inlet pipe, a water cooling chamber, a heat absorption water pipe, a water cooling chamber, a water pump, a cold water recovery cavity, a water pumping pipe, a cooling tank, a cold water recovery pipe, a cooling water uniform distribution cavity, a desulfurization chamber, a desulfurization cavity, a desulfurizing agent spraying disc, a desulfurizing pipe, an air outlet pipe, a PLC, a base, a liquid outlet valve and a liquid outlet pipe; the water cooling chamber and the desulfurization cavity are arranged on the upper end surface of the base, and the water cooling chamber is located on theleft side of the desulfurization cavity; the cold water uniform distribution cavity is formed in the top of the water cooling chamber, and the cold water distribution cavity is connected with the water inlet pipe; the heat absorption water pipe is uniformly distributed in the middle of the water cooling cavity, the top of the heat absorption water pipe is in communication with the cold water uniform distribution cavity, and the bottom of the heat absorption water pipe is in communication with the cold water recovery cavity. The chemical gas desulfurization device is reasonable in structural design, so that the chemical gas can be subjected to cooling treatment, desulfurization treatment can be carried out, and the chemical gas desulfurization device is good in desulfurization effect and convenient to operate through the control operation of the PLC.

Description

technical field [0001] The invention relates to the field of desulfurization equipment, in particular to a chemical gas desulfurization device based on PLC control. Background technique [0002] In recent years, the problem of air pollution has become more and more serious, and the air quality has been deteriorating day by day. Environmental problems are directly related to people's health and living standards. Therefore, people's desire for environmental governance is unprecedentedly strong, and environmental protection awareness has gradually penetrated into the hearts of the people. Environmental protection facilities in various industries are gradually improving, but the technical effect still needs to be improved; in the process of purifying chemical flue gas, it is generally necessary to desulfurize the flue gas, and the temperature of chemical gas is generally around 200°C, which needs to be cooled first; in addition With the increasingly stringent environmental prote...

Problems solved by technology

Environmental protection facilities in various industries are gradually improving, but the technical effect still needs to be improved; in the process of purifying chemical flue gas, it is generally necessary to desulfurize the flue gas, and the temperature of chemical gas is generally around 200°C, which needs to be cooled first; in addition With the increasingly stringent environmental protection requirements, the treatment efficiency of wet desulfurization (generally around 60%) gradually cannot meet the latest emission standards, and further improvement is needed. Therefore, this application proposes a chemical gas desulfurization device based on PLC control
