Problems solved by technology

However, biomedical wastewater also contains various solid impurities, and the sludge formed by these fixed impurities will gradually cover the surface of the electric heating rod, reducing the heat transfer efficiency between the electric heating rod and the wastewater, resulting in various types of evaporation in the prior art. Condensing equipment becomes less effective after a period of use
On the other hand, the evaporating and condensing equipment in the prior art lacks an effective sludge discharge mechanism in the evaporation tank, and the sludge accumulates at the bottom of the tank, and the deposited sludge re-integrates into the wastewater with the boiling of the wastewater, resulting in further deterioration of the wastewater treatment efficiency. reduce

Abstract

The invention discloses a biomedical wastewater treatment and purification device, which comprises an electric heating purification box, an electric heating rod, a cleaning mechanism, a condensation collection tank, a steam pipeline and a refrigeration unit; , the steam pipeline is connected to the electric heating layer and the condensate collection tank, and the refrigerating unit is connected to the condensate collection tank; the cleaning mechanism includes a linear drive, a flat plate, a scrubbing frame, a mud scraper and movable ear rods, the scrubbing frame is installed on the flat plate, and the mud scraper is hinged on the The front end of the plate and the top of the mud scraper are provided with a horizontal limit plate, and both sides of the mud scraper are provided with concave grooves, and the movable ear rods are in the shape of a broken line and are hinged in the groove; the two sides of the electric heating layer A guide rod is provided; the invention uses the bristles in the scrubbing frame to periodically clean the sludge on the surface of the electric heating rod, avoiding the reduction of the heat transfer efficiency between the electric heating rod and the waste water caused by the sludge wrapping the electric heating rod, so that the purification device can be maintained for a long time Efficient processing capacity.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to a biological medical wastewater treatment and purification device. Background technique [0002] Biomedical wastewater contains more types and quantities of bacteria than ordinary wastewater. If conventional sedimentation methods are used to treat biomedical wastewater, although sludge impurities can be purified, the killing effect on bacteria is poor. For this reason, in the prior art, the evaporative condensation method is sometimes used to treat biological medical wastewater. The basic principle is to use heating equipment (generally electric heating rods) to heat the wastewater to generate water vapor, and then recondense the water vapor into liquid water. This treatment method It can use high temperature to kill bacteria, and has a good effect on treating biological medical wastewater. However, biomedical wastewater also contains various solid impurities, a...
