Sewage utilization device with good anti-blocking effect

Abstract

The invention discloses a sewage utilization device with a good anti-blocking effect, and relates to the technical field of sewage source heat pumps. The device comprises a tank body, wherein the tankbody comprises a circular shell and a conical shell; the conical shell is fixedly installed on the lower surface of the circular shell, a spiral water inlet pipe is fixedly installed on the rear sideface of the circular shell, a blow-off pipe is fixedly installed on the lower surface of the conical shell, and a sealing cover is installed on the upper surface of the circular shell through a fixing mechanism; and a cylinder is fixedly mounted on the upper surface of the sealing cover, a filter cartridge is fixedly mounted on the lower surface, corresponding to the cylinder, of the sealing cover, a water outlet pipe is fixedly mounted on the right side face of the cylinder, and a cleaning mechanism is arranged on the cylinder. The spiral water inlet pipe enables sewage in the tank body to utilize the rotational flow decontamination principle, the blockage of the filter cartridge caused by dirt and easy-to-precipitate solids can be effectively prevented, the filter cartridge and the blow-off pipe can be cleaned regularly, and the blockage of the filter cartridge and the blow-off pipe is effectively avoided, so that the device is convenient to use.

Description

technical field [0001] The invention relates to the technical field of sewage source heat pumps, in particular to a sewage utilization device with good anti-blocking effect. Background technique [0002] In the sewage source heating industry, the traditional sewage utilization method is sewage source + heat exchanger + heat pump technology. The temperature of the tail water of direct heat exchange is generally 7°C. The heat source side is for the maximum utilization of sewage resources. The general design is 8°C. Due to the heat exchange requirements and the characteristics of the host, the inlet and outlet water temperature of the general host is designed to be 12 / 5°C. The average temperature of the heat pump host is lower, and the energy efficiency of the system is relatively small. If the inlet and outlet water temperature is increased, the sewage backwater cannot be controlled. Temperature, it is difficult to maximize the utilization of sewage resources. The user-side he...
