Embodiment 1

[0033] This embodiment is basically as attached figure 1 Shown: a circulating water dynamic simulation experiment device suitable for microbial preparations, which is a dual-water circuit process, consisting of five parts: a simulated heat exchange system, a cooling tower system, an atmospheric saturated steam system, a process control system, and a water system. Including the replenishment tank 1, the volume of the replenishment tank 1 is 50L, at least satisfying the replenishment capacity of 12 hours, and the automatic replenishment is controlled by the float valve. The replenishment tank 1 is connected with a water storage tank 2 through a pipeline, and the capacity of the water storage tank 2 is 60-200L (adjustable). The biological filler is fixed in the water storage tank 2. The biological filler in the present embodiment is a fiber ball filler, which is more conducive to the growth of microorganisms. attached. The water storage tank 2 is provided with a baffle, and the ...

Embodiment 2

[0039] Such as figure 2 As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, the fan 17 is electrically connected to an electric control cabinet 15, and the electric control cabinet 15 is provided with a PLC control system and a touch screen 16, and the touch screen 16 is fixed on the electric control cabinet. The exterior of cabinet 15. Both the steam generator 10 and the condenser 12 are fixed with temperature sensors, and the temperature sensors are connected with the electric control cabinet 15 through signals. Specifically, the temperature detection element in the condenser 12 is a platinum thermal resistance Pt100 with a range of 0-70°C and a control accuracy of ±0.1°C, connected to the electric control cabinet 15 by a signal line. Steam temperature detection element: platinum thermal resistance Pt100, measuring range 0-120°C, detection accuracy ±0.1°C, connected to the electric control cabinet 15 by a signal line.

Abstract

The invention relates to the field of circulating cooling water systems, and discloses a circulating water dynamic simulation experiment device suitable for a microbial preparation. The circulating water dynamic simulation experiment device comprises a water supplementing tank and a water storage tank connected with the water supplementing tank, a biological filler is arranged in the water storage tank, a baffle is connected in the water storage tank, and the baffle directly faces a water outlet of the water storage tank; and a water outlet of the water storage tank communicates with a precipitation well, the precipitation well is sequentially connected with a water pump, an inlet piece hanging device, a high-pressure saturated steam system and an outlet piece hanging device, the outlet piece hanging device is connected with a cooling tower, and the cooling tower is connected with the water storage tank. By arranging the biological filler, on one hand, microorganisms can be attached to form a biological membrane, and on the other hand, the hydraulic retention time of a fungicide in the water storage tank is conveniently prolonged, and the pollutant degradation effect is enhanced; and the problems that an existing device is not suitable for dosing of microbial preparations, flocculation bacteria are prone to blockage after sedimentation, microbial agents are short in retention time and not suitable for degradation, and a system is not suitable for growth of various bacteria are solved. The circulating water dynamic simulation experiment device is suitable for popularization and usage.

Description

technical field [0001] The invention relates to the field of circulating cooling water systems, in particular to a circulating water dynamic simulation experiment device suitable for microbial preparations. Background technique [0002] With the rapid development of industry in recent years, the water consumption of industrial enterprises has increased greatly. Among them, the circulating cooling water system generally accounts for more than 60% of industrial water consumption, and the electricity, chemical and other industries have reached 70%-80%. During the evaporation process, the ion concentration of the cooling water increases, and at the same time it contacts with the outside air. Microorganisms and other pollutants in the air also continuously enter the system, causing problems such as bacteria and algae outbreaks, scaling, and corrosion in the circulating water system. Traditional treatment methods such as adding phosphorus-containing chemicals and biocides will cau...
