I. Product overview

CHNQ closed condensate water recovery device is a new type of closed condensate water recovery device developed by our company after many years of practical experience. The system is designed according to the basic principles of fluid dynamics, gas-liquid two-phase flow, mass and heat transfer, and is a high-tech product of mechatronics. Completely eliminate the conditions of cavitation and steam plug production of high temperature condensate pump, and effectively prevent pressure and secondary flash steam from bubbling out, achieve closed recovery of condensate water and secondary steam, prevent secondary oxygen dissolution of condensate water, energy saving and water saving, environmental protection effect is obvious. It has the characteristics of low noise, easy operation, reliable operation and high degree of automation. Widely used in petroleum, chemical, electric power, metallurgy, paper making, pharmaceutical, rubber, food, beverage, light industry, heating and other industries in the production of steam use occasions, as well as hotels, restaurants, hospitals and other civil buildings steam condensate recovery.

Ⅱ, the working principle

According to the characteristics of two-phase flow of steam and water, condensed water enters the recovery device. Then the continuous adjustment of the automatic decontamination device and the pressure regulating system makes the soda water in a relatively stable state, creating the necessary conditions for the recovery of high temperature condensate water. The flow state of the high temperature water at the pump inlet is adjusted by the pressure regulating system and cavitation elimination device, so that the high temperature condensate water at the pump inlet is always in a single-phase micro supercooling state, thus eliminating the inducement of cavitation in the pump. It has complete start, stop, level control, automatic manual switching and alarm functions. According to the actual requirements of production, the liquid level automatic control system is used to rationally allocate the high-temperature condensate water in the condensate water recovery unit, so that the production process equipment and the condensate water system can run safely and smoothly.

The device is composed of condensing water tank, condensate pump, decontamination device, cavitation elimination device, liquid level controller and control cabinet, etc.

Ⅲ, product advantages

1) After the closed recovery of the steam and condensate, the production cost of the enterprise is reduced, and the competitiveness of the market and the net profit of the enterprise are improved.

2) After the recovery of the steam and condensate, the thermal pollution caused by the discharge of condensate and flash secondary steam is completely eliminated, and no white steam floats in the atmosphere to avoid thermal pollution and achieve clean production.

3) condensate will not be re-polluted by oxygen in the air, and can be directly used to save deoxygenated water.

4) The condensate pump does not cavitation in the state of conveying high temperature condensate, and can send the condensate to the designated place.

5), the system is balanced and stable, and the condensate recovery device is fully automatic and continuous operation.

Ⅳ, product characteristics

1) Energy saving and water saving

1, closed recovery of high temperature condensate, no secondary flash steam and hydrophobic leakage, steam condensate contained in the full recovery of heat energy, water can make the system thermal efficiency increased by 15-30%;

(2) Compared with the open return water system, the return water rate is increased by 10-30%, up to more than 97%;

③, can save fuel 20~ 30%, improve energy efficiency up to 21%;

(4) Reduce the amount of pollution by 20-25%, greatly reducing the emissions of harmful substances such as S02, C02 and smoke, reducing air pollution and protecting the environment.

2) Elimination of cavitation: the closed circuit recovery device is provided with cavitation elimination device to prevent the pump from cavitation, so that the condensate recovery system runs in high temperature closed.

3), high degree of automation: the use of automatic control of opening and closing, automatic alarm, double pump automatic switching and other measures to form a variety of functions integrated closed recovery automatic management, reliable operation.

4), small size: the use of circular tank structure, mechatronics, compact structure, small size, small footprint, extremely wide use.

5), long service life: to solve the corrosion and damage of cavitation and oxygen corrosion to the equipment, with safety devices and pressure regulating devices, to ensure the closed recovery of condensed water of various parameters and the normal operation of water.
