Condensate recovery system without trap

1. <overview>

Also known as: Centralized drainage condensate recovery system without traps.

It is specially developed for the working conditions of condensate recovery by using thermal equipment for group drainage. It completely solves the problems of air, stagnant water, trap leakage, and clever use of flash steam. The entire steam thermal system considers condensate recovery, which is different from the traditional condensate closed recovery device on the market, which eliminates the waste of condensate.

It has been widely used in industrial production fields such as oil, starch, papermaking, pharmaceutical, chemical industry, rubber, printing and dyeing, tobacco, food processing, gypsum board, and wood board processing.

2. <structure>

The entire system consists of a centralized drainage subsystem, a secondary steam reuse subsystem, and a high-temperature condensate recovery subsystem.

Structure diagram

2.1 Concentrated hydrophobic subsystem

This subsystem terminates the drainage method of each trap with a trap valve. Based on the principle of micro differential pressure and micro-undercooling, a special steam trap device is used to condense water, air and non-condensation The gas is quickly and completely discharged from the heat exchange equipment of different pressures in a timely and thorough manner (as can be seen from the subcooling degree), which ensures better heat exchange efficiency and effect of the heat exchange equipment. The pressure regulating system of the system is used to ensure that the pressure of the return water pipeline is lower than the pressure of each steam-using equipment, so that all steam-using equipment is drained and unobstructed, and the interference of returning water (from water hammer, air resistance, and subcooling) (See other aspects), so that the condensate from all channels with different pressures can be returned to the condensed water centralized drainage device, and finally concentrated drainage and exhausted in the centralized drainage device.

2.2 Flash steam utilization subsystem

The condensed water centralized drainage device separates the gas-liquid two-phase mixture recovered by each heat exchange equipment in an orderly manner:

2.3 Condensate delivery system

After the flash steam extraction in the centralized drainage device, the high-temperature condensate is controlled by the liquid level transmission signal, and the high-temperature condensate is directly sent to the steam pressure of the boiler through the high-temperature anti-cavitation pump (which can be directly seen from the service life of the pump). Package for direct use by the boiler, making full use of the value of condensate. Increase the boiler make-up water temperature, reduce water treatment costs, and reduce the boiler's blowdown rate.

4.1 Exhaust technology

This steam breaking method is equipped with a steam trap for each steam-using equipment. The special steam-blocking device is used to make the high-temperature condensate, air, and non-condensable gas of the heat exchange equipment quickly, thoroughly, and timely. The exhaust of steam equipment can ensure the steam space in the steam equipment to a large extent, eliminate the steam resistance and poor drainage of the steam thermal system, avoid the single relative flow sensible heat release, improve the steam heat transfer efficiency, and the equipment heats up fast. It solves the problem of contradiction between energy saving and heat exchange caused by the often-opened bypass of steam equipment due to poor heating effect, and also solves the leakage problem of traditional traps.

4.2 High and low voltage common network recovery technology

High and low pressure common network is a difficult problem of closed recovery technology. The condensate water discharged from heat exchange equipment with different pressures makes the pressure of the recovery pipeline network different, which is prone to vapor resistance and water hammer. It also causes low pressure heat exchange equipment due to back pressure. High and produce poor water-repellent, making the equipment unable to use normally.

The return water lines of heat exchange equipment with different pressures are divided into two types of high-pressure and low-pressure recovery lines, which enter the high-pressure and low-pressure inlets on the recovery host, respectively. The high-low pressure balance device smoothly condenses the entire system to the centralized drainage system. Device. The system's proprietary technology enables high and low pressure to be connected to the network, and the return water does not interfere. It avoids various problems of traditional condensate with different pressures in the recovery pipe network, ensures that the condensate from heat exchange equipment with different pressure and gas parameters is smoothly discharged, and ensures production equipment. Normal operation.

4.3 Flash steam extraction treatment technology

At present, many closed recovery devices on the market only return condensate directly to the boiler. Due to the loss of pipeline heat and the thermal efficiency of the boiler, the effective heat is only about 58%.

The low-quality flash steam in the centralized drainage device is extracted by using our company's proprietary technology to boost and dry the flash steam, so that the low-quality flash steam saturated steam meets the technical requirements of the saturated steam, and is injected into the steam supply pipeline. reuse. Flash steam is used on site to avoid flash loss or heat loss through boiler circulation; save steam by 5% -10% and reduce boiler steam supply pressure.
