Description

A water seal drain

technical field

The utility model relates to a drainer, in particular to a gas system waste water discharge device.

Background technique

During the transportation or treatment of dangerous gases in metallurgy, chemical industry, petroleum, natural gas and other industries, part of the water vapor will inevitably condense continuously as the gas flow rate and temperature decrease, resulting in a large amount of condensed water in the gas pipeline; or for cleaning The fan impeller, valve, etc. that transport and pressurize the above-mentioned gases are washed with water, etc., and the SO ₄ ^2- , Cl ^- , H ₂ S, etc. contained in them will cause strong chemical corrosion and electrochemical corrosion to metal components, so Containing dust will cause scaling in pipes and equipment. In order to ensure the safety of the system, various drainers are widely used to automatically discharge condensate water, flushing water and other corrosive waste water.

For the safe discharge of waste water from positive/negative pressure systems, conventional drains have been used. As shown in Figure 4, it is mainly composed of a steel cylinder, a water seal pipe, a drain pipe, a funnel, a drain valve, a drain pipe, and a water supply pipe. The prior art or similar steel drains have the following disadvantages:

1. It takes up a lot of space, and the drains are all exposed above the ground. Each drain includes a cylinder, a water-sealed pipe and at least 3 interfaces. If there are multiple drainage systems, there will be many drains. On-site The pipeline is messy, the laying is complicated, and the floor area is large.

2. The initial investment is high. In order to achieve the sealing effect, a certain water seal height must be ensured. If it is installed on the ground, the height of the ground pipeline or equipment foundation will be increased, and equipment with large vibration will affect the stability of the system.

3. High energy consumption. In severe cold, cold and hot summer and cold winter regions, in order to prevent freezing of water pipes and drains in winter, it is necessary to lay steam heat tracing or other methods along the pipes. Not only the drain itself consumes a lot of energy, but it is not conducive to energy saving and emission reduction .

4. The service life is short. Since the existing drains are all made of steel, they are prone to leakage under the scouring of highly corrosive condensed water. Although regular overflow funnels can be used to observe that the drain is full, it will require periodic inspection by personnel. There is no alarm device, once the gas leaks, it will cause serious consequences, and the average service life of the steel drain is only 6 years.

1. The design is simple, the floor space is saved, and the laying is simple, which effectively solves the shortcomings of the prior art that a drainer needs to be provided for each drainage point. The main body of the utility model is located under the ground. The exposed ground is about 0.3m, which reduces the above-ground structures and saves land occupation, and is more advantageous for multi-system and multi-drainage point situations.

2. Energy saving and emission reduction, low carbon and environmental protection. All the water-sealed pools share one replenishment pipe, which reduces the amount of water needed to replenish each drainer in the prior art. For areas that are prone to freezing in winter, waste water such as factory wastewater and waste steam can be used to replenish water in the water-sealed pool, so as to realize the recovery and utilization of waste heat and achieve the purpose of energy saving and emission reduction.

Convenient management, simple maintenance, centralized drainage of multiple drainage points, avoiding messy site, optional remote monitoring of the liquid level in the pool, the opening of the solenoid valve, the start and stop of the sewage pump, etc. The opening and closing of different water seal tanks realizes the sludge cleaning. Through the sewage outlet at the bottom of the partition wall, the mud accumulated in the water-sealed pool can be swept to the drainage pool, and then pumped away by the drainage pump, which reduces the labor intensity of maintenance personnel.

4. It is safe and reliable. Separate water seal pools are set up for drainage of different systems, which can prevent large-scale fluctuations in system pressure caused by emergencies. It can effectively deal with the situation that the instantaneous displacement exceeds the set value. The grille cover can discharge a small amount of toxic gas dissolved in water, and keep the concentration of explosive gas such as CO below the explosion limit. For the situation that there is a backup system, the drainer in the prior art can only avoid the situation that there is no water in the drainer and needs to work suddenly by continuous long-term replenishment of water. The utility model ensures that all water-sealed pools can work at any time when they are in normal operation through the setting of the height difference between the overflow hole and the drain hole.

5. Significant economic benefits. The overflow water of all water-sealed pools flows to the drainage pool, and the drainage pool is equipped with a drainage pump, that is, all water-sealed pools share one drainage pump, which reduces the initial investment and reduces the operating cost. All water-sealed pools share a solenoid valve. Since it is installed under the ground, the height of the drainage system required on the ground is reduced, and the basic investment of above-ground equipment is reduced. All gates are made of ordinary steel plates, only need to be painted with anti-corrosion paint, easy to make, easy to replace, and low in cost. The more systems and the more drainage points, the more economical it is.
