Description

A kind of anti-shock separation tank with baffle

technical field

The utility model relates to a separation tank, in particular to a shock-proof separation tank with a baffle plate which can prevent water hammer from occurring.

Background technique

With the rapid development of modern industry, more and more attention has been paid to the utilization of energy. The relatively cheap steam energy has been widely used in all walks of life. The waste heat recovery of steam condensate and the cascaded utilization of secondary steam are the key factors for enterprises to improve the comprehensive energy efficiency of steam systems. And the best way to save energy, reduce consumption and increase efficiency. The recovery of condensed water and secondary steam and the delivery of fresh steam are all carried by pipelines. In the process of transportation, it is a common problem to raise the condensed water or steam to the required height, and the general design and construction adopt the method of connecting with the same diameter elbow to raise the pipeline. In this way, steam and condensed water are pushed upward or forward along the pipeline under the action of pressure difference, and there is a phenomenon of water hammer under the action of two-phase flow. Thus there is a risk of damaging the equipment and affecting normal production.

Chinese patent CN101972576A discloses a steam-water separation tank, which includes a tank body, an air inlet on one side of the tank body, an air outlet on the other side, and a water outlet on the bottom of the tank body. In order to improve safety, a safety valve is installed on the top of the tank. The utility model connects all the outlets of the steam pipes and connects them to the steam-water separation tank. After the residual steam enters the steam-water separation tank, it is converted into water and steam. After the water is collected, it can be used for analysis and added to the heating system, etc., and the steam is connected to the equipment or places that need to be heated, such as: heating pools, heating greenhouses, etc.

Chinese patent CN202909594U discloses a novel steam-water separation tank, which includes a main body of the separation tank. The main body of the separation tank has a vertical structure. An external steam inlet is provided on the wall, and a cyclone separation cylinder is provided at a position corresponding to the external steam inlet inside the main body of the separation tank. A conical separation plate is provided above the cyclone separation cylinder, and a circular Cylinder separator: The steam generated by direct separation method has a dehydration rate of ≥96%, which can meet the needs of power generation and subsequent VD furnace use. The steam is directly separated in the water separation tank, and the steam supply and distribution are even, and the steam supply is continuous and stable without consumption. External mechanical power can effectively improve the quality of steam and the recovery and utilization rate of waste heat, and generate greater economic and social benefits.

Chinese patent CN202909554U discloses a horizontal steam vapor-liquid separation tank, including a separation tank body, the separation tank body is horizontally arranged, a saddle is provided under the separation tank body, and a mixing tank is provided at the bottom of the separation tank body. Steam inlet and liquid outlet, the connecting pipe installed on the mixed steam inlet extends into the inside of the separation tank body, the upper part of the separation tank is provided with a steam outlet, and the lower part of the steam outlet is provided with a gas-liquid separation device; the structure is simple, easy to use, Sturdy and solid, it can continuously and efficiently exhaust steam without consuming external mechanical power, and can effectively improve the quality of steam and the recovery and utilization rate of waste heat.

Detailed ways

Referring to Fig. 1, the utility model embodiment is provided with inlet pipe 1, separation tank body 2, left baffle plate group 41, right baffle plate group 42, drainage or sewage pipe 5. The inlet pipe 1 is welded to the side of the separation tank body 2, and one end of the left baffle plate group 41 and the right baffle plate group 42 are respectively welded on the left and right chamber walls of the upper cavity in the separation tank body 2, and the left baffle plate group 41 and The right baffle plate group 42 is arranged alternately and parallel to each other, and the hydrophobic or sewage pipe 5 is welded to the bottom of the separation tank body 2 .

The working principle of the utility model is as follows:

In the steam delivery mode, when the steam and condensed water enter the cavity of the separation tank 2, the water mist in the steam impacts the left baffle group 41 and the right baffle group 42 on the upper part of the separation tank 2 cavity along with the flow velocity of the steam The moisture in the steam is separated, and the separated high-quality steam enters the conveying pipeline through the top nozzle; the water mist impacting the left baffle group 41 and the right baffle group 42 is separated to form water droplets, which gather in the inner cavity of the separation tank 2 The lower part is discharged through the hydrophobic or sewage pipe 5 at the bottom. In this way, it plays the role of a separation tank in the steam transportation process to separate the moisture in the steam, thereby improving the quality of the steam and avoiding the occurrence of water hammer during the transportation process.
