Problems solved by technology

Although this technology involves fluid transportation, the system has only one power source, and its purpose is to realize one machine with multiple functions, and the control logic of its flow regulation facility system is only used for the selection of plugs, valves or other flow regulation measures. Optimal selection involving multiple power sources and valve control and research on fluid pressure and flow

Embodiment 1

[0016] A commissioning platform for the chemical process, the principle of the mainstream system flow system figure 1 Indicated. The platform includes a air compressor 6 as a power source, a water storage tank 1, and a pump, and a heat exchanger 17 and a control system, and the air holding port of the air compressor 6 communicates with the air intake of the water tank 1, in the trachea 20 The serial air flow regulating valve 9 and the bypass air pressure regulating valve 8 are provided, and two air pressure transmitter 7 are provided on the front and rear air pipe 20 of the airflow regulator valve 9 and and the bypass air pressure regulating valve 8. The water storage tank 1 is provided with water inlet, water outlet and returns, and the water storage tank 1 is connected to water, and the water supply valve 3 and the program-controlled hydrating valve 4 are provided on the water supply pipe. The pump contains three pumps in parallel, respectively, and fixed frequency centrifugal p...

Embodiment 2

[0030] This example is a first case of a debug platform for the chemical flow of the chemical flow, which is the main research object in the inlet dielectric pressure and flow of heat exchanger 17. Closing the converter plunger pump C and the first shutoff valve 37 by cutting the air input branch (including the air compressor 6, the air flow regulating valve 9, the bypass air pressure regulating valve 8, and the air pipe 20) (cutting the first water flow bypass tube) 28), turn off the water flow bypass pressure regulating valve 18 and the water flow bypass flow regulating valve 19 (cutting the second water flow bypass pipe 29), close the second shutoff valve 38 (cutting the third water flow bypass pipe 34), will heat transfer The first inlet (heat source inlet) of the device 17 and the first outlet (heat source outlet) are directly connected to the third cutoff valve 39 (cutting the fourth water flow bypass 35) and the fourth shut-off valve 40 (cutting off the fifth water flow byp...

Embodiment 3

[0037] This embodiment is a second case of a commissioning platform for the chemical flow of the chemical flow, which is studied in the state of the storage tank 1 and the atmosphere, and the water in the storage tank 1 is self-gravity. Under the action, real-time adjustment and collection of water flow by water flow pressure valve 11 and the first flow meter 12. The second case-composed of the second seed debug platform is close to the first seed debug platform of the second embodiment, and the flow chart is image 3 Indicated (by figure 1 Equivalently), the second seed debug platform is different from the same as the first seed debug platform in Example 2:

[0038] 1) Cut the self-reciprocating input branch (including the manual hydrating valve 3 and the transpsole valve 4 thereof on the water pipe) to open the air input branch (including air compressor 6, air flow regulating valve 9, air pressure regulating valve 8 and trachea) 20).

[0039] 2) Turn off the three pumps in parall...

Abstract

The invention relates to a debugging platform for a chemical process, and belongs to the technical field of fluid conveying control. The platform comprises an air compressor, a water storage tank, pumps, a heat exchanger and a control system, the air compressor and the water storage tank form air communication and are provided with an air flow regulating valve and a bypass air pressure regulating valve, the pumps comprise at least three pumps which are connected in parallel and are connected with a first water flow bypass pipe in parallel, and the water storage tank and the pumps form liquid flow communication; the pumps and heat exchanger form liquid communication and have a bypass pressure regulating valve and a water flow regulating valve. The water storage tank is connected with tap water through a water inlet pipe, a second water flow bypass pipe is arranged between the water outlet of the pumps and the water storage tank, and the water flow regulating valve is connected with a third water flow bypass pipe in parallel. A water flow regulating valve and a back pressure valve are sequentially connected in series from the outlet of the heat exchanger to a tail end water outlet, and are respectively connected in parallel with a fourth water flow bypass pipe and a fifth water flow bypass pipe; and the air compressor, the heater of the water storage tank, the pumps, the heat exchanger and various valves are in control signal connection with the control system. Through the platform, the most reasonable fluid conveying form under different power sources for engineering application can be verified and found.

Description

Technical field [0001] The present invention relates to a debug platform for the chemical flow, which belongs to the technical field of fluid delivery control. Background technique [0002] Among the actual chemical fluid delivery engineering projects, some fluid media in the process flow is in a process node to realize some process demand, which requires strict parameter control requirements on the process node, and the control target may There are different control methods to achieve, such as the simplest media flow requires a certain value, the power source can be conveyed for mechanical pumps, other high pressure media, setting a certain medium level height relies on gravity self-flow, etc., flow regulation Method: (1) In this node, the node is set; (2) add a bypass shunt, bypass the back end, bypass, bypass, bypass the valve, by adjusting the power source parameters (such as pump, change Pump frequency speed), but which control method is most economically efficient, it is of...
