FAQ - Wuxi Hengda Chemical Machinery Co., Ltd.

1. Q: What parameters are required for reactor selection?

A: First, we need to clarify the size of the reactor, the reaction temperature of the material, the corrosion of the material, the pressure required for the reaction and other parameters.

2. Q: What are the heating (cooling) methods for the reactor?

A: There are three main heating (cooling) methods for the reactor: inner coil, jacket, and semiattached pipe. Among them, the inner coil is in direct contact with the material, and the heating (cooling) effect is good. If there is no need to consider the problem of material residue, it is the preferred solution.

3. Q: How to choose the stirring method of the reactor?

A: The stirring method of the reactor is mainly determined by the characteristics and viscosity of the material. Materials are usually divided into solid materials and liquid materials. Our company will customize different types of stirring methods according to customer needs to ensure more efficient material mixing.

4. Q: How to select a heat exchanger?

A: The heat exchanger needs to be selected according to customer requirements and working conditions, such as shellandtube, Utube or spiral plate heat exchanger; at the same time, the actual situation will be combined to determine what materials flow through the tube side and shell side of the heat exchanger.

5. Q: What should be considered in the design of the heat exchanger?

A:The process parameters required by the customer should be considered, such as: heating (cooling) the material from a certain temperature to the target temperature within a specified time, and the pressure that the equipment needs to withstand.

6. Q: What should be considered in the design of the storage tank?

A: Factors such as equipment material, material temperature, corrosion, and whether there is pressure should be considered.

7. Q: What supporting auxiliary equipment is needed to build a new resin plant?

A: The construction of a resin plant is a combination of multiple systems, which requires comprehensive consideration. The following points need to be focused on:

Heat source system: choose steam or heat transfer oil, and the fuel of the corresponding boiler (diesel or natural gas);

Cooling system: cooling water can be directly introduced into the reaction equipment, or the hot oil can be cooled by a heat exchanger to obtain cold oil for cooling;

Feeding system: liquid materials can be directly fed into the kettle through a mass flow meter, or fed into the kettle through a weighing module (using a highlevel weighing metering method), or the two methods can be combined;

Waste gas and wastewater treatment system: generally divided into biochemical treatment and incineration treatment. Incineration treatment includes directfired TO furnaces and regenerative RTO furnaces. Incinerators can realize waste heat recovery and replace some boiler functions;

Vacuum system: vacuum pump selection is required;

Gas source system: including nitrogen and compressed air. Nitrogen, as an inert gas in the reaction, needs to be involved in the whole process; compressed air is the power source of all automatic pneumatic valves and is also crucial.
