a. Production process of glass lined reactor

The Glass lined reactor is a kind of industrial enamel product. It is formed by the high silicon content glass enamel enamel through the high-temperature enamel of about 900 ℃, so that the glass enamel is evenly and tightly attached to the surface of the metal substrate. A composite product with dual advantages of strength and glass corrosion resistance, its specific production process is as follows:

1. When making the Glass lined reactor, first press the steel plate with a mold into a baffle that meets the requirements of the reaction tank. The width of the baffle should be one-eighth to one-sixth of the reaction tank, and then the baffle According to the size of the equipment, it is folded into one or more layers, and then welded to its inner wall for enamelling.

2. The dry mix, welding rod and enamel used to produce the Glass lined reactor must be of high quality. The steel plate should have a tight inner lattice structure and trace elements, because it can inhibit hydrogen absorption. For the enamel, choose the enamel with good corrosion resistance, excellent temperature resistance and low melting point.

3. Enameling in the Glass lined reactor adopts the firing process of "low temperature long firing" and "slow cooling after enamel firing". The reaction tank has no pores after enameling three times, and the subsequent enameling just increases the thickness of the enamel layer. , So it has good corrosion resistance, friction resistance, and collision resistance.

The quality of an Glass lined reactor is directly related to the production process of the equipment. Therefore, understanding the production process of the equipment will help us choose better quality products. I hope that the above content can help users choose the right one.

b. Temperature heating method of glass lined reactor

Glass lined reactors need temperature coordination during use, because most chemical reactions need to be carried out under certain temperature conditions, so we need to understand the heating method of the equipment temperature to ensure the normal use of the equipment.

1. Water heating method of glass lined reactor

When the reaction temperature of the reactor is not high, we can use water heating for heating-this type of heating system has two types: open and closed: the open heating system is relatively simple, mainly composed of circulating pumps, water tanks and pipes And the regulator that controls the valve; and when high-pressure water is used, the reactor requires high mechanical strength, so a coiled tube must be welded on its outer surface. The gap between the coiled tube and the tank wall will increase the thermal resistance and reduce the heat transfer effect.

2. Steam heating method of glass lined reactor

If the equipment requires heating temperature below 100 degrees Celsius, it can be heated with steam below one atmospheric pressure; when the heating temperature is within the range of 100 to 180 degrees Celsius, saturated steam can be used; when the temperature is higher, high pressure superheated steam should be used.

3, other medium heating of glass lined reactor

If the process of the reaction medium in the reactor must be operated at high temperature or to avoid the use of high-pressure heating systems, other media can be used instead of water and steam, such as mineral oil (275~300°C), mixed with diphenyl ether ( Boiling point: 258℃), molten salt (140~540℃) and liquid lead (melting point: 327℃), etc.

4. Electric heating method of glass lined reactor

The resistance wire is wound on the insulating layer of the whole body of the reactor or installed on a special insulator some distance away from the reactor, so a small space gap is formed between the resistance wire and the reactor body.

Therefore, from a technological point of view, the glass lined reactor must be able to withstand pressure and temperature changes, so as to better improve equipment efficiency and service life.

c. Technical points

Glass lined reactors are mostly used for the reaction of corrosive materials, so the requirements for enamel are very high. Our company adopts Czech enamel, according to advanced powder spraying and firing technology, to ensure the reliability of the quality of each product.
