The equipment covers a small area, make full use of the structure of the plate heat exchanger and the advantages of high heat exchange efficiency, reduce the site land;

This kind of equipment has mature production process, short production cycle and safe and reliable, suitable for various high temperature conditions.

The light tube heat exchanger designed and manufactured by our company is composed of metal tube bundle and shell, through the solid wall of the heat exchange tube transfer heat from high temperature medium to low temperature medium;

Mainly used in gas-gas, gas-liquid, gas-steam medium heat transfer; The composition is relatively clean medium inside the pipe, and the other medium for heat transfer outside the pipe, the pipe side can bear high pressure, the shell side can cooperate with the cleaning process, applicable to a wide range of working conditions.

Our related products have been successfully used in power, chemical, petrochemical and other fields.

◆ Indirect heat exchange type hot blast stove, flue gas and heated gas (like air) is not in direct contact, hot air does not contain combustion particles, can meet the needs of related industries for clean hot air;

◆ Clean hot air up to 650°C;

◆ Combined with the plate heat exchanger with our invention patent (patent type: invention patent patent No. : ZL 2014 1 0844546.5), the smoke exhaust temperature is lower than 100°C, and the thermal efficiency can reach more than 94%; The equipment is a combination of combustion radiation heat transfer and convection heat transfer. The combustion chamber has the function of heat transfer at the same time. The structure is exquisite, the weight is light, the volume is small, and the installation is convenient.

◆ Waste heat from incineration can be heated according to the energy needs generated by central heating, which can heat thermal oil, hot water, air, waste gas and so on.

Catalytic combustion is a typical gas-solid phase catalytic reaction. Catalytic combustion is to reduce the activation energy of the reaction with the help of the catalyst, and enrich the reactant molecules on the surface of the catalyst to improve the reaction rate, so that the flame-less combustion at a low ignition temperature of 200-350°C, and oxidation decomposition into CO2 and H2O, and release a lot of heat.

◆ It is composed of heat exchanger, flame arrester, explosion-proof opening, heater and catalytic bed, covering an area of small, reduce pipe;

◆ Corrugated plate heat exchanger with utility model patent (patent No. : ZL 2017 2 1513114.1), good heat exchange effect, small selection of electric heater, less energy consumption during operation;

◆ The distribution device is used to ensure the uniformity of heating and the universality of catalysis.

The exhaust gas arrester is a safety device to prevent the flame spread of flammable gas and flammable liquid vapor and to prevent the explosion caused by tempering.

According to the research findings, when the flame passes through a small enough section or slit, the cooling effect of the wall and the collision effect of the active molecules will lead to the composite disappearance of the active molecules, thus destroying the conditions of the chemical chain reaction, so that the continuous combustion path cannot be formed. The flame arrester is based on the above principle of the wall effect.

Characteristics of exhaust gas arrester:

1, reasonable structure, convenient installation, easy maintenance;

2, flame arrester shell and filter element are made of stainless steel, corrosion resistant;

3, the special structure of the knitting net, the equipment resistance is small, low requirements on the system wind pressure;

4. The filter element of the equipment is made of heat-resistant stainless steel with excellent fire-resistance performance;

5, light weight equipment, exquisite structure, beautiful appearance and generous;

6, widely used in various fields of exhaust gas incineration system, all kinds of transport flammable and flammable gas pipelines, as well as explosion risk ventilation pipe mouth;
