Abstract

The invention belongs to the technical field of chemical engineering, and discloses comprehensive utilization method and equipment for chemical formaldehyde and wood industry energy. According to the equipment, the lower end of a shell is provided with an air inducing opening, various formaldehyde pipelines are converged at the air inducing opening, and the formaldehyde pipelines are connected with a residual formaldehyde recovery device; a conduit opening is formed in the bottom side of the shell, a heat converter is mounted at the upper end of the shell, and a hot air outlet and a circulating pipeline are arranged at the upper end of the shell; a control box is mounted on the side surface of the shell, and a display screen and control keys are embedded in the control box; a central processing module, a communication module and a cloud server module are arranged in the control box; the air inducing opening is connected with the heat converter through a transition nozzle structure, the heat converter is connected with the circulating pipeline and the hot air outlet, and the air inducing opening is connected with a buffer tank through an introducing pipe. The problem of resource waste is solved, the cost is saved, and the utilization rate is improved.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a method and equipment for comprehensive utilization of formaldehyde in chemical industry and wood industry energy. Background technique [0002] At present, in the current density board production system, the formaldehyde production device and the wood energy are two independent workshops. Due to the certain toxicity of formaldehyde and the pollution to the environment, each workshop has to burn formaldehyde, which not only increases The cost of production has also increased the waste of energy. According to the comparison data, there are 19-21% hydrogen and traces of other components in formaldehyde. These tail gases are all new energy sources that are directly ignited. Since this part of energy is not fully utilized, It is a serious waste to make the effective gas component hydrogen, and directly venting after burning is also a pollution to the atmosphere...

Problems solved by technology

[0002] At present, in the current density board production system, the formaldehyde production device and the wood energy are two independent workshops. Due to the certain toxicity of formaldehyde and the pollution to the environment, each workshop has to burn formaldehyde, which not only increases The cost of production has also increased the waste of energy. According to the comparison data, there are 19-21% hydrogen and traces of other components in formaldehyde. These tail gases are all new energy sources that are directly ignited. Since this part of energy is not fully utilized, It is a serious waste to the effective gas component hydrogen, and directly venting after burning is also a pollution to the atmosphere

In addition, the heat-conducting oil furnace only provides heat-conducting oil for hot-pressing posts, and the flue gas generated by combustion is discharged directly after treatment, and the heat energy in the flue gas cannot be recycled.

However, glue making and MDF hot grinding jobs need a lot of steam, and fiber drying also requires steam to heat air to generate hot air to dry fibers, and the source of these steam is mainly provided by a separate boiler in the thermal energy center, which results in energy High consumption, a lot of waste of available resources

[0003] Through the above analysis, the problems and defects of the existing technology are: the formaldehyde production device and the wood energy in the prior art are two independent workshops, which makes the energy and energy connection not coherent and reasonable, resulting in a large amount of energy waste
