specific Embodiment approach

[0026] Its specific implementation is as follows:

[0027] Assuming that the fumigation process takes 30 hours, each tunnel 102 in the fumigation storehouse 101 is designed to hold 8 trolleys 111 , the middle 6 trolleys are located in the fumigation section 104 , and there is one trolley in the preheating section 103 and desorption section 105 . Open the fumigation warehouse automatic door 116 every 5 hours.

[0028] 1. Prepare water, electricity, boiler and other auxiliary facilities to ensure the normal operation of the equipment. The internal air circulation fan 106 and the partition air curtain 107 are turned on.

[0029] 2. Load materials to the trolley 111, open the gates at both ends of a tunnel to feed materials, at this time the exhaust system 110 is opened to a large air volume, and the air curtain 118 at the gate is opened to prevent the leakage of toxic gas under the action of negative pressure and air curtain.

[0030] 3. The trolley 111 enters the preheating se...

Abstract

The invention discloses a wood fumigation quarantine and disinfection system, which comprises a fumigation chamber and a wood transfer system, wherein the fumigation chamber is a tunnel type building, and comprises a preheating section, a fumigation section and a desorption section; horizontal counter-blowing air curtains are arranged between every two sections and at inlets and outlets of tunnels; an air circulation system and an exhaust system are arranged in the fumigation section; an air outlet of the exhaust system is positioned in the top of the fumigation section, and is connected with an exhaust absorption and rectification system; the exhaust absorption and rectification system comprises an absorption tower and a rectification tower; an air inlet with an airtight valve and an activated carbon filtering device is formed in the outer wall of the desorption section; the wood transfer system comprises a rail arranged on the ground in and outside the fumigation chamber and a rail trolley on the rail. The wood fumigation quarantine and disinfection system can be used for performing automatic assembly line fumigation treatment on imported logs in a large scale, so that the quarantine and disinfection working efficiency is improved; in addition, the quarantine and disinfection requirements are met, and meanwhile, a treatment process is more efficient, energy-saving and environment-friendly and safer.

Description

technical field [0001] The invention relates to a wood quarantine and pest elimination system, in particular to a wood fumigation quarantine and pest elimination system. Background technique [0002] With the rapid development of my country's economy, the demand for wood and other products in the domestic market continues to grow. According to customs statistics, from 2010 to 2012, my country imported more than 34 million m of logs per year 3 , with a value of more than 6 billion U.S. dollars; a total of more than 114.57 million m in three years 3 , with a value of US$21.6 billion. It is estimated that by 2015, the domestic demand for construction timber will be about 380 million m 3 , the domestic gap will reach 120 million m 3 . [0003] my country's imported logs are widely distributed, including nearly 100 countries and regions on five continents including Africa, Europe, America, Oceania and Asia. At the same time, there are many types of logs imported, including r...
