[0043] In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In order to avoid confusion with the present invention, some technical features known in the art are not described.

[0044] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside in the figures shown in the present utility model, and are explained here together.

[0045] The connection method can be bonding, welding, bolt connection, etc., depending on actual needs.

[0046] Please refer to Figure 1-Figure 11 The hazardous waste storage cabinet control device shown includes a storage cabinet body 101, an air conditioning system 2 acting on the storage cabinet body 101, and a treatment cylinder 3 arranged on the top of the storage cabinet body 101. The storage cabinet body 101 is a cavity structure with an opening on one side. A circular hole 103 is opened on the top wall of the storage cabinet body 101. A cabinet door 102 is set on the open side of the storage cabinet body 101. After the hazardous waste is placed, the cabinet door 102 is closed to separate the hazardous waste.

[0047] In order to be able to handle the toxic gases produced, such as Figure 1-Figure 7 As shown, two groups of card blocks 106 are arranged on the top wall of the storage cabinet body 101, and each group of card blocks 106 is clamped with an activated carbon plate 107. A storage rack 11 is arranged in the storage cabinet body 101, and the storage rack 11 is composed of an upper and lower storage board 111. Two groups of card blocks 106 are arranged on the bottom surface of the upper storage board 111, and each group of card blocks 106 is clamped with an activated carbon plate 107. The activated carbon plate 107 is used to absorb the activated carbon. Toxic gas, a limit ring 104 is arranged on the top of the storage cabinet body 101, the limit ring 104 is coaxial with the circular hole 103, a fan 105 is arranged in the circular hole 103, the treatment cylinder 3 comprises a sleeve 301, the bottom end of the sleeve 301 is inserted in the limit ring 104, and an activated carbon layer 302, a weak acid layer 303 and a weak base layer 304 are arranged in sequence in the cavity of the sleeve 301, wherein the order of the weak acid layer 303 and the weak base layer 304 can be changed, and The weak acid layer 303 and the weak base layer 304 are both designed to be breathable materials. When the toxic gas passes through the weak acid layer 303 and the weak base layer 304, the sulfur dioxide, nitrogen oxides and other gases in the toxic gas can be consumed, thereby achieving the effect of purifying the toxic gas. A gas concentration sensor 133 is arranged on the top of the inner wall of the storage cabinet body 101. The gas concentration sensor 133 is close to the circular hole 103. When the toxic gas concentration monitored by the gas concentration sensor 133 is between the set value (the set value is a range with a smaller concentration value, and the adsorption of the toxic gas can be completed only by the activated carbon plate 107), the gas concentration sensor 133 does not transmit a signal, and only the toxic gas is adsorbed by the activated carbon plate 107. If the monitored toxic gas concentration exceeds the set value, the fan 105 will be started to allow the toxic gas to pass through the treatment tube 3 for treatment.

[0048] If someone supervises the operation of the hazardous waste storage cabinet in real time, there is no need to keep the processing tube 3 on the top of the storage cabinet body 101. The sealing plate 108 can be used to cover the limit ring 104, and the toxic gas is only adsorbed by the activated carbon plate 107. When the concentration of the internal toxic gas is too high, the processing tube 3 can be put on in time after the sound and light alarm 122 sounds an alarm. This method can increase the working life of the processing tube 3.

[0049] In order to adjust the local temperature and humidity inside the hazardous waste storage cabinet, Figure 7-10 As shown, the air conditioning system 2 includes an air conditioner 201 and a motor 211. The air conditioner 201 is connected to a ventilation pipe 202. The ventilation pipe 202 is provided with a plurality of air outlets 203. The plurality of air outlets 203 are distributed in a rectangular array, and the positions of the air outlets 203 correspond to the temperature and humidity sensors 132 one by one. The ventilation pipe 202 includes two delivery pipes. The two delivery pipes correspond to the two storage plates 111. When the air conditioner 201 is working, the cold air can be delivered to the top of the two storage plates 111 through the two delivery pipes to cool the environment where the hazardous waste is located and remove the internal Water molecules in the air are removed, several motors 211 are arranged, and each air outlet 203 is provided with a motor 211, and the output shaft of each motor 211 is coaxially connected with a screw rod 212, and each screw rod 212 is threadedly connected with a threaded sleeve 213, and the bottom end of each threaded sleeve 213 is connected with a matching plate 214, and the matching plate 214 matches with the air outlet 203. When in use, the matching plate 214 is driven to move by the motor 211, and the matching plate 214 and the air outlet 203 can form a gap for air outlet, and the size of the air outlet gap can be adjusted by the matching plate 214 to change the size of the wind force.

[0050] like Fig.11 As shown, this is the control system of the hazardous waste storage cabinet control device. A central controller 121 is provided on the outer wall of the storage cabinet body 101 cavity, and an audible and visual alarm 122 is provided on the top of the storage cabinet body 101. The central controller 121 collects signals transmitted by the temperature and humidity sensor 132 and the gas concentration sensor 133, and then transmits the signals to the audible and visual alarm 122, the air conditioner 201, the motor 211 and the fan 105 to control whether they are working.

[0051] Several fixing rings 131 are arranged on one side surface of the cavity of the storage cabinet body 101, and the several fixing rings 131 are distributed in a rectangular array. Each fixing ring 131 is provided with a temperature and humidity sensor 132, and multiple positions can be detected by multiple temperature and humidity sensors 132. After the signal is transmitted to the central controller 121, the signal is transmitted to the air conditioner 201, the motor 211 and the sound and light alarm 122. The air conditioner 201 and the motor 211 are used to change the temperature and humidity in the internal environment of the storage cabinet body 101. The sound and light alarm 122 is used to let the supervisor know the internal situation. After the signal collected by the gas concentration sensor 133 is transmitted to the central controller 121, the signal is transmitted to the sound and light alarm 122 and the fan 105. The toxic gas is processed by the cooperation of the fan 105 and the processing tube 3, and the supervisor is informed and processed through the sound and light alarm 122.

[0052] How it works

[0053] When placing hazardous waste using the hazardous waste storage cabinet control device, the hazardous waste is placed on two storage plates 111 and is placed directly in categories. The temperature and humidity of multiple positions in the cavity of the storage cabinet body 101 are monitored by a number of temperature and humidity sensors 132. If a certain position has a high temperature or humidity, the temperature and humidity sensor 132 there transmits a signal to the central controller 121, and then the central controller 121 controls the motor 211 there to work, so that the opening formed by the air outlet 203 and the matching plate 214 there becomes larger, thereby increasing the air conditioning wind force there. If a power outage or other factors occur during use, causing the internal ambient temperature of the hazardous waste storage cabinet to exceed 30°C or the humidity to exceed 80%, the hazardous waste will produce toxic gases. If the concentration of the toxic gas is between the range values ​​set by the gas concentration sensor 133, the gas concentration sensor 133 will generate toxic gases. The activated carbon plate 107 is provided to absorb the toxic gas. If the amount of toxic gas generated exceeds the range value set by the gas concentration sensor 133, the gas concentration sensor 133 transmits a signal to the central controller 121. The central controller 121 controls the sound and light alarm 122 to work, makes a sound and turns on the light, and controls the fan 105 to work. When the fan 105 is working, it blows the internal gas of the storage cabinet body 101 to the processing tube 3. Under the action of the activated carbon layer 302, the weak acid layer 303 and the weak base layer 304 on the processing tube 3, the toxic gas can be processed. At this time, the gas concentration sensor 133 continues to monitor. When the toxic gas concentration in the cavity of the storage cabinet body 101 monitored by the gas concentration sensor 133 drops to the set range, the gas concentration sensor 133 transmits a signal to the central controller 121, and the central controller 121 controls the sound and light alarm 122 and the fan 105 to stop working.
